This reminds me of when water bottle companies reduced plastic by 30%.
Of course unlike Nestle and Coca Cola, Apple is too hip to be known for its environmental impact…
The iOS option to charge battery to "80% Limit" shouldn't just be for iPhone 15

I wish they made the batteries slightly larger, then made 100% on the battery meter secretly be 80% of the increased capacity so I could have my cake and eat it.
I would be unhappy if my phone has 20% battery left but I can't make a call or check map/WhatsApp.
I kinda meant on the top end (So it never charges so high that the battery experiences increased wear).
But... this happens at the bottom end too, your battery already still has some charge left at 0%, the BMS protects it from being fully discharged. I'm just wishing there was a bit more so I don't have to make decisions about wearing out the battery faster.
Then I could enable OVERCHARGE and get 120% charge for travelling or when I know it's going to be a long day, at the cost of battery life.

#53Thanks Tesla for bringing about lithium battery health awareness to the masses. Without it I would be charging to 100 every night. And blowing out my battery way too soon.
Arguably, it’s a misfeature of Teslas. My BMW i3 has a hard charging cap of 90%. (The UI scales the charge percentage and displays 100% between 90 and 100%)
It’ll regen charge up to “really” 100%, but that would require something like a 5,000-10,000 ft continuous elevation drop, where you just ride the regeneration brake the whole way down.
Nissan took a different approach. The batteries on the old Leafs died really prematurely because they didn’t have decent battery management.
They fixed it on later models.
Anyway, this stuff is mostly a solved problem these days. It would be nice if device manufacturers were compelled to provide an 8 year, 80% capacity parts and labor warranty on all non-replaceable batteries (like the car manufacturers do in the US).

#54I have an 11 pro as my main workhorse. Multiple years old, constantly running the battery to 2 % then charging to 100 and it still lasts all day for me. I feel like the concern I see going on in this thread might be a bit misguided.

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.
I wish they made the batteries slightly larger, then made 100% on the battery meter secretly be 80% of the increased capacity so I could have my cake and eat it.
They almost certainly aren’t driving them to 100% physically possible, just like they aren’t draining them to absolute zero.
The cutoff points are going to be picked to balance lifespan and capacity.

iOS already does something like this. After the phone turns off from low battery, it’ll still allow you to use Apple wallet for a few hours.

#57That's the point. Apple wants other models' batteries to degrade fast so that the users can upgrade to 15
Do you have anything other than context clues to go by when making this assertion?
These discussions are always baseless.
Could Apple have enabled this feature for all phones? Maybe
Would it have provided any use to older phones? Maybe
How much lifespan does it actually add? No one knows
Did they do this as planned obsolescence? Maybe.
There we go, the whole discussion finished.

#58I 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…
I just use my phone. The battery can be replaced.
Sure, as long as you don't mind messing up / sacrificing the IP69 waterproof seal integrity.
Ask me how I know *cries softly*.

#59On my 13 mini, I just set a shortcut to turn on power save mode when power save mode is turned off. I also set a geofence around the cell dead spot at my house to enable airplane mode. The latter spams notifications due to an (anti-stalking?) “feature” of shortcuts that doesn’t let you disable geofence notifications. That bug can then be fixed by exploiting another bug by enabling screen time, the creating a custom a…

How?

#60Glancing at some comments here mentioning the overnight charging feature working for them, am I in the minority by charging randomly whenever it needs it? My charger isn't even in the bedroom. Curious how my random on/off habits compare to overnighters in long term battery health.
I try to take it off around 80% so I was interested in this feature and confused when the update didn't include it. I don't like that it's in my "pros" column for upgrading when it could be available to everyone, would rather not reward them for that.
