Xiaomi presented Mi Band 4 - the next iteration of its fitness band, which previous generations - probably due to the low price - were sold in amazing quantities, making Xiaomi the leader of this market segment.
Xiaomi Mi Band 4 - like the previous generations, is waterproof. Durable immersion up to 50 meters deep - 5 ATM. The new model has a larger - and most importantly colour - AMOLED screen with a diagonal of 0.95 inches, brightness of 400 nit and a resolution of 120 x 240 pixels. Thanks to the new screen, it will be possible to personalize the band in the range of interface colours.
The band measures the heart rate, monitors the sleep and registers the user's activity, of course. The device is equipped with a three-axis gyroscope, accelerometer and microphone, which in China is used to control with the voice assistant Xiao AI. It is not known what role it will take globally - but we can’t rule out the Google Assistant. The case with the NFC module looks similar - it is not known to what extent it will be used in the global variant of the band.
Power is provided by a 135 mAh battery, designed to provide up to 15 days of work. You can choose from several colours of the band, including the limited edition of the Avengers. The device costs 169 or 229 yuan (with NFC), or 25-33 USD.
