Phone or Power Bank? Realme Unveils the Realme P4 Power With a 10,001mAh Battery

Key Highlights

  • Realme P4 Power packs a 10,001mAh silicon-carbon battery
  • Promises 80% battery health even after eight years
  • Supports 80W fast charging and 27W reverse charging
  • Features IP66, IP68, and IP69 durability ratings

Realme has launched the Realme P4 Power, its first smartphone with a 10,001mAh battery. The device focuses on extreme endurance and long-term use. It arrives less than a year after Realme showcased a 10,000mAh prototype, turning that concept into a consumer product.

The phone uses a next-generation silicon-carbon battery. Realme claims it will retain at least 80 percent capacity after eight years. It is rated for 1,650 charge cycles.

What makes the Realme P4 Power different?

The Realme P4 Power aims to remove battery anxiety. On a full charge, it can run BGMI for nearly 12 hours or stream YouTube for over 32 hours. Navigation can last more than 21 hours. Even at 5 percent, users can still make voice calls for almost four hours.

Realme says the massive cell reduces charging frequency. After four years, an average user may complete nearly 400 fewer charge cycles than on a typical phone.

How fast does it charge?

Despite the huge battery, charging stays practical. The phone supports 80W SuperVOOC fast charging. It reaches 50 percent in about 36 minutes. USB PD PPS chargers work up to 55W.

It also supports 27W reverse charging. Realme says it can charge an iPhone 16 Pro to 50 percent in 27 minutes. In daily life, the phone doubles as a power bank.

Is it bulky?

The Realme P4 Power measures 9.08mm thick and weighs 219g. That is only slightly heavier than phones with far smaller batteries. The chassis is built for harsh conditions.

The battery works between -30°C and 56°C. The phone is drop-tested from one meter. It carries IP66, IP68, and IP69 ratings. It survives dust, submersion, and high-pressure hot water.

What about the rest of the hardware?

The phone features a 6.8-inch quad-curved display with 144Hz refresh rate and 1,280 x 2,800 resolution. Peak brightness reaches 6,500 nits.

It runs on the Dimensity 7400 Ultra chipset with a large vapor chamber and graphite cooling. The camera setup includes a 50MP main sensor with OIS, an 8MP ultra-wide camera, and a 16MP front camera.

The Realme P4 Power launches with Android 16 and Realme UI 7. It will receive three years of OS updates and one more year of security patches.

With its 10,001mAh battery, the Realme P4 Power signals a shift toward phones designed for years, not days.
