Nothing launches a new affordable model, Nothing Phone 4(b). This product, priced at $2899, is regarded as a continuation of the earlier CMF series and is positioned under the Nothing Phone 4(a) in the product line. As the brand’s first “b” series mobile phone that focuses on the people-friendly route, Nothing Phone 4(b) attempts to strike a balance between cost control and the brand’s iconic unique design, providing a unique choice for consumers with limited budgets.
In terms of appearance design, Nothing Phone 4(b) maintains the brand’s consistent industrial style and futuristic sense of technology. The body is made of polycarbonate and is available in black, white and powder blue. The back of the phone is equipped with a rectangular camera module that occupies a large area and is embellished with exposed screws, creating a visual effect like mechanical parts in science fiction movies. Although the materials used tend to be entry-level, the overall workmanship is solid and there is no loose feeling that is common in cheap mobile phones.
The brand’s iconic Glyph Bar lighting system is retained on the right side of the back. Although the scale has been reduced for higher-end models, it can still flash notifications for specific contacts, display charging progress, or countdown the camera.
In addition, an Essential Key is added to the left side of the fuselage, allowing users to quickly take screenshots and add voice or text memos. In terms of protection level, the machine has IP64 dust-proof and waterproof certification, which can handle daily light rain or water splash.
The screen configuration is a major feature of Nothing Phone 4(b). The machine is equipped with a 6.77-inch Super AMOLED display with a resolution of 1080 x 2344 and supports a dynamic update rate of up to 120Hz. The peak brightness of the screen can reach 2000 nits, which can still maintain a clear reading experience under outdoor sunlight. In order to extend the life of the screen, the manufacturer has added pixel fine-tuning technology to reduce the risk of AMOLED burn-in. The bottom of the screen is equipped with an optical fingerprint unlocking function. Although the response is not as fast as the ultrasonic technology of flagship phones, it still provides an accurate and stable unlocking experience in daily use.
▲There is a 16-megapixel selfie lens above the screen
▲There are dual SIM card slots and USB Type C slot at the bottom of the fuselage
▲There are power button and volume button on the right side of the fuselage
▲Nothing OS 4.1 is based on Android 16. The interface continues the minimalist style, and adds practical functions such as monochrome themes and lock screen customization.
▲The most noteworthy thing is Essential Space. Through the exclusive physical key (Essential Key), users can quickly record voice, text or image notes, and they will be automatically organized and searched by AI.
▲Nothing OS has a “Glyph” lighting interface, allowing users to choose how the ringtone and incoming call lights shine.
In terms of hardware specifications and performance, Nothing Phone 4(b) is equipped with a Snapdragon 6 Gen 4 processor and provides a single configuration of 8GB of memory and 128GB of storage space. In daily operations, with the Nothing OS system based on Android 16, basic applications such as sliding the overall interface, opening social media or streaming videos are very smooth. However, this chip has always been positioned as a mid- to low-end chip. When processing large-scale 3D games, you need to lower the image quality settings to maintain a stable frame rate. For users who pursue ultimate performance, there may be more powerful options in the same price range on the market, but for general daily use, the computing power of Nothing Phone 4(b) can already meet basic needs.
▲In addition, RAM Booster technology can expand the memory to 16GB (physical + virtual). For users who frequently use multiple social software and games, the background retention rate will be improved.
In terms of photography capabilities, Nothing Phone 4(b) uses a dual-lens combination, including a 50-megapixel main lens (f/1.8 aperture) that supports optical image stabilization, and an 8-megapixel ultra-wide-angle lens (f/2.2 aperture).
In the default 12-megapixel mode, the main lens can take photos with natural colors and well-preserved details. Users can also manually switch to 50-megapixel mode to obtain higher dynamic range and resolution. However, due to the lack of a physical telephoto lens, there will be a significant drop in image quality when performing digital zoom of two or three times more. The front-facing 16-megapixel selfie lens performs smoothly and provides accurate skin tone restoration, while video recording supports up to 4K 30fps, which is suitable for daily recording of life clips.
Battery life is the most outstanding aspect of Nothing Phone 4(b). The fuselage has a built-in battery of up to 5200mAh. In actual tests conducted abroad, it can provide nearly 17 hours of continuous use, which means that even heavy users can easily meet the needs of a whole day without the need for frequent charging. The box comes with a transparent protective case and USB-C cable, but does not provide a charger, which is also a common practice in the industry. The manufacturer promises to provide three years of operating system updates to ensure that the mobile phone will still have the latest software functions and security guarantees in the future.
To sum up, Nothing Phone 4(b) is an entry-level smartphone with a very recognizable appearance and strong battery life. It does not use the top processor, nor is it equipped with a full-focus camera module, but it provides a smooth system experience, a high-quality AMOLED screen and a unique Glyph lighting design at a reasonable price. For consumers who have limited budget, have requirements for mobile phone design, and pay attention to daily battery life, Nothing Phone 4(b) is a feature worth considering.
