About this deal
TechRadar reported excellent battery life at 2300+ shots with a LP-E6NH and EVF (unclear if 60 hz or 120 hz). There are signs of economizing on the EOS R6 when it comes to the monitor and build quality, though. The monitor is still a vari-angle touchscreen – at this end of the market, we’d expect nothing else – but it’s 1.62MP instead of 2.1MP, and it’s a touch smaller, at 3in rather than the EOS R5’s 3.15in. If you prefer not to connect via Wi-Fi to the camera when it is off, either set [ Airplane mode] to [ On] or set [ Bluetooth settings] to [ Disable]."

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. My Ravpower RP-PB203 powerbank is 18W and it works fine to charge the R5 (or R5 with grip), as long as the power to the camera is off.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. You can even display RGB instead of brightness histograms, which is a welcome improvement. The one thing I dislike about the R5’s viewfinder is its eyepiece. It is considerably worse than that of Canon DSLRs in two ways. First, it is smaller and not as good a fit to the eye, so sunlight can penetrate more easily. This can be an annoyance in some situations but an actual problem in others. For instance, in the snow on a bluebird day my right eye (the one on the viewfinder) started watering after only a short while of shooting. Second, the material used is much harder than that of the earlier eyepieces, making it much less comfortable to press your eye against the camera for longer periods of time. Unfortunately, there don’t seem to be any aftermarket eyecups yet.

Store the battery with the protective cover attached. Storing the battery when it is fully charged may lower the battery performance. I've found my R to show low voltage when I used my old dummy battery and power supply, but it works just the same. With DSLRs I could simply hold the camera up to my eyes without having to turn it on to figure out if I liked the way a scene looked through the lens. Now I need the camera to be turned on to do the same thing. Of course, I could simply leave the camera on, but the decreased battery life of mirrorless cameras makes that a suboptimal choice, especially when on longer trips.

The EOS R5 is still substantial-feeling, with a deep grip that makes it easy and comfortable to hold, but it’s also easy to tote around without it feeling burdensome. Weather resistance is said to be up to the standard of Canon's 5D series, which professionals will tell you means the R5 should withstand troublesome weather better than some photographers. We’d be confident in most situations. Professionals are hard on their Canon gear, and no other single piece of equipment shows the wear and tear more than the humble camera battery.

Unfortunatly, the R5 "power switch" does not physically disconnect power from the processor. Regardless of the switch position, power is supplied and can be used by the processor and wireless transciever to run Bluetooth and WiFi as well as the systems which recognize and scan the directory of memory cards when a card is installed. This happens if the switch is in the "OFF" position. Keeping Bluetooth and Wi-Fi connections in operation will use battery power to keep the transciever "alive". The wireless operation is discussed on pp. 597 of the R5 Advanced User's Guide: One final area where the R6’s reduced bandwidth needs are reflected is battery life – where you can expect 490 shots on the R5 using its monitor to frame up, or 320 using the EVF, the R6 is rated to shoot up to 510 shots with the monitor or 380 with the viewfinder. 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.
