This thread details the teardown process, modifications made and some important findings: http://c.tieba.baidu.com/p/6848700307?pn=1 He replaced the two thermal pads that did not

I differ in opinion. If I where using it as designed, yes. The fact of the matter is that canon disclosed up front that there are recording limits. They can not anticipate every single usage sc

At the weekend I bought the enigma that is the EOS R5 for myself. Foto-Meyer in Berlin were able to find me a rare unit. A huge thank you to them! What all EOS R5 owners have in common is that they ha

Try a battery pull while the camera is still on, both just after stopping a record and if that doesn't extend the subsequent recording time, while the video is actually recording. Check if the camera "remembers" the remaining time limit available when you plug the battery back in (details here).

I tried this.

I turned the camera on let it sit at idle with no card in camera, once I got the overheat warning, I shut the camera down. 

I then grabbed my 1TB cfexpress card put it in camera, and the time allowance for HQ recording read 10 minutes.

Started a recording, changed aperture, and iso, as soon as you open the battery door camera shuts down, pulled battery and reinserted the battery.

All values were as left at shut down, and 10 minute limit remained.

EOSHD testing finds Canon EOS R5 overheating to be fake, with artificial timers deployed to lock out video mode

I wonder if this strange battery door “feature” is to avoid the battery being pulled? What other Canon camera has ever done this? Any camera at all?

And how would you use a dummy battery for DC power?

So it is idle with no card... yet still overheating warning shuts it down?

Yet with an HDMI cable attached it doesn't do this.

More fakery from Canon, in my opinion.

Yes with card in camera but at idle ( not flipping through menus or anything ) no operation other than being powered on.... STRANGE. 

Camera doesn't provide any time info until a card is inserted in camera, with card inserted, at idle, the camera threw overheat warning at 22 minutes indoors in cool air. Thats half the time than when I was recording continuously for 37 minutes through external recorder indoors and outdoors in smoldering heat. 

I don't think ambient temps  play much of  a role at all. Seems this whole deal is set in motion the minute you select HQ or high frame rate modes.

This is all software in my eyes.

What's your recovery time like?

I just had mine sat for an hour and a half, but couldn't get more than 5 min of 8K on the clock

That is absurdly fake.

The camera body was even cold to the touch.

I'm experiencing the same with recovery. My R5 is currently showing 15 minutes of record time available in HQ, this is after the camera has sat for two hours.

Camera is cold to the touch as well.

Thanks. It's not clear you tried the specific experiment I outlined. The battery should be pulled while the camera is recording internally to the card (abrupt shutdown), somewhere near where it would thermally shutdown. Then the battery should be put back in and check what the available recording time the camera reports.

In this test the user was able to get the full 15:00 available following a thermal shutdown after just 25 minutes in the freezer.

Yeah, I pulled battery while camera was recording. As soon as you open the battery door, camera shots off anyway. Pulled battery and then reinserted battery, available time did not change.

Thanks. The fact the camera shuts off as soon as you open the battery door means it's using battery-door sensor to perform an orderly shutdown before you get a chance to remove the battery. Unfortunately that makes the experiment more difficult to execute. The only way around it would be to find where the battery door sensor is and manually hold the sensor in while the door is open, then do the video recording, then pull the battery.

and took battery out for too, wonder is that the reason to reset the timer?

I think others have tried battery removals without any effect on subsequent available recording times. The difference in this test vs any others I've read is he kept the body in the freezer for 25 minutes. That's much more definitive in disproving the firmware cripple timer theory than putting ice on the camera or adding better heat sinks.

You may want to check, but there is a button cell to keep the camera time

Look more for something like this to reset time.

If this reset the recovery time or recording time, it's the 100% proof that there is no valid temperature reading, but time based only

This is for 5D, but I guess 5R have something similar
