Xiaomi Mi Smart Band 8 vs 7: General and hardware


In terms of design, the Xiaomi Mi Band 8 looks very similar to the Mi Band 7. Both fitness bands have a rubberized practical look that is unmistakably focused on fitness tracking.

The Mi Band 7 features a 1.62-inch display with a resolution of 192 x 490 pixels, 326 ppi and a maximum brightness of up to 450 nits. The display is covered with tempered glass, which gives it an elegant and impressive appearance. The display’s edge-to-edge design means there’s no room for a physical button, so users have to rely on the touchscreen and gestures to navigate menus.

Xiaomi decided to keep the same display size for the Mi Band 8. No change and you still have the always on option for some watch faces. It would be pointless to increase the screen size as it is very large. However, the aspect that has improved is the maximum brightness that the bracelet can achieve, which for the first time exceeds the brightness of 600 nits to approach the level of a smartwatch. The refresh rate has also been improved to 60 Hz.

A notable change is that the Xiaomi Mi Band 8 offers a two-piece detachable band and a new band connection. Its predecessor has a one-piece strap that allows users to pull the main unit out of the strap. This new design feature allows for more versatile and handy strap combinations. Users can even wear the band as a necklace or tied to their shoes.

Xiaomi has developed an easily removable strap mechanism that allows you to change the straps every day according to your mood or occasion. The diverse selection of straps available includes gin leather, woven straps, double leather and hollow bracelets. A pendant style option is also available.

Overall, while the design changes in the Mi Band 8 may seem minimal, the two-piece detachable band is a notable improvement. The design remains functional and affordable, while the new strap mechanism allows for greater customization and wearability.

Under the hood

The excellent 5 ATM rating and swim-proof design remain the same. As well as sensors.

The company hasn’t mentioned any improvements to the underlying technology, but it’s quite possible that there have been slight improvements.

Battery life

Next up is very important battery life. This has always been an important selling point of Mi Bands.

We are happy to report that the 8th iteration does not disappoint in this regard. The predecessor works for 15 days on a single charge thanks to a 125 mAh lithium-ion battery.
