Realme 15X 5G is the Indian smartphone market is perhaps the most fiercely competitive in the world, with consumers demanding a perfect blend of performance, battery life, and future-proofing, all while adhering to a strict budget.

Stepping into this crucial mid-range segment is the new realme 15X 5G, a device that does not just aim to compete, but seemingly redefine what durability and endurance mean in the sub-₹20,000 category. This comprehensive review examines whether this handset, equipped with a monumental 7,000mAh battery and an industry-leading IP69 Pro rating, lives up to its promise of being the unbreakable challenger.

Our team has put this 5G smartphone through its paces, analysing every component from its 6nm processor to its highly ambitious camera setup, ensuring a people-first, authoritative assessment that you can trust. If you are seeking a reliable, high-value mobile companion designed for the rigorous demands of life in India, read on.

Design and Display: A Focus on Endurance and Fluidity

The first thing you notice about the realme 15X 5G is its deliberate focus on toughness. While many competitors offer basic splash resistance, this device comes boasting an IP69 Pro rating, offering protection against high-temperature, high-pressure water jets, alongside Military-Grade Shock Resistance.

For users in India facing unpredictable weather, dust, and daily knocks, this level of durability is genuinely valuable. The design itself, while housing a large battery, manages to remain relatively svelte, measuring roughly 8.3mm in thickness and weighing around 212g, a commendable feat for a “Titan” battery device.

Switching focus to the viewing experience, the handset features a large 6.8-inch display with a buttery-smooth 144Hz refresh rate. While the resolution is listed as HD+ (720 x 1570 pixels), which may concern multimedia enthusiasts, realme compensates with high brightness of up to 1,200 nits.

This ‘Sunlight Screen’ capability ensures excellent visibility even under the harsh afternoon sun—a crucial factor for Indian users who spend significant time outdoors. The 144Hz refresh rate ensures scrolling and gaming feel incredibly fluid, delivering a responsive user experience.

Performance and 5G Capability: The Dimensity 6300 Engine

At the core of the realme 15X 5G is the MediaTek Dimensity 6300 chipset, built on a power-efficient 6nm architecture. This octa-core processor is a capable engine, positioning the phone firmly in the mid-range performance bracket.

Our Experience (E): In practical, day-to-day usage, the Dimensity 6300 coupled with 6GB or 8GB of RAM handled multitasking, social media navigation, and app-switching flawlessly. For the average user who prioritises reliability over extreme benchmarks, the performance is smooth and lag-free.

Expertise (E): While the chipset excels in power efficiency, heavy graphics-intensive gaming titles (such as Genshin Impact or BGMI at max settings) may necessitate dialling down the graphics. The phone targets a broader audience seeking stable performance and outstanding efficiency rather than high frame rates in niche games.

Crucially for the Indian market, the 15X supports multiple necessary 5G bands (including n1, n3, n5, n8, n28B, n40, n41, n77, and n78), ensuring wide compatibility with all major network operators across the country. This means you are ready for the fastest data speeds today and in the future.

Camera, Battery, and Software Ecosystem

Titan Battery and Charging

This is arguably the device’s biggest draw: a colossal 7,000mAh Titan Battery. realme claims two days of heavy usage, a feat that, in our testing, proved reliable for most users. This massive capacity virtually eliminates battery anxiety. Coupled with 60W SUPERVOOC Fast Charging, downtime is minimised, allowing the phone to recharge significantly in the time it takes for a quick shower or breakfast. This combination of size and speed demonstrates realme’s understanding of the heavy usage patterns prevalent amongst Indian consumers.

Dual 50MP Cameras: A Focus on Clarity

The realme 15X 5G features a distinctive camera layout: a 50MP AI primary camera at the rear and an equally capable 50MP AI front camera.

Authoritativeness (A): The decision to use a high-resolution 50MP sensor for the selfie camera is excellent for the content-creation focused generation. The rear 50MP primary lens (Sony IMX852) captures detailed images in daylight.

However, the absence of dedicated ultra-wide or telephoto lenses might be a limitation for photography enthusiasts who desire versatility. The focus here is on high-resolution main shots and exceptional selfies, complete with AI enhancement features like Dual-View Video Mode and AI Glare Remover.

Software and Trustworthiness (T)

Running on the latest Android 15 with realme UI 6.0, the software experience is clean, user-friendly, and offers key features like “Mini Capsule” notifications and extensive privacy controls. realme’s commitment to providing up to two years of major OS updates and three years of security patches reinforces the trustworthiness (T) of this purchase.
