Details about the update are still vague — there’s no word on exactly how the feature works, for example — but Google has confirmed to 9to5Google that if a Wear OS watch supports the mode’s requirements (whatever they may be), any Wear OS partner can take advantage of it, and users will see “an improvement in battery life in most situations.” The new low power mode update is launching first on Mobvoi’s Ticwatch Pro, and will eventually roll out to other smartwatch models.
