ASUS Zenfone 12 Ultra vs Oppo Find X9 Ultra

ASUS Zenfone 12 Ultra

A big, bright 6.78-inch 144Hz AMOLED that's very good in practice — but it's FHD+, not the QHD some expect from an 'Ultra'.

• It's a 6.78-inch LTPO AMOLED at 144Hz, HDR10, with 1,600 nits HBM / 2,500 nits peak at 1080x2400 (20:9), with an always-on display — unchanged from the 11 Ultra.
• Peak brightness hits 2,500 nits with a real-hero ~2,200 nits at 20% APL — though minimum brightness is a bit high at almost 6 nits.
• It's an LTPO 1–120Hz panel with a boosted 144Hz refresh mode available during gaming.
• Calling it an 'Ultra' but shipping no QHD screen is a recurring criticism among buyers.

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.

ASUS Zenfone 12 Ultra

The gimbal-stabilized main camera is the genuine highlight; the rest of the system is solid-for-the-price but clearly trails rival flagships.

• Asus swapped the main camera sensor as part of a gimbal-stabilizer upgrade that now provides up to 66% better stabilization (6-axis, up to 5° each direction).
• The lead shooter promises gimbal-level stability when snapping or filming — the standout reason to consider this phone.
• The main camera captures 12.5MP pixel-binned stills; the ultrawide is limited to 4K30, the telephoto to 1080p60 and the selfie to 1080p30.
• Camera quality is subpar versus other flagships, with no autofocus on the wide-angle and the front camera capped at 1080p 30fps video.
• Photography and processing fall away once you push past 3x optical, where rivals with longer reach stay stronger.
• Asus confirmed the Zenfone 12 Ultra would launch with new AI camera features.

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.

ASUS Zenfone 12 Ultra

Snapdragon 8 Elite plus ROG-derived cooling makes this a fast, stable performer with no thermal drama.

• The Snapdragon 8 Elite provides excellent burst performance.
• Paired with up to 16GB RAM and UFS 4.0, load times are fast, app switching is seamless and gaming performance is rock solid.
• The most demanding titles held a steady frame rate with no lag and no overheating, impressive given the slim 8.9mm body.
• It carries thermal controls (limit CPU boost, dim brightness, disable 5G when hot) so you can tune sustained performance outdoors.
• Its gaming result was slightly better than the 11 Ultra despite the overall battery regression.

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.

ASUS Zenfone 12 Ultra

Strong real-world endurance from the 5,500mAh cell with fast 65W charging — though lab testing shows a regression versus the 11 Ultra.

• The 5,500mAh battery delivered an easy 10–11 hours of screen-on time across a mix of socials, YouTube and light gaming.
• 65W wired charging takes it 0–100% in roughly 39–45 minutes, with 15W wireless and 10W reverse wired charging.
• GSMArena's testing showed a regression — the 11 Ultra hit ~17h14m of battery life versus ~14h11m for the 12 Ultra.
• It carries an IP68 rating and a large 5,500mAh cell — strong stamina credentials for the class.
• One tester reported no wireless charging on their unit, though most sources confirm 15W wireless is supported.

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.

ASUS Zenfone 12 Ultra

It undercuts the big flagships on price and is excellent value used — but a thin software commitment and a so-so camera mean stronger options exist if those matter most.

• Although it's an Ultra with Ultra features, the price is significantly lower than a Samsung Galaxy S-series Ultra.
• It's expected to deliver Qualcomm's latest chipset, a large display and a price tag that undercuts a lot of the competition.
• New, the 16GB/512GB model sits around $1,039–$1,099 via import (not officially sold in the US); used units in mint condition go for $750–$850.
• If you're buying new at $1,000+ and cameras or long-term software support matter most, there are stronger options out there right now.
• The Zenfone line has been called an unremarkable big-screen smartphone that does nothing wrong but is eclipsed by stronger competition.

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.
