Note 2 charger unbearable whining and wirring noises - Galaxy Note II Q&A, Help & Troubleshooting

My charger makes some horrible noises. I've had to resort to buying another one made for an s3 that charges slower when I don't need to charge it quickly.
Does this happen to yours? If not how can I send it back or request a new one from Samsung?

I was just about to search for this and came across this post, my Note 2 charger seems to make the same noises but only when the phone is plugged in & I THINK it stops when it’s finished charging, strange...
I could probably live with it but my main concern is the safety of it, I would also like to know if this is normal.

Anybody else??

I went to the samsung support page and contacted them. Within a couple of days they asked for my IMIE, date of purchase etc and say they sending me a new one.
I find it tends to make the noise as its either fully charged or almost charged

Thanks, I just sent them an email and I hope they do the same for me and the plug functions normally!
I've had to resort to charging my phone with a 1A charger I bought off amazon for the s3. Takes 4 hours to charge but I use it most often since I'd rather have the slower charge than the irritating whining noise.

Same here, must be the 2A going through it.

Mine has it. I just ignore it and now I dont even notice it anymore and the plug is about 1.5m from my head when I sleep.

Ipad 4 charger is 2A.
Sadly somebody owns one of those horrid things in my house
And the charger doesn't make any noise. Might be Samsung cutting costs or faulty first batch plugs?

No freakish noises here.
Its silent .

Very small zizzling sound while charging. Doesnt affect me anyways

The younger you are, the more irritating the sound can be.

Nope It's true. Try a frequencies app, you'll see that some sounds actually are only heard by younger age groups. As you get older you tend to loose the ability to hear higher frequency sounds.
Sent from my GT-N7100 using Tapatalk 2

Jep mine as well! Annoying whirring electro sound.. but only when disconnected from the phone, so no use to keep the charger in imo

Mine has this problem. Does anyone reading this with a Note II not? For me, it seems to get louder the closer the phone is to 100% charged, still makes the noise on 100% charge.
I phoned up Samsung and they said they're sending me out a new charger, so I'll report back when I find out if it makes the noise.

Battery problem

Hello,
I think something is wrong with my nexus. The battery charger from Samsung wont charge very good. When I use the phone while charging it doesn't charge. And I hear buzzing sounds when it charges. Normally I hear that only when my charger is plugged in the power but not in the phone itself. I run aokp B33. Do you know if something is wrong?

Your options are:
1) Change back to stock and see if that resolves
2) Change it to a different ROM see if that resolves
3) Get a replacement if 1 and/or 2 fails
Although, it does sound like hardware related to me...
The "buzzing" happens with most of our chargers if you're talking about the high pitch whine.
But how could it be hardware related.. I didnt do anything different.

Take the advice and run with it. If you don't help yourself troubleshoot then why ask? That is a very common troubleshooting method to return x hardware/software to factory specifications. You took it out spec putting custom software on it.
sent with 3g courage. better recognize.
Im just asking it myself. Take the advice and run with it? You were such a good help. Just restored my nandroid backup from a week ago and did a battery pull and I see it charging faster.

got the high pitch thing too with my charger... but I was told that isn't good for the phone... and I realized I had 35°-38° before the sound, and now 45° up to 50° while charging... I'm going to replace it, I just hope it doesn't cost the world xD I already gave samsung €600

Phone won't sleep

My phone won't sleep for more than 3 seconds. Its driving me insane!!! I press the power button, 1-3 second later it'll just wake up alone. Its SO frustrating. I've bought different batteries, changed ROMs. Everything. It just won't sleep! I wanna throw this thing out the window!! >=[ i cant take it anymore :banghead:
Anyone have these issues??
Also to note. My phones one of those infamous "always charging" issues and it won't charge via usb

Idk I bought t from someone on craigslist. How do I find out?
Sent from my Galaxy Nexus using xda app-developers app
Fast charge does exactly that.. charges fast lol.. its an option in most custom ROMs now.. eg. When ur gnex is connected to a PC in file transfer mode it doesn't charge very fast. But set it to fast charge and it turns off the connection to PC and charges almost as quick as a wall charger..
As for the warranty.. Samsung should be able to tell you or the original bill of sale that the guy from Craig's list should have given you
Sent from my Galaxy Nexus using xda app-developers app
Just call Samsung. Keep in mind if it is an international one you have no warranty.
Sent from my Galaxy Nexus using xda premium
Theres an option somewhere saying stay awake when charging
I believe you have a fault charging port, and best solution would be to send a warrant claim .
You could try to clean the charging port with a q-tip, and check if any of the pins are out of place.
Swype'ed on my CM10 Galaxy Nexus
Thanks guys! So if I call they'll know I'm not original owner right? And yes its unlocked gem international version
This phone has so many problems I literally can't take it anymore >=[
Makes me hate Samsung!

Overnight charging:is this good or bad

Hi, I have read here that some are doing this. What would be the effect of this on the battery life, as it usually takes only about 3 hours to charge to full. Thanks
Sent from my Galaxy Nexus using Tapatalk 2
There's no effect, it's fine. The phone knows when to stop charging.
agreed - I've been doing this with my phone every night since the G1 days with no problems
:good:
No overheating or whatever? Okay thanks. Nice to know that.

the charging micro will turn off supply to the battery when it is 'charged' so nothing to worry about at all
Yeah when the phone gets to 100% it will disconnect until 98% then start charging again.

Unlike me, the phone knows when it's had enough!

I think this is a base android feature, even my TF101 tablet does this when it's on the dock. It'll discharge until about 96% then start re-charging.

All of a sudden....

Gentlemen...all of a sudden, this gadget is taking 10 times more time to charge. Till 3 days ago...it was getting full charged within a couple of hours from 0-100%
All of a sudden, it's like 6 effing minutes for 1%....whats wrong? Have tried removing nd re inserting battery/tried charging from various plugs-sockets...:banghead:

If Your phone is running battery intensive apps its gunna take longer to charge. For instance...if I'm running navigation with music and the screen is on high brightness I will still LOSE power while I'm charging on my trucks USB.

Something wrong with your charger. Try another charger, if it charges ok with another charger then obviously your charger is at fault. Get a replacement from Samsung.
Thanks mate..will try that

Make sure you use the charger provided. The note 2 uses 2mA. Most phones use 1mA.

Make sure you are using the same cable as provided. One time I changed to a different and longer cable and it took forever to charge.

+1, the longer cable also not able to withstand charge while using the phone...

Note 2 to hot when recharge !!!

Hi..i see that my note 2 is to hot on upside on
display when i recharge it.
Some one else have the same issue?
I use a car recharge because i'm always on the truck...battery monitor don't see any problem..
What to do?is dangerous for my note?must stop recharge? I used about 2 times every day for full recharge and in this time i use internet.
Sent from my GT-N7100 using xda premium
Is it Chinese?
Is it from a trusted company?
Did you noticed any battery drain or lesser battery life or longer charging time with normal charger?
Possibilities are the car charger isn't optimal for your phone.
Buy from a known store or a Samsung dealer or some other trusted or reputed store.

Try the charger with some other phone.
You really need to charge it with a wall charger or pc to property diagnose the cause.

Install "Battery widget Reborn!" or any other app that has such feature - and tell us how many degrees does the battery heat up to. If it's over 40-50 celsius, there's definitely something wrong with it.
