As you all know, the latest final version of iOS is iOS 9.1 and at this time the developer and public versions of iOS 9.2 have already been released. The new version, in addition to including bug fixes and stability and fluidity improvements, will come with the main novelty of improvements in the Safari driver, which will allow third-party applications to run in them a browser that will take advantage of some Safari functions , such as the ability to use content blockers or the reader. Although there are many users who affirm that iOS 9.2 is much better than iOS 9.1, it is best to put both versions face to face to compare their speed and then you have three videos which compare the operation of iOS 9.1 with that of iOS 9.2 beta 2 on an iPhone 4S, on an iPhone 5 and an iPhone 5s.
As you can see in the videos, the speed difference between iOS 9.1 and iOS 9.2 beta 2 is minimal. We can even see that iOS 9.1 is faster when opening some applications than iOS 9.2 beta 2, but we could say that there is a tie because there are cases in which it is just the opposite.
Although it is true that it would have been interesting to also see a comparison on an iPhone 6s, which is the device for which the latest version of iOS is most optimized, but in this triple comparison, the "less new" devices have been used, which are also the ones that will have the most performance issues. Also keep in mind that iOS 9.2 is still in its second beta, so they will still release three or four versions before the final version is reached, and that may be a drag on the newer version of the two. According to the comments of those who have tried it, iOS 9.2 fixes many of the lag problems that have appeared in iOS 9.
In the 5S they still do not fix the lag… .Then you see the Iphone 5 and you see that it does not have any lag. I do not understand anything
What lag ???
You're right. iOS 9.1 on iPhone 5 is great and does not lag like in the 5S, it is incredible. I certify it because my wife has an iPhone 5 and hers feels smoother, and that she updated from 8.4 direct. Instead I deleted everything and installed it from 0 with iTunes to see if the lags disappeared, and on the contrary, you can see more: /
The lag in Spotlight continues to exist… At least on an iPad 3. And the animations are all still crude…. I still don't understand why it is impossible to do the same but more fluidly.
Although they are a reference, these analyzes only give an idea of what can happen. Each device behaves based on its configuration and installed software (it is not the same to have or not have many programs with localization activated or to have many with updates in the background), hence there are users who suffer delays and others do not on more devices. ancient. My iPad 2 goes better with 9 than with 8 clearly and if certain not very essential settings are properly set even better.
Hello everyone. I think it does not depend on the model itself (mostly) but on the figurative things that each one has. Otherwise it is not understood why some with older devices do well compared to others with newer devices. And yet among the same teams, some are doing well and others are not. Personally, I have a 5s and I'm doing excellent; but others with 5s also fare badly. It sounds more like configuration issues to me (although it should not vary by configuration) than anything else.
