Phone battery has turned to crap for no reason?
I just got this phone 2 months ago and lately for no reason it has been draining like crazy. I had got it to start lasting for 36 hours at some points before the battery got low and now out of no where its started only lasting like 8 hours. I haven't been using my phone anymore so I don't know what the problem is. Take last night for example. I charged the battery till it was FULL and pulled it off the charger at maybe 1 am. I used it to text a couple times and talked on it for like 2 mins and went to bed sometime around 5. I woke up at 3:30 and it's dead. This might be acceptable had I been using it but the thing has been completely idle for the last 10.5 hours! How could the battery be draining so fast? Especially when it wasn't before? Is my battery broken somehow?
EDIT: Also I'm even using SETcpu to clock my phone down to 600 MHz when I'm not using it (aka screens off).
