Pick the 13 Pro+ if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are weight, water resistance.
Pick the Xiaomi 15 Ultra if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. Its strongest claims are antutu, ram, battery capacity, among others.
