For buyers in India, the realme P4x has the stronger listed specifications: a higher-tier chipset, a display refresh rate of up to 144Hz instead of 120Hz, and a 7000mAh typical battery instead of 6000mAh. Both phones have a 6.72-inch FHD+ LCD and list 45W charging. The practical buying complication is availability: realme’s India store marks the P3x unavailable/discontinued and recommends the P4x.

Which is better: realme P3x or P4x?
On the published specifications, the P4x is the more capable package for buyers prioritising the chipset, refresh-rate ceiling, or battery capacity. Its Dimensity 7400 Ultra is the higher-tier listed processor, and its screen supports up to 144Hz compared with the P3x’s 120Hz. The P4x also lists 1000mAh more typical battery capacity.

Those figures do not establish a precise real-world performance gain, longer screen-on time, or better sustained gaming. Those outcomes depend on testing and usage conditions not established by the specifications pages.

Display: higher refresh rate, same panel class
Both phones list a 6.72-inch FHD+ LCD, so the P4x is not an AMOLED upgrade. Its listed maximum refresh rate is 144Hz versus 120Hz on the P3x, which gives it the higher specification ceiling for supported motion. The pages also list peak brightness of 1000 nits for the P4x and 950 nits for the P3x; these listed figures alone do not establish comparative outdoor visibility.
Battery and charging: more capacity on the P4x
realme lists the P3x at 6000mAh typical capacity (5860mAh minimum) and the P4x at 7000mAh typical capacity (6830mAh rated). The P4x therefore has the larger listed battery, while both list 45W charging. Capacity and charging specifications do not prove how long either phone lasts in everyday use or how quickly it charges under particular conditions.
Cameras: compare the hardware, not just megapixels
The listed rear setups are a 50MP main plus 2MP portrait camera on the P3x, and a 50MP main plus 2MP monochrome camera on the P4x. The P4x page also lists an 8MP front camera and rear video recording up to 4K at 30fps. Megapixel counts and camera labels do not establish which phone takes better photos; the available specifications are not a comparative image-quality test.

The P3x specifications list 6GB or 8GB RAM with 128GB storage. The P4x page lists storage up to 256GB, but configurations can vary by region and variant. Compare the exact retail variant before buying, and do not treat dynamic RAM, where offered, as additional physical memory.

realme lists realme UI 6.0 based on Android 15 for the P3x and realme UI 6.0 for the P4x. The cited P4x specifications do not establish an update-duration commitment, so these details are not enough to compare how many years of software support either model will receive.

A current price gap cannot be established from the available official India listings. realme’s P3x store page displays ₹13,999 against an MRP of ₹16,999 for the 6GB+128GB variant, but marks the product unavailable/discontinued. That displayed price should not be treated as a live offer. No official P4x price was verified here, so calculating a difference would be misleading.

Before comparing offers, check prices for equivalent RAM and storage configurations, and separate the seller’s base price from bank or exchange discounts. The P3x store status is realme’s own listing status; it does not prove that every third-party seller has no remaining stock. Third-party stock and warranty conditions have not been verified.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Should you buy the P4x as an upgrade?
The P4x is the more straightforward choice if you want the stronger listed chipset, higher refresh-rate ceiling, or larger stated battery, and can confirm its current price and seller terms. Consider a P3x only if you find a remaining unit at a suitable price and can verify the exact variant, warranty, and seller. Because realme marks it discontinued/unavailable on its India store, availability may be less predictable.
Neither model’s published specifications settle battery endurance, camera quality, thermal behaviour, sustained gaming performance, or long-term software support. Treat those as unknowns rather than assuming the spec-sheet advantage guarantees a better experience.
