Oppo Find X9 Ultra vs Xiaomi 17 Ultra

Oppo Find X9 Ultra

A 6.8-inch LTPO OLED with up to 144Hz and very high real-world brightness — among the brightest screens on any phone outdoors.

• 6.8-inch LTPO OLED panel up to 144Hz, with a maximum brightness around 1,800 nits and dimming as low as 1 nit.
• Hits a staggering ~3,600 nits of peak HDR brightness, making it incredibly easy to see and edit shots in direct sunlight.
• In manual mode the display peaks at 840 nits, rising to ~1,156 nits in auto on a 75% white patch and up to ~1,932 nits in the native gallery app.
• The smoother 144Hz panel and 3,600-nit brightness outperform Samsung's display.

Xiaomi 17 Ultra

A 6.9-inch 1.5K LTPO AMOLED rated at 3,500 nits peak. Measured brightness is strong on small patches but middling full-screen, and one long-term user was pleasantly surprised by it.

• 6.9-inch M10 OLED LTPO flat display at 1.5K resolution, 120Hz, with up to 3,500 nits peak brightness, HDR10 and Dolby Vision.
• In automatic brightness the screen measured over 1,100 nits, rising to over 3,600 nits on a small patch of the screen.
• Manual full-screen white brightness reached only 675 nits in controlled testing — well below the headline peak figure.
• The display surprised one long-term user in a positive way — not at the level of the Pixel 10 Pro's panel, but still rather good.

Oppo Find X9 Ultra

The reason to buy it. A Hasselblad-tuned quad system with the most versatile zoom on any phone, a true 10x optical periscope and an optional 300mm Hasselblad teleconverter. Near-universally praised, with only minor sharpness and ultrawide caveats.

• A 200MP main, 200MP 3x telephoto, 50MP 10x optical telephoto and 50MP ultrawide, all Hasselblad-branded — camera-first overkill in the best way.
• Consistently great photos, sharpness and dynamic range with really good color calibration — this phone did basically everything right in the camera department; an incredibly well-rounded smartphone camera.
• Is this the best camera phone ever built? — my new favorite camera phone and one of the best Android phones I've ever used.
• Even after a direct shootout, still the best camera phone I've ever used.
• Detail is very good, but sharpness remains a bit underwhelming on the main camera.
• The ultrawide is probably the weakest part of the setup — with the first three cameras taking so much space, Oppo reused the Samsung GN5 sensor here.
• Night-mode processing — color, contrast and exposure handling — is so much better than the Galaxy S26 Ultra's, and the ultrawide is now one of the best for detail preservation.
• The optional 300mm Hasselblad teleconverter delivers ~13x (300mm) optical-feel zoom that retains real telephoto sharpness, extending to ~60x (1380mm).

Xiaomi 17 Ultra

The reason this phone exists. A 1-inch LOFIC main sensor and an industry-first continuous mechanical optical zoom put it at or near the top of the smartphone camera rankings — but JPEG processing and a steep learning curve divide opinion.

• The 17 Ultra keeps a 1.0"-type main sensor while most makers go smaller; its main camera is quite probably the best of its kind and the phone is among the best for taking pictures currently on the market, possibly the best.
• It combines two technologies not seen together in mobile before — a 1-inch LOFIC sensor in the main camera and a mechanical periscope with continuous optical zoom — reducing ghosting and capturing highlights and shadows in a single exposure.
• Camera kit details: 23mm 50MP 1-inch main at fixed f/1.67, a 200MP 75–100mm true mechanical optical zoom (not a digital crop), and a 14mm 50MP f/2.2 ultrawide.
• This is one of the best camera systems ever used on a smartphone, as was the 15 Ultra.
• The sensor is excellent, but Xiaomi's automatic JPEG post-processing is an absolute disaster, and distant faces can look like paint blobs.

Oppo Find X9 Ultra

A standout — arguably the best video on any Android phone, with O-Log, custom LUTs, 8K30/4K120 Dolby Vision across lenses and strong stabilization.

• Stabilization is excellent — this might take the crown of the best video on an Android phone, and the cameras are way ahead of the Pixel and S26 Ultra.
• Every rear lens can shoot 4K 120fps or 8K 30fps Dolby Vision.
• Oppo extended O-Log on the X9 Ultra with custom LUT imports, real-time monitoring previews and a much more flexible professional adjustment range.
• You still notice minor micro-jitters when filming at night, so be a little mindful, though skin tones and dark-to-bright exposure transitions hold up well.

Xiaomi 17 Ultra

Serious video credentials — 4K120 Dolby Vision and log across the main and periscope sensors — undercut by odd software gaps and processing inconsistency.

• Records 4K up to 120fps on the main and telephoto cameras, with Dolby Vision and log available for color grading.
• All three lenses support 8K, but the ultrawide can't do 4K120, and despite 4K120 support the slow-motion menu only goes up to 1080p — odd software limitations.
• A reviewer judged the iPhone 17 Pro Max the better of the two for video — the Xiaomi's footage is sharp 4K but a touch oversharpened and more contrasty.
• Third-party pro apps like Blackmagic Camera and MotionCam Pro only get a fixed ~78mm field of view with no optical zoom range, making the mechanical zoom useless in a professional workflow.

Oppo Find X9 Ultra

Snapdragon 8 Elite Gen 5 puts it near the top of the benchmark charts, but sustained-load stability is mediocre and Oppo deliberately throttles early to control heat.

• As expected, the Find X9 Ultra earns excellent benchmark scores near the top of the charts.
• A 3D ultrasonic fingerprint scanner Oppo claims is 35% faster and 33% more reliable, plus vapor cooling to dissipate heat through the aluminium frame for better sustained performance.
• 3DMark returned ~7,530 best-loop and ~3,682 low-loop with only ~49% stability, and peak performance didn't last a minute — weak sustained behaviour.
• Genshin Impact stayed consistently above 50fps and remained smooth even when throttling to ~30fps after ~16 minutes at 41.5°C, at under 4W power draw.
• Honor of Kings averaged 144fps over 30 minutes at max settings; Genshin held max 60fps before stabilizing near 50fps.

Xiaomi 17 Ultra

Snapdragon 8 Elite Gen 5 keeps it firmly in the flagship tier with strong gaming, though sustained behaviour and thermals draw mixed verdicts.

• The Snapdragon 8 Elite Gen 5 brings ~20% faster CPU, ~23% faster GPU and peak speeds up to 4.61GHz over the previous generation.
• The iPhone has a slight single-core edge but the Xiaomi takes the lead in Geekbench multi-core.
• Genshin Impact at very high settings ran 30 minutes at an average of 55.3fps with a 1% frame drop, while lighter titles like Honor of Kings averaged 107.8fps; both front and back stayed around 40°C.
• It delivered significantly better gaming performance than the Xiaomi 17 Pro and performed better in the stress test than the 17 Pro with the same 16GB of RAM.
• Delta Force ran for 23 minutes straight with impressive thermal management and no notable heating.

Oppo Find X9 Ultra

A genuine highlight: a 7,050mAh silicon-carbon cell that posts some of the best endurance numbers of any 2026 flagship, with fast 100W wired and 50W wireless charging.

• Draws power from a 7,050mAh battery — a sizeable increase over the previous generation — with 100W SuperVOOC wired and 50W AirVOOC wireless charging.
• Earned an active-use battery score of over 20 hours; with the SuperVOOC charger it went 0–75% in 30 minutes and to full in 45 minutes.
• After ~10 hours of continuous use starting at 7am it still had 53% battery, regularly getting 8–9 hours of screen-on time and ~40% left after a 13-hour day.
• A PCMark synthetic loop returned 15 hours 2 minutes, and 100W SuperVOOC charging took ~49–52 minutes (the charger isn't included).
• With moderate usage you can easily expect more than 2 days of battery life — Oppo finally feels like a truly complete product.
• Charges 0–100% in about 52 minutes on the official 80W charger in a head-to-head charge test.

Xiaomi 17 Ultra

The single biggest divide in the coverage: lab tests record an excellent active-use score, but the global model's smaller battery, ~10%/hour real-world drain and heat make endurance inconsistent. Charging stepped down to 90W wired / 50W wireless.

• The global 17 Ultra earned an excellent active-use battery score of over 19 hours, charging 0–70% in half an hour and to full in just 43 minutes.
• After 3 months a user still had around 45% battery left at the end of the day when not using the camera intensively.
• For a 6,000mAh battery, ~4 hours of screen-on time over a full day was disappointing — the S26 Ultra's 5,000mAh cell matched or beat it under the same camera-and-navigation use.
• In a head-to-head extreme test the 17 Ultra ran hotter and lost more battery than the OnePlus 15 and Oppo Find X9 Pro at nearly every stage, finishing about 8 hours 8 minutes at 43.7°C.
• The global model holds ~800mAh less than the China version and drains roughly 10% per hour, so it can't last a full 15-hour day the way the China version does.

Oppo Find X9 Ultra

ColorOS 16 has matured a lot and is fast and smooth, but it still trails Samsung and Google on AI depth and feels iOS-derived to some — the phone's clearest weak point relative to its hardware.

• ColorOS 16 feels like one of the best versions yet.
• It's a good Android experience but not on par with the Galaxy experience for AI features and tool integration, and portrait autofocus struggles in some low-light conditions.
• For me it's the best version of Android I've ever used — light, fast and smooth with no major issues.
• The hardware is superior to the latest Samsung, but the software feels like an imitation of iOS.
• With a bit of tweaking and updates, Oppo's software and camera engineers can make this even better — there's clear headroom.

Xiaomi 17 Ultra

The phone's most consistent weakness. HyperOS is widely seen as not up to par with the hardware, with camera-app limitations and an iOS-clone feel — though a minority of long-term owners disagree.

• The 17 Ultra perfectly embodies a great camera held back by software — the HyperOS interface is seriously lagging and not up to par with the rest of the phone.
• Android Police's verdict: the best camera phone of 2026 has a serious problem.
• Camera-app software limitations frustrated reviewers — quick-launch buried in gesture settings and the ultrawide preview looking awful.
• After 3 months one owner called HyperOS 3 one of the best versions of Xiaomi software they've used, with 6 years of security support.
• Even fans note HyperOS hasn't visibly evolved in years and Xiaomi should work on the software more.

Oppo Find X9 Ultra

Premium-priced and hard to buy in many markets, but reviewers broadly conclude it out-cameras the S26 Ultra and Pixel and edges the Vivo X300 Ultra on usability.

• Its main compromises are the ~€1,699 price, large 236g body, occasional software concerns and limited availability in some markets.
• It feels like Oppo wanted to make the camera first and just happened to also create the best Android phone you can get right now — though it won't win every year-end award.
• The base Find X9 Ultra starts at 7,499 yuan in China — roughly £814 / ~$1,100 — but the heaviness and visual pressure are the first impression.
• The closest rival is the Vivo X300 Ultra, but the X9 Ultra wins by having a more user-friendly OS.
• The Hasselblad alliance delivers a phone that genuinely challenges the Galaxy S26 Ultra on cameras.

Xiaomi 17 Ultra

A premium price for a premium camera. Reviewers agree the hardware is exceptional but increasingly question whether the global price and software make it the right buy versus the cheaper Xiaomi 17 or rivals.

• The 17 Ultra starts from £1,299 / €1,499 (about $1,750) globally, with the limited Leitzphone at £1,699 / €1,999 ($2,300) — right up there with high-end Pixel and Galaxy models.
• The 17 Ultra is getting all the attention as a camera-focused device with best-of-the-best specs, but most buyers are likely considering something closer in price to the standard Xiaomi 17.
• The Xiaomi 17 Ultra's value proposition has weakened compared to the previous generation, though at a discounted price it suddenly becomes excellent value.
• Tech Advisor argues the standard Xiaomi 17 actually comes out ahead for most people — bigger 6,330mAh battery, 35+ hours video playback and faster 100W charging.
