In a surprising announcement ahead of its 828 Fan Festival, Realme has revealed a prototype smartphone featuring a 15,000 mAh battery—a capacity larger than many portable power banks.
A New Benchmark in Smartphone Batteries
The news comes shortly after Realme teased a device with a battery exceeding 10,000 mAh. The company has now confirmed that the prototype will house a 15,000 mAh cell, marking one of the largest batteries ever seen in a smartphone.
According to Realme, this enormous power pack is capable of delivering:
- 18.45 hours of continuous video recording
- 50 hours of video playback
- Over 5.18 days of regular smartphone use on a single charge
Innovative Cooling Technology
Alongside the battery reveal, Realme also teased another unique feature—a built-in cooling fan. The fan is designed to reduce the device’s temperature by up to 6°C, addressing the overheating challenges that typically arise in high-capacity smartphones, particularly during gaming or extended streaming sessions.
What’s Next?
Although the company has not yet shared details about the phone’s full specifications or release timeline, this bold move signals Realme’s focus on pushing battery innovation and tackling performance issues in ways that set it apart from competitors.
With its 15,000 mAh battery and integrated cooling system, this prototype could reshape expectations for how long a smartphone can last—and how it handles demanding tasks.
