Xiaomi is out with the Mi Band 4 — the successor to its massively popular Mi Band 3 from last year. The Mi Band 4 builds on its predecessor in very meaningful ways including the switch to a larger and colorful 0.95-inch OLED display that’s protected by a 2.5D glass.
The color display helps in giving the Mi Band 4 a more modern look and feel and also makes interacting with it easier.

Xiaomi has also improved the motion tracking capabilities of the wearable by using a six-axis high precision accelerometer. This allows for better motion and sports tracking and the Mi Band 4 can now even track your swimming strokes. The wearable continues to have a 5ATM rating meaning you can wear it while swimming without any issues.

The wearable now also comes with a microphone which is used to interact with the new built-in Xiao Assistant. Xiaomi is also launching another version of the Mi Band 4 with NFC that will be compatible with Alipay and public transport cards in China.

Other features of the Mi Band 4 include a heart rate scanner, Bluetooth 5.0, and up to 20 days of battery life. The NFC version of the Mi Band 4 offers up to 15 days of battery life. Despite packing so many features and improvements, the Mi Band 4 continues to carry an extremely affordable price tag. The non-NFC version is priced at RMB 169, with the NFC version carrying a price tag of RMB 229. There is also going to be a limited Avengers Edition release that will come in a special packaging with multiple bands for RMB 349.
