We’ve all been there. You’re halfway through a long day, and your phone hits the dreaded 15% mark.
Realme seems tired of the struggle. After months of teasing "concept" tech,
a new leak has finally unmasked a retail-ready smartphone—model
RMX5107—carrying a staggering
10,001 mAh battery.
Key Points:
- The Realme RMX5107 features a record-breaking 10,001 mAh battery.
- Silicon-Carbon (Si/C) technology allows the phone to stay under 8.5mm thick.
- The device has been spotted in Russian certification databases for a 2026 launch.
- Hardware includes 12GB RAM, 256GB storage, and Realme UI 7.0.
- This model surpasses the Honor Win series by a single milliamp-hour.
No, It’s Not a Brick
The most shocking part? It isn't a rugged, chunky device meant for construction sites. Leaks from the 828 Fan Festival suggest Realme is using Silicon-Carbon (Si/C) battery tech. This allows for much higher energy density. Imagine the capacity of a power bank squeezed into a frame that is just 8.5mm thick. It’s basically physics-defying.
While the current GT 8 Pro already wows users with its 7,000 mAh "Titan" battery, this new model pushes the boundary even further. The "plus one" mAh at the end of the 10,001 rating feels like a cheeky nod to competitors like Honor, whose own "Win" series stops at exactly ten thousand.
What We Know So Far
Internal certifications in Russia have already started clearing the path for sale. Here is the hardware we are looking at:
- Memory: A solid 12GB of RAM paired with 256GB of storage.
- Software: It’s running Realme UI 7.0, which is built to handle the aggressive power management needed for such a massive cell.
- Charging: While not officially confirmed for this specific model, Realme’s 320W "SuperSonic" charging is the rumored partner for this battery. You could theoretically fill this massive tank in the time it takes to brew a cup of coffee.
The Real-World Impact
For the average user, 10,001 mAh means about five days of normal use. For gamers, it means an entire day of high-refresh-rate play without ever touching a cable. If Realme can actually launch this globally in early 2026, the "low battery anxiety" era might finally be over.
