I recently switched from the Pixel 10 to the Pixel 11 Pro, and after getting enough data in AccuBattery, the difference in battery life is much bigger than I expected.
Here are my average stats from 7 days each. Nothing scientific, just my usual everyday mixed use:
Pixel 11 Pro
Combined drain: 5.0%/h
Screen-on drain: 9.4%/h
Screen-off drain: 2.8%/h
Estimated screen-on time: 10h 41m
Estimated combined runtime: 20h 10m
Pixel 10
Combined drain: 7.2%/h
Screen-on drain: 12.0%/h
Screen-off drain: 4.3%/h
Estimated screen-on time: 8h 21m
Estimated combined runtime: 13h 58m
So compared to my Pixel 10, the Pixel 11 Pro is using roughly 31% less battery overall, 22% less with the screen on, and 35% less with the screen off.
The estimated SOT went from 8h 21m to 10h 41m, and the combined runtime estimate increased from just under 14 hours to over 20 hours.
Obviously AccuBattery estimates aren't a standardized battery benchmark and usage varies from day to day, but this is based on quite a bit of actual usage rather than a single charge cycle.
For me, battery life has been one of the most noticeable upgrades from the Pixel 10 so far.
