[Nexus 6 Q&A, Help & Troubleshooting] jtr165:
AT&T Nexus 6 since December 2nd

Haven't messed with anything yet, unrooted, still locked, ATT boot logo, etc...

Mine never downloaded any of the ATT bloat junk, i did an NFC swap from my nexus 5 at the store...it downloaded all my apps, and even setup my homescreens/wallpaper exactly like the nexus 5, but never did that sim-activated grab of crap ATT apps...just pointing that out in case it matters...

ambient display is enabled. Wifi at home, but reboots seem random...

mine has only ever done the reboots, maybe once every 48 hours. This has never been a shut down though, its always back on by the time i grab it...its never rebooted while i was doing anything...just happens while its sitting somewhere and i hear that laughably bad ATT thing from across the house...particularly incredible while in bed with a wife that is a light sleeper (READ: "Baby, that giant phone you had to have...sucks")

haven't received the 5.0.1 OTA yet...I love the recent rumors that ATT gets to 'review' google's updates to the OS and decide when to push them...isn't that what they said wasn't going to happen?

the main thing i didn't see posted though...and i've tested this for weeks...when it reboots on its own, i can 100% confirm that the turbo charging part of the included charger does NOT work correctly...it charges the same on the turbo charger as it does on any other wall charger...The only way to fix this is to manually shut off then restart the device...not a huge deal, but being used to a roughly 1 hour full charge only to find out its more like 2.5 because you didn't know your phone randomly rebooted at some point...can be inconvenient at times...

not sure if that helps point to possible causes... I'm starting to get a bit annoyed with the entire nexus thing lately...I went through literally 4 nexus 5's because of dead pixel problems (luckily i bought the first one through amazon at google play pricing and got all of them replaced overnight without a question asked)...and oddly enough my only motorola phone before this 6 was a v60i in 2002...which crashed and rebooted so much i swore i'd never get another motorola phone...and look where I am...

either way...I did opt in on that $8/month insurance...I was promised i could bash the thing off the sidewalk, walk in, and get a new one...so may just wait and do that...

I just mentioned it in my above post, but again not sure if it helps the crazy smart guys with anything...

the reboot doesn't hurt anything, it returns to the lock screen and accepts calls/texts/email/etc. like normal...alarms still work also...you wouldn't know it happened, but in my case it seems to completely disable the 805's ability to 'accept' turbocharging...I've tested this multiple times, because at first i thought something was wrong with my included moto turbo charger...Whatever that hard reboot/crash thing is (mine has never just turned off, i hear the ATT boot sound and its flinging the lollipop boot bubble things around by the time i reach for it...also, for the record, this boot up is much faster than a normal startup), no matter what, the turbo charger won't 'turbo charge' the phone...if i'm under 10% i get an estimate of about 2 hours and 25 minutes....with turbo charging i've never seen an estimate of more than 1 hour and 14 minutes, and that was literally from 1% remaining...

if no one else is experiencing this, i'm definitely going to have mine replaced because of my mobile insurance thing...I've tested this at least 10 times; turbo charging works fine until a random reboot...doesn't work after random reboot until a manual shutoff/boot cycle is done...
