I use to connect my Nokia Lumia 930 Bluetooth which so far works very well.
App notifications LED are only possible if the device is activated under Accessories Hub apps in the settings.
The notification LED will turn off only if all notifications are deleted from the Info Center,
pure call and view InfoCenter is not enough for it.
The purpose of the multi-function button opens up to me have not, since this is inconveniently on the bottom.
The Ladvorgang takes about half an hour longer than the AC adapter,
But what Klapptasche can be caused possibly by the leather used by me.
With me so take a charge of 10% to 95% about 2 hours.
The operation of the charging station on a USB 3.0 port on the PC is no problem
and the charging time will be not appreciably longer than if the charger is connected via the power supply unit.
All in all, quite an expensive but useful gadget, which also indicates new messages or low battery and protects the USB connector.
For the price Nokia would but calm may still spendieren a PSU with.
