Common problems and solutions for mobile phone battery charging

Common reasons and solutions for charging mobile phone batteries. Mobile phone batteries in contact with oxidation and corrosion will increase impedance. Long-term used battery devices are inside the mobile phone. The humidity (such as sweaty water vapor) in contact with the human body is very high, resulting in simple oxidation of the battery contact. Rusty. There is a long-term current-limiting resistance between the battery and the motherboard. This also makes the charging current scarce and difficult to charge. Solution: Remove the battery, contact the battery, use a cotton swab or pencil tip on clean toilet paper (use 0# sandpaper to cut into small pieces if possible), wash each time after electric shock, until the contacts touch the bare cheeky, if oxidized Objects are difficult to remove, you can use a needle or point one by one, but be careful, otherwise you can not touch two contacts at the same time, otherwise the blasting may short-circuit; finally, the battery is restored. Try to charge. The current in the charger is insufficient or the charger itself is damaged. For example, if your mobile phone has a battery capacity of 2000 mA (2000 mA), and long-term use of a charger with an output current of less than 2000 mA, the battery may not be fully charged. This is because the current is the charger impedance. When it is added, this approach uses less energy to charge the battery. Solution: Check whether the current indicated by the power output on the charger shell (usually a plug) is lower than the battery capacity. If yes, please replace a qualified charger. Many netizens have this habit of charging these three mobile phones directly from the front USB port of the computer. When they are online, they will charge the charging cable of the mobile phone and the front USB port of the computer. Although it is convenient, I don't know that the power distribution of early computers was lacking. The motherboard would output to the front panel of the case. The power of the USB power supply is limited (for example, the maximum output current is 800mA). The phone seems to be charging normally, but the charging current is insufficient for practice. The charging time may be 10 times longer than usual, so it always feels like it cannot be charged or the display is full. However, once you leave the charger, the power supply will be reduced. Solution: Insert the USB charging cable into the back of the case and connect it directly to the USB port of the motherboard (usually there is no output current limit for USB) or use the original charger for charging. If you use the above cleaning method, the battery charger is still not fully charged, which is mainly caused by the battery itself. It is recommended to send the mobile phone to the relevant service provider for sale.
