The iOS option to charge battery to "80% Limit" shouldn't just be for iPhone 15

Artificially limiting yourself to 40% of your battery’s capacity to extend its life seems like an enormous waste of effort

My last phone spent like 8-10 hours a day on and off a wireless charger and had 88% battery health when I sold it over two years after I bought it

I'm pretty sure 88% health means like 80% original capacity since iPhones actually shut off at 20% real capacity to protect the cell.

Assuming that’s correct, by me not janitoring my battery for over 2 years I still have double the capacity of the guy who I originally replied to

I really do not understand how that’s worth “a lot of manual toil”

Apple's "battery health" measure is not the percentage of original capacity remaining. My old iPhone X claims 81% battery health, but the actual capacity is more like 60-70% of original.

I can't imagine caring about my phone's battery health enough to pay attention to not let it charge to 100 overnight.

It's something that should be automated. And even then, I'm not sure I would use it, I usually need 100% of my battery to go through the day.
