1. Design & The Refined Glyph Bar

The Nothing Phone 4b introduces a highly acclaimed unibody design inspired by the Phone (4a) Pro, featuring a UV-treated, soft-touch coating for a premium in-hand feel. The transparent back beautifully exposes the mechanics of the camera bump and is crafted with clear thermoplastic polyurethane. The phone is available in Black, White, and Blue, alongside a striking exclusive red RCB edition in India to celebrate the team's historic IPL title. It also features incredible durability, being 20% more bend-resistant than the Phone (3a) Lite and carrying an IP64 rating, allowing it to withstand up to 25cm of water for 20 minutes.

But the true centerpiece of the device is the refined Glyph Bar. Continuing Nothing's signature look, it now packs 45 individually controlled mini-LEDs that can hit an eye-watering peak brightness of 3,500 nits, making it 40% brighter than previous generations. This interface lets you track deliveries, timers, and charging updates without looking at the screen. Furthermore, Nothing has included a traditional film-inspired red recording light on the Glyph Bar, letting others know precisely when you are filming.

2. Performance & Gaming

Under the hood, the Phone 4b takes a massive leap forward powered by the Snapdragon 6 Gen 4 processor, built on a highly efficient 4nm process. This setup delivers 15% faster CPU performance and a 25% boost in graphics compared to older models. To handle extended workloads, it is equipped with a massive 4,400 mm² vapor chamber cooling system that keeps the device running smoothly and cool during heavy operations. Furthermore, Qualcomm’s 6th Generation AI Engine enables on-device AI processing that is up to 240% faster.

For gamers, the experience is visualized on a vibrant 6.77-inch Super AMOLED display featuring a 120Hz adaptive refresh rate and 2,000 nits of peak brightness. Combined with a 1,000Hz touch sampling rate for ultra-responsive control, the Phone 4b is optimized for serious play. Users can enjoy silky-smooth 120 FPS gameplay in titles like Subway Surfers and League of Legends: Wild Rift, and up to 90 FPS in demanding games like BGMI and CODM.

3. Cameras & Essential AI Integration

The photography setup is headlined by a 50MP OIS main camera alongside a 119-degree ultra-wide lens, ensuring stable, expansive shots. The hardware is driven by Nothing’s TrueLens Engine 4, which leverages Ultra XDR imaging by automatically combining 13 RAW frames to produce brilliant highlights and true-to-life shadows. For videography, the phone supports steady 4K recording at 30fps and introduces Dual Video Capture for the first time, allowing you to record with both the 16MP front camera and the rear camera simultaneously.

On the software front, the device launches with Nothing OS 4.1 (based on Android 16) and boasts a segment-leading promise of 3 years of OS updates and 6 years of security patches. It’s packed with "Essential AI" tools that require zero compromises. Users have native access to ChatGPT and Google Gemini integrated right into the clipboard and UI. Additionally, features like Essential Voice for intelligent dictation, Essential Space for organizing screenshots and notes, and the Essential Apps Builder allow users to command their phone using simple, everyday language.

4. Battery Life & Charging

Battery anxiety is a thing of the past with the Nothing Phone 4b, which is officially Nothing's longest-lasting smartphone ever. The global model is equipped with a robust 5,200 mAh battery, while users in India get an exclusive, massive 6,000 mAh cell. This means the phone can easily push through up to two full days on a single charge. Specifically, the 5,200 mAh variant is rated to deliver 46 hours of call time, 34 hours of music, and up to 22 hours of continuous video streaming.

When the battery finally runs low, the device supports 33W fast charging to get you back in action quickly. This charging speed allows the phone to hit 50% capacity in under 30 minutes, and complete a full 100% charge in just over an hour. Whether you are pushing the Snapdragon processor with intensive gaming or running high-level AI tasks, this battery setup ensures you won't be tethered to a wall outlet.
