Thank you for your support of Xiaomi products. When charging the stylus, the tablet’s overall power consumption increases, which can cause the battery to drain slightly faster than usual. This is because the tablet is not only powering its own operations but also supplying energy to the stylus, leading to additional power usage.
Additionally, when the battery level drops below 20%, the system prioritizes essential functions and can adjust performance settings to extend battery life. However, overall endurance can be slightly shorter during this period. To ensure optimal battery performance, it is recommended to charge the tablet first before charging the stylus. Keeping the tablet sufficiently powered can help maintain a stable and efficient charging experience.
