The realme P4 5G pairs an AMOLED display with faster 80W charging, while the Xiaomi Redmi 15 5G has a larger LCD screen and a stated software-update schedule. Both list a 7,000mAh typical battery. For price, compare the same RAM and storage configuration and confirm the current listing before buying.

Which display is better?
The P4 5G is the choice to consider if you specifically want AMOLED: realme lists a 6.77-inch, 1080 × 2392 panel with a maximum 144Hz refresh rate. Xiaomi lists a larger 6.9-inch FHD+ LCD on the Redmi 15 5G, also with up to 144Hz. In short, Redmi offers more screen area, while P4 offers the different panel technology. The shared 144Hz maximum alone does not establish which screen looks better in use.

Do their chipsets show which phone is faster?
The Redmi 15 5G uses Qualcomm’s Snapdragon 6s Gen 3; the P4 5G uses MediaTek’s Dimensity 7400 Ultra. Those names identify different chipsets, but the specifications cited here are not comparable performance tests. They do not establish which phone is faster in games, apps or everyday use.
Battery capacity and charging: what changes?
Both manufacturers list a 7,000mAh typical battery, so capacity is equal on paper. Charging is not: Xiaomi specifies 33W wired charging and 18W reverse charging for the Redmi, while realme specifies 80W wired charging for the P4 and says an 80W adapter is included. These figures do not show how long either phone lasts or how quickly it charges in a controlled real-world comparison.

How do the cameras compare?
Xiaomi lists a 50MP AI dual rear camera and an 8MP front camera. realme specifies a 50MP main rear camera, an 8MP wide-angle camera and a 16MP front camera; it also lists rear video capture up to 4K at 30fps. The specifications do not establish photo or video quality, and megapixel counts alone are not a reliable way to rank the cameras.
Software and update support
Both phones are listed with Android 15-based software: HyperOS 2 on the Redmi 15 5G and realme UI 6.0 on the P4 5G. Xiaomi states a commitment of “2 years of OS + 4 years of security updates.” The cited realme specification page does not give an update-support duration, so it is not possible to compare the two commitments from these listings.

Configurations and price difference in India
Both models have 6GB and 8GB RAM options and 128GB and 256GB storage options in their listed configurations. Xiaomi lists 6GB+128GB and 8GB+256GB, with LPDDR4X RAM and UFS 2.2 storage. realme lists 6GB or 8GB RAM with 128GB or 256GB storage, using LPDDR4X RAM and UFS 3.1 storage.
A 91mobiles comparison page displayed ₹21,499 for the Xiaomi Redmi 15 and ₹20,999 for the realme P4, a ₹500 difference in that page’s snapshot. The page marked the P4 out of stock and does not establish that the displayed prices were for matching configurations or included the same discounts. Treat these as secondary-site displayed prices, not live checkout quotes: confirm availability and compare the exact RAM/storage variants at retailers before ordering.

Which one should you choose?
- Consider the realme P4 5G if AMOLED is your priority or you want the higher specified wired-charging rate.
- Consider the Xiaomi Redmi 15 5G if you prefer the larger listed screen or want a manufacturer-stated OS and security update timetable.
- Check the exact price and configuration before deciding: the listed RAM/storage combinations are not identical across every tier, and the cited price snapshot is not a live, matched-variant quote.
Neither chipset names nor battery capacity settle which phone performs better or lasts longer in practice. The available specifications do not provide controlled performance, camera or runtime results, so those questions remain open.
