SHENZHEN, CHINA — August 24, 2025:
Global smartphone brand realme is set to unveil a groundbreaking mobile innovation at its upcoming 828 Anniversary Celebration on August 27—a world-first 10,000mAh+ high-density battery, establishing a new frontier in smartphone endurance and power efficiency.
This revolutionary battery, developed with 100% full silicon anode technology, boasts an unprecedented energy density of 1200 Wh/L—the highest ever achieved in a smartphone. Designed for marathon gamers, content creators, and heavy users, the battery promises extended usage without compromising on device size or aesthetics. This innovation will be the highlight of the 828 Fan Festival, held annually to commemorate realme's founding and engage its global fanbase.
realme's latest battery milestone builds upon its recent track record of industry-firsts. In 2024, the company introduced 320W SuperSonic Charging, which powers a 4,420mAh battery to full in just 4 minutes and 30 seconds. Earlier in 2025, realme launched the GT 7, the world’s first smartphone to combine a 7,000mAh battery with 120W fast charging. Three months ago, it also showcased a concept phone with a 10,000mAh battery at 887 Wh/L—further demonstrating the brand’s dominance in battery technology.
In a statement, realme emphasized that this innovation responds to the evolving demands of younger, always-connected users. By delivering greater battery life without bulk, realme continues to lead where performance meets practicality.
Adding to the excitement, the company has teased the launch of a second “game-changing” technology during the celebration. While specific details remain under wraps, realme hinted that the reveal will further affirm its position at the cutting edge of mobile tech.
The 828 Anniversary will be streamed live across realme’s official platforms, with fans and tech enthusiasts around the world invited to join the unveiling of what the company promises will be a glimpse into the next era of smartphone evolution.
