It’s a camera. It genuinely feels like a camera to me after a few days of use which is not something I have experienced before.
I have always felt that iPhone cameras, and Samsung phone cameras etc, don’t quite feel like products that can capture moments in the way that real cameras can, but for the first time this feels different.
This feels like a DSLR shot to me-
Taken in very low light, almost darkness (no flash)-
Portrait mode has improved a lot as well and feels much more consistent-
Also, the extra battery life appears to have taken the iPhone passed the sweet spot for me that means I am not close to needing to charge it during the day.
To be honest little else feels improved from the iPhone X, but the camera and battery alone would make it hard to go back.
