Realme promises days of battery from its 10,001mAh phone

After teasing 10,000mAh and 15,000mAh concept devices, Realme is ready to make those big batteries reality with the P4 Power, which launches in India on January 29th with a 10,001mAh capacity.

Realme says the P4 Power will last for three and a half days of light use, which I can believe — I got between two and three days’ battery with the 7,500mAh Oppo Find X9 Pro. Maybe more impressively, the P4 Power supports 27W reverse charging, fast enough that this could double as a power bank for some other devices.

We’ve seen bigger batteries, but not often in phones this size — the P4 Power only weighs 218g, and looks fairly slim, thanks to using a silicon-carbon battery. It might not quite beat the 216g, 8mm-thick Honor Power 2, which has a fractionally larger 10,080mAh battery, but that’s only available in China — an India release means the P4 Power will be much easier for the rest of us to get hold of.
