You just got me to call up T-Mobile. I don't have an S4 right now, but rater the MyTouch Q, and I have some crappy battery life. I've gotten two replacement batteries (not from T-Mobile) and they haven't been any better. So their customer service suggested sending out a new phone instead of a new battery because sometimes it's the phone that is causing the problem. So we will try that out first and then if it still isn't any better, then we'll look into a new battery from them.
Any upgrade in the near future Smalls? Rather than messing around with an older phone might just be easier to get a newer device. It is amazing how fast the technology changes and improves. Also check out Swappa.com you can get used devices there for much cheaper than retail.
