OnePlus 15 – The Ultimate 2025 Smartphone? Full Specs & Expert Review

 Introduction & Context

The OnePlus 15 arrives as OnePlus’s flagship for 2025, marking a bold evolution in the brand’s design language and hardware ambitions. It blends top-tier performance, an extra-large battery, and a rugged premium build, all while maintaining OnePlus’s tradition of competitive pricing in the flagship arena.

Interestingly, OnePlus jumped directly from the OnePlus 13 to the 15, bypassing “14” altogether. This naming shift reinforces the company’s message: this generation is meant to feel like a major leap forward.
