Is the only way to save space on your iPhone, if you want to keep your photos, to plug it into a MacBook using USB, transfer the photos One by one then delete from the phone? Is there an easier way? I've tried iCloud auto upload but that seems to delete your photos from iCloud too if you delete from your phone. Can you use wifi to automatically transfers old photos to the MacBook whenever it's turned on? Is there an app that does this?
