Being cheeky and posting here for traffic!
I've upgraded to an iPhone 14 from an iPhone 11 and, since then, my iCloud storage says it's nearly full. I've got the 200 GB plan but 190GB is being used. It's a family plan but 54GB is being used by family and the rest is all me.
My old phone has been completely wiped and I've removed all previous backups. But my photos (just under 25000 of them) are about 122GB. Does that sound right for that many photos? It might be but I'm 95% certain that before I upgraded I had plenty of space left. I definitely didn't get any warnings that it was nearly full.
Is it possible that my photos have been duplicated or my old phone has stored them somewhere? I'm totally baffled!
