my battery life has been suffering for a while which is why i only oc to 800mhz. the weird thing is that it'll go from 80% to 40% when i'm sleeping. everything is turned off except for the sync. the brightness is at the minimum, and i have everything at silent. i woke up and got on the internet and went to 2 pages (no flash) and the battery went down to 20% is anybody else havin this problem because i'm really not tryin to buy a new battery especially for a phone i'm not gonna have for another 3 or 4 months
