Weak iPhone vibrate? Just restart
Posted 31 October 2007 @ 1pm in Troubleshooting
We’re persistently surprised at how many iPhone troubleshooting issues can be solved by a simple power-off, power-on routine. If you’ve noticed that your unit’s vibrate function is a bit weak, just turn the iPhone off by holding the sleep/wake button for several seconds, then sliding the slider. Power the phone back up by again holding the sleep/wake button, and you should notice a more robust rumble.

What if the vibration totally disappears? This happens to my iPhone several times each day. Restarting it doesn’t help. I don’t know why the vibration disappears, and I don’t know why it comes back.
Anyone?
