The Redmi Watch 5 Lite features a 1.96″ OLED/AMOLED touch screen with a resolution of 410 x 502 px and a pixel density of 331 ppi, and it supports an Always-On Display mode. The case measures 49.1 mm in height, 40.4 mm in width, and 11.4 mm in thickness, with a total weight of just 29.2 g and a volume of 22.61 cm³. It comes with a replaceable 22 mm band, though it does not feature branded damage-resistant glass or sapphire glass. On the durability side, the watch carries a 5 ATM rating and an IPX8 ingress protection rating, making it water resistant to a depth of 50 m.
The watch includes a heart rate monitor and a pulse oximeter for continuous cardiovascular and blood oxygen tracking, alongside an accelerometer and a gyroscope for motion sensing. It also has built-in GPS for location and route tracking. However, it does not include a body temperature sensor, compass, barometer, or perspiration monitor.
The watch covers a broad range of activity tracking capabilities, including steps, distance, pace, and calorie intake, along with automatic activity detection and exercise tagging. It provides sleep tracking with detailed sleep reports, and a route tracker is available for outdoor sessions. Multi-sport mode and a swim stroke counter expand its usability across different disciplines, though it is not designed for diving or golf and does not track elevation.
The watch connects to smartphones via Bluetooth 5.3 and is compatible with both Android and iOS devices. It also supports the Galileo satellite navigation system for location tracking. It does not include a cellular module, Wi-Fi, or NFC, so all data syncing and communication rely on the Bluetooth connection.
The watch is powered by a 470 mAh rechargeable battery with a rated battery life of up to 18 days. The battery is not removable and does not support wireless or solar charging, meaning it requires a wired connection to recharge.
The watch supports call answering and call control directly from the wrist, backed by two built-in microphones, and also responds to voice commands. Wrist notifications, vibrating alerts, and a silent alarm keep the user informed throughout the day, while a stopwatch rounds out the everyday utility features. A phone finder function and a camera remote shutter add further convenience, and resting heart rate monitoring is included. On the other hand, the watch does not offer ECG technology, irregular heart rate warnings, fall detection, VO2 max measurement, or a smart alarm. It comes with a 1-year warranty.
The companion app is free to use and requires an account to get started. It covers a wide range of tracking and management tools, including calorie burn, water intake, weight, food diary, and exercise diary, with support for 160 exercises and route tracking. Activity reports, inactivity alerts, goal setting, achievements, and coaching features support an structured approach to fitness, while music playback and widgets add everyday utility. The app also includes a full suite of women's health features, covering period notifications, fertile window notifications, ovulation prediction, and start date prediction. Personalisation is supported, but the app does not offer temperature tracking, calendar sync, email export, or a barcode scanner.
The watch includes a battery level indicator and is compatible with external heart rate monitors, adding flexibility for users who prefer dedicated chest straps or other accessories. It does not support passcode protection, and there is no external memory slot or 3.5 mm audio jack. Regarding desktop compatibility, the watch does not work with Windows or Mac OS X systems.
