Used the OnePlus 13s for a week, and man what a letdown. The phone looks great, feels premium, but snapdragon chipset is just plain dumb. It struggles with heat, background apps reload constantly, and gaming performance just heats up the price. Oxygen OS feels smooth until you multitask - then it turns into a lag fest. Battery life dips fast too, probably because of underpowered chip. For something marketed as flagship, it acts more like a confused mid ranger.
