For better autonomy, this connected watch is the model to follow.

Google has detailed the workings of the OnePlus Watch 2’s “hybrid” system. This system will help the company find inspiration for its own watches.

This Monday, OnePlus unveiled its new connected watch, the OnePlus Watch 2, at Mobile World Congress. Unlike the first model, this is a connected watch powered by Google’s Wear OS system. However, the implementation of the operating system makes it the most autonomous model of this type on the market to date.

If OnePlus communicates with an autonomy of up to 100 hours, its own autonomy tests confirmed a usage time of up to 62 hours, which is far ahead of the 52 hours of the Samsung Galaxy Watch 5 Pro and 51 hours of the Galaxy Watch 5 Pro. TicWatch Pro 5. To achieve this result, OnePlus actually uses a hybrid system based not only on Wear OS, but also on an open-source RTOS system, spending much less money. Each system is then powered by its own processor, a low-power model for the RTOS and a powerful SoC for Wear OS.

in Blog posts for developers Among Wear OS applications, Google returns to the system adopted by OnePlus and with which it worked closely with the Chinese manufacturer.

Hybrid system based on two processors

Specifically, the Wear OS publisher welcomes the autonomy achieved by the OnePlus Watch 2 and explains that the watch here uses an operating system that qualifies as:hybrid» — But no mention of RTOS.

If all Wear OS watches on the market, from the Samsung Galaxy Watch 6 to the Pixel Watch 2 via the Xiaomi Watch 2 Pro, feature a two-processor system, there are very few watches with two operating systems. Typically, both processors are used with the same operating system, Wear OS, but for different tasks, as Google reminds us:Wear OS watches feature a dual-chip architecture with a powerful application processor (AP) and a low-power microcontroller (MCU).“. But the architecture of the OnePlus Watch 2 is better.

Wear OS’ hybrid interface intelligently switches between the MCU and AP, allowing APs to pause when not in use to preserve battery life. This helps leverage low-power experiences, for example by analyzing sensor data from the MCU when the AP is in sleep mode. At the same time, the hybrid interface provides seamless transition between the two states to maintain a rich and luxurious experience without sacrificing the transition between these power modes.

Google also cites several examples of the use of these two processors and, in the case of the OnePlus Watch 2, switching from one OS to the other with notifications. When a notification appears, it is handled by a low-power chip. However, if the user wants to interact with it, the application processor is used. The same goes for activity tracking performed by the MCU, or the new watch face format dial (XML) released with Wear OS 4 last year.

A system that can also be found in other watches

Currently, Google is primarily targeting application developers by detailing how this hybrid system works. However, if the company collaborated with OnePlus on development, we imagine it could do the same with other manufacturers like Xiaomi or Samsung. Above all, Google’s own watches, the Pixel Watch and Pixel Watch 2, have regularly been criticized for their poor autonomy. So, we can only hope that the company takes inspiration from the collaboration and integrates the hybrid system into its next watch, the Pixel Watch 3, which could be released in the fall.
