Few things to check if your phone is having battery power drain problem.

1)disable Cortana (Remove pinned too)
2)disable all unused apps from battery sense
3)disable nfc/double tap wakeup/Bluetooth/Hey Cortana
4)disable motion data collection (places visited)
5)change email sync to 2hours
6)change brightness to auto/low
7)disable glance screen if you have it

when things gets better you can start enabling 1 by 1, sometimes the location is also the problem if constant having LTE/3G on, my friends Lumia 1520 always runs hot when his at home with LTE on, found out the issue is his at the border of the coverage for U Mobile LTE, when we always meet up for drinking session or any other activity his phone goes back to normal temp and the battery drain stops... so now when his home he turn of data, change back to 2G, turn on wifi.

I tried it could never work? hhmmm

It says "Cant get internet now make sure you are connected to the internet" , this error shows that's its not supported afaik.

Note: Cortana and Music ID are region restricted, mostly to the US and a few other locations. If you do not see the icon described in this article, then you are probably in a non-supported region.

hmm it is in English, after checking I think the billing country has to be under US. my Microsoft account has 3 profile so its going to be complicated.

I would say Lumia 1520 don't really heat up as much as my old Lumia 920 while gaming, maybe because its running at full throttle lol, But its ok Lumia mostly cool down very quickly.

most phone auto restart comes from hardware overheating, I do not use a phone casing I have not had a auto reboot issue, last time I had was Lumia 920 over heat while charging with wireless charger.

what his talking about is regarding of this news. http://www.windowscentral.com/att-and-micr...ling-lumia-1520

I think its only in the US where at&t & Microsoft store sells them, now they are no longer selling the Lumia 1520.

I am sure you can still buy them around here / Nokia stores, replacement model with Windows 10 should be around the corner soon, in a few months
