Realme phone with a 10,001mAh battery leaks a day after Honor launches 10,000mAh Win series
Just when it looked like Honor had taken the lead in the smartphone battery race, Realme seems to have quietly raised the bar, only by the smallest possible margin. A new leak shows an unnamed Realme smartphone with a 10,001mAh battery, surfacing just a day after Honor launched its Win and Win RT phones with 10,000mAh batteries.
The leaked device, shared by the editor-in-chief of a Russian tech blog, carries the model number RMX5107. The image shows the phone running Realme UI 7.0 with 12GB of RAM and 256GB of storage. According to the source, the phone has already been certified for Hi-Res Audio and is currently going through regulatory approvals for sale in Russia, which suggests this is more than just an internal prototype.

The timing is interesting because Honor has just made a clear push into the ultra-big-battery category. The Honor Win and Win RT are both built around 10,000mAh batteries and are positioned around endurance rather than slim designs or flagship-grade hardware. They are meant for users who want their phones to last for days, even if that means accepting a heavier device.
Honor is also taking things a step further with the upcoming Honor Power 2, an iPhone 17 Pro lookalike but with a massive battery. The company has confirmed that the phone will launch in China on January 5th and will pack a 10,080mAh battery.
Realme, meanwhile, has been laying the groundwork for this for months. Back in May, the company showed off a 10,000mAh battery prototype and said it would first bring a 7,500mAh phone to market, followed by a 10,000mAh model. So far, Realme’s biggest batteries on sale have been around 7,000mAh, including on this year’s flagship, the GT 8 Pro. The appearance of the RMX5107 suggests that the long-promised upgrade may finally be close.
What’s making this possible is the wider shift to silicon-carbon battery technology, which allows brands to push capacity higher without turning phones into thick bricks. Over the past year, 6,000mAh and 7,000mAh batteries have become common, and 10,000mAh now looks like the next milestone.
For buyers, phones like these will make sense only if battery life sits at the very top of the priority list. Frequent travellers, outdoor users, or anyone tired of carrying a power bank will see the appeal. Others may still prefer more balanced phones that trade extreme endurance for lighter designs, better cameras or faster charging.
Realme has not confirmed when this 10,001mAh phone will launch or where it will be sold. But coming right after Honor’s announcement, the leak feels less accidental and more like a deliberate reinforcement, even if, for now, the difference is just one extra milliamp-hour in the 10,000mAh battery phones table.
