Key Differences
-
The Xiaomi 17 Ultra has 512 GB of base storage instead of 256 GB
The spread here is large: 512 GB on the Xiaomi 17 Ultra versus 256 GB on the iPhone 17 Pro Max. Expect to notice it. The Xiaomi 17 Ultra starts with more room, which means fewer “storage full” warnings and less time deleting old videos.
-
The Xiaomi 17 Ultra has a dedicated 200 MP telephoto camera
Of all the specs we compared, this is one where the Xiaomi 17 Ultra makes its strongest case: 200 MP against 48 MP. Telephoto lenses earn their keep at concerts, school events and portraits: anywhere you can’t simply walk closer.
-
The Xiaomi 17 Ultra has a 0.53 oz lighter build
It’s a fine margin, and it favors the Xiaomi 17 Ultra (7.69 oz versus 8.22 oz). A few grams won’t matter, but bigger gaps add up in a pocket or a small bag over a full day.
-
The iPhone 17 Pro Max has a bigger top storage option
The iPhone 17 Pro Max clearly leads on max storage, and 2 TB versus 1 TB is a difference that reaches well beyond the spec sheet. Most buyers are fine with a base or middle tier, so this is a niche advantage, but a real one if you need it.
-
The Xiaomi 17 Ultra has a sharper 50 MP selfie camera
On front camera, the Xiaomi 17 Ultra posts 50 MP against 18 MP for the iPhone 17 Pro Max, a gap big enough to feel in everyday use. Front cameras are often an afterthought, so a higher-resolution sensor is a small but welcome edge for the Xiaomi 17 Ultra.
