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...

thank you for you explain,i want to know is it difficult to replace the circuit board by myself?
hey guys, my gs2 also have the same problem, i fixed the problem after i cleaned the usb mini port, it will not show charging whatever i haven't plugged the charger and the problem of over voltage also fixed it YEAH!!!
sorry for my poor english

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.

Thanks, but the problem is solved by cleaning th usb min port, i no need to replace the flex cable anymore,.
For past few days, I'm facing this strange problem that the phone doesn't charge beyond a particular limit, and sometimes at all. When I plug in the charger, it displays 'Charging' but the battery level doesn't go up. I tried few things to understand where's the problem:
1.) I changed the charger and used the other ones (700mA, 500mA, USB charging with PC) and they worked well for a while, although slow charging, but afterwards the issue re-appeared and phone stopped charging even by them.
2.) I changed the battery, thinking it's a battery issue. The one that I got from a friend charged perfectly well with my own MMX charger for the first time, but now it's giving the same issue again and not charging beyond a particular level, say 40%, which will eventually come down and it won't charge at all.
I'm confused as what kind of problem it might be - hardware issue with the charging socket, charger/USB cable issue, or a firmware issue? Has anyone faced this problem till now wherein the their phone doesn't charge, even though it shows 'charging'? Please share what did you do to resolve it. I'm currently located at a remote place and cannot visit a service center.
how old is your device? if it's more than 9 months you might have to replace your battery. you could find it on ebay.
Hello all!
I recently purchased a used Droid Razr Maxx from a co-worker. The lcd screen was cracked so I replaced it. I took apart the phone completely and reassembled it with the new screen in place. The phone turns on just fine, the Motorola icon shows up and it gets to the charging battery icon with 5%, but after a few hours of letting it charge, it stays at 5% and wont turn on. Keep in mind, the phone has been charging for two hours from the time this post was made.
My question is, did I somehow damage the battery when operating internally? I can replace the battery if needed.
Another question. If I damaged the motherboard, would the phone turn on at all?
I am kind of wondering if there is a certain thing I needed to do before plugging it in.
To answer any questions that might be asked: The battery was completely dead when I did repair the screen. The charger is a wall usb charger, not plugged into my computer. I did place all the components inside the phone, to the best of my knowledge. I have had experiences when it comes to internal repair.
check for how long this 5% charge remain. it usually happen due to problematic battery guage

Morning now. The battery is still at 5%. The phone shuts off soon as the charger is not connected. Does not seem to hold a charge. Think I should buy a new one?

It could be a faulty charger.
Normally, If the battery is poor, it won't hold charge but it won't stick to a particular percentage. It will only discharge sooner. But given the fact you got the phone dead, it might as well be the battery.
Worst scenario, you damaged the charging port.
I'd begin with using a different charger, if that doesn't work, try another battery.

I have used other chargers and they all work for my other phones, just not this one. I am hoping it's a dead battery and not something to do with the motherboard. My friend wont let me dismantle his phone to see if it's the batter, lol.
Just the clarify, the phone doesn't boot up completely, only to the charging screen. The battery icon with 5% shown. When I unplug the phone from the charging screen, it just dies. Will not even boot up to the phone animation.
I purchased a battery replacement off of Ebay. It'll arrive in a few days. Let's hope this works!
Still could be the charger. Did you check voltage and amp specs? 850amps 5.1v
This phone can be picky. First razr I got had broken screen, repaired it and found myself in the same situation.
Connecting to a laptop would not charge it. Only stock charger. IPhone charger or chargers designed for iphones will not work.
Edit: When replacing battery, position is critical. If battery terminals are a little bit displaced it will not turn on.
Displacement can be minimal or imperceptible but will cause troubles. If possible don't place cover before checking that it turns on. (please avoid touching circuits or battery terminals or will get worse).

That was exactly the problem....
I got the new battery, but not 24 hours later, I was realigning the cables inside it (like the front facing and rear cameras, along with the WiFi antenna) I slightly moved the replaced battery and the cable to the battery to the motherboard tore itself. After a long face-palm moment, I got the old battery back in place and realigned it very carefully. It turns out it still works, but I am out a new battery.
Apart from the battery, I need to find out why the front speaker won't work. Either the speaker is damaged or something needs to be in place correctly, besides the cable. Also need to get some adhesive gel to bond the screen and case together.
Damn I really had forgotten about that speaker. The fact is it tends to break. It has very fine copper wire winding that can break when you remove it the wrong way.
Having no experience I pulled not knowing that speaker is glued to motherboard. At that time I didn't knew it and thought that little bar left was part of the motherboard.
Since you disassembled almost everything, that must be the reason it is failing. If it is not that, it is badly plugged but I really doubt it.
Alas Never fixed it, so i can't tell correct process to reassemble or disassemble that speaker. Instead I searched for apps that would activate loud speaker automatically during calls.
Would have been nice to fix it but I got the opportunity to acquire a RAZR maxx so never touched and sold instead.
Removing that glue might involve using a hot air gun. So that you don't damage motherboard removing by force. (But again too much heat could Fry motherboard)
Maybe someone could share it's experience?
About that screen, Remember to have read about a 3m adhesive spray in some thread.
Also some one just passed hot air that melted original glue but it would be better not to play with heat over a battery.

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!

yep mine also. i was playing genshin impact and suddenly it freeze and off. service center said it was dead motherboards.
I have a Redmi note 10 4g and it fell 2 weeks ago. After that it stopped charging, i could fiddle with it by plugging it in a few times though and it worked again for about a week. Mind you, nothing is broken as seen from the outside. Last week however it fully stopped charging. I could still completely use the remaining 80%. I fiddled alot and even cleaned the usb c port but nothing helped and eventually the battery go empty after using it. It does not detect the usb c at all. After that i ordered a phone repair tool kit from ebay for 11€. i opened the redmi note 10 4g from my sister (the phone has a completely cracked screen), took the usb c daughter board out of it and swapped it with the one in my phone. Despite this, my phone still doesnt charge. I could still see the empty battery logo when i long pressed the power button after the repair, so im fairly certain i didnt break anything on my phone.
So, is there any other thing despite the usb c daughter board that could be broken, causing the phone to not detect any usb c despite working otherwise?
Btw, I also did see the daughter board for 1 € avaivable on a website but i didnt want to wait for that, and the one from the other phone should be working
The wrong replacement part.
The battery has failed.
Loose or broken connector or ribbon cable.
Mobo failure.

Yay! You're welcome.
Anytime you're inside and the battery is a year or older it's a good plan to change it out.
If the battery has reached 80% of it's original capacity it's degraded and should be replaced before it fails. Any swelling is a failure, if so replace it stat before it destroys the device.
Erratic fast charging is another sign of a battery failure.
