Nothing Phone 4b Review: Big-Screen Battery Champ on a Budget

Verdict: A Mid-Range Phone That Feels Flagship Where It Counts

The Nothing Phone 4b is a mid-range smartphone that combines a 6.77-inch 120Hz AMOLED display, long-lasting battery, distinctive Glyph LED design and Snapdragon 6 Gen 4 processor to deliver affordable flagship features at a lower price bracket than many rival devices.

This is not a spec monster; it is a value play. For around £299/€329/₹35,000, the Nothing Phone 4b gives you a 120Hz AMOLED screen, a huge 5,200mAh or 6,000mAh battery, and a distinctive design that most mid-range slabs cannot match. The trade-off is clear: performance and charging speeds sit a step below premium, and the software support window is shorter than some big-name rivals. If you care more about display quality, battery life and style than raw benchmark numbers, this phone punches above its weight; power users and long-term upgraders may want to look elsewhere.

Display and Design: Flagship Look, Mid-Range Materials

The headline feature of the Nothing Phone 4b is its 6.77-inch OLED panel with a 120Hz refresh rate, up to 1,200 nits in outdoor mode and 2,000 nits peak brightness. It supports HDR10+, and the combination of size, smoothness and brightness means you are looking at a screen level that many premium phones charge much more for. This is where the 4b most convincingly delivers affordable flagship features: scrolling is silky, gaming feels responsive, and HDR content looks lively without needing an expensive flagship.

Nothing’s design language remains a major differentiator. The Phone 4b uses a polycarbonate unibody with transparent cues, visible screws and metal-like elements, plus a CMF-style circular indent on the rear plastic panel. It is rated IP64, so it can resist dust and splashes. On the back, a wide camera island houses the dual-camera setup and the Glyph Bar: a vertical light bar with 45 mini-LEDs and four white plus one red segments that can show timers, recording status, charging progress and personalized alerts. This makes notifications and timers tactile in a way flat black rectangles from other brands do not.

Battery Life and Charging: Big Cells, Modest Speeds

Battery is where the Nothing Phone 4b goes from good to standout. The global model carries a 5,200mAh battery, while another variant steps up to 6,000mAh. According to one source, the 5,200mAh pack supports up to 22 hours of continuous video streaming and is the highest capacity used in a Nothing Phone so far. There is also a bold durability claim: the cell is rated for 1,200 charging cycles before dropping to 90% capacity, beating the 1,000-cycle/80% figures often cited by bigger brands. For anyone focused on mid-range phone battery life, this is a compelling combination of capacity and longevity.

The price you pay is slower charging. Both battery variants top out at 33W wired-only charging plus 7.5W reverse charging. One report notes a complete charge in about 80 minutes, which is described as slow by current standards. You will not get the 15–30 minute top-ups some fast-charging rivals offer, but you also will not need to charge as often. Reverse charging is a nice bonus if you carry wireless earbuds or accessories. For most users, this is a sensible trade-off: conservative charging speeds that should extend battery health over the life of the phone.

Performance, Cameras and Software: Smart Compromises for the Price

Under the hood, the Nothing Phone 4b runs the Snapdragon 6 Gen 4 paired with 8GB of LPDDR4X RAM and UFS 2.2 storage in 128GB or 256GB flavours, depending on region. Qualcomm claims an 11% CPU uplift and 29% GPU boost over the Snapdragon 6 Gen 3 thanks to newer Cortex-A720 and Cortex-A520 cores and an updated GPU and NPU. In practice, this chip sits between Nothing’s own 3a Lite and 4a series: smoother than older Dimensity-based models but behind Snapdragon 7s Gen 4 devices for heavy gaming. For day-to-day apps, social media and light gaming, it feels balanced; aspiring e-sports players should consider more powerful silicon.

Camera hardware is straightforward: a 50MP main sensor (1/2.76-inch) with f/1.8 lens and OIS, flanked by an 8MP ultra-wide with around a 119–120° field of view, plus a 16MP selfie shooter. The main camera records 4K at 30fps or 1080p at 60fps and supports dual capture with front and rear cameras together. This setup will not rival high-end multi-sensor arrays, but for most social sharing and everyday snaps, it “gets the job done” as one source puts it. Nothing OS 10.1 adds Glyph customization and Essential Key shortcuts to trigger voice, search and other AI features, though overall OS support is limited to three years, with security patches planned for six.
