Hey guys, I am wondering if there are any methods to save battery life on my Sony Ericsson Xperia ARC? Here are the details of my settings: Screen timeout - 30 seconds Brightness - 25% WiFi - Off GPS - Off Bluetooth - Off Syncronisation - Off Background data - On. Also, do the battery saver apps actually work? Because I've read a few places that they don't help at all? Thanks.
