Over the last 6 weeks or so I've noticed a dramatic drop in my phone's battery life. I've had it a year and used to quite happily listen to a bit of music, send a few texts etc during the day and get home with around 60% battery left. Today ( which has been typical of the last few weeks ) I've sent one text had no calls, not used internet or music and come home with 25% battery. It's also taken to occasionaly locking so I have to remove the battery to reset and gets very hot. The only significant new app I've put on has been DH3 which I've now taken off just in case. The battery is charged overnight, I have noticed a couple of times it's only been on 90-95% power in the morning. Phone info says Cell standby has used 70% of the power, the OS 20%, display 4. Firmware version is 2.3.3, gingerbread.xxjvo GPS is always turned off, Wifi and data network turned on only when I use them. Background data off unless I'm accessing the apps store. Running applications reports nothing out of the ordinary. I've tried power cycling it to no effect. Any guesses what's up? As I'm still on contract should I be taking back and shouting a lot? As it is it's barely adequate as I'm likely to run out of battery before I get home on some days. I'm tempted to insure it then hit it with a brick if I can't solve the problem.
