Realme P4 Power: the world’s first smartphone with a 10,001 mAh battery, available for $260.

Realme P4 Power – a smartphone built for “battery” power

What’s new

Battery

- 10 001 mAh silicon‑carbon battery designed for 1,650 charge cycles.
- After eight years it will retain ≥80 % of its capacity and can endure 150–200 cycles more than ordinary batteries.

Autonomy

Charge‑up frequency

In four years a user will have charged the phone roughly 392 cycles less than with a standard model.

Operating system and updates

- Android 16 + Realme UI 7.
- Platform support: 3 years of OS updates, 4 years of security patches.
- By the time support ends, the battery will still be nearly new, but the Dimensity 7400 Ultra chip will already be obsolete.

Cooling system

The chip is protected by a vapor‑cooled chamber (4 613 mm²) plus a graphite plate (13 743 mm²).

Fast charging

Physical parameters

- Thickness: 9.08 mm
- Weight: 219 g
- Extreme temperature tolerance: –30 °C … 56 °C
- Drop resistance (1 m), compression, and IP protection: IP66/IP68/IP69
- Water resistance: submersible to 2 m; withstands hot water up to 85 °C and cold water down to 0 °C.

Display

- 6.8‑inch AMOLED
- Resolution: 2800 × 1280 pixels
- Refresh rate: 144 Hz
- Peak brightness: 6500 cd/m²
- Protection: Corning Gorilla Glass (details not specified)

Bottom line

The Realme P4 Power is a smartphone aimed at the “battery‑centric” market. Its hallmark is an enormous battery capacity and long lifespan, allowing users to charge less frequently. Other than that it is almost identical to the base P4: same display, chipset, and design. OS updates are limited to three years, but this isn’t critical for users who value reliable autonomy in any conditions.
