OnePlus 15 vs. iQOO 15 vs. realme GT 8 Pro: Design
| OnePlus 15 | iQOO 15 | realme GT 8 Pro | |
| Dimensions | 161.4 x 76.7 x 8.1 mm | 163.7 x 76.8 x 8.1 mm | 161.8 x 76.9 x 8.2 mm |
| Weight | 211 or 215 grams | 215 or 220 grams | 214 or 218 grams |
| Material | glass / aluminum / glass | glass / aluminum / glass | glass / aluminum / fiberglass back |
| IP Rating | IP68/IP69K (2m for 30 min) | IP68/IP69 (1.5m for 30 min) | IP68/IP69 (2m for 30 min) |
| Colors | Infinite Black, Ultra Violet, Sand Storm | Black, White, Green, Blue | Diary White, Urban Blue, Green, Aston Martin Green |
All the phones in this comparison feature a punch-hole screen at the front with symmetrical bezels on all sides. However, the iQOO 15’s camera cutout looks slightly bigger than those on the others.
Regarding the back panel design, all the phones have a distinct appearance. The OnePlus 15, for instance, has a square-shaped metallic camera module with rounded edges, along with three blacked-out modules. The iQOO 15, on the other hand, has a squircle, blacked-out camera module, along with an otherwise plain back panel. It could also arrive in a color-shifting Crimson Red color and a unique dual-colored orange and white design.
The realme GT 8 Pro seems to have the most minimal and unique back panel design. First, it features a relatively smaller circular camera module. Second, the module is replaceable as it is held in place with screws. So, those interested in customizing their smartphone can get their hands on the replaceable camera modules and DIY their way into it.
Beyond that, all the phones have similar thicknesses, weights, materials, and the best IP ratings.

| Max Video Resolution & Frame Rate | 4K@60fps | 4K@60fps | 4K@60fps |
OnePlus 15
The OnePlus 15 features a triple 50MP rear camera array (main + ultrawide + periscope telephoto), a 32MP AF front camera, 4K video up to 120 fps, and 8K video up to 30 fps. The new ISP unlocks improved HDR, multi-frame noise reduction, and the company’s new image pipeline called DetailMax. And yes, OnePlus has ended its partnership with Hasselblad, so you won’t find that on the smartphone anymore.
It’s worth noting that the periscope zoom camera on the OnePlus 15 features the smallest sensor of all, which could result in slightly inferior pictures, especially in low light.
iQOO 15
Like the OnePlus 15, the iQOO 15 also features a triple-camera setup on the back and a 32MP selfie shooter on the front. Video support goes up to 8K 30 fps, but for some odd reason, iQOO has skipped support for 4K 120 fps video. While the primary camera’s size remains the same, the iQOO 15 sports a larger telephoto sensor, which should, in theory, result in slightly better pictures.

realme GT 8 Pro
The realme GT 8 Pro features a 50MP main and 50MP ultrawide camera, but the star of the show is the 200MP periscope zoom camera. Besides having 4x the resolution, the GT 8 Pro’s coom camera features a larger aperture and sensor size. The sensor also has a minimum focusing distance of 25cm, allowing detailed tele-macro shots.
Beyond that, the phone supports 8K 30 fps video and 4K 120 fps video. This year, realme has partnered with Ricoh Imaging for tuning the imaging. As part of the collaboration, the smartphone features a GR Mode with quick shutter response, support for two full-frame-equivalent focal lengths supported via cropping, and five classic Ricoh GR Tones built into the camera app.
