🧠 Performance & Processor
The MediaTek Dimensity 6300 chipset is the real engine behind the Realme 15X 5G. Built on the efficient 6 nm process, this SoC delivers a balance of power, 5G connectivity, and battery efficiency. The two high-performance Cortex-A76 cores handle demanding tasks like gaming or editing, while the six Cortex-A55 cores ensure smooth day-to-day multitasking.
Paired with up to 8 GB RAM, the phone also supports Dynamic RAM Expansion (DRE), allowing an additional 8 GB of virtual memory. This makes multitasking snappy—users can switch between apps, games, and browser tabs without lag.
When tested with popular games like BGMI, COD Mobile, and Asphalt 9, the phone maintains consistent frame rates around 55–60 FPS at medium settings. For a mid-range 5G smartphone, that’s impressive performance.
📱 Display – Smooth & Bright Visuals
The Realme 15X 5G flaunts a 6.8-inch IPS LCD display with a 144 Hz refresh rate—a feature rarely seen in this price range. Whether you’re scrolling social media or watching action-packed videos, the ultra-smooth motion makes everything feel seamless.
The panel offers HD+ resolution (1570 × 720), which may not be flagship-level sharp, but color calibration is pleasing with balanced tones and decent brightness. With up to 1200 nits peak brightness, outdoor visibility remains excellent even under sunlight.
The 180 Hz touch sampling rate improves gaming responsiveness, giving users quicker touch feedback during gameplay.
🎨 Design & Build Quality
Realme continues its design-first approach with the 15X 5G. The phone features a sleek gradient finish that changes hues when light hits it from different angles. The rear panel houses a dual-camera module with circular lenses, giving it a premium and symmetrical aesthetic.
Despite weighing over 200 grams, the ergonomics are well-balanced. Rounded edges and a matte texture ensure a comfortable grip. Moreover, its IP69 rating adds durability against water and dust—something rarely found in mid-range smartphones.
Color options like Aqua Blue, Marine Blue, and Maroon Red give buyers a refreshing variety to match their personal style.
📸 Camera – Balanced and Reliable

The main camera captures sharp, detailed photos in daylight with accurate color tones. HDR mode works effectively to preserve highlights and shadows in challenging lighting.
In low-light conditions, the Night Mode enhances brightness and reduces noise effectively, although you might notice minor softening in finer details.
Front Camera
The 16 MP selfie camera offers crisp selfies with good skin-tone reproduction. Beauty AI settings can be customized for natural-looking portraits, and the front sensor also supports portrait bokeh mode and HDR selfies.
Video Performance
Both front and rear cameras record 1080p videos at 30 fps. The electronic image stabilization (EIS) ensures smoother clips, though heavy shakes can still be noticeable. For content creators or vloggers, this camera setup is sufficient for day-to-day shooting.
