Xiaomi 17 Ultra vs iPhone 17 Pro

The Xiaomi 17 Ultra and the iPhone 17 Pro cost the same, so this is one of the purest flagship decisions you can make: no price to tip the scales, just Android versus iOS and two very different ideas of what a top phone should be. Xiaomi leans hard into camera hardware and battery; Apple leans into video, sustained power and its ecosystem. Here is how they compare, drawn from independent expert reviews of each, with current UK prices.

At a glance

The Xiaomi 17 Ultra (around £1,099.00) is the camera-and-battery specialist: a one-inch main sensor, a continuous-zoom telephoto, a big screen and an enormous, fast-charging battery, running Android. The iPhone 17 Pro (around £1,099.00) is the iOS powerhouse: Apple's fastest chip, the best video tools on any phone, a more compact body and years of seamless ecosystem support. Same money, so it comes down to platform and what you shoot.

Operating system

This is the first and biggest question. The Xiaomi 17 Ultra runs Android with Xiaomi's HyperOS, which is fast and heavily featured; the iPhone 17 Pro runs iOS, simpler and tightly linked to other Apple devices. Choose the ecosystem you already use — it shapes daily life with the phone more than any single spec. Both receive years of updates.

Design and build

They are sized differently. The iPhone 17 Pro is the more compact and lighter phone, in an aluminium unibody at 206 g and 8.8 mm thick, built around a 6.3-inch screen and housing a vapour chamber for cooling. The Xiaomi 17 Ultra is larger, measuring 162.9 x 77.6 x 8.3 mm and 218.4 g, built around a bigger display. Both are premium and IP-rated. If you want a pocketable phone the iPhone wins; if you want the bigger canvas the Xiaomi does.

Screen

Both use excellent OLED panels at 120 Hz. The Xiaomi 17 Ultra's is larger at 6.9 inches and claims a very high 3500 nits of peak brightness. The iPhone 17 Pro's 6.3-inch display is smaller but superb, measured at around 2507 cd/m² in testing. Both are easily readable in sunlight; the Xiaomi gives you more screen and higher peak brightness, the iPhone a more compact panel.

Performance

Both are as fast as phones get, from different camps. The iPhone 17 Pro runs Apple's A19 Pro chip with a vapour chamber that holds performance under sustained load. The Xiaomi 17 Ultra runs the Snapdragon 8 Elite Gen 5 with 16 GB of RAM and storage up to 1 TB. In everyday use both feel instant; the iPhone's chip and cooling give it an edge in long, heavy workloads, while the Xiaomi counters with more memory and huge storage options.

Cameras

This is where they diverge most, and both are exceptional. The Xiaomi 17 Ultra is a photography flagship first: a 50-megapixel one-inch main sensor for outstanding light-gathering, a 50-megapixel ultra-wide, and a standout 200-megapixel telephoto with a continuous mechanical zoom that glides smoothly through its range. The iPhone 17 Pro runs a triple 48-megapixel system — a 24 mm main, a 13 mm ultra-wide and a 100 mm (4x) telephoto — and its trump card is video, filming in Dolby Vision and capturing professional ProRes RAW on every lens. For still photography and zoom, the Xiaomi's one-inch sensor and continuous zoom are hard to beat; for professional video, the iPhone leads clearly, while the Xiaomi's Leica-tuned processing lends its stills a distinctive, rich character.

Battery and charging

The Xiaomi has a decisive advantage. It packs a large 6000 mAh battery and charges at 90 W wired plus 50 W wirelessly, so it lasts well and refuels fast. The iPhone 17 Pro's European model carries a smaller battery — a nominal 3998 mAh — and charges more slowly over a cable, with wireless charging up to 25 W. Both last a day, but the Xiaomi lasts longer and tops up far quicker; on endurance and charging it is in a different league.

Price and verdict

At the time of writing both the Xiaomi 17 Ultra and the iPhone 17 Pro are around £1,099.00, so price will not decide this — it is purely about platform and priorities.

Buy the Xiaomi 17 Ultra if you want the most ambitious camera hardware and battery in an Android phone: the one-inch sensor, the continuous-zoom telephoto, the bigger screen and the enormous, fast-charging cell. For stills, zoom and stamina, it is superb.

Buy the iPhone 17 Pro if you want iOS, the best video capture of any phone, the fastest chip with sustained cooling, and a more compact body within Apple's ecosystem. Both are outstanding and cost the same; pick your operating system first, then weigh the Xiaomi's camera-and-battery strengths against the iPhone's video and polish.
