As I stated earlier, the problem is not fixed by changing rom, all non–Samsung Roms don't notify of overvoltage, and however if you type *#*#4636#*#* in the dialer you will see that it is still there
[Galaxy S II Q&A, Help & Troubleshooting] b3ssen:
Solved!

1) Shut down your telephone and remove the battery

2) Clean your usb-port with a little brush (I used a tooth brush) for a couple of minutes

3) Move the usb-pin of the usb-port in your phone to the centre of the usb-port (I used a sharp knife)

4) Put your battery back in and put your phone on!

It worked for me!

Good luck with the problem!

I had same problem until recently. Cleaning the USB Flex with a cotton seems to do the trick. But it would nt connect to PC any way.

I sent to Samsung For replacement of USB Flex. But they refused to replace under warranty stating it is water messed up. However, when I pressed a little they did replace it.

So I suppose Samsung says eveybody the same thing. Only adamant people get it replaced ;-) (Strange customer Support by Samsung)

What do you mean exactly with this?

Samsung refused warranty because of water damage for me too!
[Galaxy S II Q&A, Help & Troubleshooting] thez3ro:
happend to me a couple of times in my company car... with an original samsung galaxy s2 car charger... :/ did not use it for a while now and went to aokp rom...
[Galaxy S II Q&A, Help & Troubleshooting] caanda45:
Ugh, I have the same issue, mine works at least, I have ordered the part and will change it. Mine is definitely water damage, should have listened to my wife on where I charge my phone....doh!!!!!

In desperation I tried this for the hell of it....

And it worked!!!!!!!!!

Okay partially, it charges okay and the error message is gone, but I can`t connect the phone to the computer to side load. It is not recognized. My best path is still to change the part or stay on the rom I have on forever!!!!!

Another lessoned learned is that I have been using a HTC usb cable that has been working, but in very close inspection it is slightly different and over time that has bent the phone connector down. Once I bent it back with the knife the charging started to work properly and the error message disappeared. But the connection to the computer would not work any more....oh well I will change out the part and hope that solves the issue!!!

Also for people not having the ability to connect to the pc/mac use airdroid. In google play and as long as you have a wi-fi connection it allows you to connect and transfer files to your phone and pc etc....real nifty program. This will allow me to flash till I fix my phone!!!

Hi guys, it happend to me too , after i flashed ICS so i started flashing other roms, but didn't work , i recived other messeges, ( my phone was not connected to any thing and a message said it was .. and many others) so when i wanted to get it back to warranty i installed the stock gingerbread 2.3.3, erased the flash counter and then i plugged my phone to pc and updated to ICS via Kies , and then hasn't appared anymore , and the battery life is way better than any ICS rom i tried... I hope my comment is helpfull and sorry for my bad english. :D
[Galaxy S II Q&A, Help & Troubleshooting] ldmelo:
Things are messed up here.

I think you guys are having different issues with your phones.

If you get this message (voltage too high) after pluging your phone to the original samsung wall charger, than you have some serious issue and I can't tell you much about it.

But if you get the message when you use a car charger or some generic wall charger, then it is unlikely that you have hardware issues. I tell you this because I tried different phones running stock ICS 4.0.3 and same thing happens to them. In my tests I never had a problem with the wall charger (samsung), but I have 3 car chargers, and I get the "voltage too high" message with two of them, the other one works fine. It is interesting to notice that one of the car chargers has 2 different cables, and the problem only happens with one of the cables.

So, since I tried two different phones, I think it is not related to my phone. It is something related to the s2 and the ICS rom. I think newer roms are just smarter and are poping up the message to warn you about voltage inconsistencies which previous roms didn't. By the way, the original samsung charger provides 0.7A, while most of the car chargers or generic wall chargers provides (or claim to provide) 1.0A. Don`t give me lessons about voltage and current, what I guess is that this 1A chargers could easily get above some voltage threshold level and trigger the message.

Changing cables worked for my car charger because it changed the way the phone detects the charger. Typically there are two different connections for charging android phones: AC (wall charger, car charger, etc) and USB (PC, etc). To tell a long story short, USB standard only provides 0.5A while a wall charger can provide more than that. The phone knows if it is connected to a standard USB or to a charger, because in the second case people conventioned that two of the USB pins would be short-circuited (either on the cable or inside the charger itself). If the phone detects that it is connected to a standard USB port, then it will drain a max of 0.5A so it won`t fry the PC`s usb circuit. On the other hand, if it is connected to a charger it will drain more than that.

To know how your phone sees your charger, just go to settings->battery. If I remeber it correctly it will be either "Charging (AC)" or "Charging (USB)".

So, if you just want yo get rid of the problem, you can try changing your USB cable or charger, so that you change from AC to USB charging. It will probably work, but it will charge slower.

You can also try getting a 0.7a car charger (not tested!) or using a little AC inverter and the wall charger in your car. This solution provided me a very fast charging in my car and got me rid of some interference noise I was getting while playing music with the phone connected to my car aux input.
[Galaxy S II Q&A, Help & Troubleshooting] E-Nigma:
Yep out of the blue, it began happening to me last night. Had the handset since November but installed official ICS last week. Tried cleaning and wiping the connects both on the USB lead and the handset. No difference. I can't even back my phone up to do a factory reset which is annoying.
[Galaxy S II Q&A, Help & Troubleshooting] meirionwyllt:
Me too. I have the same problem, and it has come since I flashed to a sammobile.com firmware (ICS Orange UK 4.0.3) using Mobile ODIN, which I bought from the Google Play website. When I installed Mobile ODIN, it went off and downloaded the correct Kernel for my phone (Galaxy S2), so I believe the Kernel to be correct.

It seems like something weird is sitting in memory that blocks the USB port homehow. The reason I say this is because if I plug in the charger then the phone doesn't recognise it, however, the moment I reboot the phone, the USB charger is picked up straight away when the phone comes back up.

Also, after finishing charging I unplug it, and that's when the annoying "voltage too high" appears. BUT, they disappear the moment I reboot the phone once more.

So, in my case, the above info makes it unlikely that this is a hardware problem. In my case it looke to me like a software problem.

I have tried two AC charging and USB charging, with different cables. I find it very difficult to believe that I have water damage, because I've only had the phone a month, and have been looking after it.

Although the "voltage" messages have only started to appear since flashing to ICS, I did have some USB connector problems before, when I was on 2.3.6 unbranded. (In case you're wondering why I opted for a branded Orange phone when moving to ICS, it's because with that I get Orange Signal Boost, which is a life-saver in my area)

The problems I was having with the USB connector was that the phone wouldn't recognise when I was plugging/unplugging the charger. I had to reboot the phone a couple of times for it to recognise that there was a charger plugged in. And the same when unplugging, the battery icon still a lightning through it, until I rebooted. Also, Kies stopped recognising the phone when plugged in to a PC (Windows gives the "USB device not recognized" error). After flashing to ICS it is even worse in this respect - not Windows doesn't pick the phone up at all.

I really don't think getting an USB board would help in my case. Plus I don't really want to mess with the phone on the hardware side, because at least with messing with software you can go back to stock ROM to keep the warranty alive.

Of those who have this problem, has anyone else flashed using Mobile ODIN?
[Galaxy S II Q&A, Help & Troubleshooting] E-Nigma:
Thought I'd update you all. Well today for some reason it's decided to start working again? Upon connection, it says at the top of the device screen "connecting as media device". Which I don't think it ever said before. It used to just say something like "MTP initialisation"? Anyway, was able to do a backup via Kies then I ran factory reset.

Still no Virgin in the network selection list but that's hardly important or life threatening. At least the phone is up and running again now though (for now). PC detecting and charging it ok and no "voltage to high" message anymore. Let's hope it stays that way.

Random yet volatile :-l

[Galaxy S II Q&A, Help & Troubleshooting] GeordanUK:
This started happening for me this morning shortly before setting off for work, all of a sudden my phone kept making the plugged in sound and kept repeating it for about 10 minutes along with the "Charging paused, voltage too high" (which is really annoying when you're wanting to listen to music) it stopped after a while though.

Later on in the day I plugged my phone in and let it charge for a while, upon removing the device my phone started the whole charging paused thing again, but this time it hasn't stopped, I noted that with my phone still plugged in the screen had an odd flickering to it (which has since stopped)

Once again, like other users this is a problem that has emerged since putting ICS on there, this is the Unbranded UK ICS

Sometimes after fully charged, the signal of my S2 dies and only returns after a reboot.

I guess that it's is possibly related to this "overcharge" issue.
[Galaxy S II Q&A, Help & Troubleshooting] caanda45:
Got my usb/flex cable installed today everything is back to normal!!!!!!! Had a couple of issues on install, lost sound and it was just a temperamental ribbon cable once isolated and corrected all is back to normal. Phone is fixed and operational!!

However no water damage was detected, but could not connect to the computer, so that is fixed but perplexed on what the issue really was/is...time will tell if it comes back or not!!! What I am going to do is use the physical connection as little as possible and transfer files wirelessly using airdroid app.
[Galaxy S II Q&A, Help & Troubleshooting] bunnybash:
I bought the Anker batteries on ebay which come with their own external charger - so between transfering files via wifi and charging in an external battery, i only use the usb to dock my phone in the car!!

Well an update, the sound and speaker are kind of f`ed up since my repair....sound is in and out on voice calls, it is okay over the bluetooth...any ideas or thoughts on this?? I think I have to send it in for repair....ugh......

check the connections of the ribbon cables to the mainboard... i know the cables are a bit tricky to actually get to fit on... if they are not seated properly it will go awry I imagine.

[Galaxy S II Q&A, Help & Troubleshooting] GeordanUK:
I've found that by deleting your phone cache in the recovery menu it makes the battery work fine again, which made me figure it definitely wasn't a Hardware fault, as I said in my previous post I'm running ICS, the only problem I face now is getting off ICS as my phone has a fit when it's turned off and in previous efforts of trying to flash to CM7 temporarily have failed. Going to try MIUI to see if I have more luck with that.

The same happened to me. After the I flashed the first custom ROM and I pluged it in the charger in my car the High Voltage error came up.

The charger was the same one I used for my ex-phone Nokia N97 and it was a 1000mV output.

Now I bought another one that's 750mV output and it doesn't come up anymore (so for me it was the charger). Regardless to say I changed and the ROM but it wasn't the ROM ..

This is the same problem that we all had, the described fixes will work for you. Did you even read the thread?
[Galaxy S II Q&A, Help & Troubleshooting] jellywobbles:
I have just read every post in this thread, and its a mess!

What described fixes will work? There's so many of them? Many contradict each other. ;)

There's those that suggest changing the USB port on the SGS2 - some have done just this, only to find that the problem didn't go away at all!

IMHO it would seem that you need to use a "stand alone" USB car charger (& not the ones with an integrated cable).

I get the "voltage too high" message with my car charger that has an integrated cable, yet using the Samsung mains charger or charging from my PC, the problem doesn't arise.

The guy here talks a lot of sense

This is the route I am going to take & will post back after testing etc.

Cheers ;)

Hi - can you post a link to the 750mV car charger that you bought?

Cheers :)

UPDATE: Let my battery drop to 30%. Drove into work with exact same charging cable (with integrated cable) & no problems!

Most definitely NOT a hardware issue!
[Galaxy S II Q&A, Help & Troubleshooting] mast3rboy:
Yes i have read the thread but some users talk about high voltage when the phone is connected to charger. My device works good when it's plugged in . I will take it to warranty and i hope they will give me another one.

I've suddenly developed this issue after going from a custom ROM (hydrog3n) to stock ICS (LP8) so iI fail to see how it could possibly a hardware problem. Yesterday my phone was absolutely fine. Flashed the stock ROM, woke up and I now have this issue.

I've the exact same problem. Happened to me last night. I was on stock GB rom until i flashed Wanamlite a week ago.

While the charger is plugged in it'd prematurely notify charging is full/voltage to high. Also after disconnecting from the charger it constantly displays 'Charging paused. Voltage to high' message'. Annoyed :mad:

As I said in an earlier post, its not a hardware issue with your SGS2 - its a charging issue.

This thread is about issues concerning "charging paused, voltage too high" messages and not " Can't charge my GS2"

Suggest that you start a new thread with your problem instead of hi-jacking this one - you'll probably get more help!

Had the same problem with a 1700mA/h Mugen battery (after having accidentalmly completely discharged it -falling asleep on my phone while messing with it in the dead of night :s).

It's probably just a coincidence. My guess is that the internal circuitry of your battery is dead.

Try replacing it with a "genuine" samsung battery (no other brands, ever !) and see if it persists. I'm confident it'll be gone once you change it :)

Post a logcat if you can, and the output of " dmesg>>/sdcard/battlog.txt " (without quotes of course. You'll find the file on your sdcard under battlog.txt but you can name it whatever you want, as long as you post it or copy/paste its contents here afterwards :))

OK guys i have some good news.

First of all IMO It has 100% nothing to do with hardware, so calm down.

The problem seems in a software bug.

I had the same problem whole morning today, and just now managed to fix it . First of all i tried to clean my usb hole with a toothpick, There was PLENTY of dusts and grease!!!! (Have to warn you it is a risky procedure)

After message appeared again i realized that it had nothing to do with dirty usb port.

Second thing i did , i plugged usb cable to computer,

on a phone went to USB Computer Connection -> changed it from MTP Media device to CAMERA PTP (waited for few seconds for PC to find drivers , typically pc didn't find a correct drivers :) so i unplugged it )

Then plugged it to pc , changed it back to MTP Media Device. Unplugged & TADA !!!!! problem was sorted. SO FAR NO MESSAGE APPEARS

What might cause a problem ?? Recently i installed bunch of apps it might be something to do with it:

Shot Control, Wifi Manager, ClockQ Pro, Remote Desktop, Thumb Keyboard, Arms and Legs, Copilot Live EU Full, Alarm Clock Ultra, Lucky patcher, SuperSU

Version: IC 4.0.3

Baseband: i9100XXLPQ

Kernel: 3.0.15-i9100xxlpq-cl223505se.infra@sep-94#3

explanation for the Charging paused. Voltage too high problem

i had this problem on 2.3, read a lot of post.. some say hardware problem, some say software...

on 2.3 cleaned the usb port etc.. fixed the problem....... for maybe 1 day :(

after a while, rebooting, remove battery, the problem went away.

Upgraded to ICS and never had problems for about a month.... then yesterday the problem came back "charging paused voltage too high".

We can rule out software problems after reading a lot of post, it's the hardware...

The explanation :

I charge my phone at work, on the road and at home... all using different micro USB cables.. of different quality. There seems to be a micro millimeter difference in the connections in these cables. After a while charging and in and out of these different USB cables the USB charge connector gets damaged or something. (poor built quality?)

This is the problem, the USB lines in the connector gets connected through touch or air,dust, dirt exchanging volts, and give of a higher voltage to the phone. If the you charge the connectors on the USB port "sync up" and don't give any error.

I tried to gently pull the connector up or down with an USB cable and the problem goes away for sometime...

Looks like i have to bring it in for warranty... :(

Fix for Charging Paused, Voltage too high

HI All:D

My issue was that my phone would come up with an error message every 2 minutes with "Charging Paused, Voltage too high". It also was very difficult to connect to comp via USB.

It has something to do with the micro usb port on the phone.. i noticed the metal plate bit in the phone micro usb dock was pushed all the way to one side. Using a pin i moved this back to the centre and removed the lint.

I have no issues now =) I think it may have something to do with me not removing it from my car charger properly.

Let me know iif this helps anyone:):):)
[Galaxy S II Q&A, Help & Troubleshooting] tricurious:
I had a couple of problems with my phone and had to send it to service center eventually.

i. Voltage too high/Charging paused message would popup every couple of minutes in the beginning and then it stopped. However I was unable to charge the phone with the adapter. Instead I used the USB cable to charge it up wherein at approximately 85% charge I'd get a notification that the battery is full. This 100% battery charged notification in the status bar will then remain persistent through out.

ii. When I'd shut down the phone, I'll get a big battery charging indicator even though the phone is not connected to an adaptor or usb cable and will also flash a high temperature warning message alternatively.

iii. Also while the phone is shut down it wouldn't boot. But if I connect the USB cable, it would boot up.

iv. I wasn't able to connect it to PC using the USB cable, windows would notify that the device isn't recognized. Also the phone would display "MTP connected or initialization" all the time in the notification bar.

Yesterday eventually, I went to the service center and they said that my USB circuitry was liquid damaged. I had to pay money to get it fixed as liquid damage is not covered by Samsung.
[Galaxy S II Q&A, Help & Troubleshooting] Ba7rani123:
In electronics conductors usually has resistance when current is change suddenly, which means if u turn off the power supply it becomes a high resistor they suck all the voltage and u get a very high voltage therefore theres something called a voltage regulator which protects the system :), So dont worry abt it :) unless u want to ask a more experienced person.

So Its a software bug I think where it checks the voltage of regulator instead of the voltage of the current actually going into the phone.

Edit : It may also be caused from a dirty USB port :). Search for how to clean USB port.
