I’m trying to use YouTube and it says I don’t have enough storage how can I add more storage to my phone

I would like you to realize and know one important thing and that is that there is NOTHING that you can do to increase the physical storage capacity of your iPhone. Your iPhone's storage capacity will forever remain the same as the day you bought it. You will have to delete data on your iPhone to create free space. Media files take up the most space and therefore it is a good idea to begin deleting Photos/Videos and music first.

You can purchase 👉 iCloud Storage from Apple where you create and save your iPhone backups and synch (Not Store) your Messages, Photos, Contacts, Calendars, Notes and Reminders. Note that iCloud Storage is NOT an extension of storage capacity of your iPhone. Just wanted you to know some facts.

Having said that, you can choose to Optimize Storage on your iPhone for all the Photos. What this action will do is store your original quality photos on iCloud and a small size photo on your iPhone. This takes up less space on your iPhone while maintaining the actual size on iCloud. This will free up space on your iPhone while making good use of iCloud. If you would like to try this then open Settings ➔Photos ➔ Optimize iPhone Storage : Ensure that this option is chosen and has a checkmark on it.
