The modern mid-range smartphone market is fiercely competitive, with brands striving to strike the perfect balance between performance, endurance, and design. Enter the Realme P4x—a device that makes a bold statement with its massive 7,000mAh battery and the capable MediaTek Dimensity 7400 Ultra 5G chipset. Aimed squarely at power users who value long screen time and smooth gaming, the P4x sets out to redefine what “all-day performance” truly means.
In an era where many smartphones struggle to survive a full day, the P4x almost dares you to leave your charger at home. But with rising smartphone costs and increasing premiumisation across categories, the real question remains—can a sub-Rs 20,000 smartphone truly deliver enough value to become your dependable daily driver? After spending quality time with the device, here’s the verdict.
Design & Display
Realme has clearly invested in the visual appeal of the P4x. The phone sports what the company calls an “Aerospace Design,” featuring an anodised, metal-grain textured back paired with a right-angled middle frame. The result is a striking, industrial look that feels far more premium than typical plastic-backed phones in this segment. The design might even remind you of a flagship that costs over four times its price.
At 208 grams and 8.39mm thick, the P4x is not lightweight, but that’s an understandable trade-off given the colossal battery inside. The Matte Silver variant, in particular, feels excellent in hand thanks to its glass-like texture. The addition of an IP64 rating for dust and water resistance is a welcome bonus at this price point.
On the front, the phone features a 6.72-inch Full HD+ LCD display with a 144Hz refresh rate. While it’s not an AMOLED panel, the high refresh rate ensures smooth scrolling and fluid animations. With a peak brightness of 1000 nits, Realme’s “Sunlight Display” branding holds up well in real-world outdoor usage, even under harsh lighting.
Audio duties are handled by dual stereo speakers with a 400% volume boost mode. Calls are loud and easily audible in noisy environments like metro stations or malls. While loudness is impressive, audio clarity at maximum volume could be better—but it’s not a dealbreaker.
Battery Life: The Undisputed Star
If there’s one feature that truly defines the Realme P4x, it’s the 7,000mAh battery. This monstrous cell easily delivers multi-day endurance for moderate users. During testing, the phone comfortably lasted from 8 AM to 8 AM the next day with heavy usage, including gaming, video streaming, and camera testing.
Charging is handled by a 45W fast charger included in the box, which powers the phone from 1% to 100% in roughly 90 minutes. Considering the battery size, this is a respectable charging speed.
Performance
Under the hood, the Realme P4x runs on the MediaTek Dimensity 7400 Ultra 5G chipset, placing it firmly in the upper mid-range performance bracket. With up to 8GB of RAM and UFS 3.1 storage, everyday multitasking is smooth and responsive.
In real-world use, the phone handled 15+ background apps without any stutter, and gaming performance was equally solid. Titles like BGMI and Call of Duty ran at a stable 90 FPS, aided by a large vapour chamber and a steel cooling plate that effectively controls heat during prolonged sessions.
Despite the 144Hz display, most games currently max out at 90FPS—but even then, the experience remains fast, fluid, and enjoyable.
Camera Performance & AI Features
The Realme P4x features a 50MP primary rear camera paired with a 2MP secondary sensor, while the front houses an 8MP selfie camera. The main camera captures sharp, detailed images and supports 4K video recording with stable performance and no noticeable overheating.
Where Realme places major emphasis is on its AI-powered tools, bundled under the “AI Treasure Box.” This includes:
AI Eraser – genuinely useful for removing unwanted objects.
AI Motion Deblur – helpful in specific scenarios.
AI Glare Remover – works occasionally but less consistent.
For everyday photography, the camera performs reliably within its price segment, making it suitable for social media, casual portraits, and video recording.
Software & User Experience
The P4x runs on Realme UI 6.0, which now comes integrated with several practical AI utilities. Standout features include:
AI Scanner – converts printed notes into searchable PDFs.
AI Recording – generates summaries from voice recordings.
Circle to Search – quick visual lookup for anything on-screen.
Rather than overwhelming users with gimmicks, Realme has focused on productivity-oriented AI tools, and that’s a strategy that clearly works.
Price & Final Verdict
The Realme P4x is available in three variants:
6GB + 128GB
8GB + 128GB
8GB + 256GB
It starts at Rs 15,999, and with bank offers and discounts, it often drops even lower—making it extremely competitive in the under-Rs 20,000 category.
✅ Final Thoughts
The Realme P4x is a well-rounded smartphone that delivers where it matters most—battery life, solid performance, reliable cameras, and a premium-inspired design. It may not dominate any single category outright (except battery), but it also doesn’t suffer from any glaring weaknesses.
If you’re looking for a safe, stable, and dependable smartphone under Rs 20,000 that excels in endurance and everyday usability, the Realme P4x is a strong contender and an easy recommendation.
