My phone will go from like 8am to noon and have like 70% left..today while at the movies in a strong signal area I had it in my pocket and it felt hot the whole 3 hrs of the movie and i knew something was working not sure what and when I got out it went from 95% to 40% and this is what the battery said. I've been running JB for a while now but never any day has my battery became a cookie! I just restared and installed better battery stats to have something to measure what it is if it ever does it again
