I am reporting extreme overheating just shooting stills. I had the camera shut down and the Canon battery that came out was extremely hot. This was a 90d Canon battery so not a high discharge version that ships with the R5. I am going to guess most stills shooters will want 3 spare R5 OEM batteries just to shoot stills for fun. For work I would believe many more.
So you got the heat warning usually associated with video while only shooting stills and then the camera shut down and wouldn't let you shoot anymore? How soon after could you shoot again?
Strange. I shot with it for 2 hours continuously this afternoon. I took over 1200 photos in 32 Celsius sun, with mechanical shutter and electronic shutter. I had 2 x LPE6 batteries in the grip. 57 and 58% charge showing.

I see a flame in the upper viewfinder. It was very hot out but a dozen different cameras used at that location in over 10 years and never had one shut down from heat.

Somebody above, asked how many shots you took.
Was there a reason you chose not to use the R5's own battery to see how that component worked too?

Could it have been the 90D battery? When it comes to electric power tools it is bad for them to have less current than they require. I'm not an electrical engineer so this is just a crazy out of the box thought. While the battery is compatible perhaps just for short usage as a fill in?

I just got the camera and believed my other batteries would work but for not as long. I got a blinking H in the viewfinder with the Canon 90d batteries and that is really bad for me to put up with.

No issues at all. Loving the camera
I don't have a grip so the battery was inside my camera getting hot. Did you have your viewfinder on high refresh? I did and it looked amazing.
I am thinking that the cancellation of my pre-order at the 11th hour could have been a blessing in disguise if the stills shooting overheating issue is true. But I find this to be implausible, as they would normally test a new camera’s performance in extreme conditions/temperatures.

The LP-E6N and the LP-E6NH are both 7.2V batteries, the only difference is their capacities which differ by 265mAH, with 1865mAH from the LP-E6N and 2130mAH from the LP-E6NH.
It is extremely unlikely that the battery plays a significant role in this problem.

Yes that would suck not to be able to use batteries that are kicking around. What is condition of your 90D battery,

I believe the new Canon batteries are rated for a higher discharge. The regular Canon battery could not keep up with how fast it was being discharged. This is going to make a lot of extra heat.
Maybe a QA problem. Let's wait and see what others find. Like that review of the A7S3 heat shutdown before R5 did. Could be isolated problem on one unit.

This is concerning. How many shots had you taken when this happened? Did everything start back up when you replaced the battery?

I was shooting very little but locked on a stationary bird off and on for an hour using the viewfinder in high rate setting.
If you could fully describe the state of the camera for that hour, it would help build a better idea of what the cause(s) might be. I.e. was the camera on and running the whole time, did it sleep, lens used, was AF running, etc.
I could imagine a stressor would be it running a fair amount in standby at a moment's notice ready to shoot. Such a scenario could be like recording video but without the additional heat of writing to the card.
