New Delhi, January 21, 2026: realme, India’s most recommended youth smartphone brand, announced a significant advancement in smartphone power innovation with the introduction of its 10001mAh Titan Battery, debuting on the realme P4 Power 5G. As India’s first and biggest 10001mAh battery smartphone, the device marks realme’s entry into the 10000mAh+ era and redefines expectations around endurance, safety, and long-term battery reliability in everyday smartphones.
At the heart of this breakthrough is next-generation silicon-carbon anode technology, enabling realme to integrate ultra-high battery capacity without compromising portability. Despite housing a 10001mAh battery, the realme P4 Power 5G features a 9.08mm slim profile and an ultra-light 219g body, making it the world’s thinnest and lightest smartphone in the 10001mAh category. This engineering achievement delivers multi-day power in a form factor designed for daily comfort and usability.
Positioned as an all-scenario power champion, the Titan Battery is built to support real-world usage across gaming, entertainment, navigation, learning, and travel. Internal testing shows the device can deliver up to 32.5 hours of YouTube playback, 11.7 hours of continuous BGMI gaming, and over 21 hours of navigation on a single charge.
Battery safety has been engineered at a system level. The Titan Battery incorporates a five-layer battery safety architecture, combining advanced protective coatings, reinforced structural materials, smart power-disconnect mechanisms, and enhanced internal insulation. The realme P4 Power 5G is also the world’s first smartphone with a 10,000mAh+ battery to pass military-grade shock tests, reinforcing its resilience in both everyday use and extreme conditions.
Designed to operate reliably across diverse environments, the Titan Battery supports safe and normal usage in temperatures ranging from -30°C to 56°C, ensuring consistent performance in extreme cold, high heat, and challenging outdoor conditions. Further strengthening its safety credentials, the realme P4 Power 5G is the world’s first and only smartphone with a 10,000mAh+ battery to receive TÜV Rheinland’s 5-Star battery certification, underscoring its standards for battery safety, stability, and durability.
Beyond capacity and safety, realme has focused on long-term battery health. With its 8-year battery health standard, the Titan Battery leverages realme’s Titan Long-Life Algorithm, combining AI-driven charging intelligence with silicon aging control. The larger battery capacity reduces charging frequency, helping slow degradation over time and enabling the battery to retain over 80% health even after years of usage, setting a new benchmark for battery longevity in its segment.
Complementing its endurance credentials, the realme P4 Power 5G supports all-scenario bypass charging, reducing heat and battery stress during high-load activities such as gaming, video playback, and navigation. The device also features 27W reverse charging, allowing it to power other smartphones and accessories when needed.
With the introduction of the Titan Battery, realme strengthens its position as a Battery Tech Pioneer, moving beyond capacity figures to deliver a holistic power solution that balances endurance, safety, slim design, and long-term reliability, engineered for modern, always-on lifestyles.
