Dash Charger noise? - OnePlus 3 Questions & Answers

Does the Dash Charger make noice also, is it Normal? Thx!

Just checked but No Sound at all.

Mine does - a very slight buzzing whirling noise...have to have ear less than a foot away to hear it. Not sure if it's normal, but my Op2 adapter made pretty much the same noise.

Normally i would see cheap condensators placed.

Mine is silent charging... But when its not plugged in to the phone theres a hiss... Like a snake in the room!.

Yes i have some situation. Power supply does a noise. Bit it'is very rarely

In my personal experience I have noticed an extremely high pitched noise from pretty much every mobile phone charging brick I have ever used. Nothing to worry about.

Mine has always been 100% silent, but if you're getting some kind of noise out of it, try plugging it into the power strip, or plug it in at a different location and see if it stops. It might be that the power coming into your house is "dirty". I used to build pro audio studios, and we always had to use power conditioners due to the power coming into the location giving producing substantial noise in the lines, both analog and digital.. A lot of it has to do with slightly out of phase AC current, and when it's switching to DC in the charger transformer it can make noise at the front end of said transformer. Also, the dash charger pulls a significant amount of current to be transferred so I can imagine some noise would be expected with unconditioned power going into it.
If it's annoyingly audible I would plug it in elsewhere and if it still makes the same noise contact OnePlus and get another one.

So Many people facing same sound issue inside the charger,its normal

Mine is silent and if the sound being emitted by your charger is like a buzzing one is extremely low then it can be considered as normal but if its even audible during normal room sounds then you should get it checked.

If you unplug your charging cable from the phone before unpluging your charging brick from the wall outlet, then some "charge" may remain in the charging brick. Just remove the charging brick from the wall outlet first, wait about 3 seconds for the remaining "charge" to transfer from the charging brick to the phone, and then unplug your cable from the phone. By doing these, there is no remaining "charge" in your charging brick and it won't make that buzzing noise. That buzzing noise occurs on all of my other charging bricks as well (for samsung tablet, lenovo smartphone, oneplus 2). Of course, if the charging brick makes that noise, just plug your cable in the phone (without plugging your charging brick in the wall outlet) - this will transfer the remaining charge from it to the phone and the charging brick will stop making that noise.

HD Dock makes high pitch noise

Has anyone noticed the high pitched noise emitted from the dock? As soon as I turn off the screen the pitch changes slightly. As soon as I touch the screen it stops, and no im not moving the xoom at all to adjust the slightest touch on the screen stops the high pitched noise.
it doesnt seem to stop when playing music either.
the only thing that stops it is interacting with the touchscreen (touching the screen while off doesnt change noise at all)
another neat find.... if i unplug the dock it still makes the noise
Yes mine was doing this too!!! unpluged it and havent tried it sense
i just took mine in to get replaced hoping the dock has the issue.
are you running 3.0 or 3.0.1? are you rooted? are you running the 1.5Ghz overlocked kernel? is it overclocked or just using the standard 1.0Ghz clock speed
i am *thinking* the kernel may be causing this but am reluctant to flash the stock back just yet.
just got my replacement and the noise is gone i would take yours back there might be a faulty batch floating around.
... seems to have started again, but isn't happening all the time. i'll run through some test cases to narrow it down.
Sounds like a ground issue if you are able to touch it to stop it.
Exactly, think about it for a second. You touch the screen, completing the electric circuit. You have grounding issues and I bet the speakers use a non grounded plug which sucks.

Yup grounding issue looks to be the problem.Wonder if its the way the docks charge the xooms? And the transformers in the power packs for the phones whine as well which drives me nuts at night.
I do not have this issue, but have what is probably a related issue. I have a pair of external speakers plugged into the dock. When I remove the Xoom there is a loud hum throughthe external speakers.
The speakers and dock are plugged into the same power strip. I may return this one and see if a new one is any different.

Car dock

Well, I got the Samsung dock, and as much as I like the E4GT, the dock is terrible. Here's my experience:
1. There's a ton of line noise when the phone is docked but nothing is playing, just like with the Epic. I'm using the OEM charger, but that's not the problem--using the same charger, the Photon's car dock is absolutely silent. Samsung must be using some cheap electronics in this thing, and it's simply horrible. (Sorry for venting, but seriously...)
2. The software isn't nearly as seamless as the Photon's either. First, on the Photon, when you dock an app starts that essentially takes over the home button. That means you can move back and forth between the app and the home screens easily. On the Samsung, it seems like once you leave the Vlingo app to, say start a radio streaming app, you can't get back to the dock mode. At least, not without unplugging/replugging the dock connector, but that's extra wear and tear. If I'm wrong about this, please let me know.
Then, the Photon app allows for 4 custom apps to be assigned. That provides a great deal of flexibility, and again it's easy to go from one app to another and then back to dock mode.
Overall, the Samsung car dock experience is nowhere near the Photon's. Motorola really did a great job with this, and Samsung makes it look like they gave actually using the phone in the car zero thought.
What's everyone else doing to make this experience more usable? I'm still choosing between the Photon and the E4GT, and the car dock definitely is a mark in the Photon's favor.
1) Use bluetooth audio streaming for zero noise. Are you connected by the dock's audio out jack, or the GS2's headphone jack? I noticed better sound with the latter, but using BT is easier and sounds so much better.
2) Ditch Vlingo for CarHome Ultra. Extremely customizable and lots of great features, including up to 18 app shortcuts and auto-switching day/night themes. I love it.
You could make a profile in tasker that recognizes when the phone is plugged into a dock. Or you can make one for when it is rotated in landscape and plugged in. Then, you can enable an app to run, or have a list of apps that you can choose from. This is what I do with my phone and I don't even have a dock. It's awesome how much you can do with tasker!

I'd love to do that, unfortunately my car doesn't have Bluetooth audio. And I'm going from the dock's audio out to my car's AUX in. That's an idea, using the headphone jack, but I hate adding wear and tear.

Thanks again for the tip, that app rocks. In fact, it's better than the Photon's car dock app.
Now all I need to do is find some way to clean up the line noise and I'll be a happy camper.
Go to radioshack. Ask them for a ferrite core. Should be a ring of "ferrite" or iron. Make sure it's big enough to put the plug on your audio cable through. Push it through and wrap it around a few times and see if that helps. Also, running a separate hot lead and ground from your car battery to the cigarette plug you use should help. But the ferrite core should be easier/cheaper

call audio routing
Has anyone else been able to get call audio to route to the output on the dock? media audio comes out the port so I can hear that on my cars speakers but when I make a call it comes out of the phone speaker....
So, I've tried a variety of power adapters, USB cables, and audio cables, and the line noise remains. I'm going to try the ferrite core around the audio cable, but I don't think that's the issue--if you unplug the unit from power, the line noise disappears. So, I think it's just bad circuitry in the dock.
One would think that Samsung would have received complaints about this with the Epic dock (at least) and would have fixed it. Motorola managed to make a dock with excellent sound quality and zero noise, so it's certainly possible.
Otherwise, the E4GT is decent in the car with that Carhome Ultra app. Although, that doesn't really help with my decision between the E4GT and Photon, because with the Photon I could have the same dock app but also outstanding audio quality.
I can only assume the noise you are hearing is due to a Ground Loop/Hum.
It has to do with the fact that your power source is grounded to a different point than the stereo/speakers. the hum you hear is the difference in voltage's between the 2 grounds being represented as noise in the line.
for instance. I recently installed a new head unit in my truck, the unit has an AUX in and a USB port. If i plug my E4GT aux cable into the stereo and plug the USB charger into the port on the stereo - NO Noise. However, if i plug the phone to charge in another outlet (say, the cig lighter) then there is Line Noise everytime. The same principle applies when plugging your phone audio jack into any electronics.
Hope this helps shed a little light on the noize.

I hear you, except that I have two different docks that display entirely different behavior. Actually, I have two docks from the same manufacturer (Samsung, for the Epic and the Epic Touch) that have significant line noise, and one (Motorola) that does not. Note that these are all plugged into exactly the same power adapter and outlet and using the same USB and audio cables.
So, you'd need to account for the fact that the Motorola signal is perfectly clean in precisely the same circumstances while the Samsung's signal isn't.
I believe every word of it.
From what I know about Ground Loop Hum there are many weak links in the chain, and certainly some products behave better than others. The problem is still most likely the Ground.
One possibility would be that the manufacturer of the Moto Dock has included an isolator in the power supply line (or even in the audio supply line), and the manufacturer for the Sammys didnt.
My experience in this subject is with my Laptop/DJ setup making noise when plugged into audio equipment. when the power supply was plugged into the lappy, 60hz hum. Unplug it and it goes away. More than likely the problem was inside the computer or the power supply was just poorly manufactured as other models may not have the Hum. In my case i purchased a small isolater solved the problem. It may be possible to find one for a 12v car electrical system.

I actually hooked up an old RadioShack groundloop isolator to the AUX cable, and it got rid of the hum.
Something like this should work fine: http://www.amazon.com/GROUND-LOOP-I...QTRI/ref=sr_1_2?ie=UTF8&qid=1322958491&sr=8-2

Well, the salient point is that Samsung uses inferior components. It's possible to make a device that doesn't suffer from the problem, as Motorola has shown.

most times I've had line noise, be it from improper grounding or from cellular interference (namely from ground issues) the ferrite core fixed it. If it doesn't, the power isolation will. The reason the USB Ports on the head unit doesn't create line noiseis because it has isolation circuitry built in. The core is cheap. If that doesn't work, isolate power.

Okay, in the latest saga with the Samsung car dock, I noticed this morning that when I received a Bluetooth phone call, the TuneIn Radio audio I was playing didn't stop. Or, rather, it did stop once the stream buffer ran out, because I was on 3G and of course 3G data isn't available during calls.
Is this really how the Samsung dock works, that audio doesn't give way to Bluetooth calls? Or is that perhaps the CarHome Ultra app?
Still a bit frustrated with this aspect of the Epic Touch. The Photon's car dock works perfectly, including muting audio while on a Bluetooth call.
Grrr. I know, I know, if I like the Photon's car dock so much, why I don't I just stick with that phone... But seriously, Samsung, how hard is it to get this right?

I wonder if it might be the phone or the application. When listening to Sirius/XM radio without a dock, and I get a phone call, the radio keeps blasting away.
You don't stick with that phone because this one is superior in every other way. Its a minor issue. Why would you even have the aux input selected when there is no music playing? I have the noise too so I get it but ...yeah I just change the input when I don't need it.

Lg G3 hissing charger.

Hey guys i noticed something that I would like to point out and ask you about.
When using the G3 on battery i get no hissing noise whatsoever. But the moment i plug it in the charger supplied i start to vividly hear hissing noises. I noticed that a hissing sound also comes from the charger and i assumed that its normal because of the 1.8 amps flowing through the thing. Is it normal or do i need to hit up tmobile for a replacement charger?

you are welcome
I can tell you I've NEVER gotten any hissing sounds when charging any of my phones, or my wife's phones, whatsoever, over the years. Even charging them from a near empty status AND using them at the same time.
One time last year, I got a hissing/crackling sound when charging my Note 3 and it turned out our kitten had chewed a portion of the cable, right through the sheathing and exposed some of the wires. The cable was shorting out a bit and creating that hissing/crackling sound.
I would try and see if you can replicate the hissing sound when using another charger and/or cable, to narrow down whether it's the charger, cable or phone.
Hissing from the charger block could indicate a defect in the stepdown transformer or a short in the charging cable. Hissing from the phone could indicate a charging port problem. Hissing from the battery could indicate a defective battery.
Of course, this is coming off your description of a hissing sound, which might be similar to a crackling sound, in which the above still holds true.

Are you sure your g3 does not have the hissing sound while charging? At all?
Sent from LG Gangster 3
All mobile chargers will make a noise. That sounds comes from the electrical components, as they chance AC electricity to DC at lower voltage.
I dug out an old block charger and that gives off a hum, not a hiss, when I use it and also when it's just plain plugged in and not being used to charge or pass current. The hum do is very faint. I don't get any hiss or hums on my other chargers, whether charging or not.
And yes, all chargers are stepping down voltage, but cellphone chargers on a whole should not be hissing. The current is not much on a whole compared to other appliances that hum (ACs, fridges, etc) that are pulling more amps and current through that transformer. You might get an audible hum or noise when your phone is pulling the full current with a deep charge and even more so while deep charging and using it at the same time.
You said you're hearing hissing, which is not the same as humming. If your battery or phone is emitting a hissing charge, then something is up. As I mentioned in my earlier post, hissing from your phone or battery might signify a defective battery and bad charging, the cells might be overheating or so.
I'm not sure on your setup or so, but one cause of loud humming on transformers is "dirty voltage", or when you have noise on your electric lines. All lines have noise, but depending on your electric supplier, they might have more noise on the line and that translates into the transformer.
You mentioned hissing and not humming again, so I'm assuming it's actual hissing you're hearing. If it was humming, then I would say that that is normal under use and so forth. But hissing is something different, especially if it's coming from your phone!

Audio Issues when plugged into car First shortcoming I have found

So ive got to say this phone has been pretty much awsome for the past 24 hours but I have found its first major short coming wondering if anybody else is having this issue.
SO here is what happens. I happily plugged my note 4 into the aux audio jack in my car and then I plugged it into the car charger. That is when I get this really annoying electrical noise through the stereo system in the car. So I was like hum that is weird my note 2 only did that if the jack was not plugged in all the way. Well when a sound on the phone plays the electrical noise goes away completely and I hear the sound or song or whatever audio is playing crystal clear. Then as soon as no sounds are playing as if the audio card in the phone is not being used its like it shuts off and lets all this electrical noise coming through the charging system of the phone. Then if say a txt comes in the electrical noise sound goes away the alert plays then after the alert plays the electrical noise comes back super annoying. Can hear the alternator in the car through the noise as well. Make me wonder if it is a software issue of some sort because the noise goes away totally whenever any program takes over the audio driver and plays something through the sound card.
Anybody else have this issue? Try it if ya have not would be interesting to hear reports on this. I do not have bluetooth in my car so could not test it. I always raise the phones volume all the way up when plugged into the aux jack so I have more preamping to the stereo.
Thanks
Haven't tried on the note 4 yet but I did have this same issue on the note 2. But it was more of a white noise. Very low almost TV static noise.

I've had this issue with multiple different phones - I don't think it is the software exactly.
The only time that would ever happen to me is if I was using my aux cable AND had my normal AC charger plugged into it (using an adapter for the car that turned the "smoking thingy" into an AC socket.) If I used an adapter for the car that just gave me a USB port to charge it through only cable it would never happen.
And this happens consistently - haven't tried with my note 4 though yet though.
Try it without your charger plugged in.

I agree without the charger plugged in there is no noise at all. But it is strange that the grounding loop problem only occurs if software is not playing any audio at all. It literally goes away when something plays audio I can hear it go silent then the audio plays then there is another 8th of a second of pure silence then the noise starts again. Or say you are listening to tune in radio or something and a notification comes up. It will pause the radio program and then you will hear the noise for a split second then a sound will play silent again then split second noise then the radio will resume playing. So between the hand off of the two audio programs playing a sound you hear the noise really weird.
I agree the AC adaptor made noise for me as well on the note 2 plugged into an inverter. But this is just my normal 12 v adapter that never had a problem with the note 2. Will be interesting to hear what more ppl say with their 12 v adapters.
My power adapter above 1 amp makes a lot of noise. Had a 2.x amp for quicker charge. Had to revert to 1.x amp charger to reduce noise.

Adapter makes buzz sounds

Anybody can try plugging the boostmaster 18 w adapter in socket without plugging it into your phone and see if it makes a buzz or beep continues sound ...??
Alternatively you can remove it from socket and take it close to your ear and listen?
Thanks

From a distance, I haven't heard anything buzzing or beeping. All AC adapters make a buzzing noise if you put it up to your ear.
Same here. Cant explain it. I'm afraid of a faulty capacitor blowing up and damaging my phone. Perhaps just paranoia.
