I did a test for a friend who wanted a static camera for a wedding. My two R5s got 30 minutes until the camera stopped because of the French law. Then I manually restarted and they ran for another ~10 minutes. This during the CA spring, around 25c outside, in the shade under an umbrella. I had very similar results with 4K High, and unlimited with 4K normal. I can say I am happy.
