Realme is poised to potentially revolutionize the Indian smartphone market with the launch of a phone sporting a massive 10,000 mAh battery, possibly by the end of January 2026. This device, speculated to be the Realme P5 and a successor to the Realme P4, has been making waves in the tech community, with leaks and certifications hinting at its imminent arrival.
The buzz started with tipster Yogesh Brar revealing that a Realme phone with model number RMX5107 received BIS certification in India, suggesting an impending launch. This certification, coupled with earlier leaks, fueled speculation about the phone's massive battery capacity. Realme itself teased a 10,000mAh battery prototype in May 2025, adding further weight to the rumors.
If the rumors hold true, this Realme phone could be a game-changer, offering users two to three days of heavy usage on a single charge. This would be a significant leap from the current standard, where most flagship phones offer battery capacities between 5,000mAh and 6,500mAh. For instance, the Realme GT 7 Pro has a 6,500mAh battery. Even phones with larger batteries, like the POCO F7 with its 7,550mAh cell, would be dwarfed by this new Realme device.
The key to achieving such a large battery capacity without compromising the phone's design lies in silicon-carbon battery technology. This technology allows manufacturers to pack more power into a smaller space. Leaked specifications suggest the phone will have a high energy density of around 887Wh/L, allowing it to remain surprisingly thin (under 8.5mm) and relatively light (around 210g) despite the massive battery.
Other rumored specifications include Realme UI 7.0 based on Android 16, 12GB of RAM, 256GB of storage, and Hi-Res Audio certification. However, details about the chipset, camera setup, and charging speeds remain unknown. Given Realme's P-series history, it is expected to feature a mid-range MediaTek Dimensity chipset. To accommodate the large battery, compromises might be made in other areas, such as slower charging speeds or a less advanced camera system. The price is expected to be in the $250 to $300 range.
Realme isn't the only company exploring larger battery capacities. Honor has already launched the Power 2 with a 10,000mAh battery, and Redmi is rumored to be testing 9,000mAh configurations. iQOO already sells phones with 8,000mAh batteries. This trend indicates a growing focus on multi-day battery life as a key selling point for smartphones.
A dedicated microsite on Flipkart hints at the imminent arrival of the new P-series phone, further building anticipation. The listing showcases the launch timeline of previous P-series models, from P1 to P4, suggesting the new phone could be launched soon.
If the rumors are accurate, Realme's new phone could be a significant step forward in battery technology, offering users unparalleled battery life without sacrificing design or performance. While some compromises may be necessary in other areas, the phone is poised to be a strong contender for users who prioritize battery life above all else.
