[Android电量] 耗电信息统计服务battery / BatteryStats

• 通过执⾏battery命令(不需要root)
• adb命令获取电量量消耗信息
• 获取整个设备的电量量消耗信息
• 获取某个apk的电量量消耗信息
• batterystats使用步骤

通过执⾏battery命令(不需要root)

通过 adb shell dumpsys battery，返回结果后有电池的各种信息，其中就包括

level(百分⽐比)
adb命令查看电池电量量信息:

adb shell dumpsys battery

adb命令获取电量量消耗信息

获取整个设备的电量量消耗信息

adb shell dumpsys batterystats | more

获取某个apk的电量量消耗信息

adb shell dumpsys batterystats com.sdu.didi.psnger | more

由于输出信息太多，可使⽤用命令more 或者 less 分篇查看 输出信息如下(由于篇幅， 只粘贴部分)

也可以将上述命令标准输出到⼀一个⽂文件，来进⾏行行分析。 windows : > xxx.txt Mac/Linux: > xxx.txt

将获得的数据转换为可视化的html⽂文件 命令:python historian.py xxx.txt > xxx.html

关于电量，还可以通过battery-historian⼯工具来获取。https://github.com/google/battery-historian

batterystats使用步骤

第一步：清除手机电量消耗历史情况（连接手机）

adb shell dumpsys batterystats -enable full-wake-history =====打开全量日志记录
adb shell dumpsys batterystats --reset =====清空电量数据

第二步：设计场景测试（注:不链接手机）
\

第三步：导出测试数据

adb shell dumpsys batterystats > d:/batterystat.txt   =======生成TXT文件（导出到本地）
adb shell dumpsys batterystats > /sdcard/batterystat.txt   =======生成TXT文件（导出到SD卡）

exit-----退出shell命令
