The issue with me is that the phone works perfectly and the battery life is amazing if i do nothing or only answer phone calls and text some messages!
(NFC,Bluetooth,Location ------> Off) The issue begins when i begin to run an app or game(No matter what app or game,even WP7.x games that worked perfectly on my HTC RADAR)
after 10-20min of playing the game or running the app the phone begins to overheat very much and a related massive battery consumption is caused!(about 20%-30/hour discharge rate)
When i exit the game/app after 2-3 mins the phone cools down and returns to normal.
1)My first HTC 8x suffered from this issue,changed motherboard and battery through the warranty and the issue never was fixed!
2)Replace my HTC 8x after 1) through warranty but even the new device suffered from the same issue!
3)And at last now i switched to Lumia 920 thinking that i will get rid of this f***** issue but again the issue even followed me even on Lumia920!!I'm afraid this issue is becoming my shadow LOL!!!!!
So after 1)2)3) i can only consider that this is cause becaus of a firmware/OS bug!The annoying thing is that MS/Nokia/Htc (mainly MS) are pretending everything is ok!And doesen't even provide us an update-fix or at list give an official report about the problem (VERY UNPROFESSIONAL IN MY OPINION)!Behavior like this is forcing people like me that are suffering from this issue to switch back to iOS or Android!
I can only wait and hope to see if GDR3 will fix this issue or at least MS will say anything about that!
What's the point to bring new features and port apps/games on WP platform if we are unable to play/execute (and disable almost everything in settings) because of this issue!?!?!?!
