Just out of curiosity. Logically thinking, does Android debugging mode slows down the performance of Android devices?
How can I prove to users that Android debugging does or does not slow down the Android?
P.S.: I need specific answer and reliable source to how can I prove it?
Yes. Attaching a debugger almost always slows down the performance. The best way to prove any performance related argument is always to run some tests. Set some timers in your code and gather the data empirically. Then you’ll know not only which way is faster but by exactly how much.
For a ‘specific answer’ – measure and your tests will be the ‘reliable source’
