My new 128GB 6s+ got very hot yesterday while shooting 4K video. I got a warning that the flash was disabled due to high temp. I was shooting a combo of stills and short video clips for about an hour.

During regular usage I've noticed the case gets hot near the camera. Should I be concerned?

BTW: Despite the warning, the video quality of the 6s+ is exemplary. I pulled it into Final Cut on my MBP and I cannot believe it was shot with a cell phone. IMHO, this rig can hold its own against a lot of higher-end video gear.

Thanks in advance.

It should get warm as your are using a lot of the CPU to process the 4K video. The phone will protect itself and will not allow you to damage it. The 4K videos on my Sony 4K flat screen are awesome. Hard to believe a phone took those images. Glad I got the S+!

Thanks, all. Glad to hear it. I originally got the 6s but exchanged it on day 14 for the 6s+ and I am really glad I did!
since you've done a full hour of intensive use, could you remember how much battery it took more or less?

Caveat: These are just my recollections. I shot stills/video during a 2.5 hour workshop. Total camera time probably ~1 hour.

-9:03 am: ~90% battery

-11:33 am: ~33% battery

Total 4K video capture ~30 minutes plus 60 stills.

*Wifi was on and uploading >5 GB to my iCloud during the shoot.

I'm overjoyed at this performance. At the time of the shoot, I'd had the phone less than 24 hours.

Seems decent, thanks.
Well if I'll have a Samsung chip and the same situation will end up at 15% battery, id be really pissed.

But regarding the heat, yup the phone should be really hot after that.

Shooting 4K videos on a GoPro camera makes the camera very hot indeed. Nothing to worry about. Shooting 4K video will be one of the most intensive things you'll do with the iPhone.

I know some other brand phones that will freeze from overheating.

My 6S+ does get warm shooting 4K. It is very processor intensive. Its essentially capturing an 8MP image 30 times a second for however many seconds or minutes you are recording. I would assume it also more battery intensive than 1080p. The video sure looks nice though.
