I mean , I guess they could cut the frame rate or other features to use less amps, but that would leave people screaming. I think the A1 or A1II had issues in cold
I think your real pro 8k cameras a lot more expensive than R5

I'm afraid you are right. I'm not asking it to hold up as I crank 30 frames a second or shoot movies. But it should hold up in cold weather when doing pictures one frame at a time.
It's the other way around. At 30FPS the battery and camera will be better because it is producing heat. Taking a few shots here and there will not use enough enough power to keep it warm.
I'm not able to post images, but at 30FPS the R5 II captured nearly 15,000 files in a few hours on one battery.
It isn't a battery temperature thing. I've had this happen multiple times to me in temperatures from -3 to +5 centigrade, i.e., not that cold. I've I shut the camera down, removed the battery back, then reinserted, the camera would work. If I kept the camera 'awake', not problems; if the camera went to sleep it was not waking up again. All of this suggests to me that it probably isn't a hardware problem, but rather something funky with how Canon has set up temperature monitoring software in the camera. It is almost like they actively want it to lock up consistently so we get an R1 (my R3 doesn't do this).
I've not had any problems with the R5vI nor do I remember any being reported. I too think it is a firmware problem. The going to sleep and not waking up has been reported by others. Either turn automatic shut down off or set for very very long time which is hard on battery life. Manual shutdown seems the best. After reading the entire early thread, that seemed to be the conclusion that it is firmware not the battery.
