iOS 18 Introduces More Charging Limit Options on iPhone 15 Models: 85%, 90%, and 95%

All four iPhone 15 models feature a setting that prevents the devices from charging beyond 80% while toggled on, which can potentially improve an iPhone battery's lifespan by reducing the time that the battery is fully charged. And with iOS 18, Apple has taken this feature a step further by adding new 85%, 90%, and 95% charging limit options.

The feature can be found in the Settings app under Battery → Charging.

The charging limit feature remains exclusive to the iPhone 15 lineup on the first iOS 18 beta, with the option not found on the iPhone 14 Pro or older.

The first iOS 18 beta is now available for Apple Developer Program members, and a public beta will follow in July. Following beta testing, the update should be widely released to all users with an iPhone XS or newer in September.

there is no hardware reason this cant be added to *any* iphone supporting this OS. programming the charge controller has been around forever. this is simply locked out for older models for marketing. please don't restrict this to only 15+. I hate having to keep killing my battery when it is docked for GPS functionality or even just watching a movie or something when power is available.

Surprised Apple didn't make this feature limited to iPhone 16 series and up to get people to upgrade.

Algorithmic charging requires some intelligence to run efficiently and reliably. This tech is built into the latest and greatest iPhones.
It isn't an algorithm. Optimized Battery Charging which "intelligently" delays charging past 80%, is available even on iPhone 6S. This latest Charging Limit feature is about as basic as it gets.

Yep, jailbreak confirms the feature is hidden behind a simple toggle. Some people have enabled it on iPhone 11.

It's more complicated than you think. It doesn't just charge to 80% and stop, it slow charges as well based on algorithms of your previous use patterns. Slow charging is another battery-extending safety measure.
Are we just making up stuff now? Somehow, Optimized Battery Charging doesn't "slow charge" when the device hits 80%?

Anyway, the jailbreak already proves Charging Limit to be purely feature rationing by Apple. When toggled on, it works completely fine on iPhone 11 through 14.
