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.

Xiaomi Watch 5
Ranked #8 in Best Smartwatches
Xiaomi Watch 5
8 sources2 derived

The Xiaomi Watch 5 stands out as one of the best Wear OS smartwatches available, thanks to its integration of Wear OS 6 and a significant battery upgrade with silicon-carbon technology that delivers up to four days of usage. Reviewers praised its 1.54-inch AMOLED display and smart features like YouTube Music and remote camera control. However, some noted the lack of wireless charging and that the build quality, while solid, doesn't quite match premium offerings. This makes it ideal for users seeking long battery life and Android smartwatch functionality, though those prioritizing premium feel may want to consider alternatives.

Strengths
  • — Features Wear OS 6 integration which improves software experience
  • — Includes silicon-carbon battery technology delivering up to 4 days of battery life
  • — Has a 1.54-inch AMOLED display with 2.6 mm thickness
Watch-outs
  • — Charger is not wireless and uses a proprietary two-pin charging port
  • — The design is somewhat plain and lacks standout style.

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.

The Google Pixel Watch 4 offers more battery life but lacks the Android smartwatch functionality.
