I’m not exactly sure when it began, but the smartphone world quietly decided that if you want top-tier performance, long battery life, and a proper flagship camera, you have to live with a huge 6.8-inch slab. In this video, I unbox and review the OnePlus 15T and show why it feels like OnePlus finally listened to small phone fans like me. You’re getting a 6.32-inch flat OLED with ultra-slim 1.1mm bezels, a compact 71.82mm width, and about 190g weight (around 208g with a case and protector) — so one-handed typing and pulling down notifications is actually easy again. I go deep on the stuff that matters: Snapdragon 8 Elite Gen 5 performance (Geekbench 6 is right up there with today’s Android flagships), real gaming stability at max settings, and thermals that stay within expectations for a compact body. But the real “small screen demon king” moment is the 7500mAh battery — I finished my day with 60% left after nearly 5.5 hours of screen-on time, and for my usage it can easily stretch to two days. Then you’ve still got 100W wired and 50W wireless charging, plus a genuinely surprising camera setup for this size, including a 50MP periscope with 3.5x optical zoom that stays sharp even at 7x lossless.
