iOS users are installing Apple's latest operating system at roughly the same pace iOS 8 was installed last year, according to multiple analytics companies that are tracking iOS 9 adoption rates. iOS 9 has now been available for download for just over 24 hours.

Mixpanel's live iOS 9 tracking site suggests iOS 9 is now installed on approximately 12.60 percent of devices, which is in line with iOS 8 adoption rates in 2014.

"iOS 9 has received 12% adoption in the last 24 hours and is being adopted similar to iOS 8 last year. This kind of adoption took Android's latest operating system, Lollipop, in comparison 5 months to achieve. One huge advantage Apple got right this year over last year was that the update is much smaller than last year (3.5x smaller) < Apple has empathy for its users who have nearly maxed out the space on their phones. However, one issue for it being substantially slow compared to iOS 7 is that servers are having trouble keeping up right now as people update."
Because each analytics site tracks a different selection of iOS users based on app installs, iOS 9 installation numbers vary quite a bit across platforms. All of the sites tracking iOS 9 adoption agree that it is on pace with adoption numbers seen after iOS 8 was released last year, however. Tapjoy is seeing adoption rates spanning from 4 percent to 7 percent, based on device, while Fiksu is seeing 6 percent of its users running iOS 9.

According to GoSquared, iOS 9 users now represent 12 percent of total iOS traffic, a number that's on par with both Mixpanel's count and an 11.84 percent measurement from analytics company Paddle.

Two years ago, iOS 7 saw much quicker adoption rates than we're seeing with iOS 9, but that is not surprising as iOS 7 marked the last major design update to the operating system. iOS 8 and iOS 9 brought many new features, but few visual changes.

What is surprising is that iOS 9 adoption is not outpacing iOS 8 adoption because iOS 9 has a much smaller installation size. While iOS 8 required 4.58 GB to install, iOS 9 only requires 1.3 GB, making it much more accessible to users who have little space open on their devices.

There's a few ways to read that second graph. Here's mine based on my personal experience: the iOS 7 update was so painful that I am much more cautious to read others' experiences now before upgrading. That release greatly reduced my iPhone 4S performance, and I ended up not appreciating the UI changes either.

iOS 9 looks to be a good update from what I've read so far, but I'll probably wait a few more days.

Just updated this morning, I'm extremely underwhelmed. Did they add anything substantially new? I've read the release and I know they did add stuff like revamped Notes, WiFi hand off in weak signal areas, keyboard improvements, etc. But I'm not seeing anything earth shattering, certainly nothing denoting an entire number change from 8 to 9.

I like a lot of the adoption rate has to do with the amount of errors people are seeing when they attempt to download the update. I have read and heard countless people talk about the "unable to update" issue who are waiting a couple days before they do.

I would check again in a week and see what the results are

I never get the point of these stats, most people with "i" products will update to the latest firmware, even though we know it'll inevitably slow our devices. I do it as much as anything because I can't stand that little red 1 staring at me.

Interestingly I used an iPhone 3G a few weeks back, never really been used and never updated - was incredibly smooth, it's only the crappy updates that ruin the old devices...

A lot of the new stuff is only available on the latest devices, some of the coolest ones only on the latest iPad. So you'll get the most if you have an iPad Air 2 (or iPad Pro). Other devices may see a lot less new stuff, although there are a lot of under the hood stability and efficiency improvements that won't be immediately obvious.

I think iOS 9 has been triumph, I am really enjoying the performance boost. Last years version didn't add much in a front facing term.

My sights are now on El Cap which I am really looking forward to!

Is there going to be any Apple TV OS updates? Thought there was normally a beta alongside iOS?

It's "under the hood" updates mainly. And I agree, this should have been 8.5...

My guess is Apple is just trying to keep the pace of at least 1 iOS number a year... Once they get to parity with OS X, I guarantee that we'll get more "point releases" that would otherwise be "full numerical" releases.

Easily explained because of people's horrific upgrade experiences with iOS8. That screw-up is going to take a long time to forget.
Agreed. If a few days pass and no major reports come out, I expect the adoption rate to pick up a bit. A lot of us with work-sponsored iPhones have been told to wait until they test iOS 9 (probably because of what happened last year), so that could have some impact, as well.
