hi I have activated the iCloud photo library and the photos occupy about 3 gig of the 5 provided for free, but I realized that going on free space iPhone that the photos occupy the memory there, where is the convenience as I do to remove all the photos and leave them only on iCloud and remove them from the cell as I said the photos loads correctly on icloud funIona all right! it is normal that the photos occupy the memory even on the phone even if they are on iCloud?
iCloud (and iCloud Photo Library) are NOT off site storage services - they are syncing services to keep multiple devices with identical content - any change made on any device (or iCloud.com) - Addition, deletion or edit - is made on all devices - for devices with limited storage you can use optimized photos to reduce storage (but not totally eliminate it) on that device -- you need to increase your iCloud storage or you risk losing photos - iCloud storage plans and pricing - Apple Support - this may help but unless you purchase more storage your will lose things - Manage your iCloud storage - Apple Support
you can NOT remove the photos from any device without removing from all devices
