    So, I've owned my Surface since launch day. I love it, and have no regrets.

    I just recently started having an issue where the battery seems to be draining quite quickly under basic web surfing, etc.

    I just lost about 10% in about 10 minutes of surfing. 1% a minute? Before, I'd maybe lose about 1% in 10 minutes.


    How can I find out what is running that is draining the battery? I have installed an SDCard recently....could that be it? I've also been installing a lot of different apps too.

    Thanks for the help!

    Can't quite call it. Background apps that run all the time might be the first place to look.

    Charm bar, search, task manager. Run that and look at detailed view. See what is taking high CPU.

    If thats doesnt shed light on the App, you can try this:
    Guided Help: Get a detailed Power Efficiency Diagnostics Report for your computer in Windows 7

    It works on the Surface. Likely you will see a warning about an App or piece of hardware malfunctioning

    what johninsj said, did you try rebooting the tablet? this will kill any open apps that are bugged and killing the battery.. if after the reboot it's fine, then you can track down the issue.

    my surface has AMAZING battery life.. i can get 2 days of minimal use before needing to charge. Last night my surface was at 30% battery and i pulled it out and used it for 3ish hours with xbox music and another open app for a game i was playing with my friends. the screen wasn't turned off at all either for those 3 hours. battery was at 4% when we were done. That is some pretty heavy use i'd say.

    I was having similar problems and my battery died a few days ago. Sent it in for the warranty. Not saying your battery is bad but that could be the problem.
