    Battery Behaving Strangely

    Hi All,

    I had bought a tab 2 7.0 a month back. From past 2 weeks my tab battery is behaving strange. After fully charging (100%). The battery keeps discharging and again battery charge increases without charging. Like its display's message for low battery(1%) and after some time I see the increase in battery %, 25%..30% 28%...35% ..... its keeps increasing and then decreasing. Finally drains out after 2 days....
    Guys please help me out...

    Thanks in advance
    Sandy

    re: Battery Behaving Strangely

    Drains out? Are you letting it fully drain before charging?
    It sounds like your battery meter is out of calibration with your battery.
    Let the Tab get down to about 5% or so, charge it fully while off. Post back if that doesn't work.

    Yes if it's practical. If the attempts you did didn't work it sounds like more than a simple battery calibration problem.

    I also have this problem. To clarify, with the device on, the battery level INCREASES. Once it hits 100%, it drops to 1% (screen dims, it gives critical warning) and then the level again starts to slowly rise. Once it rises above the "critical low level" it undims the screen.

    Given this, there is no way to tell what the actual battery level is. I am trying to completely kill mine by letting this cycle repeat until it dies, to attempt the "let it fully drain" idea.

    Check out this screenshot of my battery history for the last day:



    I would love to hear about a solution to this problem. If not, I'll simply have to return it. (and it was a Costco purchase, and they don't have any more)

    Device
    Other Android Tab
    I would do a cold bootnand see if that resets the battery. Then charge the tab for a full 8 hours
