Hi guys, so I've been using my Lumia 830 for more than a week now, and I am sure I've seen some problems in it. In the first week, it was absolutely perfect. Battery was awesome, screen was amazing, and it wouldn't heat for anything (I actually play Rayman Jungle Run a lot). But now, a week or so later, the battery is becoming faulty, not totally, but it slows down quicker, and the phone heats up a (HELL FREAKING) lot when charging. It always heats up that way now, it never happened before. Did someone noticed something? I'm thinking of sending it to warranty check, cuz that warmth is in no way good and I'm afraid of losing my battery for good.
