Your phone uses a rechargeable, non-removable battery. How long the battery can last before it needs recharging depends on how you use your phone. The features and accessories you use can affect battery life. For example, leaving your Bluetooth® connection always on uses more power. Long phone calls and frequent web browsing use up a lot of battery power. Also, consider your location: poor signal strength from your mobile network and extreme temperature make the battery work harder.

Charging the battery

Before you turn on and start using your phone, it is recommended that you charge the battery.
Important: Only the power adapter and USB cable provided in the box must be used to charge the battery.
  1. Insert the small end of the USB cable into the USB connector.
  2. Insert the other end of the USB cable into the power adapter.
  3. Plug in the power adapter to an electrical outlet to start charging the battery.
As the battery is being charged, the notification LED shows a solid red light. The light turns to solid green when the battery is fully charged.

When you charge the battery and the phone is on, the charging battery icon is displayed in the status bar. After the battery has been fully charged, the charging battery icon turns to a full battery icon .

Note: As a safety precaution, the battery may stop charging to avoid overheating.
