Noisy Mains Charger - Galaxy Note II Accessories

I noticed this morning a strange hissing noise which at first I thought was coming from the phone. This was when I was using the phone whilst it was plugged into the mains charger.
I removed the cable and the noise stopped. I plugged the phone into a USB port on my PC and there was no noise this time. So I checked the mains charger that came with the phone and sure enough the noise was coming from there!
It almost sounded like there was a fan inside, a very similar noise.
Has anyone else experienced this or can you recreate this?

It also happens to my charger, you can feel comfortable there are no problems

I do not have this charger but from your description it sounds like normal switcher noise.
The charger likely uses a switcher for dc-dc conversion. When not well designed they can have an audible noise. Usually it is not a fault and no reason to worry.

Thanks for the info guys

i hoped i finally got rid of that noise with a new phone, but my note 2 charger makes noise too.
just like my LG O2X charger and Galaxy Tab 2 7" charger.
yet all my other chargers are capable of being perfectly silent.
it's loud enough to give me trouble sleeping, and i'm used to sleeping next to a noisy PC.

I don't have a Galaxy Note 2 yet, but my original Galaxy Note's charger makes noise, as well. I believe because it has a high mAH recharging, because I use as an extra charger an old blackberry charger (with a long long cable xD) with only 500 mAH recharging power doesn't make any noise. I don't know if it has anything to do with how much voltage is flying through the charger has anything to do with it, but:
*Samsung chargers make noise.
*Other chargers I have don't.

All the chargers since the SII's have emitted some noise when there is no device plugged in. I don't really mind honestly.

Using nokia phones since 2002 i have to say most of them make that sound, dont worry

I got my SGNII at the weekend, and I have a very noisy charger, to the point where, as it is close to my bed, it wakes me up when its finished charging. However its only noisy once the phone is fully charged. Unplugging the phone once charged means the noise stops, but it also means my phone has been running on battery for 6 hours before I get up.
I think I will switch to a different USB charger that doesn't sound like a mouse being tortured

No Problem
Never faced this issue ever. Maybe faulty chargers i guess

any one noticing a weird humming sound when charging ?

just plugged phone in and theres a weird humming sound coming from it also doesnt seem to be charging it was fine before 2.3.6 update any one had any issues with the update ?
its not the phone its the charger it self.. im fed up with all these newer devices doing it, my virgin modem + note + razor chargers all hum and its really annoying
I hear a high sound from the charger but only when the phone is not connected.
CU
I found mine did the same straight out of the box so I don't use the charger, I use my N900's charger instead which doesn't make any such noise.

Galaxy S4 wireless charger

Do you guys think it would work with our Note, it looks really nice and clean, I might have to get it.
Like the one seen here
https://www.youtube.com/watch?feature=player_embedded&v=NsNot054HV8
Well considering that it'll need the battery cover then I would have to say no it wont work. Maybe you can email them and ask if they can make a battery cover for the Note 2.
I actually agree with the comments stated on the video.
It's just another cool gimmick that is just nice to have.
It doesn't charge faster and it is harder to use your phone.
I recently set up wireless charging on my wife's Galaxy S3 and she hates it for the following reasons:
charges slower than the USB cord
Difficult to use the phone while charging. With the USB cable, you can plug it in and continue to use the phone in your hands.
The Qi charging plate (a Nokia unit) has a LED light to indicate when the phone is being charge. That light is kinda distracting when you're trying to sleep at night.
Since the phone has to be charged face-up, the phone's LED notification light is another distraction at night.
Makes me rethink pursuing wireless charging for my Note2.

[Q] Charger makes weird buzzing sound

Hi all,
Several days ago I got a brand new LG Optimus 4x HD. Last night I plugged the phone to charge and went to sleep. This morning when I unplugged the phone, a weird buzzing sound was coming from the charger. The phone was charged 100% and seems to be fine. Since the LG charger looks a bit cheap compared to other chargers I have seen (made in china by Sunlin T_T). I have charged the phone several times by now, but noticed the sound just today, I dont know if it was there before. I decided to see if the charger from my previous phone (Xperia mini, used for over a year and still working fine) will make the same sound and it actually does! Its alot quieter and I could not hear it until I put the charger to my ear, but its there. Also with both charges the sound continues for a while after they have been unplugged from the wall socket.
Should I be worried ?Note that the warranty of my phone does NOT cover the charger itself, so I cant replace it. If needed I will change the charger with a Duracell or Energizer charger, since here its next to impossible to find separate original phone charger.

the sound is normal. it happens in almost every AC to DC step down transformers. The sound should come on a short while after you unplug the phone, and slowly go away when the charger is unplugged. It will also stop when you plug in your phone.
you can do a little experiment here. When you hears the buzzing sound, switch off the charger or unplug it. Then without any power, plug in your phone FAST. You will see your phone is getting charged for abit, then it stops together with the buzzing sound.
anyway you shouldn't leave your charger switched on when its not charging, its a waste.

Thank you for the info. Now I noticed that the charges makes buzzing sound only when the phone is 100% charged or when the phone is unplugged from the charger but the charger is still plugged to the wall socket.

[Q] Battery drain while using the phone connected to wall charger

Hi all, I have never experienced this kind of wierd issue with any of my past phones. When i would play games or say watch a movie on phone,( my last one was Htc One X), i would usually connect it to a charger so that the battery keeps charging slowly, and it worked with each of my past and even my gf's galaxy s4. But with XZ, the battery keeps continuously discharging. Anyone got any fix for this? With the kind of weak battery XZ has, it is a highly needed basic feature. I even tried with a 2A S4 charger, but to no effect. I even tried the modding of usb cable by shorting the data wires (the green and the white wire cut and insulated), still no improvement.
I have been using existenz v1.5.5 kk, and i can see that there is an option of fast charge in performance control. But turning it on doesnt make any change. Does the kernel not support fast-charge?Can anyone share any insights? It feels stupid to have to lay the phone down letting it to charge by itself olny to get all discharged within 3 hours.

Charging is really a problem for XZ. Anyways, shorting the data wires won't help, try switch to a stronger cable that's capable of transferring larger amount of electricity when you're using the 2A charger (many of those cables aren't able to transfer enough amount of electricity).
Also, when your phone is really fully loaded and became very hot, just as when you use it for navigation in your car under the sun, the charging speed will decrease (I don't even know why). The charging speed decreases either when you're touching the screen or when it's hot.
Anyways, try better cables first and see if it helps. The docking system is also likely to charge faster.

I used a whole bunch of cables. The HTC one actually works as an anti-charge cable lol, it eats up battery even when the phone is left on charge unused. I had high hopes with the S4 cable, which turned out to perform same as the stock Sony one. Guess I have to live like this..

Sorry to hear that the cables you tried all failed. Did you try using the docking system? They should perform better though.
I mentioned switching cables because I had a "anti-charge" cable before, lol. I did some research afterwards and finally got some 22AWG cables and they really made a difference. It's said that they're capable of transferring 3A electricity and it's really different from all other cables I've used. They're just about $2 each because they're handmade, I can give you one if you wanna have a try.
Also, charging by AC power should be better than using the power of cars' lighter. I'm using my docking system with the SONY stock charger w/ ac power. Never disappointed me.

Dude you might not be able to give me even if you wanted to.. I am in india and the shipment cost will be excessive. Thanks a lot btw.
I flashed Carbon KK rom and the charging is comparatively better. Atleast it doesnt drain while i use the phone for browsing etc, connected to a wall charger. But if I play games or watch videos on speaker, it does to some extent. I bought one more charger, a Nokia made 750 maH charger (AC 20N) which again is wierdly same in performance compared to both the 1.5A Sony and 2A Samsung. What I think is as you said, the wire makes all the difference. A 2A non detachable is the need of the moment for XZ it seems..
Anti-charge cable?
Xperia™ Z (C6602) with Tapatalk
From my experience usually Google Play Services is the culprit for hot phones and battery drain. What I did when on stock 4.4.2 was i uninstalled updates for the services and my battery life improved by a lot. Although it does come with the downside that some apps like youtube won't work with the older version (easy work-around by using chrome to go to youtube instead =P)
Since I own that phone, I've been facing the same problem of slow charging speed (actually discharging when using some applications)
The more problematic case in when I'm using the phone in car when driving even if I'm using a powerful car charger (Anker).
In the past I also have tested number of diffferent charger and cables (including original Sony car charger) without seeing *any* improvement.
Recently I've decided to took time to make a comparison test with a colleague Nexus 5. We have connected it in my car to the same charger and used in the exact same configuration (Waze navigation app running) for a one hour drive on the same work->home daily path where I use usually my Xperia.
The measured results have shown for the Nexus a 30%/hour increase of battery level opposed to the Xperia 10%/hour decrease I'm facing every other day.
Later, using "Android tuner" application battery monitoring tools, I've been able to measure that, even when using a 2.2 Amp capable charger, the Xperia isn't able to "suck" more that 700/800mAmp input current most of the time.
To go further I've asked in the french forum where I've posted those figures if any people had been successful to have the Xperia battery level increasing in the same configuration. I have got only answers of other people acknowledging having the same problem as myself.
Then I've also asked people in the "accessories" section of a car owners (Toyota) vehicle forum: found people having the same issue are also owning Sony models.
Also asked another colleague who who owns a Xperia model Z1: ditto.
I definitively start to think that there is a defect is a in the battery charging regulation system of the whole Xperia range.
BTW: I will be very interested if anyone using an Xperia Z in car with navigation application running without those issues could post details about his charger brand and model, and how much battery percent/hour increase he his actually getting with that setup.
Sorry for the long message and thanks for your attention

[Q] Morse Code Sound While Charging?

My Note 4 (T-Mobile version, obviously) is making a very faint rhythmic beeping sound that almost sounds like Morse Code when I place it on my wireless charging pad. The phone charges just fine and doesn't get hot or anything, but the beeping is very annoying when I try to sleep at night. The beeping stops when I take my phone off the charging pad, but starts again as soon as I put it back on the pad. It still beeps even if I turn the phone off. I am using the official Samsung wireless charging back cover and official Samsung charging pad. Is my phone just transmitting my personal info to the NSA through Morse Code while I sleep?
Thanks,
Jeff
Meth.. Not even once.
My nokia wireless charging pad's wall wart makes beeping/squeeking noises that I thought was the phone at first... might give that a listen if your pad has a wall adapter...
^^ what he said.. I've seen that with quite a few wall adapters so it's not a stretch to imagine it could happen with a charging pad, but put your ear to the wall adapter & see if it's that. In my experience it's old/cheaply made adapters but it could just be a manufacturing fluke with your particular unit
It's definitely coming from the phone or plate (hard to tell which one is making the noise). The wall adapter/cable I'm using are the genuine Samsung ones that came with the charging plate, so they shouldn't be cheap junk.
I'm pretty sure my Note 3 beeped too, so maybe it's just a characteristic of this plate?
It's not your phone, it's your charger.
I have two Tylt Vu chargers and they BOTH make very faint beeping/whining noises when charging my phone, plus the wall adapter makes a constant whining noise, too. It's just ****ty parts used in the chargers, nothing you can do about it.
