Realme has once again pushed the boundaries of smartphone innovation by showcasing a concept device with a record-breaking 15,000mAh battery, promising up to four days of usage on a single charge. Despite the colossal power unit, the phone measures just 8.89mm thick and also supports reverse charging, allowing it to double up as a power bank.
Realme’s Next Leap in Battery Tech
Earlier this year, the company demonstrated a 10,000mAh concept phone, but the new prototype goes even further, marking Realme’s boldest step in battery-first smartphone design. While many brands have been experimenting with 7,000mAh and 8,000mAh batteries in India, Realme is positioning itself at the forefront of long-lasting power solutions.
The new 15,000mAh concept phone retains a design language similar to its predecessor, but introduces a revised dual-camera setup, now housed in two horizontally stacked cutouts.
