Turn off buzz when plugging in iPhone

I keep my iPhone on silent pretty much all the time. When I plug it in to a charger, it goes "buzz-buzz". My iPad doesn't do this. Both behaviors are the same with iOS 6 and 7.

How do I make my phone not do that?

I have checked the activity-specific sound settings (like Lock Sounds [off], etc). The main suspicious ones are Vibrate on ring and vibrate on silent. I would still like to have it buzz (vibrate) upon receiving texts, calls, and calendar alerts.

Solution 1:

There is no way to natively disable this other than turning off vibrations completely. Only your iPhone does this because the iPad (and the iPod touch) don't have vibrate motors.

If you jailbreak, there is a tweak called PowerSoundDisabler. It's a simple tweak to disable sound and vibration when respringing or plugging in via USB.

Solution 2:

1. Update to iOS 9.
2. Go to Settings, Sounds, Vibrate on Silent and deactivate it.

Solution 3:

Plug in your head phones into the phone, turn off silent mode and turn your headphones volume down.

You may also want to turn off vibrations in sounds then charge your phone! It will make no vibrations and if you put it back on mute, your phone won't vibrate as well :)
