At its 828 Fan Festival in China, Realme introduced two new concept smartphones, highlighting innovations in battery technology and cooling systems. These devices are intended to showcase the company’s research and development capabilities and are not planned for commercial release.
15,000mAh Concept Phone
The first concept device features a 15,000mAh battery, advertised to deliver up to five days of use on a single charge. The battery is based on a 100% silicon anode design, which Realme claims offers four times the silicon content of conventional silicon-carbon batteries. It achieves an energy density of 1,200 Wh/L, enabling extended usage while maintaining a device thickness of 8.89mm. The battery itself measures 6.48mm and supports reverse charging, allowing the phone to function as a power bank.
Realme states that the device can provide:
- Over 50 hours of video playback
- Over 18 hours of video recording
- Up to 30 hours of gaming
To achieve this, Realme adopted solid electrolytes, optimized the battery packaging, and reengineered motherboard components.
Though full specifications have not been officially confirmed, posts on Weibo indicate the phone is equipped with a MediaTek Dimensity 7300 chipset, 12GB RAM, 256GB storage, and a 6.7-inch display. It runs Realme UI 6.0 based on Android 15.

Chill Fan Concept Phone
The second concept, referred to as the Realme Chill Fan Phone, incorporates three forms of cooling:
- A 7,700mm² vapor chamber
- An integrated spinning fan
- A thermoelectric cooling module
Combined, these systems can reduce the device’s internal temperature by up to 6°C, helping maintain performance during gaming sessions. Realme claims the phone can sustain maximum frame rates in over 20 popular gaming titles.
Design-wise, the Chill Fan Phone resembles the Realme GT7 series and features the brand’s IceSense Ultra back panel, which changes color from white to blue as the device cools.
