I can't seem to find it right now, but there is another thread on this topic wherein the OP suggests that there is something physically wrong with some phones. He actually has a video with a proposed fix that has worked for some people.

I am suspicious that it is a hardware problem because my unit has been fine for the past 2 1/2 months. I am running stock, unrooted and was without a case until two days ago. I've made no recent changes to apps or settings. The only change was that put a bumper on and my phone has suddenly started shutting down and remaining unresponsive for a period of time. The battery is always at least half charged (before and after the event). After it decides to come back on, it is as if nothing happened. It doesn't really strike me as a software issue, it is more like the battery suddenly disconnects.

Re: [Q] Nexus 4 randomly turning off, intermittently not being able to restart
If phone becomes hot, theres a defense mechanism in which our kernel will make phone run at lower clocks which eventually gets our phone into sleep of death. So try one thing. If ever ur phone gets hot, dnt lock the screen and keep it on a cold surface, and once it get cold, press the lock button. See the diff!!

It turns off at night while in standby mode, charger unplugged and battery has 30-70% left. With stock everything and default settings. Why should it overheat? Only if stock firmware has such bug.

My phone does over heat at times and only after that it goes to sleep of death.. When you charge your phone, the phone gets heated too... Do you charge your phone at night before going to sleep?

Just wanted to update on this. I have not had a night-time shutdown since turning my WiFi off before I go to sleep. I still don't have conclusive evidence that it is related to WiFi, but I'm going to keep turning it off at night until it shuts down again (if it shuts down again).

Re: [Q] Nexus 4 randomly turning off, intermittently not being able to restart
No solution still but from discussions I had I found out also that some galaxy s3 users have the same problem. Also, it was suggested to me to install an app called "Wake lock" to prevent the phone or just its cpu going to sleep mode, as a temporary solution until we hear something from LG or Google. Just installed the app, will update if I see a difference

I can now conclude that WiFi has nothing to do with the random shutdowns. I had my first one in a while last night, and WiFi was off.

Re: [Q] Nexus 4 randomly turning off, intermittently not being able to restart
What software are you on? (rom/kernel/bootloader/etc)

Let's try to get everyone's stats so we can narrow this down.

I haven't had it happen a single time since turning off wifi optimization. I've been on francos kernel only changing to new nightlies, 4.2.2 bootloader, and cm10 linao+bionic

I'm on just the 4.2.2 OTA stock rom, stock kernel, stock bootloader. Only thing I've done is root my device and install CWM.

Do you have wifi optimization off? Or just turned off wifi?
