3. Only save HDR photos
If you have your photos automatically backed up and are deleting them then it should no longer be your space hog. You may have noticed that your phone can store two images of the same photo that’s your phone using HDR (High Dynamic Range). This happens if you have HDR on Auto or selected as always On. The camera setting is best for capturing images in low light or with shadows. Then why keep the normal photo if you wish tochoose to shoot in HDR. For changing the setting go to Settings > Photo & Camera. Scroll to the bottom and deselect Keep Normal Photo.
