推荐答案

如果您想测试省电模式 (PSM):

以下适用于 Android Studio 3.4.1 和 Google Pixel 2 XL 手机:

The following works with Android Studio 3.4.1 and a Google Pixel 2 XL phone:

$ adb shell dumpsys battery unplug # a charging device cannot enter PSM
$ adb shell settings put global low_power 1 # enter Power Saving Mode (PSM)

这仅适用于具有标准省电模式的设备，例如三星的，但不适用于华为的设备.在某些三星设备上，此设置存储在键控 psm_switch 的全局设置中，如上所述.

This only works on devices that has the standard Power Saving Mode, like Samsung's, but not Huawei's, for example. On some Samsung devices, this setting is stored in global setting keyed psm_switch, as mentioned above.

您可以通过将 low_power 设置为 0 或再次启用充电来退出 PSM:

You can leave PSM by setting low_power to 0 or by enabling charging again with:

$ adb shell dumpsys battery reset
