12 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.
Removing the battery
When you take your phone out from the box, make sure to peel off the thin film of the battery
that’s inside your phone. Pull the flap of the film to release the battery.
1. Take the back cover off. See “Back cover” for details.
2. Lift the battery from the groove at the top of the battery compartment.
Inserting the battery
1. Take the back cover off. See “Back cover” for details.
2. Insert the battery (with its exposed copper contacts first) into the battery
compartment.
3. Replace the back cover.
