How Ios 9 Works On Iphone 4s
The letter “s” in the iPhone designation traditionally means “speed”, i.e. "speed". For iPhone 4s, this does not apply for a long time – iOS 8 on the oldest supported iPhone worked, frankly, not brilliantly. Should I upgrade 4s to iOS 9? In the "nine" there are several functions at once, which the iPhone 4s will not be able to support with all its desire.
These functions are not many, but almost every one of them is a pretty valuable thing.
What is not in the iPhone 4s
- New Spotlight Predictive Screen
- Touch id
- Handoff for applications (call forwarding from iPhone to Mac and iPad works without problems)
- Support for OpenGL ES 3.0, Metal API, 64-bit ARMv8 applications
Also by itself iPhone 4s – a very slow smartphone. It runs on the A5 chip, which is several times inferior to the new A9 in performance. Even released in 2012, the iPhone 5 is twice as fast.
Another big problem is the tiny 3.5-inch display. Difficulties appeared even in iOS 8 – a lot of space was eaten out by dictionary hints for typing on the keyboard, and Spotlight displayed no more than one search result. In iOS 9, the size of the buttons increased, they became more rounded. On the screen of the iPhone 5 / 5s or 6/6 Plus, you notice it and just shrug your shoulders – more and more, what’s the difference. But the 4s display will have to be scrolled – and yet in the "eight" everything was somehow placed on one screen.
Unfortunately, the performance as a whole remained at the iOS 8 level, or it became slightly worse – but not enough to notice the regression with the naked eye. The table below shows how fast iPhone 4s running iOS 8.4.1 and iOS 9.0:
As you can see, the only plus from switching to the Nine is a slightly faster launch of the Camera. On the other hand, the delays in updating from iOS 7 to iOS 8 were much more serious.
The thrill of working with iPhone 4s running iOS 9 – about the same as on the "eight". Little delays when launching applications have not gone away. On the same iPhone 5, everything works much more lively.
Should I upgrade 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 speed, and there are more than enough interesting features in iOS 9 – which alone costs an updated keyboard.
Perhaps the main advice is not to update, but to restore. Why and how to do this, we told in detail here. In this case, you will receive the fastest iPhone 4s. You will find some useful tips on speeding up iPhone 4s in this article.
Do you still prefer iOS 7? In this case, an update can also be done. You will lose in speed, but get access to the best programs from the App Store – hardly one serious developer will do anything for the “seven” that was released in 2013. Plus, iOS 9 is arguably the most stable build of iOS in the last few years – so after the upgrade, your nerves will definitely say thank you.
In addition, we’ll be honest – nothing is better than iOS 9, for iPhone 4s will be gone. Next year, Apple is likely to announce the completion of technical support for the best smartphone of the era of Steve Jobs.
