    Ok. So I've had this 820 for the past 8 months. But then recently (2 days ago) the battery went nuts. I'm losing 2% every 5 minutes, opposed to 2% every hour.

    I'm on amber.

    The things that have happened in between my phone being normal and it going nuts were:
    Facebook Beta was updated (uninstalled)
    Hardware Tests was updated (uninstalled)
    Sys app Pusher was updated
    The three above probably didn't cause it

    Next two:
    My plan was cancelled: I'm a bit behind on payments on it... So could it be randomly trying to search for signal?
    I removed my micro sd card and put it into my computer to view the files inside before returning it into my phone... (I did all this before turning on the phone again. However, I did not safely eject the sd card from the phone so there may have been some problems?)

    Whatever the issue, my phone has not been hot such as times when gaming. However, it has always been slightly warmer to the touch than before it had this issue. The heat issue is fixed when I go into airplane mode.

    Any help is appreciated. Thank you.

    Hi, Can you please check if your connection is 3g/4g and when there is no enough signal, it falls back to EDGE (2g) and at this point it search hard to swicth back to 3g/4g so it drains battery quick and also generate lot of heat. Also keep wifi disabled when u dont want or use them.

    When your phone get heat and drains quickly, turn ur phone off for a while and turn on, this happens to me sometimes and it always works...

    Hope this helps...

    You need sometimes to restart the phone to refresh the system.

    Turning off did not help
    putting it into airplane mode made me get 1% battery drain per 2 hours
    I do not turn data on...

    I occasionally get super battery drain (battery drains from 100% to 5% or dead within 2-3 hours) its really strange coz otherwise i always get good battery back up which last around 1 day. I use 2g when im out and wifi at home and its on amber as well. Just recently when i realised the battery was draining faster than usual (5% every 2-3 min) i restarted my phone and everything was back to normal. Weird issue though its quite rare

    You must sometimes restart the phone to refresh the system and prevent battery drain fast.
