Random shut off after upgrading to stock 5.1.1

Never had a reboot issue with KitKat or Lollipop on my Nexus 5. However, since upgrading to 5.1.1 from 5.1, my phone randomly turns off during usage. Its a power down and not a reboot as I need to manually hold the power button to get it to boot back up.

I've not been able to find a pattern to the crash but usually its an app that either uses the camera or something like Hangouts doing a call. Battery typically is between 45-80% when this occurs and app usage is varied. Happens about once a week. I'm able to browse the web or use Talon and get the battery to 30-50% without stability concerns. It just seem that certain apps expose the bug.

Couple of additional data points. If I have it connected to an external battery and battery stays above 95%, power down doesn't happen. In addition, if it boots back up & its not connected to a power source it will then power off again. The next boot will do an ART rebuild of cache.

I searched, but haven't seen another report like this.

[HELP] Unrooted Nexus 5 randomly shut off, now frozen on Google logo at startup

I didn't drop it or get it wet or anything, it was just sitting on my desk and it randomly shut off. I've tried shutting it off and on again but it just comes back to the google screen where it sits frozen for about 30ish+ minutes before it shuts off, I can't turn it off otherwise, if I try turning it off it just turns itself back on so I can't shut it off. Is there anything I can do to save my data (or even better, fix my phone) or am I screwed? I also don't have USB Debugging turned on so I can't get stuff back that way either. My phone is not rooted and running stock android 5.1.? (Don't remember my exact version but I think I've missed the last 2 minor updates)

samsung Galaxy S4 I9500 is shut off itself + Battery Drains after turning it on!!!

I've been using my S4 I9500 for about 3 weeks. everything's fine but, the phone just shut off itself randomly while using it. After That I can't turn it on again unless I remove the battery then put it again, but unfortunately when I turn it on ... 3 seconds and same thing happen again. When my S4 I9500 shut off itself battery drains super fast, I mean for example before it shut off itself the battery was 60% ,, after I turned it back on it is 12%!!!!!!!:crying::rolleyes:
This also happen sometimes when I launch my camera.. :confused::(

Neither the battery nor the phone always feel warm when that happen. I totally have no clue why this happened. anyone here is experiencing the same thing with your s4 I9500? :confused:

Hope That Someone Really Helps ME :o:D
PS: I Rooted my phone yesterday with the help of a post on XDA Developers forum But That happened also before rooting it... !!!
Note: My S4 I9500 is running Lollipop Android Version 5.0.1

Thank You all!!!.. :fingers-crossed:
