Final Verdict
The Apple iPhone Duo looks like the more ambitious device here, mainly because of that much larger 7.6-inch 120Hz display and the bigger 5000mAh battery. If you watch a lot of video, read, multitask, or simply want more screen space, it should feel noticeably roomier than the OnePlus. It is the phone that seems built around a bigger canvas rather than just raw spec-sheet balance.
The OnePlus Ace 4 Pro fights back with more RAM, which may appeal if you keep lots of apps open or care about heavier multitasking. Its 6.78-inch 120Hz display is still large, just more conventional, and the Qualcomm platform should make it a familiar pick for Android users.
Based on these specs alone, the iPhone Duo is the more interesting choice for people who value screen size and battery headroom. The OnePlus makes more sense if you prefer Android, want extra RAM, and don’t need such a massive display.
