Does USB debugging affect performance during testing

Question

Android website recommends to test an Android application on a real device before releasing it to others. Based on this I would like to know one thing:

When USB debugging is enabled on the device and android applications are tested in real time, does it have any effect on the functionality or performance of the Android phone?

What I mean to say functionality is, about the working speed, app failure or anything similar.

Answer 1

No, there is none or a little bit that you wont even notice. Your phone will still function normally. You can also use eclipse to log your phones performance and other things. The only thing the eclipse do when you debug the application is attach the debugger to your app and debug it. It will only install your app and lets you test and debug the app. No performance degradation is done. However the application will still occupy the memory on your phone. So it will definitely consume your internal memory like every other application does.
