We expected that all Android phones with kitkat have adb binary by default.
But we were wrong about that. Some phones like MotoX does not have it.
Porting adb into bin folder will require root which is not solution.
Another way is the PC version that can retrieve statistics from pc side adb.
It might be uncomfortable to plug to pc everytime for checking wakelocks, but after google has restricted access for wakelock statistics this could be the only option for non root phones.
Is there a link to the PC version? I'm ok with doing that.
