HTC EVO charger emits high pitch noise when phone is fully chargered???

[wakeboardr360]

When i put my fully charged HTC EVO on the HTC charger it came with, the charger emits a high pitch obnoxious sound similar to those ringtones that can't be heard by some people.

I've put my phone on a blackberry USB charger and there was no ringing.....anyone else have this problem or is this just me???

Get a new charger

This happened to my Pre also. Unplug it when it's charged.

you might be a dog, or have dog hearing.

Happens on my laptop actually. I actually use a blackberry charger the majority of the time and haven't noticed anything, If I remember I will check tomorrow morning.

I have heard the same thing on a Motorola charger i use at the office. Consequently, i have heard that same high pitched whine noise on another device, but same charger.
