SaralnamaOn 28 Aug 2025, Realme showcased two innovative smartphones at its 828 Fan Festival in China. The first is a concept phone with a massive 15,000mAh battery, which is 42% slimmer and 68% lighter than traditional power banks of similar capacity. It features a 6.7-inch OLED display, MediaTek Dimensity 7300 processor, 12GB RAM, 256GB storage, and supports 80W fast charging. This phone can deliver up to 50 hours of video playback, 18.45 hours of video recording, 30 hours of gaming, and over 5 days of typical use on a single charge. The battery is only 6.48mm thick due to a new all-silicon anode design with high energy density. The second device is the world’s first "AC" smartphone with a built-in cooling fan that lowers the core temperature by up to 6.2°C and changes color as it cools. While the 15,000mAh phone is still a concept, Realme may launch a 10,000mAh battery phone commercially by 2026. The production timeline for the cooling fan phone is not yet clear.
