Realme GT 10,000mAh Concept Phone Unboxed; Revealed Slim Design, Key Specs

Realme has unveiled a concept smartphone, the Realme GT 10,000mAh in this week, featuring a massive 10,000mAh battery. In a recent unboxing video shared by realme’s VP and Chief Marketing Officer, Chase Xu, more details about the device have come to light.

The phone sports a sleek design, measuring just 8.5mm thick and weighing 212 grams—made possible by silicon-anode battery technology, which delivers an impressive energy density of 887Wh/L. This advancement allows for extended battery life without adding bulk, outperforming conventional smartphone batteries.

A standout innovation is the “Mini Diamond Architecture,” which incorporates the world’s narrowest Android mainboard at just 23.4mm. Supported by 60 global patents, this design enables the integration of the oversized battery while still allowing for 100W fast charging.

To ensure durability and safety, the battery employs a ‘triple cold press’ process to prevent swelling, CGT technology on the cathode for uniform electrolyte distribution, and a reinforced double-groove aluminum film for enhanced drop and impact resistance.

The concept phone is also confirmed to include a 6.7-inch OLED display and the MediaTek Dimensity 7300 chipset. However, a commercial release isn’t expected before 2026.
