My S2 died completely a couple of weeks ago and went into a shop for repair (under warranty). They said it was the battery (which suprises me because when I took the phone in the guy put the batter from his S2 into it and it still wouldn't turn on) and say they have replaced it.
However, I used to get 1.5-2 days useage on a charge but now get around 10hrs maximum. Over night last night when on standby my battery went from 100p/c to 49p/c.
Is this normal?!
