I have deleted all my pics including from recently deleted and i have 45GB in icloud but still my photos are taking up a lot of space even though there is nothing in the photo album. Please help urgent issue!!
I had this problem for a long time with my 16gb iPhone. After a lot of looking I discovered iExplore and this tip:
Essentially, Photos caches lots of files and due iOS bugs, the caches don't always get cleared up.
I used the solution on the above page and cleared up 2GB of space.
I am no expert but theres a few things to consider. first doing a reboot might help. second its possible a app have alot of photos for the graphics of the app. also when you delete a file (i.e. pictures) it just marks it as free space and its possible something isnt considering it as free space. i might be wrong i am not completely sure.
