This is up there with the insane battery life of the M1-based MBPs

There's no reason to carry a charger from the time you wake up until you go to bed ... unless you're doing something very "heavy"

25h (pro max) or 20h (pro) streamed video playback is extremely impressive, as that means both screen and some kind of wireless data connection must be enabled, and those are usually the most power hungry components. I'm guessing this is at low display brightness, but still...

There is a big difference between the local video playback and the streamed video playback on the older model. The new model seems to bring the two in line.

    iPhone 12 Pro Max Video Playback: 20
    iPhone 12 Pro Max Video Playback (streamed): 12
    iPhone 13 Pro Max Video Playback: 28
    iPhone 13 Pro Max Video Playback (streamed): 25

As far as I know, the new models are slightly thicker and have a higher capacity battery which would explain the increase from 20 to 28. However, I can't explain why streamed video playback has more than doubled. Perhaps they simply fixed a bug?

This is a huge qualitative difference beyond just the numbers.

With a battery life that is longer than 24 hours, I can just have a single charger at home, and go through the entire day without worrying about charging.

It basically removes battery level from the things you have to be thinking about as you go about your day.

Maybe a hw decoder? (These already exist, but I mean, really tightly integrated with the browser.) Or some other offloading to hardware?

That would be my best guess

Maybe the variable refresh rate helps as well?

They did say during the conference that the new chip had a new video encoder/decider, so that sounds plausible.

The 8h difference would be rather attributed to the dynamic refresh rate.
