realme unveiled a new concept smartphone featuring a whopping 10,000mAh battery with silicon-anode technology back in May this year, measuring 8.5mm, and weighing 212 grams. Today, the company has posted a new teaser that says ‘THE BIGGEST JUST GOT EVEN BIGGER’.
realme added that it will redefine the limits once more. Last August at the 828 Fan Festival, the company unveiled its 320W SuperSonic Charge technology that can charge a 4420mAh battery in just 4 minutes and 30 seconds.
NOT BIG ENOUGH? NOW, IT IS.

The teaser video shows Chase Xu, realme’s vice president of realme, and president of realme global marketing creatively uses a visual metaphor of magnification to emphasize the need for larger battery capacities, culminating in the reveal of “1x000mAh,” suggesting a significant leap in battery size, possibly up to 12,000mAh or more, aiming to address consumer demand for longer battery life.
In a post, he said, “Battery limits broken—again. Finally meets my standards! But how big, exactly? August 27, you’ll see.”
We should know more details in the coming days, before the device goes official next Wednesday.
