What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Heart rate accuracy during workouts is substantially better than the previous model, tracking closely with a chest strap across walks, bike rides, and high-intensity sessions.
- The haptic side button restores easy navigation and performs as well as a physical button in daily use.
- Built-in GPS delivers reliable route tracking, with distance closely matching dedicated sports watches.
Reviewers push back
- Music controls are locked to YouTube Music Premium, leaving users of other streaming services without any remote control.
- Heart rate broadcasting uses proprietary encryption incompatible with most third-party apps and bike computers, making the feature unreliable outside a narrow set of supported platforms.
- Battery life falls well short of the seven-day claim under real-world use with GPS, always-on display, and sleep tracking active.
A capable fitness band with meaningfully improved heart rate accuracy and useful Google integrations, let down by locked-down music controls and a fragmented subscription ecosystem.
On Charge 6: DC Rainmaker found the heart rate broadcasting pairing process unreliable and frequently broken, while Wearable Whisperer completed a full cycling session with no connectivity issues at all.
