I had 100% charge on my s4 on friday morning at 7am. By noon with light usage and majority of the features(gps wifi bluetoth air gestures) turned off, my battery was down to a dismal 42% by noon. By the time it was 5pm, it was down to 10%. I was hardly using the fone since I was at work. My battery usage details showed that the screen was taking up 81% of my battery . I went back to at&t on saturday and they gave me a new handset. I have been on this handset for 1.5 hrs now and the battery has gone down to 82%. This is so so disapointing seeing the sort of battery life other people on this forum are getting. I dont know whats wrong with 2 brand new handsets. Also last night my screen usage randomly went down to 48% which is the lowest I have seen it go so far. I have not even started using this phone to its full capacity and this is the state of mt battery life
