The Ai+ Nova 2 Ultra 5G is more appealing on paper for its reported AMOLED screen and 8MP ultrawide camera. Their Dimensity 7400-family chips look closely matched by listed specifications, but the available evidence does not establish a real-world performance winner.

realme P4x vs Ai+ Nova 2 Ultra 5G: key specs
This comparison is for the India-market phones. Specifications below combine realme’s official P4x page with secondary comparison listings and April 2026 launch coverage for the Ai+ model. Where those sources disagree or an official Ai+ specification is not established, the table says so rather than treating a reported figure as certain.

Which phone has the better display?
Choose the Nova 2 Ultra for AMOLED
The Nova 2 Ultra appears to have the display advantage for contrast and deep blacks because launch coverage describes a 1.5K AMOLED panel. That coverage also reports 2,500-nit peak brightness. These are reported specifications, not a verified independent brightness measurement.

Choose the P4x for its stated 144Hz LCD
realme specifies a 144Hz LCD and up to 1,000-nit peak brightness for the P4x. A high refresh rate can make supported scrolling and animation appear smoother, but it does not make an LCD equivalent to AMOLED in contrast. Secondary comparisons differ on P4x resolution, so consult the manufacturer’s page rather than relying on a mismatched listing.
Nova refresh-rate claims are inconsistent: 91mobiles lists 120Hz, while April 2026 launch coverage and another comparison listing report 144Hz. Confirm the panel details for the exact model before buying if refresh rate is decisive. See the 91mobiles comparison, Gadgets 360 comparison, and Business Remedies’ April 2026 launch coverage.
Battery and charging: P4x has the listed capacity advantage
The P4x’s 7,000mAh battery is larger than the 6,000mAh capacity reported for the Nova 2 Ultra. realme also specifies 45W charging for the P4x; comparison coverage lists 18W for the Ai+ phone, but that figure should be confirmed against an official Ai+ specification before treating it as definitive.

No controlled side-by-side battery or charging test is established here, so usage, screen settings, network conditions, and software can affect the result.
Camera comparison: ultrawide flexibility versus untested image quality
On published camera specifications, the Nova 2 Ultra offers a more versatile rear setup: a 50MP main camera reported with optical image stabilization (OIS), plus an 8MP ultrawide. The P4x has a 50MP main camera and a 2MP secondary rear camera in comparison listings. The Nova is also listed with a 13MP front camera versus 8MP for the P4x.
Those numbers do not prove which phone takes better photos or video. A higher megapixel count does not by itself determine image quality, and no controlled camera comparison is established here. realme lists 4K video capability for the P4x on its official specification page; the cited Nova launch coverage does not establish an equivalent video specification.

Performance: similar chip family, no proven winner
The P4x is listed with a Dimensity 7400 Ultra, while the Nova 2 Ultra is reported with a Dimensity 7400. 91mobiles lists both with an octa-core configuration up to 2.6GHz and a Mali-G615 MC2 GPU. Those shared listed details suggest that chipset names alone are not enough to call one phone faster; software, cooling, memory configuration, and sustained workloads also matter.
realme’s P4x product page claims a score of “780,000+” on AnTuTu. This is a manufacturer claim, not an independent side-by-side result, and the reviewed comparison evidence does not provide a comparable Nova 2 Ultra score. It should not be used as proof that the P4x outperforms the Ai+ phone. The P4x page also lists UFS 3.1 storage, which may matter to buyers comparing particular storage variants.

Price difference: check current India listings
There is no settled current price in the reviewed comparison sources. 91mobiles showed ₹21,939 for the P4x on Amazon and ₹20,999 for the Ai+ Nova 2 Ultra on Flipkart. Gadgets 360 and other indexed comparison data surfaced ₹21,999 for each, with the Ai+ marked out of stock. These are observed comparison-page figures, not guaranteed live offers. April 2026 launch coverage reported a ₹16,999 starting price for the Nova 2 Ultra; that is launch-era context, not its confirmed current selling price.
Before comparing totals, check the live retailer pages for the exact RAM and storage variant, seller, stock, bank or exchange offers, and delivery location. The listed difference can change with discounts and availability.

Pick the symptom - the matching free tool is one click away.
Which phone should you buy?
- Pick the realme P4x if you prioritize a larger stated battery, 45W charging, a 144Hz display specification from the manufacturer, or UFS 3.1 storage.
- Consider the Ai+ Nova 2 Ultra if AMOLED is more important to you, or you want the reported 8MP ultrawide and OIS-equipped main camera.
- Do not choose on chipset or price alone without checking the exact variant and current listing: comparable performance results are absent, and observed prices and availability differ.
For the P4x’s official product specifications, use realme India. For the Nova 2 Ultra’s reported April 2026 launch configuration, consult Business Remedies, while treating launch and comparison listings as secondary sources.
