Your phone uses a rechargeable battery. Please use only original batteries and accessories that came with your phone or replacements that we recommend.

How long the battery can last before it needs recharging depends on how you use your phone. Among these are the phone features and accessories you use (for example, leaving your Bluetooth connection always on uses more power). Long phone calls and frequent web browsing uses 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.

Removing the battery

Important: Right after you take your phone out from the box for the first time, don’t forget to remove the thin film wrapped around the battery that’s inside your phone.
  1. Take the back cover off.
  2. Lift the battery from the groove at the top of the battery compartment.
  3. Pull the battery out of the battery compartment.

Inserting the battery

  1. Take the back cover off.
  2. Insert the battery (with its exposed copper contacts first) into the battery compartment.
  3. Replace the back cover.

Charging the battery

The battery is partially charged when shipped. Before you turn on and start using your phone, it is recommended that you charge the battery. Some batteries perform best after several full charge/discharge cycles.
  • When the phone is shipped, the battery is already installed on your phone. A thin film is inserted between the battery and the compartment. You need to remove this film before you can charge the battery.
  • Only the power adapter and USB sync cable provided with your phone must be used to charge the battery.
  • Do not remove the battery from the phone while you are charging it using the power or car adapter.
  1. Plug the power adapter into the USB connector of your phone.
  2. 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 phone is fully charged.

When you charge the battery while the phone is on, the charging battery icon is displayed in your phone’s 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 stops charging when it overheats.
