Lumia 950xl power failures.

Has anyone else experienced random power failures lately on the 950/950xl? Ever since the last month it's gotten particularly bad, worse this last week. 18 times the phone turned off yesterday. Of those 18, 7 times it rebooted, 11 times I had to do battery pull. Today phone has done this 6 times. Hard reset didn't solve issue. It seems to happen most at night, 90% it's when sliding up to unlock screen. Phone has no physical or liquid damage. If you've experienced similar issues let me know so we can get this resolved.

No, none. Sounds like you need to get yours repaired or replaced.

There was of course a firmware update out today and those can sometimes fix low level issues, but still sounds like faulty hardware to me.
