Good day! I have an iPhone 6s+ running 10.0.1 (beta GM release). I'd like to move ALL photos off of my device into the cloud. I have the cloud settings all configured (Photo stream, etc..) however, there's still over 1.5GBs of photos hard stored on my device. I'd like that number to literally be 0 and have all photos/videos stored in the cloud.
Thanks!
iPhone 6s Plus, iOS 10
Although I can't speak for iOS 10.0.1 (but in this case I can't believe there is a difference) iCloud is not simply meant to be used simply for external storage. Apple intends to be a syncing (and backup) mechanism. If you delete the photo on your device it will also be deleted in iCloud using Photo Library. However, see the section "Save space on your device" in this article:
iCloud Photo Library does not work that way. Never has.
It is a syncing service, not off device storage. It is designed to sync your photo content between each of your devices signed in with the same Apple ID.
You can reduce the amount of storage required at the device level by selecting the Optimize feature.
