As a new iPhone owner, I was shocked to learn that it was missing such a basic function. Initially I just assumed that I was not able to find the correct setting due to being a brand new user, until I searched online and came across discussions such as this one.
Even ancient brick and flip phones allowed for a separate alarm volume setting, so I took it for granted for as long as I have owned cellphones and smartphones, and I definitely would have never guessed that such an expensive phone would be missing such a basic feature.
Having to change the volume every night and morning would not even be as much of an annoyance if it were not also for the fact that raising the volume also makes new text message notifications and phone calls really loud, which needlessly wake me up if someone decides to contact me at night or when I have an opportunity to sleep in. I know I could just set the phone to silent, but then I would have less to complain about. 🙂
I was even more surprised by the fact that some of the discussions on this subject are years old, yet Apple still has not done anything about this issue.
Do not get me wrong, other than this nuisance I really like the phone so far. I am mainly just curious if it is an intentional design choice, and if so, what the reasoning behind it is, or if for some reason it is not possible to implement due to the iPhone's hardware, though that would make even less sense, especially after it has been around for several generations.
