1. The new battery requires several full charge - discharge cycle to activate
In fact, today's smartphones don't need this because the smartphone batteries on the market are mostly lithium-ion batteries. The initialization process has been completed during the manufacturing process, so no activation is required when in use.
2. Reduce the number of charging to extend battery life
In fact, pay attention to the lithium battery "eat more", frequent shallow charge and discharge will help to extend its life! Remember to "eat more", don't pull the phone for a long time, this will speed up the battery capacity loss rate.
3. Overcharging can cause the battery to explode
In the same theory, lithium batteries generally have safety protection circuits and various safety devices to ensure excessive charge and discharge and short circuit when the battery automatically cuts off the circuit. Unless there is a quality problem, the battery will not charge and explode for a long time.
