He took the iPhone X R and iPhone 6 Plus, walked 6 meters away from the Wi-Fi access point and ran a speed test. The results frankly surprised.
iPhone X R is three times slower when downloading data and twice as long as it is sent.
Other users are interested in the test. This is how the results of Wi-Fi speed in Xs Max vs 8 Plus appeared:

In all tests, the flagship failed testing for younger models.
