The display has undergone the biggest innovation
Even though we have the weight listed as the first item in the table, the difference of two grams is really negligible. According to the available information, the dimensions have not increased either. The body of Mi Band 4 should also be able to be used with a bracelet from Mi Band 3. However, the most significant innovation is the display.
In the new Mi Band 4, a color AMOLED touch screen was used. In addition to its predecessor, it has grown and has diagonal 0,95 inches. The OLED black and white display in the older Mi Band has a diagonal of 0,78 inches. The resolution has also changed from 80 x 128 pixels to 120 x 240 pixels.
It's not just about size and colors
However, it is important to write that the manufacturer cared about the clear display. For both the older Mi Band 2 and Mi Band 3, many users had difficulty reading displays in direct sunlight. With a new bracelet with AMOLED technology used, everything should be different. The brightness level can be adjusted by the user. The curvature of the 2,5D display only adds to its attractiveness.
The display is therefore larger, more colorful, softer and clearly legible. It can display more information than its predecessor. The user can choose from up to 77 different dials and more will definitely increase. That was not possible in the older bracelet.
Improved connectivity
Bluetooth has also been released. Upgraded from the original 4.2 for Mi Band 3 to version 5.0. The renewed technology guarantees a faster and more stable connection with the phone.
A few extra sensors
Another significant change is the use of sensors. The Mi Band 3 is equipped with a 3-axis accelerator and a heart rate sensor. In addition to these two sensors, the newer bracelet also has a 3-axis gyroscope and a capacitive proximity sensor.. It logically follows that Mi Band 4 should monitor more accurately especially physical activity.
In this comparison, we will not describe all the features of the new or older Mi Band. We described all the specifications in the article on the introduction of the bracelet. We will only list those that the older Mi Band 3 does not have.
Mi Band 4 can recognize and monitor different swimming styles. It can also be used to control the music playback functions of the mobile phone. The advantage is the ability to lock the display, we also mentioned various dials and adjustable brightness. You will not find these conveniences in the older Mi Band 3.
And speaking of water, fortunately there has been no change here, so both models being compared are waterproof and should last the dive until to a depth of 50 meters below the surface.
The battery capacity has also increased
The larger the display with a clearer display, the more sensors naturally require more power. The battery capacity has increased compared to the older version from the original 110 mAh to 135 mAh. The manufacturer guarantees Mi Band 4 20 days per charge. The older model of the bracelet is similar.
The price may decide, but for both it is very low

A few words in conclusion
Both bracelets definitely have something to offer and the older Mi Band 3 is definitely not to be thrown away. However, the price difference between the two versions is at the level of a small sitting with a partner in a cafe. Therefore, we recommend paying extra for those few euros or crowns and getting a smarter novelty. At least the display is worth it.
