Realme has revealed a new concept smartphone called the Realme GT 10,000mAh, introducing it alongside teasers for the upcoming GT 7 series. This concept device focuses on groundbreaking battery technology, boasting a massive 10,000mAh capacity — the largest ever proposed by a major smartphone brand. It follows the recent release of the Honor Power phone in April, which came with an 8,000mAh battery, but Realme has taken the concept even further.
Despite its unusually large battery, the Realme GT 10,000mAh concept phone maintains a surprisingly slim and lightweight design. The device measures only 8.5mm in thickness and weighs just over 200 grams. This feat is made possible by using an ultra-high silicon-content anode battery, featuring a 10% silicon ratio — the highest in the smartphone industry — and an energy density of 887Wh/L. These specifications allow Realme to house a much larger battery without adding excessive bulk.

To fit the high-capacity battery into a sleek frame, Realme developed a new internal layout called the “Mini Diamond Architecture.” This structure supports what Realme claims to be the world’s narrowest Android mainboard, measuring just 23.4mm. The design innovation has earned the company over 60 global patents. Aesthetically, the phone also features a semi-transparent back, offering a glimpse of the internal components and reinforcing its status as a concept device.
The back panel is boldly branded with “10,000mAh” and the tagline “Power That Never Stops,” emphasizing the phone’s key selling point. While it includes a dual-camera setup, the highlight remains its battery capacity and slim form factor.
Although the Realme GT 10,000mAh may not be released commercially, it is expected to be showcased during the upcoming GT 7 series launch. The concept illustrates Realme’s ambition to push the boundaries of battery performance in modern smartphones.
