I suspect it's possible that IF your camera had its wireless mode enabled, AND was in proximity to your phone which had also had the Canon Camera Connect App running you could have had a communications link running that drew down the battery. The sensor is a new model, and this is Canon’s first body to feature in-body image stabilization (IBIS). In combination with the high speed data throughput of the RF mount, this can combine with the image stabilization in a lens to offer, in the right circumstances, up to eight stops of image stabilization. Number of shots is not a great indicator of performance for these cameras. They are super fast and the main source of power drain is maintaining the EVF and / or LiveView. If you take a lot of bursts at 20 electronic, you'll get many more shots conpa9to somebody who spends a lot of time composing and only takes a picture occasionally. In both cases, I think the actual number of minutes spent using the camera would vary far less. The blue columns represent the gross usable power in the battery, which Canon won by about 10-15%. The orange columns represent the percentage of the battery’s power that is applicable to the higher-wattage mode allowing for 12 frames per second before the waning wattage fails over to a lesser framerate mode. This is because the R5 needs faster read/write speeds, as it shoots stills at 45MP compared to the R6’s 20MP, and can capture 8K Raw video footage, with 4K oversampled 120fps video footage. Capturing that kind of video data simply isn't possible on today's SD UHS-II cards. Canon EOS R5 vs EOS R6: Battery life

Camnostic tested multiple battery situations (including external batteries attached to a “dummy battery shaped like an L-e6) to chart real world expectations and even compared these results to third-party brands Neewer, Big Mike, Watson, and Powerextra. Lotus 7 is absolutely spot on with this statement. With the power switch off, for my 1DX and 5DS series bodies inserting a card or battery causes the activity light to flash indicating that the camera has been triggered out of its low power standby mode. The Duracell multi-fit camera battery provides long-lasting lithium-ion power for a range of camera makes and models, allowing hundreds of photos to be taken on a single charge. Of more interest to the rest of us is the EOS R5's new battery – the LP-E6NH has about 14 per cent more capacity than the slightly older LC-E6N. Those who already own Canon kit should note that the older model of battery is still compatible with the R5. You can also use a Power Delivery supply to charge the R5 via its USB-C port, saving you popping the battery out when it’s time to recharge.It is similar to the reason that many modern cars can't sit nearly as long as older vehicles without depleting their battery beyond the starting point. Keyless entry systems, particularly the passive types, involve both the transponder in the vehicle and in the key fob to stay in a low power sampling mode looking for activity. So even without any content theft prevention system, most modern vehicles are never fully asleep. While there are multiple tests and findings in the full report, one area that is worth looking at on its own is a test that Camnostic did to see how the Canon-branded batteries performed against those third-party options, all of whom claim better performance than first-party batteries. This is the correct answer (based on my RP and I'm sure the R5 is the same). The charging source, whether it's an AC adapter or power bank, needs to say that it supports the "Power Delivery" specification. Just having a USB-C connection isn't sufficient.

The R5 is a computer that happens to record images and video. It's only really "OFF" when the battery is physically removed." I pulled off around 2800 images on a 70% battery before it died while covering a house fire at night. 120hz high speed display, and pretty high brightness. Mainly remembered to turn the camera off between shots unless there was a lot of action going on, and all were shot at 12 fps. The camera turns on by the time you pull it up to your eye, so I never had any issue with the camera not being ready if it had been turned off. The R5 in particular grabbed the attention of the photography world due to its high resolution and fast frame rate of up to 20 FPS. While Canon did put a lot of emphasis on the video features of the R5, I am a stills-only person and will hence review the camera from the standpoint of a photographer. I would like to note that I have been a Canon-only shooter for all of my photographic career and owned a few different 5-series cameras, so I will be comparing the camera to its DSLR siblings mainly.Many believe, incorrectly, that the LP-e6NH has more usable power than the LP-e6N that came before it, but this is not the case. In Camnostic’s real-world testing they found that using dozens of individual batteries over that period proved that the newer models don’t push more milliamp hours of power to the camera but they do keep their wattage up over a certain threshold through the use of about two-thirds of the battery’s charge, maximizing the ability of the battery to power the most resource-heavy modes of the camera. For example, the highest framerate while using the mechanical shutter — 12 frames per second — is particularly power-hungry. One of the biggest differences between these two full-frame cameras is their sensors. While the Canon EOS R5 has a brand-new 45MP sensor, the EOS R6 uses a chip that's very similar to the 20.1MP one found in the Canon 1D X Mark III. There's also a theoretical advantage in low light (see below). Naturally, landscape photographers will err towards the 45MP resolution of the EOS R5, and the R6's 20.1MP might be considered a little low, with the older EOS R offering 30.3MP. But it's important to state that there isn't necessarily a 'better' when it comes to resolution, only what suits your style of photography. Canon EOS R5 vs EOS R6: low-light performance Many batteries in current use could be quite old. The LP-E6 battery first appeared on the EOS 5D Mark II, which came out in September 2008. If you have this model, or a model out at around the same time, the batteries you are using could easily be more than a decade old and in that time they might have been recharged hundreds of times.

It’s obvious that the Canon first-party batteries are wildly better in performance than the four third-party options tested. That said, some users might not notice.The video specs for the R5 look fantastic, 8K 30P 4K 120P and the ability to pull 35MP stills from 8K video is really exciting. But I would start with a PD 3.0 supply and go from there. But again this is very risky as Canon hasn't given any specs, so try at your own risk. Personally, I carry three sets of batteries for my R5 with BG-R10 battery grip as I'm a belt and suspenders type. I've never used more than one set of batteries and assume that one set of batteries should last about 1,000 shots. Also from the rumor mill, people say that the camera/lenses can malfunction below 60%. I've never seen this but carry extra batteries just in case. All NH batteries overstate their actual performance – even Canon’s,” Camnostic found. “The third-party versions all claim to have more juice than the Canon, and every one of them actually has less power. Here is perhaps the most important chart on the topic: the real-world amp-hour measurements for each brand using a special Dolgin Engineering device that charges the batteries fully, and then measures the draw to 0. The Y-axis on the left in chart below (amp hours) is compressed to better show the differences.”
