Huawei Watch Fit 4

The Huawei Watch Fit 4 features a 1.82″ OLED/AMOLED touchscreen with a resolution of 408 x 480 px and a pixel density of 347 ppi, along with always-on display support for at-a-glance readability. Its physical footprint measures 43 mm in height, 38 mm in width, and just 9.5 mm in thickness, with a total weight of 27 g and a volume of 15.523 cm³, keeping the watch notably compact on the wrist. The band is replaceable at a width of 20 mm, though the display does not use branded damage-resistant or sapphire glass. Water resistance is rated at 5 ATM and IP68, covering submersion to a depth of 50 m, while the watch operates reliably across temperatures ranging from -10 °C to 45 °C and up to a maximum altitude of 164 feet. The device is not designed for kids.

The watch includes a solid array of sensors suited to both everyday health monitoring and active use. A heart rate monitor and pulse oximeter handle continuous cardiovascular and blood oxygenation tracking, while an accelerometer, gyroscope, and cadence sensor work together to capture movement, orientation, and rhythm during workouts. Built-in GPS enables accurate location and route recording without relying on a paired phone, and a compass and barometer round out the navigation and environmental sensing capabilities. The watch does not include a body temperature sensor or a perspiration monitor.

The Huawei Watch Fit 4 covers a wide range of activity tracking functions, logging steps, distance, pace, elevation, and routes during workouts, with automatic activity detection removing the need to start sessions manually. Multi-sport mode is supported alongside exercise tagging, giving users flexibility across different training types, and a dedicated stroke counter is available for swim sessions. Sleep tracking comes with full sleep reports rather than just raw data, and calorie intake can also be logged directly. The watch is not designed for diving or golf specifically.

The watch connects to smartphones via Bluetooth 5.2 and is compatible with both Android and iOS devices. NFC is built in, enabling contactless functionality, and Galileo satellite support extends the accuracy of its positioning capabilities. It does not include a cellular module, Wi-Fi, or ANT+ support, meaning it relies on a paired phone for data syncing and does not operate independently on a mobile network.

The Huawei Watch Fit 4 is equipped with a 400 mAh rechargeable battery rated for up to 10 days of use on a single charge. It supports wireless charging and reaches a full charge in approximately 45 minutes, making top-ups relatively quick. The battery is not removable and there is no solar charging capability.

The Huawei Watch Fit 4 offers a broad set of features centered on health monitoring and daily convenience. On the health side, it measures VO2 max and resting heart rate, provides fast and slow heart rate notifications, flags irregular heart rate patterns, and displays a readiness and recovery level to help gauge overall wellbeing — though it does not include ECG technology or fall detection. Call handling is supported directly from the wrist, with a built-in microphone, call control, and the ability to answer calls, alongside wrist notifications, silent alarm, and vibrating alerts for general use. A stopwatch is also on board, but there is no smart alarm or voice command functionality. The watch includes 4 GB of internal storage, a camera remote shutter function, and a phone-finder feature, while a front camera is not present. It does not support voice commands, and the warranty period covers one year.

The companion app is free and ad-free, and can be personalised with widgets to suit individual preferences. It covers a wide range of health and lifestyle tracking, including calories burned, water intake, weight, and BMI, alongside goal setting, an exercise diary, activity reports, inactivity alerts, and coaching. Women's health features are well represented, with period notifications, fertile window alerts, ovulation prediction, and menstrual cycle start date forecasting all included. Route support, maps, and live tracking are available for outdoor activities, and voice feedback and music playback add utility during workouts. The app does not include a barcode scanner or temperature tracking. Achievements are supported to encourage consistency, and the overall experience is designed to be personalised through widgets and app-level customisation.

The watch includes a battery level indicator, auto pause for workout sessions, and passcode protection for basic security. It is compatible with external heart rate monitors and smart scales, which allows it to integrate with a broader set of fitness accessories. However, it does not support Windows or Mac OS X desktop compatibility, and there is no external memory slot or 3.5 mm audio jack.
