The Differences Between Fitbit Charge 4 vs Mi Band 5

Which is Better?

Both Mi Band 5 and Charge 4 has got a decent design that’s very lightweight and very comfortable to wear. Also, each of these two is also fitness-focused and can help you stay fit and achieve more fitness goals. However, Charge 4 packs more fitness tracking features in terms of more preset workout modes, the ability to count floors climbed, and has inbuilt GPS that allows you to track outdoor activities without carrying your phone with you which Mi Band 5 lacks. In other words, it’s a better equipped fitness tracker than Mi Band 5.

On the flip side, Mi Band 5 which is far cheaper than Charge 4, is also a comprehensive fitness tracker with the ability to detect an abnormal heartbeat, track your heart rate 24/7, track your sleep in 3 stages; REM, light and deep, and can connect to your phone GPS to enable outdoor activity tracking. It also has a richer and more colorful always-on AMOLED display and has a longer battery life. It’s still one of the most sort-after smartbands at the moment for obvious reasons.
