batterystats使用条件

• 5.0以上系统
• battery-historian脚本

batterystats的启动

启动统计Battery数据的话，首先要初始化batterystats数据

<code class="hljs livecodeserver has-numbering">adb <span class="hljs-built_in">kill</span>-server> adb devices> adb <span class="hljs-built_in">shell</span> dumpsys batterystats <span class="hljs-comment">--reset</span></code><ul style="display: block;" class="pre-numbering"><li>1</li><li>2</li><li>3</li><li>4</li><li>5</li></ul>

上面的操作执行完毕后，拔掉手机，操作你的App，操作完成后，重新连接手机，执行下面的命令，收集Battery数据:
adb shell dumpsys batterystats > batterystats.txt
得到这些数据后，这个时候使用我们的battery-historian来生成我们可见HTML报告:
python historian.py batterystats.txt > batterystats.html

得到的报告如下:

Battery Historian指标

在Android性能专项测试之battery-historian试用一文中已经介绍了一些属性，但是目前又增加很多，下面来看看新加属性的意义:

属性意义gpsgps是否开启sync是否跟后台同步mobile_radio是否开启radiowake_reason唤醒原因phone_in_call进行通话

batterystats信息过滤

Battery History

电量相关数据的时间序列:

Per-app mobile ms per packet

radio唤醒时间除以数据包发送次数，该时间越小代表性能越好，一个高效的App会将所有的流量转化为batches。

All partial wake locks

所有程序中wakelock，关注持续时间和数量
