[转]静置功耗测试方法和工具

方法1：Battery Historian 分析工具

链接： http://bugreport.pt.xiaomi.com:9999/ 

在 Battery Historian 中打开后，导入静置测试的Log，在App Selection中找到APP，查看  App Stats 中的信息，如图所示

方法2：Log详细指标收集

可以在  bugreport 中查取 App 耗电信息：举例如下：

1.确定app的uid，比如可以通过找 “Package [com.tencent.mobileqq]” 找到下面的记录：

Package [com.tencent.mobileqq] (ab44b37):
userId=10156

注：一般也可以通过找 “    Apk com.tencent.mobileqq:” 直接找到 App 的详细耗电记录（参见下面2中蓝色的部分）。

2.在 bugreport 的 batterystats dump 中找到 App 的详细耗电记录，比如可以通过找 “u0a156:” 找到下面的记录：
