How do I free up storage on my iPhone

you can either delete unwanted photos, then delete then for good from your recently deleted album. i find that photos are a huge storage problem for me. you can also delete unused apps, contacts, and remove unused/excess browsers randomly opened in safari. if i was you, photos would be my first option.

To free storage on the iPhone, you must delete some content. Up to you what you decide to delete, but that is the only way to free storage space on the iPhone.
