OnePlus Watch 2 and 2R Users Face Battery Drain Issues After Wear OS 5 Update

In a setback for users of the OnePlus Watch 2 and 2R, the much-anticipated Wear OS 5 update, rolled out towards the end of December 2025, has been causing severe battery drain issues, reducing the device's battery life from the promised three days to just one or two days.

Battery Drain Issues

Several OnePlus Watch 2 and 2R users have reported that the update has led to significant battery drain, causing the device to plummet from full charge within a day on light usage. This has left users "heartbroken and frustrated," according to one user on Reddit.

System-Wide Issue

Users have pointed to various apps as the culprits, such as the Weather app, Play Store, or "Wear OS" itself. However, the diversity of apps causing drain suggests this is a system-wide issue rather than one app causing problems.

Impact on North East Region

The battery drain issues faced by OnePlus Watch 2 and 2R users are a concern not only for users in India but also for those in the North East region, who have been increasingly adopting smartwatches for fitness and health tracking. The reduced battery life of these devices may affect their usefulness, particularly in areas with limited charging facilities.

Implications for OnePlus

The unoptimized update on last-gen models has been disappointing to see, especially considering that the OnePlus Watch 3 has run Wear OS 5 since April without issues. OnePlus needs to address this issue promptly to regain users' trust and prove that its promises of two Wear OS updates and three years of security updates are not empty rhetoric.

Conclusion

OnePlus's Wear OS 5 update for the OnePlus Watch 2 and 2R has led to severe battery drain issues, causing frustration among users. The company needs to address this issue quickly to maintain user trust and ensure the longevity of its smartwatch offerings in the North East region and beyond.
