How do I stop my phone from beeping when it completes charging? I have a Samsung Galaxy 2 S running Android 2.3.

When I plug it in to recharge, it beeps when it reaches 100%.

I would prefer that it not notify me with a sound.

However, I can't for the life of me find anywhere that this is set.

Is it possible to disable this annoying chime?
Here's Here's [tnx @GAThrawn] a free app that claims to be able to do that.
