realme has released two new concept phones with pretty extreme features.
The first realme concept phone has an ultra-large 15,000mAh battery while retaining an impressively thin frame. As per realme, the device can last up to 50 hours of video playback, 18 hours of recording video, or 5 days of normal use.
A phone with a 15000mAh battery. What does that really mean?

realme also said it can last up to 30 hours of gaming and 3 months of standby. realme also highlighted that its reverse charging feature lets you use it like a power station.
The video above shows that it can charge a DJI drone, power a mini fridge, an electric fan, and even a tube fan.
This next one is pretty ridiculous, but could actually benefit a lot of users in tropical countries like the Philippines. It’s called the realme Chill Fan Phone concept, which is the first smartphone with a built-in air conditioner (AC).
Say hello to the realme Chill Fan Phone, the world’s first “AC” phone! Game cooler with up to 6°C reduction in core temperature, and the AC feature works just like a regular air conditioner—you can turn it on and off as you please.

Cold air comes out of a vent from the lower left side of the phone. While it’s powerful enough to blow a candle or move a rubber duck floating in water, the goal is to keep the device and your hands cool during heavy gaming sessions.
We shall see these technologies arrive on a market-ready smartphone in the future.
