I have 200 G of iCloud storage, and all my pics are automatically stored there. For some reason I still have 4.5 G of used photo space on my phone which I want to clear up, but I am worried that they will be deleted from iCloud when i delete them from the phone. any advice?
iPhone 5s, iOS 8.3
With iCloud photo enabled, you cannot delete a photo on one device without deleting it from every device that uses iCloud photo library. In order to save space on your mobile devices (and indeed your Mac if you wish to do so) turn on optimisation for photos on these devices (settings > photos & camera > optimise storage on your mobile device and Photo preferences > optimise storage on your Mac)
Optimisation is dynamic, it reduces the resolution of your photos as and when needed, so you may not notice it occurring at first. However when it is needed, it is very effective and users have reported libraries being optimised to much less than 10% of their original size in some cases. My own library is about 9% of its original size on my phone.
Do you have "Optimize Photos" selected under Photos/iCloud?
Yes, if you delete the photos on your phone they will be deleted across all devices through the cloud.
