As for the today view, there arent many big changes. The one addition that I did notice is a new battery widget, which shows the battery life of devices connected via Bluetooth. This was obviously added with the Apple Watch in mind, but it also applies to other devices like Bluetooth keyboards, speakers, and headsets. Its important to keep in mind that your Bluetooth device has to report its battery life to the host device in order for this to work. Youll know if it does if youve ever seen a small battery symbol next to the Bluetooth logo in the status bar when your device was connected. For example, I have a Plantronics and a Creative headset here that do show up in the battery widget, but a pair of Sony headphones and an older Creative set that do not.
