Wear OS 4 has reportedly received a tweak that can significantly improve the battery life of smartwatches that run on Google’s operating system. It will modify how notifications are processed by sending them to a different system, that is expected to improve the device’s battery performance. The OnePlus Watch 2, which was unveiled on Monday at the Mobile World Congress (MWC) 2024, will be the first smartwatch that will support the improved functionality that could arrive on devices in the future. Until now, notifications on Wear OS have been processed and managed by the application processor (AP) which handles tasks requiring more computational processing. As a result, displaying notifications also results in more power being consumed. On the other hand, tasks requiring less power such as step counting and heart rate monitoring are handled by a separate microcontroller unit (MCU). The Verge reports that Google will allow manufacturers to move the notification system to the MCU on Wear OS 4, and that will significantly reduce the amount of battery consumption that occurs when notifications are …
