I always charge my phone at night, and naturally when i wake up it is at 100%, but lately after i unplug it, jsut 5 minutes later the battery launches back down to usually in the 20%'s. I dont have an app killer, and i deleted android assistant, i dont know if that was teh problem, adn i also have a battery widget that is displaying my percents that im using, which is also relative to teh battery displayed in the top taskbar. please help!
