iPhone 4S iOS 9.2.1 vs iOS 7.1.2 Speed Test



So we have learned that iOS 9.2.1 is fast, and is faster than iOS 8.4.1 on the 4S.. But what about if we go one more release back, and compare it against iOS 7.1.2 also on the iPhone 4S.
Let’s see how 7.1.2 compares against the latest and greatest iOS 9.2.1 Build 13D15.

See iOS 9.2.1 vs 9.2 videos for release notes.

  6. Can someone help I go to setting on my iPhone 4s and It Says My Phone Is Up to date but it's not Can someone Help

  7. ios 9.3 on the phone

  8. iPhone 4 is the best of all iPhones #facts thanks apple for the update software 😜

  9. I have a iPhone 4s on iOS 5.11 and iPhone 5 on 6.0 and 5s on 7.0.4 and 4 on 5.11

  10. App store open in ip4s on ios 7.1.2 as fast as ip 6s ios 9

  11. May the iPhone 4s live on!

  12. ios 7.1.2 is old but is faster

  13. My 4s is 7.1.2 and its slower than both of yours, why is that? Anything I can check? It is jailbroken and I do have quite a few perks installed.

  14. If I factory reset my iphone 4s, it would get to ios 6 right? Will I be able to restore the phone and keep ios6? And if I decide to update I will be able to update to ios 9 only, correct?

  15. My wife's jailbroken iPhone 4s on IOS 7.1.2 is faster in some cases than my iPhone 6 on iOS 9.2!

  16. Glad i found this. Definitely not upgrading.

  17. ios 9 is for 2gb ram and ios 8 and lower is for 1gb ram

  18. It would not be suprize if – iphone 4s
    ~add app deley
    Just to get slower running device and make them upgrade xD

  19. I've learned from bitter experience (with 2 iPhones) that ANY iOS 'upgrade' is simply a mechanism for making your device obsolete, and forcing you to upgrade. It's always been Apple's strategy and will never change.

  20. I would like to see 4s on 7.1.2 vs 6s on 9.2.1. New iOS is slow in every move, wtf.

  21. Everybody is saying that iOS 9.2.1 is slower, but I see the future brightly. Couple of patches and it will run the same or even better than iOS 7. I hate the new design, so on my iPad 2 I downgraded to 6.1.3, but this is is obsolete. iOS 7 will be obsolete in the near future, so if iOS 9.3 will have performance improvements like iOS 9.2 had it will run like iOS 7.1.2.

  22. Is there any way to downgrade to ios 7.1.2?

  23. How do you keep your battery on 100% for more than even 2 minutes? Me, having an Iphone 4s with iOS 9.2.1 have problems when it comes to battery life. My battery dies in 1 to 1 1/2 hours. I have tried everything, Airplane mode, low battery mode, background app refresh etc, every single way to limit battery usage. Any advice?

  24. How do you keep your battery on 100% for more than even 2 minutes? Me, having an Iphone 4s with iOS 9.2.1 have problems when it comes to battery life. My battery dies in 1 to 1 1/2 hours. I have tried everything, Airplane mode, low battery mode, background app refresh etc, every single way to limit battery usage. Any advice?

  25. I have a phone already but should I get the 4s for backup?

  26. Every update makes the old iPhone slower so you will want to get the new one, there are no bug fixes!

  27. I'm still on iOS 7.1.2 (iPhone 4s) That's a good feeling 🙂

  28. How about ios 6.1.3 vs ios 9.2.1 on iPhone 4S? I'm still on ios 6.1.3 iphone 4s and would love to see a comparison!

  29. does the iPhone 4s run on LTE?

  30. @iAppleBytes is time to upgrade my 4S to last iOS 9 version?

  31. IOS 9.2.1 is NOT faster than IOS 8.4.1. It is way slower in every scenario. It is made like that so users would change their phone or tablet with a new one. IOS 7 is way faster on my iPhone 4 than IOS 9 or 8 on my iPad 2 witch has a dual core CPU, my iPhone 4 has a single core cpu. This is the real truth.

  32. Too sad to watch this video, last video iOS 841vs921 gave me some exciting news, but this video is a strike! Is iOS ever going back to its "fast nature" as in iOS 7 and previous? New devices are still not so promising!

  33. Maps lags horribly on ios 9.21 zooming in and out however on ios 7.1.2 it is smooth

  34. And ur apps test that was just shitty wifi

  35. This is bull my iPhone 5s starts faster than both and it's running iOS 9.2.1
