mines the same except power v48+a scud battery and i'm getting some really good results since i re-installed yesterday afternoon since 17.30 last night when it came off charge i am down to 79% only been texting and updates though.

i've also changed overclock max to 600 as i found a reflash and the latest cssu improves it a great deal

24 hoursish later 76%. light use (text messages)
