Huawei Band 4 Smartband 2.5D Display with Optical Heart Rate Sensor - Black

Product Description

The Huawei Band 4 features a 0.96-inch TFT display with 80x160 pixels resolution and 2.5D curved glass protection. Under the hood, the fitness band has an Apollo 3 SoC and carries a series of sensors that include a three-axis accelerometer, infrared sensor, and an optical heart rate sensor. These sensors power features such as Huawei TruSeen 3.5 to monitor heart rate and Huawei TruSleep 2.0 to recognise the four phases of your heart rate during the sleep and analyse the sleep quality. Huawei has also offered the tracking of various fitness activities, including outdoor and indoor run, walk, cycle, elliptical, and free training. Further, the band provides notifications of new messages and phone calls directly from the connected smartphone and delivers features such as Find My Phone and Remote Shutter. Unlike many other smart fitness bands and wearables, the Huawei Band 4 comes with the built-in USB plug that lets you charge the device without requiring a specific cable or charger. The company also claims that the 91mAh battery of the Band 4 delivers up to nine days of power on a single charge.
