Hey guys, I posted on here a week or so ago about having battery problems after the last AT&T Lollipop update on the Note 4. Things had gotten a little better for a couple of days, then started to get worse again. I finally contacted AT&T about it and the rep told me they were going to send a new battery before having me to do a factory reset. She told me if that didn't work (which I knew it wouldn't), then go ahead and do a factory reset. So I did the reset a couple of days ago and my phone has gotten significantly worse, with the battery AND now overheating. I've been reading on here and other websites about this issue and it seems that everyone that has had these problems got them resolved with the factory reset. I even booted my phone into safe mode and it still did the same thing, so I know it's not an app. GSam shows Android System using the most battery and today showed that the battery used 40% in 5 hours, and that was less than 30 minutes of SOT! Also when I charged the phone, the battery soared to 98 degrees. I contacted AT&T again tonight and the rep said they could do a warranty exchange, which basically means I will receive a refurbished model when I've only had my phone for 5 months and still owe $600+ on it. That did not sit well with me at all, so I asked if there were any other options and she said I could take it to the Samsung Experience Shop at Best Buy to get it flashed. I am definitely going to do that this weekend, but I was wondering if any of you have had to do this and if so, did it work? From what I've understood, AT&T won't let you go back to KitKat...
