yes it did, and does. the optimized mode is based on routine. when i am in a regular work routine it always worked for me. it is simply a software toggle

It's great that it works flawlessly for you. Apple has improved it regardless, and no longer supports the method you think is perfect versus masses of analytics data showing otherwise.
 
This slider should go below 80%, but Apple doesn't want your battery lasting for years/decades, like a Tesla.
 
If anyone wants this for their Mac, there's an app called Al Dente that adds this, I've been using for well over a month now. A+, exceptionally well done.

Hoping this comes to Sequoia and new iPads, though.

Yeah, I use AlDente and I like it a lot. It isn't always accurate/reliable for me (set limit at 55 and it charged to 69 today), it is often going to be off by a few points but it doesn't matter.
 
I know some people will think “whats the point“ but I really like Apple’s push to introduce limited charging options. I charge my 15 Pro Max to 80% every night as I don’t need the full capacity, and after 9 months my battery health is going strong at 98%. Hopefully this comes to the watch very soon
How many cycles do you have? I’ve never used the feature since release and i’m at 98% with 280 cycles. I use magsafe charging every night as well with all the added heat lol.
 
Same reason why iPhone 13 doesn't get Photonic Engine even though it uses the same A15 as iPhone 14.

Or iPhone 15 gets Smart HDR 5 while iPhone 14 Pro/Max stays with Smart HDR 4. Both use A16.

Feature rationing means when existing iPhone users upgrade, they'll be wowed by a greater number of new features.
Or the 15 getting the 24mp photo option while the 14 Pro/14 Pro Max with the same A16 doesn’t get it.

It is not active when it is not running. So while rebooting or when macOS is shut down the macbook will charge until 100%.

It's nice that this feature is available to those who want to use it.

To be completely honest, being at 100% in the morning, using it all day without plugging in, and not having to obsess over managing the battery is worth the cost of getting a battery replacement every couple of years.

Awesome. I typically use 80% charging, but sometimes I think 85% would be better for me, and it will be nice to slowly increase as the battery ages (and iOS versions get more battery hungry).
 
My first thought was that this is too many choices. Un-Apple-like. What's the point?
You can start low and ramp up as the battery degrades over the years, instead of it being only on or off. One user might get through the day with just 80% while another needs 90%.

I charge my iPhone 15 Pro to 100% every night. After 9 months my battery health is going strong at 100%. I just let the phone worry about the battery. Seems to be working.

Seems like a job for Apple Intelligence.

Wasn't aware of that little gem and I looked for something like that when I made the move to Mac. I would still have been using my MBP if I knew. Yupp, busted it. This functionality is fairly basic though, and coming from decades with ThinkPads, it was close to top of the list for initial setup bot for Win and Linux, setting both the "commence charging" and "do not charge" threshold. Makes A LOT of difference as I prefer 32" to 15". Never understood why Macs didn't provide that feature.

I could make good use of it for my iPhone too - using it regularly as a modem, and the "commence charging" would have been useful too, allowing it to drop a suitable percentage before charging kicking in. Guess that would have been somewhat different though. A Thinkpad or a Mac would run getting energy from the grid leaving the battery alone for ages. Not sure if iPhones works that way, "bypassing" the battery when plugged in.

3 things I miss on MBPs compared with Thinkpads: Charge control, integrated cellular, and the red knob.
 
I'm somewhat surprised that Apple is providing such granular options. It feels like after getting analytics on trillions of charge cycles, they'd have a pretty good idea of the number that works best for preserving battery health for 99% of users. That said, maybe they don't actually have that data, and they're letting users pick a charging percentage now and collecting data to see what works best.
 
locking away features like this just pisses of loyal customers. I had a JB iphone 7 on ios 13 that was able to do this, so every damn phone from at least that on can definitely do it. it is a basic feature of a lithium ion charge controller, so i would venture to guess even older iphones than that could if the software switches were available...LOL.

It's a dumb marketing move to restrict this, because no one will rush out and upgrade for this one small nicety, but it would make current customers happy to have this option unlocked and make them more likely to be loyal to apple in the future, whereas locking it for marketing just pisses them off (death by a 1000 little cuts so to speak).

It may be silly, but I get angry when i have a phone continuously charging in the car at 100% because I am using the music and/or gps and having it heating up for absolutely no reason. particularly when many androids and laptops have had this feature forever. the heat and overcharging is bad for the phone electronics, the battery and just really bad for the environment. all these battery packs just end up in landfills polluting the water table, when they probably could last twice as long for the majority of normal users.

green company my @#$@! be green and let all the phones do it - use that for marketing instead - a win for everyone.

In the last year I upgraded my iPhone X to an iPhone 15 Pro Max. My favorite new things aren't the cameras or the speed or the weatherproofing or even the bigger screen. It's the bigger battery combined with the new 80% charge limit feature. The Pro Max battery is big enough that I can keep the charge limited and still end pretty much every day with 20%-30% battery remaining. It's really great to not a) run out of juice or b) have your battery life nosedive after a couple years because it's been thrashed by daily charge cycles. I still have to verify the second one, but I'm assuming it will be better (towards the end I was having to charge my iPhone X 2-3 times a day).
 
Do you have evidence there are no hardware differences on the newest iPhones that would limit this to them? It’s extremely rare Apple would limit something like this purely by software. The question is if you can provide an example of Apple ever limiting a feature to the newest device without some hardware reason for it.

This means it is very possible there is hardware that’s involved in controlling this that is not available on older iPhones.
Correct me if I am wrong, but didn't this just happen with the new M3 Macs? With a software update they were magically able to display 2 screens instead of one?
