Nothing Phone 4B Review | Should You Buy It or Not?

720p display. IPS LCD panel. 4GB RAM. These are three things you never want to hear about a new phone — and the good news is the Nothing Phone 4B has none of them. This is Nothing's most affordable phone yet, part of a brand-new "B series" line, and I spent a full week using it as my daily driver. Here's my honest, point-by-point breakdown.

1Design and Build Quality

Unbox it and your first thought will probably be "this looks a lot like the Phone 4a Pro" — and you'd be right. Here's what stands out:

• Familiar design: Nearly identical back panel to the 4a Pro, but the dimple near the camera now lines up properly with the cutout
• Plastic unibody: No metal this time, but it still feels premium in hand, not cheap
• Weight: 210g — not the lightest, but it doesn't feel tiring to hold
• Glyph Lights: Five vertical LED squares instead of seven, but brightness and functionality are unchanged, and the red recording LED is still there
• Durability: IP64 rated for light splashes, Dragontrail glass on front, with a pre-applied screen protector in the box
• Colours: Blue, white, and black — blue is my personal favourite

2Display and Speakers

This is where you'll spend most of your time, and Nothing hasn't cut corners:

• Panel: 6.77-inch, 1080p AMOLED with 120Hz refresh rate and an optical in-display fingerprint scanner
• Brightness: Hit 1,800 nits in testing — even higher than Nothing's official claim, and easily readable in direct sunlight
• HDR playback: Looks sharp and vivid on both YouTube and Prime Video
• Speakers: Proper dual stereo speakers that sound louder and fuller than you'd expect at this price, thanks to a dedicated top speaker grille instead of just the earpiece
• Bezels: Thinner on top and sides than the CMF Phone 3 Pro and Phone 3 Lite, though the chin is a touch thicker
• Extras: Always-on display included

3Performance

A full week of daily use, and the phone stayed reliably smooth. Here's the breakdown:

• Chip: Snapdragon 6 Gen 4, paired with 8GB RAM even on the base variant
• Storage: 128GB or 256GB, UFS 2.2 with LPDDR4X RAM
• Benchmarks: Just above 1 million on AnTuTu
• Real-world test: Handled Android Auto, hotspot tethering, music, and app-switching over a 2-hour drive without heating up or slowing down
• Gaming: Steady 90 FPS in Call of Duty Mobile and BGMI; struggles with heavier titles like Genshin Impact
• Minor issues: Animations aren't quite as smooth as the 4a/4a Pro, and the camera preview occasionally doesn't rotate correctly — likely fixable with a software update

4Software

Runs on Nothing OS 4.1 based on Android 16. Key points:

• Update promise: 3 years of OS updates and 6 years of security patches
• Clean experience: No ads, no lock screen clutter — just 3 uninstallable pre-installed apps (Facebook, Instagram, Amazon Music)
• Essential Voice: Converts speech into formatted text inside any app with a keyboard — long-press the Essential key to use it, and it can translate on the fly
• Glyph live activities: Track things like a Zomato delivery right on the Glyph strip
• Haptics: The weak point — vibrations are there but easy to miss, and cranking up the intensity makes them feel too harsh instead of better

5Camera

A simple three-camera setup: 50MP main with OIS, 8MP ultrawide, and a 16MP selfie camera.

• Daylight: Punchy colours, well-handled HDR, genuinely pleasant photos
• Zoomed-in shots: Noticeably softer, with less fine detail
• Indoor shots: Surprisingly good in several test shots
• Night photos: Decent colour reproduction, but grain and softness appear once you zoom in
• Portraits: Skin tones could be better, though edge detection is solid
• Video: 4K at 30fps with rich colours, plus a dual capture mode for simultaneous front and rear recording, and decent walking stabilisation

Verdict: Not the best cameras in this segment, not the worst either — solidly in the middle.

6Battery and Charging

This is where the 4B genuinely stands out:

• Battery size: 6,000mAh — the biggest Nothing has ever fitted into a phone
• Real-world use: Comfortably lasts more than a day with normal use
• Screen-on time: Averaged around 6.5 hours in testing (Instagram, YouTube, gaming, photography)
• Charging speed: Up to 33W, taking about 1 hour 40 minutes from 20% to 100%

7Connectivity

• Network: No call drops or connectivity issues on either Airtel or Jio
• Included: Wi-Fi 6, Bluetooth 6, and support for nine 5G bands
• Missing: No NFC, no eSIM support in India, and no microSD card slot

8Nothing Phone 4B Price and Verdict

For that price, you get 8GB RAM on the base model, a 1080p AMOLED display, a main camera with OIS, good stereo speakers, a huge battery, and strong software support.
