Key Differences
-
The Xiaomi 15 Ultra has 512 GB of base storage instead of 256 GB
The Xiaomi 15 Ultra clearly leads on base storage, and 512 GB versus 256 GB is a difference that reaches well beyond the spec sheet. If you shoot a lot of video or keep music and maps offline, base storage is one of the specs you’ll feel most over the years.
-
The Xiaomi 15 Ultra has a dedicated 200 MP telephoto camera
On telephoto camera, the Xiaomi 15 Ultra posts 200 MP against 48 MP for the iPhone 17 Pro, a gap big enough to feel in everyday use. A higher-resolution telephoto keeps more detail when you zoom, and gives the Xiaomi 15 Ultra a stronger tool for portraits and distant subjects.
-
The Xiaomi 15 Ultra has an extra rear camera
This is one of the widest gaps in the whole comparison: 4 for the Xiaomi 15 Ultra versus 3 for the iPhone 17 Pro. More cameras help most when each covers a different view, so check the table to see what the Xiaomi 15 Ultra’s extra lens adds.
-
The iPhone 17 Pro has a 0.71 oz lighter build
Small gaps can still matter over time, and here the iPhone 17 Pro leads 7.27 oz to 7.97 oz. Weight shows up every time you hold the phone above your face in bed or type one-handed for a long stretch.
-
The Xiaomi 15 Ultra has faster 80 W wireless charging
The iPhone 17 Pro lists 25 W; the Xiaomi 15 Ultra comes in at 80 W. That’s not a rounding error. If you rely on a wireless pad at your desk or bedside, the Xiaomi 15 Ultra refills quicker there.

Display
Xiaomi 15 Ultra leads
In the display category, the Xiaomi 15 Ultra is a step ahead rather than a leap ahead. The Xiaomi 15 Ultra brings 13% sharper pixel density. Higher pixel density keeps text and fine detail crisper, although the benefit shrinks once both panels are already sharp at normal viewing distance. For anyone who cares most about display, the Xiaomi 15 Ultra is the safer choice.
Screen size
iPhone 17 Pro: 6.3 in Xiaomi 15 Ultra: 6.7 in Screen size is personal. If you watch a lot on your phone, the extra area pays off; if you text one-handed on the go, compact is kinder.
Pixel density
iPhone 17 Pro: 460 ppi Xiaomi 15 Ultra: 522 ppi The Xiaomi 15 Ultra packs its pixels more tightly, which shows most in small text, fine patterns and zoomed-in photos.
Performance
Too close to call
This area ends level; whatever separates these two, it isn’t performance. Neither phone gives you a reason to choose it on performance.
CPU cores
iPhone 17 Pro: 6 Xiaomi 15 Ultra: 8 Treat the core count as background information; the chipset name tells you far more about real performance.
Memory & Storage
Xiaomi 15 Ultra leads
The Xiaomi 15 Ultra is the clear pick if memory & storage is what you care about most. The Xiaomi 15 Ultra comes with 512 GB of base storage instead of 256 GB. The Xiaomi 15 Ultra starts with more room, which means fewer “storage full” warnings and less time deleting old videos. The takeaway: on memory & storage, the Xiaomi 15 Ultra is the stronger phone.
Base storage
iPhone 17 Pro: 256 GB Xiaomi 15 Ultra: 512 GB Base storage is what you get without paying extra. Photos, videos and apps add up quickly, so more space at the entry price is real value.
Camera
Xiaomi 15 Ultra leads
Few areas are as clear-cut as this one: the Xiaomi 15 Ultra leads the camera section with room to spare. On the Xiaomi 15 Ultra, you get a dedicated 200 MP telephoto camera. A dedicated telephoto camera captures distant subjects and portraits without heavy cropping, which keeps detail intact. So if camera tops your list, lean toward the Xiaomi 15 Ultra.
Telephoto camera
iPhone 17 Pro: 48 MP Xiaomi 15 Ultra: 200 MP Telephoto lenses earn their keep at concerts, school events and portraits: anywhere you can’t simply walk closer.
Rear cameras
iPhone 17 Pro: 3 Xiaomi 15 Ultra: 4 The count alone doesn’t guarantee quality, but the Xiaomi 15 Ultra gives you more lenses to choose from.
Battery & Charging
Xiaomi 15 Ultra leads
The iPhone 17 Pro keeps it close on battery & charging, yet the Xiaomi 15 Ultra holds a small lead. The Xiaomi 15 Ultra gives you faster 80 W wireless charging. Faster wireless charging makes a pad or stand more practical as your main way to top up. Prioritize battery & charging, and the Xiaomi 15 Ultra is where you should land.
Wireless charging
iPhone 17 Pro: 25 W Xiaomi 15 Ultra: 80 W Wireless charging is usually slower than a cable, so this edge matters mainly to people who value the convenience.
Software & Updates
For software & updates, the differences are in the specifics (component names and types), so the table is the place to look.
