Redmi Watch 6 NFC Review: Two-Week Battery Life Under $120, But With Caveats

Xiaomi’s Redmi Watch 6 NFC enters the competitive sub-$120 smartwatch market aiming to replicate its past success by balancing hardware capabilities with aggressive pricing. The device boasts a large AMOLED display, a refined design, and the promise of NFC payment capabilities, positioning it as a strong contender for mainstream appeal. However, as a recent analysis from Xataka reveals, the reality of daily use presents a mixed bag of strengths and compromises.

The Redmi Watch 6 NFC offers a compelling package for its price point, particularly in terms of battery life and core functionality. Yet, its closed system and limitations in areas like NFC payments and notification interaction temper its overall value proposition.

Design and Display: A Polished Budget Offering

The Redmi Watch 6 NFC features a 2.07-inch AMOLED display that is bright and clear, even in direct sunlight, with a 60Hz refresh rate contributing to a smooth user experience. The watch’s design is described as balanced and attractive, with a slim profile (9.94mm) and lightweight construction (31 grams without strap) making it comfortable for all-day wear, including during sleep. The aluminum alloy chassis and stainless steel rotating crown add a premium feel, belying its budget price point.

However, the proprietary strap attachment mechanism is a notable drawback, limiting customization options to specific Xiaomi straps. The automatic brightness sensor is also reported to be inconsistent, requiring manual adjustments that are less convenient than a quick-access setting.

Performance and Software: Fluidity with Limitations

Running on HyperOS 3, the Redmi Watch 6 NFC provides a fluid user experience for navigation, animations, and app access. While it operates on a closed RTOS (Real-Time Operating System) rather than a full-fledged OS like Wear OS, Xiaomi’s optimization ensures smooth performance for its intended functions. The companion “Mi Fitness” app is also commended for its user-friendly interface and straightforward setup.

The primary software limitation is the lack of interactive notifications; users can read and dismiss messages but cannot reply, with no predefined responses available. The ecosystem is also restricted to pre-installed apps, excluding popular options like Spotify or Google Maps, and there is no onboard voice assistant.

Health and Sports Tracking: Capable but Not Professional-Grade

For sports enthusiasts, the Redmi Watch 6 NFC offers dual-band GPS for fast and accurate positioning, comparable to more expensive devices. It includes over 150 sports modes, with adaptive display settings that prioritize relevant metrics for different activities. Sleep tracking is reported to be accurate, and SpO2 and stress monitoring algorithms appear well-tuned.

Despite these strengths, the heart rate sensor exhibits a slight lag during rapid changes in intensity, making it less suitable for users who rely heavily on precise heart rate zone training. The absence of a paddle tennis mode is also noted as a personal frustration for the reviewer.

Battery Life: The Standout Feature

The Redmi Watch 6 NFC’s most significant advantage is its battery life. The 550 mAh battery can easily last over 12 days on a single charge with normal usage, and up to 24 days with light use, allowing users to leave the charger at home for extended periods. Even with the always-on display (AOD) enabled, the impact on battery life
