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.
The battery will start to discharge a little after it is fully charged and then 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.
