[Android電量] 耗電資訊統計服務battery / BatteryStats

• 通過執⾏battery指令(不需要root)
• adb指令擷取電量量消耗資訊
• 擷取整個裝置的電量量消耗資訊
• 擷取某個apk的電量量消耗資訊
• batterystats使用步驟

通過 adb shell dumpsys battery，傳回結果後有電池的各種資訊，其中就包括

level(百分⽐比)

adb指令檢視電池電量量資訊:

adb shell dumpsys battery

也可以将上述指令标準輸出到⼀一個⽂檔案，來進⾏行行分析。 windows : > xxx.txt Mac/Linux: > xxx.txt

将獲得的資料轉換為可視化的html⽂檔案 指令:python historian.py xxx.txt > xxx.html

關于電量，還可以通過battery-historian⼯工具來擷取。

第一步：清除手機電量消耗曆史情況（連接配接手機）

adb shell dumpsys batterystats -enable full-wake-history =====打開全量日志記錄
adb shell dumpsys batterystats --reset =====清空電量資料           

第二步：設計場景測試（注:不連結手機）

\

第三步：導出測試資料

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

exit-----退出shell指令
