i got 8 plus hours on my TB today.. played a bunch of Ninja Rush... Some browsing.. some phones calls.. on 4g All day...
im coming from an INC.. I can easily get 8hrs off a single charge.. while being on 4g all day... depends on how much you use it.. cycle the battery a few times.. it will improve.... i do play with the brightness too.. i dont have it at full brightness ever.. that too bright anyway... if its dark.. i turn off brightness.. or have it at about 20%..
i do not have any pop email, no facebook, no twitter.. just gmail, calls, txt, games, browsing..
