Realme has shown off a prototype smartphone with a huge 10,000 mAh battery. Despite its large battery, the phone is only 8.5mm thick and weighs just 215 grams. Chace Xu, the president of Realme Global Marketing, shared this design feat in a recent unboxing video.
Smallest Android Motherboard Yet
To pack such a big battery in a slim phone, Realme used a silicon-anode battery with 10% silicon. This increased the energy density to 887Wh/L. The company also built the smallest Android motherboard, which measures only 23.4mm tall. This smaller motherboard made room inside the phone for the large battery without adding bulk or weight.
Video Demonstration
The two-minute video shows the whole device, highlighting both the design and the inside tech. It offers a detailed look at how Realme squeezed high power capacity into a compact phone. Multiple angles give a close-up view of the components and show how they fit together.
Although the prototype demonstrates Realme’s progress in battery and hardware innovation, the device is not slated for public release. Instead, it serves as a testing ground for upcoming models, including the Realme GT 7 series, which is expected to feature smaller—yet still significant—battery capacities.
Additionally, it showcases how it is very much possible to fit a humongous battery capacity in a compact footprint. Whether Realme plans to make this technology available in future commercially available smartphones remains to be seen.
