OnePlus 11 vs Oppo Find X9 Ultra

OnePlus 11

Snapdragon 8 Gen 2 + up to 16GB RAM + UFS 4.0 — flagship-grade performance matching the S23 family. OxygenOS 13 on Android 13 (now more 'ColorOS-like' after Oppo merger).

• Snapdragon 8 Gen 2 + 8/16GB RAM + 128/256GB UFS 4.0 — flagship performance, matches Galaxy S23 family on benchmarks.
• OxygenOS 13 on Android 13 — increasingly 'ColorOS-like' since Oppo merger, divisive among long-time OnePlus fans.
• 4 OS updates + 5 years of security — short vs Pixel 8's 7 years; ages through Android 17 / security 2028.
• Cooler sustained performance than S23 Ultra — OnePlus's vapor chamber + 8 Gen 2 throttling tune is best-in-class for gaming.

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.

OnePlus 11

5,000mAh battery + class-leading 80W SuperVOOC charging — full in ~25 minutes, dramatically faster than any 2023 rival. The trade-off: NO wireless charging, a regression from the OnePlus 10 Pro's 50W wireless.

• 5,000mAh battery + 8 Gen 2 efficiency delivers reliable all-day endurance — ~6-7 hours of SOT typical.
• 80W SuperVOOC wired charging — full in ~25 minutes (0-50% in ~10 min), dramatically faster than the S23+/Ultra's 45W (~1h) or iPhone 15 Pro Max's 20W (~1h45m).
• NO wireless charging — major regression from the OnePlus 10 Pro that had 50W wireless. Biggest deal-breaker for many reviewers.
• Multi-phone drain test: OnePlus 11 placed 4th of 7 at 9h46m total runtime — beaten by iPhone 15 Pro Max, Vivo X100 Pro and just edged by S24 Ultra.

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.
