So.. I have googled the crap out of this problem and seen loads of issues raised, but nothing solved.
I am coming from a Dell Streak and grabbed me a galaxy s 2 from craigslist a couple months back.
It has been running fine and I have tried a few roms/kernels and a few days ago I got the following error:
When charged to 100%, I get the notification to unplug, when I do, it sticks. No big deal but even when the phone battery has dropped to around 80% it stays.
It does not go into MTP mode or think it is plugged in via USB. Although, before this problem originated, the phone continuously vibrated between charging and not, when not plugged in.
I have calibrated the battery, tried a mixture of roms/kernels and I am now on unrooted stock. The problem still occurs and sometimes it does not recognise a USB connection, like today.
Probably worth mentioning that when turning on (and not plugged in) the phone does not turn right on, just boots into the battery screen and flashes between the battery charging and the overheating symbol.
Anyone got any ideas?

Turn off the phone and put it on charging. Once it beeps that its fully charged, quickly unplug the battery for 5-10 minutes. Should work and 'recalibrate' your battery

Thanks, giving a go now.
Do you need root to calibrate though? I am on stock firmware and not in front of a windows machine to use ODIN.

OK, charged to 100% and got the full notification.
Left battery out for 10 mins and whacked it back in.
Turned on and it went to the overheating sign again.
Booted into the samsung recovery and I can boot into android from there.
Battery says it is as 88, cannot calibrate as I do not have root atm.
Any ideas?

Get root and use the battery calibration tool from the market. The best idea so far. I suggest rooting with CF-Root, its fast and easy - its basically still your stock kernel but just with root.
If you really need the warranty or you'r scared of root you can install cf-root, calibrate the battery, then re-flash a stock kernel (unroot)

If i helped you, press thanks. Thanks.
Done and done.
Calibrated, even bought a new battery. Tried various other roms and appears to be an issue. Phone knows when USB is plugged in but does not seem to recognise the unplugging of the charger. And stays at 100% for a while before dropping down to like 80.
One thing to note is that this seemed to happen around the time of buying a dock for the samsung from Amazon, by Kidigi. I plugged the phone in to the dock without a USB cable connected to the dock and the dock LED lit up, making the phone think it was charging. Is this likely to have caused it/messed up the micro usb forever?
Thanks again guys!
well i think ive figured out what the problem was
Its due to overcharging or keeping the charger connected after battrey is full which has caused a hardware damage
im not sure if this is true but this is the closest explanation i can get the phone shows connected to charger even when diconnected only when i keep it connected for long time even after its battrey is full my usb connection has completely stopped working

well that the same problem with me when it shows connected to charger at 100% i restart it then the phone drops to ~80% battery although its 100% which makes the app battery monitor widget think i have a 1977mah battery while i have the standard 1650mah battery this must be the extra 20% which disappeared after the restart for me
I thought it may have been an overcharging problem, although no other phone I have owned has had this problem.
I let the battery charge all the way down (it stayed at 1% for about 3 hours) until it shut itself off. I left it on the side and it created a clicking noise, it was trying to turn the phone on as it knew the battery was in, even though it was depleted.
I plugged it in via USB to charge and it tried to turn on straight away. Shut it down and charged by plug until the 100% notification then turned on.
Still the same problem but one of my battery widgets warned that the battery was over voltage for a while before calming down.
If the phone cannot be off with the battery in, what could be causing that?

It has been known to be caused by a defective circuit board for the USB connector.
So, it needs a samsung return, I assume?
i have the same problem with overheating and usb plugged when there is nothing connected
i changed the usb port from the phone but it still having the problem!!!
i will try to put a new battery and see if it work and after post a reply
Hi all,
I have an AT&T Samsung Galaxy S 2 (i777). It was rooted and running CM 10.1. A few months ago it started to have charging/USB port issues. Some of the symptoms:
-Sporadic charging (starting and stopping)
-Required USB jiggling to get it to start charging
-Sometimes wouldn't charge at all until it died, then would eventually charge while powered off
-Would not shutdown (only reboot, even if the battery was removed)
-Randomly started "car mode"
My initial thoughts on this were USB port issues. After doing some research on people with similar problems, I tried cleaning the port with alcohol, toothbrush, compressed air, etc. No avail.
Eventually the phone just stopped charging altogether. At this point, if I left it plugged in, it would sit in a continuous boot loop (boot, get to lock screen, realize it has no juice, shutdown, rinse, repeat). After a few days of attempting to charge and just having that happen, it went black and has never turned on since.
To try to solve that, I bought a new USB port flex cable on eBay and replaced it, assuming this would solve all my USB port issues. I tried to be as ESD safe as possible and also not break anything in the phone, but after replacing the board, it still wouldn't boot.
Next step- bought a new battery with an external charger to skip the USB port altogether and see if the battery was shot. Charged up the new battery, popped it in, nothing.
I'm at a total loss. If it started as a charging problem, I don't see how the problem could have been anywhere but the flex cable board or the battery. Does anyone have any ideas about what might be going wrong? I would REALLY appreciate some insight.
Thanks!
Maybe the repeated loops damage it

Did you ever find a solution? I'm in the no charge boot loop after letting it die last night.
I have not seen previous usb problems at all. I suspect that my battery got over-drained, but then I've got the same symptoms as you and you have a new battery. I can get it into recovery but t won't stay on in CWM for long enough to fix permissions, which is the only thing I've tried so far in CWM.
Thanks
If i was in your place i'd have taken it to the nearest Samsung Service center and let them fix it for me.
I think the fluctuation in power may have damaged your phone battery point from where it takes power from the battery and charge it.
Maybe it has damaged the motherboard.
We cannot say anything in this situation.
You should just take it to your nearest service center.
Best of Luck
OK, wiping Data fixed it.
Thanks for your reply. This problem just started this morning with no previous issues, doing the looping part of your problem that I quoted. so it's not a question of what I might have done.
But, for others encountering my part of it, here's what I've done and learned so far today.
As I looked into things elsewhere on the , it seemed to be a software problem. Luckily, I have another Galaxy (Exhibit) that's similar battery and I was able to put the charged battery from it into the SII. The SII booted and worked fine but did not charge. I put the SII battery into the Exhibit (sorta fits). It took a charge.
This confirmed to me that it's not the battery. It must be the phone perhaps USB port or more likely "firmware" since problem started abruptly after draining battery down.
I then wiped data on the SII from CWM/recovery and rebooted.
SII is now charging again. Stock battery is back in and working.
Time will tell if all is well, but here's what I think happened:
1) battery drained down to zero while unplugged
2) plugging in and starting up phone immediately threw something off in the battery stats at a low level...that kept it from charging even when turned off. Or rather threw it into a loop. Don't really understand this stuff, but may have to do with physical things that happen in a battery when the cells drop down way low and then the voltage feedback they give to charging circuit.
3) charging battery in another device (gingerbread, by the way) got the battery out of this, if battery had been a contributing factor,(or just a trigger) it was back over the hump.
4) wiping data fixed the charging, so I conclude it was a charging circuit data issue triggered by an ultra low battery.
Hope I'm over this problem and hope that it helps somebody else. If you run into this yourself with no previous USB or hardware issues, I'd suspect software before hardware. If I had only one battery and no way to charge it externally, I would suggest get one of those simple universal clip-on chargers to bring the battery back up and then go into CWM and wipe data.
UPDATE: It's stopped charging again. It's no longer looping since I got the battery charged up, but not right either. As soon as I plug it into a USB, it boots itself without powering on.
I guess that this is looking more like a physical USB issue now. Weird that there's been no previous sign of trouble before today.
UPDATE2: I cleaned USB port but no help. Then I bent the USB contacts towards the screen and it is charging now again. I'm ordering a replacement USB.
I should add that I'm running Shostock Jellybean, older (not current) version with it's associated Jeboo kernel. Don't know if it matters.
I wish I'd seen your post sooner.. I had exactly the same problems back in January. Took all the same steps you did. In the end, an 8$ USB flex cable from EBay solved the problem. I think you'll have luck with that:thumbup:

hey, I'm experiencing the same issue slightly different.
-Sporadic charging (starting and stopping)
-Randomly started "car mode"
-plugged in the charger while the device is switched off, it automatically turns the device on.
-If the cable still plugged in while the charger removed from the main current, it shows "Charging stopped. High voltage"
-From yesterday, it doesn't charge even. Only way to charge is, connect the charger first and then Restart the device.
Then only charging continuous.
Can anyone help to solve this? Is this a software issue?
Thanks!

Also, there was this issue early --> when I charge it from the laptop, the USB mode doesn't switch on. It just charge the phone only.
But now it's not even working like that.

hi, my s2 wont charge. It just shows up charging when plugged in but it doesnt charge at all. and it overheats too much while plugged in. What is that flex cable you said, is it the one that connects the charging port to the motherboard? were you the one opened and replaced it? thanks
Hey,

I see that the phone is powered off, and plugged into a charger. Unfortunately that is a known bug of OMNI on this phone, and I am not aware of a solution beyond avoiding this condition. The phone will boot fine once you unplug the charger. leaving it plugged in may discharge the battery completely. The quickest way to charge this device on OMNI is to plug it in while booted into recovery.
What firmware are you running? what have you tried?

So you bought a battery. Was it new? Are you able to verify that is has sufficient charge? Have you tried an external charger? Have you tried to enter download mode? (to allow the pfone to be powered by the usb-port)
I ended up having to bring the phone back to the store to have them replace the battery. I read somewhere that the Galaxy S2 phones can only charge once the phone is on. However, the battery must have enough power to turn the phone on before it can charge, If you completely drain the battery, it won't start so you can't charge the phone. It is an endless cycle of stupid. I purchased an external charger on Ebay so I can avoid the situation entirely.

when i put the phone to charging, it have 10% of battery, but phone turned off and i get same problem as in the video.
I take the battery of my friend, he also have an i777, but don't have this problems with charging.
And another problem was that i left phone in stand by 7-8 hours with 70% of battery and when i check it in the morning it was dead.All apps was closed.
My phone got turned of suddenly while i was on a call and its not getting turned on . I thought it might be the battery and kept it for charging. And tried after 2~3 hours, but still the same. Its not showing any charging animation ( with the battery icon ) while i kept it for charging. I tried to plug nd unplug the phone so that it shows that animation , but it doesnt show up.
I searched in forum and did soft reset and hard reset ( removing battery and hold the ON button for 10 seconds and insert battery again and try). Even that didnt work out.
Does anybody have any idea on what might be wrong?

Try USB JIG?
It will force you to go download mode. Head over here to check out about usb jig. You can make your own self too. If let's say you're able to go to download mode. Then flash stock firmware.
Try to find somebody else with an S2 and see if you can borrow their battery. If your phone starts, then your issue is with the usb port itself........
From your description it's either this or the battery has suddenly failed, battery failures are *extremely* rare.......
New software is NOT NEEDED in either case.....

Also, if you *can* get hold of a second S2, see if your battery charges in that one......that would help to confirm or rule out any problems with the battery.......

Hi guys, hope you might be able to help me out. So from one day to another, fast charging does not work anymore with my Galaxy S9+, its not rooted and I am still on stock rom, with newest patch level (December).
I tried rebooting (plenty of times), I tried Safe Mode, I tried turning the fast charging option on and off, tried different fast charging chargers and cables (which used to work before) nothing.
Maybe do you have a hint what I could do to fix that problem.

I had the same problem once. I noticed that an app was draining the battery. I uninstalled it and restarted the phone. Then, I got the fast charging back. May be check your battery usage to check if something is consuming more power than usual.
I have the same issue. Been like that for months. Try cleaning the charging port. I had to do that to stop moisture error message and helped it charge. I still have no fast charge.

N still no fast charging? Sorry if it's a repeated question but ur using the original Samsung charger n cable right?
Solution: Fast charging
Go to settings-apps- enable system apps - find usbSettings (clear cache, force stop). It should do the job. At least for me did. Stock Rom with latest security patch (Sept 2019), 8.0, Galaxy s7.
Reasons: latest security patch, or that battery drained to zero just before my FC stopped working.
Hit thanks if it helped
