Xiaomi’s Mi Band has become the industry standard as far as value for money fitness bands are concerned. The Mi Band 4, that has just launched in China (and should arrive in India soon), takes things to an all new level by adding a curved colour display, NFC, a six-axis accelerometer and built-in microphone so the band can also respond to voice commands.
All this, and the Mi Band 4 continues to be surprisingly affordable – pricing starts at CNY 169 (roughly Rs 1,700) for the standard edition, while the NFC edition will cost buyers CNY 229 (roughly Rs 2,300). There’s also a limited-edition Mi Band 4 that Xiaomi is bringing in partnership with Marvel Avengers for CNY 349 (roughly Rs 3,500).
The main highlight of the Mi Band 4 is its colour OLED display that’s nearly 40 per cent bigger than the outgoing Mi Band 3 – more precisely, the Mi Band 4 comes with a 0.95-inch AMOLED colour display with a 120x240 pixel resolution and 2.5D scratch-resistant glass up-top. The colour AMOLED display allows Xiaomi to bring custom watch faces to the Mi Band 4 – there are as many as 77 colourful dial themes on offer here. Adding some more colour to the Mi Band 4 is a choice of eight distinct bands.
The Mi Band 4 retains the continuous heart rate monitor and sleep quality index features of the Mi Band 3, and adds a new six-axis accelerometer into the mix for enhanced tracking including swimming stroke recognition - the Mi Band 4 is 5ATM-certified which means that it is swim-proof.
There’s also a built-in microphone now so users will be able to access voice commands and also control IoT devices with the Mi Band 4. There’s also NFC on-board now for enabling digital payments and generally faster connectivity – NFC is limited to the top-end model only though.
Speaking of battery life, the Mi Band 4 standard edition boasts of a 20-day battery life while the NFC variant is claimed to offer 15-day battery life on single charge.
