Hi, this is a partial re-post from another thread as i didnt want to hijack the original thread....Any suggestions on this would be much appreciated..... I recently exchanged my GS2 for another GS2 with my provider as my battery was lasting only around 7-8 hours, with virtually no usage and widgets etc turned off. My repalcement hand set has been much better (approx 24 hours of light to moderate use) until yesterday. Now I seem to be getting power drain from WiFi sharing, even though i have WiFi turned off, and havent ever used WiFi sharing (I have used regular WiFi just for a connection - but not today). Today my battery has gone from 100% to 20% in just over 5 hours. Ive hardly used it (one 2 min call, a twitter update & push mail on). Its lasted much longer than this before. My battery usage app (default one) says Wi Fi sharing is 26% but ive had Wi Fi off all day.... I dont understand why this has started happening and why its eating so much power. Social Hub is also 26% which seems much higher than usual, I havent sent any email and have had only a few small message pushed to me. Any thoughts on how any of this could happen? Any suggestions from anyone would be much appreciated.
