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.
