Realme Unveils Prototype Phone With Massive 15,000 mAh Battery

Realme is making waves ahead of its 828 Fan Festival with a major announcement: the company has revealed a prototype smartphone equipped with a 15,000 mAh battery, surpassing even some portable power banks. This comes after last week’s teaser, where Realme hinted at a device featuring a battery capacity exceeding 10,000 mAh.

According to the official teaser shared on Realme’s social media, this upcoming phone promises impressive endurance. The company claims the device can deliver up to 18.45 hours of continuous video recording, 50 hours of video playback, and an astonishing 5.18 days of regular usage on a single charge—making it one of the longest-lasting smartphones in the market.

In addition to the massive battery, Realme has also teased a built-in cooling fan. This unique feature is said to reduce the phone’s temperature by up to 6°C, addressing one of the main challenges of high-capacity smartphones—overheating during intensive tasks like gaming, streaming, or heavy multitasking.

While Realme has not yet revealed other specifications or the official design of the phone, this prototype hints at a device designed for power users who prioritize battery life. With this development, Realme is positioning itself as a brand focused on pushing the limits of smartphone endurance and performance.

The 828 Fan Festival is expected to provide more details about this futuristic phone, and tech enthusiasts are eagerly waiting to see whether this massive battery will become a reality in a commercial device.
