As the title says iCloud Photo Library on my iPhone 7 wants to re-upload all my images and videos (5348 items). I have 200 gigs iCloud storage with Photos taking around 60 gigs and I have Download and Keep Originals enabled. It says Uploading 5343 Photos at the bottom. The strange thing is that the phone really uploads something (checking my router's traffic monitor) but my iCloud Storage remains the same. It happened right after I took a few shots. It also happened around 10 days ago (re-uploading all Photos) and it took two days while draining the phone even in standby. But it also happened with my iPhone 6 several times so I'm really clueless. Is it doing some kind of consistency check? It's getting very very annoying now.
