The OnePlus Watch 3 delivers exceptional battery life, lasting up to five days with all features enabled, making it a standout among Wear OS smartwatches. It features a polished design available in two sizes, robust health tracking capabilities, and a dual-chipset power management system.

  • — Sleek and comfortable design with two size options
  • — Robust health features including advanced metrics for sports modes
Watch-outs

How they stack up

Apple Watch Series 11

The Apple Watch Series 11 improves battery life and adds 5G connectivity, but it's held back by the unchanged S10 chip, unlike the OnePlus Watch 3 which uses a dual-chipset system for optimized power consumption. Compared to the Garmin Venu 4, it lacks advanced recovery metrics like Body Battery, and while it offers better software updates than the Apple Watch SE 3, it doesn't match the SE 3's affordability. The Pixel Watch 4 also offers more battery life but without the ecosystem integration that the Series 11 provides.

OnePlus Watch 3

The OnePlus Watch 3 delivers five-day battery life, which surpasses the Samsung Galaxy Watch Ultra 2 and Apple Watch Series 11, but it lacks the advanced health features found in the Garmin Venu 4 and Apple Watch Ultra 3. Unlike the Google Pixel Watch 4, it doesn't include built-in Gemini AI, and compared to the Xiaomi Watch 5, it lacks Wear OS 6 integration and smart features like YouTube Music. The Apple Watch SE 3 offers better value with its updated design and speaker capabilities.
