Update, May 20, 2019 (1:11PM EST): We now have a new leaked images and several details of the rumored Mi Band 4, courtesy of GizmoChina.
Based on the images, the Mi Band 4 eschews the monochrome display of its predecessor for a color display. We also get a glimpse of the updated UI elements in the image, with the home screen showing the time and the number of steps you’ve taken so far.
There’s even a call screen shown in the image, which means you might be able to use the Mi Band 4 to make and receive calls.
As for supposedly confirmed details, the Mi Band 4 reportedly features Bluetooth 5.0. The device also comes with an improved “Heart Rate Monitoring” system and two models: XMSH08HM and XMSH07HM. The former model supposedly includes NFC, while the latter model doesn’t include NFC.
Finally, the NFC version reportedly costs 499 yuan (~$72). That’s compared to the standard version, which might cost between 200 and 300 yuan (~$28-$43).
Original article, May 14, 2019 (4:19PM EST): With Taiwan’s NCC certification agency already giving us a first look at the Xiaomi Mi Band 4, renders leaked today on Slashleaks give us a clearer look at the upcoming fitness tracker.
The renders seemingly confirm that the upcoming Mi Band is the first in its line to feature a color display. It also looks like the Mi Band 4 features Xiao AI, Xiaomi’s virtual assistant that debuted in April 2018. Similar to Google Assistant, Xiao AI checks the weather, controls smart appliances, performs translations, and more.
Lastly, the capacitive button on the Mi Band 3 is seemingly replaced by a capacitive button on the fourth iteration.
Based on a previous report, the Mi Band 4 features Bluetooth 5.0 connectivity and a heart rate sensor that is likely a photoplethysmography (PPG) monitor. There might also be a second variant that features NFC, though this version might only be available in China.
Unfortunately, there’s not much else we know about the Mi Band 4. Expect the upcoming fitness tracker to look very similar to the Mi Band 3, which you can buy at the link below for around $30 if you want an idea of what to expect. Otherwise, it’s worth waiting a few months to see if Xiaomi announces the Mi Band 4.
