Xiaomi Mi Band 4 specs and features

The Mi Band 4 is very much a refresh of the Mi Band 3, so it’s not a complete redesign. However, Xiaomi took our biggest gripes with the Mi Band 3 and fixed them in the Mi Band 4.

The Mi Band 4 has a 0.95-inch color AMOLED display. It’s bright enough to see outdoors, and you can even control your smartphones music with it. It’s also the same size as the Mi Band 3, so you can use your Mi Band 3 bands on your Mi Band 4!

Let’s talk specs. The Mi Band 4 has a 5ATM water resistance rating, Bluetooth 5.0 support, and a battery that will last 20 days on a single charge.

It doesn’t have a built-in GPS, though it does have a connected GPS feature for tracking your distance and pace using your phone’s GPS. It also has a heart rate sensor that can hold its own against other wrist-based heart rate sensors.

From a software standpoint, the Mi Band 4 is a nice upgrade from the Mi Band 3. It can now track pool swimming and has a generic “exercise” mode for tracking miscellaneous cardio workouts.
