Guide: Mobile phones are becoming more and more important in our life. It brings us a lot of convenience and adds a lot of fun to our life. As we all know, batteries are a very important part of mobile phones. Mobile phones need batteries to run, but there will be some problems after the battery has been used for a long time. Do you know how to repair the lithium battery of mobile phones in daily life? Let's take a look at how to repair the lithium battery in our daily life.

Repair method of mobile phone lithium battery:

1. Use a clean eraser or other cleaning tools to gently wipe the metal contacts on the lithium battery and the metal contacts on the mobile phone, which is helpful for the charging condition and the durability of the power.

2. The lithium battery of the old mobile phone that uses automatic shutdown shall be tightly wrapped with plastic wrap, which shall be as snug as possible, with three layers inside and outside to ensure that the battery is in a vacuum state. Then, wrap three layers of newspaper outside the plastic film to completely seal the lithium battery. Put it into the freezer layer of the refrigerator. After 48 hours, take out the battery and remove the six layers of paper film wrapped outside one by one. The lithium battery has no surface expansion or deformation due to freezing. After cooling for a period of time, then charge.

3. Let the nearly discarded lithium battery completely discharge, and then recharge and activate the battery. The specific method is to conduct deep discharge on the mobile phone, which is to achieve deeper recharging by exhausting the internal electric energy. This requires some unconventional methods. Use a specific device to connect the cell phone to a low voltage small bulb, and the power inside the battery will be transferred to the small bulb until all the lights come out. "The mobile phone needs to slowly use up its power through a lower voltage. Under normal circumstances, if the rated voltage of the mobile phone is lower than 3.6 V after it is connected, it will automatically shut down." After the battery is discharged, the recharged mobile phone battery can be used for a longer time.

The cycle life of lithium battery is about 600 times. If the number of charges increases, the thermal movement of molecules will gradually destroy the internal molecular arrangement microstructure, and the charge storage efficiency will gradually decrease. "The freezing process is easy to damage the original internal structure of the battery, which may increase the ability to charge in a short time, but it is not effective for long-term use." Professor Ye said that once the microstructure of the lithium battery is damaged, it is impossible to completely recover, and long-term use of this method will accelerate the loss of the cell phone battery.

The above is the repair method of mobile phone lithium battery. If you also want to make your mobile phone battery have a longer life, let's quickly learn about the repair method of mobile phone lithium battery. I believe that through the above introduction, we can repair the battery to a certain extent. In addition, we should also pay attention to the use of mobile phone battery in our daily life, and only form good habits, In order to make the battery life of the mobile phone longer, let's quickly learn about the repair methods of the lithium battery of the mobile phone.
