I’ve trawled the web for info on iCloud Photo Library’s “Optimize Phone Storage” option on iOS, but can’t figure out the exact logic applied.
From Apple:
iCloud Photo Library will automatically manage the size of your library on your device, so you can make the most of your device’s storage and access more photos than ever
I assume the device will cache high-res photos up to a point, but what is this point in terms of MB remaining on the device?
In addition, does iCloud Photo Library perform any housekeeping on that cache, e.g. clearing out high-res copies you’ve not viewed in n days – if so what is n?
