Realme appears to be edging closer to a truly marathon smartphone. A leaked image and certification notes point to an unnamed Realme model packing a staggering 10,001 mAh battery — and the rumor mill is already buzzing.
What the leak reveals
The device surfaced with the model number RMX5107, reportedly shared by the Editor-in-Chief of a Russian tech blog. The snapshot lists 10,001 mAh as the battery capacity — technically 1 mAh more than the recent Honor Win and Win RT announcements — and shows the phone running Realme UI 7.0.
On the memory front, the leak mentions a configuration with 12GB of RAM and 256GB of storage. That doesn’t rule out other variants, but for now those are the confirmed figures in the image. The handset is also said to be certified for Hi-Res Audio and is undergoing sales certification in Russia, which hints that an official regional reveal could come soon.

Realme first teased a 10,000 mAh prototype back in May and had promised a 7,500 mAh model this year. In practice, the brand’s recent releases have topped out around 7,000 mAh — including the GT 8 Pro — so a 10,001 mAh commercial device would be a notable jump.
What does a 10,001 mAh battery mean in real life? Expect exceptional standby and multi-day use on moderate workloads, but also a heavier, thicker chassis and a need for robust thermal and charging systems. Realme hasn’t confirmed charging specs, so whether this phone will pair that huge battery with ultra-fast wired or wireless charging remains to be seen.
For now, treat the RMX5107 as a credible leak: image-backed, partially certified and likely heading through local approvals. If Realme follows typical timelines, more concrete news — official teasers, specs and launch dates — should appear in the coming weeks.
