Introduce some mobile phone battery repair methods

1. Mobile phone battery repair method 1: Use an eraser or other cleaning tools to wipe the metal contacts on the mobile phone and the mobile phone's lithium-ion battery. This is conducive to fast charging and power preservation. 2: Repair principle: After a long time use of the mobile phone battery, the surface of its metal contacts will be oxidized to a certain extent, which prevents better contact between the mobile phone and the battery. After wiping with an eraser or other cleaning tools, the surface of The rust is removed, so that the phone and the battery can be in contact with each other better. 2. Mobile phone battery repair method 2: The first step is to use the mobile phone battery to the automatic shutdown state; the second step is to remove the mobile phone battery and wrap it tightly in three layers with plastic wrap to ensure that the mobile phone battery is in Vacuum state; The third step is to wrap the cell phone battery wrapped in plastic wrap with newspaper for three layers to ensure that the cell phone battery is completely sealed; the fourth step, put the wrapped battery in the refrigerator for freezing, the time is 48 hours; Five steps, after the freezing time is up, take out the battery, remove its external wrapping, and charge the battery after cooling for a period of time. 2: Repair principle: The use of mobile phone lithium-ion battery is actually a continuous charging and discharging process, in this process, the positive and negative charges in the battery are constantly colliding. The reason why the performance of the battery will decrease after long-term use is because the internal kinetic energy of the battery is large and it is always active, and the leakage phenomenon is relatively frequent; and putting the battery in a low-temperature environment will cause the surface of the lithium-ion battery The microstructure of the lithium film, the electrolyte, and the interface have changed to some extent, which makes the interior of the battery out of the active state, and the leakage phenomenon is reduced. Therefore, if the mobile phone lithium-ion battery is placed at a low temperature for a period of time before use, its standby time and other performance will be significantly improved. 3. Mobile phone battery repair method 3: Use a specific device to connect the mobile phone to the low-voltage bulb, and all the internal electric energy of the battery is transmitted to the bulb to realize the deep discharge of the mobile phone. The deeply discharged mobile phone battery can be recharged and used again. Longer standby time. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
