Many people use Xiaomi mobile phones, and we know something about the MIUI system of Xiaomi mobile phones. Like other mobile phone systems, MIUI will also be updated and optimized regularly. Recently, many users have reported that MIUI mobile phones consume too much power. What is the reason? Xiaomi officially summarizes several reasons for the excessive power consumption of MIUI mobile phones. Let's take a look.
On November 9, Qiao Zhongliang, a senior manager of Xiaomi, posted a post in Xiaomi Community, analyzing the reasons why MIUI users said their mobile phones consumed power quickly. It can be seen that the location service is not closed, applications (games, videos, music, etc.) are opened for a long time, and the screen is not set to automatically close the screen. The screen brightness is the main reason for the fast power consumption of the phone.
Qiao Zhongliang said: Sometimes the positioning switch and Bluetooth switch are opened by everyone on their own initiative, and some applications are started by the application guide. The system cannot be shut down by default, and it will remain unchanged without attention, leaving a hidden danger of power consumption.
Qiao Zhongliang also explained the principle of power consumption of mobile phones. The vibration of the speaker needs to consume mechanical energy. When the screen is kept open, it will consume light energy. When the processor calculates, it will consume heat energy, and the electricity is consumed when it is converted into other energy. The higher the hardware specification, the faster the power consumption in the same scenario. For example, the sound effect of four speakers is better, the screen display effect of high refresh rate is better, and the 5G network download speed is faster, but the power consumption per unit time will also increase. If you want a better use experience, you need to consume more power.
The schematic diagram of hardware power consumption simply explains this principle. Assuming that the hourly power consumption of speakers, CPUGPUs, screens, and 5G communications is 100mA, 150mA, 260mA, and 50mA respectively, 1010mAh of power will be consumed per hour of gaming (using 4-core processors), and 560mAh of power will be consumed per hour of navigation.
