Speed comparison between iPhone 4S iOS 7.1.2 and 8.0.2
This test was made on 2 virgin iPhone 4S. The conclusion has to be that 7.1.2 is slightly faster. It was mostly visible on the Appstore app. Other Apps are only milliseconds slower, same applies to Apps not shown in this test. I have to stress that the test has been made on freshly restored phones, that are not weighed down by tons of text messages, full camera roll etc. September 27th 2014
