OnePlus 13 vs Oppo Find X9 Ultra

OnePlus 13

Every reviewer calls this one of the best smartphone screens of 2025: a 6.82-inch LTPO AMOLED that peaks at 4,500 nits, supports Dolby Vision and HDR10+, and earned DisplayMate's first-ever A++ rating. The new ultrasonic fingerprint reader is faster and stays reliable when wet, and PWM dimming runs at 2,160 Hz for eye-sensitive users. The only ongoing nitpick is the gently curved glass edges.

• The 6.8-inch OLED panel hits a peak of up to 4,500 nits — even brighter than Samsung's Galaxy S25 Ultra at 2,600 nits.
• 1,600 nits in high brightness mode and 4,500 nits peak brightness make this the world's first display to earn DisplayMate's A++ rating.
• 120Hz OLED displays are sharp, colorful, and smooth, though the default lower resolution save-battery setting kept lowering brightness a little too much in testing.
• The display is in the upper echelon of smartphone screens — beautifully tuned, incredibly bright, smooth, and easier to use without aggressive curves.
• The new ultrasonic fingerprint reader plus Aqua Touch 2.0 keeps the screen responsive even when wet — old optical readers struggled with that.
• At 510 PPI the display is incredibly sharp and content absolutely pops, with a glove mode for thin gloves up to 0.5cm thick.
• Trusted Reviews calls this 'the best (and only) flagship in the US for PWM-sensitive folks' thanks to 2,160 Hz high-frequency PWM dimming.

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.

OnePlus 13

The OnePlus 13 was the first non-gaming flagship globally to ship with the Snapdragon 8 Elite, and reviewers report a generational jump in both CPU and GPU. Multi-core Geekbench scores rival the Galaxy S25 Ultra and beat the iPhone 16 Pro on GPU benchmarks. Thermal management is exceptional — Dave2D ran Genshin Impact at max settings indefinitely without throttling — and 12-16GB of RAM keeps multitasking buttery smooth.

• The Snapdragon 8 Elite delivers a 31% higher CPU clock speed, 36% higher AnTuTu, 44% higher single-core Geekbench and 14% higher 3DMark over last year's best — Wilt Chamberlain numbers.
• Both the OnePlus 13 and ROG Phone 9 Pro ran Genshin Impact at max graphics indefinitely at 60fps without throttling — never seen before on stock devices.
• Geekbench 6 multi-core hits 9,267 on the OnePlus 13 — only about 5% behind the Galaxy S25 Ultra at 9,828, with 16GB RAM versus Samsung's 12GB.
• Snapdragon 8 Elite single-core CPU performance is practically spitting distance from the A18 Pro while it actually surpasses the iPhone 16 Pro in multi-core and 3DMark Wild Life Extreme.
• Even when heavily used, the phone doesn't get unreasonably hot, doesn't stutter or lag, and doesn't unreasonably suck up battery life.
• The Snapdragon 8 Elite overtaxes the cooling system of normal smartphones under high sustained load — pronounced throttling was the OnePlus 13's main weakness in lab testing.
• Image processing is basically instant — edit a video and render out and it's done in seconds, with no signs of slowdown after seven months.

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 13

The OnePlus 13's signature feature: a 6,000 mAh silicon-carbon battery (vs the 5,000 mAh ceiling rivals are stuck at) that delivers genuine two-day endurance, paired with 100W wired SuperVOOC and 50W AirVOOC wireless charging that refills the phone in 36 minutes. Engadget's video rundown clocked 30h 18m — almost an hour longer than the S25 Ultra. The catch: top wireless speeds require OnePlus's proprietary magnetic puck.

• With average use the phone easily lasts two full days; with heavy use you can go from morning to night without a top-up, thanks to OnePlus's Silicon NanoStack battery tech.
• 30 hours 18 minutes on Engadget's local video rundown — nearly an hour longer than the Galaxy S25 Ultra (29:27) and almost three hours better than a Pixel 9 (27:32).
• Two full days of WhatsApp, Discord, Chrome, Instagram and Android Auto without worrying about where the charger is — silicon-carbon is a real generational leap.
• Even with high brightness, multitasking, GPS navigation and Bluetooth streaming, the OnePlus 13 ends the day with six hours of screen-on time and 35% battery left.
• 80W wired charging refills the phone from zero to 100 in 36 minutes, with 50W wireless charging via the AIRVOOC puck — the OP13 recharges twice as fast as a Galaxy S25 with cable and three times faster wirelessly.
• The Snapdragon 8 Elite drives a 25-30% (conservatively) jump in battery life over Snapdragon 8 Gen 3 — possibly closer to 40% on like-for-like workloads.
• Hitting maximum wireless charging speeds requires the proprietary 50W AIRVOOC puck — universal Qi chargers throttle dramatically.
• Reddit r/Android: 'I'm jealous of that battery life' — the most-upvoted user reaction in the OnePlus 13 megathread.

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.

OnePlus 13

OxygenOS 15 on Android 15 has matured into a fast, customizable Android skin with deliberately restrained AI — Gemini and Circle to Search are present, plus a Notes assistant and AI Reflection Eraser, but OnePlus has explicitly chosen not to chase Galaxy AI. The Live Alerts feature mimics Apple's Dynamic Island, with limited third-party support. The catch: four OS upgrades and six years of security patches still trails Samsung and Google's seven.

• OnePlus is keeping AI refreshingly low-key — Google Gemini and Circle to Search plus a smarter Notes app, but AI is nothing like the big focus it is on the Galaxy S25 family.
• OxygenOS 15 is very, very good — animation speed improvements and extra attention to detail make this version of Android 15 feel uniquely tunable.
• OxygenOS 15 has taken back control after years of ColorOS-style bloat creep — 'I'm not simply tolerating it, I like it.'
• Software support is bumped to four Android OS upgrades and six years of security updates — better than before, but still not as long as Samsung and Google's seven years.
• AI Reflection Eraser did a respectable job removing window glare on a hotel photo, but most AI features only work with an internet connection.
• The Live Alert capsule around the selfie camera is a Dynamic Island clone — 'if you're going to copy stuff, copy the good stuff' — though third-party support is limited.
• The Dynamic Island rip-off shipped with OxygenOS 15 feels like a solution to a non-existent problem in Android — widgets already do this job better.
• Reddit users on r/gadgets cheer the lack of AI focus: 'I can't wait for a few years from now when a phone company starts advertising that being AI-free is a feature.'

Oppo Find X9 Ultra

ColorOS 16 has matured a lot and is fast and smooth, but it still trails Samsung and Google on AI depth and feels iOS-derived to some — the phone's clearest weak point relative to its hardware.

• ColorOS 16 feels like one of the best versions yet.
• It's a good Android experience but not on par with the Galaxy experience for AI features and tool integration, and portrait autofocus struggles in some low-light conditions.
• For me it's the best version of Android I've ever used — light, fast and smooth with no major issues.
• The hardware is superior to the latest Samsung, but the software feels like an imitation of iOS.
• With a bit of tweaking and updates, Oppo's software and camera engineers can make this even better — there's clear headroom.

OnePlus 13

At $899 starting (often discounted to $799 via OnePlus's perpetual trade-in deals), the OnePlus 13 is consistently called the best Android value of 2025. The S25 Ultra costs $400 more, the S25+ $100 more, the iPhone 16 Pro $100 more — and the OnePlus matches or beats all three on battery, brightness and charging while landing a half-tier behind on cameras and falling short on update commitment. Reddit sentiment is more mixed: a vocal r/gadgets minority argues a $900 phone isn't a 'flagship killer' anymore.

• For $899 you get longer battery life, a brighter screen, more RAM, greater storage and the same 3x zoom as a base Galaxy S25+ — all for $100 less. That's just a good deal.
• The 12GB/256GB OnePlus 13 costs $400 less than the cheapest Galaxy S25 Ultra — the difference between getting a new phone or getting a new phone and a smartwatch.
• This is the best OnePlus phone to date, and at $899, arguably the best Android phone period.
• The OnePlus 13 cameras, display and battery life all compete handily against the iPhone 16 Pro Max and Galaxy S24 Ultra — but the phone is priced like an iPhone 16 or Galaxy S24.
• It's nice to see OnePlus continuing to stick to its roots by offering everything you need at a slightly lower price than Samsung, Google and Apple flagships.
• OnePlus offers a perpetual $100 discount on the upgraded model plus a guaranteed $100 trade-in — effectively making the OnePlus 13 a $799 flagship.
• OnePlus is positioned under competitors like the Pixel 9 Pro, Galaxy S25 Ultra and iPhone 16 Pro — far from the bargain pricing that defined OnePlus in the early days, but still strong value.
• Reddit r/gadgets pushes back: 'I don't enjoy this being made the new normal and being framed as reasonable!' — $900 is the price of a higher-end phone with a focus on AI, so why no price cut for dropping it?
• Reddit r/Android: 'Any excuse to get this over the Realme GT7 Pro which is 300 Euros less? Same chipset, same display, bigger battery and same manufacturer (BBK Electronics).'

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.
