What you need to know
Before you start charging your battery directly, you need to know the following:
- Only special chargers can perform a 100% charge of the battery, and home methods of charging the battery will provide only a partial charge.
- When using home methods, you need to take into account the current, voltage, and resistance, since at low values of these parameters charging will not be performed, and at high values the battery may completely fail.
- During the period of charging the battery, it is necessary to monitor the condition of the battery. If the battery starts to get very hot, this process must be stopped immediately.
- It is also necessary to monitor the current value. This procedure is performed using a multimeter.
If direct charging of the battery is performed incorrectly, it may be damaged. For this reason, such charging can be carried out by those who know how to use a multimeter and know how to find the voltage, and can also distinguish the positive contact from the negative one.
Tips for properly charging your phone battery
In conclusion, let us remind you how to properly charge your phone battery in normal mode. That is, in a mobile phone from a mains charger. Most modern smartphones use lithium batteries, lithium-ion and lithium-polymer. In order for such a battery to serve for a long time, the following rules must be observed:
- To charge the battery, use the “native” charger;
- Do not overcharge the lithium battery and do not discharge it to zero. It is better to maintain the charge in the range of 20-80 percent of the nominal value. These are the most comfortable working conditions for the battery;
- Calibrate your phone battery every 2-3 months. To do this, discharge it until the smartphone is dead, and then charge it to 100% while it’s off. After this, remove and insert the battery. If the charge is less than 100%, recharge it and repeat the test by removing and inserting the battery. Do this until the phone shows full charge when you turn it on ;
- If you put the battery in storage, then charge it by 50-60%. It is best to store at a temperature of about 15 degrees Celsius and avoid direct sunlight. Once every 1-2 months, carry out a battery discharge-charge cycle.
Charge the battery directly from the adapter without a phone
First, we'll tell you how to charge your phone battery directly with wires. To do this, you need to find any adapter that produces 5 V voltage and 1–2 A current. In extreme cases, a power supply from a laptop with parameters from nine to twenty volts and a current strength from four to five amperes is also suitable. In this case, a resistor with the required value is connected to the positive wire. As a rule, the “plus” and “minus” on the adapter plug are located as shown in the photo.
If the charger is not used for its intended purpose, the plug can be cut off and the terminals secured with tape directly to the battery terminals. Otherwise, the connecting wires are secured with tape at the negative output and tightly “stuck” into the positive “mother”. But you can also use springs.
It is better to connect a trimmer resistor, as this will allow you to regulate the charging current. This is not always possible; then a resistance with a calculated value is used. If, for example, there is a charger that produces 12 V, then according to Ohm’s law 12 V/1.5 A (charging current recommended by the manufacturer), we obtain the value of the required resistor of 8 Ohms. In practice, you can use a resistor with a resistance of 10–100 Ohms - as powerful as possible. Please note that a low-power resistor will get very hot and may even burn out.
Charge your phone without a charger or power bank: 8 ways
Suitable for: those who are used to storing unnecessary things
homesecurity
We do not recommend trying this charging method at home. This may lead to accidents.
What to do: You will need an unnecessary charger, for example, from an old push-button telephone. Cut the connector and carefully remove the insulation to release the two wires. These are your “plus” and “minus” - they are usually red and blue, respectively. If not, check the polarity in a glass of salt water: turn on the charger and immerse the wires in the glass one by one. The minus will make the water boil.
Remove the battery from the phone and connect the prepared wires to the corresponding contacts on it (plus and minus are labeled there), securing with tape. To avoid damaging the battery, we do not recommend charging the device to the maximum in this way. After 10-15 minutes, when there is enough energy for the desired call, text message or access to the Internet, it is better to disconnect the wires.
Charging using the frog
Suitable for: Those who have found an electrical goods store nearby
Dmitry Zaitsev /
What to do: “Frog” is a universal device for charging batteries, regardless of the type of connector. It will help if you are in the city with a dead phone and can’t find the right type of charger. This is a plastic box with a plug on one side and a clip on the other.
A simple and inexpensive device charges the batteries of smartphones and other gadgets, such as cameras. To recharge, insert the battery into the clamp, and plug the “frog” itself into a power outlet.
Homemade wireless charging
Suitable for: handymen who are too lazy to get to the store
majunxian /
If you have a wireless charging station and a phone that does not support this charging standard, you can upgrade.
You need a little free time, straight hands, glue, wire and a diode. So if you are the manager of an electrical goods warehouse or a physics teacher who has been kicked out of home and has to spend the night at school, try building a Do-It-Yourself charger.
What to do: Make a flat coil of thirty turns from the wire and stick it on the phone battery. Connect one end of the wire coming from the coil to the minus of the battery directly, and the other to the plus through a diode. Should earn; however, as a warehouse manager or teacher, you know better.
Charging from ground
Suitable for: avid tourists
This method is suitable if your phone runs out of charge during a long hike. In this case, you will probably have salt or soda, and metal objects such as a saw or tent pegs will be at hand.
What to do: Stick the pegs into the ground, wrap them with wire (preferably, in the classic way, copper) and pour a solution of soda or salt over them. Connect the free ends of the wire to the contacts of your battery. You won’t achieve a full charge, but you can revive your phone and let anyone know that you’re okay.
Scotch
Suitable for: Scotch tape suits everyone

As we said, tape is used to secure the wires during the charging process. But it can also be used as an independent remedy.
What to do: Place tape on the battery contacts and put the battery in place. If your phone isn't completely dead, this will give you a couple of extra minutes.
Battery heating
Suitable for: those who are not afraid to play with fire
Remember, the mouth of Orodruin is not the best place for your iPhone. Image: gizmodo
If the battery heats up even a little, it can briefly trigger chemical reactions inside the battery.
What to do: The most common heating method is with a knife: heat the blade over a fire, and then apply it to the phone battery. The main thing is not to overheat the battery and not to hold the knife on it for a long time, a few seconds will be enough. Otherwise, you risk losing the battery completely, and you might also set something on fire.
Shock charging
Suitable for: People with anger management problems
Maybe Brad Pitt's phone was just dead? John/
If you need to make one single call, and then the grass won’t grow and the phone won’t work, try this method. We warn you right away: the battery will probably become unusable after this.
What to do: Remove the battery from the phone and hit it hard against a rock or concrete slab. If you hit it successfully, the battery will receive a couple of percent charge. If you overdo it, you can throw away the battery right away. You can make a call using this battery only by hitting a passerby with it and taking away a normally charged phone. But we, of course, do not offer this.

lemon battery
Suitable for: freaks who turn even the lack of exercise into a show
Baca
This method, let’s say, is not the most adequate, because you will have to buy about a kilogram of lemons and some nails. The money spent on this can probably be given to the same fruit seller in exchange for the opportunity to call, but if you want something strange, make yourself a lemon battery.
What to do: Stick a nail into each lemon and connect the nails with copper wire, wrapping the heads tightly. Connect the ends of the wire to the battery terminals. With the help of such a “device” it is quite possible to make an LED light bulb glow, so it will certainly provide 3-5% of the battery charge.
Zaphod Beeblebrox from The Hitchhiker's Guide to the Galaxy had a helmet using similar technology. Instead of a battery in this case, his head was powered by lemons. Still from the film

From AA batteries
To the question of how to charge a battery from a phone without a phone, which we typed into a search engine, an interesting example came up using AA batteries. They are inserted into a special container that ensures sequential switching. To charge the battery, you need to connect the terminals of the device to the battery contacts, being sure to observe the polarity. How successfully the battery is charged depends on the capacity of the power cells.
The proposed circuit contains a 2 Ohm resistor, which allows you to reduce the voltage from six to five volts. But if the controller runs on a battery, then this is not necessary.
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 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. 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.
It is highly recommended not to perform any actions with the telephone battery that are not specified in the operating instructions. This may result in battery death, electric shock, short circuit or fire.
How to charge your phone battery directly
Potatoes and wires are not the only method of charging a battery. You can also “resurrect” your phone in various other ways that Internet users practice and share their experiences. The most common methods will be shown below.
Using a frog
A “frog” is a universal charger in the form of a plug with a compartment for the battery itself. It plugs into a power outlet and charges the battery with energy. This charger is also used to recharge batteries of cameras, tablets and other removable power supplies. The “frog” is sold at any electronics store.
To charge your phone using it, you need:
- Turn off the device completely and carefully remove the battery;
- Next, the user needs to find out which of the contacts on the block is responsible for the plus and which for the minus. If this is not determined correctly, then the device simply will not charge. Typically, all positive and negative connections are marked with + and – symbols on the power supply itself;
- Having determined the correct location of the connections, a person must open the cover of the universal charger and identify the terminals, which are also responsible for the location of the contacts only on the “frog”;
- Now you need to insert the battery into the “frog”, move the terminals apart and insert the contacts in the correct sequence: plus always goes to plus, and minus, respectively, to minus;
- You need to close the lid of the “frog”, fixing the position of the power supply;
- Then you need to connect the device to the network and wait for charging to finish.
You can determine that the unit is fully charged by the light on the charger. If the light is red, then the unit needs to stand still, but if it is green, then you can remove the battery.
Charging the battery from the adapter
The next fairly common method is to charge the battery from the adapter. This method is universal in that any power adapter will do, even if it comes from another device.
It is best to take an adapter from other devices such as a telephone. This can be either a regular tablet or an old phone. It is also worth giving preference to a 5V and 2A wire - these values are optimal for charging a smartphone.
To charge the battery using the adapter, you need:
- Having found the desired adapter, the plug is cut off and the wire is stripped. With correct manipulation, you should get 2 wires that determine the polarity;
- These two wires should be one with a plus and the other with a minus. They need to be connected to the battery in such a way that the positive wire is with the positive compartment on the battery, and the negative wire is connected to the negative;
- This design needs to be attached to batteries. The best option is to do this using regular tape;
- Next, you need to connect the adapter to the network and wait for charging.
Take precautions. The battery should not get too hot. If this happens, then the user took the adapter of the wrong power. It's worth changing the adapter.
Charge using a metal battery
This method can be classified as “emergency”, since it is not suitable for permanent use, and besides, it is extremely traumatic. You will need two metal tubes that are inserted into the ground. Next, they are connected to each other using any copper wire. From the same wire you need to create two contacts, which will subsequently be connected to the phone battery itself.
The salt solution will act as “fuel” to supply electricity. You need to mix it and then pour it over the wires that are stuck in the ground. The larger the metal parts, the greater the current will be.
This method will only help in emergency cases, when a small amount of energy is needed for the battery itself - for a maximum of one call. For long-term use, the metal battery method will not help.
Shock or heat
This technique may affect the future performance of the battery. Any actions that change the state of the battery may lead to its operational failure. As a result, it will have to be replaced completely, and this is quite an expensive undertaking.
Heating is a last resort measure that can only be taken in emergency situations. The maximum charge is enough for 1 call, so it is best to use other methods of charging your mobile phone.
The essence of the method is that you need to heat some metal object and apply it to the power supply.
Under no circumstances should the unit be allowed to overheat. This could cause an explosion. Be careful!
Hitting the block against a hard surface will also help recharge it for a while. The gap is small, so you should only use this method in emergency situations.
From AA batteries or powerbank
AA batteries or powerbanks are great helpers in restoring the battery power of any phone. This method will not help to fully charge the unit for a long time, but you can extend the work by 1-2 hours.
If the user does not have a power bank, then AA batteries are a good replacement. About 4 finger-type devices are needed, each of which is rated at 1.5 V. You will also need leads and a resistor with which the battery will be connected to the system.
An important feature of finger charging batteries or a power bank is accuracy. It is necessary to connect the terminals observing the laws of polarity. Do not forget also about the connection rule: plus always goes to plus, and minus to minus. Without this, you will not be able to charge the battery. To connect correctly, you need to focus on the figure:
As mentioned earlier, this method will not help to fully charge the battery, since the batteries will not have enough power. The power bank should be enough to fully charge the battery. The steps are almost identical: connect the leads and charge until full.
From another battery
The battery of one device can provide energy to another. Everything is quite simple if you know the law of polarity and how to connect the wires correctly. The steps are similar to the method of charging from batteries, only a unit from another phone will act as a battery.
Before connecting batteries, make sure that at least one of them has power.
You will need connecting cables and two batteries. Using tape, we connect the wires from one device to another. That's all! The main thing is to monitor the heating of the blocks and not allow it under any circumstances. If you allow it to heat up, there is a chance of breaking two devices at once.
Using clear tape
The method requires the presence of only two items: transparent stationery tape, as well as the battery itself with a low battery charge.
It is worth noting that this method is one of the safest. There are no terrible manipulations with the power supply that could lead to its damage. This is why this method is valuable. It will not give a full charge, since the battery will only last for one full-fledged call, but it will not fail after a while.
You need to take out the power supply, cover the contacts with tape, and then insert the unit back into the phone. A primitive method can bring the battery back to life for a while.
Solar charging
The main thing is to choose the right solar panels. They should be 6 or 4 W. If you take the power higher, the battery may overheat.
You can make solar panels yourself. All necessary devices can be purchased at any radio equipment store. This is enough to charge the device without difficulty. You can see how to do it correctly in this video.
The charging process should only occur during sunny times, since it is the energy of the sun that will power the unit.
It is enough to connect the batteries using special wiring and charge.
What effect do these methods have on your phone's battery?
Using the frog does not damage the battery. The device fully charges the battery without degrading its performance. Connecting AA batteries is safe, but unreliable. If the batteries are discharged, the procedure does not work. In addition, the method is difficult to implement. First you need to build a structure for batteries with leads.
If connected to an adapter, the battery may be damaged. The only way to safely revive a battery is with tape. Heat and deformation make the phone's power supply faulty. Experimenting with wires is suitable for old batteries.
Sometimes situations arise in which you need to charge the battery without the gadget in which it is installed. If such a problem arises for the first time, a person may encounter some difficulties. There are several ways to charge a battery directly, some of which may result in reduced capacity.
