[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 eroqltechn:/ $ dumpsys battery Current Battery Service state: mBootCompleted: true AC powered: false #有线充电器状态 USB powered: true #USB连接状态 Wireless powered: false #无线充电状态 Max charging current: 0 #最大充电电流，单位微安(uA) Max charging voltage: 0 #最大充电电压，单位微伏(uV) Charge counter: 0 status: 2 #充电状态，UNKNOWN=1，CHARGING=2，DISCHARGING=3， NOT_CHARGING=4，FULL=5 health: 2 #电池健康状态:只有数字2表示goodpresent: true #电池是否安装在机身 level: 93 #电量: 百分比 scale: 100 #满电100% voltage: 4265 #电池电压 temperature: 289 #电池温度，单位是0.1摄氏度technology: Li-ion #电池种类batterySWSelfDischarging: falsebatteryMiscEvent: 0 mSecPlugTypeSummary: 2 LED Charging: true LED Low Battery: true current now: 217 #电流值，负数表示正在充电charge counter: 0 Adaptive Fast Charging Settings: true USE_FAKE_BATTERY: false SEC_FEATURE_BATTERY_SIMULATION: false FEATURE_WIRELESS_FAST_CHARGER_CONTROL: true mWasUsedWirelessFastChargerPreviously: false mWirelessFastChargingSettingsEnable: true BatteryInfoBackUp mSavedBatteryAsoc: 88 mSavedBatteryMaxTemp: 429 mSavedBatteryMaxCurrent: 1746 mSavedBatteryUsage: 6447 FEATURE_SAVE_BATTERY_CYCLE: true 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) heroqltechn:/ $ dumpsys batterystats com.sdu.didi.psnger Discharge step durations: #0: +1h43m34s304ms to 92 (screen-off, power-save-off, device- idle-on) #1: +1h54m26s635ms to 93 (screen-off, power-save-off, device- idle-on) #2: +1h59m33s225ms to 94 (screen-off, power-save-off, device- idle-on) #3: +1h58m56s325ms to 95 (screen-off, power-save-off, device- idle-on) #4: +2h2m44s341ms to 96 (screen-off, power-save-off, device-idle- on) #5: +2h2m20s111ms to 97 (screen-off, power-save-off, device-idle- on) #6: +1h46m1s361ms to 98 (screen-off, power-save-off, device-idle- on) Estimated screen off time: 8d 0h 17m 12s 800ms Estimated screen off device idle time: 8d 0h 17m 12s 800ms Daily stats: Current start time: 2019-01-22-04-46-42 Next min deadline: 2019-01-23-01-00-00 Next max deadline: 2019-01-23-03-00-00 Current daily steps: Discharge total time: 7d 19h 32m 18s 800ms (from 3 steps) Discharge screen off time: 7d 19h 32m 18s 800ms (from 3 steps) Discharge screen off device idle time: 7d 19h 32m 18s 800ms (from 3 steps) Daily from 2019-01-21-11-43-46 to 2019-01-22-04-46-42: Discharge total time: 8d 3h 3m 13s 700ms (from 3 steps) Discharge screen off time: 8d 3h 3m 13s 700ms (from 3 steps) Discharge screen off device idle time: 8d 3h 3m 13s 700ms (from 3 steps) Charge total time: 6h 35m 21s 800ms (from 18 steps) 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
