I'm experiencing a heating issue and it cause to drain battery fast it happens lot in Developer preview then after Lumia cyan upgrade I get that same issue again so anyone know how to fix this issue?
Best thing you can do is turn off the phone, let it sit there for 10 minutes or so. I've gotten 2 Lumia 1520's and they both have overheated. I just let it sit to cool down, cancel all background task, turn off Wifi, Data, Bluetooth, etc. Hope this helps.
Happened to me yesterday. Just soft reset, correct the time, shutdown and let it cool for awhile. Most of the time this is due to some app that failed to exit properly or suddenly eats alot of resources. In my case, the culprit was the new clock plus app I downloaded. So i just uninstalled it. I don't think though that this is a L1520 exclusive problem. My L620 used to have this kind of problem. So as other Lumia units in another forum.
