Huawei sub-brand Honor has unveiled the Honor 4 Band. The successor to the Band 3 comes with 0.95-inch AMOLED display with a touchscreen that is protected by a 2.5D curved screen and is accompanied by a Home button. The Honor Band 4 will start retailing for an asking price of approx. $30.
 
The Band 4 from Honor will come with Huawei TruSeen 2.0 continuous heart-rate monitoring, meaning the device will monitor your heart rate all the time. The Honor Band will display the measurements on its fitness app and will also prompt you if your heart rate is too high.
 
Huawei claims that the smart band comes with the company’s TruSleep 2.0 technology which employs cardiopulmonary coupled dynamics spectrum (CPC) to monitor a user’s sleeping patterns including REM mode. The band also offers NFC support and thus enables contactless payments. As part of the regular fitness tracking, the device can track the calories burnt, distance covered, steps and swimming speed and will also notify you about your incoming calls and texts.
 
The device will be able to connect to smartphones through its Bluetooth v4.2 connectivity and is compatible with iPhones running iOS 9.0 or higher or Android devices with Android 4.4 or later. The Honor Band 4 is dust and water resistance to up to 50 metres and can last for as much as 14 days on a single charge when continuous heart tracking is turned off and 6 days when the same is turned on.
