The realme P4R 5G has the larger advertised battery and faster rated charging; the Xiaomi Redmi 15 5G has an official India listing for an FHD+ display on Xiaomi’s global page and a stated software-update commitment on its India page. Neither is a clear all-round winner from specifications alone: choose by the features that matter to you, then compare live prices for matching memory variants.
Redmi 15 5G vs realme P4R 5G: key specifications
This comparison is for the India-market Xiaomi Redmi 15 5G and realme P4R 5G. The two manufacturers’ pages do not establish every comparable detail on the same basis, so the table distinguishes official India specifications from manufacturer-advertised claims and secondary listings.

Capacity and charging wattage are not a head-to-head battery-life test. Actual endurance depends on usage, network conditions, settings and other factors, and the available sources do not establish which phone lasts longer in comparable real-world use.
How do their displays compare?
Both brands advertise a 144Hz refresh rate. realme also claims 1200 nits peak brightness for P4R. Xiaomi’s global Redmi 15 page lists a 6.9-inch FHD+ display, while 91mobiles describes P4R as HD+. Because the Xiaomi display details cited here come from a global page rather than the India specification page, and the realme page does not state the resolution in the cited material, confirm the exact India-variant resolution before treating FHD+ versus HD+ as a definitive comparison.

If the FHD+ listing applies to the Redmi 15 5G you are considering, it points to a sharper-resolution panel on paper. That is a specification-based observation, not a measured assessment of brightness, color, viewing angles or overall display quality.

Performance
Xiaomi lists the Snapdragon 6s Gen 3 for Redmi 15 5G; realme identifies the Dimensity 6300 for P4R. The cited sources do not provide a reliable independent, head-to-head performance test, so the chip names alone do not support a confident winner for gaming, multitasking or everyday speed.

Cameras
Both phones have a 50MP headline rear-camera specification. Xiaomi specifies a dual rear camera and an 8MP front camera; realme advertises a 50MP AI camera, while 91mobiles lists an 8MP front camera for P4R. Megapixel counts and marketing labels do not establish photo or video quality; that comparison requires samples taken under comparable conditions.
Which phone has better software support and protection?
Xiaomi India specifies HyperOS 2 based on Android 15 and commits to 2 years of OS updates plus 4 years of security updates for Redmi 15 5G. realme’s P4R page identifies realme UI 7.0 based on Android 16, but the cited page does not establish a matching update duration. The available information therefore does not support a like-for-like support-period verdict.

For protection, Xiaomi lists an IP64 rating. realme advertises military-grade shock resistance, which is a different kind of claim; it should not be treated as equivalent to an IP water-and-dust rating. Check the exact P4R certification if ingress protection is important to your purchase.

When 91mobiles’ comparison page was accessed in 2026, it displayed ₹21,499 for Redmi 15 and ₹20,199 for P4R—a ₹1,300 difference, with Redmi shown higher. This is a volatile comparison-page snapshot, not an official price announcement or a guaranteed current offer.

Before deciding, compare the live checkout price for the same market and sales channel, and match RAM and storage as closely as possible. Include any delivery charges or offer conditions that apply to your purchase; stock, seller and discounts can change.
Which should you buy?
Consider realme P4R 5G if
- You prioritize the larger stated battery capacity and higher rated charging speed.
- You value realme’s advertised 144Hz display and 1200-nit peak brightness, while checking the resolution and exact variant before purchase.
- Its live price is better for the memory configuration you need.
Consider Xiaomi Redmi 15 5G if
- You want Xiaomi’s India-listed 2-year OS and 4-year security-update commitment.
- The FHD+ display specification is confirmed for the India variant you are buying and resolution is a priority.
- You want one of Xiaomi India’s listed 6GB+128GB or 8GB+256GB configurations, or value its stated IP64 rating.
This is a specification-based choice, not a hands-on verdict. Check the exact regional model, memory configuration and current seller price before placing an order.
