This Nothing Phone 4b review looks at the first device in Nothing’s brand new budget focused b-series, a phone built to sit below the Phone 4a while still carrying the brand’s signature transparent look. Nothing unveiled the Phone 4b globally on July 7, 2026, and it’s already raising an interesting question. Is this actually a smart buy, or is it stuck in an awkward spot between Nothing’s own cheaper and pricier phones?
We went through the specs, the pricing across different regions, and how it stacks up against the Phone 4a to help you figure out where it actually fits.
What the Phone 4b Actually Is
Nothing has covered the entry level segment through its CMF sub-brand for the past couple of years, but rising costs for RAM and flash storage made a new CMF phone impractical for 2026. Instead of raising CMF prices or cutting corners on that line, Nothing decided to bring the budget segment under its own main brand, creating an entirely new b-series that sits below the a-series.
That’s a meaningful structural shift. Rather than juggling two separate sub-brands, Nothing now has a cleaner three tier lineup: the b-series as the true entry point, the a-series as the upper mid-range, and its flagship Phone line above that. It’s a tidier way to organize things, and it also means the Phone 4b gets to keep Nothing’s actual design language rather than the more toned down CMF aesthetic.
Release Date and Where You Can Buy It
Nothing officially unveiled the Phone 4b on July 7, 2026, alongside the Nothing Ear (3a) earbuds, through a global livestream event. The rollout isn’t happening everywhere at once, so here’s what’s confirmed region by region.
In India, the phone went on sale July 14, 2026, through Flipkart and retail partners including Croma, Reliance Digital, and Vijay Sales, priced at 34,999 rupees. In Europe, Nothing confirmed pricing for Germany, Austria, and Switzerland, with the phone starting at 329 euros. In the UK, it’s priced at 299 pounds and expected to go on sale around July 17, 2026. As for the US, Nothing has confirmed the Phone 4b will skip the North American market entirely, so American buyers won’t be able to purchase it through official channels.
Full Specs Breakdown
Here’s what you’re actually getting for the price. The Phone 4b has a 6.77-inch FHD+ LTPS AMOLED display with a 120Hz refresh rate and peak brightness of 2,000 nits, along with 1,000Hz touch sampling and 480Hz PWM dimming. There’s an in-display optical fingerprint sensor built into the screen.
Under the hood is a Qualcomm Snapdragon 6 Gen 4 chip built on a 4nm process, paired with an Adreno 810 GPU. That’s a step down from the Phone 4a’s Snapdragon 7s Gen 4, so expect solid everyday performance rather than flagship level speed. You get 8GB of LPDDR4X RAM across the board, with a choice of 128GB or 256GB of UFS 2.2 storage and no card slot for expansion.
Camera wise, there’s a 50MP main sensor and an 8MP ultrawide on the back, plus a 16MP front facing camera. Notably, the Phone 4b drops the telephoto lens found on the Phone 4a, which is one of the clearer trade-offs for the lower price.
Battery capacity depends on where you buy it. The Indian version gets a 6,000mAh battery, which Nothing says is the largest it’s ever put in a phone, while the global version gets 5,200mAh. Both support 33W wired charging, getting you to 50 percent in under half an hour, plus 7.5W reverse wired charging so you can top up accessories on the go. A 4,400mm² vapor chamber helps manage heat during extended use or light gaming.
Design and Build Quality
The Phone 4b keeps Nothing’s signature transparent style, with a partially see through back panel and camera module that shows off some of the internal components underneath. Instead of the older segmented Glyph interface found on earlier Nothing phones, the 4b introduces a redesigned Glyph Bar, a slimmer strip of LEDs built directly onto the camera module, made up of several rectangular LED segments that still handle calls, notifications, and charging progress.
The phone uses a polycarbonate unibody design borrowed from the Phone 4a Pro, weighs around 210 grams, and measures 8.6mm thick. It carries an IP64 rating, so it can handle dust and light splashes, though it’s not built for full submersion. Nothing states the build resists bending about 20 percent better than the earlier Phone 3a Lite, and the polycarbonate shell resists fingerprints better than a typical glossy glass back.
It comes in Black, White, and Blue, and Nothing also released a matte red RCB Edition exclusive to India, made in partnership with the Royal Challengers Bengaluru cricket team, featuring the team’s logo prominently on the back.
Software and Long Term Support
The Phone 4b ships with Nothing OS 4.1 running on top of Android 16 out of the box. Nothing has committed to 3 years of major Android OS updates and 6 years of security patches, which is a genuinely long support window for a phone at this price point, and it matches the kind of commitment you’d typically expect from a considerably more expensive device.
Nothing OS has built a reputation for staying close to stock Android while adding its own distinctive visual touches, things like custom fonts, widget styles, and the Glyph integration. If you’ve used a Nothing phone before, the 4b will feel immediately familiar. If you haven’t, it’s one of the cleaner Android skins currently available, without the bloatware that weighs down a lot of budget phones from other brands.
How It Compares to the Nothing Phone 4a
If you’re trying to decide between the Phone 4b and its more expensive sibling, here’s how they stack up. The Phone 4b costs less, and in India it actually packs a bigger battery than the 4a. In exchange, you lose the telephoto camera entirely, get a lower resolution selfie camera, slower charging speeds, and a less powerful chipset. RAM also caps out at 8GB on the 4b, while the Phone 4a can be configured with up to 12GB.
For context, Nothing has also confirmed that the Phone 4a itself starts at roughly $421.60 with the Phone 4a Pro at around $527.02 following a recent price increase, which puts the Phone 4b firmly and clearly below both in terms of positioning.
The honest assessment here, echoed by several early reviewers, is that it’s genuinely difficult to recommend buying the Phone 4b over the Phone 4a in markets where both are available around a similar price, since the 4a simply offers more for not much more money. Where the Phone 4b makes more sense is in markets like India, where the price gap between the two is wider and the 4b’s bigger battery becomes a real selling point rather than just a consolation prize.
Camera Performance in Real Use
The dual camera setup won’t compete with flagship phones, but for a budget device it holds up reasonably well in daylight conditions. The 50MP main sensor produces sharp, well exposed photos outdoors, with colors that lean slightly warm and pleasing rather than clinically accurate. Low light performance is where the limitations of a budget sensor and processor combination become more obvious, with noticeably more grain and slower shutter response in dim environments.
The lack of a telephoto lens is the biggest camera related sacrifice compared to the Phone 4a. If zoomed in photography matters to you, that’s worth factoring into your decision, since the ultrawide lens can’t compensate for the missing zoom range.
Battery Life and Charging in Daily Use
Given the size of the battery, especially in the Indian 6,000mAh variant, all day battery life shouldn’t be a concern for most users, even with moderate to heavy use. Early hands on impressions describe the phone comfortably lasting through a full day of typical use, including messaging, browsing, streaming, and some gaming, with battery to spare heading into the evening.
The 33W charging speed is respectable without being class leading. Getting to 50 percent in under 30 minutes is convenient for a quick top up before heading out, though it won’t match the fastest charging speeds available on some competing budget phones from Chinese brands.
Who Should Actually Buy This
The Phone 4b makes the most sense for a few specific buyer types. Anyone in India looking for a phone with genuinely excellent battery life and Nothing’s distinctive design at a reasonable price gets real value here, especially with the larger 6,000mAh battery exclusive to that market. Buyers in Europe who specifically want Nothing’s design language at the lowest possible price point, and who don’t mind giving up the telephoto camera and some RAM, are another reasonable fit.
On the other hand, if you’re in a market where the Phone 4a is available at a similar or only slightly higher price, it’s genuinely hard to justify picking the 4b over it. And if you’re in the US, the decision is made for you, since the Phone 4b simply isn’t launching there.
Is the Nothing Phone 4b Worth Buying?
The honest answer depends heavily on where you live and what else is available at a similar price. On its own, the Phone 4b is a perfectly competent budget phone with a distinctive look, long software support, and strong battery life, especially in its Indian configuration. It doesn’t feel like a “cheap” phone in hand, and the transparent design remains one of the more visually interesting choices in the budget category.
Where it runs into trouble is context. Nothing’s own Phone 4a exists at a price point close enough that it often makes more sense to spend a little more and get a meaningfully better camera, faster charging, and a more powerful chipset. If you’re set on staying at the absolute lowest price Nothing offers, though, the Phone 4b is a genuinely solid pick, just go in aware of exactly what you’re trading away to get there.
