Using iCloud is worth considering. With iCloud, you can Optimize Storage. Optimize Storage saves space on your phone by keeping only smaller pictures there, and relying on the full files being kept at iCloud Photos. This way you can quickly scroll through all your pictures, even though they don’t take up so much space. Then, when you need the full pictures for printing or editing, etc, the phone grabs the full file from iCloud. This is very cool. With Optimize Storage, you can save more than 80% of the storage that would be used by Photos otherwise.
