The Realme P4x 5G is the latest contender to stake a serious claim on the fiercely competitive budget-to-mid-range segment in India. Launched in early December 2025, the P4x is engineered with a singular, compelling value proposition: to deliver extreme battery endurance and sustained, reliable performance—features that historically demanded a much higher price point. It’s a calculated blend of cutting-edge features and strategic cost-saving measures, resulting in a device that commands attention, particularly from power users and mobile gamers on a budget.
This detailed review dissects the Realme P4x 5G, analyzing the effectiveness of its gargantuan battery, the performance stability of its Dimensity 7400 Ultra chipset, the compromises inherent in its camera system, and its highly aggressive price positioning in the Indian market.
Specifications and Design: Aerospace Aesthetics and Core Power
The Realme P4x 5G features a distinctive “Aerospace Design,” giving the phone an appealing, modern, and slightly high-end visual appeal that stands out from the generic plastic backs often seen in this segment. Despite housing a massive battery, the device manages to maintain a respectable thickness of 8.39mm and a weight of 208 grams. It also features an IP64 rating for dust and splash resistance, adding a necessary layer of real-world durability.
The core hardware is robust:
- Processor: The phone is powered by the MediaTek Dimensity 7400 Ultra 5G chipset, built on a 4nm process. This is a crucial element of the P4x’s performance claim, delivering an AnTuTu score of over 780,000—a figure that positions it as one of the fastest chipsets available in its price category.
- Storage and RAM: Available in configurations up to 8GB of LPDDR4X RAM and up to 256GB of UFS 3.1 storage. The inclusion of UFS 3.1 is a significant win for the price, ensuring faster app loading and file transfer speeds than the slower UFS 2.2 standard commonly used by rivals.
- Cooling: To maintain the high performance of the Dimensity 7400 Ultra, Realme has integrated a 5300mm² VC (Vapour Chamber) Frozen Crown Cooling System, designed to ensure thermal stability during prolonged, high-intensity gaming sessions.
Battery Life and Charging: The 7,000mAh Titan
The undisputed headline feature of the Realme P4x 5G is its enormous 7,000mAh “Titan” battery. This capacity is rarely seen in mainstream smartphones and effectively positions the P4x as the “King of Endurance” in the budget segment.
In real-world testing, the 7,000mAh cell truly delivers on its promise. Casual users can expect the phone to last easily two days on a single charge. Even under heavy use—including hours of gaming, video streaming, and continuous mobile data usage—the P4x comfortably provides over 9 hours of screen-on-time, often stretching into a full day and a half. The PC Mark Work 3.0 battery life test confirmed its exceptional longevity, showcasing a usage time of over 17.5 hours.
Recharging this massive battery is handled by 45W wired fast charging. While 45W is fast, the sheer size of the 7,000mAh battery means the charging time is not instant; a 0% to 100% charge takes approximately 90 minutes (1.5 hours). This is a necessary trade-off for the immense capacity. The phone also supports 5W reverse wired charging, allowing it to function as a power bank for small accessories.
Display and Multimedia Experience
The visual experience is delivered by a 6.72-inch Full HD+ LCD display with a resolution of $1080 \times 2400$ pixels. The primary selling point here is the 144Hz refresh rate, a flagship-level specification that ensures buttery-smooth scrolling and high-fidelity visuals in compatible games. The screen also boasts a peak brightness of 1,000 nits, offering decent outdoor visibility (marketed as a “Sunlight Display”).
The main compromise is the use of an LCD panel instead of an AMOLED. While the 144Hz refresh rate is excellent, the LCD panel inherently lacks the deep blacks, rich contrast, and superior outdoor clarity of an AMOLED found on some similarly priced competitors. Audio is handled by dual speakers, enhancing the multimedia and gaming experience, particularly with the 400% Ultra Volume setting that provides great loudness, though sometimes at the cost of clarity.
Camera Quality: Functional, But Not Flawless
The camera system is where the Realme P4x 5G makes its most apparent compromises to meet its aggressive price point. The rear features a dual-camera setup:
- Primary Camera: 50MP AI Main Camera ($f/1.8$) with Phase Detection Autofocus.
- Secondary Camera: A basic 2MP Mono/Depth sensor.
- Front Camera: 8MP selfie camera ($f/2.4$).
In well-lit conditions, the 50MP main sensor captures vibrant, sharp 12.5MP binned photos with good dynamic range. The images are highly social-media friendly, often featuring bright, punchy colors. Video recording supports up to 4K at 30fps, a strong feature in this segment.
However, the camera struggles in challenging conditions: the lack of a dedicated ultrawide sensor limits versatility, and low-light and indoor photos can appear soft and show visible noise when zoomed in. The 8MP front camera is functional for video calls but lacks the detail of higher-resolution selfie shooters. The camera is highly competent for everyday snapshots but is not a segment leader for computational photography.

Gaming Performance and Stability
The Realme P4x 5G is marketed as a “performance champ,” and the Dimensity 7400 Ultra largely backs this claim. The device handles demanding games like BGMI and Call of Duty: Mobile smoothly.
The key performance metric is sustained frame rates. The P4x supports up to 90 FPS gameplay in supported titles. While testing shows that the frame rate may fluctuate and hover between 69-75 FPS under prolonged load, the cooling system effectively prevents the phone from becoming excessively hot (temperature remains below $40^\circ C$), ensuring performance degradation is manageable. The combination of the Dimensity 7400 Ultra, UFS 3.1 storage, and 144Hz display makes the P4x one of the most capable gaming devices at its price point.

Final Verdict: The Endurance and Performance Bargain
The Realme P4x 5G is a brilliant demonstration of focused engineering. It is a phone built for the power user who travels frequently, games heavily, and prioritizes uptime over everything else. While the compromises in the camera and display panel are evident, they are overshadowed by the sheer utility of the 7,000mAh battery and the brute force efficiency of the Dimensity 7400 Ultra. At its launch price, the Realme P4x 5G is the definitive performance and endurance bargain of late 2025.
