My Moto Androids ran very warm too (especially the Droid 2G). With my Droid 3, I found that adding an extended battery helped.
Anyway, I hope this is not going to be an issue.
Last night, I was out with a buddy who has an S3 and I asked him if he liked it. Interestingly, his main complaint was heat.
As mentioned in this thread before the merge:
The S3 gets hot and the chipset uses the same exact fabrication process as the S4. Logic suggests a device that already runs hot (depending on use) will get hotter if a faster chipset and the gpu is pushing data to over twice the pixels.
The soon to release 800 is the first true evolution of the Qualcomm family, since a lot faster and a smaller micron fabrication process (less heat caused by resistance). That is unless it is clocked so high the fabrication process is offset by the faster speed, so still runs hot.
I wonder if the S4 refresh with this chipset will go beyond Korea? Some people assumed it was just the LTE radio that was updated for this chipset. Not correct.
