The Ai+ Nova 2 Pro 5G has the more ambitious screen specification: it is larger, higher-resolution and rated for a higher refresh rate. The OPPO K14x 5G counters with a higher stated battery capacity and peak charging wattage. Neither spec sheet establishes which phone is faster in real use, lasts longer per charge or takes better photos. Price comparisons also depend on matching the memory variant, seller and offer.

Which phone has the better display?
On the listed specifications, the Ai+ Nova 2 Pro 5G has the advantage in screen size, resolution and refresh rate: 6.9 inches, FHD+ and 144Hz, compared with the K14x’s 6.75-inch-class HD+ LCD and up to 120Hz. That makes the Ai+ screen the stronger paper choice if detail and refresh rate are your priorities. Brightness cannot be fairly ranked from these listings because Ai+ does not provide a directly comparable brightness figure.

Which has the stronger chipset?
The Ai+ listing names a Dimensity 7100, while OPPO specifies a Dimensity 6300. The model names alone do not establish a measured speed difference: the available sources do not provide a comparable independent benchmark. Treat the chipset distinction as a specification, not proof that one phone will feel faster in every task.
Battery capacity and charging: OPPO’s listed advantage
OPPO lists a 6500mAh typical battery (6335mAh rated) and charging up to 45W; Ai+ lists 6000mAh and 33W charging. These figures give the K14x the advantage on stated capacity and maximum charging wattage, but they do not predict a particular battery runtime or charging time. OPPO’s February 2, 2026 launch announcement attributes claims of 17.6 hours of YouTube playback, 16.1 hours of Google Maps navigation and up to 12.1 hours of WhatsApp video calling to its own testing. These are manufacturer claims, not independent measurements or a head-to-head comparison. OPPO’s launch announcement

Camera specs do not settle photo quality
The K14x lists a 50MP wide camera and a 2MP monochrome camera; the Ai+ lists a 48MP primary and an 8MP secondary camera, with a Sony IMX582 named for the primary. Megapixel counts and camera count do not determine which produces better images. The cited sources do not provide a matched independent camera comparison, so a camera-quality winner is not established.

Compare like-for-like RAM and storage, then check the same retailer at the same time. The available price pages do not establish a same-seller, same-variant checkout comparison; their figures should not be treated as a definitive current price gap.

Which one should you choose?
- Choose the Ai+ Nova 2 Pro 5G on paper if a larger, sharper, higher-refresh-rate display matters most, or if you want its listed 8GB+128GB option.
- Choose the OPPO K14x 5G on paper if its higher stated battery capacity, higher maximum charging wattage, IP64 listing or 4GB memory configurations better fit your priorities.
- Do not choose on camera or real-world speed alone using these spec sheets; they do not supply a comparable independent camera test or benchmark.
- Choose by actual price only after matching variants and checkout conditions. The launch dates are not a substitute for retail availability: OPPO announced its India launch for February 10, 2026, while 91mobiles reported the Ai+ launch announcement on June 22, 2026.
