What will harm your phone's battery while charging?

Your phone is smart enough to not to take damage by overcharging, but you need to pay attention to the following threats that probably harm your phone’s battery.

Heat

You’ve probably noticed that when you charge your phone for a few hours, your phone, as well as the charger, becomes very hot. That’s because a lithium-ion battery warms up as it charges; as it gets warmer, it charges faster. Charging a phone causes heat, which is a silent killer to a lithium-ion battery.
