Realme is making a bold statement in the smartphone industry with the introduction of the P4 Power, a phone that ditches the industry-standard 5,000mAh battery in favor of a massive 10,001mAh “Titan” battery. After unveiling a 10,000mAh concept phone last year, the company has now moved from prototype to production, bringing this ambitious battery capacity to real consumers.
What Makes This Battery Revolutionary
The Realme P4 Power’s standout feature is its unprecedented 10,001mAh Titan battery, which the company claims can deliver up to a week of battery life on a single charge. For users accustomed to daily charging—or even carrying power banks—this represents a significant shift in smartphone usability.
The battery employs silicon anode technology, a high-energy-density solution that stores more power than traditional graphite-based lithium-ion batteries. This advanced engineering allows the P4 Power to achieve its massive capacity while remaining relatively lightweight at just 219 grams, comparable to the Samsung Galaxy S25 Ultra.
Real-World Battery Performance
Real-world usage estimates suggest the phone can deliver:
- Two to three days of heavy use on a single charge
- Up to a full week for lighter users
- 185.7 hours of music playback
- 72.3 hours of call time
- 32.5 hours of YouTube streaming
- 21.3 hours of navigation
According to Realme, the phone will manage approximately three and a half days of light use.
Additional Features and Durability
Beyond battery capacity, the P4 Power supports 80W fast charging and 27W reverse charging, allowing it to serve as a power bank for other devices. The phone also features military-grade shock protection, ensuring durability even with such a large battery.
Realme promises that battery health will remain above 80% for up to eight years, addressing long-term wear concerns. The device is equipped with advanced safety technology to maintain stable performance throughout its lifespan.
Specifications and Availability
The P4 Power features a MediaTek Dimensity 7400 Ultra 5G chipset, a 50MP main camera, and a 144Hz display with 6,500 nits peak brightness. The phone is launching in India on January 29, with plans for global expansion still being finalized.
Realme isn’t alone in this battery revolution. HONOR recently launched the Power 2 with a slightly larger 10,080mAh battery, signaling that five-digit battery capacities are now practical for mass-market devices rather than laboratory concepts.
