How to charge a phone battery. Three easy ways to charge your phone without a charger. With the help of a frog

Smartphones have long become an integral part of our lives. Due to their versatility, they have long supplanted ordinary phones from everyday use. After all, a smartphone allows you not only to make calls and send SMS messages, but also to fully use the Internet, communicate on social networks and find out the information you need.

But almost all smartphones have one significant drawback - the more often you use the phone, the faster the battery runs out. Often there are situations when the device is discharged at the most inopportune moment, and there is neither a charger nor an energy source at hand. But there is a way out of this situation. Now you will learn how to charge your phone without charging.

In what situations can you find yourself without charging?

In fact, there can be quite a lot of situations in which you can find yourself without a charger. The first of them is in case of its breakdown. This gadget is quite fragile. If dropped or handled carelessly, it breaks down very quickly.

Also, charging may be useless if you are on the road. In such a situation, in the absence of a source of electricity, you cannot use it to charge your mobile phone.

Of course, when a situation like this arises, the first thing that comes to your mind is to go out and buy a new charger.

But what if there is not a single store of mobile accessories nearby or a breakdown situation occurred at night? In this case, you urgently need to use the phone, which is discharged.

Note that even without a charger, you can always charge the battery.

Several ways to charge your phone without charging

First way not so universal, since you will need a laptop or a desktop computer for it. But at home it is quite possible to implement it.

You can charge your phone by connecting it to a computer, tablet or laptop using a USB cable. This cable is always included in the basic package of any smartphone. It is also universal, that is, it fits absolutely all telephones.

It is worth noting that charging the phone from a computer or laptop will be very slow. Therefore, this method will not help you out if you urgently need to hit the road and always have a working smartphone with you.

Second way charging may cause injury. In addition, if you follow the instructions incorrectly, you can damage your phone's battery. However, if everything is done correctly, then this charging method will definitely work. Also, it is not suitable for those smartphones that are equipped with non-removable batteries.

To implement it, you will need any old phone charger. As a rule, such things remain from old lost devices. From this charger, it is necessary to cut off the end that connects to the phone, and strip the insulation from the two wires under it. These wires will be insulated in two colors: red and blue. Then remove the battery from the phone and use electrical tape or tape to connect the red wire to the contact marked "minus" on the battery. In the same way, the blue wire is connected to the "plus". After fixing the wires, turn on the charger to the network. After turning on, do not touch the wires with your hands, so as not to suffer from electric shock.

Also, if you are going on a hike or a long trip in which you will definitely need a phone, you can build a charger for it yourself. To do this, you need to take a non-working charger, from which it will not be a pity to cut off the part that is inserted into the phone. Next, you will need several AA batteries, which must be connected in series with each other. It is necessary to solder the connector for charging the phone to the received home-made battery and use the resulting device as needed. For ease of use, all batteries can be placed in a small box.

Also very convenient today are external chargers, which already have a cord for charging the phone in their kit. Such devices can be pre-charged from the mains in a conventional manner. They can also be recharged with solar panels. Such accessories will be very relevant in nature, on the road, etc.

The small dimensions of the external charger will allow you to always have it with you and use it as needed. In addition, charging your phone with an external charger will not cause any problems and will not cause injury or damage to your smartphone. Due to their compactness and ease of use, these accessories are actively used by owners of mobile telephones.

People who spend a lot of time traveling, or for other reasons forced to use communication devices a lot, not being able to charge the phone battery as often as they need, are forced to look for ways out of this situation. Many find a solution to the problem in carrying several telephone batteries with them at once (we are not talking about smartphones with). But sooner or later all of them will be discharged and become useless. Charging each one individually inside the gadget takes too much time, it would be much more convenient to feed one battery while the second one is charging. In this regard, the question arises - how to charge the phone battery without a phone? You can make a device with your own hands, or you can buy a special device in a store for relatively little money. If you don’t really feel sorry for the battery of a smartphone, tablet, and the gadget is urgently needed, there are improvised ways to quickly charge the battery.

Battery box

It is possible to charge the phone's battery directly by building some kind of mobile charge storage for gadgets that is now popular - (this, by the way, is the best way).

To do this, a special box is taken for installing batteries, which are interconnected and have contact leads to the outside with the help of wires - you can get it at radio flea markets or electronics stores, perhaps it lies somewhere in the house. Several ordinary finger-type batteries are inserted there. You can bring out the contacts and directly connect them to the phone's battery, observing the polarity, or solder the connector to the output hole and directly charge the mobile phone itself.

With chargers

How to charge the phone battery at home separately from it, directly from charging?

Make a universal battery power device from any old device for powering gadgets:

1. Find some leftover charger in the house.
2. Cut off the connector that is inserted into the socket, carefully expose the wires. They usually come in blue and red. Blue carries a charge with a minus sign, and red, respectively, with a plus sign.
3. Connect the metal ends of the wires to the phone's battery, making sure that the polarity of the contacts matches - they must be signed on the battery, secure the connection with tape or electrical tape.
4. Wait about an hour for the battery to charge, then you can insert it into the gadget and use it.

How else to check the polarity of the wires?

Some charging wires may not have these standard colors, but some others. In such a situation, after all, you also need to somehow determine where which sign is. It is very easy to do this. All you need is a glass of water, in which you need to dissolve a little ordinary table salt.

1. The bare ends of the wires must be lowered into this glass.
2. Connect the device to the network (the main thing is not to touch the water and the wires themselves, otherwise you can get an electric shock).
3. Keep track of which wire the water began to boil and bubble. He is negative.

Charging from pieces of metal

It happens that you need at least a slightly charged phone battery somewhere in nature, where there are no old chargers or other similar devices. Is it possible to charge the battery in such a situation? Quite if you find more metal objects - pipes, corners and the like.

1. Take the found items and stick vertically into the ground.
2. Wrap with wire, preferably copper.
3. Bring out the ends of this wire like wires and connect to the battery.
4. Pour the metal part of the structure with an alkaline liquid, which is needed as an electrolyte. As alkali, you can use solutions of salts or soda, some chemical agents, if it is known that they contain alkaline compounds. The more metal there is in the structure, the stronger the current.

In order for the battery to last at least for a call, you can wrap its contacts with thin transparent tape or other adhesive tape. When you return to the place it will give a charge for a couple of minutes of work.

Heat

With more high temperature reactions begin to occur that take place when the battery is being charged. Therefore, you can try to replenish a small part of the charge in this way - attach the element to something hot or just rub it with your hands for a few minutes.

Deformation

The most risky method, which in almost all cases leads to a further malfunction of the battery, was seen by many in childhood. Some bit AA batteries to make them work. Here the principle is the same. If you lightly throw the battery on a stone or beat it on some other hard object, a small charge will accumulate, which is enough for a couple of quick actions or short conversations.

Homemade wireless charger

To make it, you will need:

• thin, no more than half a millimeter in diameter, metal (ideally copper) wire;
• diode;
• some knowledge of physics.

What then:

1. Make a flat coil of three dozen turns of wire.
2. Secure it with electrical tape or special glue on the phone battery.
3. Take a diode and connect the battery contacts with a spiral through it.

Use ready-made

Of course, manufacturers of accessories for gadgets did not stand aside and took care of those who like to feed batteries separately from equipment. For such cases, there is a charger for the battery of a phone or tablet that feeds it directly, which the common people called it because of its characteristic shape.

Using it is quite simple:

1. Turn off the device and remove the battery.
2. Decide where the contacts are positive and where negative.
3. Press on the edge of the frog lid to open it.
4. Inside the device there are two terminals that have polarity labels.
5. Put the battery contacts to the terminals so that the "pluses" and "minuses" match.
6. Close the cover, which will automatically lock the position of the battery.
7. Connect the device to the network and check if the red light is on. If it doesn't, the battery has been placed incorrectly and needs to be corrected.
8. When everything is connected correctly, it remains to wait until the red indicator changes to green - this means that the battery is charged and the “frog” has turned off the power.

There are many ways to charge a battery from any gadget, but it’s better to be prudent and have something with you that will allow you to safely replenish the charge, and not resort to extreme methods at all or only in emergency situations.

In modern mobile phones and smartphones use lithium-ion batteries, they are characterized by increased capacity and high reliability, although energy consumption has also increased significantly recently. This has led to the fact that now you have to charge the device even more often than before, and those who do not have time for this have to purchase a second battery. While one is in use, the other is charging. Also, to master the methods of charging a phone battery without a phone is for those who have a broken socket or the phone simply does not turn on, and why is not clear.

Maintenance

Is it possible to charge a phone battery without a phone

Charging two or more batteries in turn through the same telephone is inconvenient and there is not always time and opportunity. Moreover, frequent opening and closing of the cover of the device can lead to breakage of its clamps, as a result - it will simply cease to hold on over time, and the battery will fall out.

It is more convenient to charge additional batteries separately from the phone while the main one is used for its intended purpose. And this is quite possible. It can be done different ways. Among them there are both a special device and artisanal methods, from more advanced to very primitive ways to extend battery life a little more.

Important! If charging additional batteries is required regularly, then it makes sense to purchase a special device. It is reliable and durable. Home methods are best used only in emergency situations, because their use is always associated with varying degrees of risk.

The main thing is that your phone or smartphone has a removable battery.

Things to Consider When Directly Charging Your Phone Battery

Before using the battery charging methods separately from mobile device, the following must be taken into account:

1. A full charge of the battery can only be provided by a special charger, home methods in most cases can only partially correct the situation.
2. Using home methods, you need to take into account parameters such as voltage, current and resistance - if the parameters are insufficient, the battery will not charge at all, and if redundant, it may fail.
3. During charging, you need to carefully monitor the condition of the battery - if it gets too hot, the process must be stopped.
4. You should also control the current parameters using a multimeter during the charging process.
5. Incorrect actions during home recharge methods can lead to battery failure.

Therefore, it is worth the risk to those who are at least able to use a multimer, understand what voltage means, and know how to distinguish positive contacts from negative ones.

Methods to charge phone battery without phone

The most acceptable ways to charge the battery is to use a universal charger, connect directly through an adapter, and also from several ordinary or rechargeable batteries.

Universal charging frog

From the universal memory (Frogs)

A universal charger, commonly called a "frog" because of its specific appearance, is sold in various electronics stores, used to separately charge the batteries of phones, tablets, cameras and other removable oversized batteries. This is a handy device for those who need it all the time.

How to use:

1. Turn off your phone and remove the battery.
2. Find out which contact is positive and which is negative. Usually they are signed, but if not, you can do this using a multimer.
3. Open the cover of the universal charger. Inside it there are two terminals with signed polarity.
4. Insert the battery into the "frog", push the "sliders" with the terminals so that they match the battery contacts. Plus to plus, minus to minus.
5. Close the cover that securely fixes the battery.
6. Connect the device to the network. The red light should turn on. If not, then the battery is installed incorrectly.
7. When the red light changes to green, the battery is fully charged and can be removed.

The advantages of the "frog" is that it is reliable and absolutely safe. If you insert the battery incorrectly, then it simply will not charge, and will not fail.

Directly with adapter

There are two options here. For the first, you will need an unnecessary adapter with suitable parameters. He needs to cut off the plug and strip the wires. Using a multimeter, determine the polarity and connect directly to the battery contacts.

The optimal adapter is 5 volts, 2 amps. If a suitable one was not found, you can use a device up to 9-20 volts and 4-5 amperes - for example, from a laptop. But here a direct connection is fraught with the fact that the battery will fail. To avoid this, you need to insert a resistor of the required resistance into the wire break. The second option is suitable if the adapter is used and needed in its entirety, then you will need a thin wire and electrical tape, and also know where the adapter plug has a plus and a minus. The first is inside the plug hole, the second is outside. Therefore, you need to insert wires with bare ends accordingly and secure them with tape or electrical tape, and then connect them to the battery contacts.

Important! The battery has a controller - a board with a control chip that controls the charging process. It does not allow overcharging and does not allow the battery to exceed 5 volts, even if the charger sends 6 or more volts. However, if the battery gets very hot or something else goes wrong, the device should be turned off and all parameters checked again.

From finger batteries or accumulators

You can also charge your smartphone battery using conventional or rechargeable finger batteries. You will need a special device where they are inserted in four pieces, which has leads. Batteries need a capacity of at least 1.5 volts.
It is necessary to insert a battery into the design, and connect its leads to the battery contacts of the phone, observing the poles. Charging success depends on the capacity of the batteries, it may not be possible to fully charge the battery.

This circuit uses a 2 ohm resistor to ensure that the battery has exactly 5 volts, not 6, but there is no particular need for this, since nothing will happen to the battery with a properly functioning controller.

How to squeeze the leftovers out of your phone battery

There are also emergency situations when there is neither time nor opportunity to fully charge the phone's battery, but you urgently need to make a call or see some information. Then emergency methods will help.

Tape on contacts

The simplest and safest method to squeeze a little charge out of the battery at home is to turn off the phone, remove the battery, seal its contacts with tape and insert it back.

Oddly enough, such a primitive method gives a chance to make one or two important calls, while not harming the device in the same way as the following methods.

Heating or deformation

The next two methods also give you a chance to recharge the battery enough to make an urgent quick call. However, they harm the battery, so you should use them only if this call is a matter of life and death.

The first involves heating the battery. To do this, you need to remove it from the phone and, heating some metal object, apply it to it. The main thing is to prevent overheating.

The second method is even more dangerous and involves deformation of the battery. Similarly, ordinary batteries are bitten in order to slightly extend their life. The battery of the phone must be abruptly thrown onto a hard floor or hit against something.

How do these methods affect battery life?

The safest and most reliable way to charge the battery of a mobile device is to purchase a "frog". It will guarantee a full charge, and also will not bring any harm.

The battery method is also quite safe, but not always reliable. If the batteries themselves are partially discharged, then nothing may work, or it will work - but not completely. In addition, everything is not so simple here, first you need to mount a special device - a “box” for batteries with leads.

The direct connection method through an adapter has certain risks. If you do not take into account the voltage and resistance, you can ruin the battery.

As for the methods of emergency resuscitation of the battery, only the method with adhesive tape is safe among them. Heating hurts, but still not as much as deformation. In most cases, after this, this emergency call will be the last for the battery. And you can also overdo it with heat or shock, and disable the battery immediately. Then you won't be able to call even once.

You can experiment with wires as much as you like, if the phone battery is not really needed. If you don’t want to lose it in case of failure, it is better to resort to reliable and safe methods. But everyone also needs to know the extreme ones - in case of a really critical situation. What if one call could save a life?

Have you ever had such a situation - you really need a phone, and the battery is almost dead? Tell us in the comments how you managed to get out of this situation. This will help make the site content more complete and useful.

Is your miniUSB port broken on your smartphone? Or do you only have a battery on hand without a mobile device? Learn how to charge your phone battery without a phone. This can be done directly. But you have to take precautions. So you keep the device in working order. And you will use it even if the USB connector breaks.

IMPORTANT. "Extreme" charging harms the gadget. It's just not designed for that kind of connection. As a result, the device may fail. Better not to experiment. Don't do it just for fun.

If you are wondering how to charge the battery without your phone because it is broken, take it in for repair. It's better to fix the device than to ruin the battery. The direct charging method is a temporary solution. It is suitable when you urgently need a “mobile phone”, but you can’t power it in the usual way. But you can not constantly charge the battery separately from the smartphone.

There is a safe alternative - the transfer of energy literally through the air. The technology has appeared recently, so older smartphones do not support it. For wireless charging, you need a set of equipment: a charger (electromagnetic signal source) and a receiver that is attached to the phone's battery. The receiver itself can already be built into the gadget.

Is not the best option, since it will not work to charge the smartphone battery without a smartphone. Yes, and it will replenish slowly. But if you just don't have a mini USB slot working, transferring power wirelessly will be easier and safer. With it, nothing will definitely break or explode. Significant minus - necessary equipment it costs expensive. Other methods, although risky, are available to everyone.

To decide how to charge the phone's battery directly, you need to pull it out of the case. If it is non-removable, you will not be able to “get” to the contacts. Yes, and you should not manually replenish the battery while it is in the smartphone.

1. So, the first way is charging with a computer. This method will help if your charger is broken, and there is no opportunity to buy a new one right now. Take a cord with a USB plug on one end and a plug that fits your phone on the other end. We connect the cord to the phone and computer. Of course, the phone will charge much longer this way, but it should be enough for one important call.

2. The second method must be taken very carefully, and if you are afraid of the consequences, then it is better not to try it again. It is necessary to take any old charger from the phone, if you have one. We cut off the charging connector for connecting to the phone. Using a sharp knife, make a circular incision and remove the insulation, leaving the red and blue wires exposed.

3. Remove the battery from the phone and start charging it. Locate the negative and positive markings on the gold connectors on the battery. Connect the blue wire to the plus and the red wire to the minus. Press firmly and secure with duct tape or tape. When everything is done, turn on the charger. If everything is done correctly, the battery will start charging. ATTENTION! Never touch bare reins

4. Use the cigarette lighter in the car. To do this, of course, you need a special car charger, which you can buy at any hardware store. Get it for yourself and one day it will surely help you out. Insert the charger into the cigarette lighter and connect the phone.

5. Use a travel charger based on conventional AA batteries. Now in stores you can find a charger that can recharge using an internal power source. You just need to insert AA batteries and connect the connector to the phone. But if it is not possible to buy such a charge, proceed to the next step.

6. You can also do this exercise yourself. Take any charger and any device that runs on batteries, whether it's a razor or a radio. We cut the charging plug, insert the connector into the phone. And the stripped wires, observing the polarity, are connected to the batteries in the device. Turn on the device and enjoy the result.

7. In nature, you can use the help of a knife and fire. Warm up the knife blade and carefully place the battery on it with the contacts facing the blade. As a result, the battery will heat up and release some energy. Be careful with heating and do not overdo it.

8. After reading our article, remember that all tips are for informational purposes and we do not vouch for the safety of one or another of your devices. Be careful and act wisely in everything. Good luck and may the battery always be charged at the right time!
