The 6.32-inch 165 Hz 1.5K AMOLED panel is the only true 165 Hz compact-flagship display on the market and pairs that refresh rate with a measured 1,800 nits brightness, 460 ppi pixel density, Crystal Shield Glass, and HDR10+/Dolby Vision support. Native 165 Hz support in popular FPS games is a real differentiator. Notebookcheck flags 120.7 Hz PWM dimming that can cause eyestrain for sensitive users.

The 6.73" LTPO AMOLED at QHD+ 120Hz with Dolby Vision and HDR10+ is among the best smartphone panels of 2023 — 2,600-nit peak brightness, though only briefly under direct sunlight as Wired notes.
OnePlus 15T
Snapdragon 8 Elite Gen 5 paired with 12-16GB LPDDR5X Ultra Pro RAM delivers flagship synthetic scores — Notebookcheck recorded Geekbench multi-core 10,976 and 3DMark Wild Life Unlimited 29,901, on par with the larger Xiaomi 17 and Honor Magic8 Pro Air. The problem is sustained: in the 3DMark Wild Life stress test the GPU drops over 50% and the back of the phone hits 50 °C, which both Notebookcheck and SuperSaf flag as a deal-breaker for long gaming sessions.

Snapdragon 8 Gen 2 + 16GB RAM delivers flagship-class performance with strong thermal headroom — Xiaomi's tune is among the best of 2023 SD 8 Gen 2 phones for sustained tasks.
OnePlus 15T
This is the section the OnePlus 15T was built to win. The 7,500 mAh silicon-carbon 'Glacier' cell is the largest ever fitted to a true compact phone — 50% bigger than the iPhone 17's pack in a similar footprint. Notebookcheck measured roughly 1.5 days of real-world endurance at 150 cd/m². Wired charging tops out at 100 W, wireless at 50 W. The only friction points are the missing built-in magnets for MagSafe-style alignment and the still-USB-2.0 port.
Xiaomi 13 Ultra
5,000mAh battery + class-leading 90W wired and 50W wireless charging — Reddit's drain shootout placed it ahead of S22 Ultra, OnePlus 11, and Pixel 7 Pro at 10h 26min total SOT.
