Oppo Find N5

What Reviewers Agree On

World's thinnest book-style foldable — 4.21mm unfolded, 8.93mm folded, 229g — that feels like a normal phone when shut, confirmed by 9to5Google, MKBHD, JerryRigEverything and Digital Trends.
Class-leading battery life for a foldable: the 5,600mAh silicon-carbon cell outlasts the Pixel 9 Pro Fold, Magic V3 and Galaxy Z Fold6 by ~30% in Notebookcheck and Bhw4cpLAGO8's 11–12h screen-on-time over six months.
The near-creaseless inner display with anti-reflective coating is the best foldable screen implementation reviewers have used (9to5Google, ZONEofTECH, gadgetmatch).
ColorOS multitasking (Boundless View / Open Canvas) and Mac integration via O+ Connect are standout software wins — the only such Mac link on Android outside China (The Verge, 9to5Google).
It is the best-rounded, most refined book-style foldable on the market — Android Central, Pocket-lint, 9to5Google and gadgetmatch all rank it #1 in the category.

Detailed Comparison

Cameras

Oppo Find N5

A genuine periscope tele on a sub-9mm foldable is impressive, but the 8MP ultrawide and low-light performance keep it a notch below slab flagships.

Oppo fit a periscope-style telephoto into the slim body and all cameras (except ultrawide and selfie) shoot up to 4K 60fps — a strong foldable camera kit.
The ultrawide is the clear weak point: an 8MP sensor that is disappointing next to the high-resolution main and telephoto lenses.
Historically foldables have worse cameras than flagship slabs, and the Find N5 is no exception — though it's still one of the best camera setups on a foldable.
In a head-to-head, the Find N5 has the better overall main/wide camera experience that's closer to a regular phone, though the Galaxy edges it in low light.

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

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.
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.

Performance

Oppo Find N5

A seven-core Snapdragon 8 Elite paired with 16GB RAM keeps it fast and cool — a deliberate efficiency-over-peak trade reviewers mostly endorse.

Runs a Snapdragon 8 Elite with 16GB LPDDR5X RAM (up to +12GB expansion) and 512GB storage as standard, with Wi-Fi 7 — no lag or slowdowns reported across months of use.
Owners importing from the OnePlus Open found the 7-core (vs 8-core) chip is only a ~5% performance difference but saves a lot on heat and battery.
Connectivity is excellent for a foldable — IR blaster, Wi-Fi 7 and DisplayPort video output over USB-C.
The thin chassis raised overheating concerns, but a year on, owners report the Snapdragon 8 Elite stays manageable even in the slim profile.

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.

Battery & Charging

Oppo Find N5

The 5,600mAh silicon-carbon cell is the Find N5's quiet superpower — it outlasts every contemporary foldable and charges at 80W wired / 50W wireless.

Notebookcheck measured it lasting over 30% longer than its predecessor, the Pixel 9 Pro Fold, Magic V3 and Galaxy Z Fold6 in early battery tests.
Six months in, the 5,600mAh silicon-carbon battery with Snapdragon 8 Elite consistently delivers 11–12 hours screen-on-time, up to 15–16 hours on content, ~10 hours when gaming.
80W SuperVOOC wired charges 0–100% in under 50 minutes, plus 50W AirVOOC wireless and reverse charging for other devices.
In a same-chipset endurance drain vs Honor Magic V5 and Galaxy Z Fold 7, the Find N5 finished second at 7h26m of mixed-app load, narrowly behind the Magic V5's 7h31m and well ahead of the Fold 7.
Camera-intensive days are the exception — heavy shooting burned ~71% of the battery for under 4 hours of screen-on-time, normal usage is far better.

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.
