Realme appears to be moving closer to launching its first smartphone with an ultra-large battery, as a new leak has revealed key details about a device sporting a massive 10,001mAh cell.
The company previously showcased a prototype with a 10,000mAh battery earlier this year and hinted at commercial plans for batteries above 7,500mAh. However, until now, Realme’s largest battery phones in the market have topped out at 7,000mAh, including models from its flagship GT lineup.
The latest development comes from the Editor-in-Chief of a Russian technology blog, who shared an image of an unannounced Realme device carrying the model number RMX5107. According to the leaked image, the smartphone is equipped with a 10,001mAh battery, making it slightly larger than the batteries found in the recently announced Honor Win and Win RT, both of which also emphasize long-lasting power.
Alongside the battery details, the leaked unit is shown running Realme UI 7.0 and features 12GB of RAM paired with 256GB of internal storage. While these specifications suggest the device could target upper-mid-range or productivity-focused users, additional storage or RAM configurations may also be offered at launch.
The source further claims that the RMX5107 has already received Hi-Res Audio certification, hinting at stronger multimedia credentials. The device is reportedly in the process of receiving approval for commercial sale in Russia, which indicates that an official announcement could be approaching soon. Once certifications are complete, more details — including processor specs, charging speed, and camera configuration — are expected to surface.
A smartphone featuring a 10,001mAh battery would place Realme among the few manufacturers pushing ultra-high-capacity battery technology in consumer devices. Such a handset is likely to appeal to heavy users, travelers, gamers, and professionals who prioritize multi-day endurance over slim design.
Although Realme has yet to comment on the leak or confirm launch plans, the emerging certifications suggest that the company may be preparing to debut this battery-focused smartphone in select markets in the coming weeks.
