How to Repair your mobile phone's Lithium Battery 1 Use a clean rubber or other material cleaning tool to gently clean the metal material contacts on top of the lithium ion and mobile metal contacts, which is good for battery charging and long-term power engineering.

　　1, there is a simple maintenance method, there is a way to eliminate lithium ion electricity. If left for a week, it will gradually drain power. Equipment must be used before it is completely consumed. Then fully charge, keeping in mind that your battery charge time is undoubtedly short. After being fully charged, the power must be reasonably cut off again and continued several times.

　　2. The old phone's lithium battery and automatic switch will be tightly wrapped in a new bag. When the packaging is as close as possible, the top and bottom are divided into three layers to ensure that the rechargeable battery is in the vacuum pump condition. Then, three layers of newspaper are placed on top of the toast in a plastic bag to completely seal the lithium battery. After placing it in the cold layer of the refrigerator, remove the rechargeable battery after two days and remove six layers of paper film from the bag at once. Lithium ions do not bulge or deform in response to cold. After a period of cooling, the battery is charged.

　　3. Let the lithium-ion battery near the charge fully charge and discharge, then charge it again. The specific approach is: the deep charge and discharge of the mobile phone is based on the external electromagnetic energy consumption to achieve deep charging, must choose some unconventional ways
