Google announces a revamp in the architecture of the Wear OS 4 operating system to support a dual-chipset configuration, which is now utilized in the OnePlus Watch 2 launched today.
The Wear OS strategy by OnePlus (and likely other brands to follow suit) incorporates two chips – the main application processor (AP) and the energy-efficient microcontroller unit (MCU) to manage varying processing needs. The goal is to extend battery life significantly.
Google has redesigned Wear OS to facilitate seamless switching between the two chips for tasks that require minimal processing power, such as displaying watch faces, receiving notifications, and collecting data from health-fitness sensors. This transition helps conserve energy. However, when users engage in more demanding tasks by interacting with the screen, the operating system automatically switches to the main AP chip.
Google states that Wear OS will autonomously handle chip switching, requiring developers to utilize standard system APIs like Notification API, Health Services API, and the XML-based Watch Face Format for customization.
TLDR: Google upgrades Wear OS 4 to support dual-chipset architecture for more efficient processing and improved battery life in devices like the OnePlus Watch 2.
