Charger failure, low-quality or non-original adapter, lack of electricity. These and many other reasons may prevent a user from charging an iPhone. However, just for such a case, there are many other modern ways to recharge the device.

If you don’t have an original charger at hand, and the battery is almost running out, then you can use one of the following simple methods. Most of them can be a worthy alternative to Lightning.

Via USB port

If you only have a USB cable at hand, you can use it and a computer to charge your mobile device. USB 2.0 and 3.0 connectors are suitable for this. The disadvantage of this method is that the cable does not have enough power, so it will take a lot of time to achieve 100% charge.

If you connect the USB cable to the adapter, you can use a wall outlet instead of a computer. This method will be faster, but you will need to wait up to several hours.

Charge without a cord

There are two options for alternative power sources that are offered on the modern market:

• solar battery. It is a portable device that accumulates solar energy and can transfer it to a mobile phone in the form of cherished battery percentages. Naturally, in cloudy weather it will be difficult to use a solar battery;
• portable accumulator. It can be wired (requires a USB cable) or wireless. You can purchase a device in a price range from 500 rubles to several thousand. The only difference will be in power: the more powerful the “charger”, the more expensive it is. The optimal power level is considered to be 10,000 mAh.

In order for the battery to supply energy to the mobile phone in a difficult situation, it must also be recharged in a timely manner.

Note! Another lesser-known device is a device that converts heat into electrical energy. It is installed directly on the fire (or near it), after which it is connected to the mobile phone. This method is ideal for hiking or other conditions in which it would be difficult to obtain electrical energy.

iQi Mobile wireless charging

An innovative device from the manufacturer Apple is an original battery that charges a mobile device contactlessly under any conditions. The advantages of the iQi Mobile Wireless Charging device are:

• affordable price;
• light weight and compact dimensions (convenient to take with you on the road);
• the ability to place the device under a mobile case;
• no need for electricity sources;
• the ability to charge the gadget;
• high charging speed;
• compatible with all iPhone models including X, 7 Plus, SE, etc.;
• work without using a USB cable.

All that is required for operation is a compatible Koolpuck or Koolpad charger. It is enough to place the wireless charger nearby and the battery percentage will begin to increase quickly.

Case with battery

The battery case is an innovative development, invented for those who constantly need to charge their phone when there is no network nearby. This device works in the following way:

1. We install the mobile phone inside. To do this, pull back the top edge and insert the device.
2. Charging. While in the charging case, the iPhone works automatically. To avoid wasting excess energy, monitor the level on the screen of your mobile device.
3. Remove from charge. To do this, pull back the top edge and take out the phone.

Note! The charging case also needs to be recharged. To do this, use a USB Lightning cable and any user-friendly energy source. You can use a licensed “charger” for iPhone.

Since this case is not equipped with any indicators, its charge level must be monitored through the Apple device. To do this, place the phone on charging in the case, after which two battery indicators will be displayed on its screen - the main one and for the Smart Battery Case.

What to do if your iPhone won't charge

Sometimes you cannot charge your mobile device, even when you have the original charger at hand. Knowing the causes of this phenomenon, you can try to correct the problem at home. Let's consider possible solutions:

• faulty USB port. Problems with the laptop may result in problems with the USB connectors. If you charge your iPhone this way, test all ports, constantly monitoring the charge level. Often this method helps, and charging still begins in one or more ports;
• Lightning connector is dirty. This happens even if you use a case and keep the device completely clean. Try cleaning the connector with a toothpick, but be careful not to damage the internal contacts. It is best to carefully walk around the corners without touching the central part. After this, the input should be purged and you can start charging.

If the phone is so discharged that it turns off, it naturally may not immediately respond to the charger. Wait 10-15 minutes before moving on to the next method.

If neither one nor the other method helped, but you are using the original charger, then most likely the problem lies in the mobile device itself. Problems may arise with the battery, firmware, or power controller. In this case, you will need to contact a service center for diagnostics and subsequent repair work.

We use other chargers

Any specialist will confidently say that for high-quality iPhone charging, it is best to use the original device. But this is not always possible, and besides, certified models are quite expensive. In such situations, users resort to using other chargers, for example:

• Chinese analogues. Using cheap analog chargers is an effective way to charge your mobile device. It's cheap, but very short-lived.
• direct charge. This method is very dangerous, however, experienced users can take risks and use it. To implement this, you will need to disassemble the iPhone and remove the battery. After this, carefully cut off the connector from any charger: you will see blue (+) and red (-) wires. We connect these wires to the contacts on the battery and secure them with electrical tape. It will be impossible to control the charge level, but if everything is done correctly, then rest assured that the device will be charged. If you are not sure that you can organize the process safely, then it is better not to use this method!

The described methods may be suitable only for the most extreme cases and for one-time use. It is strictly not recommended to use them constantly: this can cause harm to both the mobile device and your health.

What is better not to do

Sometimes iPhone users who cannot charge their device take extreme measures to do so or neglect safety rules. Such users should know in advance what they should absolutely not do:

• constantly use uncertified chargers. There are hundreds of cases of mobile phone fires, battery failure, and serious breakdowns. The causes of these problems were non-original chargers. Cheap analogues will do your iPhone a disservice, so it is better to pay more, but buy the original Lightning;
• try to disassemble the phone yourself. You should especially not do this if you are not mobile savvy. You can be sure that as a result you will have to contact a service center;
• Do not leave your mobile charging after the battery is fully charged. This has a big impact on the battery and shortens its life;
• follow the instructions. Additional charging devices must be used strictly in accordance with it. Do not neglect safety rules and the battery will last you a long time.

Important! Experts recommend keeping charging at a medium level. It ranges from 40% to 80%. It is better not to bring the charge level to 100% and not to let it drop to 0%: this wears out the battery. The ideal option is to charge the device more often, but for a shorter period of time.

Results

There are many devices, including non-standard ones, that help charge the iPhone even in difficult conditions. However, it is not recommended to use them constantly, but only in rare cases. The best and safest way to charge is the original device.

The process of charging a laptop without using a charger is a rather difficult, but quite doable task. In this article, we will tell you in as much detail as possible about ways to implement means of recharging a laptop if you do not have a native and, importantly, working power adapter.

Due to the fact that the actions of charging a laptop without a power adapter require direct intervention in the operation of the laptop computer, it is important to make a note regarding the automatic solution to problems with turning on the device without using a battery and charger. Thus, after carefully studying the instructions, you can not only replenish the battery energy, but also make the laptop work without a built-in power source at all.

Among other things, you should understand some additional aspects that include possible computer problems and are directly related to the reason for the need for this type of charging. Going deeper into the essence of what has been said, before following the recommendations from the instructions, be sure to make sure that the laptop is in working order.

Be extremely careful when performing any actions not originally intended by the manufacturer! In general, even after strictly following the recommendations, we cannot guarantee that the device will charge to normal levels. Moreover, complications may well occur, for example, in the form of a short circuit and burnout of the laptop’s internal power components.

Method 1: Charge the battery without a laptop

This method of charging a laptop consists of disconnecting the battery itself from the laptop computer and, by using some tools, replenishing the energy supply. In this case, you may still need a power adapter from the laptop, which, however, is quite possible to replace with any other that meets the requirements of the technical specifications.

Please note that as part of our detailed instructions for this method, we also covered the possibility of replacing the battery with a new component. Based on the topic of this article, these notes may well be useful, since by replacing the old discharged battery with a charged new one, it is possible to restore the laptop to full functionality.

Method 2: Use a direct connection

By analogy with the first method, this method is extremely radical and is intended for users who, at a minimum, have had experience working with certain electrical appliances. Despite this, of course, even a beginner can cope with the required tasks, however, if the slightest doubt arises, it is better to go straight to the next section of the article.

A laptop can become unusable due to incorrect actions and violations of safety rules.

Moving on to the essence of the direct connection method, it is important to make a reservation about the small number of existing methods. As a result, no matter which charging option you choose, you are faced with certain requirements that are generally equivalent to purchasing a new charger.

Having decided on your priorities, you will need to prepare in advance a couple of small wires with soft copper cores and any sufficiently powerful external power supply, the voltage from which should at least be equivalent to a standard adapter. Please note that if there is a lack of voltage, the battery will still be charged, but not completely.

The lack of voltage of the power supply used will most likely manifest itself in significant declines in the performance of the laptop.

To avoid problems, you should work with the laptop turned off and the power adapter unplugged. It is also advisable to remove the battery until a channel for transmitting electricity to the laptop is established.

• center - «+» ;
• edge – «-» .

The neutral line usually passes through the negative terminal.

For reliability, use a plastic tube or make the positive pole winding yourself.

One way or another, your goal is to fix the wire to the middle segment of the charging socket by any means.

The negative pole should be dealt with in the same way, but in this case the wire should only contact the side metal frame.

Additionally, you should make sure that the contacts do not intersect, for example, by using a multimeter.

Once you've finished connecting the wiring, you can move on to the power supply, depending on its value.

In addition to what has been described, you can do things a little differently.

When the adapter you choose is slightly more powerful than the original one, you should take special care to prevent overheating of the laptop components and the battery itself.

This is essentially the end of the method, since after following the recommendations all that remains is to install the battery and wait for it to fully load.

Method 3: Use USB ports

As you know, today a fairly large number of possibilities are provided by standard USB ports available on literally any laptop computer. These additional features rightfully include charging the battery without using the original charger.

It should be noted that although special cables can be purchased without any problems at any electronics store, they still have certain requirements for the device being charged. This directly concerns the presence of a modern USB 3.1 port on a laptop computer, capable of transmitting the necessary impulses.

You can find out about the presence of such an input by reading the technical specification from the computer, which describes all the available ports. Typically the socket you need is called USB 3.1 (Type-C).

So, how to charge a laptop without charging via USB:

Of course, thanks to this approach to replenishing energy in batteries, you can use all the capabilities of laptops without any visible restrictions.

Method 4: Use an external battery

This method, unlike others, allows you to charge your laptop not only at home, but also anywhere else. What's more, you still aren't required to charge a laptop as standard.

Please note that an external battery, called a Power Bank, is designed to charge not only laptops, but also other portable gadgets. Depending on the type of battery you purchase, you can charge several devices at once.

The devices shown in the screenshots within the article are not recommended - the choice is up to you.

Using this approach, especially if you have multiple drives, you can increase the standard laptop battery life limit to the same level as a standard power adapter.

Method 5: Use an auto-inverter

Many car owners and at the same time laptop users have encountered the problem of a lack of standard battery charge when actively using the computer on the go. In this case, the ideal solution to the problem is a special automobile converter that converts the base voltage of the vehicle.

It’s worth mentioning here that you can use such a device either with or without a standard power adapter. However, given that in your case there is most likely no charger at all, you will need an additional USB adapter.

In addition to the above, it is quite possible to purchase a car power adapter for your laptop and charge the computer using it through the cigarette lighter. However, such power supplies are usually supported by a limited number of laptop models.

This method, as you can see, is rather additional and is suitable as a solution in isolated cases.

Method 6: Use an electric generator

In modern realities, many users resort to using gadgets such as solar panels or any other portable generators to charge their personal devices. This attitude towards such types of recharging is quite justified, since the battery is often replenished quite quickly.

The main negative feature of such gadgets is their dependence on certain weather conditions, which makes using them at home somewhat difficult.

1. The first thing you need to do is purchase the device you need from an electronics store.



In our case, this is a solar battery, due to its maximum compactness.

2. Don’t forget to check with your consultants about the gadget’s power, touching on the topic of recharging your laptop.



3. When you have the device with you, use the appropriate adapter to connect the power generator to the laptop's charging socket.



4. Usually the required set of adapters is supplied with the gadget.



5. After connecting, make sure that the source works without any problems.



6. Over a period of time after starting, the energy will gradually transfer to the laptop's base battery.

Such generators are capable of storing voltage, being a kind of Power Bank. That is, for example, you can leave a solar battery in the open air and soon it will be able to power all your devices.

Storage capacity depends on the generator model.

This concludes the instructions.

Regardless of the battery charging method you choose, you will be able to replenish the battery's energy reserves. And although all methods are fairly equivalent, in the absence of the necessary parts and knowledge, it will still be much more profitable to acquire a new power adapter.

We often miss good shots in the forest or at sea, we may be late or stumble in the dark because a simple battery from a camera, watch or flashlight suddenly runs out. It's hard to say exactly when the charge will be used up, unless this is a Duracell model with an indicator. But don't despair! Thanks to a few tips, you can avoid unpredictable situations and take the intended photographs from a digital camera, find out the exact time, illuminate the road, etc. In this article, we will tell you how to charge batteries at home without a charger, which will make life much easier in unpredictable situations.

Know that to charge alkaline batteries you can use a special charger that can relatively quickly restore a discharged item. But each charging session will reduce its operating life by approximately 1/3. In addition, leakage is possible.

Note! At home you can charge: alkaline (alkaline) AA batteries. Don't: salt. The possibility of leakage or even explosion cannot be ruled out!

Charging can be done using various methods. Therefore, you should not throw away an element as soon as it stops serving. A few recommendations - and he’s back on track. The first method, using which you can charge AA batteries yourself without a charger. We connect the power supply to the network. Next, using the connection wires, we connect the used battery to the unit. Don't forget about polarity: plus is connected to plus, and minus is connected to minus. It’s quite easy to find where the “-\+” of a discharged object is: they are marked on the body.

Having connected the battery to the power source, wait until it warms up to fifty degrees and turn off the power. Next, wait a few minutes for the heated object to cool down. Otherwise, it may explode. Then, while the AA is still warm, it needs to be charged in a different way. It consists of the following: connect the power supply to electricity and disconnect it. This should take about 120 seconds. Next, we place the object to be charged in the “freezer” for 10 minutes, then take it out and wait 2-3 minutes for it to warm up. That's it, the charge is restored right at home without a charger! You can safely use it for the same computer mouse.

Main rules:

1. The charge is not feasible if you arrange the + and - in a different way. On the contrary, the battery will drain even faster.
2. It is permissible to charge the object at home 1-2 times.
3. Using the method described above, you can only charge simple AA alkaline batteries.
4. The charge can be carried out in any ambient temperature conditions.

Another charging method is the conventional heating method. But it is fraught with consequences (explosion). In this way, you can restore, again, small alkaline batteries at home. You can also charge them in a simpler way - place discharged objects in hot water, but for no more than 20 seconds, otherwise sad results are possible. Another simple way is to flatten or reduce the volume of the element with your own hands. This way you can charge various AA batteries. There is an example when a person, after the charge of a cast-ion battery had expired, simply took it out and stomped on it, after which the charge indicator showed one hundred percent.

You can also restore the charge without a charger this way: we make 2 holes with an awl near each carbon rod with a depth of three-quarters of the height of the element itself. We pour liquid into them and seal them, covering them with resin or plasticine. You can pour not just liquid, but an eight to ten percent solution of hydrochloric acid or double vinegar. Pour the solution several times to ensure sufficient saturation. This method allows you to charge up to seventy to eighty percent of the initial capacity.

Video instructions for restoring Duracell using phone charging

Another way to charge the product: open the cell cover with a knife. If the zinc cylinder, the object's rod and the carbon powder are intact, then immerse the object in the salt solution. Its ratio is as follows: 2 tablespoons of table salt per several glasses of liquid. Next, boil the solution together with the element for about ten to fifteen minutes. Then we return the gaskets responsible for sealing to their place and cover them with wax or plasticine.

How to charge your phone without a charger

Many have encountered a situation where the mobile phone battery is dead and there is nothing to charge it with. Or you are on a trip and forgot your charger at home, or you were late at work, and as luck would have it, your colleagues have phones of a different model. Or the charger has simply failed. Fell from the top shelf and broke, your beloved cat chewed the wire, or burned out due to a power surge - there are many cases that lead to the breakdown of the charger. And what to do when, for example, it’s late at night and you urgently need to make an extremely important call, or the charger broke on New Year’s Eve, and for a few more days it will be difficult to find a working mobile phone store? You can, of course, give up on everything and wait for an opportunity to purchase a new charger, or you can try to charge the phone without charging using one of the described methods.

Method one, computer - how to charge your phone without charging

You probably have a computer at home: a desktop, laptop, or even a tablet. The main thing is that it has a USB connector, and you have a corresponding adapter from the connector for your charger to USB. Now manufacturers have begun to adapt their connectors to mini- and micro-USB standards, so many users have several identical cables. If you have the necessary adapter or cable, but no PC, go to your neighbors, one of them will definitely help.

Method two, technical: how to charge a phone without a charger

Here you will have to do a little work and perform several sequential actions: Step 1: Find a charger You will need any working charger, for example, from an old unnecessary or non-working phone, or from a friend’s phone if he suddenly has an extra one. Step 2. Work with the cord Cut off the connector for connecting to the phone from the found charger. Then carefully use a knife to make a circular cut and remove the insulation so that two wires remain exposed: blue and red. Step 3. Connect to the battery and secure Remove the battery from your mobile phone. Carefully examine the golden contacts and look for the “+” and “-” markings next to them. Place the plus of the charger against the positive of the battery - this is the blue wire, and against the negative of the battery - the red one. Pressing the wires tightly against the contacts, secure them with electrical tape or tape. Connect the resulting device to the network. If you did everything correctly, the battery will begin to charge. Be careful to avoid electric shock, however minor, and try not to touch the contacts while charging.

Method three, finger, how to charge your phone without a charger

If you are going on a trip, a business trip or a hike, or a similar situation has already happened to you, then you can prepare for it accordingly. You can take a spare battery, or you can use a device that charges the phone via a mini-USB connector from regular AA batteries. Such devices are sold everywhere, which, however, does not deprive you of the pleasure of making it yourself from individual spare parts sold in radio parts stores.

Surely, most people are faced with the problem of their mobile phone battery draining when there is no way to charge it. This situation especially often arises on a trip, when your device signals that the battery is low and you suddenly realize that you left the charger at home and are wondering whether it is possible to charge the phone without charging. It also happens that the charger fails: it burned out, sank, broke, there are many reasons for this.

Is it possible to get out of a situation when you need to make an important call late at night, and the stores that sell chargers are already closed? How to charge a phone without charging and is it possible? Is it possible to charge the device at home? Such questions are relevant for anyone who has an urgent need to make a call, but does not have this opportunity due to the discharge of the mobile phone battery and the failure of the charger. These questions can be answered in the affirmative.

Methods to charge a mobile phone battery without using a charger

Method No. 1: computer

Almost every home has a personal computer, tablet or laptop. To solve the problem, devices must be equipped with a USB connector, and the arsenal must have the necessary adapter from the connector for your charger to a USB connector. Today, manufacturers have begun to produce connectors in accordance with mini- and micro-USB standards, so most users have several identical cables at once. If you have an adapter, but your personal computer has broken down, you can turn to your neighbors for help, who will definitely help you solve your problem.

Method No. 2: technical

This method requires the application of certain efforts and the implementation of several actions in a clear sequence.

A) Search for a charger

You need to find any charger in good condition, for example, from an old faulty mobile phone. You can ask your friends for an unnecessary charger.

B) Working with a cord

Disconnect the charger connector for connecting to your mobile phone. Then carefully use a knife to make a circular cut and remove the insulating material so that only two wires are exposed: red and blue.

B) Connecting to the battery and fixing

Remove the battery from the device. Carefully examine the gold contacts and determine where the “+” and “−” markings are located. Connect the plus of the charger (blue wire) to the positive of the battery, and connect the negative of the battery to the negative of the charger (red wire). When thoroughly attaching the wires to the contacts, secure them with tape or tape.

Connect the manufactured device to the network. If you have not made a mistake anywhere, the battery will begin to charge. Use caution to avoid electric shock. To do this, it is better not to touch the contacts while charging the battery.

Method No. 3: finger

If you intend to go on a trip or a business trip, then it is best to prepare for the fact that your mobile phone battery may run out on the road and you won’t have a charger at hand.

Take with you a device or battery that can charge your device via a mini-USB connector using regular AA batteries.

If you don't have a charger, how to charge your phone battery?

All mobile phone owners know very well how important it is to periodically charge their gadget. After all, if you don’t charge it in time, the phone becomes a useless brick. Now manufacturers produce models with huge displays, powerful processors and various additional “chips” that quickly drain battery power. So, you have to charge your smartphone almost every evening. Imagine that your phone charger has failed. Or have you lost it? It is clear that you can buy a new one. But by the time you order it online or go to the store yourself, time will pass. After all, you can’t stay without your phone all this time. In this article we will discuss what to do in such a situation and how to charge your phone battery without a charger.

Charging the battery from a computer or laptop

The first thing that comes to mind when you don't have a charger is to charge your phone battery from the USB port of your desktop or laptop. Yes, indeed, this is the simplest and most affordable option. After all, you will probably have a USB ─ mini or micro USB adapter. Most often, such adapters are included with the phone.

What should be noted about this charging mode? USB ports located on the front of a desktop computer should not be used to charge the phone's battery. The required charging current is not supplied through them. It is better to charge the battery from the rear USB ports. But even in this case, the charging current is limited to 500 mA. So, charging will take quite a long time. This should be attributed to the disadvantages of this method.

The advantage here is the safety of the process. When charging your phone battery from a computer or laptop, you will not damage it. A standard mains charger supplies a current of up to 2 amperes and, of course, in this case the process goes much faster.

This option is quite common since many people today have cars. Modern people spend a lot of time traveling to work and back home. It would be a sin not to use this time to charge your phone. In a car, a phone charger will replace your cigarette lighter to USB adapter, which will allow you to charge the battery.

There are a huge number of such devices in stores now. There are adapters with USB output. Then you will need to connect a USB ─ mini USB cable to it, and then your phone. There are models that immediately come with mini and micro USB output.

If you don't already have such an adapter, be sure to buy it. When choosing, pay attention to the length of the plug. Take the maximum length. Then it will fit all cigarette lighters. I had a situation where such an adapter in the cigarette lighter of a domestic car was not long enough. I had to redo it.
What if you only have a battery without a phone? Then read.

If you are often on business trips or tourist trains, then a power bank is a must. It will help charge the battery, including when you don’t have a phone charger at hand.

If you also have a tablet, then such an external battery is simply irreplaceable. Modern devices are very power hungry and may not last until the end of the working day if used actively. Therefore, even when you buy a standard network charger, the external power bank will not lie idle.

Frog – this is the popular name given to universal chargers that allow you to charge the battery directly without a phone.

The charger got its name from its characteristic appearance. This charger has a clamp, two width-adjustable contacts and several indicators. “Frog” allows you to charge many different batteries, regardless of their belonging to a particular gadget.

In general, conveniently fast and versatile.

If suddenly you cannot implement all other options, you can make a charger for your phone battery with your own hands from improvised materials. This way you can charge the battery if there are no other options.

What will you need?

• Power adapter 6─12 volts (router, microdrill, etc.);
• Two copper wires;
• Resistor;
• Electrical tape, plastic ties.

There are a number of recommendations on the Internet for making such homemade devices. To do this, the authors take an adapter, cut off its plug and strip the wires, which are then connected to the battery contacts. I see no reason for such vandalism. After all, the adapter is needed for use with your native device. Moreover, “+” and “-” can be taken using two wires.

• Strip two pieces of copper wire from both ends;
• You insert one into the plug and secure it with electrical tape. This is a plus;
• Tape the second one with electrical tape to the outer surface. This is a minus;
• Connect the remaining ends to the contact pads of the battery, observing polarity. To do this, you can use plastic ties or electrical tape.

The third contact is a temperature sensor. You don't need him.

To limit the charging current supplied to the battery, a resistor can be placed in the positive wire gap. Its resistance is calculated according to Ohm's law:

U – rated voltage of the power adapter in volts,

I – required current. It's better to limit it to 1 amp. To speed up the process, you can raise it to two.

The resistor power should be 0.5 watt or more. During charging, check the battery temperature by touch. If it gets too hot, stop charging and let it cool down. The voltage at the phone battery terminals can be monitored with a multimeter.

This is how you can charge your phone battery without a charger. As you can see, there are quite a lot of options. This will allow you to wait until you buy yourself a phone charger. By the way, if your USB interface fails, you can charge it using the methods described above for charging the battery directly. If you can recommend other ways to charge your phone battery without a charger, write in the comments. Vote in the poll and rate the article.

The once neglected mechanism of “technological dependence” is regularly gaining momentum today. Mobile phones and all kinds of devices powered by autonomous power sources have become an integral addition to our “omnipotence.” However, unforeseen life situations can encourage the user of the “benefits of civilization” to search for non-standard solutions.

A battery that runs out during a hike or a faulty charger is just a few of the reasons. However, it is precisely this kind of circumstances that will one day force your brain to produce “energy” thoughts about how to charge your phone if there is no charger. Your surprise will know no bounds when you learn about real-life methods, the implementation of which will allow you to make a call from a device whose battery has completely exhausted its energy resources. You will learn how to charge your phone using water, fire and other devices. Let’s not bore you, dear reader, let’s move on to specifics...

When the power outlet is useless: USB lifesaver

Intensive use, fluctuations in electrical energy or a banal defect... You never know what else can cause a faulty charger! And everything would be fine if not for one “but”... While waiting for an important call - oops! - battery containers are empty. Question “How to charge your phone if there is no charger?” will require prompt resolution.

As an option: a cable for synchronizing a mobile device with a PC (usually included in the sales kit) may well become a kind of “lifesaver.” Just connect your phone to your computer and the situation is saved!

Justified but definitely barbaric method

The hike is a good thing! But not every tourist is moderately experienced. A frivolous walk deep into the forest can be protracted. Naturally, the problem of “how to charge a phone without a charger” will not keep you waiting - the energy in the battery will run out. It is a well-known fact that an endless steppe, a forest, or the surface of a lake are not electrified places. Therefore, the charger you take with you on a hike is unlikely to be needed. Irony is inappropriate when a person is left alone with wildlife, but an emergency call can always be made, even if the battery has “died”. However, the latter will become inevitable after the “lost” person makes himself known.

How to properly charge your phone? Should it be discharged to zero before charging for the first time? How to properly carry out the first charge? How to choose a charger? If you search, you can find hundreds of answers on the Internet, which sometimes contradict each other! Where is the truth and where is the lie? Let's try to understand this difficult issue...

And so, the first thing that needs to be divided is the types of batteries in phones. They are divided into:

• Ni-MH (nickel metal hydride).
• Li-ion (lithium-ion).

And it’s immediately worth noting that nickel-metal hydride batteries have not been used for a long time. The vast majority of modern phones use lithium-ion battery types. If you are interested in all the details about the difference in technologies, I found a fairly detailed publication on this topic on Habré. And I will tell you literally in a nutshell in the simplest and most accessible language possible. Actually, due to the misunderstanding of these two types, various misunderstandings and myths about exercises arose. Because the older type did have a "memory effect", while Li-ion does not. But first things first...

In fact, the rules for charging modern phones have become so simple that after reading these rules you will laugh in the face of those who are still thinking about how to charge it correctly! :) In fact, I tried to lay out everything in as much detail as possible, and in the end it turned out to be a rather large text. That's why I divided it into two parts. In the first one, below, I described everything in detail, trying to justify each point from the technical part. But if you are not interested in this and only need point-by-point rules, scroll down the text, there I left a list of rules without unnecessary “technical garbage”.

The first thing to remember is that Ni-MH batteries actually had a memory effect, but if you bought something within the next five years, then with a 99% probability you have a Li-ion battery and you can forget this rule (I’m talking about "memory effect"). Li-ion, on the contrary, does not like deep discharge! And what’s more, if you drop him to zero, then on the contrary, it’s very difficult to “bring him back to life.” But the smart electronics of the phone knows this and turns off the device before you reach full zero. Although, of course, you shouldn’t forget about the human factor either. And constant attempts to turn on a discharged phone can lead to the fact that the electronics will not cope with their task. In this case, you should find the most “strong” charger, connect it and hope for a miracle. The phone will not immediately respond to it. I had a case when, after a complete discharge, the phone lay connected to the charger for almost an hour and showed no signs of life. However, then he came to life and went to charge. So don't let your device get to this point.

Although at the same time, too long an “overcharge” is no less harmful. If you keep the phone on charge for a long time when the battery is 100% charged, this will also lead to the death of the battery. And even more! Not just death, but to its swelling, and sometimes even to tearing! Of course, the smart electronics of the device are ready for this and prevent this in every possible way, but no smart electronics will protect you more effectively than simply turning off charging when the charge is complete.

So how do I charge my phone? You can’t recharge, you can’t discharge, you can’t either... What should I do? In fact, everything is simple. Charge your phone not when you have 1% left, but when the charge level drops below 20-30%. Charge to 100% and remove the charger. Of course, you shouldn’t run to your phone every five minutes and check, as soon as the charge has reached 100%, take it out immediately. If after the end of the charging cycle the phone remains connected to the network for half an hour or an hour, nothing will happen to it. The charge controller will simply disconnect the phone from the network and stop charging. But as soon as the phone is discharged to 99%, it will start charging again to 100%. This constant full recharging is what harms the power supply elements. Therefore, you should not leave your phone connected all night. But in an hour of lying after a full charge, nothing bad will happen to it.

And since we’re talking about the charge controller, it’s worth telling that you shouldn’t forget about it either. In fact, over time, from such discharges to 20-30% and charges, it may get a little confused and show not entirely accurate readings. Those. for example, the real level is 30%, but it will show you 20. What to do? It's actually simple. About once every month or two, still carry out a cycle of complete discharge and full charging! Yes, of course, this does a little harm to the battery, but it’s not so critical if such cycles take place once every month or two. This way you will periodically calibrate the charge sensor so that it shows the correct values.

Part 2. Briefly about how to charge your phone.

So what do we have in the end? Let's derive the rules for charging a mobile phone from all of the above:

• Don't overcharge. If the phone remains on charge for a long time at 100% charge, this will harm the battery.
• Full discharge is no less harmful. Do not allow the battery to become completely discharged. Place your phone on charge at about 20%.
• Once every month or two, carry out a full discharge/charge cycle to calibrate the phone’s charge sensor.
• Do not charge with short charges. It is better to charge normally once than 10 times at 8%.

That's all! If you see a small charge, charge it, and when finished, turn it off. Simple, right? :)

And further. On the Internet, I often saw advice that a newly purchased phone should be charged either overnight or for 12 hours... I would like to ask, why do this if the phone turns off charging when it reaches 100%? we'll talk about this separately about charging your phone for the first time.

At first, I would advise you to drop only the purchased phone to zero. It's not difficult to do. While you download the applications, while you get acquainted with the functionality, while you insist, the battery is gone. Then charge it to 100%. If you carefully read the publication, I think you should guess why to do this. It is advisable to do this not for battery operation, but in order to calibrate the charge sensor. In principle, the same procedure can be repeated a second time if desired, although it is not necessary. That’s all, after which you can start using your phone normally, taking into account all the rules written above.

Part 3. How to choose a phone charger?

Today, when choosing chargers, there is such a choice that you don’t know which is best to take. But in fact, it’s still simpler here than with the charging process itself. Today, fortunately, the days when each phone was charged through its own charger and when each phone had its own connector are gone. Today the micro usb standard dominates, which is successfully replacing the newer USB Type-C. But the connector doesn't really play any role in choosing the charger itself.

The first thing you should pay attention to is that the output current should not be lower than 2.1 A. Why not lower than 2.1 A? What is this parameter and what does it affect? Briefly and generally speaking, while the gadget is charging. On the device, the output current can be marked as “output” or “output”; the numbers indicated next to it indicate how much current the charger is capable of transmitting. To charge a smartphone, a current of at least 0.7 A is usually required. For a high-capacity tablet battery, about 2 A.

Very often you can hear the question, on the “native” charger the current is indicated, for example, 1A, what will happen if I connect the charger to 2A? Will your phone burn out? No, all modern smartphones are equipped with the power controller already mentioned repeatedly above, which does not take more than the smartphone requires. But if the phone can “use” this current, the gadget will charge faster. So it definitely won’t be worse, and perhaps even better.

In a nutshell, I would like to say about charging from a computer. Many people often charge their gadgets jn PC. Is it correct? Actually, yes and no. Those. If we are talking about charging small gadgets such as watches or simple old phones, then there are no problems at all. But if we are talking about top-end smartphones, tablets and other “heavy” devices, then everything is not so simple. At the time of development of these ports, it could not even be imagined that they might require a charging function. And that’s why their output current is only 0.5A. Now compare it to 2-3A charging tablet? Therefore, when you try to charge your brand new tablet, you put a huge load on the computer's motherboard.

Part 4. About data security.

Well, in the end I would like to say a few words about security not in terms of hardware, but at the software level. Have you ever thought that simple charging can cause a smartphone to not work not because of a burnt-out board, but because of viruses? Let's talk about this at the end.

The first thing you should pay attention to is the fact that both the connection to the computer and the connection to charging have been carried out in phones through the same port for a long time. This is of course convenient for the user, and also convenient for intruders who want to gain access to your phone.

A very illustrative experiment was conducted at the RSA security conference, which was held in San Francisco. Representatives of Authentic8 assembled a charging station at their stand and offered it to event participants. About 80 percent of conference attendees took advantage of the offer without even asking if it was safe.

"They were at an event where security issues were discussed, and they should probably understand such things. However, for some reason they did not suspect anything", explained the authors of the experiment.

Of course, the authors’ goal was not to steal data, but to show vulnerability. Therefore, the data was not stolen. The hack consisted of displaying the following message on their phone screens: " Please be safe and do not connect your phone to unfamiliar devices"However, in the same way you can not only play a joke, but also steal almost all the information from the device. From personal photos to registration data of social networks and bank card data. How to avoid this? Just follow simple rules:

It's best to avoid using public charging stations. Well, if there is no other choice, do not use the “built-in” wire, but find a regular outlet and use your own charger. This simple “life hack” will allow you to save not only your battery charge, but also your personal data.
