A few weeks ago, this was a price fight. The iQOO 15 was the cheaper flagship, the OnePlus 15 the pricier one. That version is dead. As of 1 November 2026, Gadgets360 lists the OnePlus 15 from Rs 84,999 on Amazon, and the iQOO 15 from Rs 85,999. 91mobiles agrees, and puts both 16GB and 512GB models at Rs 93,999. The gap is Rs 1,000: a rounding error, not a gap.
So forget the old framing. OnePlus 15 vs iQOO 15 is now a straight question: two phones, same Snapdragon 8 Elite Gen 5 chip, same RAM and storage choices, same triple 50MP camera idea. Which one deserves the money? Short answer: the iQOO 15, narrowly, because it is the phone you will still be happy with in 2030. The OnePlus 15 is the better charger. The iQOO 15 is the better keeper.
The price gap that vanished
Both phones started life near Rs 73,000, and both have climbed since. Beebom puts the OnePlus 15 rise at Rs 12,000 over its launch price, and our OnePlus 15 review reached the same conclusion: a very good phone priced into the wrong fight. Smartprix’s launch timeline, quoted in our iQOO 15 review, has the iQOO 15 launching in India on 26 November 2025 at Rs 72,999 for 12GB and 256GB. Digit, on 29 October 2026, still calls Rs 85,999 the official iQOO price, with up to Rs 11,899 back via an Amazon Pay ICICI Bank card. Gizbot, on 30 October, found the OnePlus 15 at Rs 84,999 against an Rs 89,999 MRP, with Prime members able to reach roughly Rs 80,750 through cashback.
Bank offers change the maths without changing the phones. On list price, OnePlus wins by Rs 1,000. With the right card, either can be cheaper on a given day. Price winner: OnePlus, by a nose.
Cameras first, because that is where they split
The iQOO 15 uses a Sony IMX921 main sensor with stabilisation, a periscope telephoto at 3x optical zoom, and an ultrawide, per Digit and Android Central. TechWiser lists the periscope sensor at a relatively large 1/1.95 inch, which helps in dim light. Gadgets360 calls the improved cameras a plus, then flags inconsistent low-light portraits as a minus. Daylight shots please almost anyone, and the zoom is useful where stepping closer is not an option.
The OnePlus 15 uses a Sony IMX906 main sensor, a periscope telephoto at 3.5x optical zoom, and an ultrawide covering 116 degrees, per Digit and GSMArena. It reaches further, and that reach is real for stadium seats. But reach is not the whole camera. OnePlus dropped Hasselblad branding and asked its own DetailMax engine to carry the colour story, per GSMArena. 91mobiles scores it at 8.4 out of 10 and says its cameras lag behind the OPPO, iPhone and Vivo flagships. That stings because Vivo tunes the iQOO cameras. Camera winner: iQOO, narrowly, on sensor size and tuning.
A sharper screen, or a faster one
The trade here is clean. The iQOO 15 has a 6.85-inch Samsung M14 LTPO AMOLED panel at 2K resolution, 3168 by 1440 pixels, running at 144Hz, per Gadgets360, Beebom and Digit. Text looks razor sharp, and outdoor visibility is not something you think about.
The OnePlus 15 has a 6.78-inch LTPO AMOLED panel at 1.5K resolution, 1272 by 2772 pixels, running at 165Hz, per Gadgets360, Smartprix and GSMArena. Gadgets360 lists “165Hz is not worth the lower display resolution” among the OnePlus cons, and that criticism lands. Nobody’s eyes can tell 144Hz from 165Hz in normal use. Everybody’s eyes can tell a sharper panel when reading small text. Gadgets360 does flag one iQOO flaw: a noticeably thick bottom bezel. After a day of use, you stop seeing it. Display winner: iQOO, on resolution.
Speed is a tie. Gaming is not quite one
Raw performance is a dead heat. Both run Qualcomm’s Snapdragon 8 Elite Gen 5 with up to 16GB of LPDDR5X RAM and up to 512GB of UFS 4.1 storage, per Gadgets360 and HT Tech. Either will run anything on the Play Store for years. If a benchmark table decides it for you, buy the cheaper one on the day.
Gaming is where tuning diverges. The iQOO 15 adds a dedicated Q3 gaming chip, per Beebom, and Beebom’s tests put it at roughly 119 frames per second in BGMI and 120 in Call of Duty Mobile. The OnePlus 15 counters with a 165Hz ceiling, per Gadgets360. Very few games sustain 165 frames, so the OnePlus ceiling is mostly theoretical, while iQOO frame stability is something you feel in a long BGMI session. Gaming goes to iQOO, narrowly, for consistency.
Battery is where OnePlus fights back
This is the OnePlus round, and it is not close on paper. The OnePlus 15 carries a 7,300mAh silicon-carbon battery with 120W wired charging and 50W wireless charging, per Gadgets360 and 91mobiles. GadgetsNow lists 50 percent in 15 minutes on the wire. The iQOO 15 carries a 7,000mAh battery with 100W wired charging and 40W wireless charging, per Gadgets360 and Digit. Only the OnePlus turns a flat battery into a short problem.
Weight does not split them: GSMArena puts the OnePlus 15 at 211 grams, FoneArena puts the iQOO 15 at 216.2 to 220 grams, both IP68 and IP69. Battery winner: OnePlus, clearly.
The update promise settles it
Software is the decider. The iQOO 15 runs OriginOS 6 on Android 16, and FoneArena and Beebom both list five Android OS updates and seven years of security updates. Gadgets360 calls OriginOS cleaner than iQOO’s older skins, which used to be the brand’s weak spot.
The OnePlus 15 runs OxygenOS 16 on Android 16, per Smartprix and 91mobiles, and GadgetsNow lists four years of OS updates and six years of security updates. OxygenOS still has the cleaner reputation, and for buyers who dislike clutter it remains a reason to pick OnePlus. Reputation does not add a year of updates, though. Software winner: iQOO, on longevity, with OnePlus winning on polish.
OnePlus 15 vs iQOO 15: the verdict
No fence-sitting. Price: OnePlus, by Rs 1,000. Display, gaming, cameras, software: iQOO. Battery and charging: OnePlus, clearly.
The overall winner is the iQOO 15, four rounds to two. The rounds it wins are the ones you live with every day and for the longest time: the screen, the camera, and the update promise that decides whether the phone still feels current in 2030. The OnePlus rounds are narrower: a Rs 1,000 price edge a bank offer can erase, and a battery lead for people who run their phones flat daily.
Buy the iQOO 15 if you game daily, if you notice screen sharpness, if portraits matter, or if you plan to keep the phone for four or five years. Buy the OnePlus 15 if the 7,300mAh battery and 120W charging shape your day, if OxygenOS is why you stayed with OnePlus, or if you find it near Rs 81,000. Do not buy either at full price without checking our Realme GT 8 Pro vs OnePlus 15 comparison first: the GT 8 Pro, at Rs 72,999, remains the value spoiler for this price band. Between these two, the choice is made.
