Nothing Phone (3) Review: Bold Design, Serious Performance

Nothing has done something ambitious with the Phone (3): it's the first device the company has actually called a "true flagship," and the price tag makes that intent explicit. At $799/£799 for the base 12GB/256GB configuration (rising to $899/£899 for 16GB/512GB), it's priced squarely against the Google Pixel 9 and Samsung Galaxy S25 — genuine flagship company, not the flagship-killer positioning Nothing built its name on. The old transparent back and Glyph light strips are gone, replaced by a rear dot-matrix display Nothing calls the Glyph Matrix, and a new dedicated Essential Key launches Essential Space, an AI-powered notes repository that can transcribe and summarise voice memos recorded with a simple flip-and-hold gesture. It's a genuinely different idea, not just a refinement of the old one — and the phone underneath it is a serious, if not class-leading, performer.

Design and the Glyph Matrix

The Phone (3) drops the transparent panel that defined the first two generations. In its place is a glass back with an aluminum frame, and — most notably — a small rear dot-matrix display embedded above the camera module. It's 9.0mm thick and 218g, noticeably heavier than the Phone (2), a difference you'll feel in the hand within the first few days of use. It feels solid rather than delicate, and carries an IP68 rating for dust and water resistance — solid for the category, if a step behind the IP69 pressure-jet resistance some Chinese rivals now offer as standard.

The Glyph Matrix is where Nothing has taken the biggest swing. Controlled by a physical dial button on the back, it can show custom pixel-art animations, a battery/charging readout, a stopwatch, a compass, and even a couple of simple interactive mini-games. It's a smaller, more deliberate feature than the old light-strip notifications — you have to actively engage with it rather than just glance at flashing lights — and whether that's an improvement depends on how much you used the old Glyph Interface day to day. Worth setting expectations here too: only a handful of Glyph Toys were available at launch, a real content gap for what's meant to be the phone's headline feature, though Nothing has opened an API for third-party developers that should broaden the selection over time. After two weeks, I found it a genuinely fun party trick that I used less for practical notification triage than the old lights.

Nothing describes the overall design language as aiming for "technical warmth" — Tom's Guide reported the intent is to recapture some of the nostalgia of beloved tech products like the Game Boy, PlayStation 2, or original iPod, rather than chase the glass-slab sameness of most modern flagships. Whether that lands is genuinely subjective, but it's a coherent, deliberate design philosophy rather than novelty for its own sake — it's the same instinct that made the Glyph Matrix worth building in the first place, even with the transparent back retired this generation. Colour choice stays simple: Black or White, no third option.

Display

The 6.67-inch OLED display at 1260 × 2800 (roughly 460ppi) is sharp and colour-accurate in Natural mode. It's a genuinely good panel with two honest limitations worth knowing before buying. First, brightness: Nothing advertises up to 4,500 nits of peak brightness, but GSMArena's standardised testing measured 756 nits with the slider maxed manually and a healthier 1,507 nits with auto-brightness engaged — plenty for daily outdoor use, but a long way from the marketed figure, which is really an HDR-content ceiling rather than something you'll see in general use. Second, it's LTPS rather than LTPO, meaning no adaptive refresh — the panel steps between 60Hz, 90Hz, and 120Hz but can't drop below 60Hz for static content, a real efficiency trade-off against LTPO rivals at this price. On the plus side, touch sampling runs at 1000Hz and PWM dimming at 2160Hz, both genuinely high figures that translate to snappy touch response and flicker that's imperceptible even to sensitive eyes. Gorilla Glass 7i up front and Victus on the back give it solid everyday durability.

Performance

This is the phone's biggest talking point, and not entirely in a good way. Nothing chose the Snapdragon 8s Gen 4 over a true flagship chip — a deliberate step down from what rivals at this price offer. GSMArena's benchmarking found the CPU performs similarly to the older Snapdragon 8 Gen 3 and MediaTek's Dimensity 9400e, while the Adreno 825 GPU is genuinely competitive, landing close to the Adreno 750 found in the Snapdragon 8 Gen 3. In short daily use, that translates to real, everyday smoothness: apps open quickly and Nothing OS 3.5 runs lean with virtually no overhead.

Sustained performance is a real, more serious weak point than "trails flagship silicon" suggests, and worth being direct about: GSMArena's own testing found the phone thermal-throttles aggressively under sustained load, losing a significant chunk of its peak performance — badly enough that it couldn't even complete a full 3DMark Wild Life Extreme stress-test run. That's a genuinely worse result than most phones in this price bracket, flagship or not, and a heavier caveat than a simple "step below rival silicon" framing implies. In short gaming sessions and everyday tasks this is largely invisible, but anyone planning extended gaming sessions should temper expectations accordingly. Software support is a genuine bright spot to offset this, though: Nothing has confirmed five years of major OS upgrades and seven years of security patches — a real jump from the Phone (2)'s four-and-four, and among the longer commitments in the category regardless of chipset.

The dedicated Essential Key is the other software talking point. Press and hold it while flipping the phone over and it starts recording, later transcribing and summarising whatever was said into Essential Space — a centralised, AI-indexed notes repository Nothing has continued expanding post-launch with Google Calendar sync and editable memory entries. It's a genuinely different idea from a generic voice-memo app, though at launch it's still closer to a promising foundation than a fully mature feature.

Real-world reports on day-to-day smoothness are mixed rather than unanimous, worth noting honestly rather than picking the more flattering account. SlashGear's testing (Geekbench scores of 2,134 single-core / 7,081 multi-core, respectable for the chip) noticed occasional stutters, most often in the camera app, though the reviewer stopped short of pinning that specifically on the processor rather than software optimisation. That sits alongside Tech Advisor's more positive account of zero hesitation switching between apps. The honest takeaway: this is a phone that's smooth the large majority of the time, with occasional rough edges that a future software update could plausibly resolve.

Camera

A 50MP main sensor with optical image stabilisation, a 50MP periscope telephoto (3x optical, also OIS), and a 50MP ultrawide — all identically rated at 50MP, which Nothing leans into as a design philosophy. Daylight images are clean and well-processed, with Nothing continuing to move away from the over-sharpened look of the Phone (2). Android Authority's hands-on testing praised the main camera specifically in late-day, low-angle light, and found portrait mode tracing subjects reliably even in fairly busy scenes. The 3x macro mode is a genuine nice touch, borrowing the telephoto sensor rather than the ultrawide the way many rivals do, which means closeup shots hold onto real detail rather than the mushy softness a repurposed ultrawide macro often produces.

Low light is competent but not in the same league as the Pixel 10 Pro, which GSMArena's own competitive analysis credits with meaningfully stronger computational photography and a longer telephoto reach. Video tops out at 4K60 with HDR10+ support, and both the main and telephoto cameras carry OIS, which noticeably steadies handheld footage compared to the ultrawide's electronic-only stabilisation. The 50MP front camera is fixed-focus rather than autofocus — a minor compromise for close-up selfies, but adequate for everyday video calls.

Battery

A 5,150mAh battery (5,500mAh on Indian units), built around silicon-carbon cell chemistry that packs more capacity into the same physical footprint than a conventional battery, with 65W wired charging and 15W wireless. Real-world battery life is strong — PhoneArena's testing clocked around 9 hours in its gaming benchmark and roughly 10 hours of continuous video playback, and day-to-day use comfortably lasts a full day with charge to spare. Charging is a case of the spec sheet overpromising, though: GSMArena's own power-draw testing found the phone never actually pulls anywhere near its rated 65W in practice, landing closer to 40W throughout the charge cycle — quick enough for a convenient top-up, just not the number Nothing advertises on the box. There's no bundled charger in the box either, so budget for a separate PPS-compatible brick if you don't already own one capable of the phone's real-world draw.
