Detailed Comparison

Display

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.

Deal Breakers

Cameras are very good but still a half-tier behind Pixel, Galaxy, and iPhone — particularly in low light, where Night Mode loses sharpness and the Hasselblad processing can overbrighten shadows.
Software support is only four OS upgrades and six years of security patches — short of Samsung and Google's seven-year commitments.
Qi2 wireless charging requires the OnePlus magnetic case because the phone itself has no built-in magnets, frustrating buyers expecting MagSafe out of the box.
No carrier support in the US — you have to buy it unlocked from OnePlus, Best Buy, or Amazon, which kills the monthly-installment buying habit most American buyers rely on.
Reddit users on r/gadgets flag that a $900 phone marketed on 'less AI' is no longer the flagship-killer value proposition OnePlus built its name on.

Vivo X300 Ultra

What Reviewers Agree On

The camera system — twin ~1-inch 200MP main and 200MP 85mm periscope plus a large ultrawide — is the best-equipped on any 2026 phone and the entire reason the device exists.
Video is class-leading: 4K 120fps 10-bit Log with Dolby Vision recorded on-device (no SSD), 8K30 across the rear cameras, and 4K 60fps on every lens including the selfie.
Battery life is genuinely strong — roughly 16 hours active-use score, ~7h heavy screen-on time, and 13–14 hour days with charge to spare, on the 6,600mAh cell.
The Zeiss 200mm/400mm telephoto extenders deliver real, usable optical reach (8.7x and 17.4x) with surprisingly good handheld stabilisation.
100W wired charging refills the big battery in roughly 46–50 minutes, with 40W wireless on top.
The 6.82-inch 144Hz LTPO AMOLED is among the best displays available, hitting ~1,900 nits in auto and ~3,300 nits peak.

Deal Breakers

The 35mm (~1.5x) default main focal length is polarising — many reviewers find it too tight/zoomed versus the usual 24mm.
It heats up quickly under sustained camera or gaming load and throttles to roughly 60–65% stability in prolonged stress tests.
The full experience needs the expensive Photography Kit — the global bundle approaches €2,600 and the 200mm lens isn't in every box.
Notebookcheck found it 'hardly better than the X300 Pro in camera performance despite top-notch hardware', and Linus preferred Oppo's less over-sharpened processing.
It launched in China first with a rocky early software state (fixed via updates), and global availability/pricing is limited and steep.

Vivo X300 Ultra

A 6.82-inch 144Hz LTPO AMOLED, now flat rather than quad-curved. Lab measurements put real brightness near 1,900 nits in auto and ~3,300 nits on a small window — among the best panels on any phone — and reviewers single out content consumption and clarity as standouts.

We measured a maximum of over 1,900 nits in auto-brightness mode and over 3,300 nits when lighting up a smaller portion of the screen.
Consuming content, scrolling the web, pixel-peeping and zooming in on text — it doesn't get any clearer, or with the 144Hz any smoother, than the display on the X300 Ultra.
It delivers an excellent max brightness of around 1,935 nits with a 75% white pattern and a peak of 3,328 nits with a 10% pattern.
Vivo has gone with a flat display this time, a clear shift from the quad-curved style of the X200 Ultra.
It's a 6.82-inch AMOLED with a claimed 4,500-nit HDR peak that can reach that figure in a one-person window watching HDR content; PWM sits around 3.5% at max brightness, better for flicker-sensitive users.
An absolutely stunning display with terrific, bass-heavy stereo speakers to match.

Performance

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.

Vivo X300 Ultra

Snapdragon 8 Elite Gen 5 plus Vivo's custom imaging silicon delivers flagship benchmark numbers and strong gaming, but the camera-heavy hardware runs hot — sustained stress tests show roughly 60–65% stability and the camera app warms it up fast.

At the heart is Qualcomm's current flagship Snapdragon 8 Elite Gen 5, supplemented by Vivo's custom VS1 and V3-Plus imaging chips.
It boots in 16 seconds (vs 21s for the S26 Ultra and 19s for the iPhone 17 Pro Max) and posts an AnTuTu score over 3,800,000, stronger than Samsung.
In a prolonged stress test it throttled CPU performance to about 60% of peak — in line with other high-powered flagships — and 3DMark stability landed around 63–66%.
It gets a bit hot after 30–40 minutes of gaming, but with no throttling even past an hour and never uncomfortable to hold; boost mode at max graphics gives around 4 hours of Wuthering Waves on a full charge.
Native 120fps gaming with smooth/very-high graphics in many titles, with temperature barely crossing 35°C and power draw around 4W in battle-royale modes.

Battery & Charging

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.

Vivo X300 Ultra

Vivo grew the silicon-carbon cell 10% to 6,600mAh while keeping the body the same size. Real-world endurance is strong — ~16h active-use score, ~7h heavy screen-on, 13–14 hour days with charge to spare — and 100W wired refills it in under an hour, with 40W wireless.

Vivo increased the battery by 10% to 6,600mAh despite the phone being practically the same size on paper.
In our battery test it earned an active-use score of almost 16 hours; 100W charging took it 0–66% in 30 minutes and a full charge in 46 minutes, plus 40W wireless. A charger is in the box except in Europe.
On the China version I'm finishing entire 13–14 hour days with 25–30% left; the global version keeps the 6,600mAh cell so battery life should comfortably last 12–13 hours of heavy use.
Getting nearly 7 hours of screen-on time with very heavy usage from the 6,600mAh silicon-carbon unit, with 100W wired and 40W wireless charging support.
After a 4-hour heavy-usage simulation the phone still had ~45% battery left, which is solid by today's standards, and 100W wired charging takes about 45 minutes to full.
