The realme P4x 5G is the spec-led pick for a larger stated battery, higher rated charging wattage and faster listed display refresh rate. Nothing Phone (4b) has a slightly larger Super AMOLED screen, an ultrawide rear camera and a higher-resolution front camera in the comparison data. A 91mobiles snapshot lists the P4x at ₹26,999 and the Phone (4b) at ₹35,999 on Flipkart—a ₹9,000 gap, not a guaranteed current price.

Which phone has the better display?
It depends on what you value. The Phone (4b) has the slightly larger, 6.77-inch Super AMOLED panel; the P4x is listed with a 6.72-inch LCD and a higher 144Hz refresh rate versus 120Hz. The refresh-rate number describes how often the display can update, not overall display quality. Panel type, content and personal preference matter too.

Which phone has the better battery and charging?
The P4x leads on the stated figures: 7000mAh and 45W charging, compared with 6000mAh and 33W for the Phone (4b). Capacity and charging wattage do not establish how long either phone lasts or how quickly it charges in everyday use. No equal-condition battery-life or charging comparison is established here.
How do their cameras differ?
Both phones are listed with a 50MP main rear camera. The P4x adds a 2MP mono camera, while the Phone (4b) is listed with an 8MP ultrawide camera, which provides a different framing option. Their listed front cameras are 8MP and 16MP respectively. These resolution figures and camera configurations do not establish which phone takes better photos or selfies; no controlled photo comparison is available.
Does the chipset make one phone faster?
The comparison lists a MediaTek Dimensity 7400 Ultra in the P4x and a Snapdragon 6 Gen 4 in the Phone (4b). It gives peak frequencies of 2.6GHz and up to 2.3GHz respectively, but clock speed alone cannot determine overall performance, gaming capability or sustained speed. A fair performance verdict would require comparable independent tests.
