When I charged my battery, left and came back, the battery was full (100%) but after I went on the phone, the battery dropped to 95%, then to 90% and now 85%. I just charged it again and it says 90% again but can someone tell me why the battery level is dropping by a lot? I think it was because I overclocked my phone at 825mhz. Can someone also tell me a stable amount of mhz to set the phone to? <- (not sure if that made any sense)
