Can you really save electricity? Five Android Power application measurement

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. Yesterday we had four music playback software power consumption comparison, and today for everyone is the five Android platform power-saving software test results. Although there are a lot of energy-saving software on the Android platform and many friends have downloaded and installed them, we will see how the software works. 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 + Amount of electricity consumed (Wi-Fi or mobile network) + use of all sensors consumption five power saving software Jinshan Battery Doctor evaluation version 1.9.3 software size 2.11 MB system Demand Android 2.1 over Dim sum 1.3.6 software Size 1.91 MB System requirements Android more than 2.1 Province PO evaluation version 2.9.6 software size 1.3 MB system Requirements Android 2.1 above the Grand Provincial Power Wizard evaluation version 1.0.42 software size 1.42 MB System Requirements Android 2.1 above 360 battery Guardian evaluation version The 1.0.0 software size 1.44 MB System Requirements Android 2.1 above five power-saving software comparison test method in this comparison we also divide the electricity consumption into several items to test. In the test before the first separate installation of a power-saving software, open the strongest power-saving mode, send and receive a message, call a minute phone, with a mobile phone with a browser open broad bean net (candou.com) home and read the same article after the screen, standby for half an hour. Record the above operation after the total power consumption of mobile phones and power-saving software itself, and then we test again without installing any power-saving software in the case of mobile phone after the operation of the power consumption, and finally compare the above data。
