Realme P4 Power vs Redmi Note 15 Pro: both phones launched in India on January 29 and have stepped into the crowded sub-₹30,000 segment. On paper they both emphasize large batteries, high-refresh-rate AMOLED screens and strong camera setups, but specs don’t tell the whole story. Below is a side-by-side comparison of key specs, camera features and pricing to help you understand the real differences.
Display and build quality
The Realme P4 Power sports a 6.8-inch curved AMOLED panel with 1.5K resolution and a 144Hz refresh rate. Realme claims a peak brightness of up to 6,500 nits; the phone also carries IP66, IP68 and IP69 ratings and includes Realme’s ArmorShell Protection for added durability.
The Redmi Note 15 Pro uses a slightly larger 6.83-inch AMOLED display with a 120Hz refresh rate and support for HDR10+ and Dolby Vision. Its peak brightness is rated up to 3,200 nits, and protection comes via Gorilla Glass Victus 2. The Redmi is rated IP68 and IP69K for dust and water resistance.
Performance, software and battery
Both phones are powered by the MediaTek Dimensity 7400 Ultra chipset built on a 4nm process. The Realme runs Realme UI 7.0 based on Android 16, with a promise of three years of OS updates and four years of security updates. Realme also adds a dedicated HyperVision+ AI chip and a large vapor-chamber cooling system to keep thermals in check during heavy use or gaming.
Redmi ships the Note 15 Pro with HyperOS 2 based on Android 15 and promises four major Android updates. The Redmi offers memory and storage up to 12GB RAM and 512GB storage.
Battery is where they differ most: the Realme P4 Power packs a massive 10001mAh silicon-carbon battery with 80W fast charging and 27W reverse charging. The Redmi Note 15 Pro has a 6580mAh battery, which is perfectly adequate for daily use but clearly smaller than Realme’s offering.
Camera
Realme P4 Power features a dual rear camera system led by a 50MP Sony IMX882 primary sensor with OIS, paired with an 8MP ultra-wide lens. For selfies there’s a 16MP front camera.
The Redmi Note 15 Pro leans harder into imaging with a 200MP primary sensor that also includes OIS, plus an 8MP ultra-wide camera and a 20MP front camera. Both phones offer capable camera setups, but if you want very high-resolution photos and more stabilized video, the Redmi appears stronger on paper.
Price
There’s a clear price gap between the two. The Redmi Note 15 Pro is priced at ₹29,999 for the 8GB+128GB variant and ₹31,999 for the 8GB+256GB model. The Realme P4 Power is positioned lower: ₹25,999 for 8GB+128GB and ₹28,999 for 8GB+256GB.
Bottom line
On specs alone, both phones bring a lot to the table—big displays, capable chipsets and solid cameras. Realme wins on battery capacity and starting price, while Redmi edges forward with a higher-resolution main camera and higher top-end storage/RAM options. Your choice will depend on whether you prioritise battery life and value (Realme) or camera detail and higher memory configurations (Redmi).
