Freeing Up Space on iPhone Photo Library
I must admit I find the way Apple handle iCloud and photo libraries really confusing.
Currently I have only 2.8GB of available storage on my iPhone and want to free up some space. So if I go to Settings>General>Storage & iCloud Usage>Manage Storage (under Storage), it tells me that Photos & Camera is using 893MB of space.
Yet.
If I go to Settings>Photos & Camera, it is set to iCloud Photo Library and Optimise iPhone Storage and Upload to My Photo Stream are all enabled.
Doesn't that mean that all my photos and videos should be stored in iCloud and that therefore my Storage should be 0 (or near enough), not 893MB?
I've tried deleting photos and deleted about 100 old and new (I don't take photos often so new means about a month ago) but this doesn't seem to be making any dent in the 893MB (and yes I deleted them from the recently deleted folder).
Is this how it's meant to work or is it possible to recover that 893MB?
