Hi guys,

So i have a s2, The fault is sometimes it will charge ok other times when you unplug the charger it will carry on charging. It was on gingerbread.

Now i installed stock ICS on it and it does the above still BUT i always get a message - charging paused - voltage too high.

So i done heaps of research on this very forum and found different things to try, Below is a list of all the things ive tried so far........
1. software flash (original)
2. clean charging port and battery pins
3. Move the pin in the charging port away from the sides
4. Replace the charging port board completely
5. calibrate battery (by app and manually)
6. Tried rooting the s2
7. Installed VK ROM (23.06.12)

SOLVED

Hi, yes i did that is why i joined on these forums. Ive tried all solutions on that thread + more. The last solution indicating to clean charging port doesnt effect me as ive just fitted a brand new port!.

j4g3d

I have just rooted my S2 for the first time and the problem has gone away. I wont keep my hopes up, i will wait a few days and see how it goes. If the problem comes back my next step is a custom rom.

n7plus1

please check back and post your experience.

j4g3d

What i did was, reset to factory settings and then root the S2. Unfortunately the error message i initially experienced has returned.

The only difference is when i remove the charger, the phone stops charging as it should. But when the battery drains down i get the message voltage too high.

I cant say if its hardware or software related or BOTH....yet. But i wont drop it till i find out exactly whats causing it. I will try a custom rom tonight and see how that goes.

j4g3d

I've installed VK rom and ive calibrated the battery. I let the battery run down to 12% and then charged back up, completed that step again.

Its been 17 hours (longest ever) without the problem returning. When i charge it, it charges, when i disconnect the charger it stops charging. I get no voltage too high messages SO FAR.

Im not getting my hopes up YET. But its looking good. So if it fixes the issue i still cannot tell if it was a hardware or software issue or BOTH. But those want to try fix there phone you can follow my steps.

n7plus1

mine was like that too up until it now doesnt turn on. been dead for almost a week now. waiting on a new charging usb port. hopefully when i replace that itll turn back on.

j4g3d

Just an update to say the problem still has not returned!!!

Should i consider myself lucky?
should i expect it to come back?
Could the new rom be 'hiding' the voltage too high message?

Either way the charging also works as it should. It has never been working perfect for this long before.

n7plus1

interesting...good to hear your problem went away. im starting to question whether or not the usb connector port will actually prevent the phone from turning on if its bad.

j4g3d

They are so cheap so in your case its worth a try isnt it. Do post and tell what happened as i am interested in your case too.

bgmnt

Even I am facing the same problem since the recent ICS update. its so irritating.. Kindly can someone fix this....plzzzzzzzzzzzzzzzzzzzz

n7plus1

ill be sure to.

j4g3d

Been almost a week and 4 or 5 fully charge cycles.

Problem SOLVED.

bgmnt

Great. How did you manage to solve. Recently I tried flashing with Official Stock ROM, but still no use. I still see the annoying message "Charging paused...Voltage too high", and the battery continuously flashes, and it shows it is still charging even when the charger is disconnected... It would be great if we can know, how did you manage to get it solved..

cheers

n7plus1

sounds like you both need to have the USB connector port replaced. sounds like you have a fluke with teh new rom...the problem will probably come back.

n7plus1

received my new usb connector port this weekend and installed it...still nothing...

mystvearn

I also have the same problem since yesterday. I am on stock software and have never flashed before.

How do you do no.
2. and 3?

andyroo77

I have this problem too on Galaxy S2 running ice cream sandwich on T-Mobile UK. Very annoying message and beep.

Was running ice-cream sandwich happily for a couple weeks. Started the day I had to jump out the shower and take an important call with wet hands. I suspect a sensor inside detects moisture and causes this error message so you send it for repair and are told warranty etc invalid due to water damage. Phone works fine otherwise. I did have the phantom car mode issue, also annoying but related to the charge port being grubby or something. This one drives you up the wall. Will have to root and see.

To the original poster who 'solved' by rooting and installing custom ROM, could you install stock ics and unroot and report if still getting the error? Big ask I know.

mystvearn

My problem suddenly disappeared after two days. No idea why it occurs though, did not do anything.

bluejava2

For me, changing chargers did the trick. I bought a Samsung OEM micro USB charger and haven't seen that "voltage too high" message for 3 days now. I am rooted and on ICS 4.0.3.

j4g3d

Get a tooth brush and gently brush the contacts, And as for #3 - get any thin object (flat end screw driver..ect with phone off) or any plastic object with the phone on and gently bend the charging pin inside the charging port of the phone ( at your own risk ).

Mine used to disappear and come back, it gets your hopes up but then your hopes get hit again when the message appears. Chances are your error message will come back.

I also tried changing chargers, Didnt solve for me.

To sum up my issues, i originally had gingerbread, i updated to ICS (without root) using kies, and after 1 day i got the message come back. It made me ROOT my S2 and put the custom rom on. Solved now after how many days... 1 or 2 weeks!. Certainly looks like it wont come back.

j4g3d

Unlucky, i guess there is no other option for you...

Mine going strong, approaching 3 weeks now.

Advice to all is, we all might be getting this 'voltage too high' message for various DIFFERENT reasons. The best advice i can give you all is try the free methods first then the least expensive to the most expensive.

I think its a combination of a hardware and software fault personally. If you buy a USB port board, replace it then reload the software pref by rooting. Then calibrate the battery.

MREMERSON

my phone fell out of my pocket on to the sidewalk in the middle of a heavy rain storm. Someone found it minutes later and brought it inside to the restraunt i was eating at and found me. Miracle! I let the phone dry over night with everything unplugged and a fan on it. Turned it on in the morning. Everything worked fine. However i did start getting that "charging paused message- voltage too high"

after i cleaned the charging port. There was a bunch of lint and junk in there, and after that...no more message no problems!!

hopefully it stays that way? FingerS crossed.....

motownwill

I've had it with Samsung. First all the firmware update refusals with the original Galaxy and AT&T, now this nonsense? Time for HTC maybe.

Nagrom

I've been getting this error, but at a weird time. When my phone is plugged into my car charger, and I switch off the engine BEFORE unplugging it, then I get this error. No other time do I get it.

Strange

Well guys, if you want it fixed follow my steps in the original post.

Obviously starting from the free ways first.

Of course though, i strongly think this error can pop up for various reasons... Corrupt data, dodgey charging board, water damage, physical damage..ect. So it may not work for all. But for me its worked and the error has NOT come back after 1 month!.

marisha

How you root your device? And i can't calibrate my galaxy tab 2 7.0, because the battery can't be charged 100%, any suggestion?

chorrylan

I have suffered with this intermittently for over a year. The problem in my case at least was related to the humidity; with low humidity it functioned happily; as the humidity increased it got correspondingly worse.
so.. what's the humidity been like for that month of perfect operation?

I use past-tense here because I took the phone with me to Queensland, Australia a bit over a month ago with super humidity and non-stop rain for days: the problem reappeared on cue and escalated to the point where it burnt out the LCD.

To top it off I just got a response back from Samsung warranty service saying they can't/won't repair the phone "due to damage caused to the LCD" wtf????

If I hadn't already bought an S3 to use whilst waiting for the warranty response this would have been the last Samsung device I would ever buy; this problem is common enough they should be issuing a recall to fix them rather than just relying on the weather.

j4g3d

Its been now over 2 months and the problem has NOT come back.

When i first updated as per my steps above the weather was about 16c, but before i followed the steps above i got this error message constantly. The weather now is between 18c and 29c and fairly humid.

In my case it certainly is not a humidity problem.

Like i say you may have a different cause but throwing up the same problem.

(Samsung Galaxy 2 - rooted)

Greeting folks,

I have the issue of receiving the "voltage too high - disconnect from charger" after it is removed from charger - just like many of the other posters.

In my case, I know what caused the issue but do not know the correct or most methodical way to perform a fix. A miki of vodka on my coffee table had fallen over and spilled unbeknownst to myself, and when discovered my bottom of phone was wet lying in the thin "puddle" - after perhaps 20-30 minutes. It was the wetness / Mr voddy that caused the phone to malfunction.

I left the phone, face up and with battery removed and cover off over night (as one is directed to do with a laptop (but which would also include removing the hard drive and all other removable devices) and when I restarted the phone 10 hours later, it exhibited the "voltage too high" with a flashing battery icon and notifying beeps.

The phone appears to work fine well plugged into the charger.

So, knowing that it was definitely a "moisture incident" that led to this, I am thinking that I need to either clean something OR maybe do something with the battery as suggested by our friend who discharged his battery to 17% twice and then (and I need help on this part) "reset" or "reprogrammed" the battery?

Many thanks for any help

The usb charge point is contaminated causing a short circuit it aint nothing to do with softwareor rom
Upgrades .its a physical electrical short circuit.i have had mine under a high powered optical lense and the units all greeny blue coloured showing sume kind of metalorgic breakdown.bad design dirt n moisture get in due to no dust cover chemical reaction takes place on mini usb port and thats tour problem new usb port required.

j4g3d

In your case i would personally clean all contacts and replace the charging board, i dont know where you are from but in GBP it is about 4.99. Easy and cheap fix. While you have the phone open check the board to see if it has corrosion from the liquid damage on the board, if so clean/brush away.

vickygautam

I used to get this alert once in a while when I disconnected the charging plug from my S2. And today it was as if it was a permanent behavior of the phone. Thanks to all you guys on AndroidForums! I fixed this with out spending a penny. It was so simple.

I cleaned the charging port with a small needle. It did have dusts and other stuffs on it. I also bent the pin to bring it to the center position with little pressure. The pin had bent to the lower side a bit. And I did all this with my phone switched on with blinking battery icon and at one time the blinking icon gave up. It was all stable and I switched off the phone to check the weird 'no switch off' issue. The phone did not switch on by itself. I guess I may have found the solution to this problem on my phone.

It's no way related to ICS or any other software. It's a hardware issue!!!

gltbiter

I too have this problem. My phone is 6 weeks old. Has never been near water. It started doing this last week. (Charge paused voltage too high). I ignored it till the battery went dead and wouldn't even turn on. I took it to my sprint store. they said it was a bad usb port and got me a new "refurbished" phone. I took it home and the phone died that night. (on the charger). I looked at it and it had the charge paused voltage too high message on this "new" phone. I can only use it plugged in. I took it back to sprint and they said they were stumped. the tech that could fix it will be in Mon. ??? I have used 4 different usb cables that work on 4 others phones. My Samsung usb kit works on the other 4 phones???? Sprint acted like they had never heard of this prob. That kind of bugs me when I come here and see it is very common.

Dear All

I had this problem for last 2 weeks, I updated the firmware from [ PDA:LP7 / PHONE:LPA / CSC:LP9 (INU)]
to [PDA:LPW / PHONE:LPB / CSC:LPC (INU)] on my S2 using kies.
It works fine now :-)

guys I have the same problem, I did all the things, even replaced 2 times usb flex cable, but still have voltage problem, slow charging (it takes up to 10 hours to fully recharge, and drains fast), and it powers up automatically if I restart, shutdown, or reinsert battery on the phone. Also I replaced battery & wall charger, but still the problem occurs. The technician cannot find other defects after replacing two times new usb flex cable. Now I got the phone back and still with problems. Any idea what could be the problem? Thank you.

btw; im using cyanogenmod 10 nightly (jelly bean), i'm 100% sure that its not software issue, tried everything like flashing custom roms (went from original ICS), still it doesn't charge fast and shows over-voltage. Its ******* annoying.

I keep seeing this posted as a possible solution. *Which* pin?? Does anyone have a clear picture or diagram of which pin to move, and some ideas on how to move it? It is so tiny in there I can't figure out what people are doing.

Thanks

PeepoUK

I think what they mean by "pin" is the part that goes into the centre hole of the charger connector (I'd describe it more like a blade).
I had this issue with my phone starting last night. As an earlier post said, it's highly likely just a short circuit.
I cleaned my charging port with a pin and all seems good again.
I have the same ICS ROM installed since the day after it was officially released by Samsung, so I would think software issues are not the problem here.
I hope you all get things sorted.

Pixl

I hope this gets seen...

The solution I had that worked the best for me was this one: https://code.google.com/p/android/issues/detail?id=32633#c21

In the UK 'rubbing alcohol is called surgical spirit.

My issue happened this morning. I pulled the Samsung charger out and got the error popup. Despite rebooting and taking the battery out, it continued. It even flashed up the charging image when turned off.

**NOTE** this may seem obvious to some, but for the love of god take your battery out when doing this and don't put it back in till you're confident the port is dry.

I used a toothbrush with a tiny bit of rubbing alcohol on (after dabbing it on a napkin to remove most of it from the brush) and gently scrubed at the port. The rubbing alcohol doesn't take long to evaporate and you can blow on it slightly to speed up the process.

If you don't feel confident with doing any of this, I'd recommend sending it in for a new one.

I'm going to drain the battery right down today and leave it overnight. I'll let you know if the problem returns, but for now, it's fixed.

HELLO FRIENDS,

All the below mentioned tricks like cleaning the port, falshing software, rooting. will not help at all.

The real problem is that the charging circuit got "SHORT CIRCUIT", That means if u still keep on running the Phone i might probably go "DEAD". The reason behind it is "Exposure of the equipment to moisture" especially the "CHARGING PORT".

Solution :

1) If u want to continue wid the phone go to the Samsung Aurthorised Service Centre and get the Charging Port or in worst case get Charging PCB (PCB is the Printed Circuit Board over which the entire charging cuircuit including the charging port, power IC and other required items are fixed) change as applicable to your particular case. In Delhi (India) it will cost RS850(CHARGING PORT) to RS4000(ENTIRE PCB EXPECTED COST) .

2)If u don't want to continue... Sell IT. If possible with the problem..

"I feel samsung mobiles are full of troubles and poor quality. There are so many models of a single phone and the samsung regularly launces new models into the market very frequently and that also without proper testing and quality checks & that is the reason because of which we all are facing so much trouble with particulary samsung phones (from samsung low range phones to high range phones).

Jus to support wat i said above: When I went to samsung mobile service center at Ghaziabad at 11:00AM my wating number was 150. can u imagine tat, the store opened at 9:30 AM. The guard told me there was a Que even before the store could open. !! GOD SAVE SAMSUNG USERS!!

Hi All. I have had the same problem for just 2 days but after reading all the threads I believe I have it fixed. Look into the usb port on the phone with a magnifying glass - it is not disimilar to your belly button! Full of fluff etc from your pocket/purse or wherever you keep your phone. Use a long THIN needle to carefully scrape the crud out. Then a good blast with a hairdryer and voila!

gizmo_user

I think before any galaxy S2 user attempts to root or even carry out the factory reset, it might be better to carry out a process of elimination first.

When this message came up on my phone, the first thing i did was power off the phone for at least 1hr. When i switched on the phone, i didn’t get this message again and there was no problem charging the phone, either by the charger or the usb port!

I was surprised to receive this error message, but i suppose i do use the phone to watch youtube vids on most nights, for two solid hours straight, so i guess it was just a matter of time before i received such a message.

[SOLVED]

This is my first post ever but I cleaned the charging port and bent the pin back to the strong side now it is fine thanks

Ok so here I am on this thread after reading about the "Charging paused voltage too high" problem on the internet for HOURS.
I use a custom Gingerbread ROM on my S2 and my phone always worked great. Last week I accidentally splattered a soft drink on my desk and a little bit got on my phone. I wiped it off and later that day started having strange battery problems. Oh, and I can't connect to a computer anymore to transfer data.
I wasn't positive that it was caused by the soft drink spillage so I decided to flash a new ROM and see if that would fix it. I loaded a custom ICS ROM and immediately started getting the "Charging paused voltage too high" warning. The phone seems to charge to 100% but when I disconnect the charger it still thinks it is charging and will stay at 100% for a couple hours, then plummet to below 50% and die out fast, just like before when I had GB.
All this plus reading internet posts leads me to believe it is a bad micro USB connection. I took it to the Sprint store and asked if they had any tools or methods to clean/fix my USB port. They looked at it under a microscope and said the pins are badly corroded and the problem will only get worse and my only option is to upgrade to a new phone since I don't have insurance. They didn't even suggest that the USB connector could be cleaned out. Thanks Sprint.
So now I am going to try 2 things.
1. Try cleaning out the USB port with alcohol and a toothbrush. I think this will only be a temporary fix though or might not fix it at all.
2. I ordered a replacement USB connector on Ebay. It was 2 connectors for $7. Since I'm an electronics engineer I have access to precision smt soldering tools. I don't know but I'm guessing a regular home hobby soldering iron will not be suitable for the tiny legs on the USB connector.
I also found a service on Ebay to replace the USB connector for $40. So that's another route to go if you don't want to take the phone apart and solder in it.

I'll post later when I have longer term results.

Update:
I have access to a microscope at work. Turned off the phone and removed the battery. I looked at the USB connector and saw a lot of gunk in there. I used a tool similar to a dental pick to scrape a layer of stuff off the pins and gunk that was around the inside of the connector. I spent about 20 minutes painstakingly doing this. The connector is so tiny there is NO WAY to do this without a microscope!
And then I took a little piece of lint-free tissue wetted with alcohol wrapped around a toothpick and scrubbed the pins some more.

All problems are gone, the "Charging paused" warning message is not popping up, and the phone is working perfectly. The battery is not draining fast, and I can connect to a computer and transfer data again.

SOLVED.

jmm92108

On Ebay I found some silicon micro USB covers that plug into the port when you're not using it. A 10 pack is $7 I bought them and I am going to use them from now on.
