phone shows charging even though its not plugged in into anything - Galaxy S II Q&A, Help & Troubleshooting

I had installed checkrom v4 with siyah kernel 2.67 on my phone and friends phone, both are runing exactly the same rom and kernel , but now his phone has a problem where wben he power it off than on he gets a battery charging screen , even though nothing is plugged in. His phone won't boot until he plugs a charger in . Not sure why it does this since it was working fine last week, and this just started yesterday. Anyone know what could cause this ?

Strange, try clear cache and advanced/dalvik followed immediately by flash the latest
Siyah kernel 2.6.11

There are threads on this already. It's usually a hardware problem - the charging port. Some people have fixed it by cleaning the charging port with some chemical cleaner.
I had the same sort of problem when I had the S1. It fixes itself when I left it plugged in a charger for over a week. I think it was caused by a rain drop getting in the charging port.
Probably just Google the problem to find the other threads etc on xda and elsewhere.

The issue seems to be fixed for now... What I did is full wipe data/cache/dalvik 3 times followed by re install of the Rom/kernel and now on the third wipe/re install that problem doesn't happen anymore , which is very odd. I seriously thought it was something to do with the charging port but now since its fixed I don't know what to think anymore. Thanx for the input guys.

It seems either the charger end point / connector and/or the phone MHL port which you connect to charge are dirty clean them and try again.
I've tried to charge it with a different battery charger and tried to clean the phone's USB port blowing in it but nothing seemed to change. I really don't know why but today after 3 hours of problems my gs2 started behaving correctly...but when i reconnected the phone and then I unplugged it the bug reappeared... since the problem appeared for the first time I switched between different roms but always the same ... could it be still a software problem?

hi
i think it's a hardware problem. go to service to check the phone.
Have you droped your phone in water or left it in a mosit area? Maybe rust or something is causing that

Mmm not really, the problem appeared the first time one day i got up and i unplugged the phone as usual... the phone never dropped into the water or something like that..
Moreover if I don't plugin the phone it works normally... The problem seems to appear sporadically immediately after being connected to the battery charger...
Anyway my device is running a custom rom Samsung won't get it back

You can always flash back to stock and reset the binary counter using a usb jig..

Battery say charging no charger connected

Hi guys i flashed D4 v9 yesterday coming from previous d4 roms always clean install but i formatted everything before flashing v9 so i had a clean garbage free phone. I noticed that it says charging but no charger was plugged in. Every few minutes i also get charging paused voltage too high. So me thinking i must have deleted something important reflashed v9 same problem.
This morning i thought i would flash neak kernel see if that would do the trick same problem so what exactly have i deleted and can i rectify it. Iv had a look around the forums but cant see anything to my specific problem.

[q] battery problem after flashing new rom on sg2

Hi guys ,l need help here .l recently flashed NEATROM LITE on my SG2 all went well but later that evening my phone started shutting off and saying charger connected when its not ;l managed to boot to recovery and restore back to my previous ROM which was JB 4.1.2 stock by Sam and Phillz kernel. but now wat l have is massive battery drain and when charger connected there is a delay in it being read .battery manager has inacurate readings too .instead of discharging when of charge it says not charging . what could have gone tits up now ?
Check your battery pins or charger port. Sounds like you have damaged something.
Also try a different battery to rule that out.
I have had a look at the pins but nothing seems evident

[Q] Very slow charging galaxy s3

Hi,
Since 1 week now I have some huge difficulties to charge my GS3. For exemple when I plug it before going to sleep, in the morning there is only 50%. Sometimes I plug it and it stop the charge itself (not at 100%), i have to move the cable a little to continue the charge.
I tried several cable and plugs, nothing change.
Does anybody experienced this? What can I do?
Ps : I already read this post but I didn't find any answer.
Thx
I presume you charged the phone through the AC power? I had similar issue prior which was resolved once I wiped my Battery Stats. Is your phone rooted?
yes my phone is rooter I have omega V35 ROM and i already tried to wipe the battery stats and nothing changed
Im sure you have also clear cache, wipe, reflash the ROM? Its highly unlikely that all of your chargers are malfunctioning, If the phone is still within the warranty period, it may be time for you to visit Samsung Service Centre (SSC)...but unroot first!
same issue here

no i didn't tried to reflash the ROM cause it was working great with this ROM before, I contacted samsung and they will repare it but i need to find the bill first. Is it really necessary to unroot the phone? Installing a stock ROM is good or is there something else to do to unroot it?

unrooting is in reference to returing to stock ROM. SSC will invalid warranties to rooted phones.
i just reflash the ROM and the phone is still very slow to charge.
I will send back to samsung i think.
i just installed the Omage ROM V38 and i still have the problem, you can look at this graph :
Take battery out for 10 minutes. Plug back in and see. If not possibly battery port issue, my wife's had to be sent back for it.

So different USB cables didn't helped? That usually does the trick. Other than that try kernel such as yank kernel which allows fast charging option.

First flash STOCK ROM and see what's gonna happen.
If the problem still persists, send your phone for service.
Make sure there are no signs of custom ROMs and Kernels.
Solution is the CABLE
Here is a confirmation of the solution from Turkey: It IS the CABLE...
Check the cable end that goes into the S3, if you see 5 places but with only 4 wires, it charges VERY slowly... However, I used a $5 charger which had 5 wires in the end that goes into galaxy S3 and voila!

Can anyone confirm this?
My stock Samsung cable has those 4 connections instead of, what looks like the 5 that can fit in. And it charges so slowly!
9/10 its the cable. I don't know bout what is said above. Mine charged fast then suddenly started charging slowly. It was to do with the kernels usb charger stability detection.
Changed cable and all good

So if I install stock Android, will that change the kernal and therefore fix the issue?
I don't see why I should have to pay and wait for a new cable, even if it's only a few quid and a few days :/

All Samsung kernels have the detection. Whether changing the kernel or cable fixes it or not is not knowable.
all you can do is try. can you not borrow a cable to test it? Surely you know someone with a cable?
yes, mine s3 to does charge slow i have the Purelook HD rom please help, take my phone on charger from 4& next morning about 50- 60 & only charged!!
I have a similar issue here, although my problem only started with latest arhd 25.0 Rom, never had this with previous roms of arhd....some times the charge is very fast , then next time it will charge to 19% then stop, then next time it's fast then will be very slow... very intermittent, I have changed chargers. Still same results, going to try wipe the battery stats to see if that helps.

Phone acting weird.

Recently ive been getting this thing that my phone wont charge on an AC charger straight away.
I have to plug it in my PCs usb cable, then plug it in AC so it will charge i have tried 3 different AC chargers , all Samsungs original ones!
It stopped doing this for a cople of weeks then started again.. ive also tried a couple of roms but the rom doesnt seem to be an issue.. Atn im running NeatROM 4.2 with the stock PhilZ kernel.
Any ideas??

Clean install of stock in the first instance to rule in/out hardware issues. If it happens with a clean install of stock as well; Clean USB port, then replace USB port/flex cable, then return to service centre as probably issue with charging/USB circuitry if the first two don't help.
Okay, ill try an Stock install when i have time.. service center is not an option since i bought it used and doesnt have an warranty anymore.. if i cant get it fix i think ill sell it and let someone else deal with the issue, lol

Might want to check battery stuff as well while you're at it; clean the contacts in the phone/on the battery, maybe try another battery depending on how keen you are. Given how long the phone has been out, original batteries should be starting to die off in their droves right about now (and earlier if you charge/discharge a lot).
