Frequently Asked Questions for Xiaomi 15 Ultra

Why is General sensitivity set to 140 for Xiaomi 15 Ultra?

Xiaomi 15 Ultra features a 480Hz touch digitizer and 6.73-inch screen. In OB55, standard aim assist tends to drag crosshairs onto the opponent's chest. Setting General to 140 provides the optimal swipe acceleration to break chest stick without flying over the target's head.

Where should I place the Fire Button on Xiaomi 15 Ultra?

Place the Fire Button at Bottom-Right (18% thumb lift clearance). Keep the button size at 42% to ensure your thumb has enough screen runway for clean vertical drag flicks.

Is DPI modification necessary on Xiaomi 15 Ultra?

Default stock DPI is usually sufficient, but competitive scrim players recommend setting DPI to 500 in Developer Options for slightly sharper pixel tracking. Do not exceed 500 DPI to avoid ghost touch issues.
