800h->mins

I saw “up to 800h” on much smaller battery (and AMD CPU), is it less effective CPU?
But probably, most likely, it is display, it is good to know what particular is used (not often provided info) but cannot find exactly NZ2 so this is for NZ1:

Interface Detail Consumption 2.5W (Max.)
Backlight Details 5.63W (Max.)
Total Consumption: 8.13W (Max)

Of course with testing in ~150 out of ~500 nits it shouldn’t be Max but should still be considerable nevertheless.

Or what else can consume considerably (on 2nd, 3rd places,.. ) in “browsing the web” (have anybody ever made a breakdown?)

And of course nobody say how much it (consumes and) can stay in s2idle (they don’t support deep/S3, do they?) with such battery 1w shouldn’t be a problem or it is still?
