At its highly anticipated 828 Fan Festival in China, Realme introduced two groundbreaking concept smartphones that highlight the brand’s focus on innovation and user experience. The first device is a concept smartphone featuring an enormous 15,000mAh battery, capable of lasting up to six days of standard usage on a single charge. Realme claims the phone can deliver 50 hours of continuous video playback, 30 hours of gaming, 18 hours of video recording, and up to three months of standby time in flight mode. Additionally, it doubles as a portable power station, allowing users to charge other smartphones and wearables via reverse wired charging.
The handset, reportedly carrying the model number PKP110, is tipped to feature a 6.7-inch display, run Android 15-based Realme UI 6.0, and be powered by a MediaTek Dimensity 7300 chipset paired with 12GB RAM (expandable by an additional 12GB virtually) and 256GB storage. Leaks also suggest the presence of a dual rear camera system and a silver colorway with bold 15,000mAh branding on its rear panel.
The second concept device, dubbed the Realme Chill Fan Phone, introduces a unique approach to thermal management. It is designed with integrated cooling fans that Realme says can lower the phone’s temperature by up to 6 degrees Celsius during heavy gaming sessions. Teasers show a vent grille on the side for air circulation, giving the impression of a “mini built-in AC.” The phone resembles the Realme GT 7T in design and is showcased in a bold blue color variant.
Both phones are strictly concept models and may not see commercial release anytime soon. However, they demonstrate Realme’s vision for future smartphones – combining massive endurance batteries with advanced cooling technologies for gamers and power users alike.
