iOS 12 Now Installed on 78% of All Devices From the Last Four Years

Three and a half months after launch, the iOS 12 operating system is installed on 78 percent of devices released in the last four years, according to updated iOS 12 installation statistics shared on the App Store support page for developers.

Apple now presents iOS data in two ways, offering up installation rates on recent devices and older devices.


While 78 percent of all devices from the last four years are running iOS 12, 75 percent of all devices have the updated installed. 17 percent of users continue to run iOS 11, while five percent of devices released in the last four years run an earlier version of iOS.

iOS 12 was installed on 70 percent of all devices and 72 percent of recent devices as of December 4, so installation rates have grown just a few percent over the course of the last month.

iOS 12 is being adopted more quickly than iOS 11. On January 25, 2018, iOS 11 was installed on just 65 percent of active iOS devices, likely because of the myriad bugs that plagued the iOS 11 operating system over its lifetime.

Adoption rates for iOS 12 are more similar to iOS 10 adoption rates, with that operating system installed on 76 percent of active devices by January 5, 2017.

Apple's ability to quickly disseminate software updates to the majority of its user base has always given it an edge over Android, with Apple able to deliver new features and security updates in a timely manner.

Most Android users continue to use the years-old Marshmallow, Nougat, or Lollipop operating systems rather than the most recent version of Android, and many Android devices may never see updates to newer versions.

all my devices (2 iPhones and iPad Air 2) still in iOS 10 or older, so looks like I'm in last 8%.

No surprise there. iOS 12 is by far the best version in years.

I'm sure the fact that the iOS installer pre-downloads in the background and then prompts you to update with no obvious negative choice has nothing to do with it. :P

I must have deleted it on my iPad more than 10 times already in the last two months.

Not sure why one would use iOS 11 and not upgrade to 12?

False statistic again from Apple. If they quit forcing people to upgrade or allowed people to revert to a previous version those numbers would plummet.

Apple basically harass users into upgrading. It doesn't work with everyone. ;)

iPad air was nearly unusable under 11, got degraded to a fancy photo frame and the occasional iptv player. With 12 it seems to be reborn, fast, responsive, great. And better battery to boot. Best thing ever happend to it.
iPad pro 10,5 2017 got the same amazing performance then before, but lost nearly 2 GB of junk after the update, meaning I got 2GB more space.
iPhone SE never moved to 11 because of the horrible experience with the iPad air at the time. Now went from 10 to 12 and.........wow, faster then ever, even better battery life and that after 2 years.
I can see no reason to not upgrade to 12 if it is possible.

Yeah, it’s difficult to avoid and impossible to ignore.

I guess I was under the assumption that iOS 12 improved the performance and includes security updates for devices back to the iPhone 5S? I also have never had iOS automatically download on my phones or iPads so I was not aware Apple was forcing users to update software.


Then it was on under 11? I do not know 11 because it was just, well, not usable. I had it on an iPad air and was hoping it sorts itself after indexing. Had to go away and missed the point of no return (10 was not signed anymore) and was stuck with a basically useless iPad. iPhone remained at 10, so did the iPad pro. 12 comes along and all is good, way better then 11 and better (and smaller,) then 10.
Autoupdate is in settings-general-software updates-automatic updates. Disable that and no more auto updates. Simple.


I don't know about previous versions, but iOS 12 literally has an option to make updates manual and not automatic.



Which is odd ... because I tried to get as far away from iOS 11 as soon as humanly possible. iOS 12 was a massive improvement over iOS 11 performance-wise.


I just see you posted pictures. So you disabled auto update. All is fine. It gives you tho option to download and jnstall updates but is not doing it automatic anymore. So where is the probleme

There is a new option iOS 12 for automatic update installation. Unfortunately, that option only relates to installing the update basically, the automatic update download is still something that is separate and is still there without any user options to disable it.

Strictly speaking they aren't but........

* They hound you with notifications until you do.
* The phone will download updates in the background whether you like it or not, (not everybody is on an unlimited wifi connection).
* Once downloaded the messages to install are sometimes worded carefully and it's actually easy to install accidentally.
* But if your phone goes in for repair, it WILL come back with the latest OS if they wipe it. That part is surely them forcing you.

Must have deleted the update over 20 times. Run my own business and use my phone for work, if it is functional I will want to leave it that way until I'm happy to update. A borked forced install would royally p*** me off.
