4G Lab: Why does LTE mobile phone consume a lot of power?

With China Telecom and China Unicom obtaining FDD-LTE trial commercial license, the 4G popularization war in our country officially kicked off. 4G speed network brings users high-quality mobile internet life experience, 4G terminal is getting higher and higher in our life, but the power consumption of 4G mobile phone seems to have become a criticism in the industry. Many netizens complain about the 3G era smartphone battery. A charge has become history, and it has become a normal state in the 4G era. So why is the 4G mobile phone running so fast? The editor summed up the reasons for sharing with the netizens.

4G Lab: Why does LTE mobile phone consume a lot of power?

Incomplete network

At present, the universal 4G standard includes two standards. The technology includes TD-LTE and FDD-LTE. At the end of last year, the Ministry of Industry and Information Technology officially issued the TDD-LTE mode 4G network commercial license to the three major operators. Construction is a gradual process. At present, there are no 4G networks in many places, and our 4G mobile phones generally use the 4G network by default. In the case of poor network conditions, the mobile phone will automatically search for high-quality networks. Frequency disconnection and networking will increase the running load of the mobile phone, and the direct result is that the battery consumes too much power.

High power consumption due to high performance

With the advancement of smartphones, users have become more and more demanding on the performance of mobile phones. From the original single-core processor to the current real eight-core processor, from the original 16MHz Dragon Ball EZ The processor, up to now 2.5GHz Qualcomm Snapdragon 805, from 720P high-definition screen to the current 2K ultra-clear screen, performance improvement, will certainly bring mobile phone power consumption, in the face of user performance experience and high power consumption The user eventually made a compromise and sacrificed power for a good performance experience.

Multi-task acceleration power consumption

The improvement of hardware performance and the increasingly intelligent operation of the mobile operating system enable users to start more and more complex tasks at the same time. When these multi-tasks have less impact on the running speed, we often ignore them during use. Turning off some background programs in real time will cause multiple programs to run at the same time. When we turn off the screen, it seems that the mobile phone has entered a sleep state. In fact, the mobile phone can't get a rest at all. These programs running in the background unknowingly consume this mobile phone. The battery power, when we next open the screen of the phone, will be surprised to find that the phone has been red.

How to save battery power

Reduce the screen brightness: the screen resolution is getting higher and higher, the screen size is getting bigger and bigger, which improves the user's visual experience, but at the same time increases the load of the mobile phone. When using the mobile phone, we can adjust the brightness of the mobile phone screen appropriately. Reduce battery load and save power.

Timely shutdown of 4G network/background program: At present, 4G network is not perfect. When using 4G mobile phone, we can choose whether to enable 4G mode according to local network conditions, and close 4G data transmission when 4G data traffic is not needed. Ensure that the mobile phone runs in a better network environment; at the same time, develop a good machine habit, clean up the background running program in time when not using some programs, reduce the background running pressure and reduce the power consumption of the mobile phone.
