Four Android music playback software power consumption comparison test

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. In the case of battery power consumption, we find that the speed of power consumption is also connected with the power consumption of each app you install. In order to help the majority of users to better choose App Application, the Candou evaluation team tried a horizontal test of the more well-known app applications in China, hoping to get their power consumption in a relatively objective way for your reference when choosing to download, and today brings you the Power test for four music playback software. 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 + Power consumption (Wi-Fi or mobile network) + use of all sensor consumption four music playback software cool music test version 1.9.3.1 software size 2.93 MB system requirements Android more than 1.6 meter music evaluation version 3.3.0.00 software size 2.61 MB system requirements Android more than 1.6 QQ music evaluation version 2.2.0.1290 software size 2.4 MB system requirements Android 1.6 above every day sounding evaluation version 2.9.2 software size 4.09 MB system requirements and Roid more than 2.0 local and online playback mode power consumption test since most music playback software has already supported online music playback, we tested the respective power consumption in both local and online playback modes. Because of the MIUI system's own consumption statistics, it simplifies the calculation process of electricity. After we start playing, we turn on the system's own power consumption record and close the screen to avoid the test results due to screen power consumption. The test time is 10 minutes, after each test completed, empty the phone's battery statistics.
