The Realme P4 Power pushes smartphone battery technology to new limits with its massive 10,001mAh silicon-carbon battery. This phablet-sized device combines exceptional endurance with 80W SuperVOOC fast charging, delivering 50% charge in just 36 minutes. Realme promises the battery will retain 80% capacity after 8 years of normal use.

Despite its tablet-like battery capacity, the P4 Power maintains reasonable dimensions at 162.3x76.2x9.1mm and 219g weight. The device features a 6.8-inch AMOLED display with 144Hz refresh rate, HDR10+ support, and peak brightness of 6500 nits. Under the hood, it runs on a Mediatek Dimensity 7400 Ultra chipset with up to 12GB RAM and UFS 3.1 storage.

The camera system includes a 50MP main sensor with OIS and an 8MP ultra-wide lens, while the 16MP front camera handles selfies. Additional features include an under-display fingerprint reader, stereo speakers, and 27W reverse wired charging capability. The phone runs Android 16 with Realme UI 7.0 and promises three major Android upgrades. With its combination of massive battery capacity, fast charging, and premium display, the P4 Power represents Realme's most ambitious battery technology implementation to date.
