The new iPhone 6 comes with 802.11ac WiFi, and last years iPhone 5S comes with 802.11n WiFi, and now we have an iPhone 6 vs iPhone 5S video comparing the WiFi on the two devices.
The video below shows the difference in WiFi speeds on the iPhone 6 vs iPhone 5S, the video was put togther by the guys from iClarified, and both handsets were connected to an AirPort Extreme, more details below.
Both devices were freshly restored to iOS 8.0 and connected to the 2013 Apple AirPort Extreme. The router was placed 1.5 metres away from the smartphones and each iPhone was connected to the AirPort Extreme using a 5GHz-only network. No other devices were connected to the wireless network at the time of the test and the downloads were performed at separate times. We cut them together for comparison.
As you can see from the video, there is a notable difference between the two devices, the iPhone 5s had a top speed for 101.1 Mbps and the new iPhone 6 had a top speed of 278.5 Mbps, which is almost three times faster than last years iPhone 5S.
The iPhone 5S has been replaced by the iPhone SE, have a look at our comparison of the iPhone 5S vs iPhone SE.
