According to Gao Peng, the current mobile phone batteries are all lithium batteries, while the previous ones were mainly nickel-chromium and nickel-metal hydride. "The current battery does not have memory. It does not need to be continuously charged for 12 hours when it is first used. It is best to keep charging during use. Don't wait until it is completely recharged." Gao Peng said that the original charger of the general mobile phone is It has a charging protection function, that is, the phone will automatically cut off when it is fully charged, but the universal charger and the charger do not basically have the function of charging protection.

"After the battery has reached a certain useful life, sometimes the charging will bulge, indicating that it is full of gas, there is a danger of explosion." Gao said that the performance of the current lithium battery is superior to the old battery, using Try to use direct charge and charge, and strictly control the charging time of the phone.
