realme has introduced its most ambitious concept phone yet the GT7 with a massive 10,000mAh battery, aiming to redefine battery performance in smartphones.

Despite its ultra-high capacity the GT7 maintains a slim profile under 8.5mm and weighs just over 200g, showcasing realme’s commitment to balancing power and design. At the heart of this innovation is an ultra-high silicon-content anode battery, boasting a 10% silicon ratio currently the highest in the industry. With an energy density of 887Wh/L, the battery sets a new benchmark for lithium-ion technology.

realme has also reimagined the phone’s internal design with its new “Mini Diamond Architecture,” enabling a record-breaking 23.4mm wide Android mainboard. This space-saving structure has earned over 60 international patents and is visible through the semi-transparent back of the concept device.

Known for pushing the limits of fast-charging—ranging from 150W in the GT Neo3 to 240W in the GT3—realme continues to pioneer battery tech. With the GT7 concept, the brand hints at even more innovations to come in its upcoming GT7 series.
