iQOO 16 vs OnePlus 16: Gaming Flagship Comparison & Price

Build and design

The iQOO is a gaming flagship at 6.85 inches, with a 2K Samsung M16 display, an 8,500 sq mm vapour chamber and IP68/IP69 ratings. The OnePlus is a gaming flagship at 6.78 inches, with a 165Hz interface display, 185Hz in games, bypass charging and dedicated P4, G3 and T3 chips for display, eSports and touch. Both phones feel premium, but the iQOO is more display-focused, while the OnePlus is more touch- and charging-focused.

If you want the sharpest display and a dedicated gaming chip, the iQOO wins on paper. If you want the biggest battery and bypass charging for long sessions, the OnePlus wins. For most gamers, the OnePlus is the safer choice on battery, unless display resolution is a priority.

Display and benchmarks

The iQOO offers a 6.85-inch Samsung M16 AMOLED at 3168 x 1440 with up to 165Hz, up to 2,800 nits HBM and 10,000 nits peak local brightness. The OnePlus offers a 6.78-inch LTPO OLED at 1272 x 2772 with 165Hz interface and 185Hz in games. For gaming, the iQOO's 2K resolution is sharper, while the OnePlus's 185Hz in games is smoother on paper. For everyday use, both displays are flagship-grade, with the iQOO winning on resolution and the OnePlus winning on game refresh rate.

On benchmarks, both phones use Snapdragon 8 Elite Extreme Gen 6, so no chip winner is claimed — a controlled side-by-side benchmark between these two phones was not reviewed. The iQOO adds a Q4 gaming chip, while the OnePlus adds P4, G3 and T3 chips, so any real-world difference would come from cooling and software, not from a generational gap. For sustained gaming, the iQOO's larger vapour chamber should help, while the OnePlus's bypass charging should help for long plugged-in sessions.

Cameras and video

The iQOO offers triple 50MP cameras — a main at 1/1.3-inch with OIS, a periscope at 3x with OIS and an ultrawide — plus a 32MP front camera and 8K video. The OnePlus offers a 200MP main at 1/1.4-inch f/1.6 with OIS, a 50MP 3x periscope at 1/1.95-inch f/2.6 and a 50MP ultrawide, plus a 50MP front camera. On paper, the OnePlus wins on main megapixels and front camera, while the iQOO wins on periscope sensor size. For everyday photos at 1x, both should be close, despite the megapixel gap.

No controlled side-by-side camera test between these two phones was reviewed, so no photo winner is claimed beyond the hardware gap. If you shoot zoom often, both offer 3x periscope, so the difference is sensor, not zoom range. If you shoot selfies, the OnePlus is stronger on paper at 50MP versus 32MP. For video, both offer flagship video, with the iQOO's 8K noted in its specs.

Battery, software and price

Battery is where the OnePlus wins on paper, with 9,000mAh and 100W wired, 50W wireless and 27W reverse charging, with 80% in 37 minutes claimed, versus the iQOO's 8,400mAh with 100W wired and 40W wireless charging. For most gamers, the OnePlus will last longer on paper, while the iQOO's battery is still flagship-grade. Charging is faster on the OnePlus on paper for wireless and reverse, though real-world charging should be checked in reviews.

Software is OriginOS 7 on Android 17 for the iQOO, with IP68/IP69, while the OnePlus runs ColorOS 17. In China, both start at CNY 5,999 for 12GB/256GB and rise to CNY 8,499 for 16GB/1TB — an identical China price range on paper, though storage tiers differ in detail. In the US and Europe, neither is officially sold, so do not treat a China price or a conversion as a US or Europe price.

Verdict

Buy the OnePlus 16 if you want the biggest battery at 9,000mAh and bypass charging for long gaming sessions, in China from CNY 5,999. Buy the iQOO 16 if you want a 2K 165Hz display and a dedicated Q4 gaming chip, in China from CNY 5,999. For US and Europe buyers, neither is officially sold today — both are wait-and-see imports.
