What the specification differences mean
Display: sharper on realme, slightly larger on OnePlus
The P4x pairs FHD+ resolution with a 144Hz refresh rate, while the N6x listing specifies HD+ resolution and 120Hz. That makes the realme the more compelling specification choice for fine detail and smoother supported motion. The OnePlus screen is 0.08 inches larger diagonally. Panel figures alone do not establish real-world brightness, color or viewing quality.
Performance: the listed chipset favors the P4x
The P4x lists a MediaTek Dimensity 7400 Ultra 5G, compared with the N6x’s Dimensity 6360 Apex. The names and product positioning favor the P4x on paper, but they are not a substitute for independent, comparable performance testing. OnePlus also advertises its own fluency-test results: 48 months for the 4GB+128GB N6x and 36 months for the 4GB+64GB version. Those are OnePlus test-lab claims, not a guarantee of lag-free use.

Cameras: more megapixels, not a proven photo win
The comparison lists a 50MP main plus 2MP monochrome rear setup and an 8MP front camera for realme; it lists a 13MP rear and 5MP front camera for OnePlus. These are resolution differences, not verified head-to-head image-quality results. Sensor, lens, image processing and shooting conditions matter too, and no controlled camera comparison is established here.
Battery and charging: same stated capacity class, different charging rate
Both phones are listed in the 7000mAh battery class. The P4x’s stated 45W charging is faster than the N6x’s 15W listing. Capacity does not tell you how long a charge lasts: screen, network, software and usage all affect endurance. OnePlus says the N6x can provide up to 2.5 days per charge based on OnePlus Test Lab results, and notes that actual battery life varies with environment, network, apps, usage and device condition.
Storage: compare like-for-like variants
The comparison shows 128GB for the P4x, while OnePlus describes 64GB and 128GB N6x options. realme also promotes higher memory/storage configurations. Confirm the RAM and storage combination attached to each live listing before judging either price; a lower price may be for a different configuration.

Which phone should you buy?
Choose the realme P4x 5G if
- You want the higher stated display resolution and refresh rate.
- You prioritize the P4x’s chipset positioning, listed camera resolutions or faster 45W charging.
- The exact storage configuration and final price suit your needs.
Consider the OnePlus N6x 5G if
- You prefer its slightly larger display or OnePlus software experience.
- The lower observed retailer listing remains available for the same RAM/storage class you want.
- You value OnePlus’s stated durability ratings, while recognizing those claims do not establish comparative durability.
This is a specification-based recommendation, not a hands-on or controlled test. realme announced the P4x on November 26, 2025, with a planned December 4, 2025 debut; OnePlus dates the N6x launch to July 31, 2026. For each phone, confirm current availability, software version and support terms for your region before buying.
