Frequently Asked Questions

❓ Does the Xring O1 chipset in the Xiaomi 15S Pro generate excessive heat during prolonged gaming sessions?
The 3nm fabrication process of the Xring O1 is designed to improve thermal efficiency compared to older nodes. While sustained performance will generate heat, the 3nm process should mitigate throttling better than the 4nm Tensor G3, potentially allowing for longer gaming sessions at peak performance.
❓ How does the Pixel 8 Pro's 'Bypass Charging' feature impact long-term battery health?
The Pixel 8 Pro’s ‘Bypass Charging’ feature directly powers the device when plugged in, reducing heat buildup and minimizing stress on the battery. This can significantly extend the battery’s lifespan by reducing the amount of time it spends at 100% charge, which is known to accelerate degradation.
❓ Is the 90W charging on the Xiaomi 15S Pro compatible with all USB-PD chargers?
The Xiaomi 15S Pro supports PD3.0, meaning it *should* be compatible with many USB-PD chargers. However, to achieve the full 90W charging speed, you'll need a charger specifically rated for that wattage and supporting the correct Power Delivery protocol.
