InnoReviews verdict

This one is close to a dead heat: OnePlus 13 scores 77 against 75.9 for Xiaomi 15 Ultra. Pick by the categories that matter to you — OnePlus 13 edges ahead in display and battery, or by price.

Editor's note

Same Snapdragon 8 Elite, two philosophies. The OnePlus 13 is the battery-and-speed play: 6,000mAh, 100W charging and a brighter panel for $600 less. The Xiaomi 15 Ultra is the camera play: its 200MP periscope and 4.3x optics are a class above the OnePlus 3x unit, and that is the whole argument. Unless the camera is the reason you are upgrading, the OnePlus 13 is the rational buy — our scores land them one point apart with a $600 gap.
