no IR blaster (was present in Mi5)
no Gorilla Glass (mi5), screen will scratch someday, better protect
no optical image stabilisation (mi5)
pros
slighly bigger battery
very good screen and backlighting (min. 1.1 nits, max 600nits, 95 percent NTSC color gamut)
no more glass casing, but fully metal
better camera, but not great in low light
SD821
a few steps forwards but also a few big steps backwards from older gen mi5 phone.
