EOS R5 Ml II hot after idle in the backpack

Ok here's something strange that happened to me today for the first time in 2 years I've had this camera.

I came back to the hotel around 19.30 after a day walking in Montreal. I've kept the camera always hanging on my neck with the strap just to put it back into the backpack for the last hour of walk. I changed battery just a few minutes before putting the camera in the backpack around 18.00, to shoot a couple of photos, so battery in camera was at 100%. Once to the hotel I took the card out to transfer pictures on an external SSD, then I put card back in, put the camera in the backpack again and I left the backpack on the table, had a shower and went out without the camera.

I came back three hours later, opened the backpack to take the camera to download some pics on the phone and found it very hot: the heat was concentrated at the back, behind the LCD and in the battery slot. The camera switch was off. When I turned on the camera the battery was at 50%.

I removed battery (that was a little hot as well) and let it cool down, it took 10 minutes.

The camera is working fine, but I have no idea what may have happened.

Did you ever switch the camera off?

Canon battery or aftermarket?  Since you have multiple batteries, I would suggest you test with each to see if the problem is associated with just one of them.  If it is a faulty battery then you should stop using that battery and recycle it.

"Since you have multiple batteries, I would suggest you test with each to see if the problem is associated with just one of them.  If it is a faulty battery then you should stop using that battery and recycle it."

If it's the same on all batteries, then I suspect it is likely there is a fault in your camera and it needs service.  The camera should not be draining that much from the battery when switched off.

Greetings, 

Are you using a Canon lens?

In addition to a faulty battery or hardware, ensure that you have Bluetooth and Wi-Fi disabled when they are not being actively used.

This was my next line of thought. Disable wireless communications and what is attached to the lens mount.

Some of the third party mount adapters were known to drain the battery even though the camera was switched off.
