What are the ways to restore a mobile phone battery?

The phone battery is a key element of a mobile phone, without which it stops working. It is thanks to the battery that the phone is called mobile. At the same time, the battery is the weakest place of smartphones. which are installed in modern phones, serve 2─4 years. Their resource is 400─500 cycles charge shade. The smartphone on which is constantly going to the network play, watch video, requires charging almost every day. As a result, the battery life is significantly reduced. In a year, the battery can lose up to 15─20% of its nominal container. This material provides several tips on how to restore the phone battery.

The procedure is to replace the battery bank to a new one. This requires the purchase of a similar bank, the process will turn into full repair of the battery. Such things make sense to do if you need a battery for an outdated phone model. Otherwise, it's easier to buy a new battery.

This article will consider ways to restore the phone acb for a short period.

How can I "push" the phone's battery?

If the battery lacked for a long time, it can be restored in this way. Some miracle should not be expected here, but the method will help restore the battery to such a level so that it can turn on the phone. Why can this come in handy? For example, you changed the phone, and old abandoned. The battery voltage fell below the permissible limit, and the controller has blocked it. And the contacts and valuable photos remained in memory. In order not to buy a new acb, you can use this method to turn on the smartphone.

What might need?

• Power supply from the modem, router, other phone, tablet. At the outlet, it must provide voltage from 6 to 12 volts;
• Copper, wires, clips, soldering iron, tape;
• Street resistor. Power must be at least 0.5 watts;
• Multimeter. To measure current and voltage.

What do we have to do?

• Using wires, output plus and minus from the power supply connector. To do this, clean the overall, one insert into the connector (plus), and the second attach to the outer part (minus). And the wires will fasten them with a tape;
• Other wiring ends Connect the battery banks to the conclusions. To do this, it will be necessary to disassemble and connect to the plus and minus banks already behind the controller. You can make it with the clamps of the appropriate size or by soldering;
• A stroke resistor is installed in the plus wire break.

To begin with, put the current about 50 mA. To do this, you need to calculate resistance. To do this, use the Ohm's Law. The resistance is calculated by the formula R \u003d U / I. If the power adapter that you use has 12 volts, then R will be 12/05. This gives 240 ohm. You need to include such a resistor with such resistance or trickening. The latter is much more convenient because it allows you to change the value "on the fly".

After assembly, the power adapter is activated in the outlet. After certain time intervals, measure the voltage at the outputs. It should gradually increase. Ideally, you need to bring the voltage to the value close to the rated battery. If the process goes too slowly, try to increase the current strength by reducing the resistance. But be careful, follow the battery temperature and its condition. If the battery warmed up or swollen, turn off the power supply from the network immediately.

Do not leave the battery on charging unattended. The bank is charged directly, and therefore the controller will not stop the process automatically. Lithium batteries can not overheat. This is fraught with fire. It is better to charge the battery to some level and try to set the phone. If the controller turns on the battery, then the remaining charging process is better in the phone.

"Push up" the battery can try the automotive battery. Connect minus contacts banks and car batteries and positive wire to the telephone battery. Then the other end of the plus wire is quickly touched by the positive output of the automotive battery. At the same time, it may even be sought.

Touch must be done quickly so that the wire does not shine. After 3 compound touches, measure the battery voltage. Procedure do as long as the voltage does not stop growing. After that, continue charging the phone.

Using cold to restore AKB

Quite often, this method is found on the forums as a recommendation for recovering the phone battery. But apparently, we are talking about alkaline Ni─cd and ni─mh batteries. The fact is that dendrites are formed in such batteries during operation. It turns out that part of the active elements in the electrodes are excluded from the process. The battery capacity drops. In such a situation, this method can help restore the battery.

As a result of cooling in the refrigerator, dendrites become fragile. The subsequent lung impact effect or shaking destroys them. Thus, it is possible to partially restore the lost container of the alkaline battery. But we are talking about alkaline batteries. For lithium-type telephone batteries, such a procedure may not only be useless, but also harmful.
