Design and Build Quality

All three phones use glass and aluminum frames with punch-hole displays and slim, even bezels. The OnePlus 15 goes for a premium square metallic camera island, while iQOO 15 opts for a simple squircle module with special Crimson Red and dual-tone finishes. realme GT 8 Pro feels the most experimental, thanks to its smaller circular camera ring that is actually replaceable, letting you swap modules for a more customized look.

For endurance, the OnePlus 15 leads the way, with a 7,300mAh Si/C battery and support for 120W wired fast charging, plus 50W wireless, easily targeting multi-day light usage.
