I have the original note,I was happy with the battery life and now all of a sudden it started discharging at the speed of the light, at least it seems to me! :-( What I'm talking about is that with my phone sleeping, my battery discharge s to 50 in 3 hours. I tried to figure out if I changed my settings lately or introduced apps that could cause this, but I didn't. Idon't remember my screen light being so bright when I put it all the way down,I have the feeling that my light got stuck or I really don't know what to think about. !
