Some comments on this.....
I have the % whilst charging on mine and I'm not on an iPhone 14 yet, so cannot be 'dynamic island exclusive' as you incorrectly state.
With regards to volume, I use the side buttons, so does it need to be on the player too?
The notifications are scrollable, same is before where you had more that went over a screen. Notifications on my one goes up to the widget section. (It's nothing to do with wallpaper, like you claim, by the way)
I'm not noticing the battery percentage while charging, it should show up as you wake the screen while plugged in and then disappear, but for me it doesn't show up. I think maybe this shows up if you use certain widgets that have shorter text or something, I don't know, but I don't think it matters. I usually glance at that percentage to check how far the phone charged up, but the funny thing is the phone charges so quickly that it has never happened that I glance at the percentage and it is anything less than 80% so I think Apple may have sacrificed this because it doesn't really matter. Anyway, I realized that I don't miss it, if anything it turns out it was a nuisance because I had the need to check as I know the percentage is there, but it never mattered.
Regarding notifications, yeah, Apple sort of prioritizes the wallpaper at first, but you can scroll up and then the notifications take up half of the lock screen, which is enough. Apple split it 50-50 between the widgets and the notifications, which I think is fine. For me it would make more sense if the notifications started immediately below the widgets instead of at the bottom of the screen, but that's about it, not a big deal.
There are some changes for the sake of changes, but overall I have to say iOS 16 is my best iOS experience so far. There are some bugs in certain apps, but all minor. The important thing is that the OS is smooth, there's very little stuttering, no battery drain, phone charges up quickly, never gets hot, and the changes they made in iOS are nice, animations are more fluid and overall just look better and are applied to more aspects of the system, so all in all, even at this very early stage, I am very happy with how it all works and feels.
A bit off topic, but the same goes for watchOS 9 on my S4. Very nice so far, they added features, notifications, it's all nice and fluid, I really like Apple's software game at the moment, I don't know when was the last time my devices felt so smooth on a new OS release, and it's not like I have new devices either. Kudos to Apple so far, I just see plenty of "little things" all over the OS.
