Apple’s iOS 5 Caught Speeding [Infographic]

SMS Text

New Relic, a company that measures and manages the performance of Web applications, recently released the results of a study that examined the performance differences between mobile Safari on iOS 4 and iOS 5 on same model iPhones. The study concluded that the Safari browser loads pages three times faster on iPhones with iOS 5 than the Safari browser on iPhones with iOS 4.

New Relic came to their conclusions using two testing methods. The first test was uncontrolled and examined the average Web application response times that 3,000 randomly-sampled New Relic customers experienced. The New Relic team tracked the users’ browser performance when loading over 3,000 apps. The results of this test indicated that the average page load time was 4.1 seconds with iOS 5 and 9.6 seconds with iOS 4. Of note, this field test did not have the capability to gather data such as which carrier users were on or whether people were using 3G or Wi-Fi.

The second test was conducted in a controlled laboratory setting. One iPhone with iOS 5 was tested against another iPhone with iOS 4; each phone had identical hardware. In this lab test, Web pages loaded in an average time of 1.88 seconds on the iOS 5 phone and 6.34 seconds on the one with iOS 4.

The new iOS 5 was released on October 12. In addition to offering a faster Safari browser speed than iOS 4, the new operating system’s features include over 200 new features including iMessage, Notification Center, NewsStand, Twitter integration, and an improved Camera app. IPhone users can connect their device to iTunes in order to download the new operating system.

  • I don’t think this study proves anything about iOS 5 being faster than iOS 4 if you didn’t check to see if someone was using wifi. When I’m on wifi on my phone I get immediate responses – regardless of when I was on 4 or 5, but when I’m not connected to wifi, my load time varies depending on signal strength. Nice try, but there are too many variables not being controlled.

      Although the first test was in an uncontrolled setting (the article mentions that), 3000 users is a fairly large and statistically relevant sample size. However, even if you do not agree that the findings from the first portion were statistically relevant, what about the second test (similar results) that was tested in a controlled lab setting? In my opinion, the controlled lab test validated the findings of the uncontrolled test or at a minimum proved there is something to the hypothesis.

  • This is good news because the iOS 5 will run on my 3Gs!

    In spite of all the new features of the 4 models, I stayed away from them because they are like a square mini brick in your hands with sharp edges.

    I’m surprised no one ever talks abou how bad the sharp edges felt in their hand after the perfect feel of the 3 series.

    I will consider the 5 series when it comes out.
