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.
