With iOS 18 have you enabled limit charging on your device?

No. If you’re changing your phone every year or 2, I think it’s weird to limit your battery capacity artificially to 80%, in order to prevent degredation of battery which is likely to be much less than 20% reduction!! In effect, you’re taking a measure which is much worse than the effect you’re trying to prevent
If you’re keeping it for 4 or more years then maybe it’s worth it
Indecently i do limit the charge on my MacBook Pro but only because I use it plugged in most the time and being at 100% a lot degrades it much faster

In my experience in 2 years on average battery life degrades down to 80% depending on your usage pattern.

That’s when you’re supposed to change the battery.

IMO limiting charging on the iPhone is unnecessary.
I charge mine when its around 20%, just in case I run out, and leave it to charge to 100% if I know I'll be out for a longer period then usual. If not, when I notice the battery is above 80% I'll remove it from its charger - I dont actually set it to limit charging - but if I happen to come across it and its above 80% I'll remove it. Otherwise it's going the whole hog.

Not really. I am quite opposite. I like to keep my battery at 100%. I will top up my battery to 100% if chargers available near bye

Three years down the road, the green iPhone 13 Pro is still at 84% battery health.

I never understand the idea of limiting battery from 20%-80%. It is like you only using 60% of possible battery. Some people are willing to spend over $1000 on a new iPhone, but not willing to pay $100 for a new battery.

For me it’s not the battery swapping money that matters, just want to avoid the hassle of wiping the iPhone, taking it to a shop and then setting it up again.

As an annual upgrader, I have the charge limit sets to either 80% or 85%. It doesn't really bother me much as the battery lasts me more than a day.
 
No. Life is short. Batteries are a consumable item. If I need to buy a replacement battery, I can afford it. I don't stop eating when I am 80% full. I don't stop filling my gas tank at 80%. Not going to change those behaviors for a phone.

I set it to 80% the majority of the time. I have a charger within a few feet of me nearly every where I am (car, home, office). If I'm using it heavily I might top it up once during the day (I keep it above 20%).

If I’m going to be out of the house all day I’ll charge it to 100%. I need to keep my phone for at least 3 years and setting it to 80% involves so little extra effort on my part that if it helps to keep my battery running longer at the 3 year mark it’s worth it to me. I’m currently 1 year in and have 97% health with 230 cycles.

The real problem is people often oversimplifying things, leading to a grave misunderstanding. Limiting sustained max charge is only (somewhat) beneficial to select usage patterns, when the device is connected to a charger more than it isn’t. For example, if you have your iPhone as a nightstand and also keep it on a charging stand on a work desk for notifications, etc. For laptop users travel, whether that’s using the computer don’t on their lap or moving from desk-to-desk. Basically, for the most part, as long as the cells are being frequently ‘exercised’ (charging or discharging), battery lifespan (i.e., “health”) is dependent more on environment, especially ambient heat, and manufacturing tolerance luck.

Even better ;) ;) is when they complain about horrible battery life while only utilizing that 60% (or less) capacity range.

Stopping to eat when you're 80% full is actually healthy so that was not a good comparison
Entertaining and a fair analogy, though I’ll expand on it. While (a battery is) most comfortable at ~50% full, if you overeat, then start burning off those calories immediately, the negative impact isn’t going to be big. And successfully pushing an iPhone to burn always those juices is easier than an overstuffed human, ourselves or otherwise. 😆
 
No. I'm not going to gimp my brand new phone to have its battery perform like it's 3 years old.

I use Optimized Charging and charge it to 100% overnight, every night, on a MagSafe stand. I start every day with 100% battery. It usually takes me 3 years to get down to <80%, and 3 years is the longest I've ever kept an iPhone. At that point I'll trade it in, or if I'm going to hang on to it, I'll go get a new battery put in it.

I think you would waste less time and be less frustrated by fully charging your battery and using it without thinking about health every day, and spending 2-3 hours once every 3 years restoring your backup to the new device, instead of worrying every day about charging limit and managing the battery.

It is not so difficult or “frustrating” for me. If I know I need more battery, I charge it up to a 100% without any worries. However, since I can get through my day on about 50-60% of the battery, why charge it to a 100% every day, draining it in a process?

This is what I’m thinking at the moment as well.

I’ve set it to 80% for now and seeing how my days go.

To be honest this is the first time I’m trying this out.

After a while your iPhone should offer you a particular charging limit, based on your individual usage pattern, so you might see a message with a recommended % under your battery settings. Mine says “85%” and marks it in green on the % graph, as below. 🖐️
