"Change or Charge Battery" Error or Bug with Canon R5 Mark II

Both the camera and battery are new, so not surprising there may be "insufficient" reports at this time.
Has anyone tested the R5m2 with the LP-E6NH batteries (from the R5) under these same conditions (very cold) and observed the same error messages (or battery drain with the camera)?

Yes, I have tested the LP-E6NH in the R5m2. Same drainage issues. I’ve also tested the mark2 batteries in my mark1 with no drainage issues.
I just received my mark2 back today and did a R5m1 vs R5m2 test. I set both cameras up outside with fully charged batteries (99% and 98%) and set a timer for 25 minutes to check drainage. The original R5 dropped from 98% to 96% while sitting idle. The Mark2 dropped from 99% to a blinking 1% remaining after the 25 minutes. How does Canon tell me this is normal with a straight face. Very disappointing. I did photograph this test to document it for Canon; I doubt anything will come of it, but I’ll hope (for now).

Thanks for the update. Sounds like it is the camera design, not the battery.

I have performed similar tests with 2 R5IIs now and have gotten similar results. I'm getting ready to head out now with temps hovering around -12C and I am leaving the R5II at home in favour of the R5. The last time I took the R5II out in these temps I ran into action and had no power when I went to take shots. This has never happened with the R5. I'm extremely disappointed by this as well.

I did a test this morning, the outside temperature was 25*F, I left my R5M2 outside for 1.5 hours and tested the battery level every 30 minutes. After the first 30 minutes the battery level dropped about 3%, at an hour it was down about 15%, and at 1.5 hours was down by about 20% total (63 at start to 43 at finish). This was probably not a very scientific test and my weather conditions were not quite as extreme as what others are reporting. I will keep a watch on the weather as it is supposed to get colder over the next few days.

I was out for 2 hours, with the R5 II and a fully charged battery (LP-E6P). And lenses I've been using often on the R.
Temperature was 2° Celsius or 35.6 Fahrenheit.
I took 86 pictures without wasting time on exposure measuring, reviewing or focusing. 56% battery capacity were left.
I guess with the EOS R, situation would have been totally different.
By the way, the same happened at much higher temperatures, around 20° Celsius. But then, I still played a lot with the new camera...
So, naively, I contacted Canon Support. "We've never heard of similar issues, maybe your battery wasn't fully loaded, or you ran GPS etc..."
Next time, I'll test 2 cameras simultaneously with the same settings to get more reliable data.

I thought of an interesting test while I was out today. When I have time I'm going to put the R5II outside till the camera reports a significant or total drain. I'll take that battery out and insert it in the R5 and see what it reports.

Nice idea. You could put both cameras in the fridge, close to 4 oC.

When I took my battery out of the R5 II, I inserted into the 5 D IV and EOS R.
R5 II: 56%, 5 D: 55%%, R: 58%.
In my case, discharge was real.

I was out on 1st Jan with the R5II for a walk round a local nature reserve, temperature about 2-3°C so about fridge temperature. Took about 63 photos with the 100-400, quite bit of holding servo AF on subjects before shooting, bluetooth link to my phone on for GPS tagging with Camera Connect, camera was on for about 1-1.5h with default EVF sleep settings etc. Didn't note the battery % figures at the time but don't remember thinking "jeez, that's going down fast" and it's still at 60% now after having sat in the camera for a few days. Will pay more attention next time I'm out (given to be cold again this weekend so hopefully will get a chance to test then) and report back.

I updated my post above with photos of the battery drop. Since I just received the camera back from Canon Service for repair, and they deemed the camera to be functioning normal; does anyone have any suggestions who to contact to escalate this issue? I left a VM with the technician that worked on my camera, hopefully I’ll get some answers from him. But I’d still like to let Canon know that the issue was not resolved.
Thanks for any info.

I have thought about this. The drain we are seeing happens at colder temperatures than the stated operating window which if memory serves is 1-40C. Canon could simply shut the door on that basis. I hope that isn’t the case. I have a specific use for the camera, and I think it is reasonable to expect that the newer model will have equal or better performance in adverse weather conditions. From what I am seeing it is clear there is an issue. The best-case scenario is that all production is affected by this, and Canon gets enough reports to be moved into action. Worst case is that this affects a small portion of production, and it takes a long time to acknowledge and address if ever. It’s the if ever that really concerns me. I only have access to my R5II and a friend’s which are both showing the same drain. If one wasn’t there would be a basis to say that one unit was faulty, and one was fine. Hopefully Canon will receive enough reports of this issue to investigate it. That said I think the only thing we can do is keep up the pressure and implore anyone else experiencing this issue to report it to Canon.

Update Pt. III… I received a return call from the tech that originally evaluated my camera. He reviewed the images I posted above and forwarded them up the chain. He did mention that there have been additional cases with battery drain in the cold and there is not a fix as of yet. Below is the email I received pertaining to a test they’d like me to run. I’m encouraged there is some movement on the issue.

I have a request from our Higher Headquarters. Thank you so much for your time and understanding​
​
can you ask the customer to do the same test using their camera and when they get the camera to show the low battery indicator, can they use the camera to take a picture so Canon Inc. can look at the exif data information contained in the picture. They want to know what temp this happens at. The picture shows them this info.​

That sounds like good news. I opened up a new ticket today in reference to the closed one. It contains additional information and test results. hopefully I'll get a similar response. Do you mind asking me which service centre you are dealing with? I am in Canada, so dealing with the central service centre in Brampton, ON.
