OnePlus Watch 2 launched globally: A Wear OS smartwatch with over 2-days of battery life

The OnePlus Watch 2 comes with a unique dual architecture system that runs Wear OS and RTOS side-by-side.

  • OnePlus has launched the new OnePlus Watch 2 globally. You can buy the Watch 2 in the US for $299.99 from March 4, 2024 onwards from Amazon and
  • OnePlus is also offering a $50 discount when you trade in any watch in any condition when purchasing through
  • Key specifications of the OnePlus Watch 2 include Snapdragon W5 Gen 1 SoC, BES2700 co-processor, Wear OS 4 support, 500mAh battery, 47mm size, IP68 protection, and more.

OnePlus entered the smartwatch space with the first-gen OnePlus Watch. But the company oversold the “smart” in smartwatch, as the first-gen device ran on a simpler RTOS platform without an app store. Three years later, the company is back with a true smartwatch with Wear OS, but surprisingly, it isn’t letting go of RTOS either. This is the OnePlus Watch 2, and its unique dual-architecture setup and massive battery help it become the Ultra smartwatch on the Wear OS side of things.

The highlight of the OnePlus Watch 2 is certainly its dual-engine architecture. It comes with the Qualcomm Snapdragon W5 Gen 1 chip alongside a BES2700 co-processor. The Snapdragon powers Wear OS 4 on the watch, while the co-processor handles RTOS functionality in power-saving mode.

You can run the watch in Smart Mode with full Wear OS features and all smartwatch functions or run it in a power-saving mode where it works like an RTOS fitness tracker with access to health tracking functions and your phone’s notifications (but no Wear OS app functionality).

OnePlus went even crazier, packing this large 47mm diameter smartwatch with a 500mAh battery. In Smart Mode, you can get up to 100 hours of battery or over 48 hours with heavy usage and all features enabled. You can also get over 12 days of battery life in power-saving mode with RTOS functionality.

As we note in our OnePlus Watch 2 review, the watch lasted us 53 hours on a single charge in Smart Mode, with the always-on display and all advanced health features enabled and many workouts packed in.

The OnePlus Watch 2 charger features a removable USB-C cord.

If you run out of juice, you can charge the smartwatch to 100% in 60 minutes with 7.5 VOOC fast charging. The watch charges through a magnetic cradle, and unlike many other smartwatches, the cradle plugs into a standard USB-C port, so you can continue using the cable you use with your USB-C smartphone.

The OnePlus Watch also supports tracking for over 100 sports and can track health stats like sleep, stress levels, blood oxygen, and more.
