I can see the reviews here partly not understand.

The longer you use the IPhone better is that.

If the display is initially too big, you think after two weeks already, how could ever cope with the little 5 Series.
All this criticism of the speed of the processor and something I find absolute nonsense. But nothing really anything on the device is slow.
The display is sharp (it may but devices with higher resolution provide what the hell?).
The handling is good as always, everything is there where it is suspected.
The fingerprint sensor is working perfectly.
Battery performance is sensational, partly needs of normal use, (read emails, even playing what, listen to music) the IPhone 3 days not connected to the grid.
After the update, the Bluetooth connection is working in the car again perfectly.

After a month of use, I can now only positive things.
