watchOS 27, the major update coming to the Apple Watch this fall, includes a useful new feature that could improve the watch's battery life: Proactive battery extension notifications. Apple is preparing to release watchOS 27 this fall. The update brings a new feature called “proactive battery extension notifications” that will improve the battery life of Apple Watch.

Proactive battery extension notifications With watchOS 27, the system will constantly monitor usage patterns of certain functions that require background processing. Apple Watch will automatically turn off the feature if it detects that it has not been used for a long time and send a notification explaining the change. The user will have the option to override the decision and keep the feature on if they wish.

Unused features will be automatically turned off. Features under this automatic roof management system include hand gestures to check the time, a "Raise to Speak" function that allows summoning Siri by lifting the wrist without saying "Hey Siri", and automatic "Start Workout" reminders. While these features may be useful for some users, each of these functions requires the watch's processor to remain partially active and contributes to battery drain even if the user never actually takes advantage of them.

The feature is designed to be invisible to those who regularly use the targeted functions; Warnings will only appear for passive features. Apple doesn't specify exactly how much additional battery life users will gain by disabling these features.
