Charge your phone battery directly with the circuit. We charge the phone battery without the phone. The safest way to charge the battery without a phone

Manufacturers use lithium-ion batteries in popular phone models. Their main feature is increased capacity and reliability. But despite this, energy consumption is increased. You have to exercise several times a day. Sometimes this situation forces you to purchase a new battery. It would be a good idea to charge your phone battery without the phone. Especially when the charging socket is broken.

Is it possible to charge a phone battery without a phone?

Let's say there are 2 batteries and 1 phone. In this case, alternately filling the batteries with energy is not convenient. And it will take a lot of time. In addition, constantly removing and putting on the cover leads to damage to the latches. After a while it may not close and the battery will fall out.

It is best to charge additional batteries separately from the phone. There are several ways to charge your phone battery without a phone. These include specialized and homemade methods. It is advisable that the smartphone's battery be removable.

Attention! If you plan to frequently charge additional batteries, take a special device. Homemade recharging methods are best used in extreme cases.

What do you need to know when performing direct charging of your phone battery?

Before charging your phone battery without your phone, consider the following:

1. Only a factory device will give a good charge. Homemade can be harmful.
2. When charging at home, take into account the current, voltage, and resistance. If you do not adjust the parameters, the current will not flow to the battery. If you twist the battery, it may be damaged.
3. You should monitor the process. When heating, disconnect the charging element.
4. Strictly observe the current characteristics.
5. Improper charging methods can damage the batteries.

It is recommended to use homemade methods at home for those who can distinguish plus from minus and are able to control voltage and current.

Ways to charge your phone battery without a phone

The best way to charge a battery with energy is to use a factory charger. You can also use a direct connection via a phone charger or charge from a PowerBank.

With the help of a frog

This is an industrial charger that got its name because of its specific appearance. It can be used to recharge removable batteries.

Algorithm for charging a phone battery without a phone using a frog:

• Turn off the power to the smartphone and take the battery out.
• Clarify where the positive and negative contacts are. Usually there are inscriptions “+” and “-”. If not, then determine the polarity with a multimeter.
• Lift the cover of the Frog Memory. Pay attention to where the plus and minus are.
• Place the battery into the device. To do this, move the sliders with the contacts so that their poles coincide with the battery.
• Close the cover; it will secure the power source.
• Connect the device to a power outlet. The red light will come on. If the reaction is different, then the connection is incorrect.
• When you see a green light, you can disconnect the battery from the charger. This indicates that it is charged.

The main advantage of the frog is its safety. If the battery is connected to the contacts incorrectly, the charge will not flow. But the battery will be completely safe.

Direct connection to power supply

There are 2 ways:

• Take an old adapter with the required characteristics. Strip the plug and cut off the wiring. Find out the polarity using a tester and connect directly. The best power supply will be a five-volt power supply with a current of 2 A. You can also use a device with a voltage of 9-20 volts and a current of up to 5 amperes. For example, from a laptop computer. But there is a risk of damaging the battery. To prevent this from happening, you need to connect a resistor to the positive contact. And through it, transmit current to the wire.
• Connect two wires to the plug. Observing the polarity, connect them to the battery and wrap everything with tape.

Attention! The battery has a controller that controls charging. It does not allow the battery to be recharged and does not start a battery with a voltage of more than 5 v. If it does, turn off the heating device.

From AA batteries or rechargeable batteriesPowerBank

You can recharge using regular batteries or batteries. To do this, take a box for 4 batteries. The output should be 6 volts. Check with a multimeter. The capacity of each individual energy source should be 1.5 volts. Observing the correct polarity, connect the wires from the assembled power bank to the phone battery and charge without the phone. Whether or not the battery is charged depends on the capacity of the energy sources.

The circuit uses a 2 ohm resistor. This is required so that a voltage of 5 volts drops across the battery. But if you don’t install such a resistance, nothing will happen to the battery, since there is a controller.

How to squeeze the last charge out of your phone battery without a phone?

Sometimes it happens that you need to make one single call or go into the phone for a couple of minutes to look at some data. In this case, emergency measures will come to the rescue.

Transparent tape for battery labels

This method is simple and safe. It will help you squeeze out a charge for a couple of calls at home.

Algorithm of actions:

1. Turn off your mobile device.
2. Remove the battery.
3. Cover the battery contacts with tape.
4. Reinstall the battery.

This approach allows you to squeeze out a little charge and do the bare essentials.

Heat and pressure

These methods are suitable if there is a very extreme case. Most often, such methods damage the battery.

• You take out the battery, heat the metal plate and place the battery on it. You can also use a stove, but it is too dangerous.
• Deformation. The battery needs to be squeezed a little. For example, throw it on the floor or squeeze it with your hands.

Attention! Refer to the operating instructions. It states what can be done with the battery and what is prohibited.

What effect do these methods have on the phone's battery?

The simplest and safest method is to charge through a frog. The option where regular batteries are used is also not harmful, but it is not very reliable. If the battery is already discharged initially, then nothing may come out. In addition, you will have to make a special case with protruding wires.

Direct connection via a power supply is quite risky. If you neglect the parameters, you can damage the battery.

Emergency methods are all dangerous, except for the adhesive tape method. Heating is harmful, but deformation is even worse. Too much force and you can damage the battery and not make a call.

It is best to carry a charger or Power Bank with you.

Is your smartphone's MiniUSB socket broken? Or do you only have a battery on your hands without a mobile device? Figure out how to charge your phone battery without a phone. This can be done directly. But precautions must be taken. This way you will keep the device in working condition. And you will use it even if the USB connector breaks down.

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

If you're wondering how to charge your battery without your phone because it's broken, take it in for repair. It is better to repair the device rather than damage the battery. The direct charging method is a temporary solution. It is suitable when you urgently need a mobile phone, but it is not possible to power it in the usual way. But you cannot constantly charge the battery separately from the smartphone.

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

This is not the best option, since you won’t be able to charge your smartphone’s battery without your smartphone. And it will be replenished slowly. But if your mini-USB slot just isn't working, wireless power transfer will be easier and safer. Nothing will break or explode with it. A significant disadvantage is that the necessary equipment is expensive. Other methods, although risky, are available to everyone.

To decide how to charge the phone's battery directly, you need to remove it from the case. If it is not removable, you won’t be able to “get” to the contacts. And you shouldn’t manually refill the battery while it’s in the smartphone.

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 you are using one, the second is charging. It is also worth mastering the methods of charging a phone battery without a phone for those who have a broken socket or the phone simply does not turn on and it is not clear why.

Is it possible to charge a phone battery without a phone?

It is inconvenient to charge two or more batteries in turn through the same telephone set and there is not always time or opportunity. Moreover, frequent opening and closing of the device cover can lead to breakage of its clamps, as a result - it will simply stop holding 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 being used for its intended purpose. And this is quite possible. This can be done in different ways. Among them there are both special devices and homemade methods, from more advanced to completely primitive opportunities to extend the life of the battery even 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 some degree of risk.

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

What to consider when charging your phone battery directly

Before using battery charging methods separate from your mobile device, you need to consider the following:

1. Only a special charger can provide a full battery charge; 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 there is excess, 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 monitor the current parameters using a multimeter during the charging process.
5. Incorrect actions during home methods for restoring charge can lead to battery failure.

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

Methods to charge a phone battery without a phone

The most acceptable ways to charge the battery are to use a universal charger, connect directly via an adapter, or from several regular or rechargeable batteries.

From a universal memory (Frog)

A universal charger, popularly called a “frog” because of its specific appearance, is sold in various electronics stores and is used to separately charge the batteries of phones, tablets, cameras and other removable oversized batteries. This is a convenient device for those who need this constantly.

How to use:

1. Turn off the phone and remove the battery.
2. Find out which contact is positive and which is negative. Usually they are signed, but if not, this can be done using a multimeter.
3. Open the cover of the universal charger. Inside it there are two terminals with marked polarity.
4. Insert the battery into the frog, move the sliders with the terminals apart so that they coincide with the battery contacts. Plus - to plus, minus - to minus.
5. Close the cover, which will securely fix the battery.
6. Connect the device to the network. The red light should light up. If not, the battery is not installed correctly.
7. When the red light turns green, the battery is fully charged and can be removed.

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

Directly using an adapter

There are two options here. For the first, you will need an unnecessary adapter with suitable parameters. You need 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 would be 5 volts, 2 amperes. If a suitable one is 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 risks causing the battery to fail. To avoid this, you need to insert a resistor of the required resistance into the positive wire gap. The second option is suitable if the adapter is used and needed in its entirety, then you will need thin wire and electrical tape, and also know where the adapter plug is plus and where is minus. The first is located inside the plug hole, the second is outside. Therefore, you need to respectively insert the wires with stripped ends and secure them with tape or 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 prevents 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 AA batteries or rechargeable batteries

You can charge your smartphone's battery using regular or rechargeable AA batteries. You will need a special device where they are inserted in four pieces, which has conclusions. Batteries are needed with a capacity of at least 1.5 volts.
Batteries should be inserted into the structure, and its terminals should be connected to the phone battery contacts, observing the poles. The success of charging 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 receives exactly 5 volts and not 6, but there is no particular need for this, since nothing will happen to the battery if the controller is working properly.

How to squeeze the remainder out of your phone battery

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

Scotch tape for contacts

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

Oddly enough, such a primitive method gives a chance to make one or two important calls, and does not harm the device as much as the following methods.

Heating or deformation

The following 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 only use them if the call is a matter of life and death.

The first involves heating the battery. To do this, you need to take it out of 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. In the same way, ordinary batteries are bitten in order to slightly extend their life. The phone battery must be thrown sharply 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 full charging and will not cause 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 via an adapter has certain risks. If you do not take into account voltage and resistance, you can ruin the battery.

As for methods of emergency battery resuscitation, the only safe method among them is the method with adhesive tape. Heating does damage, but not as much as deformation. In most cases, after this, this emergency call will be the last for the battery. You can also overdo it with heat or shock, and damage the battery right away. 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 truly critical situation. What if one call could save a life?..

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

All owners of cell phones have encountered such a problem as an untimely discharged battery. Of course, if you have a charger and an outlet at hand, the problem can be solved in a matter of minutes, but what if the charger is broken and you urgently need to make a call? Read our instructions and you will learn how to charge your phone battery directly.

Let's consider several charging methods:

Ways to charge your phone directly

First and the easiest way to charge your phone battery directly is using a computer or laptop. Take a USB or Micro USB cable, insert it into your phone and then into your PC. After this, charging will start automatically.

Second way more labor-intensive, but useful if you don’t have a computer at hand:

• We take a battery and an old unnecessary charger from any phone. Cut off the connector and expose the wires.
• Remove the battery from the phone and carefully connect the wires. We connect plus with plus and, accordingly, minus with minus. For secure fixation, you can use tape or tape.
• Plug it in.

Attention! When charging your phone battery directly, be careful not to touch the wires when charging has started, as this can have a detrimental effect on your health.

Third way

You can buy a universal charger in advance that fits all batteries. When your phone is discharged, just take out the battery and insert it into the charger. If you can’t buy one, then make a temporary charging battery yourself. To do this, buy two AA batteries and a box in the store. Solder the connector to the box, and at the right moment, connect the homemade device to the phone.

Now you know whether it is possible to charge your phone battery directly and can use any method if necessary.
