The decision ultimately depends on which flagship priorities matter most to you.
Design and Display
Both smartphones feature premium materials with glass fronts and backs paired with aluminum frames.
Xiaomi uses Gorilla Glass 7i and an IP68 rating, while OnePlus offers IP68/IP69 certification for greater water and dust resistance.
The OnePlus 15 also includes an ultrasonic fingerprint scanner, which feels more premium and responsive than Xiaomi's optical solution.
Users who prioritize durability may find the OnePlus more reassuring in everyday use.
Xiaomi offers a 6.83-inch AMOLED panel with 144Hz refresh rate, Dolby Vision, and 3,500-nit peak brightness.
Colors are vibrant, contrast is excellent, and outdoor visibility is outstanding.
The OnePlus 15 counters with a 6.78-inch LTPO AMOLED display featuring a 165Hz refresh rate, adaptive refresh technology, and HDR Vivid support.
The panel feels slightly more fluid during gaming and scrolling.
Overall, the OnePlus 15 takes a narrow win for display and build quality due to its LTPO technology, faster refresh rate, and stronger durability.

Performance and Battery
The Xiaomi 17T Pro is powered by the MediaTek Dimensity 9500, a flagship-grade 3nm chipset paired with UFS 4.1 storage and up to 16GB RAM.
Multitasking and gaming are effortless.
However, the OnePlus 15 uses Qualcomm's Snapdragon 8 Elite Gen 5 with Adreno 840 GPU, expected to deliver stronger gaming performance and better sustained efficiency.
For heavy users, the OnePlus offers a slight performance advantage.
Battery life is a major strength for both. Xiaomi packs a 7,000mAh battery with 100W wired and 50W wireless charging.
The OnePlus 15 goes even bigger with a 7,300mAh battery, 120W wired charging, 50W wireless charging, bypass charging, and reverse wireless charging support.
