iPhone 16 pro Exchange due to Phone Storage

Hi bro. I am using 128 gb 16 pro model. I bought the phone on October 4. In 1 month, my phone space is 50 gb. I transferred my required documents and photos into new phone.

My concern is that just 20 photos are occupying 4 GB, and the Apple Music app is 5 GB now. I am really worried that it is taking lots of space.

Do you have insights on this? I am a photographer, i will take many photos and edit so i am worried about it.

Is there a way to get 256gb variant bro?

hello bro, did you check recently deleted album in photos app and deleted any content permanently? because 20 photos 5GB is not normal. meta data of the photos shows that matching 5GB in size?
