Every once in a while I will notice significant decrease in battery life and when I go to about phone it's all coming from display. So I go to Settings and Brightness and it's cranked up to 75 or 80%. I always keep it around 25 to 30% with auto brightness unchecked. Why would my brightness settings reset themselves like this? I am rooted, running stock Froyo EB01, no ROM, LPP. Any help would be much appreciated.
