Apple today updated its iOS 15 installation numbers for the first time since iOS 15 was released in September, giving us an idea of how many devices are running the latest update four months after it launched.

iOS 15 is installed on 72 percent of all iPhones introduced in the last four years. 26 percent of devices continue to use iOS 14, and two percent run an earlier version of iOS. When counting iPhones released more than four years ago, 63 percent of them run iOS 15, 30 percent run iOS 14, and seven percent run an earlier version of iOS.

Installation numbers are lower on the iPad. 57 percent of all iPads introduced in the last four years are running iPadOS 15, while 39 percent continue to run iPadOS 14. Four percent run an earlier version of iPadOS. Counting all iPads, including those released more than four years ago, 49 percent of devices are running iPadOS 15, 37 percent are running iPadOS 14, and 14 percent are running an earlier version of iPadOS.

Apple splits its installation numbers into separate groups because there are still devices in the wild that are not capable of running iOS 15 or iPadOS 15, but even when counting only devices released in the last four years, the number of devices running iOS 15 lags behind prior operating system installation rates.

iOS 14, for example, was installed on 81 percent of iPhones released in the last four years in December 2020, marking a much higher update rate a month earlier. Even iOS 13, another update that saw slow installation, was installed on 77 percent of devices by the end of January 2020.

iOS 15 and iPadOS 15 had several features that did not arrive as expected when the operating systems launched, such as SharePlay, and Digital Legacy, and other features like iCloud Private Relay remain in beta. People were also put off by Apple's anti-CSAM measures, which have been indefinitely delayed. Key iOS and iPadOS 15 features like digital IDs in Wallet and Universal Control are still unavailable, but could spur people to update when launched in the future.

When iOS 15 was first launched, Apple did not spur people to update and allowed them to remain on iOS 14, offering a choice between iOS 14 and iOS 15 in the Settings app. This could also be a reason why iOS 15 adoption has lagged behind adoption rates of earlier operating system updates, and Apple is now pushing iOS 14 users to upgrade to iOS 15.

iOS 15 used to be listed as an optional update on devices running iOS 14, but now it is front and center on devices that still have iOS 14, and it is the only available update option as Apple has now stopped making security updates available for devices running iOS 14. Those who want the latest security fixes need to upgrade to iOS 15, as all devices capable of running iOS 14 also support iOS 15.

This is exactly why.
If given a clear option to update or to not, a lot of customers just won’t, because they think it’s gonna change everything.
If the phones just automatically update, then of course there’s going to be higher numbers

If I had to choose a cause for the lagging rate of adoption, I'd say it's the combination of the ability to remain on iOS 14, a broader spread of device generations in the wild compared to past iOS launch periods, and Apple's current reputation for terrible software QA.

Personally, my iPhone is on 15 but I have two iPads and two iPod Touches that are too old to run 15 (I would update them if I could).

Honestly, I've stayed on iOS 14 because I prefer the older cartography on Maps. ;)
Really? Maps in iOS 15 has come a long way. Apple maps continues to get updated by Apple. I'm sure there is more cities roll out on the line in the future. Check it out!

I once read an article about how not updating can sometimes be a security risk so I always update out of caution. My nephew and nieces have their Macs on various older versions of macOS because updating is seen as a hassle as they generally don't want downtime when they're using their Macs and they don't see the point. My mum wouldn't know when a new version of the OS on her iPhone is out and clicks 'no' to everything (better than clicking 'yes' to everything I guess?) so if it's not automatic chances are she won't be updating either.

I’m lovin’ iOS 15 on the device I have it installed, especially the new Safari design, and the tab groups, synced everywhere instantly. The Focus mode, however, I haven’t been able to take advantage of it, I keep using just the Do Not Disturb mode. And once Privacy Relay gets out of beta, I’m sure it will add a lot of value.

I’m holding on until iOS 15.3 (and macOS 12.2) to update all my remaining devices.

Oh that's interesting.
I was just lamenting on the progress Maps has made since initial launch. Barring a few missteps trying to find some obscure locations back in the day, Maps has always been rock solid for me. I've never felt a need to leverage another digital Mapping tool/app. But, to each their own. Best!

I had to update my X to iOS14 when I bought my S6 watch. I waited until a few versions of 15 had come out before updating and it's been as good as iOS14 with a few new bugs but it also fixed a few bugs I had in iOS14 so I'm happy with it. iPad stayed on 14.8.1 as I don't like the UI that iPadOS15 introduced..

Do we have data on the number of users that enable auto updates vs. those that manually manage?
I'd be interested to know.

I fall in the latter: prefer manually managing my software updates. I just like knowing what I'm installing as opposed to letting that happen in the background. Helps me feel more connected to the experience. That said, almost 100% off the time I update within hours of availability. 😜

Strangely I'm still yet to be prompted/nagged to install iOS 15 on my devices with 14.8.1. No notifications or badge on Settings. Today makes a month since 15.2 as well.

I held off iOS15 on my iPhone X at launch due to all the bugs that were widely reported. Are they pretty much gone with iOS15.2?

Oh nice. How are you liking the watch? What config did you get?
44mm 6, GPS. The very small change in screen size from my 42mm series 3 is noticeable. It's faster, the screen is nicer (and not scratched to hell), and it has enough storage that I can actually install other apps and test them out! Plus, I've been thoroughly enjoying testing out the new health and wellness features. I'm quite happy with the upgrade.

I went from s0 to s5 and it was like moving from a CRT to a flatscreen. I'm pretty careful with my tech and yet managed to place a pretty decent scratch on that screen within the first month of owning. To be specific, I believe it was my dog's claw - which I did not realize was harder than diamond. 😂
