This has not been the case for a long time - iOS 8 on the oldest supported iPhone worked, frankly, not brilliantly. Is it worth upgrading 4s to ? The “nine” has several functions that the iPhone 4s will not be able to support even if it wanted to.

There are not many of these functions, but almost every one of them is quite valuable.

What the iPhone 4s doesn't have

  • New Spotlight screen, predictive input
  • AirDrop
  • Touch ID
  • Handoff for apps (call forwarding from iPhone to Mac and iPad works without problems)
  • Supports OpenGL ES 3.0, Metal API, 64-bit ARMv8 applications

Moreover, on its own iPhone 4s- a very slow smartphone. It runs on the A5 chip, which is several times inferior to the new A9 in performance. Even the one released in 2012 works twice as fast.

Another big problem is the tiny 3.5-inch display. Difficulties appeared in iOS 8 - dictionary hints for typing on the keyboard took up a lot of space, and only one search result was displayed. In iOS 9, the size of the buttons has increased and they have become more rounded. On iPhone screen 5/5s or 6/6 Plus you notice it and just shrug your shoulders - more and more, what's the difference. But on the 4s display you will already have to scroll - but in the “eight” everything somehow fit on one screen.

Unfortunately, performance overall remained at the level of iOS 8, or became slightly worse - but not enough to notice the regression with the naked eye. The table below shows how fast iPhone 4s under iOS control 8.4.1 and iOS 9.0:

As you can see, the only advantage of switching to “nine” is a slightly faster launch of the Camera. On the other hand, the delays when updating from iOS 7 to iOS 8 were much more serious.

Feelings of working with iPhone 4s running iOS 9 - approximately the same as on the G8. There are still small delays when launching applications. On the same iPhone 5, everything works much more vividly.

To be fair, Apple did work on performance iPhone 4s— in Javascript benchmarks its results have improved, but the running time has not decreased:

Is it worth upgrading to iOS 9?

If your iPhone 4s works on iOS 8 - definitely yes! The screen will be even less convenient than before, but nothing has changed in terms of speed, and interesting features More than enough has appeared in iOS 9 - which is worth the updated keyboard alone.

Probably the main advice is not to do an Update, but a Restoration. We explained in detail why and how to do this. In this case, you will get the fastest iPhone 4s. A little useful tips You will find information on speeding up iPhone 4s in the article.

Do you still prefer iOS 7? In this case, an update can also be done. You will lose speed, but gain access to the best programs from App Store- It’s unlikely that at least one serious developer will do anything for the “Seven” released in 2013. Plus, iOS 9 is arguably the most stable build of iOS in years, so your nerves will definitely thank you after the update.

Plus, let's be honest, there's nothing better than iOS 9 for iPhone 4s it won't be anymore. Apple will probably announce the end next year technical support best smartphone Steve Jobs era.
