The watch felt lightweight, comfortable and didn’t leave any marks on my wrist. The AMOLED screen is bright, sharp and very responsive. It also features auto-brightness option which is quite handy when on a walk or jog outdoors, especially on sunny days. The brightness automatically adjusts depending on lighting conditions.

When it comes to health tracking, CMF Pro 2 also offers 24 hour heart rate monitoring, oxygen levels monitoring, stress tracking, and sleep tracking. The heart rate tracking is quite accurate when compared with Samsung Galaxy watch 5 and pulse oximeter.

The watch can tracking up to 100 different workouts and offers auto tracking for some of the exercises such as walking, running and cycling. The auto tracking feature is a bit laggy so I recommend to manually start the tracking every time you start an exercise.

The batter life depends on how much you are using the watch and which features you are using the most. On moderate use with 24 hours heart rate monitoring and regular exercise tracking the battery will last for 4-6 days.

Redmi watch 4 also has built-in mic and speaker to make and receive phone calls. I found the call quality to be pretty impressive. The voice was very clear even when my phone was 8-10 meters away from my watch. Only downside is that it does not offers NFC payments option and there is no ability to add third party app the the watch.

Redmi watch also comes as Redmi watch 5 active version which is cheaper alternative for Redmi watch 4. Additionally, Redmi has also released Redmi watch 5 lite version which is premium looking and offers AMOLED display, which is not offered on Redmi watch 5 active version. Even though all three watches run on Xiaomi’s HyperOS and user interface is similar in all three watches, the Redmi watch 4 is the winner of these three due to premium look, metal watch body and higher screen resolution.
