Realme P4 Power Review: The Smartphone That Redefines Battery Expectations

The Realme P4 Power represents a significant leap in smartphone battery technology, leveraging Silicon-Carbon (Si/C) chemistry to deliver unprecedented energy density. With its 10,001mAh capacity, this device doesn't just extend usage time—it fundamentally challenges how we think about power management in mobile devices.

Battery Technology Breakthrough

Si/C batteries offer approximately 30% higher energy density than traditional lithium-ion cells, enabling capacities previously seen only in tablets. What makes the P4 Power exceptional is how Realme implemented this technology:

• Longevity claims: Realme states the battery retains 80% capacity after 8 years of normal use, addressing degradation concerns common in high-capacity batteries
• Efficient charging: The 80W SuperVOOC system replenishes 50% charge (equivalent to a full charge for most smartphones) in 36 minutes
• Power sharing: 27W reverse charging turns the device into a power bank for other gadgets

Despite the massive battery, the phone maintains reasonable dimensions at 9.1mm thickness and 219g weight. For perspective, this is only slightly heavier than many 5,000mAh smartphones, demonstrating how Si/C technology minimizes bulk.

Flagship Performance Beyond the Battery

Realme avoided compromises elsewhere, blending hardware from its P4 and P4 Pro lines:

• Display: The 6.8-inch AMOLED panel features a 144Hz refresh rate, HDR10+ support, and extraordinary brightness levels—6500 nits peak for sunlight visibility
• Processing: MediaTek's Dimensity 7400 Ultra (4nm) chipset delivers efficient performance with its octa-core CPU configuration
• Durability: IP69 certification ensures resistance against high-pressure water jets and dust ingress, while MIL-STD-810H compliance adds shock resistance
• Software: Android 16 with Realme UI 7.0 includes a commitment to three major OS updates

Ecosystem Context

This device strengthens Realme's position in the BBK Electronics ecosystem alongside OnePlus and Oppo, collectively pushing battery and charging innovations. The P4 Power demonstrates how manufacturers are overcoming historical trade-offs between battery size and device portability.

For consumers, the implications are significant:

• Heavy users gain 2-3 days of active use per charge
• Reduced charging frequency extends long-term device value
• Ecosystem compatibility includes shared charging standards across BBK brands

The camera system adopts a practical approach with a 50MP OIS-stabilized main sensor and 8MP ultra-wide lens—sufficient for documentation rather than competing with imaging-focused flagships.

Realme includes essential accessories in most markets, notably the 80W charger in the Indian variant. The bundled silicone case acknowledges the device's thickness while maintaining pocketability.

By achieving tablet-level battery capacity in a phone form factor, the P4 Power establishes a new benchmark for mobile endurance. As Si/C technology matures, it could accelerate the decline of power banks and reshape how manufacturers approach device design. For travelers, outdoor professionals, or anyone prioritizing uptime over slim aesthetics, this device delivers a compelling solution.
