Display

The Mi Band 3i features a 0.78-inch monochrome OLED touch screen with a display resolution of 128×80. While it supports up to 48 characters, it doesn't display smileys or money symbols.

In terms of activity tracking, the Mi Band 4 is more consistent and offers features like an inbuilt music controller. It also supports a wider range of fitness activities, including swimming with automatic stroke recognition.

Battery Life

Despite having a smaller battery capacity of 110 mAh, the Mi Band 3i outlasts the Mi Band 4 due to its monochrome display and fewer sensors. On a full charge, the Mi Band 4 lasts around 5-7 days with continuous usage, while the Mi Band 3i can last around 10-12 days.

Third-party Apps

One of the standout features of Mi Fitness bands is their support for third-party apps. The Mi Band 3i and Mi Band 4 both have a wide range of third-party apps available, offering additional functionality and customization options.
