I took the phone off charge a day and a half ago and it still has 36% battery left with 2h 40m screen on. Only one very short phone call but loads of emails and texts and a couple of short YouTube videos (maybe fifteen minutes total). I don't game on the phone at all. This is far above what I expected from this phone and really urinates all over my iPhone 5 battery life. Absolutely amazing battery life for me!
