On my 11 Pro Max, on Sunday I shot around 1 hour of 4K video in Filmic Pro, and about 5000 RAW photos in Camera+. The battery was down to 10% after 10 hours (6 hours of "screen on"), which is miles and miles better than my XS which would have probably lasted about a third as long under the same workload.
