Five power consumption measurement of Android map navigation 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. We have already done online music playback software (please click "Four of Android music software power consumption comparison test") and energy-saving software (please click "Really can save electricity?") Five of the Android province Electric Application Measurement ") Two power consumption test, but many friends disagree with the test results, so it is necessary to explain again: we have done a series of tests on the use of software only one indicator, and does not include other aspects such as interface, functionality, ease of use, etc. So it's normal for some very good software to score low on our power consumption test. So let's get to the bottom of the list, and today we're going to bring you a comparison of the power consumption of the five Android platform map navigation 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 sensors consumed five map software for this period to participate in the testing of the 1.4.0.1 software size 5.18 MB System Requirements Android 2.0 Map Evaluation version 5.4.98879 software size 5.33 MB System requirements Android more than 1.6 Tiger Map evaluation version 2.35.20111020A software size 1.69 MB system requirements Android more than 2.0 Baidu Map evaluation version 2.1.0 software size 4.68 MB System Requirements Android 2.0 Above Google Maps evaluation version 6.1.0 software size 6.91 MB System Requirements Android 2.1 above five map software comparison test method This test in small series from home to Beijing to complete the journey, completely simulate the use of map navigation software, the process of participating in the test software in addition to Google Maps allPre-download offline map package, and open mobile data and GPS, the screen brightness to the maximum, each software opened after the use of 10 minutes, positioning and location search for common operations, 10 minutes after recording the system's total power consumption and map software power consumption, after recording the power consumption data and the next software test.
