Realme P4 Power Camera Test: Is the 50MP Sony IMX882 Good Enough?
I started TrendingAlone to make tech news simple and useful. Every day, I cover the latest smartphone launches, gadgets, and digital updates - but instead of just listing specs, I explain what they actually mean for real users. With over 10 years in tech journalism, I focus on the brands people in India follow most — Samsung, OnePlus, iPhone, Xiaomi, Motorola, and more. My stories are written to help readers quickly understand if a new device or update is worth their time.
Realme’s P4 Power arrives in India as the country’s first commercial smartphone packing a 10,001mAh battery, effectively shifting the mid-range value equation from raw performance to multi-day endurance.
The engineering centerpiece of the P4 Power is its high-density silicon-carbon anode cell. By replacing traditional graphite structures with silicon composites, Realme managed to double standard flagship battery capacities without ballooning the device into a ruggedized industrial brick.

| [ MediaTek Dimensity 7400 Ultra ] <-------------+ |

| [ LPDDR4X RAM + UFS 3.1 ] |
| |
| [ 10,001mAh Si/C Titan Cell ] ---> 80W Input / 27W Reverse Wired |
+-------------------------------------------------------------------+
The device pairs this cell with 80W wired charging and 27W reverse wired charging. The reverse charging capability outputs enough juice over USB Power Delivery to comfortably power accessories, wireless earbuds, or top up a secondary device in an emergency.
However, prospective owners should understand the thermal physics of large-capacity charging: replenishing a 10,001mAh pack at 80W requires strict thermal mitigation profiles. Charging speeds will step down aggressively after initial peak bursts to preserve internal chemistry, resulting in longer total plug-in durations than standard 5,000mAh devices boasting identical wattage ratings.
The P4 Power is built around a 6.78-inch 1.5K quad-curved AMOLED display operating at up to 144Hz, capable of hitting a claimed 6,500 nits peak brightness.
| Hardware Component | Realme P4 Power Specification | Real-World Impact & Limitation |
| Battery & Charging | 10,001mAh Si/C; 80W In / 27W Out | True 2- to 3-day battery life; prolonged full recharge times. |
| SoC & Memory | Dimensity 7400 Ultra; LPDDR4X; UFS 3.1 | Adequate daily speed, but LPDDR4X memory bandwidth bottlenecks heavy multitasking. |
| Display Panel | 6.78-inch 1.5K 144Hz Quad-Curve AMOLED | High fluid rendering; non-LTPO panel draws steady power at elevated refresh rates. |
| Camera Hardware | 50MP Sony IMX882 (OIS) + 8MP Ultra-wide | Reliable main sensor; lacks telephoto zoom and advanced secondary optics. |
| Durability Rating | Triple IP66 / IP68 / IP69 Certification | Complete protection against high-pressure washdowns, submersion, and dust. |
The most glaring compromise sits in the memory bus. While competitors around the Rs 30,000 threshold deploy faster LPDDR5X RAM, the P4 Power relies on older LPDDR4X memory. For routine web browsing and video streaming, the difference is negligible; for prolonged high-framerate gaming or heavy background app retention, the memory architecture will show its ceiling earlier over the device's lifecycle.
Realme backs the hardware with an impressive endurance claim: the battery is rated to retain 80% of its operational health after 1,650 charge cycles—equivalent to roughly four years of typical use—alongside an 8-year longevity guarantee.
The paradox lies in the software commitment:
OS Platform Updates: 3 years (Android 16 through Android 19).
Security Maintenance: 4 years (ending in 2030).
While 3+4 years is standard for mid-tier Android handsets, it falls short of the physical longevity the hardware is engineered to achieve. Users keeping the device for its durable battery and IP66/IP68/IP69 chassis will find the software lifecycle expiring long before the silicon-carbon cell reaches its degradation threshold.
The chassis achieves rare industrial durability with simultaneous IP66, IP68, and IP69 ratings, making it resistant not just to static water immersion, but also to high-temperature, high-pressure water jets.
To fit the battery and maintain the Rs 27,999 price tag, Realme streamlined the camera system.
The Realme P4 Power is purpose-built for field professionals, extreme travelers, delivery gig workers, and mobile power users who view daily charging as an operational liability. For users who prioritize camera versatility or pure esports-grade processing, balanced alternatives with smaller batteries exist. But for those whose primary metric is uninterrupted screen time, the P4 Power establishes a battery benchmark that competitors will struggle to match without bulk
