Nothing Phone (4a) Pro

What Reviewers Agree On

The new metal unibody makes the 4a Pro look and feel more premium than Nothing's own £799 Phone 3 — the slimmest, most 'pro'-feeling Nothing yet.
The 6.83-inch 1.5K 144Hz AMOLED is the best display Nothing has ever shipped, with strong real-world outdoor visibility around its realistic 1,600-nit figure.
The dual 50MP main plus 50MP 3.5x periscope-telephoto system is rare flagship-tier camera hardware at $499 and the single biggest reason to buy.
Nothing OS 4.1 on Android 16 is clean, bloat-free and has some of the best design consistency of any Android UI, Google included.
At $499 — the exact price of a Pixel 10a — it's outstanding value, with several reviewers preferring it outright to the 10a.

Detailed Comparison

Cameras

Nothing Phone (4a) Pro

The headline value play: a 50MP Sony LYT-710 main with OIS, a true 50MP 3.5x periscope telephoto (80mm) with OIS, and an 8MP ultrawide — flagship-tier hardware Samsung and Apple don't put in phones at this price. Output is characterful and the telephoto is a genuine win, but reviewers consistently flag inconsistency, average low-light and a gimmicky 140x digital zoom.

Triple rear system: 50MP Sony LYT-710 main (f/1.9, OIS), 8MP ultrawide, and a 50MP periscope telephoto with 3.5x optical zoom (80mm, f/2.9, OIS).
Both the main and periscope-zoom cameras are 50MP and deliver strong results for this price range; the zoom in particular stands out from competitors and even allows for extreme digital zoom.
Having a proper dedicated telephoto shooter is a genuine love, although the camera experience itself is a little bit inconsistent at times.

OnePlus Open

What Reviewers Agree On

Best book-style foldable hardware of 2023 — thinner (5.8mm unfolded), lighter (245g) than Z Fold 5 (253g)
Cover screen aspect ratio (20:9) finally works like a real phone, unlike Z Fold 5's narrow 23.1:9
Inner display crease is meaningfully less visible than the Z Fold 5's — most-praised hinge design of the era
Hasselblad triple cameras (48MP main + 64MP 3x telephoto + 48MP ultrawide) outshoot the Z Fold 5 noticeably
67W wired + 50W wireless charging — dramatically faster than Z Fold 5's 25W wired / no wireless
OxygenOS Open Canvas multitasking — best foldable software outside Samsung One UI

Deal Breakers

IPX4 water resistance only — no dust rating; Z Fold 5 has IPX8 (full water immersion)
Only 4 OS + 5 years of security — short vs Pixel Fold's 7 years
No S Pen support — Samsung Z Fold 5's biggest software advantage
Alert Slider is missing from this OnePlus model (only foldable without it)
$1,699 launch was 'less expensive than Z Fold 5 by $100' but still steep for a first-gen foldable

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.

Battery & Charging

Nothing Phone (4a) Pro

The ~5,080mAh cell reliably gets through a day and endurance improved across all of GSMArena's tests versus the 3a Pro — but it's only an 80mAh bump over last year and looks small next to 6,000–7,000mAh budget rivals. 50W wired charging is the trade-off win; there is no wireless charging at all.

Endurance has improved across the board in all tests compared to last year's Nothing Phone (3a) Pro; with a 68W USB-PD charger the phone peaked at around 42W.
The review unit gets through a day without problems, but it'll certainly be into the red and close to done after about 15 hours of use; the OnePlus 15R has a much meatier battery to last longer.
It's only an 80mAh increase over last year — small fry next to budget rivals like the Poco M8 Pro, which uses silicon-carbon tech to reach 6,500mAh.
50W wired charging is very respectable at this price — besting anything Google, Apple or Samsung offers below £500.
Because the processor isn't power-hungry and the battery is large for the chip, real-world battery life is excellent.
Roughly 13 hours of continuous playback at maximum brightness in a streaming test — impressive for what Nothing is doing at this price.

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.
