Hello all, hoping someone can help me! For about a week now, since updating my firmware, I've been having some MAJOR battery problems with my S2. Up until last week I could normally get 12 hours battery use from my phone without having to charge in between, and with normal to moderate use. Now, I am lucky if my battery lasts an hour tops, without me using for more then messages. The battery indicator will still show about 80% power, but without warning the phone will turn off. No "battery low" warning or vibrations, just off. When I turn the phone on again it shows straight away the phone"battery critically low" warning, despite it being over 80% before the power out. I can leave it 'alone' for over an hour, but it still shows the warning and turns off. When I put it on the charger again though, it shows once again the battery icon as being over three quarters full.. This is NOT normal. I am a freelance worker, therefore I need a phone that I can use to communicate with clients throughout the day, as well as checking emails and what not. Up until last week my S2 was that perfect phone, but now, lasting less then an hour , it is holding my work back. Any help would be lovely, I still have a year on this contract, and cannot afford to have a phone that doesn't work.
