Is it normal that my turbo charger has noticeable electrical noise when charging?
It has some volume variation depending on the phones battery level or what other device i am charging with it.

Its at my nightstand and it bothers my while i want to sleep. It gets louder if i charge something that's not QC2.0 compatible.
I stopped using it at night because its loud , but i am not sure if its okay or it has some problem.

Anybody else with his charger making noise?
My other charger are completely silent(chromecast adapter, nexus 7 2013 charger, iphone 4 charger, sony bluetooth speaker charger)
Only the turbo charger makes noise and its louder than i am comfortable with.

My Note 2 and Nexus 6 chargers both make a sort of high-pitched whine when plugged in. Come to think of it the charger on my electric razor makes the same sound as well.

yup, mine makes the noise, Google results pointed me to a couple reddit users who experience the same, so there of a few of us out there.

or maybe its a high pitch noise that most people cant hear, but a few with hearing sensitivity that can pick it up. generally, the yoinger you are, the more sensitive you are to noise in the higher pitch range. and gradually the sensitivity goes away as you age.

Finally someone else is having this problem as well. I mean i wish we didn't but it's good to know that I am not the only one. My first original turbo charger was making that noise too so i called Motorola and they sent me another one but that one is making a noise also which makes believe that it's something with a phone.

You either have really good hearing or something is not right with the charger. It will make a high pitched noise but it should not be that loud.

Mine will occasionally "whine" but it doesn't always do it. I have 2 of the Motorola 'turbo' chargers and both of them do it. Its more of a rare occurrence and it doesn't bother me. I bought a different brand one off Amazon that's coming today and can provide up to 30W (I doubt the nexus 6 supports the 12v turbo 2 output but i bought it for future devices). Has anyone else noticed that battery monitors don't reflect the accurate voltage? Mine always shows ~4.1V it could just be my turbo chargers.

Same for me. Thought it was normal due to the extra power output.

One would expect that to be the case. However, I just found mine doing it (it woke me up this morning) and my phone is fully charged. It made no noise while the phone was charging; so either it's only doing it under low load or on the 5v circuit, or my charger degraded overnight, the first night it was in use (I just got the phone yesterday).

Contacting Moto about this for sure.

I can confirm this issue using the EU charger. I didn't notice it until yesterday evening. When my phone was at 100% the charger started making noticeable sounds.

Any feedback from MOTO yet?

As a refrigeration tech I deal with low voltage a lot. Buzzing from a low voltage transformer, which is what you're charger is, Is no good. That usually means the coil inside is overheating. Sounds more like a defective charger to me. I honestly wouldn't even plug that thing in.

This exact thing just started happening to me. I am just hoping that leaving it on the charger isn't a safety hazard (for me or the phone lol)
Also curious to hear Moto's stance on this.

I noticed this 'whine' from the charger too tonight. Actually I found sounds like this fews days ago,but no idea where it came from, -- have thought it was from my notebook. Until tonight I found out the whine gone when I plug out my charger. and yes, that was when my phone got fully charged, will check out if it is there when the phone isn't 100% next time . . .

Mine only whines on a cheapish wireless charger. No whine sound on my turbo charger or my tylt wireless charger. Been doing it since I bought the phone back in November. As far as I can tell it doesn't hurt anything.

That whining you guys hear is just a voltage regulator vibration. It's not really something to be concerned about unless it gets louder. The same thing happens to graphics cards in a computer when they are under heavy load. It doesn't happen to all, but does still happen.

In my case with GFX cards, hot glue around the regulator that is vibrating has normally been a more than satisfactory fix. I doubt you guys will want to tear into your chargers to find the culprit.

Anyway, just giving my experience and knowledge.

Hi. I have this as well with my Moto X Play's charger. It is not so loud but it is enough to ruin my sleep. It only does it when the phone is done charging. One solution is going to the developer options and set it so that the screen does not turn off while charging, but this is probably bad for the battery as my phone is often very warm in the morning when I do this so I cancelled this and just resorted to not charging my phone when sleeping. It does not seem to be a defect, just something that went under QA or desing's radar.
