Oppo Find X9 Ultra vs Samsung Galaxy A55 5G

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.

Samsung Galaxy A55 5G

A 6.6-inch FHD+ Super AMOLED at 120Hz — vibrant and the highlight of the experience, but caps at ~1,000 nits, below flagship brightness.

• 6.6-inch FHD+ Super AMOLED at 120Hz, the same bright, smooth panel class as the A35.
• The viewing experience is basically what makes this phone 100% worth the money.
• It can't match the S24's 2,600-nit peak, maxing at 1,000 nits in High Brightness Mode.
• The AMOLED gets very dark at night, which photophobic users particularly appreciate.

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).

Samsung Galaxy A55 5G

A 50MP f/1.8 OIS main, 12MP ultrawide and 5MP macro, plus a 32MP selfie. Dependable with strong low-light for the class, weaker against true flagships at night.

• Triple rear: 50MP f/1.8 OIS main (1/1.56"), 12MP ultrawide and a 5MP macro.
• Dependable camera performance with excellent videos, per the GSMArena review.
• Versus the iPhone 13 it holds its own in almost every scenario, and clearly wins in low light with less noise.
• Night mode isn't on par with the iPhone 15 or Pixel 8 Pro, but it's a clear improvement and competitive at the price.
• Video records up to 4K 30fps on the main, ultrawide and front cameras, with smoother FHD 60fps available.

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.

Samsung Galaxy A55 5G

Exynos 1480 with up to 8/12GB RAM — solidly midrange. Smooth for daily use thanks to 120Hz, but with occasional micro-stutter under load.

• The A55 ups the ante with more memory (8GB), a faster Exynos 1480 and a superior camera setup over its predecessor.
• There's occasional lag or micro-stutter when launching the camera in social apps or switching between apps.
• 120Hz is well optimised and the UI stays smooth, with the camera even opening slightly faster than on the A56.
• It runs cooler than a Galaxy S24 in sustained tests (A55 ~31–34°C vs S24 ~37–38°C) and beat the A35 on AnTuTu.
• An owner found it ran cooler/better than an S23 FE, which heats up faster even just browsing social media.

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.

Samsung Galaxy A55 5G

A 5,000mAh battery with very strong endurance, undercut by slow 25W wired charging and no wireless charging.

• The 5,000mAh battery can stretch toward two days if you're sensible with gaming and camera use.
• It uses only ~2% battery over 8 hours of 5G standby — far better than a Galaxy S24's ~5%.
• Around 8 hours of screen-on-time means it easily lasts a full day; the battery 'just goes on and on.'
• It does not support wireless charging at all; charging is 25W wired over USB-C only.
• The lack of fast charging is the one thing owners really miss in a rush versus 90W rivals.

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.

Samsung Galaxy A55 5G

A 'boring but solid' midranger that becomes an excellent value at its frequent discounts — though it's not officially sold in the US.

• A boring update, but still a solid mid-ranger for its price.
• It once again seems to be one of the best mid-tier Android devices of the year for the rest of the world.
• It packs a lot of premium features into a midrange smartphone.
• It's half the price of its flagship counterpart, but the gap between the two isn't nearly as large as you'd expect.
• It has dropped to as low as £249 in price-cut deals — exceptional value at that level.
