The Ai+ Nova 2 Pro 5G has the stronger display specifications on paper: it is larger, higher-resolution and rated for a higher refresh rate. The OPPO K14x 5G lists a larger battery capacity and higher peak wired-charging wattage. Price depends on the exact RAM and storage variant, seller and offers, so the available snapshots do not establish a definitive like-for-like price gap.

Which phone has the better display?
The Ai+ Nova 2 Pro 5G has the advantage in the published display specifications: its 6.9-inch panel is larger than the K14x’s 6.75-inch-class screen, and its FHD+ resolution is higher than the OPPO’s HD+ resolution. Ai+ also lists 144Hz refresh, compared with OPPO’s maximum 120Hz. Those figures favor Ai+ for buyers prioritizing screen size, detail and refresh rate. They do not establish which screen looks brighter: the cited Ai+ listing does not give a directly comparable brightness measurement.
Chipset, battery and charging: what the specifications show
Chipset
Ai+ lists the Dimensity 7100, while OPPO lists the Dimensity 6300. The model numbers alone do not establish real-world speed, and the sources cited here do not provide a matched independent benchmark. Treat this as a difference in listed hardware, not proof that one phone is faster in everyday use or games.
Battery and charging
OPPO lists the higher battery capacity and peak charging wattage: 6500mAh typical capacity and up to 45W, against Ai+’s 6000mAh and 33W. Capacity and maximum wattage do not by themselves predict how long a phone will last or how quickly it will charge under actual conditions.

Camera, memory and software differences

What are the prices in India?
Price snapshots vary by source and do not prove a same-seller, same-variant checkout comparison. At the time the Ai+ manufacturer listing was accessed on October 7, 2026, it displayed ₹17,999 for 6GB+128GB and ₹19,999 for 8GB+128GB; the page also showed the phone as sold out. Those are listing figures, not confirmation of current stock or a guaranteed sale price. Check the Ai+ listing.
A Gadgets Now comparison page, crawled during the week before October 7, 2026, displayed ₹17,499 for the OPPO K14x and ₹19,499 for the Ai+ Nova 2 Pro 5G. It does not establish matching RAM/storage variants, a common seller or checkout offer terms, so the ₹2,000 difference should not be treated as a definitive like-for-like gap.

Which one should you choose?
- Choose the Ai+ Nova 2 Pro 5G if the larger, sharper, higher-refresh-rate display is your priority, or you want the listed 8GB+128GB option.
- Choose the OPPO K14x 5G if its larger stated battery capacity or higher listed peak charging wattage better fits your priorities.

OPPO announced the K14x for India on February 10, 2026. Independent coverage reported the Ai+ Nova 2 Pro launch announcement on June 22, 2026; an announcement date is not, by itself, confirmation of retail availability. See the 91mobiles launch coverage.
