OK, it's only a couple days in, but man, it gets pretty damn warm. 

How to describe - not hot enough to make it burn or untouchable, but hot enough to know it's a hell of a lot more than warm.  My guess would be about 35-45C.

It gets hot at the top are only - browsing, using the Nokia Maps - stuff like that - for say 20 minutes.

If I hold the top area, my hand acts as a good enough heat sink to pull the temp down.

Hopefully other 920 owners will be aware that the 920 has had some overheating issues on *some* phone (I don't know the numbers).

How hot does your 920 run?

What's too hot?

Cheers,  Duncan.

Mine gets warm but nothing I'd get concerned over.

The weather has been a lot warmer recently too, we've had 22+ degree days recently! lol

GPS and heavy data usage tends to heat up phones.  My GN gets real warm when the screen is going non-stop for a while and it's using GPS or data.

Mine was doing that on the first day. I did a reset and now it doesn't seem to be getting anywhere near as hot with similar usage.

Under heavy use the Snapdragon S4 SoC does tend to get warm to very warm, as it dissipates voltage leakage at transistors as heat. By US S3 on the same SoC in 3D gaming and such tended to be far warmer than my International S3, and I presume that voltage leakage is the reason the US S3 with its 28nm dual core has slightly worse battery life than the Exynos 32nm quad core, which has far superior High-K+ Metal Gate transistors (despite everything telling you 28nm will have better battery life). Interesting Anandtech piece on it here in relation to the revised iPad 2: http://www.anandtech.com/show/5789/the-ipad-24-review-32nm-a5-tested

Anyways, long story short, it is quite normal under heavy load for S4 SoC devices to get quite to very warm under a heavy load.
