1. The power consumption is related to the usage scenario, wireless network environment, and battery life. If the network environment is poor and the device needs to search for the network continuously, the power consumption will increase. You are advised to set the Wi-Fi frequency to 2.4 GHz to reduce the system power consumption.

2. The battery capacity is displayed in a non-linear manner in the range of 100%–90%. As a result, you may feel that the battery drops quickly. Please pay attention to the battery lifespan. To prolong the battery life, remove the charger immediately after the battery is fully charged to avoid charging for a long time.
