I. Mobile phone battery repair method When using eraser or other cleaning tools to wipe the metal contact on the lithium ion battery on mobile phone, so that it is conducive to the preservation of rapid charging and electricity. Repair Principle: After the mobile phone battery is used for a long time, its metal contact surface will have a certain degree of oxidation phenomenon, hindering better contact with the battery, wipe with eraser or other cleaning tools, the rusty substance Cleared, allows the phone to be better in contact with the battery.

Second, the first step in the mobile phone battery repair method first, first use the mobile phone battery to automatic shutdown state; second step, take the mobile phone battery, use the plastic film to wrap the three layers to ensure that the mobile phone battery is in a vacuum state In the third step, the mobile phone battery wrapped in the stocking film is wrapped in three layers to ensure that the mobile phone battery is completely sealed; the fourth step, put the packaged battery in the refrigerator, time is 48 hours; the fifth step After the freezing time arrives, take the battery out, remove its external wrap, and use the mobile phone battery to cool after a period of time. Repair Principle: The use of a mobile phone lithium-ion battery is actually a constant charging discharge process. In this process, the yin and yang charge in the battery constantly collides.

The performance decline in performance after a long period of use is because the internal kinetic energy of the battery is large, and the leakage is relatively frequent; and the battery is placed in a low temperature environment, which will cause the lithium ion battery surface The microstructure of the lithium film, the electrolyte, has a degree of change in the interface, so that the inside of the battery is detached from the active state, and the leakage phenomenon is reduced. Therefore, put the lithium ion battery low temperature after a while for a period of time, and its standby time and other performance will be clearly improved. Third, the mobile phone battery repair method three uses a specific device to connect the phone with the low voltage bulb, the internal power of the battery is transferred to the bulb to achieve the depth discharge of the mobile phone, and the battery battery after the depth discharge can be charged again.
