The sub-Rs 40,000 smartphone segment in India has intensified with the launch of the Realme 16 5G.

The device enters a competitive space already occupied by the Nothing Phone 4a and Poco X8 Pro, three phones that pack 5G support, AMOLED displays, and 50MP primary cameras.

While they share similar fundamentals, each device targets a different kind of user, battery-focused buyers, performance seekers, and design enthusiasts.

Price and variants: Close competition across the board

The Realme 16 5G starts at Rs 31,999 for the 8GB + 128GB variant and goes up to Rs 36,999 for the 12GB + 256GB model.

The Nothing Phone 4a is similarly priced, beginning at Rs 31,999 and reaching Rs 37,999 for its top-end variant.

Meanwhile, the Poco X8 Pro starts slightly higher at Rs 32,999 and goes up to Rs 35,999.

Across the board, pricing remains tightly packed, making specifications and features the key differentiators.

Display, performance and battery: Where the real differences lie

All three smartphones feature AMOLED panels with 120Hz refresh rates, but brightness and panel quality vary slightly. The Nothing Phone 4a leads with up to 4,500 nits peak brightness, followed closely by the Realme 16 5G at 4,200 nits.

Performance is where the biggest gap appears.

    • Poco X8 Pro is powered by the Dimensity 8500 Ultra chipset, making it the most performance-focused device.

However, Poco counters with 100W fast charging and 27W reverse charging, fastest in the segment.

Camera, design and durability: Unique strengths for each

Camera setups vary notably across the trio.

    • Nothing Phone 4a stands out with a triple camera system, including a periscope lens. 

    • Poco X8 Pro offers a reliable Sony IMX882 sensor with ultrawide support. 

    • Realme 16 5G keeps it simple with a dual setup but adds a unique “selfie mirror” feature.
