I just bought a new galaxy S3 from T-mobile. And i think, the battery run out quite fast. To be honest guys, this is the first time i got a phone as new as this one. Before this phone i had 2 really old phone that was used by my sister. So with those phone the battery ran out extremely fast, it was really old (2-3 years old), so it is understandable. But with this Galaxy S3, even though the battery does not run out as fast as those old phone but i expected more than that. I turned of everything i could, lowest brightness, close every "stand-by" apps, clear memory, log off of email, Wifi off while the screen is locked. And i still lose battery even when the screen is locked! why ? My ipad and ipod does not. I surfed the internet with 4G and i lose 14% battery in 30mins !? On average, i lose 1% of battery per 3mins while i surf internet with 4G. 100% before i went to sleep, after 7hrs of sleep, it loss 8% :/ I only have 3 apps: Yahoo, Facebook and Chrome. Is this normal ?
