Nothing Phone 4a vs 4b: What's the Difference, and Which One Is Better?

The Nothing Phone 4a vs 4b comparison gives shoppers two different approaches to Nothing's midrange lineup. The Nothing Phone 4a launched in March 2026, followed by the more affordable Nothing Phone 4b in July 2026.

Now that both phones are available, buyers can compare confirmed specifications, features, and pricing rather than relying on early leaks. The differences in performance, cameras, battery capacity, and display also give online accessory retailers two distinct models to plan inventory around.

Nothing Phone 4a vs 4b: Specifications Compared

Both are midrange Android phones, but the confirmed Nothing Phone 4a spec and Nothing Phone 4b spec reveal some meaningful differences.

*Battery capacity varies by market. The Phone 4a has a 5,400mAh battery in India, while the Phone 4b has a 6,000mAh battery in India.

Design

Nothing has built its identity around phones that look different from conventional Android devices, so design remains an important part of both models.

The phones don't share identical dimensions. The Phone 4a measures 163.9 x 77.5 x 8.5mm, while the Phone 4b measures 164.4 x 78.2 x 8.6mm. That matters for consumers, but it's even more important for retailers planning Nothing Phone 4a accessories and Nothing Phone 4b accessories. Cases should be sourced specifically for each model.

Display

The Phone 4a has a 6.8-inch AMOLED display with a 120Hz adaptive refresh rate, while the Phone 4b uses a 6.77-inch Super AMOLED display that also reaches 120Hz. The 4a offers the higher display resolution, giving it an advantage for shoppers who prioritize screen quality.

Because the phones differ in dimensions and display specifications, retailers shouldn't assume a Nothing 4a screen protector will fit the 4b. Model-specific screen protection is the safer inventory choice.

Camera

Camera hardware is another point of separation. The Phone 4a has a triple-camera system, while the Phone 4b uses a dual-camera setup. The 4a also has a 32MP front camera compared with the 4b's 16MP front camera.

Those differences make the 4a the stronger option on paper for shoppers who prioritize camera versatility. Actual image quality still depends on more than megapixels, including sensors, lenses, image processing, and software.

Battery

The Phone 4b has the larger battery of the two, with a 5,200mAh capacity globally compared with 5,080mAh for the Phone 4a. Nothing calls the 4b its longest-lasting phone yet.

The 4a has the advantage in charging speed, supporting 50W fast charging compared with 33W for the 4b. That creates a straightforward tradeoff: the 4b offers more battery capacity, while the 4a can recharge faster.

Nothing Phone 4a vs 4b: Which One Is Better?

There isn't one winner for every buyer, but the differences are much clearer now that both phones are available.

The Phone 4a is the stronger choice for shoppers who prioritize performance, display quality, cameras, and faster charging. Its Snapdragon 7s Gen 4 processor also sits above the Snapdragon 6 Gen 4 used in the 4b.

The Phone 4b makes its case with a lower starting price and larger battery. That positions it as the more budget-conscious choice for buyers who want the Nothing experience without paying for the 4a's upgraded hardware.

Ultimately, the better phone comes down to priorities. The 4a offers more capable hardware, while the 4b focuses more heavily on affordability and battery life.

Nothing Phone 4a vs 4b: How Should Online Sellers Prepare the Accessories?

For online sellers, the Nothing Phone 4a and 4b call for separate accessory planning. Their differences in size, camera layout, and display mean that cases and screen protectors are designed for each model, rather than shared across the range.

That makes model-specific SKUs important from the start. Stocking the right accessories helps avoid fit issues and makes it easier to keep popular products available as demand develops.

A focused range can cover the essentials:

• Cases: Start with everyday styles such as clear, magnetic, and protective cases.
• Screen protectors: Offer protectors made specifically for each model, with the correct dimensions and cutouts.
• Charging accessories: Build around each phone's charging capabilities with compatible chargers and cables.
• Bundles: Pair complementary accessories, such as a case and screen protector, to create a simple add-on purchase.

There is no need to carry every style at launch. Starting with core SKUs gives sellers room to see what customers respond to, then expand into new colours, materials, and designs as demand grows. It keeps the range relevant without committing too much inventory to an untested model.
