Is iOS 9 Slow, Lagging, & Stuttering on Your iPhone / iPad?


iOS 9 is buggy. Or at least that’s what we see. In fact, we have reports of users facing several issues with the new iOS 9.0 firmware, and out of all those minor and major issues, three of them stands out: iOS is slow, lags and the basic animations stutters on iPhones and iPads.

This is a common problem.


Along with this, there are unexpected app crashes that takes you back to the homescreen. In this article, we explore this further.

iOS 9 Is Really Slow & Lags

Older devices like iPhone 5s, 5c, 5, 4s seem to have taken a beating after upgrading to iOS 9.

Even new models like iPhone 6 and 6 Plus are slow on certain occasions (discussed below).

For example, when you use the keyboard, it takes some time to come up on your screen. Plus, tap on it and you may notice a delay / lag.

Control Center lags when you swipe from the bottom to open it.

Even swiping through pages is a slow affair. Personally, these issues were already visible on iOS 9 beta – although we thought the stable iOS 9 version would have fixed it all.

iOS 9 Has The Worst Stuttering Problem

As iOS 9 gets a new multitasking interface, it stutters heavily when you have lots of apps left open on your iOS devices.

Users have reported that such stuttering animations are visible when you swipe through the pages from homescreen, open Spotlight, or scroll inside apps. Even the improved Safari browser lags when you scroll through websites.

Case in point: We have a video showing the scrolling issue in iOS 9 that appears when you use the App Store:

We went deeper to find more. In fact, we confirmed with several users and asked what they think of all these problems. And the answers weren’t surprising at all.

Then, we checked Twitter. Here are some of the users expressing their frustration with iOS 9:

What’s the fix? Well, we are waiting for the new iOS 9.1 or any minor update from Apple that promises to improve the performance… and hopefully put an end to all the minor and major problems you see now.

So the only solution is to wait.

Of course, temporarily fixes include:

Performing a hard reset.

Do a fresh, clean install of iOS 9.

Or downgrade from iOS 9 to iOS 8 – although that’s a time-consuming process.

Over to you:

Let us know the kind of issues you are facing with iOS 9 through the comment section below.

Apple promised that iOS 9 performance will be far better than everything else we have seen, but the video and users tell a different story. We admit the issue isn’t “widespread” – and only some percentage of users were affected with such lagging issues.

Still, it’s unacceptable. And Apple, if you are reading this? Please bring us a new iOS 9 update as soon as possible!

One that is lag-free, crash-free, and stutter-free.

  • I can confirm I’m experiencing this issue too. 5s.

    It seems Apple has decided that their customer base should do the quality conforming on their upgrades from now on. ios 9 and 9.0.1 is the Worse upgrade in the 6 years that I have been an avid Apple product user.Apple is doing a good job of copying Microsoft as they (Microsoft) were the first to use their customers as guinea pigs and quality controllers. Shame on you Apple. Steve Jobs will turn in his grave because of this crap. Get your act together and don’t put updates out there unless they are 100% bug free.

    Late to the discussion here, but I’m surprised indeed by IOS 9’s lagginess. Sometimes a second attempt has to be made to even get a screen to scroll, no response the first time. Touch-and-hold on a word, and get a different response each time. Sometimes nothing, sometimes a menu, sometimes wild zooming in and out. This isn’t the Apple experience I’m used to. Up until IOS 9, my iPad air was almost “organic” in its response and smoothness. Now, I feel like I’m fighting with it.

    iPad Air is laggy and Safari is a nightmare to use now.
