Technical Details
Product Discription:
Mi Smart Band 4 is an affordable fitness band from Xiaomi. With this, the fourth iteration of the Mi Band, Xiaomi has introduced a colour display and swim tracking, and still claims to offer 20-day battery life. The Mi Band lineup began with a product that didn't even have a display and now we get a device with an AMOLED colour display and lots of watch faces, which are nice to have. The Mi Smart Band 4 costs a little more than the Mi Band 3, but are its new features worth the asking price? We used it for a week to find out.
Mi Smart Band 4 design
The Mi Smart Band 4 has all its electronics in a plastic capsule that fits snugly into a silicone band. The display is on the capsule, and a single capacitive button is below the screen. The base of the capsule has the heart rate sensor and pins for charging. To charge the Mi Smart Band 4, you need to take the capsule out of the band and place it in its charger.
Mi Smart Band 4 performance and battery life
The Mi Smart Band 4 has a lot of useful features such as the ability to track different types of workouts including swimming, sleep tracking, continuous heart rate monitoring, and notifications are displayed too. Our biggest problem with this device was that most of the useful features were disabled by default and we had to manually enable them in the app.
Mi Smart Band 4 companion app
We've always appreciated the quality of the Mi Fit app and often noted how it's much better than the companion apps for several fitness bands priced higher than Xiaomi's Mi Band lineup. Our thoughts on the Mi Fit app remain largely the same even now. We think it looks good, and largely makes it easy to find the data you need. A couple of data points, such as historical data for exercise and running, were slightly hard to find because they weren't in an obvious spot. However, this is a minor quibble.
