News Xiaomi Mi Band 4: New Fitness Tracker with Bluetooth 5 – first pictures

New info about the hotly awaited Mi Band 4, the new fitness tracker from Xiaomi. Apparently it’s coming sooner than expected. Even if we don’t get any “Specs” delivered, you can take a first look at the Fitness Tracker. The leaked pictures of the NCC show the alleged Mi Band 4, which reminds of a combination of Mi Band 2 and Mi Band 3.

The touchscreen should be a bit as big as its predecessor, where the diagonal is 0.96 inches. However, the glass doesn’t seem to be quite as round as on the Xiaomi Mi Band 3. On the underside you can see a heart rate monitor again. However, here we see only the actual tracker and not the strap that is attached to it.

The charging process has changed because the charging contacts are now on the underside, no longer on the side. You put the tracker on a small station for charging and don’t put it into the “charging cover”. This makes it clear that the last generation charging cable is not compatible.

The Xiaomi Mi Band 2 was a milestone for Xiaomi. It convinced with a lot of power for a small price and could pave the way for the also very successful Xiaomi Mi Band 3. Now the successor awaits us soon: the Xiaomi Mi Band 4 is already in the starting blocks!

First information

Not much is known about the new fitness tracker from Xiaomi or Huami yet. Recently the Huami CFO confirmed that the Xiaomi Mi Band 4 will be released in 2019. This would shorten the gap between the generations of Mi bands considerably, but it fits perfectly into the new release rhythm of the manufacturer, which we also know from smartphones. The company’s current Fitness Tracker came onto the market in summer 2018, and a similar time could now be conceivable. After all, the now published Bluetooth certificate gives an indication of the current status of production.

Xiaomi Mi Band 4 Bluetooth Certificate

What will change purely technically is the Bluetooth standard. While the Xiaomi Mi Band 3 still uses Bluetooth 4.2, the Xiaomi Mi Band 4 uses the current Bluetooth 5 standard. This is now confirmed by an official certificate, which confirms this technical innovation. The higher range, the fast data transfer rate and the lower energy consumption speak for the new Bluetooth standard. So we can hope that the Mi Band 4 can shine again with a good battery life.

Xiaomi Mi Band 4 Bluetooth Certificate NFC

Furthermore, we can see from this certification that there will again be two versions of the band. One Mi Band 4 and one Mi Band 4 with NFC. The predecessor also came in a separate NFC version, which is not suitable for the European market due to lack of compatibility with Google Pay or other services. We can only hope that this will change in this generation.


Otherwise it is to be expected that Huami Amazfit, the manufacturer of the band, will stick to the touchscreen design, but hopefully be able to optimize it a bit. Otherwise the range of functions should be similar, especially to leave room for the more expensive Amazfit models, e.g. Huami Amazfit Stratos 2. After all, the Mi bands are aimed at the budget range among wearables.

What new functions and features would you like to see in the Xiaomi Mi Band 4?
