Realme has unveiled its new P4 Power phone, featuring a massive 10,001mAh battery that can last up to three and a half days of light use. The device aims to bring back the long-lasting battery life that many modern phones lack.
The P4 Power uses Realme’s Titan silicon-carbon battery and supports 27W reverse charging. This allows the phone to charge other devices in emergencies, essentially acting as a portable power bank.
Unlike earlier large-battery phones that were bulky and heavy, the P4 Power remains slim and modern-looking. It weighs 218g, similar to the Samsung Galaxy S25 Ultra, making it easy to handle despite its huge battery.
Realme’s battery slightly edges out the 10,000mAh Honor Win and 10,080mAh Honor Power 2 in China, though the Honor devices currently have limited availability outside of China. The P4 Power, launching in India on January 29, 2026, will likely be easier for international buyers to access.
In a market where phones are increasingly similar, Realme’s focus on long battery life and practicality may appeal to users who want a reliable device without daily charging or a high price tag.
