The realme 15x 5G is the charging-speed pick, with a listed 60W charge rate; the realme P4R 5G has the larger stated battery, at 8000mAh. Both are listed with a Dimensity 6300 chip and displays advertised at up to 144Hz. The better buy depends on your priorities and the live price of an equivalent memory-and-storage variant in India.

Specifications are manufacturer-published claims, not independent comparative tests. A matching chipset name does not establish identical real-world performance, and camera megapixels alone do not show which phone takes better photos.
How the listed prices compare in India
The available figures do not establish a current, like-for-like price difference. realme India’s store showed the 15x at ₹27,999 for a selected 8GB+256GB configuration when accessed. realme’s newsroom announced the P4R at a starting price of ₹16,999, while a separate official store comparison listing displayed ₹20,999 without establishing the matching configuration or promotion terms. These figures come from different price contexts and should not be treated as a direct price gap. realme 15x official store listing; realme P4R launch announcement; realme store comparison listing.

Which model suits your priorities?
Choose the 15x if charging wattage matters most
The 15x lists 60W charging, compared with the P4R’s 45W. Wattage alone does not establish how long either phone takes to charge, so treat this as a specification difference rather than a measured charging-time result.
Choose the P4R if stated battery capacity matters most
The P4R lists an 8000mAh battery, while the 15x lists 7000mAh typical capacity. The capacity figures do not establish which phone lasts longer in everyday use; runtime depends on more than battery size.
Look beyond refresh rate when comparing screens
Both are advertised with up to 144Hz refresh and 1200-nit brightness. The 15x page specifies a 6.8-inch HD+ panel at 1570 × 720, but comparable P4R resolution information is not established in the cited material. Do not assume equal sharpness from the shared refresh-rate claim.
Do not treat dynamic RAM as installed RAM
The 15x is listed with 6GB or 8GB RAM and up to 256GB storage. The P4R page highlights up to 14GB dynamic RAM and 256GB storage, but its exact base configurations are not established here. Dynamic RAM uses software allocation and is not a substitute for physical RAM; confirm the installed memory on the exact variant before comparing.

Compare camera quality using sample-based evidence
The 15x lists 50MP rear and front cameras, and the P4R highlights a 50MP AI camera. Those labels do not establish image quality or make the camera systems directly comparable. Use independent photo and video samples for the conditions that matter to you.
Account for the listed software versions
The product pages accessed on 7 October 2026 list the 15x with realme UI 6.0 based on Android 15 and the P4R with realme UI 7.0 based on Android 16. These are page-listed versions; future update availability and support duration are not established by these specifications.

On listed specifications, the P4R offers greater stated battery capacity, while the 15x offers higher charging wattage and a clearly specified HD+ display. Both share a listed chipset and headline refresh rate, but the available information is insufficient to declare an overall winner on performance, screen sharpness, camera quality, or battery life. Choose according to the feature you value, then compare current prices for matching RAM and storage in India.
