Okay, well I know battery sucks, but I have thought about it. The battery lasts me well over 3-4 days when it is just off... and when I use it A LOT it gets me through the day with a bit more than 35%. And when I say a LOT I mean watching a couple videos, listening to about 2 hours of music (while screen is off) and playing games like Asphault. It charges VERY quickly (although I do not use the Samsung one) and I just feel that the battery life doesn't do what it is stated, but if it lasts me through the day, then I'm fine because I charge it everyday ANYWAYS! Just my 2 cents
