I'm using Android 12 and iOS 15 at this time.
I really don't think that Windows 10/11 has any problem for getting updates comparing to Android 12 and iOS 15.
Both of those operating systems require strong internet connectivity and also continues power-on situation, which Windows 10/11 are no exceptions.
But the main difference between Windows 10/11 and Android/iOS is the quantity of updates.
My Google Pixel device receives updates once a month in the most often condition (the exact same about iOS).
But my Surface Pro as a Microsoft owned PC, receives updates much more often, at least once a week or even sometimes every 3rd day!
And the reason is so clear.
If we want to talk about Android, Google just left the x.1 or x.2 strategy since Android 9. Because they decided to set the "security patch month version" to detect if you have the latest update or not.
So you'll receive updates on your Android phone now, without changing the "Version" of it.
But iOS is just like an app! Whenever you receive any update, it'll change the "Version" of your iOS which is 15.3 now.
You won't receive update on iOS without changing the "Version" of it.
But it's totally a different case about Windows 10/11.
The current latest version of Windows 10/11 is 21H2. And it won't change even if you receive updates 100000 times until the next major update in the late spring.
It might change the Build number, but it might not!
The reason is clear.
Updates in Windows 10/11 are more in quantity because it's a PC OS.
And a PC OS which the devices using it, are so different in aspect of hardware and DRIVERS.
Yes...
If you have a Samsung Galaxy phone with Android, you're not going to receive Driver updates when Samsung wants to...
The only time you receive updates on your Galaxy, will be Google Security patches.
But imagine that you have a custom made desktop PC. In this case, your sound card manufacturer release driver updates whenever needed via Windows update, or your camera or...
Do you see?
There's a huge difference between Windows and iOS/Android.
Therefore it's so reasonable to have 10x updates for your PC during one month in compare with your phone...
If here we're talking about the behaviors and life style of users which is affecting update procedure, I should say that it's exactly the same for Windows, Android and iOS about me.
When I want to receive major updates on my Google Pixel, I prepare a strong internet connection for it, I leave its screen on, plugged in, and waiting!
This is exact same scenario for iOS and Windows.
When I want to update my iPhone from iOS 15.2 to iOS 15.3 I connect it to a strong internet connection, I turn off the automatic screen lock by inactivity, I plug it in the power cord, and I wait...
Again, this is the exact same that I do with my Surface Pro when I want to update it from 21H1 to 21H2.
But if your problem is the quantity of a Windows 10/11 PC updates, you should remember that it's a PC with weekly security and drivers updates.
Apple released iOS 15.3 only for 38 devices.
But Microsoft released Windows 10 v21H2 for millions of laptops and custom made desktop PCs, that is a "World-to-World" difference.
Don't expect to have the same experience...
