After teasing a phone with a battery bigger than 10,000mAh, realme has confirmed that it will introduce the world’s largest battery phone with, 15000mAh battery and AC-inspired smartphone cooling system tomorrow, August 27th.

The company says that the 15000mAh battery phone will offer up to 18.45 hours of video shooting on a single charge or up to 50 hours of video playback on a single charge and a single charge will offer up to 5.18 days of use.
