Ahead of the upcoming Realme 828 Fan Festival, Realme shared teasers for smartphones with innovative new tech. We’ve already seen the upcoming Realme phone with a massive 15,000mAh battery, but this model is arriving alongside a new Realme Chill Fan Phone with a built in AC active cooling system.
Realme Teases New Chill Fan Phone with Built-In AC Cooling
The Chinese brand’s 15,000mAh phone was seen with a huge battery that promises an impressive 50 hours of video playback on a single full charge. Another model that got teased was the Realme Chill Fan Phone. This isn’t the first time we’ve seen an active cooling system with a physical fan on a smartphone. There are plenty of gaming smartphones that feature this technology. However, what makes the Chill Fan Phone stand out is the “AC” cooling.

Looking at the official teaser, Realme is working on the world’s first “AC” phone that brings up to 6°C reduction in core temperature. Another notable aspect of this new cooling tech is that it can even toggle the AC on and off. The video trailer showcases the smartphone with a familiar design but with a small vent on the side frame.
You can even see this vent blowing out enough air to blow out a candle and pushing a rubber ducky forward in a container of water. To recall, the Realme 828 Fan Festival is set to kick off on 27th August 2025 at 11 AM China Standard Time. It remains to be seen whether the Realme Chill Fan Phone offers real innovation or if it’s just a gimmick.
