The Nothing Phone 4a has the stronger listed chipset, a larger and higher-resolution display, and a more versatile rear-camera setup. The realme 16 lists a much larger battery, faster charging, and a higher-resolution selfie camera. Which is the better buy depends on your priorities and the current price and stock in your market.
Nothing Phone 4a vs realme 16: specs at a glance
The table compares specifications reported by 91mobiles. Prices are snapshots displayed by that source, not guaranteed current offers. The Nothing price shown separately below is from its official UK page, so it is not directly comparable to the India listing.

The Phone 4a has the on-paper display advantage: its 6.78-inch panel is both larger and higher-resolution than the realme 16’s 6.57-inch panel. Both are listed as 120 Hz flexible AMOLED displays, so the main specification difference is screen size and pixel count rather than refresh rate or panel type. Gadgets 360 also reports the same screen sizes and resolutions.

Which is faster: Snapdragon 7s Gen 4 or Dimensity 6400 Turbo?
The listed chipset comparison favors the Phone 4a. 91mobiles reports an AnTuTu score of 1,176,492 for the Snapdragon 7s Gen 4 phone and 611,679 for the Dimensity 6400 Turbo phone. These are results reported on that comparison page, not an independent test conducted for this article. Benchmark scores can vary with test conditions and software, so they indicate an on-paper performance gap rather than a guarantee of how every app or game will feel.
How do their cameras differ?
The rear camera hardware makes the clearest distinction. The Phone 4a is listed with a main camera, a periscope telephoto camera offering up to 3.5× optical zoom, and an ultrawide camera. That gives it more stated focal-length flexibility for distant subjects and wide scenes. The realme 16 is listed with a 50 MP main camera and a 2 MP monochrome camera.
For selfies, the realme 16 lists a 50 MP front camera compared with 32 MP on the Phone 4a. More megapixels do not by themselves establish better image quality, and the available comparisons do not provide controlled head-to-head camera samples. Treat the specifications as a guide to hardware and camera options, not a verdict on the photos each phone produces.
Does the realme 16 last longer on a charge?
The realme 16 has the larger listed battery at 7,000 mAh, compared with 5,400 mAh for the Phone 4a, and its listed charging rate is 60 W rather than 50 W. However, 91mobiles’ PCMark battery results are close: 14 hours 38 minutes for the realme 16 and 14 hours 42 minutes for the Phone 4a. Battery capacity and a benchmark result do not guarantee an individual user’s runtime; display settings, signal strength, apps, and usage all matter.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What software support is listed?
91mobiles lists Android 16 and three years of OS updates for both phones. It lists six years of security updates for the Phone 4a and four years for the realme 16. These are secondary-source support figures, so confirm the policy for your exact regional model on the manufacturers’ official support pages before treating the periods as a definitive promise.
What is the price difference?
At the time 91mobiles was accessed, its page showed the realme 16 at ₹35,499 on Amazon. It marked the Phone 4a unavailable in stores, while a separate page header showed ₹34,999 and out of stock. Those India figures are unstable snapshots, and they do not establish a reliable current price difference when one phone is out of stock.
Nothing’s official UK page displayed £379 for the Phone 4a with 8 GB RAM and 128 GB storage. That is a UK price for a specific configuration; it should not be compared as though it were an India offer. Check the price for the same RAM and storage configuration in your own market, along with stock, seller, and warranty terms.

- You want the larger, higher-resolution display.
- You value rear-camera flexibility, especially a periscope camera with up to 3.5× optical zoom and an ultrawide camera.

Choose the realme 16 if
- You prioritize the larger listed battery and 60 W charging.
- You want a higher-resolution front camera on the specification sheet.
