Sony Xperia 1 V vs Vivo X300 Ultra

Sony Xperia 1 V

Sony makes the best camera sensors but Sony's smartphone processing still doesn't fully exploit them — the Xperia 1 V is the closest the company has come, with the new Exmor T sensor and continuous 3.5-5.2× zoom remaining unique selling points, but auto-mode HDR trails iPhone/Pixel processing.

• New 24mm f/1.9 52MP main with Type 1/1.35" Exmor T sensor — 1.7× larger than the Xperia 1 IV's, the headline hardware upgrade.
• 85-125mm telephoto offers continuous optical zoom 3.5×-5.2× — versatility that needs multiple cameras on rivals to match.
• Real-time eye AF + 30fps continuous shooting with autofocus — Sony Alpha DNA carried over from mirrorless cameras.
• Low-light performance still trails Samsung and Google — lights look blown out in completely dark conditions.
• Camera comparison vs iPhone 14 Pro is 'embarrassing' — despite better hardware, processing still trails Apple.
• Photo Pro / Video Pro apps deliver DSLR-style manual controls — best on any phone for users who know what they're doing.

Vivo X300 Ultra

The reason the X300 Ultra exists: a near-1-inch 200MP 35mm main (Sony Lytia 901), a 200MP 85mm periscope, and the best ultrawide sensor on the market, tuned with Zeiss. Reviewers near-universally rate it the best-equipped camera phone of 2026 — with two important caveats: the 35mm default is divisive, and on raw image quality it's only marginally ahead of the cheaper X300 Pro.

• At the center is a 200MP main that's nearly a 1-inch sensor (Sony Lytia 901), backed by a 200MP 85mm-equivalent periscope telephoto — the phone is focused on camera quality and, even more so, video.
• Featuring three extra-large image sensors, the X300 Ultra's uncompromising camera hardware earned a solid rating — but it's hardly better than the cheaper X300 Pro in actual camera performance despite the top-notch hardware.
• I'm not sure I've seen better results from even 1-inch sensors — it's so close to 1-inch and the 35mm focal length makes for more cinematic-looking shots; the 85mm periscope is the sweet spot for portraits.
• It still holds the record for the best portrait-mode photos on a smartphone, especially at 85mm and 135mm; the 14mm ultrawide is sharp edge to edge.

Sony Xperia 1 V

Snapdragon 8 Gen 2 + 12GB RAM delivers flagship-class performance; thermal management improved over the Xperia 1 IV but still throttles under sustained load.

• Snapdragon 8 Gen 2 + 12GB RAM — flagship-tier benchmarks aligned with Galaxy S23 family.
• Thermal management improved vs the IV but still observes 'significant thermal throttling' in prolonged stress tests.
• Real-world performance is better than the synthetic stress tests suggest — display refresh rate never throttled.

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.
• Under sustained camera/imaging load the front reached ~46.8°C and the back ~45.2°C, and around 47°C the refresh rate drops slightly though not all the way to 60Hz.

Sony Xperia 1 V

5,000mAh + Snapdragon 8 Gen 2 efficiency delivers strong real-world endurance — but Sony's 30W wired charging is now firmly behind OnePlus's 80W and Samsung's 45W flagship peers.

• 5,000mAh battery delivers up to 20 hours of continuous 4K playback per Sony's claim.
• Real-world: ~50% remaining after average day of web browsing, messaging, calls, and gaming — strong endurance.
• 30W wired + PD3.0/PPS — 50% in ~30 min. Slow vs OnePlus 11's 80W and S23 Ultra's 45W.
• Wireless + reverse wireless charging supported — feature parity with S23 family for the basics.

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.
• In a head-to-head charge race against the Oppo Find X9 Ultra (80W), the Vivo on 100W finished first at 50 minutes 20 seconds to the Oppo's 52:39.
