In this video I’m reviewing the OnePlus 15T, and honestly it’s one of those phones that makes you feel like the rules of physics don’t apply anymore. You’re getting a compact 6.32-inch body, but it’s packing a massive 7500mAh Glacier Battery, a flat flagship-level display that goes all the way up to 165Hz, and even a 3.5x periscope telephoto camera—stuff that compact phones usually have to compromise on. I also go into the in-hand feel (71.8mm wide, 194g, balanced 50/50 weight), the minimal camera bump, and why the ultra-slim 1.1mm bezels make it feel so immersive day to day. Battery is the big headline here, so I ran proper tests at 200 nits and 50% volume. After 4.5 hours mixed use, it only drained 39%, which works out to nearly 12 hours screen-on time for medium to heavy use—on a small phone. Then I pushed gaming hard: 144FPS in Honor of Kings and native 165FPS in PUBG Mobile and Delta Force, with very stable frame rates thanks to the Snapdragon 8 Elite Gen 5 and the Ice Core cooling setup. I also cover charging (100W wired, 50W wireless) and wrap up with pricing, which works out to roughly £469 in the UK for the base model (China price conversion).
