All smartphones are programmed to stop charging the battery once fully charged. At that time, the phone runs solely off of the charger’s electricity while still plugged-in. Therefore, there is no risk of overcharging the battery when you leave a smartphone charging overnight.

However, since every rechargeable battery can only go through this cycle a limited number of times, it is possible to charge your phone too often. For optimum performance, charge your battery once it gets down to about 10 percent. Then, charge the device until it’s up to 100 percent.
