Hi there! I had this problem with my Nexus twice now, that's why I'm bothering you.

Long story short - I plugged my phone to charge in the evening, woke up in the morning to find that the phone is VERY hot(area around the camera on the back) and switched off, and won't turn on. After doing a battery pull the phone switched on, the battery was full and the temperature was at 46C. It happened to me on the Monday night but I thought it is just something silly, but it happened to me today again. I was not using any hardware intensive application before I went to bed, just writing emails with my GF.
Any ideas?

Leave it in a chocolate tin to keep it cold, with ice below it, charge it in the morning and see if its a app

I'd do a factory reset and see if it does the same after another night of charging with no apps on it.

If it does the same, the phones probably defective.

Have you modded the phone since you got it? Like rooting or installing any mods.

How many apps have you installed on it? Any that may keep running in the background?

If it does it again then I would advise going into Settings, Backup & Reset and restore the phone to factory settings. Then put the phone back on charge for about 8 hours and sede if the temperature goes up again. As mentioned it may just be an app thats making the phone go hot but if it goes hot after a factory reset then you will need to send it back for replacement.

Mark.

The first thing to go from heat damage is the battery. 50 degrees celcius and up is in the battery killing temperature range.

As long as it's under warranty I guess do what you want. But I'd highly recommend setting up an app like setcpu to force a lower clock speed when temp>44 celcius, just to be safe. No sense in killing a battery while trying to fix the problem.

I leave mine on charge overnight, and it doesn't do this... so I'd agree with others in that it's either a rogue app or a duff handset.

Didn't they say that one of the CyanogenMod devs was working with Samsung on the Nexus? Maybe he implemented "sleep of death" as a feature

The phone is not rooted, it's not running any mods. The only two applications that run constantly in the background are the DoubleTwist AirSync module and Llama profile manager(and the default weather+news widget). As both have not been tested with Android 4.0 it may be it. Is there any good app to display the current CPU usage by a process? Just like "top" in the console.

That's pretty much the same thing that happened to me. Except that being hot explains the issue at least partially,as the phone will switch off when overheating.
