Nothing Phone (4a) vs OnePlus 15

Nothing Phone (4a)

A genuine highlight for the price — a big 6.78-inch 120Hz AMOLED that's bright, sharp and HDR-capable, beating similarly priced rivals.

• 6.78-inch AMOLED, 120Hz, 2160Hz PWM, HDR10+, 800 nits typical / 1,600 nits HBM / 4,500 nits peak at 1224x2720 (440ppi).
• The 6.78-inch display is 23% brighter than the 3a, reaching 1,600 nits outdoors with a 4,500-nit HDR peak.
• Brightness goes up to 4,500 nits peak, remaining easily readable outdoors — the display is very strong for this price range and one of the standout features.
• In the real world it hits around 700 nits peak SDR and ~1,550–1,600 nits in HDR, with 460ppi and dynamic 120Hz.

OnePlus 15

A 6.78-inch flat LTPO AMOLED that drops the OnePlus 13's QHD+ for a 1.5K (FHD+) panel but adds a 165Hz refresh rate and a dedicated touch-response chip. Lab-measured brightness (~1,200–1,950 nits depending on test) trails the iPhone, but reviewers find it bright, smooth and a standout for gaming.

• The OnePlus 15 has a slightly smaller 6.78-inch display with a lower 1272×2772 resolution, down to FHD+ from QHD+, but it hit 1,940 nits at 10% fill and 2,187 nits at 75% fill, and confirmed 165fps gaming.
• OnePlus claims 1,800 nits HBM; lab testing reached 1,951 nits in a 1% window, and the display refreshes up to 165Hz in gaming mode.
• Wired charging is now 120W and the screen reaches 1,800 nits full-screen; the bezels are even thinner at just 1.15mm and the LTPO panel genuinely drops to 1Hz.
• Independent testing measured peak brightness of 1,222 nits — an improvement over the OnePlus 13's ~1,140 nits but still trailing the iPhone 17 Pro Max by a wide margin.
• For gaming it stands out like no other phone — incredibly bright and colourful with the 165Hz refresh.
• It uses a dedicated display/touch-response chip that samples touch inputs at 3,200Hz, and the touch experience is noticeably better than the iPhone 17's.

Nothing Phone (4a)

A standout 3.5x periscope telephoto at this price and a solid main camera, undercut by an under-optimised zoom and a basic ultrawide.

• A triple setup — 50MP main, a 50MP periscope telephoto and an 8MP ultrawide — undoubtedly one of the best experiences at this level.
• The telephoto has been tweaked to a much better 3.5x (80mm) zoom factor.
• A telephoto with optical zoom at this price is great, but this is the worst optimisation I've seen on a 3.5x camera — expect disappointment if you buy for the zoom.
• The 3.5x optical-zoom telephoto is one of the biggest highlights, adding much more flexibility than most competitors in this price range, and the cameras are surprisingly capable.
• Each camera here feels better than what you'd get on Samsung at the price, and the main is solid with nice detail.

OnePlus 15

The most divisive part of the phone. OnePlus ended its 5-year Hasselblad partnership and moved to smaller in-house-tuned 'DetailMax' sensors: a triple 50MP wide + ultrawide + 3.5x telephoto. Some reviewers rate the results among the best camera phones; many call it a regression from the OnePlus 13 with color-accuracy and high-zoom issues.

• OnePlus's 5-year Hasselblad partnership has ended and the rear sensors are smaller than the OnePlus 13's — every rear camera sensor is smaller, which doesn't bring joy.
• The camera is consistently inconsistent — a recurring theme across reviews of this phone's imaging.
• The photos were usually just as good as the best camera phones, and in some cases the OnePlus 15 shots were the best compared to the Pixel 10 Pro and Galaxy S25 Ultra — and it's the best camera phone tested for fast-moving subjects.
• It has three 50MP rear cameras (wide, ultrawide, 3.5x optical telephoto); both it and the iPhone 17 Pro are impressive zoom shooters, but the iPhone is the obvious selfie winner.
• Zoom looks great up to 30x in good daylight, but beyond 20x it leans heavily on AI — human faces look drawn-on or flat, though buildings and signboards hold up well; 8K30 video doesn't feel sharp.

Nothing Phone (4a)

A capable mid-range chip that handles everyday use and casual gaming well — not a powerhouse, but appropriate for the price.

• Gaming is absolutely possible on this device, with solid everyday performance for the class.
• There's no shortage of substantial hardware upgrades over the 3a, even if the design doesn't stand out as much as the Pro.
• After 24 hours the home screen is extremely customisable and feels massively more functional than iOS, with no responsiveness complaints.
• Gesture-based navigation is fully supported and the overall experience is good thanks to Nothing's optimisations.

OnePlus 15

Snapdragon 8 Elite Gen 5 with up to 24GB RAM and a custom tri-chip setup — it tops benchmark charts, beats the iPhone's A19 in multi-core and runs games at up to 165fps. The asterisk is sustained thermals: day-to-day it stays cool, but extended stress benchmarks repeatedly overheat and shut down.

• Across a benchmark suite the OnePlus 15 performed 19–22% better than the OnePlus 13 and 14–19% better than the S25 Edge, and outperformed the OnePlus 13 by 10% in the stress test.
• Geekbench shows the Snapdragon 8 Elite Gen 5 easily beating the A19 with a multi-core score over 11,000; in Genshin Impact it averaged 119fps vs the iPhone 17's 107fps over 30 minutes, running cooler at under 36°C.
• BGMI runs native 120fps (165fps with frame interpolation) at under 35°C and under 4W power draw, making it one of the best phones for gaming with its 165Hz panel and bypass charging.
• In a 15-minute 20-thread CPU throttle test it throttled to 82% of max performance at a controlled 34–35°C with only 3% battery drain.
• It flashed an overheating warning after barely 8 minutes of a peak-load benchmark, shutting it down and disabling the flashlight and hotspot — though in day-to-day use it runs smoothly with only moderate warmth.
• In Wuthering Waves it held 60fps until ~46°C then capped to 45fps and recovered after ~3 minutes, averaging 57fps and 7W — heavy sustained 3D load is where the thermal limits show.

Nothing Phone (4a)

A ~5,080mAh cell with 50W wired charging — reviewers call endurance strong, but a notable group of owners report disappointing screen-on time.

• The Nothing Phone (4a) features a ~5,080mAh cell which delivers very strong endurance in everyday use.
• The battery grew slightly — about 80mAh in most markets but a more meaningful 400mAh in India — with a 50W PD unit recommended on the box.
• Several owners report only 4–6.5 hours of screen-on time with moderate use — worse than other phones with similar ~5,000mAh batteries.
• Battery life on this phone is excellent in everyday use.

OnePlus 15

The single biggest reason to buy this phone. A 7,300mAh silicon-carbon cell delivers the best smartphone battery life ever measured — a record ~25-hour drain test and 2–2.5 days of real use — with 120W wired charging refilling it in ~40–51 minutes plus 50W wireless.

• The OnePlus 15 lasted an insane 25 hours 13 minutes in the drain test — officially the best phone for battery life, beating the iPhone 17 Pro Max's 17h54m and lasting over 10 hours longer than the Galaxy S25 Ultra.
• The OnePlus 15 just delivered the best battery life we've ever measured — a very, very good phone and a strong value pick for late 2025.
• In real use it averaged 2 days 11 hours on a full charge, and 7–8 hours of screen-on time is effortless thanks to the 7,300mAh cell and aggressive standby management.
• 120W SuperVOOC charged 1→50% in 22 minutes, 75% in 36 minutes and a full 1→100% in 51 minutes; other tests hit a full charge in roughly 40–43 minutes.
• It also keeps 50W AirVOOC wireless charging — about 30% in 30 minutes and ~85% in 92 minutes, with the device staying cool around 34–35°C.
• The battery is so large you could cap charging at 85% to preserve long-term health and still have more capacity than a Galaxy S25 Ultra at 100%.

Nothing Phone (4a)

Near-stock Nothing OS is repeatedly singled out as one of the best, cleanest and most customisable Android experiences at any price.

• The UI is pretty much stock Android, which is the best Android experience — Nothing and Pixel offer the best Android experience.
• While hard to compare to Samsung's far more customisable One UI, Nothing's OS is one of the best ways to experience Android.
• The in-house gallery, voice recorder and weather apps have wonderful design consistency, with everything else left as Google's clean defaults.
• The home screen is extremely customisable with built-in and user-made widgets — fresher, clearer and bolder than iOS.

OnePlus 15

OxygenOS 16 on Android 16 — clean and fast, and a clear AI redemption after the OnePlus 13: Plus Mind (via the new plus key), AI Eraser, plus Google's Gemini Live and Circle to Search. The reservation is the 4-year OS / 6-year security commitment and the lingering uncertainty over OnePlus's regional operations.

• OnePlus redeems the OnePlus 13's lack of AI with OxygenOS 16 — AI Eraser, the Pixel-Screenshots-like Plus Mind via the dedicated plus key, plus Gemini Live and Circle to Search.
• Under all the AI trends OxygenOS still feels like OxygenOS — clean, light and more customisable than a Pixel, with one of the best dark-icon implementations in the segment.
• OnePlus commits to 4 years of major Android updates and 6 years of security patches — not elite, but solid for a phone at this price, though it trails Google and Samsung's 7 years.
• OnePlus does its usual ~1-month post-launch update that fixes some camera issues, and despite overheating reports two reviewers couldn't get their units to overheat in normal use.
• When you buy a phone like the OnePlus 15 you're trusting the software too — and OnePlus's regional operational uncertainty (e.g., India) is a real long-term consideration, though it has promised continued updates.
• The Mind Space feature is a genuine standout that the reviewer uses a lot, and OxygenOS's gaming tools (Game Assist) meaningfully enhance the experience.

Nothing Phone (4a)

Aggressively priced below the Pixel 10a with a more distinctive design and a real telephoto — the standout budget pick for buyers who want personality.

• It's a good chunk of change cheaper than the $500 Pixel 10a.
• It fits the perfect budget for buyers who can't afford the ~$1,000 needed for an entry-level iPhone 17, with good hardware and excellent battery.
• A very strong mid-range smartphone that stands out with unique design, great display, solid performance and surprisingly capable cameras — definitely worth a closer look.
• Nothing stands out among the crowd with a brand identity strong enough to turn consumers into fans.

OnePlus 15

At $899 (12/256) / $999 (16/512), the OnePlus 15 undercuts the $1,000+ Pixel 10 Pro XL, Galaxy S26 Ultra and iPhone 17 Pro Max while matching or beating them on battery, performance and charging. The recurring caveat: it's an outstanding-value flagship that camera-focused buyers may still pass on.

• OnePlus has gone from flagship killer to flagship — available for $899 (12/256) or $999 (16/512).
• It's not trying to be better than everything else — it's trying to be the best phone for $899, and it absolutely nails that, even if cameras are a bit of a letdown.
• I'll just call it the best phone you can buy and the first phone I have tested that deserves a perfect score — OnePlus's best phone, not a step down.
• The honest counterpoint: I'm not angry at the OnePlus 15, I'm just disappointed — the camera and identity sacrifices undercut an otherwise excellent phone.
• From a US perspective the performance and longevity make it a fantastic value compared to the much more expensive $1,000–1,200 offerings from Google, Samsung and Apple — the 'downgrades' are mostly hair-splitting.
• If OnePlus wants to be the flagship killer in the US it still has to give consumers a compelling camera argument — for some, the camera alone kills the deal.
