Why does the Xiaomi Pad 7 Pro drain battery quickly when watching videos, especially HDR videos?

The screen resolution and brightness of this product have been significantly improved compared to the previous generation. While this enhances the video viewing experience, it also increases power consumption, especially when HDR video features are enabled. Faster battery drain in such scenarios is normal. If you feel that the battery drains too quickly and it affects your experience, you can try enabling auto brightness for better battery efficiency.
