I guess battery life just doesn't matter to me so much. I put my 6s+ and 11 Pro Max on charger each night and they have no less than 80% of battery when I do - and that's usually because I used them a lot during the day.

It matters much more to people who use their phones as their sole device, or to consume media or play games, etc.

But…I sit here all day, every day. I see no need to use my phones for games or media. And this is just one (or two) of the computers I'm using every day.

So, if updates cause shorter battery life I really wouldn't know I guess. I'm just using my devices as phones.
Today battery life was an issue with my 12 Pro. Different location for work, so away from power. Wasn't setting on charger properly overnight (maybe I bumped it or the cat did), so was under 20% when I left for work. And of course I didn't have my emergency backup battery. Then when it got to 5%, it shutdown. At lunch I go out to car and charge it up to 20%. DIed again at 5%.

Battery health is at 88%. It had been at 89% since 2021.
