Generally speaking, there are three common repair methods for mobile phone lithium-ion batteries. The main reasons for repairing the lithium-ion battery of mobile phones are as follows: for example, the duration of each call is very short; For example, the cost of answering or dialing for about 10 times is dangerous, and so on. The purpose of maintenance is to prolong the service life of lithium-ion batteries.

The cycle life of mobile phone lithium-ion battery is about 600 times. Due to the repeated charging of the battery, the internal molecular arrangement microstructure is gradually destroyed, and the charging and storage efficiency is gradually reduced. In fact, maintenance of lithium-ion batteries is very necessary when long-term maintenance is not permanent.

1. Recharge and activate the battery after the short lithium-ion battery is fully discharged; This is to achieve deeper charging by using internal power supply, which requires some unconventional methods. When the battery voltage is lower than the rated voltage of 3.6 volts, recharging after discharge can last longer.

2. The mobile phone lithium-ion battery is packed in plastic and rested in the package as much as possible. There are three layers in total to ensure that the battery is in a vacuum state. Then, the food film is wrapped with three layers of newspaper. The lithium-ion battery is completely sealed. After 48 hours of freezing, the battery is taken out of the package and wrapped with six layers of paper film. The lithium-ion battery has no frozen surface caused by expansion and deformation. After cooling for a period of time, it can be recharged.

3. Use clean rubber or other cleaning tools to gently wipe the lithium ion battery and the metal contacts on the mobile phone to help the mobile phone battery charge and maintain its power.

The purpose of these processes is to easily destroy the internal structure of the original battery, which may add responsible capacity in a short time, but long-term use is not necessarily effective. Once the microstructure of the lithium-ion battery is damaged, it is impossible to completely recover. Long-term use of this method can accelerate the loss of mobile phone batteries.

Relevant experts pointed out that it is not feasible to take the maintenance method. Now the price of lithium-ion batteries is falling, why should they be repaired? The above methods are not necessarily effective, so it is the best choice to buy mobile phone rechargeable batteries.
