    So I usually keep my UMBP plugged in at all times.
    It unplugged by accident and went to 99% so I left it unplugged but literally less then maybe 7 minutes my battery is already reading down to 92%. brightness on screen is set all the way up, if that has anything to do with it.

    Is this normal?

    No idea. Depends on what your computer was doing at the time it was unplugged. If you're like 98% of the other "battery thread" posters here, your battery is fine.
