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+

The bespoke Snapdragon 8 Gen 2 for Galaxy and 8GB RAM make it indistinguishable from the Ultra for everyday use — much cooler than the Exynos S22+ and still smooth in 2026.

• Snapdragon 8 Gen 2 for Galaxy at 3.36GHz with 8GB RAM and 256GB UFS 4.0 base — same chip as the Ultra, runs the global market without Exynos split.
• No overheating even with sustained gaming and 4K video editing — a clear improvement on the Exynos S22+'s thermal issues.
• Three years in (2026), the chip 'still handles everything' — app opening, multitasking and games like Apex still smooth.
• Light Mode performance profile clocks down the X3 core slightly to preserve power without noticeably impacting performance — free extra battery life.

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+

4,700mAh paired with the efficient chip delivers excellent real-world endurance — owners regularly hit 5-8 hours SOT and full days with 40% to spare. Charging is 45W rated (the standard S23 is only 25W) but caps out at ~1h6m to full and needs the correct PPS cable.

• 4,700mAh battery (up 200mAh from S22+) and 8 Gen 2 for Galaxy give a measured 14h Active Use score and a 111h GSMArena endurance rating — beating the S22+'s 97h.
• Real-world: 5-8 hours of SOT typical, with one owner reporting 12 hours of mixed use (YouTube, gaming, Bluetooth, texting) and still 40% left.
• After 2.5 years, moderate use still gets 2 days of battery — long-term efficiency holds up well.
• 45W wired charging: 21% in 10 min, 39% in 20 min, 55% in 30 min, 79% in 45 min, full in ~1h9m.
• ChargerLAB confirmed: peak charging is ~40W (drops to 33W after 6 min); a PPS-capable charger is needed — without it the rate caps at 27W.

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+

Launched at $999, now $400-500 used / refurbished — strong value for the chip + charging combo, but the standard S23 ($799) and the Ultra ($1,199) overshadow it inside Samsung's own lineup.

• Launched at $999 — middle of the S23 lineup; now ~$400-500 used and increasingly seen at refurbished discounts.
• Phone Arena: 'awkward middle child position, failing to stand out in any meaningful way when compared to its siblings while delivering excellent value of its own at these latest discounts'.
• Matthew Moniz: 'Samsung Galaxy S23 Plus Review - The Best Galaxy S23!' — gets the Ultra's chip and 45W charging at $200 less, without the Ultra's bulk.
• Counter: TechOdyssey would recommend 'zero people' buy the S23+ over a Pixel 7 Pro that's hundreds cheaper with similar cameras.
• vs OnePlus 11 ($699 launch with 80W charging): the S23+ wins on software support and the 3x telephoto; OnePlus wins on charging and price.
