[edit] Working great on iOS 17.
give this feature to older phones, apple. actually be green, not just in your typical BS, like removing stickers, and keep tons of lithium out of our environment. for people who want full charging go for it. for the rest of us, let us prolong the life of the phone. i hate having my phone bake if i am using it for GPS or something else where it has power. there is no hardware limit as we all know and has been discussed in other threads, so it's just a locked software switch and this is BS.
I mean we're talking $99, now $119 for a battery on a $1500 phone (pro max).
I just feel like this is too much thinking for an issue (battery wear which is real) to address. I have mine replaced when they reach 90%, I had my phones around the family and get 5 years out of them, usually need 1 replacement in that time.
This is different than an EV which has a similar thing, but a battery in my EV is over $30k. So yeah, I'm going to be more careful and I follow the manufactures guidance to charge to 85% for regular use.

It’s not a matter of belief. The science behind Lithium-ion batteries is well studied and well understood. The cells degrade exponentially faster at higher voltages (aka state of charge) and temperatures.
Does anyone make a MagSafe 3 in 1 Charging Stand that will charge an iPhone 16 Pro at its maximum wattage and speed?
Apple has introduced expanded charging limit options for iPhone 15 and iPhone 16 models in iOS 18, offering users more control over their device's battery health. This feature, which previously capped charging at 80%, now includes new 85%, 90%, and 95% options.
The system Apple has applied aims to improve battery longevity by reducing the time your iPhone spends fully charged. Apple says the feature can be particularly beneficial for users who frequently keep their devices plugged in for extended periods.
Here's how to use these new settings to potentially extend your iPhone's battery lifespan.
When deciding on a charging limit, consider your daily usage patterns. If you often have access to charging throughout the day, a lower limit like 80% or 85% might suffice. For those who need more battery life between charges, the 90% or 95% options could be more suitable.
- Open the Settings app on your iPhone.
- Tap Battery.
- Select Charging.
- Choose your preferred charging limit from the available options: 80%, 85%, 90%, and 95%.
Remember, you can always adjust these settings as your needs change. If you're planning a long day away from power sources, you might temporarily disable the limit to get a full charge – and if you do, iOS 18 will offer you the option to keep the 100% setting on until tomorrow, or permanently.
Charging Recommendations
In addition, iOS 18 takes this feature a step further by proactively recommending a specific charging limit based on your usage habits. If you have an iPhone 15 or iPhone 16, expect to receive a notification after a while suggesting an optimal charging limit for your device. The recommendation will also appear in the Settings app under Battery → Charging.
It's worth noting that this iOS 18 feature remains exclusive to the iPhone 15 lineup and the upcoming iPhone 16 lineup. Users of iPhone 14 Pro or older models will not find these options in their settings.
Slow Charger Warning
In addition to giving users more charging limits and recommendations, iOS 18 will warn you if you have been using a slow charger.
In the Settings ➝ Battery menu, the battery level graph now shows an orange color where slow charging has occurred over the last 24 hours. If the duration of the charge reaches a certain threshold, a "Slow Charger" warning will appear above the graph. Apple has yet to explain what charging speed triggers the warning, nevertheless it should be a handy detail for users that may still be using old chargers that are no longer up to the task.
Many wireless chargers advertise MagSafe compatibility but only offer Qi speeds or slower. This feature could help iPhone users identify why their devices aren't charging at full speed. However, there's no option to receive an alert when using a slower charger, which would have arguably been a more useful feature, as the battery settings are somewhat buried in the menu.

Yeah... many here believe Apple is always up to something nefarious 24/7.
What's funny is instead of standing up and sending a message to Apple by going with a different tech company, they continue sticking with Apple.
This is a fundamental problem with today’s society. Half of the comments on this thread completely contradict the science of Li-ion batteries (something that has been studied to death, mind you). It is insanity to suggest the opinions from armchair analysts are somehow just as valid as the opinions held by the actual scientists who study the topic.
This is not a topic where opinion is relevant because opinion does not change the science.
I am not contradicting the science of the batteries. Those are known facts. What I find amusing is the amount of effort people put into managing a battery in a phone. A device they will probably not have in 3 years. I have never managed the battery on any of my phones. The batteries have lasted as long as I have owned the phones, which is three years. What happens after that I don't care.
These batteries in the phones are not Tesla battery packs costing 10's of thousands of dollars. These are not Tesla battery packs subject to significant charge and discharge rates that generate enough heat to require active fluid cooling. It is $99.00 to replace my phone battery. Over three years, the longest I have owned a phone, that works out to about $33.00 a year, about $0.09 a day. Hardly worth the time and effort to worry about battery charging.
I sure don't remember this ever existing… but regardless big ups to Al Dente, just a great little app. https://apphousekitchen.com/?utm_campaign=aldente-1.28.2&utm_medium=ahk-url&utm_source=aldente-app
back to the iPhone… the fact that this feature isn't making its way back to older models is my least favorite thing about Apple, arbitrary feature segmentation in software.
$99 and a ton of hassle if you don't live near an Apple Store. Also some of us just don't like waste, in particular e-waste.
The thing is if you aren't draining your battery everyday what have you got to lose by optimising the charging. My phone sits on my desk for most of the day. It would be fine to run it between 20% and 80%, I'd happily do that to get another year out of the battery.
I keep my phones for up to four years. If I can avoid replacing the battery during that time, it's a win for me. It's also easier to sell a phone that has a good battery.
I found a nice calculator for phone and notebook batteries that is based on current research on this topic. There are references, if you're interested. It was recommended on a podcast about battery technology by the way.
You can play with different parameters and see how they influence your battery life. The numbers are not going to be exact, but you can at least get a feeling for the impact of different parameters.
Unfortunately, it's only available in German. But I think English speakers should be able to use it without major issues.

I don't get the need for battery micro management. Just use it and when it gets bad have it replaced. It's not a big deal.
I'll try setting it to 95% and hopefully that keeps the battery healthier. On my 15 Pro I've avoided wireless charging as much as possible and its at 98% health, I think that's helped.
Im thinking of doing the same, doubt it will do anything significant but I definitely end the day with more than 20% so why not see how it goes for a little while.
In fairness, iOS percentage is lower than real battery percentage. Their 80% limit is estimated to be closer to 70-75% of the real capacity, from what some estimates say.
I may set my iPhone 16 Plus (if it has this feature!) to 85% and see if that helps extend the life of the battery.
That's why Apple is one of the most valuable companies in the entire world, its basically a cult at this point..
Most people shouldn’t worry about battery and just should let Optimized do its thing. But on the flip side, many longtime iPhone users have no clue their charger is slow and that iPhones are capable of much quicker charging without notable disadvantages.
People may not realize their old 5W wireless pad or their old 10W iPad charging brick paired with a USB-A to USB-C cable is a dramatically slower experience and sucks when you need to charge quick at a restaurant before resuming your travel etc.
