Hi all, My wife and I are currently using iPhone 5s 32Gb. Our phone storage got full (mostly photos) and so we have subscribed iCloud 50Gb plan, and enabled iCloud Photo Library with "Optimize iphone Storage" on. My wife had >20Gb photos (and videos actually) and a few Gbs apps before. After subscribing the 50Gb plan, photos storage in the phone is largely reduced, leaving her a very nice ~10Gb free space. Although my phone has a different distribution of storage of photos and apps, the iCloud subscription also leaves me ~10Gb free space. So I guess "Optimize iphone Storage" would target at a certain level of free space. Is this correct? My question is, we are now thinking to buy a new iPhone for each of us. I am wondering what would happen if we buy the 16Gb model? Would "Optimize iphone Storage" further reduce the photo storage inside the phone in order to keep the free space at a certain level? If so, how much free space would it be? Sorry for my poor English. Thanks for reading!
