In anticipation of the Realme 828 Fan Festival, the company has dropped hints about cutting-edge smartphones packing fresh features. We’ve caught glimpses of a Realme device boasting an enormous 15,000mAh battery, set to launch beside the intriguing Realme Chill Fan Phone, which incorporates an integrated AC-style active cooling mechanism.

That beefy-battery model from the Chinese tech giant touts enough juice for up to 50 hours of continuous video streaming after a full top-up. Meanwhile, the teased Chill Fan Phone grabs attention with its “AC” cooling setup—not entirely new, as various gaming handsets already sport built-in fans, but this one claims a pioneering twist by dropping the device’s core temp by as much as 6°C.

Plus, users can switch the AC function on or off at will. The promo clip reveals a phone with a standard look, except for a discreet side vent that expels air strong enough to snuff out a candle flame or nudge a rubber duck across water. As a reminder, the Realme 828 Fan Festival launches on August 27, 2025, at 11 a.m. CST. Time will tell if this Chill Fan Phone delivers genuine breakthroughs or turns out to be mere flair.
