Last year the OnePlus 13T hit that rare sweet spot for compact phone fans: comfort, proper flagship performance, and battery that didn’t feel like a compromise. In this review, I put the new OnePlus 15T through the full real-world experience to see if it keeps that magic — and honestly, it’s shaping up to be a dream phone for small-screen lovers. I cover the refined design (my personal favourite colour is the “healing white chocolate” because a clean white phone is just irresistible), the super-slim symmetrical bezels, and the 6.32-inch flat 1.5K LTPS panel with a crazy 165Hz refresh rate. I also dive deep into gaming and thermals with controlled tests, where the Snapdragon 8 Elite Gen 5 plus the big VC cooling and gaming chips deliver near-perfect frame rates in titles like Honor of Kings, Peacekeeper Elite, Delta Force, and Genshin Impact — with impressively low power draw and strong temperature control for a compact device. Then there’s the real headline: OnePlus squeezing a massive 7500mAh battery into this size, plus 100W wired and 50W wireless charging. I wrap up with the camera upgrades (50MP main + 3.5x periscope telephoto), why I prefer telephoto over ultra-wide for daily use, and the software extras like ColorOS 16 features and Mac connectivity through Oppo Connect — plus the China starting price and the rough UK conversion.
