Realme has unveiled a concept phone with a massive 15,000mAh silicon-anode battery in a slim 8.89mm design — triple the capacity of the Galaxy S25 Ultra. The phone promises up to five days of use, 50 hours of video, or even powering devices like drones via reverse charging.
However, the battery’s 100% silicon composition makes it highly prone to swelling and degradation, meaning a commercial launch is unlikely. Realme instead may focus on its more feasible 10,000mAh concept phone, which is reportedly ready for production.
