I use Automation on my iPhone 14. It announces with a loud spoken text
that 80% SOC is reached. At 90% it commands to be disconnected immediately.

The same on the other side of the spectrum which is much more important
for the expected life of the battery at 20% and at 10%.

BTW I use a 25W fast charger and the iPhone is always somewhere near me.
That makes this strategy very easy. After roughly 2 years the battery
indicates still 100% SOH.

W/o getting into the details, it's like this:

If you're someone who goes a couple days between charging, then the 80% "limiter" is for you. This will lengthen the life of the battery.

If you're someone who frequently can't make it a full day w/o needing a
full charge, then that mode is not for you (this would be people who
actually use the phone function a lot, for example, or who watch a lot
of video or play games when out and about).

I am chagrined that they haven't made this work on my iPhone 11, (iOS
18) - but later models do have the option to select the 80% limit with
the option to bust it from time to time when you know you have a long
day ahead).

That said my iPhone 11 is 5 years old and the batt is fine with a
declared 90% capacity per the battery app.

MacBook Air supports such too (at least the M1 model, not sure about
earlier versions).

I'm using a piece of software called "AlDente" from here:

<https://apphousekitchen.com/>

The basic version will limit charging and allow you to discharge a
battery your preferred level if it goes above for any reason, but I
spent the money for the Pro version with lots of additional options.

Optimized Battery charging needs to be active.

If you leave the computer plugged in a lot, then it will charge to 80%
and hold there unless you force it to 100%. Indeed it will even
discharge from 100 down to 80% according to a website I just looked at.

"Charging on Hold" will display in the pull down from the status bar.

If you're more frequently mobile, then it will always charge to 100%. I believe (like iPhone) this follows the profile of charging to 80%, then
holding and then topping off on time for the habitual departure time of
the user.

Is there a way force recharge to 100% in iPhones like in MacBooks? I didn't see an option for that.

No it doesn't as long as the Mac recognises you are at home.

It is exactly vice versa. It does not work at home. Neither with my MBP
nor with the MBAir.

That stuff is very poorly implemented.

That also applies to the iPhone.

The only time I've seen it active is here at home. OTOH, I don't travel
with that laptop.

That's your use case - in my SO's case, it's usually 80% (but when I
wrote the above, not so - she's been down with Covid so dragging the
laptop unplugged from her desk to kitchen, breakfast table, bedroom ...
this seems to have pushed it into always-charge-to-100 state.

That stuff is very poorly implemented.

That also applies to the iPhone.

I wouldn't say "poorly" implemented but rather "opaquely" implemented
such that it's hard to say what the internal conditions are that drive
the behaviour.

Apple are not much into exposing the conditions or thresholds that would
allow one to tinker with the behaviour.

Turn off optimized charging.

Doesn't that reset the autolearning of usage?

Could be. Apple hopefully continue the learning even if the
