[Q] Note 3 Overheating and Fast Battery Drain!? topic

Okay aside from me not having a computer to be able to develop on I still use my Note 3 and yes I am a flashaholic so I do continue to test other developers ROMs and find something that works for me. I am having some really bad battery drain issues on my Note 3 and it gets VERY hot.. i mean like really hot! First off let me say that I don't have warranty on it so i can't send it back to get another one. Whenever I use the phone for pretty much anything it starts to get hot and then battery drains like 20% every 20 min or so. I've tried flashing multiple ROMs and even using stock.. yeah STOCK. But each and everything that I have tried just doesn't help. I am at the point of like smashing my phone on the wall or something lol. Please if you guys have any suggestions please let me know. If i can't get this thing fixed then I will no longer be a Samsung Fanboy (that's a lie) lol. But thanks in advanced!
