A common problems and solutions of mobile phone battery

Source: 2020 - 03 - 24 13:04 hits: common causes and solutions of mobile phone battery contact with oxidation corrosion of long-term use of mobile phone battery can increase the impedance device inside the cell phone batteries, and human exposure to moisture ( Such as sweat water vapor) Simple is very high, which leads to the battery contact oxidation rust. Between the battery and motherboard produce long current limiting resistor. It also makes the charging current is scarce, difficult to recharge. Solution: remove the battery, battery contact, use on the clean toilet paper cotton swabs or pencil tip ( Conditional can use 0 # emery paper cut into small pieces) Touch the point contact and get an electric shock every time cleaning, until the bare cheeky, if oxide is difficult to remove, can use a needle or pointed out one by one, but should pay attention to, otherwise can't contact two contacts at the same time, otherwise blasting may be short circuit; At last, the battery back. Try to recharge. The inside of the charger current shortage or the charger itself, for example, if your phone battery capacity of 2000 milliampere ( 2000 ma) , long-term use of output current is less than 2000 milliampere chargers, batteries may not be able to fully charged. This is because the current is the charger impedance. When it is added, it use less energy to recharge the battery. Solution: check the charger shell ( Usually the plug) On the output power of the indicated whether current is lower than the battery capacity. If yes, please replace the charger. The three phones directly from the computer's USB charging before many netizens have this habit. When they get to the Internet, they will give mobile phone before charging line and computer USB charging. Although convenient, but I don't know the early computer is lack of power distribution, main board will be output to the chassis front panel. USB power supply power is limited, For example, the maximum output current is 800 ma) 。 Recharge my mobile phone seems to be normal, but the practice of charging current. Charging time may be 10 times longer than usual, so always feel unable to charge or display is full. However, once left the charger, power supply should be reduced. Solution: insert the USB charging line on the back of the case, directly to the USB port to connect to the motherboard ( After the general USB no output current limit) Or use the original charger. If the cleaning method used above, the battery charger is still not full, is mainly caused by the battery itself. Proposed to mobile phone to the related service providers for sale.
