Oppo Find X9 Ultra vs Samsung Galaxy S23

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 S23

Same bespoke Snapdragon 8 Gen 2 for Galaxy (3.36GHz) chip as the Plus and Ultra — no compromise. 40% faster than the S22 Ultra and meaningfully cooler. 8GB RAM keeps multitasking smooth even 3 years on.

• Snapdragon 8 Gen 2 for Galaxy at 3.36GHz with 8GB RAM and 128GB UFS 3.1 base — same chip as the Plus and Ultra, no Exynos split.
• Bespoke 8 Gen 2 for Galaxy is up to 40% faster than the S22 Ultra and adds Ray Tracing support for certain games.
• Cool under normal use — even at 38-39°C ambient temps, no overheating issues; long-term performance holds up.
• Three years in (2026): app opening, multitasking and Call of Duty still smooth — chip plus 8GB RAM has aged well.
• Ars Technica caught a 60GB Samsung Android system partition out of the box — 4x the size of a Pixel 7 Pro's 15GB, and only one OS copy means ~30 min downtime during updates.

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 S23

3,900mAh — the family's weakest point. Real-world ~5-6 hours of SOT typical (worsened by One UI 6/7), and only 25W charging means ~1h12m to full. The compact form factor's main cost.

• 3,900mAh battery — only 200mAh more than the S22, no 4,500mAh+ like the Plus. The smallest cell in the family.
• Real-world: ~5-6 hours of SOT typical, comfortably a full day of moderate use, 1-1.5 days possible.
• Battery life noticeably dropped after One UI 6 update — owner went from 5-6h SOT on 5G to barely 2h, recommends staying on Android 13 for best results.
• Feb 2026 update real-world: ~4h SOT on Wi-Fi, drops to <2h on 5G — battery efficiency has gotten worse with time.
• Charging caps at 25W (the Plus and Ultra get 45W): 0-100% takes ~1h12m on Samsung's 25W charger.

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 S23

$799 launch with the same chip as the $1,199 Ultra — strong value despite the 25W charging and smaller battery. Now $300-400 used, often the best compact-flagship option versus Pixel 7/8 and OnePlus 11.

• Launched at $799 with the same Snapdragon 8 Gen 2 for Galaxy chip as the $1,199 Ultra — outstanding flagship value at the base tier.
• Engadget verdict: 'A solid phone that's probably not worth the upgrade' from a recent S22 or S21 — Samsung's iterative cadence.
• Notebookcheck calls it 'the small S23 that makes the biggest leap' — the S23 family's largest year-over-year improvement is on the standard tier.
• Best compact Android flagship at ₹45k in 2024 — still recommended for buyers who want a one-handed phone with good cameras.
• vs Pixel 7 — Pixel wins on haptics, one-handed design and software smarts; S23 wins on chip speed, battery life and update commitment.
