While Realme is busy teasing the Realme GT 7 series’ launch in different markets, it has also confirmed the existence of a new concept phone. Last month, Honor released the Honor Power phone equipped with a massive 8,000mAh battery, the largest ever battery phone by a mainstream phone brand. The concept phone teased by Realme is equipped with an enormous 10,000mAh capacity battery.

The above image released by Realme showcases a bold concept phone, labelled the “GT 10000mAh.” The back panel of the phone prominently displays “10,000mAh” in large, stylized typography along with the tagline “Power That Never Stops.” It seems to be equipped with a dual-camera system for photography.
According to the brand, the Realme 10,000mAh concept phone packs an ultra-high silicon-content anode battery, offering a 10% silicon ratio—the highest in the smartphone industry—and an energy density of 887Wh/L, making it possible to pack a large battery without adding excessive bulk. Thus, the phone measures only 8.5mm and weighs just above 200 grams. To put into context, the Honor Power, which packs an 8,000mAh battery, has a thickness of only 8mm and weighs 209 grams.
To fit the large 10,000mAh battery, Realme developed a new internal layout called the “Mini Diamond Architecture,” enabling the world’s narrowest Android mainboard at 23.4mm and earning over 60 global patents. A semi-transparent back reveals the internals, merging aesthetics with innovation. Here’s an official hands-on video of the phone.
Realme is expected to hold a global launch event for the Realme GT 7 series later this month. Likely, the Realme GT 10,000mAh concept phone may get showcased at the said event. While this Realme GT concept phone may not be commercially available, it reflects the company’s experimental direction and ambition in pushing battery capacity boundaries in smartphone design.
