New features added to Microsoft Band 2 via update include music controls and activity reminder
The update also adds activity reminders. It is up to the user to decide how often he/she will get that kick in the butt from their wearable. And the feature can be set to 'stand down' while sleeping or driving. And once the Microsoft Band 2 user is up and active, it can track the duration of an exercise session, the user's heart rate, and the number of calories burned during specific activities.
The update is being sent out by Microsoft. When it arrives, you will find a "What's New" tile appearing on the Band. Tap it to see the new features offered through the update.
The Microsoft Band 2 is available from physical Microsoft Stores, and the online Microsoft Store. It is priced at $249.99 and features an AMOLED screen with a 300 x 128 resolution. The battery on the wearable will last up to 48 hours. The device will pair with Android (4.4 or higher), Windows Phone (8.1 or higher) and iOS (Apple iPhone 4s and later, and iOS 8.1.2 and later) via Bluetooth 4.0 LE.
