When I first heard about the Realme P4 Power boasting a colossal 10,001mAh battery, I was both intrigued and skeptical. Could a smartphone truly deliver such unprecedented battery life without compromising on design and performance? Determined to find out, I spent a week with this device, pushing it to its limits.
## Unboxing and First Impressions
Upon unboxing, the Realme P4 Power immediately stood out. Despite housing a battery larger than some power banks, the phone maintains a surprisingly sleek profile. Measuring just 9.1mm in thickness and weighing 219 grams, it felt comfortable in hand, defying my expectations of bulkiness.

## Design and Build Quality
The device sports a 6.8-inch 1.5K OLED display with a 144Hz refresh rate, offering vibrant colors and smooth scrolling. The curved edges add a touch of elegance, and the peak brightness of 6,500 nits ensures excellent visibility even under direct sunlight.

## Performance Under the Hood
Powered by the MediaTek Dimensity 7400 Ultra chipset, paired with up to 12GB of LPDDR4X RAM and UFS 3.1 storage, the P4 Power handles daily tasks with ease. Multitasking was seamless, and even during intensive gaming sessions, the device remained responsive without noticeable lag.

## Camera Capabilities
The camera setup includes a 50MP Sony IMX882 main sensor with OIS, an 8MP ultra-wide lens, and a 2MP sensor. In well-lit conditions, photos were sharp with accurate colors. However, in low-light scenarios, the performance was average, with some noise creeping in. The 16MP front camera delivered satisfactory selfies, suitable for social media uploads.

## The Battery Experience
Now, to the star of the show—the 10,001mAh battery. Realme claims up to 932 hours of standby time and over 72 hours of calling. ([gizmochina.com](https://www.gizmochina.com/2026/01/29/realme-p4-power-5g-launch-india-10001mah-battery-specs-price/?utm_source=openai)) In my real-world usage, the phone lasted an impressive five days on a single charge, with around 10 hours of screen-on time each day. This included browsing, streaming videos, and occasional gaming. Charging the massive battery was surprisingly quick, thanks to the 80W fast charging support, reaching 50% in approximately 36 minutes.
