Realme P4x Ultra: Realme is gearing up to expand its P-series lineup in India with the launch of the Realme P4x Ultra, a smartphone that could significantly raise the bar for battery performance in the mid-range segment. The device has now been spotted on India’s Bureau of Indian Standards (BIS) certification database, strongly indicating an imminent India launch.
According to the BIS listing, the Realme P4x Ultra carries the model number RMX5107. While the certification does not reveal hardware specifications, such appearances typically suggest that the official launch is just weeks away. Based on industry timelines and recent leaks, the smartphone is expected to debut in the Indian market by late January 2026.
Massive Battery Could Be a Game Changer
The biggest highlight surrounding the Realme P4x Ultra is its rumoured battery capacity. Tipsters and online discussions, including Reddit threads, suggest that the phone may feature a 10,000mAh battery or even larger. If confirmed, this would place the device among smartphones with the largest batteries ever launched in India.
Such a massive battery could deliver multiple days of usage on a single charge, making the phone especially attractive for heavy users, gamers, travelers, and consumers in regions where frequent charging is inconvenient. While Realme has not officially confirmed the battery size, the speculation has already generated strong buzz among tech enthusiasts.
Builds on the Foundation of Realme P4x 5G
Realme has already introduced the Realme P4x 5G in India, which features a 7,000mAh battery, a 144Hz display, and the MediaTek Dimensity 7400 Ultra processor. The upcoming P4x Ultra is expected to sit above this model, focusing on even stronger battery life, enhanced performance, and optimized 5G connectivity.
With both P4x 5G and P4x Ultra expected to coexist in the lineup, Realme appears to be targeting users who prioritize long battery endurance without compromising on modern features like fast internet speeds and smooth display performance.
Realme P4x Ultra India Launch Outlook
While pricing and full specifications remain under wraps, the BIS certification confirms that Realme is preparing the P4x Ultra specifically for the Indian market. If the leaked battery details turn out to be accurate, the smartphone could redefine expectations in the affordable-to-mid-range segment and strengthen Realme’s position in India’s highly competitive smartphone space.
More official details are expected to surface in the coming weeks as the launch timeline approaches.
