The smartphone industry is entering a new era of battery innovation and thermal management, and Realme is leading the charge. At the 828 Fan Festival 2025, Realme officially showcased two groundbreaking devices: the Realme 15,000mAh Battery Phone and the Realme Chill Fan Phone. These devices not only push the boundaries of what a smartphone can achieve in terms of endurance and performance but also reshape how we think about cooling solutions in mobile technology.
With its
latest announcements, Realme has proven once again that it is not afraid to
innovate and disrupt the market. Let’s dive deeper into what makes these two
devices so extraordinary.
🔋 Realme 15,000mAh Battery
Smartphone – A Powerhouse in Your Pocket
One of the
biggest highlights of the event was the unveiling of the Realme
15,000mAh battery smartphone. This is not just another phone with a bigger
battery; it’s a complete engineering marvel.
📏 Slim Yet Powerful
Despite
housing a massive 15,000mAh battery, Realme has managed to make the
phone:
- 42% slimmer than
expected, measuring only 8.89mm thickness.
- 68% lighter compared
to traditional power banks of the same capacity.
This
slimness and reduced weight have been made possible through new battery
materials and cutting-edge engineering.
⚡ Revolutionary Battery Technology
Realme
detailed the three crucial steps that made this possible:
- All-Silicon Content Anode Battery –
The world’s first of its kind with 25% silicon content,
significantly improving energy storage.
- Unmatched Energy Density –
The phone achieves the world’s highest energy density of 1200Wh/L,
ensuring more power in less space.
- Advanced Packaging –
With an ultra-thin mainboard of just 23.4mm, and
state-of-the-art battery lamination, the battery thickness is
reduced to just 6.48mm.
This level
of miniaturization and efficiency is a new world record in smartphone
engineering.
⏳ Unbelievable Battery Life
Realme
claims the 15,000mAh phone can deliver:
- 18.45 hours of
continuous video recording.
- 30 hours of non-stop gaming.
- 50 hours of video playback.
- 5.18 days of regular usage on a single
charge.
- Up to 3 months of standby time in airplane mode.
This means
users will no longer need to worry about charging their phone every night. For
heavy users, travelers, or gamers, this is a dream device.
📱 Other Key Specifications
Beyond its
massive battery, the phone packs premium specs:
- 6.7-inch OLED display for
vibrant visuals.
- MediaTek Dimensity 7300 SoC for
powerful performance.
- 12GB RAM and 256GB storage for
seamless multitasking.
- 80W SuperVOOC fast charging to
ensure the giant battery charges quickly.
This phone builds upon the earlier 10,000mAh Realme concept phone, but takes the technology even further.

❄️ Realme Chill Fan Phone – The
World’s First “AC Phone”
While most
companies focus solely on battery life or performance,
Realme has addressed another critical issue—heat management. Introducing
the Realme Chill Fan Phone, marketed as the world’s first true “AC
Phone.”
🔥 Advanced Cooling Technology
The Chill
Fan Phone incorporates:
- 7700mm² VC Cooling combined
with active fan dissipation.
- Thermoelectric Cooling (TEC) –
a tiny semiconductor that can reduce the device’s core
temperature by 6°C, which is 2-3x more effective than
traditional vapor chambers.
This
ensures that the phone stays cool even under heavy loads, such as long gaming
sessions or extended video recording.
🌡️ Dynamic IceSense Ultra Design
Another
unique feature is the IceSense Ultra gradient effect:
- The phone’s back changes from white to blue when
the temperature drops from 45°C to 38°C.
- This gives users a visual indication of cooling performance in
real time.
Realme
tested the phone in a popular anime strategy game running at full FPS,
and results showed an impressive 6.2°C reduction in temperature.
🚧 Production Timeline
While
the Chill Fan Phone has generated a lot of excitement, Realme
has not yet confirmed when it will enter mass production. However,
industry insiders suggest that it could arrive soon after the 10,000mAh
battery phone release in 2026.
🌍 The Bigger Picture – Why This
Matters
Realme’s
new launches mark a turning point for the smartphone industry.
- For Heavy Users & Gamers 🎮: The 15,000mAh battery ensures days of uninterrupted usage, while
the Chill Fan Phone guarantees smooth gaming without overheating.
- For Travelers & Creators ✈️📸: Long-lasting battery life and advanced cooling are perfect for
content creators and frequent travelers who need reliable performance on
the go.
- For Innovation Enthusiasts 🚀: These devices prove that Realme is not just following trends but
setting them.
🏆 Conclusion
The Realme
15,000mAh Battery Phone and the Realme Chill Fan Phone showcase
a bold vision of the future—longer-lasting, cooler, and more reliable
smartphones.
While
availability details are still under wraps, one thing is clear: Realme
is pushing smartphone innovation to new heights. With these devices, the
company is redefining user expectations, paving the way for smarter,
more powerful, and more sustainable technology.
