realme Unveils 15000mAh Battery and Built-In Cooling Phone at Global Fan Festival 2025

realme just made a bold statement at its 7th anniversary celebration, introducing two breakthrough smartphone innovations designed for heavy users and mobile gamers alike.

Held during the 2025 Global Fan Festival, the brand revealed its largest smartphone battery to date and an experimental cooling concept phone, drawing excitement from fans around the world.

A Record-Breaking 15000mAh Smartphone Battery

realme’s latest tech leap features a massive 15000mAh battery, the biggest ever in a smartphone. Built with full-silicon anode material, this battery offers unmatched energy density, making it possible to use your device for up to five days on a single charge. That translates to up to 50 hours of video playback and 18 hours of non-stop video recording, eliminating the anxiety of running out of juice mid-content creation or gaming session.

Introducing the Chill Fan Phone with Built-In Cooling

In another first, realme debuted its Chill Fan Phone, a concept device featuring a built-in cooling system that works like an “AC inside your phone.” Using thermoelectric technology, it can reduce core temperatures by up to 6°C. This means more stable performance during high-intensity tasks like gaming on Honkai: Star Rail or Genshin Impact, without overheating or lag.

These innovations align with realme’s mission to support the needs of young users, especially gamers, streamers, and content creators, by addressing two of the most common pain points in smartphones today: battery life and heat management.
