Detailed Comparison

Performance

OnePlus 13

The Snapdragon 8 Elite is the fastest mobile chip available, and OnePlus has tuned it well.

This is the fastest Android phone you can buy right now — everything from app launches to gaming feels instantaneous.
Thermal management is impressive — sustained performance during long gaming sessions stays consistent.

Xiaomi 15

The Snapdragon 8 Elite with 12GB RAM delivers flagship-tier performance that's smooth and snappy for everyday use, gaming, and multitasking. However, the compact body struggles to dissipate heat under sustained loads, causing notable thermal throttling during extended gaming sessions.

Snapdragon 8 Elite scores ~2,990 single-core and ~9,114 multi-core on Geekbench 6 — genuinely fast
Thermal throttling is a real issue — fails to complete 3DMark GPU stress tests and gets uncomfortably hot
CPU throttles to 72-77% of peak under sustained load — compact chassis limits cooling capacity

Camera

OnePlus 13

A major step up for OnePlus cameras, though still not quite matching Apple and Samsung's best.

The Hasselblad color science produces natural, film-like images that many will prefer over Samsung's punchy processing.
Low-light performance has improved dramatically but still falls slightly behind the iPhone 16 Pro in challenging conditions.

Xiaomi 15

The triple 50MP Leica system shines with its main sensor and improved 2.6x telephoto, earning a DxOMark score of 146. Leica color profiles produce natural, pleasing images with excellent dynamic range. The ultrawide camera is the clear weakness, with noticeably more noise in low light and no autofocus.

50MP main Leica Summilux camera delivers excellent photo quality with natural colors and strong dynamic range
2.6x optical telephoto is a meaningful upgrade over the Xiaomi 14 — sharp and versatile
Ultrawide camera is the weakest link — subpar quality, no autofocus, noticeably more noise in low light
DxOMark camera score of 146 — good but not class-leading among 2025 flagships
