Hi, I bought my phone last week and have really liked it, but there is a really big problem. The phones battery will last maybe 5 hours and will get really hot. I installed juice defender, turned the brightness all the way down and turned off location services in google now, but nothing has changed. I'm running jelly bean that I downloaded through kies. I'm not sure if it's a problem with the phone or the battery. So how can I resolve this issue?
