Why do 5G phones consume power faster than 4G phones?

The biggest difference between 5G mobile phones and 4G mobile phones is the addition of 5G radio frequency and 5G antenna modules. The ultra-high 5G network speed experience of 5G mobile phones is based on more complex and power-hungry antenna and radio frequency designs. These antennas and radio frequencies require battery power to be realized.

The coverage area of ​​5G base stations is small. When the 5G coverage rate is low (the 5G signal is not good in some places), the task of mobile phones to process information will be increased. If the 5G network is preferred, the mobile phone will frequently search for signals, and the search for signals will increase power consumption.

At the same time, 5G mobile phones will also make certain modifications to the antenna itself. Originally, 4G mobile phones had 4 sets of antennas, so 5G mobile phones need to design 8 sets of antennas to ensure signal stability, and each set of antennas needs to be designed with an independent power amplifier. This will increase the power consumption of the mobile phone.

Compared with 4G phones, 5G phones have greatly improved performance. 5G phones need to handle more tasks. With faster network speeds, the data processing capabilities and data processing volume of mobile phones will be improved accordingly. When 4G and 5G phones keep transmitting data, the power consumption of 5G will definitely decrease the fastest.

5G mobile phones have faster transmission speeds, larger bandwidths, and more data can be read and written per unit time. The power of the chip itself is increased, the data transmission volume is increased, the hardware is increased, the heat is increased, and the frequency band management needs to be continuously optimized. Naturally, the power consumption will increase from the data point of view. At present, the power consumption of 5G mobile phones is about 20% higher than that of 4G mobile phones. "

In response to the significant increase in power consumption of 5G mobile phones, mobile phone manufacturers have first increased the battery capacity of mobile phones. Currently, the battery capacity of most mobile phones exceeds 4000 mAh; second, they have increased the power of fast charging; third, when the network usage is large, the system will automatically adjust to 5G mode, and in standby mode, it will fall back to 4G mode, so as to balance data usage, speed and power consumption in real time and extend battery life. Although the power consumption of 5G mobile phones is indeed higher than that of 4G mobile phones, there will be no significant difference in battery life when using them.
