Users still not upgrading to iOS 15 as quickly as iOS 14
Estimated user data shows almost 21% of active iPhone users have upgraded to the new iOS 15, but that's behind the number who moved to iOS 14 over the same period last year.

Initial figures from research firm Mixpanel, showed that about half as many users updated to iOS 15 during its first two days, compared to iOS 14 in 2020. By September 22, 2021, it was believed that 8.5% of users had updated to iOS 15, compared to 14.5% going to iOS 14 in its first two days.
Now Mixpanel has released data covering iOS 15's first two weeks. The company's data is based on analysing the devices of visitors to its websites, and estimates that 20.74% of traffic is coming from iOS 15.
In comparison, iOS 14 had 40.51% adoption by its second week.

At present, Mixpanel reports that 73.48% of users are on iOS 14, and 5.78% are on older versions.
Apple is already preparing iOS 15.1, and the first developer betas of it have been released. It's expected that the update will fix some of the many bugs found in the initial iOS 15 release.

and I bet the apple music offline 15 seconds and then stop bug for downloaded music that has been floating around for 8 months isn’t smitten either.
We are all free to draw our own conclusions as to the reasons behind the apparent proliferation of bugs surfacing in new releases. Having come from a software development background I heavily suspect with a very high degree of confidence that these issues are rooted in the accumulation of technical debt.
The key word is accumulation. All software has “bugs” and new bugs are always being introduced as new code is added. Technical debt is the entirety of bugs, or more accurately defined: anomalies, that exist in the code base. Anomalies include coding errors that lead to crashes and hangs but also includes features that don’t work exactly how the requirements stated that they should work as well as architectural issues, for example, hard coding in something that should be in a separate module. In essence, technical debt is a promise that the development team is making that allows them to move forward with immediate concerns while acknowledging that they own anomalies that they will “pay off” sometime later.
Like any loan, especially student loans, the owner of the loan doesn’t always follow through and pay off the debt. If the software team doesn’t clear their technical debt it accumulates over time and sometimes gets worse because it gets in the way of new code. Why do they allow technical debt to accumulate? Because there are typically more anomalies than the team can remove AND still have time to release new software features. Yes, that’s the reality of the situation. The debt accumulates and new software releases keep going out the door. But consider the alternative. Can you imagine Tim Cook or any other tech product leader getting up in front of an audience at a keynote and announcing “Our next iOS release will have zero new features, we’re just going to clear out our technical debt backlog and get all of the bugs out. Yay.”
No, I can’t imagine that happening either.
As for getting a new phone? Maybe next year.
Only issue I have - selecting text in this web forum editor doesn’t work as well. But, I’ve experienced several issues with this web forum over the years.
of course my new 13 has iOS 15 preloaded.
You're joking, right?
