Is the mobile phone battery overcharged?
For the problem that the mobile phone battery should not be refilled after it is full, there are different opinions. Most netizens suggest that it is best to continue charging for 2-4 hours after the battery is full. But is this advice right?
Some people on the Internet said that they have used three batteries to conduct experiments using different charging methods. The results show that it is good to have more batteries after the battery is fully charged. In this regard, an engineer named Liu, a Samsung mobile phone repair center in Beijing, said that there is no basis for replenishing an hour. It is completely wrong for a mobile phone industry executive in Shenzhen to say that it should continue to charge for a few hours after the battery is full. There is a chip protection in the mobile phone, and it will not work when it is full. It also means that the lithium-ion battery is full of refilling, although it will not explode, but it will speed up the loss of battery capacity. Zhang Xiaodong, director of the Science and Technology Information Center of Jiangsu Sai Lian Information Industry Research Institute, said that any form of overcharge of lithium-ion batteries will cause serious damage to battery performance. In serious cases, even explosions, it is necessary to avoid overcharging the battery during charging. .
There is no unified statement about whether the mobile phone battery should be refilled after it is full. However, for safety reasons, it is best to just fill it up to avoid battery damage or explosion.
