I just got the s4 on Sunday. Right away I updated to the newest software ota. Ever since I've had the phone the battery life has been horrendous. It drains almost 30% an hour. Google services uses 78% media server 9% and display 8%.I disabled all of the Samsung services, WiFi, GPS, battery saving mode on.... What gives? I shouldn't have to put this much effort into battery issues. Any ideas? Or am I spoiled from my iPhone 5 battery life? Thanks.
