Companion Apps

To analyze your activities, the Xiaomi Mi Band 6 uses the Zepp Life app while the Fitbit Charge 4 uses the Fitbit app. I find the Fitbit app more user-friendly than the Zepp Life app.


The Fitbit Charge 4 and Xiaomi Mi Band 6 have SpO2 sensors, PPG Heart Rate monitors, an accelerometer, and a gyroscope. The gyroscope measures orientation while the accelerometer measures the linear acceleration of your watch. The PPG Heart Rate sensor tracks all heart activities while the SpO2 sensor monitors your blood oxygen level.

If you’re looking for a watch to track your swimming, Fitbit Charge 4 and Xiaomi Mi Band 6 are option.

The Fitbit Charge 4 automatically monitors your swim lengths, duration, total distance, and pace. It also has 20 sports modes, including cycling, running, swimming, walking, and outdoor and treadmill workouts.


Both the Fitbit Charge 4 and the Mi Band 6 are waterproof watches that can resist water up to a depth of 50 meters. This makes them perfect for activities like swimming and showering without worrying about water damage.

Location Tracking

Both watches have GPS connectivity, allowing you to monitor your routes and paces. However, it’s worth noting that the Mi Band 6 uses connected GPS, meaning you will bring your smartphone along to use GPS. On the other hand, the Charge 4 has a built-in GPS, which eliminates the need for a phone.


The Mi Band 6 is a small device that offers several useful features. It provides smart notifications for incoming calls, emails, and text messages, among other things. You can reject incoming calls if you don’t want to take them.

On the other hand, the Charge 4 can also connect to your phone and provide notifications for incoming calls, app updates, meeting alerts, and text messages. However, the level of interaction with these notifications is limited.

Battery Life – Xiaomi Mi Band 6 Vs Fitbit Charge 4

When considering which exercise smartwatch to purchase, it’s important to take note of the battery life. Battery life refers to how long you can use the watch before it needs to be recharged.

The good news is that both smartwatches we are looking at today have impressive battery lives. If you opt for the Xiaomi Mi Band 6, you can enjoy up to 14 days of battery life on a single charge. On the other hand, if you choose to buy the Fitbit Charge 4, you’ll have up to 7 days of battery life on a full charge.

As you can see, the Xiaomi Mi Band 6 has double the battery life of the Charge 4, but 7 days of continuous use is still a decent period. Therefore, we believe that both watches are worth investing in.

Lastly, it’s important to note that, like any other smartwatch on the market, using GPS will significantly reduce battery life. For instance, using GPS on the Charge 4 will give you about 4 hours of use.
