They do on modern iPhones? You can pick: 20% less battery life, and your battery likely won't need to be replaced for 5-6 years, or 20% more and you'll get normal battery longevity.

Also, we're talking in the context of a $1000-1200 phone for the base config. 10% of that cost for a replaced battery does not seem outrageous to me.

As someone else pointed out, the cheaper phones Apple sells have correspondingly cheaper battery repair costs.

You seemed to be arguing that no one needs this feature and it doesn’t need to exist. Not everyone buys the latest iPhones straight from Apple, I’m typing this on someone’s old iPhone 7 and it works fine. The battery life isn’t great but maybe if Apple had implemented this feature earlier it would be better. Replacing the battery would probably cost almost as much as the phone if I did it via Apple.

I'm not sure what you're arguing for here? I'm not aware of any phone that offered a charge limiting option (Android included) 7 years ago. And replacement parts for super old phones remain relatively high in comparison to the value of the device. This is just like cars; at some point it isn't worth fixing/repairing it.

I'm just arguing that having the option to limit battery charge is probably a good idea
