Since then experts test many mobile devices, exploring the ability of gadgets to receive mobile waves. Energy Agency and the Commission, which includes Denmark, Finland, Norway and Sweden, tested the 26 most popular in the smartphone market to find out which ones provide the best voice quality and most stable reception of the signal from the base station. In this experiment, the Apple could not boast of record results.

Each device was tested in two ways: in the first case the device was put on the table, the second held in his hand.

The Apple smartphones for voice quality and reception took not the first place. In particular, when testing on the table iPhone 6s, iPhone 6s Plus and iPhone 6 were on 12, 13 and 14 respectively. In the second case, the result is even worse: the iPhone 6 and iPhone 6 Plus won 21 and 22 seats, and the iPhone 6s and iPhone SE 25 and 26, respectively.
