Apple's iOS 11 installed on 59% of compatible devices, up 7% from November
According to fresh iOS 11 adoption statistics issued by Apple on Tuesday, the company's latest mobile operating system has made its way onto more than half of all supported devices since its release some two and a half months ago.

Announced in an update to Apple's developer web portal, 59 percent of compatible iPhone, iPad and iPod touch units were running a version of iOS 11 as of Monday.
As usual, Apple's statistics were pulled from iOS App Store visits, painting a more accurate picture of iOS adoption as compared to third-party estimates.
Apple's iOS 11 install base has grown significantly since the last official update in November, which showed the mobile OS on 52 percent of active devices. Apple began sharing iOS 11 adoption statistics on Nov. 6 with data gleaned from the App Store .
The developer resource notes 33 percent of devices visiting the App Store are still running iOS 10, while another 8 percent are on older versions of the OS.
Though the company does not provide day-by-day metrics, the latest iOS 11.2 release pushed out unceremoniously on Saturday, likely drew in a number of new users.
The latest iOS 11 version addresses a date bug discovered last week that causes some iOS devices to enter a soft reset loop. More importantly, iOS 11.2 delivers Apple Pay Cash, Apple's hotly-anticipated peer-to-peer payments feature. After a brief holdup, the service officially went live earlier today
Despite the reasonably strong numbers, iOS 11 adoption trails behind that of its predecessor, which was running on 63 percent of supported devices after its first two and a half months of availability.
Apple released iOS 11 in September alongside a slate of new iPhone products including the new iPhone X flagship. While not a major revision over last year's iOS 10, the new OS contains a slew of under-the-hood feature additions including ARKit, support for the high efficiency H.265 codec, AirPlay 2, Siri improvements and more.

I suspect the the lag in adopting iOS 11 is in part due to many others still relying on old 32-bit apps.
Why can't I choose my iPhone 4S iOS again ?
Actually, I'm not very impressed. As I've said before, Apple FORCES customers onto its latest version of OS-- sometimes to the detriment of the platform (looks at his iPad 2, rendered virtually useless by iOS 9.3.5, which is the ONLY OS Apple will allow me to put on it)
Similarly I have had an iPhone 4s rendered virtually unable to receive calls, as the phone application takes forever to load under iOS 9.
As long as you get lucky and don't have to restore your iPhone you'll be fine-- but any kind of OS bug that trashes your memory will force you to load the latest OS release (which is why my iPad is toast)
Ive since had many a day where battery life has inexplicably (ie no obvious app cause) been much lower in the evenings than it used to be as well as odd keyboard behaviour that I never had with iOS 10.
Also little things like the new pull up control centre not having night shift mode unless I force touch the brightness bar (so obvious Apple - not). Control centre is butt ugly too now.
The worst is swiping back on safari I often activate the task manager which is so damn annoying.
Fact : my iPhone is less user friendly with ios11
Overall im not impressed with ios11. I can’t think of a single thing it has given me which is worthy.
Sadly it’s also notorious of apple that updates really do slow down old devices no matter what the media infers. Had it happen too many times myself.
No obvious way to restore back to ios10 either. As soon as I plug the phone into my Mac it’s already doing a back up.
And don’t even get me stared on the hard push to install High Sierra I get every time I use my Mac with a dialogue box that has 2 options - Install Later or More Details.
The android model isn’t better mind but Apple’s Practices aren’t that good either.
However, my wife hates to update to major releases because the UI changes. I can keep her up to date with the "." revs, but once they went from 10.xx to 11 that's it until she upgrades her device. I paid the price a few years ago (I think when they went from iOS6 to iOS7) when the UI was totally revamped.
Last one I had was an S7 edge. Sold it and swapped back to iPhone before Samsung got the release out the door (typical to wait months after google releases a new major android version)
Android is not the holy land for sure.
Judging by ios11 neither is apple.
This is what is happening in the Apple world.
I have a few friends and colleagues that cite those 2 reasons for not upgrading.
Moreover, with the release of a new iOS, a lot of users with older devices are afraid to be stuck with a slowed down device as it has happened with iOS 9.
If apple’s policy is to have its user base on one iOS, they need to make sure each release is stable and performing, especially on older supported devices. Maybe with a cut of features.
But ios11 has been one of the worst releases so far. And as long as iOS rushed releases are inexplicably linked to hardware releases, rather than maturity of software, we are not going to see much of an improvement...
Yes, from my own personal experience, I can say that there are many Android version upgrades (Jellybean 4.3 to Kitkat 4.4 in Moto G 1st Generation in my wife's phone, Lollipop 5.1 to Marshmallow in my wife's Moto G3) which did NOT slow down the phone at all. There was an odd release from Kitkat to Lollipop (my Moto G2) which made the phone lot worser (slower, unstable etc), but that was a one-off in the last 4 years. This slow-down problem IMMEDIATELY after version upgrade is specific to iOS world only, not there in Android world. There are exceptions due to OEM customizations, but stock/near-stock Android has not degraded performance in old phones.
In my iPad Air, the situation was totally opposite. With iOS 7, it was near perfect. After upgrading to iOS 8, random restarts were the norm. But slowdown was not noticeable, if there was any. With iOS 9, it was much more stable than iOS 8 ever was, but was slow. It has come to a crawl now, after my daughter accidentally installed iOS 10.
