Title pretty much says it all. I have a stock, i777 running on 2.3.6 and yesterday out of the blue, the phone would lock up (not respond to any touches on the screen, the power button or the volume rocker) so I would pull the battery out and restart it. When I did, the battery would drop off like 15%. I did a search but didn't find any relevant issues. Many people simply complained about battery drops after regular restarts, not after freezes. Would greatly appreciate some help!
