watchOS 10 will bring Optimized Charge Limit, as seen on the Apple Watch Ultra, to older Apple smartwatches. The feature debuted with watchOS 9 but was only available for the Ultra wearable.
Optimized Charge Limit is different from Optimized Battery Charging. However, both features aim to extend the lifespan of your Apple Watch’s battery.
watchOS 10 will extend your Apple Watch’s battery lifespan
With Optimized Charge Limit, your Apple Watch will use machine learning to analyze your usage. Based on that, it will charge your wearable’s battery to a certain level instead of topping it to full. This feature will dynamically adjust the charge limit based on your usage pattern.
For example, if you go for a run on weekends, your Apple Watch will charge 100% to account for the battery drain. On weekdays though, the watch will only top up to 80 or 90%. The feature only works in specific locations, like your home or office, and won’t trigger when you are traveling.
watchOS 10 will bring Optimized Charge Limit to Apple Watch SE, Series 6 and newer models. Series 5 and older models are not compatible with the feature.
Optimized Charge Limit is enabled by default
Optimized Charge Limit will not work immediately on your new Apple Watch as it takes time to learn your usage patterns. The feature is enabled by default and does not require any user intervention.
A Charge to Full Now option will appear on your Apple Watch’s display when the feature is active. This will allow you to bypass the charge limit when needed. Or you can jump into the Settings menu of your watch to turn off the option entirely.
watchOS 10 lands in September this year. But if you cannot wait, you can download and install the watchOS 10 beta on your Apple Watch today itself.
