Hello everyone, I just had a quick question as to how in the world some people are getting such great battery life on this wonderful device? I recently switched from the iPhone to this, mainly due to battery issues, and so far my experience has been terrible. I wouldn't consider myself a power user at all, maybe moderate if that, yet my battery will not last me a day. I actually am on my second Galaxy S4 as I took my first one back because I thought that I had some faulty hardware.

Anyways, as far as disabled features and such, I have all the "novelty" features off, as well as WiFi and Bluetooth. My brightness is also down to around 30% setting. Email account is set to push every 4 hours. I'm just stunned at how badly this phone eats away at my battery. It's just very frustrating being scared to use my phone because I don't want the freakin' battery to die. Signal strength is medium strength (3 bars, AT&T user). Any thoughts would be greatly appreciated. I'll post a screenshot once I download the Android Central app on the phone. Thanks.

My battery manager app said 40% of my battery was being used by '' Samsung knox '' which I don't even know how to open. I posted a screen shot and posted about it on the AT&T s4 forum.
