[Q] Battery charging issue - Galaxy S II Q&A, Help & Troubleshooting

I know there are hundreds of threads like this, but I found myself with a strange problem...
My S2 will connect to USB perfectly, will be able to move data, big files like ROMs, even flashed a CF root through Odin, everything ok...
Well, it will not charge, when the USB or wall charger are connected, it will display the power icon, but will not be animated nor charging, keeps draining battery even if connected.
When it hit 5%, it kept playing the low battery/charger connected sounds, like some kind of failed USB connection, which I not believe to be the case...
Already cleaned with isopropyl alcohol the battery , battery and charging port (without alcohol).
Waiting to try it...
Any sugestions? battery seems to charge in other phones

Try another battery and/or replace USB board/port. Regardless of whether you can move data to/from the phone via USB, it very much sounds like the board/port needs replacing. Quick/cheap/easy to do yourself, has been covered here a lot this year - search for threads where KeithRoss39 & TheUnderling have posted on this issue to get the info you need.

Already switched the usb board (as today), the battery is charging now, but only with the phone turned off, it will stay as before, not charging the battery, already installed a different ROM (using Disaster v10)
I dont think thats the battery... will try to put my hands in another battery and see.
In the meantime, is there anything else I should be trying?

[Q] How to fix battery over voltage?

My battery's been on the fritz for the last days now. Whenever I turn my GS2 off, it will shows tha battery charging screen, then flash to another icon that shows a battery, exclamation mark in a yellow triangle, and a thermometer. It had to plug the charger in to get it to turn on, even though battery was at 100%.
So, I decided to download Battery Doctor to check my batter stats, and it says 'Health: Over Voltage'.
Does anyone know how to fix this? Help would be much appreciated.
I have exactly the same problem. I have not found a sollution, am thinking of calling samsung and explaining the situation. I will post here if i have a sollution.
What OS version are you running?
What Kernel version are you running?
What carrier (if any) did you purchase the phone through?
I'm on 2.3.3 (KE7), using Chainfire's kernel. Phone is carrier unlocked, unbranded from clove.co.uk.
Btw, I think I may have fixed it. I discharged the battery and used a charger with a lower voltage output to get it fully charged. (Charger I used if from my spare phone, a Samsung Champ). It now says that my battery health is good.
Now, the problem is that my phone won't stay powered off when I turn it off. It will stay off for 1-2 secs and power back on. Even if I remove the battery, the phone will power on after i place the battery back without me touching the power button.

I have the exact problem. Is the battery health still good? I would like to fix this by myself and not send it in and be without my GS2 for that time.
You should try this:
1. be sure, that your battery is full (charging over night)
1. run the app battery calibrator
2. unplug charger
3. drain battery all the way down till it shuts off
In this way your phone can remember what is 100 % and what is 0%
My sgs2 shows 4,194 V at 100 %
I think your stats (look into battery calibrator) said that 100% are for example 3,8 V
PS: You need root permissions
---------- Post added at 04:55 PM ---------- Previous post was at 04:49 PM ----------
Please post us your current voltage.
I have this exact problem. Battery Calibration is pointless, we all know that.
Did anyone ever find out if this is fixable, or do I have to contact Samsung for a replacement?
It's quite annoying that I can't turn off my phone, it just powers on after about 2 seconds. In addition, I never know how much juice I have left in the battery as the reported capacity can jump from 90% down to 6% in an instant. After a reboot it might go up to 12% but I can still use the phone for hours without it shutting down...
Yeah
I've been having the same problems as all above...
Galaxy S2 on Sensation rom, but its not the rom, i flashed to another and the problem still remains...
It all started with phantom charging...(charging when the charger is not even plugged in and constantly making the "charger connected" sound)
I got the phantom charging fixed by cleaning the charger port with a cotton bud and some cleaning alcohol...But now i have overvoltage...
And just like the others, it'll stay on for example 100% and if you reboot its suddenly on under 10% and slowly works its way up to 20 or 30% without even being charged.
I'm assuming the battery got messed up during phantom charging, in tthis case calibration doesnt help, nor does flashing another rom. Flashing another rom leaves the phone stuck in MTP mode therefore unable to use it as a flash drive.
A vid on youtube reccomends replacing the part of the circuit board to which the charger port is attached and as well as the battery at the same time as the battery always gets messed up with the overvoltage issue....
When i have overvoltage i cannot charge even when its under 10%, unless i leave the charger in and reboot the phone it will then charge once it comes back on and it even says GOOD HEALTH until i unplug the charger.
I'd really like a definite solution to the overvoltage issue...
Bump!
Did anyone find an answer to this problem? Mine has started exhibiting the same behaviour. I haven't been able to search out any solutions...
Cheers, PF.
EDIT: Whoops! Just realised I'd better change that signature to SGS2-able. lol
I am also seeing the same issue for the past 3-4 days, I have switched off the phone and took out the battery, planning to visit samsung support center.
I hard rebooted the phone(which reset it to factory) that did'nt help.
will update once I get more info/help from Samsung support.
Vikas
i had the same problem as you guys and i fixed it by cleaning the contacts on the phone where you connect the charger. use some cotton buds and a needle and some alcohol and clean all the contacts at the bottom of the phone (usb cable slot).
make sure phone is turned off tho whilst doing it. that fixed my over voltage issue.
Hi Guys,
I went to Samsung Mobile Support Center today, they told me that USB mini port has turned slightly green, which means that it has in contact with Water
this will not be covered under warranty and might need to be replaced with charges
Tomorrow they will tell me the exact cost.
I still believe, its not an issue of Power port but with the battery port.
will update if I am able to get it solved.
It's a problem with your usb charging port. The only way to truly fix it is to have the charging port plus circuit board replaced. Happened to me a week back and I tried virtually everything- stock roms, removed root, replaced batteries etc. None of that worked. Some posts said it was a port problem. Went to a tech guy I knew and he confirmed the issue when he disconnected the port. It was relatively cheap for me to fix but some people have climed that samsung charges a large amount to fix it. You're better off trying to get it fixed on your own. If you're on warranty, try and claim it.
Also alot of people are having this issue- yours is about the 5th topic I've seen about this problem this week
Hi Guys,
My problem is solved. Samsung support replaced charging port and the chip it was in(total cost 650/- INR, about 13$)
now phone is working as before.
i have the same problem on my gs2, so can i fixed this problem by cleaning the mini usb port?

Cleaning the usb port will/might help with phantom charging , but not overvoltage.....
For Overvoltage you may need to replace the whole USB port part of the circuit board (easily obtainable on EBAY) and you have to replace the battery at the same time as well cause the battery (also easily obtainable off ebay) gets damaged with the overvoltage problem.
I have ordered both about a week ago, awaiting 3 weeks for it to arrive to my country.
Good luck with that...
Theres videos on youtube of how to do the repair for overvoltage yourself...
Will report back here if circuit replacement worked for me...

When you open your s2 for the first time it is tough, but after that it is very easy...
I have already opened mine before to replace the loudspeaker, so it is now easy for me.
Heres the video of how to open your s2:

(or do a YOUTUBE search for "Galaxy S2 USB Flex Cable Replacement ")
This video also has comments that explain the cause of this problem...!!!!!!!!!!
That is the part you need to replace, the USB FLEX CABLE...(its the ribbon cable and the board, but they call it a flex cable)
Hope they help you.

[Q] Interesting charging problems on my 4.0

Hey guys, it's been awhile since I asked a question, but here I am, lol.
In a nutshell, I'm pretty sure something in my device (hardware) is fried, but I thought I'd see if anyone knows better.
The problem is my device seems to be sending power out of the usb port, and doesn't connect to the pc or recognize it is charging correctly.
This also applies to download mode (windows says device has malfunctioned) and when powered off (there is no battery that shows up when plugged in). In order to power back on after turning it off, I have to remove the battery, then reinsert it while holding down the power. I can't think of much that could have caused this, other than I was visiting places with high humidity levels. One unusual thing that happened before this started was my device rebooted into safe mode when playing bad piggies. That was really weird since I have tried booting into safe mode before, but thought samsung must have disabled it for some reason. I have already tried wiping data and flashing a new kernel/rom. Obviously I can't re-partition since I can't connect to my computer in download mode. What do you guys think? I think it is time for a new device.
EDIT: I should mention that it started behaving normally yesterday for about 5 minutes, but then it went back to this.

I'm 99.9% sure that under normal conditions that an Android device should never power the USB port. Source of speculation. If it is indeed powering the USB, then you've either got a really wonky firmware installed, or some sort of hardware issue. I'd try to make sure that it's sending power out before going further (especially if you can't charge it, the battery will be dead soon). After this test, I'd keep the battery out for a while, just to be sure it's not going to short anything.
One thing I've noticed in my tinkering is that taking a device apart, then putting it back together again can mysteriously fix problems (although 75% of the time the fix is temporary). If you suspect water damage, opening it up and letting it air out might help. I want to say there are certain cleaners that are great for cleaning up any water spots that might be shorting things out, but I've never had to try myself.
That's all I can think of right off. Good luck.

Yeah, I'm working on taking it apart right now. With my limited experience on electronics, I would be willing to bet it's a capacitor that's gone bad somewhere. That wouldn't be a problem on a desktop since I could just solder a new one in, but I don't think I have the skill to do something in such a small scale, not to mention I don't think you can even buy them that small.
The same thing happened to me, and I had to send it in for repair. Luckily, I was still in warranty. Also, are you sure it's not the charger cord?

I've tried multiple cables, and I'm unfortunately out of warranty.
Upon disassembling and cleaning with rubbing alcohol, it seemed to be working properly, with the exception of computer connection. However, I plugged it into a DC car charger (leaving the charger itself unplugged from an outlet), and the light came on again (which is what I was talking about when I said it was sending power out), and now it is acting weird again. I guess I'll take it apart and clean it again...

See! Told you taking it apart and putting it back together again works... temporarily. :silly:
You're right, that does sound like power going out. Which would be super cool for powering, say, a micro USB laser pointer, but it's not so great when it should be charging. Can you double check with another device that the charger doesn't light up normally? I know my wife's laptop charger has a LED that stays on for a long time after it's been unplugged from the wall, sipping off of power left in the charger. It could be something similar with your charger.
Just a though... if power is only suppose to go into the device, then wouldn't it be reasonable to assume to that there would be a diode forcing power to only go one way? Or does it need to cycle power back to the charger? IDK, but it might be worth looking to see if something looks missing.
I read somewhere that if the battery voltage gets too low i.e. battery is totally flat, a current will flow from the device to the charger so this may be what's going on here. I didn't really understand the post as I was just whizzing through the thread, but i think the solution was to charge the device for many hours until the battery voltage was high enough for normal charging to occur. I'll try and locate the post, but it might take a while

@iJimaniac if all of these suggestions dont work, there is the possibility to just buy another battery and a battery charger and keep switching out the batteries when they die
Maybe @henk5066 would know something about this?
From what it sounds like, your power circuit is fried and is not directing power correctly this means that you're probably going to have to replace the mainboard. however don't worry. you can get one from a player with a broken screen on ebay for about 10 $. I can p.m. you some links to products on eBay with main board working and not screen and I can post a video on YouTube that shows you how to replace the board. it's actually rather quite easy. I don't get why most people don't do that and instead buy a new one. let me know if that helps

Wow, I didn't realize a broken player is so cheap. I'll look into it, and instructions won't be needed; I've already fully dissasembled my device many times in the past, just for kicks.
Edit: could you send me those links? I'm having a hard time finding very many under $25, which is still a good price I suppose.
the broken player it's self is cheap (0.99$ if your lowest bidder and win) it is shipping that makes up for most of the cost. Just make sure you get one that says powers on, that is the main indicator that the main board is still good.
EDIT: I just looked on ebay, aparantly the person i bought my new board is out of the 4.0 player. and it looks like there is however one with a 9.99$ bid. you could raise it and get the player but that is the cheapest you will get. i will pm you a link to it.
I had the same problem
I had the same problem, what i did was, instead of charging it with the original charger, i charged it with my nexus 10 charger in download mode all through the night, and the next day it would have about 80 percent charge and it was in the system, but it drained quick when i would unplugged it, so i repeat the same procedure over several days until get to 100% and scince then i have had no problems with my SGP, hopefully i helped you

On the subject of odd charging behavieor, has anyone noticed that when plugged in running cyanogenmod overclocked to 1200mhz, the micro usb port area on the player gets rather hot?

Battery weird - seems to be phone but no obvious hardware issue

I have a galaxy s2 and bought a new battery recently (samsung one) thinking it would solve an issue which I thought was my battery.
Its very hard to describe but will do my best (have checked other threads but nothing quite like this..):
The battery will always say charging when plugged in but will sometimes increase in charge and other times not. I can charge overnight sometimes and it will say charging 7% and in the morning be completely dead and will not even show the charging animation (I have fixed by using my girlfreinds phone to charge it a bit and then it will be fine for a bit).
I thought might be charger - but my girlfreinds s2 charges fine on it - her phone works fine on both batteries and charges both fine.
Seems to be something to do with my hardware and I thought it may be the charging port - but not sure as it does still say charging without having to wiggle or anything like that so that suggests not the port.
The other thing that suggests something other than the port is I have had a battery in my girlfriends phone with it on, then plug it in and it said charging 37%, take it out and put in my phone with it plugged in and turn the phone on and it will say charging 4%...
Does anyone have any ideas as to this? Any things to try?
Thanks heaps in advance!
Do a clean install of stock & test for a day or two, if you're already running stock skip straight to replacing the USB board/port. Given you've already replaced your battery, this is likely to be the cause of the issue. Search for KeithRoss39's guide in the General section; it's quick/easy/cheap (<AUD$10 for me) to do.

[Q] Broken S2 - turns off random moments after booting up

Hello
Yesterday my phone randomly shutdown. After that I werent able to turn it on even after wiping everything and reinstalling the rom. When I came back home i flashed the official firmware with odin and it didn't work as well. Then I managed to turn it on successfully while it was plugged to a charger. I managed to observe that when I normally turn it on it starts only plugged to a charger and turns off after cuople of seconds. This doesn't happen when I enter recovery mode or download mode - I can boot successfully up my device to these modes and it doesn't turn off without need to be plugged. What do you think happened to the device? Can it be fixed on the software level? If not how much do you think it would cost to fix this if it is a hardware issue?
up
Are you sure your battery is healthy?
Remove your battery and see if it has got any exapndings or swelling? Cause I had the same issue except after losing half of it charge it would suddenly turn my phone off like I'm removing my phone when it's still on!
The battery looks 100% normal. I'll check tomorrow with my friend's battery. But in recovery mode phone doesn't have any problems.
Any other ideas? Can it be anyhow software related? If so is there any option to fix this? What should i try?
Replace USB board/port; quick/cheap easy to do yourself. KeithRoss39 has a guide in General (not stickied, search for 'replace USB charger board' or similar) which has all the info you need to get it done.

But the phone does charge well. And it works on battery in recovery. It turn on normally only plugged into power source and the shutdown randomly. How could changing usb port could fix that issue?
Because USB board problems almost always (at least that's been the experience on here) manifest themselves by showing a few faults & working OK otherwise, rather than dying completely - you might be able to charge OK, you might not be able to transfer data all the time; you might be able to transfer data OK, you might get constant shutdowns which you can't explain by changing firmware & trying a new battery.
Everything you've said in this thread so far points to the USB board, and as this is an easy & cheap fix, if it was my phone, that's what I'd be replacing to try and fix it. Put it this way, given how cheap it is (around US$10-$15), if this doesn't fix it, then you'll know there's probably something more major hardware-wise going on. I wouldn't be taking it to a mobile repair shop to have this done though, as obviously they'll probably charge you a crapload in labour to replace a $10 part. Save that for if changing the board doesn't work.
Thanks for your effort. The problem is I don't think i can do it myself. I don't want to spend much money on this phone cause it is quite old. That is why I kind of don't what to do now

[Q] Question regarding Slimkat 4.4.2 and battery

Hello and thanks for taking the time to read this, let me explain a bit first about what happened:
A week ago, i changed my Samsung Galaxy SII GT-I9100 from Cyanogenmod 4.2.2 to Slimkat 4.4.2, and everything was perfect the first day, but then i stumbled upon something that didnt happen before, suddenly my battery stopped charging, it would show its connected, but would go up in %, after trying to connect and disconnect for over an hour i got it to charge a phew % up to 15% and got stuck, so i tried to create a new battery stats with terminal, so i did and it charged for a bit then stopped, so ive been using the phone like this for a week now, i took it to a repair center and they told me it was the battery, since they plugged in a battery of them and started charging flawlessly, so i bought a new battery, but now it kind of charges for a while but gets constantly stuck at a random %, so i unplug and plug back and charges again. So the question here is:
a) Is this caused by a bad rom flash and not wiping anything? i wiped a memory card, but dont remember if it was external or internal, my pictures and everything were still there.
b) Is my charging port busted? wich seems weird because this didnt happen before.
Thanks in advance!
Yep might be the USB board/port (I presume you bought an original Samsung battery ?)
Clean install of stock, test for a few days. If it's still happening, replace the USB board/port. Search for KeithRoss39's guide in General (search for 'replace USB charger board'), has all the info you need; quick & easy to do yourself will cost you ~US$15.
Edit - Actually, now that I think about it...Don't flash stock with Odin, just in case the board is on the fritz. Get one of the CWM flashable stock roms from Wanam's thread in Development & flash/test that for a bit (still do a wipe though). If the board is on the fritz & you try a flash, there's a very slim chance you might brick it (Keith has a theory some of the bricks we see are people attempting flashes with dodgy USB boards).

Thanks for the reply man! i actually put the old battery inside and its working a bit better, never the less its still frisky to make it charge, sometimes it charges for a good chunk of battery then stops, but says its still charging, then i unplug, plug back again and keeps charging, if i were to replace the usb board/port, wich version should i get? my cellphone is the Samsung Galaxg SII GT-I9100, but ive been looking at some charging port replacements and they say something about REV 2.2 and stuff, so wich is the one i should get? This is the one im thinking of buying, is that one the correct one? THANKS FOR THE RESPONDE BTW!
