The rate at which you use up your “battery juice” depends on how you shoot and what you shoot. Of course, the ambient temperature also plays a part. When recording movies continuously, Canon claims the LP-E6N battery will become exhausted after approximately 1hr 40min, or a little less in colder conditions. However, that figure for the canon eos r battery life seems a little misleading to me. When I’m out on a video shoot I seldom film continuously, although sometimes it does happen. In my commercial videography world, I shoot many short clips of b-roll footage and some longer piece-to-camera video clips. Under these real-world conditions, a single battery will last me two-thirds to three-quarters of the day. So, for most of my commercial video shoots, I never need more than two LP-E6N batteries. The number of photos that the EOS R can take on a single battery pack also varies, depending on your shooting style. According to the Camera & Imaging Products Association (CIPA) guidelines the Canon R can take 370 images on a single charge. But many users report wildly different results. For instance, on Reddit Moenke said, “did ~1000 photos before the battery died for me after 4-5 hours.” While Bryan Carnathan of The Digital Picture reported between 670 and 1510 shots on a single fully charged battery. So real-world and the CIPA rating somewhat far apart.
