14 Basics
Battery
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 use up much battery. Also, consider your location:
poor signal strength from your mobile network and extreme temperature make the
battery work harder.
When you take your phone out from the box and remove the back cover for the first time,
you’ll find that the battery is already installed with a thin film. Pull the flap of the film to release
the battery. Make sure to remove the film before you insert back the battery.
Removing the battery
1. Take the back cover off.
See “Removing the back cover.”
2. Lift the battery from the groove at the top of the battery compartment.
