Forget daily charging – this upcoming phone’s 10,001mAh battery helps it last a week, but it’s still lighter than an iPhone 17 Pro Max

• The Realme P4 Power has a 10,001mAh battery
• Despite that huge capacity, it weighs just 219g
• It’s launching in India on January 29, with a global launch to be confirmed

We seem to be in the middle of a battery capacity revolution, as following on from the likes of the 7,300mAh OnePlus 15 leaping ahead of the 5,000mAh smartphone standard last year, now Realme has teased a phone with a 10,001mAh battery.

Dubbed the Realme P4 Power, this phone is launching on January 29, but the company has already shared a lot of details about it, including that the phone can apparently manage 185.7 hours of music playback, 21.3 hours of navigation, 32.5 hours of YouTube, or 72.3 hours of call time on a single charge.
