Realme has revealed a new prototype phone that comes with a massive 10,000mAh battery and 320W fast charging. This news comes just before the global launch of the Realme GT 7.
The prototype is not just powerful — it’s also very slim, measuring only 8.5mm thick and weighing 215g. Realme used 10% silicon anode in the battery, which helped it reach an impressive energy density of 887Wh/L.
To make room for the large battery, the company also made the phone’s motherboard extremely small — just 23.4mm tall, the smallest ever in an Android phone.
Chace Xu, Realme’s Global Marketing President, shared a 2-minute video unboxing the prototype and explaining how the phone was built. The video also shows off the sleek design and advanced internals.

While this is just a prototype, Realme has a history of turning its concepts into real products quickly. The 240W charging system that debuted in 2023 was also first shown as a concept and later released to the public.
The Realme GT 7 may not have a 10,000mAh battery or 320W charging, but this prototype gives a clear glimpse of Realme’s bold future in smartphone technology.
