Hi, I have a S4 and it is two months old. Well, I've a battery issue with my S4 at the first month. Even I take a short call my phone loosed 1% battery. The same percentage loss continues with everything such as if I just launch camera from lockscreen or manually and shoot only one pic. Because of the dreadful battery life I even purchased an extended battery from mpj which I found almost positive reviews. Last week I stumbled upon the Google/location services are the real culprit! But certainly I don't regret to pick up the battery which I'm accustomed to it now lol.
