android adb is really slow after a day(Devices are connecting to host all the time)

Question

All my adb commands to some of my connected devices are really slow. The result shows after 1-2 mins. Fow example adb shell will wait 1 min to enter. And it will stuck after enter the adb shell.

This always happened after 1-2 days after reboot these devices and only reboot those devices could solve the problem.(My devices are connecting all the time to host machine)

Restart adb or close/open devices' debug mode or reconnect these devices cannot solve the problem only I could reboot them.

Is there some problems with my android ROM or the bug of the ADB?

Thanks

This only happened on Android 6.0.

Answer 1

First, you can restart adb by,

1. adb kill-server
2. adb start-server

Second, you should unplug the cable and plug it in again.

And then , test adb response again
