The OnePlus Watch Series 2 stands out for two compelling reasons. Firstly, it marks a significant leap from its underwhelming predecessor, earning an impressive 4.5-star rating in our OnePlus Watch Series 2 review and securing a spot on our best smartwatches list, surpassing even the Ticwatch Pro 5.
Secondly, its innovative use of dual operating systems allows it to achieve a milestone that no other Wear OS or Apple Watch has reached thus far: up to 100 hours of battery life in smartwatch mode.
This feat is made possible by leveraging a simplified RTOS system powered by a low-power BES2700BP chip for basic functions. When full Wear OS capabilities are required, it seamlessly switches to the battery-efficient Snapdragon W5 chip, optimizing power consumption. This dual-system approach represents a remarkable smartwatch innovation of the year.
