In China today Xiaomi has unveiled Mi Band 4. It sports a brand-new colour AMOLED panel, and still has incredible 20-day battery life. A six-axis accelerometer supports a range of activity monitoring, and the new Mi Band is now more customisable than ever with a range of bands and complications (watch faces) available for it.
As anticipated there are both standard and NFC-equipped (for mobile payments variants), which will retail in China at 169– and 229 CNY – the same price as Mi Band 3 for the entry model, which retails at £26.99 in the UK. Mi Band 4 is roughly £19 and £26 when converted to Sterling, so we would not expect Xiaomi to raise the price any higher than £30 when Mi Band 4 eventually gets its global launch.
An Avengers Series limited edition Mi Band 4 is also available at CNY 349 (£39), with three customisable bands and Marvel watch faces.
When is the Mi Band 4 UK release date?
Mi Band 4 goes on sale in China on 16 June, but Xiaomi has not confirmed when Mi Band 4 will get its global release. The UK on sale usually trails that of China by a few months, so it’s possible Mi Band 4 could make it to Europe in time for September’s IFA 2019 trade show.
If you can’t wait that long to get your hands on Mi Band 4 you will be able to import one from China, but be wary of a Chinese-language interface. In the meantime, Mi Band 3 is still an unbeatable deal in the UK, currently available at Amazon for just £21.73.

What is new in Mi Band 4?
A waterproof fitness band with incredible battery life, an integrated heart-rate sensor and sleep tracking, it was difficult to imagine how Huami might improve on Mi Band 3 which is sold within Xiaomi’s huge ecosystem of third-party products.
The original Mi Band went on sale in summer 2014, a basic sleep- and fitness tracker with standout battery life and a cheap price. In each new generation since it has improved, with Mi Band 1S adding a heart-rate sensor, Mi Band 2 adding an OLED screen with basic notifications, and Mi Band 3 increasing the size of that display and adding the ability to read messages onscreen. The 2018 update also improved waterproofing, allowed the tracking of specific activities, and swapped in a higher-capacity battery.
Mi Band 4, announced in June 2019, boasts a larger 0.95in display (previously 0.78in), and Huami has swapped out the previous 80×128-pixel OLED display for a colour AMOLED panel with 120×240 pixels, along with 2.5D glass on top and a choice of 77 watch faces. It retains its touch-based interface, but Mi Band 4 additionally has a built-in mic for voice commands, which can be used to control connected devices.
This panel is still used for monitoring activity stats and weather reports, receiving smartphone notifications, finding your phone and controlling music playback, but can now additionally be used to make mobile payments if you opt for the NFC-equipped model.
Taking advantage of the device’s 5ATM waterproofing, Xiaomi’s latest Mi Band is now capable of swim tracking – something you don’t find in many fitness trackers several times the price. Using its six-axis accelerometer it is able to distinguish between strokes, and offers a SWOLF (Swim Golf) score to analyse performance. Other physical activities monitored by the new Mi Band include cycling, running and walking.
