It turns out, gyroscope, compass and accelerometer on some flagship smartphones were not properly calibrated and therefore reported incorrect data.
First, check the operation of sensors volunteered editing Gizmodo, which data with the two iPhone 5s and ordinary Fives running the latest version of iOS, with the present level and compass, confirming the existence of the problem. A little convinced of this and other sites.

Employees share a few times to calibrate compass in the application and get the same result – the first two smartphones are confident that they are on a level surface, but 5s thinks otherwise:
The level of error in each phone is different: some have reported a deviation of 2 °, the other was a bit more – about 4-6 °, others did not encounter such errors, and the fourth carried the defective smartphones to the nearest Apple Store and got a change of a normally calibrated sensors. All these facts suggest that the problem lies in the “hardware” and not in the software.
Either way, be sure to check iPhone 5s before purchase, if you are planning to buy a smartphone in the near future.
