New Delhi, August 28, 2025 – realme, the most popular smartphone brand among Indian youth, today marked its 7th anniversary with the unveiling of two groundbreaking innovations at the realme 828 Fan Festival: the 15000mAh Ultra-High-Density Battery Phone and the realme Chill Fan Phone. These prototype concepts, inspired by the everyday challenges of young users across markets, are designed to eliminate two of the biggest smartphone concerns—battery anxiety and overheating during intense use.
15000mAh Ultra-High-Density Battery Phone
The 15000mAh battery concept represents a quantum leap in smartphone power technology. Built with 100% full silicon anode technology, it achieves an industry-first 1200 Wh/L energy density, delivering unmatched endurance while maintaining a remarkably slim 8.9mm profile through advanced lamination and solid-electrolyte technology.
For users, this translates into extraordinary performance metrics:
- Up to 4-5 days of typical usage on a single charge
- 18+ hours of continuous video recording for content creators
- 50+ hours of uninterrupted video playback for entertainment enthusiasts
- Up to 30 hours of intensive gaming sessions
- Reverse charging capability, allowing the device to function as a power bank for other devices
The prototype features a 6.7-inch OLED display, MediaTek Dimensity 7300 chipset, 12GB RAM, 256GB storage, and 80W SuperVOOC fast charging, all running on Android 15 with realme UI 6.0.
From long commutes and travel to non-stop streaming and marathon gaming, this battery ensures users stay powered without constant recharging anxiety.
realme Chill Fan Phone
The realme Chill Fan Phone introduces the industry’s first smartphone with an integrated miniature internal fan featuring thermoelectric cooling (TEC) technology—previously seen only in external cooling accessories. By incorporating this advanced system directly into the smartphone architecture, realme makes professional-grade thermal management accessible to users everywhere.
This revolutionary cooling innovation reduces core device temperature by up to 6°C, ensuring sustained peak CPU/GPU performance and steady frame rates during the most demanding scenarios. The system maintains smooth performance for 20+ popular high-graphic titles such as Genshin Impact and Honkai: Star Rail, even at maximum settings and high frame rates.
Adding a visual element to the cooling experience, the phone features an innovative IceSense Ultra back panel that shifts color from white to blue as the temperature drops, providing users with real-time thermal feedback and confidence in the device’s performance capabilities.
For gamers, content creators, and heavy users, this translates to sustained, uninterrupted performance during marathon sessions and intensive 4K video recording.
Commitment to Youth Innovation
realme has built its identity by listening to the aspirations of Indian youth—whether it’s their passion for gaming, content creation, or non-stop streaming. Both these prototype innovations address everyday frustrations like mid-game battery drains and thermal throttling during extended usage. By solving these fundamental challenges, realme strengthens its commitment to being the coolest smartphone brand in India—one that seamlessly blends cutting-edge performance with lifestyle needs.
India has been central to realme’s journey since its inception, serving as both a key market and an inspiration hub for innovation. As the brand enters its eighth year, it reaffirms its promise to democratize cutting-edge technology and empower millions of young Indians to “play hard, last longer, and live boldly.”
While these concept phones showcase the future of smartphone technology, market availability is yet to be announced, with industry observers expecting that commercial variants may debut with slightly reduced specifications initially.
