With watchOS 9 on the Apple Watch Ultra, Apple introduced a new battery feature called Optimized Charge Limit, which uses on-device machine learning to analyze your daily usage and dynamically set a maximum charge limit for your watch.

Available now as a developer beta and coming to all users later this year, watchOS 10 will extend this Optimized Charge Limit to additional Apple Watch models, including Apple Watch SE, Series 6, Series 7, and Series 8. Any new models released later this year alongside the public release of watchOS 10 will undoubtedly also support the feature.

Optimized Charge Limit is an extension of the Optimized Battery Charging feature that waits to fully charge your battery until just before your device expects you to need your Apple Watch, in order to limit battery degradation due to overcharging. Optimized Charge Limit augments this by predicting how much battery life you are likely to need on any given day and only charging up to a level sufficient for your expected needs.

As a result, on some days your Apple Watch may charge all the way to 100%, while on other days it might charge to only 80% or 90%. The feature is optional but on by default, and it only engages in locations where you spend a lot of time such as at home or at work, recognizing that less frequently visited locations are more likely to have unpredictable impacts on your watch usage and charging patterns.

You can also manually override a planned Optimized Charge Limit by tapping the open charging icon after connecting to a charger and selecting the "Charge to Full Now" option.

For more details on how to manage Optimized Charge Limit, check out our how-to on the feature.

I'm not convinced it works correctly on the watches that are out now. It once worked on my ultra, but haven't seen it in months. Maybe they could include a little more user control??
 
Am I the only one that thinks this sounds terrible? Thanks for the heads up. Definitely turning it off by default! 😂 I want 100% each day thanks..

Yeah, same boat. My watch is already not at 100% sometimes when I need to go, and that’s after leaving it on the charger overnight. If you wanna slow it down at 3-4AM, fine, I’m probably sleeping, by 6AM clock that thing better be at 100
 
I am pleasantly surprised by Apples backwards compatibility this year. Old Apple would have made things like this and and Standby mode „recent mode exclusive instead my Series 6 and iPhone 12 Pro Max gets all the new features!

I guess Fall 2024 will be the time to finally upgrade both
 
I've seen the optimized charge limit a few times on my Apple Watch Ultra. But I have no idea what logic it uses to decide when to use it.

Does anyone?
 
Mine worked only once. One time I forced it to charge fully and that's it, it always charges to 100%. Why can't they put an option to set charge levels. Or allow app like Aldente in iOS and watchOS.

An excellent feature to extend battery life. Options are good. This should be extended to all devices to set a charge limit.
I myself use an AppleCare incident to get a new device + battery.
Gonna enjoy unlimited claims while it lasts.
 
This also seems to be the end for feature parity between watches.
The S6 chipset devices get this, the series 5/4 20% slower CPU didn’t make the cut.
 
I love this feature. It works flawlessly! Please bring this Optimized Charging feature to iOS 17.
Isn’t it already there for the phone? If you meant iPad OS then I am all in on that.

I want optimized charging on the iPad. My iPad mostly sits on a table plugged in most of the time. It doesn’t need to stay jammed to 100% charge 24/7.
