I have an iPhone 13 mini as my "work phone "and it's indisputably a fantastic, efficient, small phone. However, I am kind of OCD about keeping it between 40-80% charged, which is a lot of manual toil.

Conversely, I also have an Android Galaxy S22+ for my personal phone. The "Battery Protect" feature limits charging to 85%. Life is easy with this device and it causes me a lot less anxiety.

Really now, why can't Apple enable this for older phones? I don't believe there's any good reason to force batteries to excessively damage themselves. I had a previous iPhone 13 mini I was less careful with on the over-charging front, and the battery performance was markedly worse. Hence the OCD. I acknowledge my neuroticism, but try to curb it within the realm of evidence.

For a while I had my phone charger plugged into a smart power outlet and a shortcut to turn that smart power outlet off when the phone's battery hit 80%. It would then turn the power outlet back on at 2pm the next day for it to be ready.

i barely get through the day with a fully charged phone, and i don't get enough runtime if my laptop is not fully charged.

so i'd like to know more about the science behind this. how much does the battery life actually improve by doing this. is the trade off worth the inconvenience of a shorter runtime before i need to recharge?

That's the point. Apple wants other models' batteries to degrade fast so that the users can upgrade to 15

Perhaps they didn't implement this in their BCM, maybe they were so caught up in the cleverness of "optimized" charging they thought it would solve the problem once and for all.

Unlikely? Yes, however it's not impossible.... and not the only alternate explanation :-)

How is that possible? Even charging my phone to 80%, I can still use it for at least a day.

Although my laptop does get a lot more use.

It's for people who only use like 40-50% each day. Going from 50% to 100% puts more strain on the battery than going from 30% to 80%, so limiting the total charge allows the maximum capacity to last longer (in terms of years) than otherwise.

And if you do ever need all 100%, just turn off the limit the day before.

For me it's a no-brainer: 85% on my current (brand-new) Android phone lasts around 50-55 hours.
