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.

So, anyone having the same problem here? I already reported this issue to Sony support forum. And yeah, theres alot of people having the same issue like this. The LED will start blinking right after it reach 90% above. Its very annoying to check it all time.
This is happened to me almost everytime i charge my phone. This is kinda software bug, or something to do with rooted or recovery installed? Since i have a rooted and recovery installed on it. Or maybe the problem is with the magnetic cable usb?
Nopee.. Nothing of that sort for me ...

Happens to me aswell connected via USB on my pc.
So, i bought a new brand magnetic charging adaptor called "MAGNECTOR X2". This solved the blinking charging issue. Yeah i was right, theres nothing to do with lollipop update or software. ROFL! I recommended for u guys also.
Stronger magnet
More stable
Can be used with all type micro usb cable
Easy to carry
*Search at youtube "magnector x2" for more detail.

No. Unfortunatelly he doesn't have any other charger.
The docking station isn't original, however it was charging fine on kitkat.

I suggest u try with another diffrent magnetic charger, if the prob still there, do a clean install by using flashtool. Hope that will help, since my problem already solved by changing the usb cable/magnetic charger it self.
For your information, charging your phone to 85% or 90% rather than 100% doubles it's battery life cycle (as in amount of discharge/charge cycles it can survive through).This is something you should care about as the back of the phone is not openable.
I'd want mine to blink after 90% :laugh:

He won't buy another cable due to OS bug, and also he won't wipe his data for sure. We will see if the next update changes something.

redmi note 3 charging fix
I too had the same problem and I tried flashing in fastboot and other things stated in internet. But I replaced charging port newly purchasing online. If your mobile is still in warranty period fix it in service center or replace it yourself. Check YouTube for how to replace charging port. You can buy charging port from eBay or Amazon or any other desired site. Check your phone has 24 or 30 pin in charging port board of your phone. Because Redmi has two variant. If you have any doubt just google it.

Its not about USB cable or USB debugging its just voltage problem.. When I was in middle east my phone is charge normal.. But when I am in India its continuously disconnecting
Don't do R&D..Keep your phone calm for whole night..it will be fine in the morning.

I don't think it's ROM or kernel,
I have the same issue.
It doesn't charge even in power OFF mode, and also with the STOCK ROM.
I changed the charger/cable. doesn't work.
I use an app called 'ampere' and it's saying the phone is discharging. but the cable is plugged.
probably it's the charging socket.

Had the same problem & solved it
Hi,
I had the same problem - when connecting the charger (any charger/laptop etc I tried) the phone started charging, then stopped and started charging randomly.
What I did: Open the phone, brushed the USB board, took dusk and dirt out of the USB port, and it works like a charm again.
I used this instruction video and followed the steps exactly, apart from taking out the USB board which isn't necessary if you only clean it. You will need some tools (most importantly a small screwdriver and an (old, used) toothbrush.
I'm a new user so I cannot post the link. Search on youtube for the video with the title: How to Replace Xiaomi Redmi Note 3, Note 4 , Redmi 4A , Redmi 4 and Redmi 3s Carging port ( Pin )
Good luck.
I have solved this problem
Turn on USB debugging from developer mode then put your phone on charging for 1 full night in switched off mode ...
It will charge normally
.
.
.
Tell us if its work for u ... your feedback will help others
its work for me after researching for 3 days
If you guys are using fast charge or QC chargers with custom kernel, Sorry to say that charging and discharging randomly is because of that. You are gonna destroy zener diode which stabilize current passing thru it. If input current suppress 5V it will burn your zener and your device will completely stop charging. (Only working aftermath way is removing burnt diode)
I highly recommend you guys to stick with stock chargers. Or use kernel that limits its current to 2100mA (approx) (Agni kernel has it) to avoid damage to zener diode.
P.S:- Once you replace your USB board, I am pretty sure that you will face some serious network issue like most of users (those changed board) are facing.
Hello,
I think this is really weird.
After a few days I´m not able to charge my phone anymore.
not on: Aukey QC3, IPhone 5se, motorolla, no name charger, original, my work notebook USB port.
Nothing charge it.
Until I plug it into my home desktop PC.
Can someone explain what is happening?
I think it is a ROM bug, since I could open fastboot and the mi flash tool does detect it. And it is now charging (again) ... this happened the second time now...
Any tips?

Yup, very strange. I think I read something somewhere about a similar issue.
Most people think there USB port is broken. But I think they have the same issue but just no PC which works (as noted my work notebook does not work, but my desktop PC does...) it was also detected in in fastboot mode on my work PC (just to low on power to try) ...
I had a simmilar problem (well, I still have). I removed the back cover and removed the battery cables - and plugged them in again. After a couple of tries it started charging again. But yesterday my phone fell and since then I can charge it only via a huawei charger. The Xiaomi one doesn't work. One thing is for sure... If you get a red blinking while the phone is turned off and charging, you must let it rest for about a minute in order to plug in an other charger and start charging again ...

Yes in my case no charger was able to charge my phone only USB was charging.
So I went to global dev ROM using EDL mode and then went to service center. They replaced it in 30 mins. Also my charger was not working so they replaced charger as well.
