Cell Phone Suicide

So I forgot to charge my cell phone. Its the moto razr all the cool kids had (like 3 years ago). The battery is going dead but the phone decides it needs to beep and/or vibrate to make sure I'm aware of the fact that the battery is going dead. What I dont get is, why? Its like stabbing yourself when bleeding out from a gunshot wound. What crazy asian that invented these things thought it would be a good idea to use every last drop of battery life your phone has left to make sure you know that no matter what the next time you try to make a phone call, the damn thing will turn off.

So moral of the story, there any way to shut that "feature" off? I can silence the beeps, but then it vibrates and visa versa.
