Hello,
my GSII does not take any voltage from any source (USB port or the charger) therefore can not charge it.
I have already bought a genuine replacement battery from my Samsung and already bought a USB board (thought it was the plug on the GSII) and made the replacement. When the battery came, it still had about 50%, the phone booted up just fine, never was able to charge it, after that i always get the temperature icon, even the temperature is not very high. The same battery also did not charge on a GSII friends phone.
This is a very strange symptom, any help or ideas would came in hand.
Thanks,
chapas

Could be a hardware issue.
If you are still on warranty, go to the store/service center and ask for a warranty replacement of the battery and/or the phone.
Good luck !

Thanks for the answer, i'm out of luck, it was an eBay buy.
Just to add more info, i have a mains charger 5V, 1A. I've used it for months, i know that the GSII takes 0.7A but it is capped (read this on this forum), so i used this one for convenience.
I don't know if it has something to do with this.

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

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:
youtube.com/watch?v=evDCM84xQCA
Heres the video of how to replace the charger port circuit:
youtube.com/watch?v=aChzv3IzxsU
(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.

Hi all,
I've searched and found no related answers to the problem I'm currently facing with my Streak.
A few days back my Streak suddenly couldn't charge thus I brought it down to a reliable handphone repair shop and i was quoted $90 (USD70) for a charging port replacement. I agreed and the technician proceeded with the repairs. After changing a new charging port, the problem is still there which is unable to charge. Technician then use his charger , battery and cable instead of mine but still to no avail. I was told to leave my Streak there to let them find out what's the main problem.
I'm now being informed that it would be more expensive if its the charging insulator or etc if it is. Current estimated repair charges would be $200 (USD156).
So what I would like to ask here is I believe the main problem is not with my battery , battery port and connector right? So if I were to just purchase a cradle + desktop battery charger and charge my battery through the cradle it would still work as per normal? It would also cost way cheaper too.
PS: My last step was using Whatsapp and then I proceeded to charge it and went to bed. The next day i woke up, my Streak was not charged at all.
Hello. I just bought a s2 i777 unlocked from eBay and i have been having charging issues:
when i unboxed the phone there was no battery juice available and would not turn on. I connected the phone to the default charger(ETAOU10EBE) that came with it and let it charge for 30 minutes and powered it up and then let it charge. i was not home when it was charging...so when i got back 3 hours later it had stopped charging at 74%.
I also noticed it detected the AC charger as USB PLUGGED. I used my nexus 7 adapter and after more than 5 hours it reached 100%. the next day i rooted the phone by flashing siyah kernel and flashed shostock3 4.0( it was on stock 4.0.3 before flash). here i noticed that with any adapter or cable i use the phone takes a lot of time to charge and does not get past 70%.
The phone showed it was charging but actually it was discharging. i powered off the phone to charge it but after sometime when i turned it on to see if it charged the battery the battery has lost all its charge in less than 15 minutes while the phone being off. I searched about this problem on the internet and some people are saying it might be a faulty battery or DAMAGED USB FLEX CABLE. OTG is not working also. i can use my usbdrive on my nexus 7 correctly but it does not detect on the s2. I am thinking the problem is with the USB FLEX itself.
OTG worked before i flased shostock3....
i also reflashed a rooted stock 4.0.3..but that did not solve any problem..so i flashed shostock again. i even flashed pure stock i777 jb 4.1.2...it booted the first time but as soon as i plugged a usb cable to pc or ac it turned off and kept on showing flashing charging battery...so flashed siyah kernel again via ODIN and restored a shostock nandroid backup. And now the phone do not get charged at all and OTG also does not detect,
Any suggestion is greatly appreciated.
i would gladly ship it back to the ebay seller for another one but shipping is high.
UPDATE: The problem was solved by replacing a USB FLEX CABLE...

Well yes, but if you can do that, it may be the most inexpensive way. One other possibility is that you have a bad USB port in the phone. You can replace that yourself, but you will probably pay as much for the replacement part, and then there is no guarantee it will correct the problem. I have seen several people post that they tried to replace the USB port but that it was not successful. Sending it to a reputable repair shop is also probably not practical or cost effective. So I say, get a working phone from the seller if you can.

creepy's probably right (a usual occurrence), but it could also be as simple as a bad battery. Buying things like this second hand can sometimes give you trouble like you're having, because you don't know what's really OEM or some shoddy off-brand. Another option for you would be to get a cheap battery that's been confirmed to work perfectly on the i777.
Several of us are using this $5 battery from Ebay; it isn't 22000 mah like it promotes (it's more in line with the 1650 that shipped with the phone), but I'm using it right now and have never had any issues. If you want to read further about those of us who've used it, read this thread starting from here.

The seller described the phone as new....it looked new to me when it arrived but it had screen protector perfectly aligned on it...i had the charging issue since day 1. I thought that the battery was new and needed to be broken in...hence the long charging time. The seller refunded me the $9.98 i asked for the defected AC charger supplied(it showed up as usb plugged in any device).
I already contacted the seller several times and after i got his/her approval i left the device at a repair shop for verification of the charging issue....will see how it turns out....i cant buy another battery as it takes more than 30 days for items to arrive here in mauritius...i asked a friend to lend me his s2 battery... Still no sign of him...lol
The local repair shop is taking around $35 to change the usb flex and other short-circuited parts....did you guys had any problem with your usb flex???
And can you plz guide me here : what is emmc superbrick bug?? the 4.0.3 stock rooted rom i flashed had this bug in it...the OP warned about it...could this bug cause this hardware problem i am facing?

I had a problem with the usb flex, I bought two of them on amazon or ebay (I can't remember), did the replace my self and my phone is back on business
4.0.3 has the brick bug, don't perform a factory reset if you're on stock kernel.
I don't believe that bug is causing the issues

Hello Everybody
My phone was working fine until last night when the battery completely drained while i was playing a game and it turned of. After that i plugged it in and went to sleep. i woke up this morning and tried to turn it on and nothing happened. I took the battery out put it back in and it started charging. i left it there for 20 minutes and when i came back the phone is completely dead. no response. won't charge, wont turn on, wont vibrate. nothing
so if you could help me out with the problem that would be great. thank you.
The battery may have shorted itself. You can purchase a new one for ~$10 on Amazon.

Thanks for your help. I just got done testing my battery in a friends s4. Its not the battery. His battery doesn't turn on my phone and my battery is fine in his phone. Its my phone that has a problem. Any other suggestions you might have will be really helpful. Once again thanks.
Well, if a charged battery isn't making it turn on at all, then the logic board is probably malfunctioning/hard-bricked. The only solution to that is to replace the logic board. Your best option, if you are in warranty, is to contact customer support and have them send you a warranty replacement. If not, the best option is to purchase an S4 with a broken screen and swap out the logic boards (better be comfortable prying open your device).
Thanks for the help.

Hi everyone, I got a poco f1 from a friend. He used it quite normally. The cellphone was off for about a month - it didn't work. After a month I tried to start it however unsuccessfully, poco f1 is dead, I tried to charge it but it can't. What could be a malfunction? Help if you know and thank you very much
First, try using a different charging cable and brick. If it doesn't charge, Check if it can be read using a computer or laptop. If it still doesn't work, then the issue may be the charging port. If that's the case, if you are still covered by warranty, then go to xiaomi store. If not covered, go to a proper technician.
Btw if the device can be read on a computer, then it may just be a boot issue. Just flash again.
Does the white charging led light up when it's on charge?
If not, have you tried leaving it on charge for an extended period?
I've had difficulties with phones in the past after batteries have fullly discharged - eg the Moto G5 had some battery protection "feature" that stopped it starting up if it thought the battery was fully discharged - it was a bit over sensitive so would sometimes assume the phone was fully discharged when it wasn't
Try leaving it on charge for 24 hours or so then holding down the power button for for at least 20 seconds with it still on charge
If you have no luck and the warranty is out, get to a repair shop (or disconnect and reconnect the battery if you're confident to open it up - for a while I was getting sporadic shutdowns with my F1, following which it wouldn't take any charge, the battery light staying off when plugged in. This was all fixed by tightening the screws securing the black motherboard plate, the cover which retains all the connectors - not sure why but it seemed something, I suspect the antenna connection, had come loose. Since doing this about 5 months ago I've had no further shutdowns and my phone is usable again, having been completely unreliable before)
One trick that worked on some old Nokia phones was to charge it plugged to a computer instead of plugged to a charger - but as said elsewhere, if the battery is completely dead, YMMV.
Also, try to press and hold the power button and while doing that, plug the phone to the charger and then release the power button.

I guess your battery is dead
I have same issue, however I think my one is a motherboard charging IC issue. Does anyone know a way I can get it cheap from India, as I’m in the UK. India have it for around 9999 rupees which is about £10(+international shipping). I’ve ordered a charging port replacement from AliExpress to see if that solves the problem. However I don’t think that will work. No idea how my motherboard got damaged in the first place. I replaced a cracked screen myself and the phone was working fine for a few weeks, then it stopped charging all of a sudden. My PC also detects it/can access files doesn’t charge it. A new battery powered powered on the phone but again didn’t charge. Tried different adapters and cables too. Any experts out there know whether this is a motherboard issue or just a charging port issue?
If the phone is OFF for a month, then it is probable that the battery has gone down to a point that the BMS has shut it down. The BMS won't allow you to charge the battery because, in its own assessment, the battery is dead. Best way to test this case is to have another Pocophone with a good battery (or just a new battery altogether), detach the cable from that and test on yours. This may or may not work but this is one of the easiest to test and a new battery is easy to acquire.

Before you do that, just try leaving it in charge for 24hrs as suggested above, though it does look rather as if the OP has nicked off so won't be using any of these sage words!
