PowerSoundDisabler disables the sound and vibration played when you connect an iDevice to a power source or respring

  To warn a user when an iDevice is connected to a power source, Apple designed a sound and set a vibration that are played when our iDevice starts to charge or when we do a respring. You all know the sound, the vibration is just as well known, but maybe not all of you are really that interested in experiencing it every time you connect your terminal to the computer or an adapter or do a respring, and this is where PowerSoundDisabler comes in. This new tweak from Cydia makes that sound and disables that vibration as soon as it is installed and to reactivate them you just have to uninstall the tweak.

A simple MS tweak disabling sound and vibration after respringing or connecting via USB.

  PowerSoundDisabler is available for free in Cydia's BigBoss repo.
