More recently, my S4 Active has been dying ridiculously fast. I woke up to unplug in from the charger, It was fully charged, when I woke up 5 hours later and looked at my phone, it was at 24% even though it was at 100% five hours ago. And I didn't use it at all in that time period. The screen wasn't on either. It's been doing this for about three days now, I've turned off my data, blue tooth, locations, and gotten rid of apps I don't use. I don't know what else to do. Could it be that I just need a new battery? I've had this phone brand new since April 2nd, 2014.
