Detailed Comparison

Cameras

OnePlus Open

Hasselblad-tuned triple-camera system clearly outshoots the Z Fold 5: 48MP main (LYT-T808 1-inch-class sensor) + 64MP 3x telephoto periscope + 48MP ultrawide. Best foldable cameras of 2023.

Cameras: 48MP main (LYT-T808 1-inch-class, f/1.7, OIS), 64MP 3x telephoto periscope (f/2.6, 70mm), 48MP ultrawide (f/2.2), 32MP cover selfie + 20MP inner.
Hasselblad color tuning delivers more natural shots than Z Fold 5; periscope telephoto reaches 3x optical / 6x quality-preserving.
Best foldable cameras of 2023 — clearly outshoots Z Fold 5 in main + telephoto; on par with Pixel Fold for ultrawide.
Still trails slab flagships (S23 Ultra, iPhone 15 Pro Max) on absolute camera quality — physical sensor limits remain a foldable constraint.

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.

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.

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.
Comparing it directly with the Oppo Find X9 Ultra, even though the Vivo looks great at a glance you could edit the Oppo image and get better detail because the Vivo isn't all over-sharpened and crusty.
Schools the Galaxy S26 Ultra in zoom quality without an excessive camera count — shaping up to be one of the best camera phones not just for 2026 but 2027 and 2028.
The 35mm main is divisive — many feel 24mm is better for phone photography and that 35mm is too tight; cropping to 23–28mm shows a noticeable detail drop.

Battery & Charging

OnePlus Open

4,805mAh dual battery + 67W SuperVOOC wired + 50W wireless — class-leading charging for a foldable. Real-world endurance ~5-6h SOT typical, comparable to Z Fold 5.

4,805mAh dual battery + SD 8 Gen 2 efficiency — comparable endurance to Z Fold 5 (4,400mAh).
67W SuperVOOC wired charging — full in ~42 minutes. Dramatically faster than Z Fold 5's 25W (~1h-1.5h to full).
50W wireless charging — vs Z Fold 5's 15W. The fastest wireless charging in any foldable of 2023.
Real-world SOT ~5-6 hours typical — fully a day for most users, comparable to Z Fold 5.

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.

Value & Verdict

OnePlus Open

$1,699 launch — $100 less than Z Fold 5's $1,799 and meaningfully better hardware. Best book-style foldable of 2023 per The Verge/Engadget; Samsung wins on water resistance and S Pen.

Launched at $1,699 — $100 less than Z Fold 5's $1,799. Aggressive pricing for the best book-style foldable hardware of 2023.
At $900-1200 used in 2026 — the OnePlus Open is the smart book-foldable buy for camera + multitasking buyers, with Galaxy Z Fold 7 ($2K) makes the Open look even better value.
Engadget verdict: 'best book-style foldable of 2023' — thinner, lighter, better cameras and faster charging than Z Fold 5.
vs Samsung Galaxy Z Fold 5 ($1,799): OnePlus wins on cameras, weight/thinness, hinge crease, charging speed; Samsung wins on IPX8, S Pen, longer foldable track record.
vs Pixel Fold ($1,799): OnePlus wins on cameras + multitasking + faster charging; Pixel wins on 7-year update commitment.

Vivo X300 Ultra

This is a deliberately niche, camera-first flagship: roughly €1,175 in China for 512GB, around £1,399 globally for the phone, and close to €2,600 for the full kit. For the people it's aimed at it draws some of the strongest praise of any 2026 phone; for everyone else, a cheaper X300 Pro or the Oppo Find X9 Ultra may make more sense.

Last year's X200 Ultra was, in my opinion, one of the best smartphones of 2025 — and this is the best smartphone I've ever used, with the best camera application I've ever used, provided with zero script from Vivo.
The cameras are nothing short of amazing — this is the best Android camera phone, with image quality better than anything from Samsung.
The versatility here is just ridiculous — more like a phone in a camera than the other way around, a camera system built from the sum of its many parts.
If you accept the 35mm main, are willing to tolerate AI processing in some scenes, and don't mind the front-camera stabilisation limits, this Vivo is an excellent choice.
