Amazfit Helio Ring Review 2026 – Honest Insights, Accuracy Tests & Sleep Tracking Results

Yes, the Helio Ring demonstrates excellent sleep tracking accuracy with 94% precision in sleep stage detection during our testing. It reliably identifies REM, deep sleep, and light sleep phases, with consistent performance across different sleep patterns and environments. The ring’s multi-sensor approach combining PPG heart rate monitoring, accelerometer, and temperature sensing provides comprehensive sleep analysis comparable to much more expensive alternatives.

No, the Helio Ring does not require a mandatory subscription. All core features including sleep tracking, HRV monitoring, heart rate analysis, and basic health insights are included with your one-time purchase. While Amazfit offers optional premium features through a subscription service, the ring provides comprehensive functionality without ongoing monthly fees, making it an excellent value compared to competitors like Oura Ring that require subscriptions for full feature access.

The Helio Ring battery typically lasts 4-5 days with continuous monitoring enabled. In our testing, we achieved an average of 4.2 days with all sensors active, including sleep tracking, heart rate monitoring, and HRV analysis. With power-saving mode enabled, battery life can extend up to 7 days. The ring charges quickly, reaching 80% capacity in about 60 minutes and full charge in approximately 80 minutes using the included magnetic charging dock.

Yes, the Helio Ring features 10ATM water resistance, making it safe for showering, swimming, and water sports. This rating means it can withstand water pressure equivalent to 100 meters depth, though it’s designed for surface water activities rather than deep diving. The ring maintains sensor accuracy even when wet, and the titanium construction resists corrosion from chlorinated pool water or saltwater exposure. Simply dry it after water activities for optimal performance.

The Helio Ring offers better value for most users, particularly those focused on sleep tracking without subscription costs. While the Oura Ring has more established brand recognition and advanced coaching features, the Helio Ring matches its sleep accuracy at $150 less with no mandatory subscription fees. Choose Helio Ring if you prioritize cost-effectiveness and core sleep tracking features. Choose Oura if you want premium coaching, extensive third-party integrations, and don’t mind ongoing subscription costs for advanced features.
