gets warm during use

[dancing-bass]

Not an N4 user, but as far as I understand the glass back is acting like a giant heat sink for the processor. I don't know if that was the intentional design or not, but that appears to be what's happening. Plus (as others have said) there is a quad core processor under there.

As well, the processor is thermo-protected. Meaning it will throttle itself if it's getting dangerously hot. If you continue to use it and internal temps climb beyond what it's pre-programmed "safe" levels are I would imagine it would force a power off/on cycle to completely shut down all load on the CPU/GPU. I don't see how this is an issue. Mind you I have not used one so I don't know how hot it does get. I do know my Gnex can get pretty warm if I'm pushing it hard (and it's overclocked to 1.5 instead of stock 1.2).

Navigating with Google Maps with the screen on makes the phone heat up a lot after an hour or so, but not enough to be concerned.

My Nexus 4 gets hot too, mainly playing games, but that's how all smartphones are. No biggie.

I used an app that continuously taxes the CPUs and GPU but I forgot what it's called. It was shown in another thread like this one.

After 10 minutes it was almost at 50 degrees Celsius and still climbing. Is that normal? It was crazy warm to the touch at 40 degrees Celsius and if it got to 50+ in my hand I couldn't hold it.

Just got mine 3 days ago and so far it appears perfect. No serious hard use yet, but it always feels cool to the touch. Maybe it is from one of the later batches. No problems at all so far.... fingers crossed!
