Nokia will roll out an update that will outfit all Lumia phones running Windows Phone 8 with the latest low-energy version of Bluetooth.
In a new FAQ, Nokia noted that the recent Amber update added Bluetooth LE to the Lumia 520, 620, 625, and 720. A future update dubbed Lumia Black will do the same for all other Windows Phone 8 Lumia handsets.
What's so special about Bluetooth LE? Built into Bluetooth 4.0, the low-energy technology lets you pair your phone with special accessories designed for health and fitness, among other areas. With Bluetooth LE, the accessory's battery charge also lasts considerable longer than it would using an older version of Bluetooth.
