Now, the Chinese phone maker on Wednesday (August 27) showcased a new concept phone with double the battery capacity of P4 series.

At the Realme 828 Fan Festival in Beijing, the company showed a phone with a massive 15,000mAh battery.

With a full charge, it can deliver up to 120 hours of battery life, which is equivalent to five days under normal usage. It can support 50 hours of video playback. It is enough to binge-watch TV shows or movies for two days straight.

It can also support 18 hours of video recording and can be used as a power bank to charge to other devices.

There is no other official information on the device, such as display and processor configuration, but the concept device has received a good response on social platforms.

As per recent reports, the Realme concept phone will feature a 6.7-inch full HD display and come with a fingerprint sensor.

Also, it is likely to run Android 15-based Realme UI 6 and house a 4nm class MediaTek Dimensity 7300 octa-core processor with 12GB of RAM and 256GB of storage.

Realme also showcased another concept phone, which comes with a built-in fan. The company's vice president, Chase Xu calls it 'Chill Fan Phone'. Thanks to the fan, it can reduce temperatures by up to 6 degrees Celsius while maintaining full FPS (frames per second) during heavy-load gameplay.

"These innovations underscore our continuous pursuit of redefining technological boundaries. We are eager to hear your thoughts—which concept captures your imagination?, said Chase Xu, vice president, Realme.

Depending on the feedback from fans, Realme will decide whether to bring the commercial variants of the new concept phones.

Given the increased use of social media platforms and Over-The-Top (OTT) apps for entertainment among consumers, the phone with a 15,000mAh battery will definitely find takers in all age groups, young and old, in India.

For the uninitiated, 828 Fan Festival is celebrated to mark the Realme's foundation day. Though, it seperated from parent firm Oppo on May 4, 2018, the company celebrates it founding day on August 28.
