Keyboard Vibration Settings auf Xiaomi
Keyboard vibration on Xiaomi phones is controlled by the on-screen keyboard app itself, not by the general system haptics found under sound settings. That is why turning vibration on or off under Settings ➔ Sound & vibration has no effect on the buzz you feel while typing.
The actual toggle lives inside the keyboard preferences. Open Settings ➔ Additional settings ➔ Languages & input ➔ Manage keyboards ➔ Settings ➔ Preferences, then enable or disable Haptic feedback on keypress. Once enabled, you can usually adjust the intensity in the same menu, so a buzz that feels too strong does not have to mean turning the feature off completely.
This toggle only affects typing feedback. It does not change vibration for notifications, calls, or Focus mode, since those run through separate system channels. If your phone keeps buzzing on every keypress after disabling this option, check whether a third-party keyboard app is installed, since it will use its own independent vibration setting.
Disabling haptic feedback can slightly extend battery life on some devices, since the vibration motor fires less often, though the effect is minor in daily use.
