I did a quick search of the forums and found the OS 3.1 "coma" issue, but not this battery-drain issue, so I would really appreciate any help from you guys! I have a new 3GS, 16GB, updated to OS 3.1. For the past few days (seemingly all of a sudden), my battery drain has been QUICK. It drops maybe 8% every hour, even in standby. - I don't use it for music. - It doesn't seem like any of my applications would be running without my knowing. - I turned off Bluetooth, Wifi, and Notifications. (but I still have 3G on, always have without problem). - The screen goes off as it should after no activity. But still, for some reason, just in the past couple days, it's been draining quickly. I thought about any new apps I downloaded, but I can't see any problems there. Is this a 3.1 issue? I thought it was supposed to increase battery life? Do any programs have issues running in the background? Thanks for the help!
