Power consumption measurement of Android security protection software

Test methods The popularity of smartphones has enriched our fragmented time, but the trouble with electricity has plagued almost every smartphone user. The Android phone must be a good man, because he has to go home at night to recharge. This story is definitely not groundless, if you have such a Barroth-like intelligent machine, then the charger and data cable will almost carry. With the popularity of mobile internet, mobile phone in the life of a wider range of applications, including privacy data and sensitive information are more and more, people on the privacy of mobile phone security concerns even more than the computer. For this problem many PC platform security software developers have launched a mobile phone-side security software, such as Jinshan, 360 and so on. Of course, all mobile phone security software must be resident backstage, while we enjoy the security software protection, the additional power consumption is unavoidable, below we have several Android platform mainstream mobile phone security software to test the comparison of power consumption. Android software Power-consumption test method The system has a list of battery usage, the user can access the set to view, but because of different vendors, some mobile phones can not get all the application of power line information. However, the following logic can be used to calculate the percentage of power consumption per application: Total software uptime = Software in Linux kernel state run time + software in Linux User state runtime software run time CPU work at each frequency CPU work total time = The amount of time that the CPU works at each frequency during the software run and the proportion of the CPU operating at each frequency during the software operation = The amount of time consumed by the CPU at each frequency level = The ratio of CPU total working time * software Total time * The amount of electricity consumed at different frequencies + The amount of power consumed by data transfer (Wi-Fi or mobile network) + uses the power consumed by all sensors.

Operations include more than 10 SMS send and receive, call/answer telephone more than 10 minutes, WiFi and mobile network for half an hour to read e-books one hour, etc., at night set for flight mode not shutdown. The power consumption data of each security software are recorded and compared separately. Since the second morning of the test the phone restart caused the CPU and memory usage record zero, but the power statistics did not receive an impact, so although the CPU and memory time of only dozens of minutes to an hour, but the actual test time is close to day and night.
