With my Canon 5D4 I could take well over 500 shots with a fully charged battery and the battery would drain slowly if the camera is not used due to GPS. Even so the charge only reduced at 0.5% per day. The only time I get more rapid battery drain is using live view which does limit the battery but I always carried a fully charged spare.
I am now mainly using a Sony ML which certainly can cope with 500 images for a shoot which I have come close to a couple of times this year. I have always carried a spare but never had to use it yet.
