Battery anxiety has become a familiar part of modern smartphone ownership. Many users plan their day around chargers, power banks, and low-power modes, expecting their phone to tap out before nightfall. Realme is betting that frustration has reached a breaking point.
The company’s latest device, the Realme P4 Power 5G, takes aim squarely at endurance. It arrives with a 10,001 mAh battery, a capacity that dwarfs most mainstream smartphones. For context, Samsung’s Galaxy S25 Ultra ships with a 5,000mAh cell—roughly half the size.
On paper, Realme’s numbers are eye-catching. The company says the phone can deliver up to 932.6 hours of standby time, 32.5 hours of YouTube playback, and 185.7 hours of music listening. These are ideal-condition estimates, but they underscore the company’s core message: this phone is built to last.
Realme goes further in its official materials, claiming the battery offers “week-long endurance.” At the same time, the company strikes an unexpectedly cautious tone elsewhere, suggesting the phone will last around 1.5 days between charges. That discrepancy likely reflects different usage scenarios. Heavy users who stream, game, and multitask aggressively may land closer to the lower figure, while lighter users could stretch well beyond it. Realme also contrasts this with what it describes as “other” phones that require charging twice a day, positioning the P4 Power 5G as an antidote to constant top-ups.
Oversized batteries are not new to the smartphone world. Past experiments have pushed capacities even higher, including devices with batteries approaching 18,000mAh. Those phones, however, often came with serious trade-offs: bulky designs, awkward ergonomics, and weights that made daily use impractical.
This is where Realme’s approach stands out. The P4 Power 5G looks like a conventional mid-range smartphone and weighs just 219 grams. That figure puts it well within the range of everyday devices, making the phone feel more like a normal handset than a niche endurance experiment. Realme has not shared exact dimensions, but promotional images suggest the phone is only slightly thicker than its predecessor, the Realme P4 5G, which featured a 7.58mm body and a 7,000mAh battery.
The battery does more than simply last longer. Realme includes 27W reverse charging, allowing the phone to function as a power bank for other gadgets. The company also says the device can continue running even when plugged in at just one percent battery, a small but meaningful feature for users who push their phones to the edge.
Beyond battery life, the P4 Power 5G fits comfortably into the mid-range Android category. The phone features a 6.78-inch AMOLED display with a 144Hz refresh rate, aimed at smooth scrolling and gaming. It runs on MediaTek’s Dimensity 7400 processor and includes 12GB of RAM, according to Geekbench listings. On the back sits a triple-camera system, though Realme has not yet disclosed detailed camera specifications.
Realme plans to launch the P4 Power 5G in India on January 29. The device will be available in three finishes: TransOrange, TransSilver, and TransBlue. The company has not shared pricing or details about availability outside India.
The broader implication is clear. As smartphones add brighter displays, faster chips, and more AI-driven features, battery life has struggled to keep pace. Realme’s P4 Power 5G suggests a different priority: solving a daily pain point rather than chasing marginal performance gains. For users tired of watching their battery percentage tick down by mid-afternoon, that focus alone may be enough to make this phone stand out.
