5 reasons to buy the Mi Band 4 over the Mi Band 3

“Possibly the biggest reason to buy the Mi Band 4 over the Mi Band 3 would be the colour AMOLED display”

The Mi Band 4, priced in India at Rs 2,299, is the latest fitness band in Xiaomi India’s ecosystem lineup, which has grown exponentially over the past few years. Successor to last year’s Mi Band 3, the Mi Band 4 joins a long list of affordable fitness trackers from brands like Samsung, Honor, and Lenovo in the market. However, it has to live up to massive expectations, considering the Mi Band 3 was the largest selling wearable device in India. Here are 5 reasons you should buy the Mi Band 4 over the Mi Band 3.


Possibly the biggest reason to buy the Mi Band 4 over the Mi Band 3 would be the display. The successor is the first in Xiaomi’s wearable category to sport a full-colour OLED display, which is about 25 percent larger and significantly brighter than that of the Mi Band 3.

Talking about absolute numbers, the Mi Band 4 sports a 0.95-inch AMOLED panel with a resolution of 120×240 pixels compared to the 0.78-inch AMOLED display on with Mi Band 3 with 80×128 pixels resolution.

Battery life

Both the Mi Band 3 and the Mi Band 4 claim up to 20 days of battery life on a single full charge. However, in terms of specifications, the battery capacity on the Mi Smart Band 4 is significantly larger at 135mAh, compared to 110mAh on the Mi Band 3. This technically translates into battery life, as observed in our Mi Band 4 review.

Bluetooth 5.0

A big upgrade over Bluetooth 4.2 on the Mi Band 3, the Mi Band 4 gets the latest Bluetooth 5.0. While the Dual Audio feature cannot be used with the fitness tracker, Bluetooth 5.0 offers improved speed and a greater range over its predecessor. 

Swim tracking

Another highlight of the Mi Band 4 is swim tracking capabilities with stroke recognition. Especially helpful for frequent swimmers, this feature can track and distinguish between backstroke, butterfly, and 3 more swimming styles. It can also record different data sets for swimming.

Capacitive wear monitoring sensor

Another interesting addition to the Mi Band 4 is a capacitive wear monitoring sensor. This helps in two ways: first, it can detect whether you are wearing the band or not and decide to display notifications or not to safeguard privacy. Second, it can detect skin to disable sleep and heart rate tracking when not needed. This helps optimise battery life on the fitness band. 

If you find these reasons compelling, the Mi Band 4 goes on sale next at 1pm on September 28 across Mi.com, Amazon.in, and Mi Home stores.
