By the looks of it, the new iOS does not seem able to save 30 sec exposures, but limits them to 10 sec insteadHere's a screen recording of the entire 30 Second Night Mode test with the EXIF data pulled up right after.

You are right. I was confused seeing 30s on my pictures until I realized that regular HEIC have 30s while ProRAW shows 10s. In the most cases I also have pure black pictures done in ProRAW at ISO 5000 or lower. Sometimes blue fog shows up a bit even with ISO 5000. Everything over 5000 shows red, blue or purple smudges.The IP14P's EXIF data will show 30 seconds, b/c it's a true 30 second exposure shot.
The IP15P, IP16P and IP17P EXIF data will now show 10 seconds for a 30 seconds exposure shots, b/c it's actually 3 x 10 seconds stacked together for more clarity. Apple is calling this Photonic Engine for Night Mode, Shane Mosstyn discovered it in his IP15P Milky Way video, this fixed the star trails from the 30 seconds long exposure shots the IP14P had in 2022.
I've re-done the 30 seconds Night Mode ProRAW test again just now, during the photo shooting it was showing 30 seconds.
For me this issue started since iOS 18.2, they have never solved it since then...I was testing my phone camera and noticed that subjectively pictures look better when JPEG-XL Loseless is selected. Lossy look worse.
While I was taking pictures I didn’t notice that some of them were taken on Ultra Wide camera. Interesting, but it looks like Ultra Wide camera sensor is also affected.
It's so sad, that 17 Pro/Max are having same issues, but kinda expected, since the sensors are 1:1 minus the new telephoto. 18 Pro/Max 100% will change it, since it's their turn.
There are situations (like myself), in which prior the iOS 18.2 all the 30 secs exposure photos were pitch black, no banding - how does one explain this "HW/motherboard issue"?Believe it or not, its not a senor issue. I've had this problem on a iPhone 14 Pro and it kinda ruined our Astrophotography vacation for the wife. It took the Genius Bar many repairs to resolve it, first we tried a new camera module and it didn't fix it. I had to show them NEW and real Milky Way photos with the blue banding issues I took and it took a many trips to prove it. In the end they replaced the Logic Board which is basically a new iPhone and the problem was resolve. Who knows what it is, could be an image pipeline processing or a controller and etc etc etc

LE: Also while using third party apps to take long exposure photos (e.g ProCamera), there are zero issues with banding.
Hardware issue with the logic board can explain why I can also see purple smudge even on the pictures taken with the Ultra Wide camera at ISO 6400.IP14P Era
After going through that repair for the iPhone 14 Pro, I went through hell and never wanted to go through that again.
As I mentioned before, the first step of the repair was to change the camera module and that didn't work. The next repair was the logic board and it cleared blue banding and smudge issues I had.
IP16P Era
Since I went through that hell of a repair, my first 3 iPhone 16 Pro all had the blue banding issue and each one I was within the 14 day return window. The 4th iPhone 16 Pro was the one without any Night Mode problems. People who missed their 14 day window had to do the repairs, after the 8th day all this chaos hitting the web there was a memo to the Genius Bar staff to reject all repairs regarding this blue banding issue and notify the customers to wait for a software update. The RC build of iOS 18.2 rolled out 7 days before the public release, I've loaded it up and I got the blue and giant red circle bandings like everyone else. I was able to downgrade to iOS 18.1.1, my IP16P is still on that build as of right now and all updates I've turned off.
Apple's Night Mode fix in iOS 18.2 was to put everyone on the same blue banding issue playing field and to report to all customers the camera will have some noise and it's within specs, also the tabletop night mode test is invalid. The people who had this issue in the beginning will always have it, the other people who did not have it will now have it like the rest Every thread on Apple Support, Reddit, Youtube and etc are complaints of people got this issue after updating to iOS 18.2 The percentage of users that would shoot astrophotography properly is a tiny percentage compared to how many iPhone logic board Apple needs to replace.
3rd Party Camera Apps are restricted to whatever Apple allows them to have for their API rules. For example in 2022 for the iPhone 14 Pro, all 3rd party Camera app can only shoot long exposure photos at 10 secs MAX, but they are allowed to stack 3X image to hit the 30 second exposure time, also iSO levels were capped at ISO 500 MAX. Shooting the Milky Way with any 3rd party app does not even come close to the native Camera app, even with the ones that you can stack 100s of them together. The higher the iOS level in night mode will show so much blue banding, the lower level are faint, but when you're shooting low light and Astrophotography, those levels barely have any details.
