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:

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.

Ok guys, I have a i9100 for almost 2 years now but the last 6 months I've been charging three batteries I purchased with an external charger due to that my phone when connected to either USB or AC power it shows as charging, even if it is off it will turn on the screen an show the battery logo, however, it does not charge the battery at all.
I can even see the battery level going down when it its connected what to me means that there's something with the charging circuit that is not sending the electricity to the batterry. Something important to note is that when I use a Stock ROM on it it gives me an error if I connect it to power that says "Battery Disconected", dunno what on earth that means.
I'd be nice if one of XDA Hardware Guru's could advice me on this matter cuz right now I'm tired of reminding what battery to charge and having a backup battery in my pockets. Maybe a mod to bypass the circuit and charge the battery directly? jus saying.
Hopefull

You can charge the batteries with a external charger, so the batteries are fine.
Did you try reinstalling your rom and doing full wipes and formats?
I highly doubt that the problem can be solved by a mod, it seems a hardware and not a ROM related prob.

My battery started to drain fast few days ago, i thought it was a software issue(some apps). Yesterday i put it on the charger, as i didnt put it, nothing happend, i thought my charger broke, i put it on PC, same, wont charge, now im thinking the connector broke, u put USB OTG memory stick and it reads it normally, so the port is working, tryed factory reset and reflashing offical stock rom, problem isnt solved, also when the phone is in download mode on charger or pc, and i take out the battery the phone stays on, it takes power directly from the charger(this is normal), witch i think confirms its a battery problem, not a phone. Now, anyone faced this problem also? Have expirience whit this, any advice what should i do (im gona try with new battery but its a weekend, no stores working). Any help, any chance its really a battery problem, not a phone?
EDIT: Also when the battery is in, phone off, put it on charger, the empty battery shows, the grey curcle arrow rolls (battery stats are read), then it shows the battery level for a second, and the circles bellow it instead of zooming in and out in movement, it stays at the first for a seccond and then the display turns off, nothing, no red light also.

I hope you are right, i had that problem before, and replaced it, after then im extremely careful and gentle, so i think there are very low chances that thats the problem, i will take it to service later today, its still under warranty
Its probably a faulty battery
I had a faulty cable and man it was horrible
I was on vacations so no shops around, the phone would constantly show charger connected/disconnected and would take ages to charge
Hi all,
My phone cut out at about 10% battery charge earlier and wouldn't turn back on. I thought it was probably just bad battery stats. But now I'm home, even after an hour on charge (and 30 mins on another charger) the phone won't turn on. It also shows up as an unrecognised device in device manager.
Whats weird is that when I first plug the charger in, rather than seeing the blue battery logo, I see an unfamiliar green battery logo as attached.
Has anyone got any ideas on how to fix this? (Tried booting with the volume up and volume down buttons held)
It's also come at quite a frustrating time, I may not be able to reply until Sunday night as I'm off camping in the sticks for the weekend.
Thanks
Plug your charger and Try to keep holding the power button for 1 min.....maybe start

Sadly that didn't work.
The battery appears to now be taking a charge (300mA/h according to a USB multimeter), but I haven't been able to even get SP flash tools to recognise the handset sadly.

That is the conclusion I'm coming to, sadly there doesn't seem to be a UK stockist of the battery yet, but I guess in the mean time I can see if the seller will honour any form of warranty on the product. For now, I'm back on my old G3 and it doesn't even begin to compare. I loved my Elephone.
Bad luck my friend.....I have a samsung galaxy 2 and one day run out of battery and never awake again....weird things
I think it should be cover with warranty.....Is one year in China
Type a email to Elephone support and they must be assist you because the phone is less than one year in the marketing.
I hope you will have a possitive news from Elephone
Thanks, I'll let you know how I get on.
I have the same problem a while ago with the green thing logo while charging , I even try it on wireless charger but it has the same thing with the green logo of battery ...but luckily it charge normally with blue logo
I have seen this on my screen a few times when I ****ed my bootloader during flashing. Device ended up being semi-bricked. I could not flash via SPtools because my device didn't get recognized. I was able to fix it luckily!
Hi all, sorry for the delay in responding.
So, the first problem was the battery. You need to charge it beyond 3.8v I think to get the phone to turn on, probably better to get it to 4v so you have enough charge stored to use the phone. The phone can't charge the battery below a certain threshold (around 3.7v) so you have to remove the battery and use a lithium-ion battery charger (any phone battery charger), these are available for about £2 on ebay.
In my phone the USB port had also stopped working for data transfer. I tried changing the board with the USB port on to no avail.
I replaced everything but the screen in the end to get it working.
Are/were you on stock OS or had you replaced it with another rom? Just for a bit more clarity of the problem.
Following on from a Previous Problem which fixed yet created a newer problem I have:
Redmi Note 4 64gb running on Global Rom with a Battery showing Zero Volts on USB or AC Power. Plugging out instantly powers off.

I have no active warranty as an Aliexpress seller(3+ years a seller) vanished at Christmas. I've no issue taking it apart if I need to replace the battery. Watching a Youtube first dismantle video it appears I need a BN41. I'm going to go presume that my local multitude of phone shops won't stock that battery as I tried two and one asked "How do you spell that?" and another "a what phone?" so I won't be going down that route again.
Only reasonable price I could see online was some Eastern European country and using Google Translate I find these charge about €27 for the battery but it's not in stock anyway. Another is €48 in china. Seems a little expensive considering a Redmi 3 battery is about €7.
Anyway I'd prefer to see if it's software leading into a hardware problem as well before venturing down the route of battery replacement.
Any help would be greatly appreciated.
Brought phone into Repair Shop in my City and asked(phoned few days before hand and no problem changing battery) and it was fine until he says "Supplier doesn't have your battery" so I've to go off an buy a replacement. He says that if the phone will show the battery the connection between the motherboard and the battery is not corrupted as such. I'm also looking at "Chargebattery" in the Engineer Mode under Battery and I can see the following as well
ADC_Charger_Voltage :[4626 ]mv
Power_on_Voltage :[3400 ]mv
Power_off_Voltage :[3400 ]mv
Charger_Topoff_value :[4100 ]mv
FG_Battery_Current Consumption:
[XXX.XXXXXXXXXXXXXXX]ma ---------The X represents the consumption as it's going from about 230.0000 upwards to about 462.00000 and fluctuating.
I've had to order a Battery from Spain(exact spec battery BN41) and also bought a Micro Precision Toolkit and none of my tools are small enough to get those screws. I can see all the stripdown tutorials but alas none of them referred to the exact size of the screws so I ordered a Multi-tool. Hopefully it is just the battery otherwise it's the cost of the phone, battery, little multitool down the drain.
I did a very small driver to get one of the screws out(not exact fit) but the other wouldn't budge and I don't want to thread the head on the screw so backed off for now.

Hey BertieBaron, I'm having the same issue with my Redmi Note 4, I've bought a new battery from Iberaccess, opened the device and installed the new battery piece but it didn't solve the problem, still switching off as soon as I unplug it... it's driving me nuts!
Have you found a solution in the meantime? I'd be very glad to hear from you mate.
Cheers
Nope. Binned it. One Plus3T arrives by DHL in a few hours.

Confirmed to be no Water Damage by somebody with more experience than I. Was it dropped? It was a teenager so anything is possible but there was no evidence of such.
Yes guys i had the same problem now, stuck at zero Percent there's a RED light indicatingit's charging but still ZERO won t go up ...and once i unplug the phone from charger it turns off Instantly ....I foudn the Solution for that it s quite easy as u think .. all you have to do is :
1-unscrew the 2 screws bottom
2-becareful while taking off the cover u need to take off the Sim tray
3-and slowly take off the over there s the finger print sensor cable unplug it
4-once the cover is off u see 2 cable next to each other one of them is for the battery ...Doesn t matter remove them both and hold power button for 20 seconds
5- make sure u do keep holding the power button for 20 seconds .....do that like3 or 4 times to make sure no power is left inside the phone ..
6-plug everything except the sensor and power on the phone and check this worked for me
Once u see it worked turn the phone off and put back the sensor and get everything back to together .....Don t plug the sensor while it s turned on i have no idea if this damages anything!!
Hi everyone, I meddle in the discussion, I have this problem. I have a Redmi Note 4 Global, a few days ago it turned itself off. I tried to turn it on again and it worked, then obviously the battery ran out. Tried to charge it, the screen turned on with the "mi" logo, red led at the top but it gave me completely empty battery with no percentage. I thought it was the dead battery. I changed it to a new one and put it in charge. Now I see Mi logo and 47%, it does not charge the battery unfortunately. Stopped at 47% for hours. The battery therefore does not charge. Even if I connect the phone to the PC, the charge does not start and the PC does not recognize it. What could be the problem?
Thank you

The seller assured me that the circuit is good. In the reviews people didn't complain about the fast charging problem.
I am using the original charger and before changing the charging port, it charged normal and fast.
In what sense to change ROM?
