Nothing Phone (4a) vs Samsung Galaxy S26 Ultra

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.

Samsung Galaxy S26 Ultra

Underneath the Privacy Display tech, the panel is the familiar 6.9-inch QHD+ Dynamic AMOLED 2X at 1–120Hz LTPO with 2,600 nits peak brightness (lab-confirmed closer to 3,000) and Gorilla Armor 2 anti-reflective coating. The hardware specs barely changed; what's controversial is whether the new panel structure subtly degrades the always-on viewing experience versus the S25 Ultra's reference panel.

• 6.9-inch Dynamic AMOLED 2X panel at 3,120 × 1,440, 1–120Hz LTPO, 2,600-nit peak claim — same nominal specs as last year
• Lab measurement at Linus Tech Tips actually hit 2,997 nits peak — Samsung is 'underselling' the panel's brightness
• MKBHD notes the panel is still 8-bit simulating 10-bit color and that the anti-reflective coating is 'not quite as good at the anti-reflective thing' as the S25 Ultra
• Verge sees more color shift on the S26 Ultra than the S25 Ultra when viewing from a very low angle, even with Privacy Display off
• Out of the box the phone is configured to 1080p for battery; switching to 1440p is a one-time settings change every reviewer recommends
• TechRadar still considers the panel 'class-leading' for outdoor visibility, HDR playback, and stylus latency in 2026
• Trusted Reviews calls it 'easily the best screen around — or at least it will be until it's inevitably copied by the competition'
• Gorilla Armor 2 with ceramic-infused glass keeps reflections way down and survived PBKreviews' four bare-concrete drops without cracking

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.

Samsung Galaxy S26 Ultra

Same sensors as the S25 Ultra (200MP main 1/1.3in, 50MP ultrawide, 10MP 3x telephoto, 50MP 5x periscope, 12MP selfie) but the main and 5x get wider apertures (f/1.4 from f/1.7; f/2.9 from f/3.4). Reviewers agree the low-light gain is real and visible without leaning on AI. New software tricks: APV codec for near-lossless 1080p/4K video, Horizon Lock super-stabilization, and an expanded Photo Assist with generative editing. The unloved 10MP 3x sensor and AI-aggressive 30x+ zoom are the recurring weak points.

• 200MP main with new f/1.4 aperture lets the sensor 'collect more light, resulting in quicker exposures with less motion blur' — Verge confirms lower ISO and faster shutter speeds than the S25 Ultra in side-by-side testing
• Forbes' two-week test on low-light cat photos found 'much more vivid colors' and 'sharper details with more enhanced shadows' versus the S25 Ultra — 'the difference feels truly drastic'
• Engadget's challenging backlit Grogu shot showed the S26 Ultra outperform a Pixel 10 Pro on subject exposure — 'managed to make an already great main camera just a bit better'
• 10MP 3x telephoto is dated and the only zoom range where image quality visibly sags — Trusted Reviews calls it 'particularly dated' compared to Oppo's 200MP zoom in the Find X9 Pro
• Ars Technica notes shots 'tend to look a bit overprocessed in the 3x to 4.9x zoom range' because the 10MP sensor can't keep up between the 1x and 5x optical primes

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.

Samsung Galaxy S26 Ultra

Snapdragon 8 Elite Gen 5 for Galaxy, paired with 12 or 16GB RAM and up to 1TB storage, comfortably tops every published Android benchmark and trades blows with the iPhone 17 Pro in single-core. A redesigned, larger vapor chamber keeps sustained performance up, though Wild Life stress runs still shed 30-40% of peak GPU output under load.

• Engadget records a Geekbench 6 multi-core score of 11,240 (vs 9,828 on the S25 Ultra) and GPU score of 25,403 — the fastest Android scores currently published
• Trusted Reviews measured 3DMark Wild Life Stress Test stability at 67.6% — a big jump from the S25 Ultra's 58.4% and ahead of the Honor Magic 8 Pro (55.4%)
• Ars Technica records the S26 Ultra topping all benchmark charts on paper but losing 'about 40 percent of its graphical performance' under prolonged stress
• Linus Tech Tips' stress test showed the S26 Ultra outperforming an iPhone 17 Pro by ~34% and a OnePlus 15 by ~5%, but flagged that it 'gradually gets worse over time' as thermal throttling kicks in
• 39% NPU improvement enables on-device Galaxy AI features without round-tripping to the cloud — Ars praises the 'local-only private AI processing' toggle
• Android Authority confirms the S26 Ultra holds Wild Life Extreme leadership over the OnePlus 15 for the first 12 loops before settling 'just a hair behind' — a meaningful reversal from the S25 Ultra era
• Genshin Impact at max settings ran at a 'mostly solid 60 FPS' on LTT's review unit, with occasional hitching once the chassis got noticeably warm in hand
• Sustained 30-minute heavy-workload test by a YouTube benchmarker showed the S26 Ultra ahead of iPhone 17 Pro Max in multi-core throughput but losing on efficiency — 11% battery usage on iPhone vs more on the S26

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.

Samsung Galaxy S26 Ultra

The S26 Ultra inherits the same 5,000 mAh capacity Samsung's used since the S20 Ultra — six years unchanged — but 60W wired charging is genuinely faster and Qi 2.2 25W wireless is overdue. Reviewers split: most say battery life is 'fine' but no longer flagship in a market where OnePlus 15 ships with 7,300 mAh and Oppo Find X9 Pro packs 7,500 mAh. Charging speeds are now a competitive feature, not a weakness.

• Same 5,000 mAh battery as the S25 Ultra, S24 Ultra, S23 Ultra, S22 Ultra, S21 Ultra and S20 Ultra — 9to5Google calls this 'easily the most egregious spec Samsung hasn't changed'
• Phone Arena's real-world diary measured average 100% screen time at just 6 hours 1 minute — 'just not very impressive' next to iPhone 17 Pro Max's nearly 9 hours on the same test
• Engadget's local video rundown measured 30 hours 3 minutes — only ~30 minutes longer than the S25 Ultra; chip efficiency gains, not capacity, are doing the work
• 60W wired charging: 0-50% in 18-19 minutes, 0-75% in 30 minutes, 0-100% in 47-53 minutes across multiple independent tests
• Mrwhosetheboss' charging test confirmed 47 minutes 0-100% versus 1 hour 19 minutes for the iPhone 17 Pro Max — a 32-minute charging gap in Samsung's favor
• Wireless charging upgraded to Qi 2.2 25W but built-in Qi2 magnets are still missing — Ars Technica says you 'can add that functionality back in by choosing the right case, but that's not a very premium experience'
• Trusted Reviews' MWC use case 'had to top up the phone every single day with my power bank', 'never once making it through a full day' under heavy travel
• 1-month long-term reviewer found average usage of 46-47 hours between charges with light-to-moderate use — closer to 2 days when on Wi-Fi all day with no GPS
• Owner-comparison post on r/OnePlus: S26 Ultra battery 'wasn't getting me through a full day sometimes' after 2 months — OnePlus 15's 7,300 mAh got the user back to ~59% at end of heavy first day
• Engadget calls Samsung's continued omission of Qi2 magnets 'the major annoyance' and hopes 'this is the last time' the flagship ships without them

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.

Samsung Galaxy S26 Ultra

One UI 8.5 ships on Android 16 with seven years of OS + security updates promised. Beyond the new transparent glass UI choices, the story is Galaxy AI — Now Brief, Now Nudge, Photo Assist, Creative Studio, summarized notifications, plus Gemini task automation (beta) for limited ride-share and food-delivery flows. Reviewers split sharply on whether the AI features are genuinely useful or 'slop', but a local-only AI processing toggle gets near-universal praise.

• Seven OS upgrades and security patches take the phone through to Android 23 in 2033 — Trusted Reviews calls it 'one of the strongest long-term Android bets around'
• Now Nudge is Samsung's Magic Cue clone for proactive contextual suggestions — Verge saw it work a couple times but Ars Technica 'haven't seen a single Nudge appear in my testing'
• Gemini task automation can open Uber/DoorDash and complete the flow up to the final confirm tap — Ars says it 'usually got there, asking me to tap the final order button after a lengthy wait'
• Photo Assist's natural-language editing is powerful but unsettling — Verge could 'remove my husband's shirt' and 'paste celebrities into selfies'; the Engadget Pikachu sticker test was outright strange
• MKBHD calls most of the AI 'slop' — useful features like call screening and Audio Eraser get praise but Galaxy AI is 'not a reason to buy this phone'

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.

Samsung Galaxy S26 Ultra

At $1,300 starting (256GB), $1,499 (512GB), $1,799 (1TB), the S26 Ultra still costs more than the OnePlus 15 ($899 with double the storage), the Pixel 10 Pro XL ($1,199), and the iPhone 17 Pro Max ($1,199). Reviewers position the value case around the privacy display, the camera versatility, the seven-year update window, and the One UI ecosystem rather than raw spec-for-spec parity.

• Starting MSRP held at $1,299 — but 512GB jumped to $1,499 (from $1,419) and 1TB to $1,799 (from $1,659) versus the S25 Ultra
• OnePlus 15 at $899 includes 512GB + 16GB RAM + 7,300 mAh battery — 'you cannot beat that' value, per a side-by-side owner on r/OnePlus
• Engadget calls the $1,300 hold-the-line price 'almost a blessing' given component-cost inflation across the industry in 2026
• Trade-in offers worsened sharply after pre-order — 9to5Google describes trade values that 'fell off a cliff' and perks like doubled storage 'vanished this time around'
• Phone Arena says the Ultra is still 'the phone to buy in 2026' if you value slim design, One UI refinements, and Samsung's overall ecosystem reliability — but rivals 'pull further ahead' on cameras and battery life
• Ars Technica frames the long-term value case: 'fast enough out of the box that it could remain usable all the way to the end of its seven-year update lifespan'
• Forbes recommends skipping the Ultra and grabbing the S26 Plus or base S26 'if you don't need every single feature — most notably, the Privacy Display'
• Comparison vs iPhone 17 Pro Max: Ultra wins on display, AI flexibility, and zoom; iPhone wins on battery efficiency, ecosystem cohesion, and video color science
