I have an iPhone 11 128GB with around 30GB of used storage. Most of the photos are uploaded up into 200GB iCloud which is full at the moment.
I got an iPhone 12 and transferred data & settings over from iPhone 11, device to device as described here https://support.apple.com/en-us/HT210216. The transfer itself took around ~30min.
What I ended up with, is an iPhone 12 with 122GB of storage is use, photo library taking around 90GB of it. My assumption is that for whatever reason a LOT of the photos from iCloud got stored locally on iPhone 12. The phones have same amount of photos in the libraries.
How can I get rid of the photos that that are currently LOCAL on iPhone 12, while they are living in the iCloud (uploaded from iPhone 11)?
