With the popularity of 5G, many mobile phone users have already experienced the convenience of 5G. Whether at home or abroad, it can be seen from the investment of major operators and mobile phone manufacturers to 5G that the popularization of 5G is just a matter of time.
But just as everyone was waiting for the full coverage of 5G, some operators reminded us to “turn off 5G.”
On February 28th local time, the mobile communication business company “Verizon Wireless” under Verizon, the largest mobile communication network operator in the United States, released a Twitter. The Twitter content suggested that users turn off the 5G network switch of their smartphones to save mobile phones. Power.
The tweet stated that if the user finds that the phone’s power is consumed faster than normal, they can turn on the phone’s LTE (Long Term Evolution) to reduce power consumption. Of course, turning on LTE means turning off the 5G network function of the mobile phone. Verizon’s statement like this is better than telling users to “turn off 5G.”
LTE is a 5G network backup function. Turning on LTE is equivalent to switching from 5G network back to 4G network. What is puzzling is that Verizon, as the largest operator in the United States, has previously purchased 5G spectrum at a high price of 45.5 billion US dollars to vigorously promote the development of 5G users. Now it is recommended that everyone turn off the 5G network switch for battery life. People can’t figure it out.
However, as a user, the question that may be more concerned is: Does turning on the 5G switch really consume battery power?
5G mobile phone power consumption problem does exist
If you pay attention to mobile phone information, you will find that the battery capacity of mobile phones in the past year or two has increased, such asToday, around 4500mAh is the mainstream battery capacity. Many 5G mobile phone batteries have reached 5000mAh capacity, but their battery life is almost the same as that of past 4G mobile phones.
Why does this happen? Lu Weibing, President of Xiaomi China, once posted a Weibo to popularize this issue:
A simple conversion, If a 4000mAh battery is to be used on a 5G mobile phone to guarantee the same endurance as the original, it must be upgraded to at least 4800mAh to reach the endurance of a 4000mAh battery in a 4G mobile phone.
But it should be noted here that Lu Weibing said that when the 5G network is fully turned on, the 4000mAh 5G mobile phone battery is approximately equivalent to the 3200mAh of the 4G mobile phone.
Although it is difficult to achieve “full 5G network opening” based on the current 5G network coverage, if the 5G network switch is turned on for a long time, 5G mobile phones will automatically connect to the 5G network in areas covered by 5G networks. Power consumption during these periods will increase.
Lei Jun also expressed his opinion on this, saying that the 5G flagship machine must be purchased with 4500mAh and above for the battery life to be practical.
Lu Weibing directly pointed out: “Choose a 5G mobile phone with a small battery, you will cry later“.
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 more power-consuming antennas. Based on the design of radio frequency, these antennas and radio frequencies need to be driven by battery power. If you want to fully meet your expectations, then 5G mobile phones will inevitably consume more power.
