Charging the battery

Your phone battery is partly charged when you buy the phone. It may take a few minutes

before the battery icon

appears on the screen when you connect the phone charger

cable to a power source, such as a USB port or a phone charger. You can still use your phone while it is charging. Charging the phone over a long period of time, for example, overnight, does not damage the battery or the phone.

The battery will start to discharge a little after it is fully charged and then it charges again after a certain time when the phone charger is connected. This is to extend battery life and may result in the charge status showing a level below 100 percent.
