Wireless Charge Pad Making Ringing Sound?

[ishredthecello]

Has anyone else noticed a really really faint ringing type sound coming from the wireless charge pad? It was driving me crazy this morning of hearing it, not hearing it. Finally traced it to the witless charge pad.

Anyone else with this?

Yes! Omg it has been driving me crazy since I got my wireless charger. I had no idea what was making double ringing noise every 4 seconds for past 3 days. Then I found out it is the wall charger, not the plate. When u put it close to ur ear while plugged in u will hear repeating sound interval that comes from inside. Once u put ur phone on the plate it changes to very quiet buzzing. But if not charging, it will make two ring sounds every 4 seconds. Its annoying as ****. We should try to return it and get a new one. But I fear they r already out of stock or this is how the machine works so the annoying noise it makes is just the part of the charger itself.

I guess we are the only two. Since that time I haven't noticed it, but its so faint I may have just not heard it since I wasn't listening for it.

Probably inductor whine.

I see the exact same on my wireless charger. Did you get a new replacement charger? I would like to know if the new charger did not have the noise issue.

Yep I think you are right. It's probably a frequency thing. The coil is sensitive to a particular frequency so vibrates causing the noise..

I have 3 of them and all make this noise from the wall charger when idle. One of them have a higher frequency noise making it really annoying for use in the bedroom. I doubt they are faulty so I have not bothered returning them, but if someone have, please share your story.
