Shortly after the release of iOS 8, tests shown by Ars Technica noted iPhone 4s users may experience a negative performance impact with the latest version of iOS on their ‘aging’ smartphone.

A new video released by YouTube user kabriolett (via 9to5Mac) today shows a speed test between newly released iOS 8.0.2 versus iOS 7.1.2 on the iPhone 4s, setup as a brand new phone.

Here’s what the uploader has to say:

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

As you can see from the test above, the performance impact is there, but not a huge one, aside from the App Store app loading slowly on iOS 8.0.2. Of course, these freshly restored phones aren’t bogged down by app installs, pictures and more, so a truly real-world test might show a bigger impact on performance.

Apple stopped signing iOS 7.1.2 yesterday, so that means if you upgraded to iOS 8, you cannot downgrade any longer.

Did you install iOS 8 on your iPhone 4s? How is it so far?

    Unfortunately there is more to testing the performance of ios 8 vs 7 than simply the opening of apps. Wh this person neglected to demonstrate

  • Yeah it could have been more thorough but it shows the stock performance out of the gate. It’s better than nothing since you can’t downgrade once you update to iOS 8.0.2 now.

  • Riddlemethis

    There really is no point to this comparison. Like already mentioned opening and closing apps and the speed is pretty much meaningless.

    Besides, most iPhone 4S users already complained about the lag and poor performance going to 7.1.2.

    How about a performance test including multitasking and graphics between 6.x to 7 to 7.1.2 to 8.02?

  • Riddlemethis

    I disagree. It’s really a useless piece of bias video published to promote iOS 8. Nothing more.

    I did so before I got my new 6. I was not noticing any problems and was quite happy to see it perform so well. The only problem app was FB, but then, it’s always slow as mall lasses in winter.

    I have found that, within hours of upgrading my 4S to iOS 8+, my phone gets “stuck” in landscape mode after turning the phone back to portrait mode. It seems random (or I haven’t divined the common circumstance) but I have to close an App or 2 or toggle the home button to get it to correct itself. I NEVER saw this problem prior to iOS 8.

  • I’m seeing this on the iPhone 6 Plus too. Looks like an iOS 8 bug.

  • Canuck_2009

    This is the first “other person” note that described this rotational issue that I have seen. Nice to know it isn’t just me!

  • It hasn’t happened a lot but when it does, it’s super annoying!

  • Canuck_2009

    Interesting that I haven’t seen the same issue on my iPads now running iOS 8+. I don’t think I will upgrade our 2 other iPhone 5 to iOS 8 ’till Apple gets some of this crap sorted out.

    Used to be that I looked forward to Apple OS upgrades ’cause they always brought new functionality and/or performance. Now I tend to say “Oh-oh … here we go again”. Similar kinds of issues with my upgrades to OS X Yosemite on my Mac mini and MacBook Air.

    The music on this video is terrible.

    This video is total bull, iOS 7 didn’t have the battery indicator in the camera app, nice try fool. What is ur purpose, “point”. Why are you faking a test that doesn’t show anything?

    You’re an idiot
