People have probably ignored your topic since its already been asked/discussed before so all your doing showing people you cant be bothered to search.
Flash custom kernel via download mode like Siyah v5 and issue should be gone. If not flash whole stock rom.

If its less than 2.5 months old and not modded I would strongly just suggest taking it in for warranty. You might as well use that warranty while you have it instead of looking for tweaks or settings on here.
Other than that perhaps try cleaning the power contacts on the phone and the battery with a Q-tip. Has your phone also been exposed to water, steam or sweat? These can all lead to water damage

Hey thank you for the reply. No my fon is not exposed to any of what you mentioned.
I will take it to the service center rite away.

hey guys as earlier suggested to me i took my fon to service center they ripped my new fon apart after that they told me that my fon requires software update and my fon will be formated. .
but the problem is still there even after taking it to the service center. . what now it still shuts down randomly once for aure after full charge. then only turns back on after batter reinsert or i start it using debugging mode (vol key up + home + power) then from there i choose reboot. .
any more suggestions please??

Did you flash any custom ROMs or is your phone completely stock?

First thing to do is to check the battery condition.
Put the phone on charge, then plug in the battery. Is there any heat as it charges?

yes there is heat .. i don't think the battery is dead .. when i removed the battery it was on charge and fully charged ..
sorry sorry there is no heat tell now
You have no recovery mode to try a factory reset .
In which case you need a service centre .
jje
so that's it i have to return the phone for the second time ..
and what is about the battery heat there is no heat does that mean the battery is dead or what

I just tested it and apparently no, won't turn on or go into either recovery or download mode.
You might get lucky and its just a faulty battery or your phone might really be dead. Either way your all set as its under warranty...

Battery charges while unplugged!?

Hey there,
My phone drained while plugged in and I noticed after I unplugged it the charge began to climb. Ideas? Anyone else?

Dont want to be the pessimist but my brothers phone did this. He sent it off to samsung and they sent him a bill for £150. Apparently it was water damage. There are other threads on here though have been diagnosed as faulty USB connection on the main board.

Well it hasn't touched water.. seems the charge count has stopped going up.

Neither had my brothers, apparently its sensitive that the slightest condensation can cause the indicators to turn. Thats what they told my brother.
Ricey
Just an Android bug.
When charging, the phone thinks it's draining, so it says; it's losing power.
When decharging, it thinks it's charging... Phone Samsung, send some photos (with the phone) and make sure the water-sticker has all it's crosses VISIBLE!
If you don't want to risk a bill yet, then try flashing a different ROM... (First, backup, incase it doesn't work, flash stock ROM via Odin, if that doesn't work, try a different custom ROM, if that doesn't work, you phone's f**ked...)
I will try this tonight when I am home. Thank you for the input. I will post results

Phone will not charge now..
OK... didn't have a chance to flash a different ROM. if anyone has any suggestions on which rom to go with I would appreciate it.
Today it seems that the battery will not charge. It sees that it is plugged in but it does not take charge. The saga continues! I am thinking about getting another battery just to test this out.
You must rule out bad roms by flashing a stock rom .

Common bug.
What seems to happen with mine is that the battery miscalculated the amount it's drained by when you use it for a while - For example, using google maps as a car GPS. After you get to the destination, and turn off the GPS and Data, the battery APPEARS to regain charge - it's not really, it's just recalculating the amount it was drained by.
A battery refresh will sort it, it's also very common if you reboot/crash at under 50% power. It reboots at around 10% and ticks back up to the 'correct' value after an hour or so.
It gets worse after a few weeks of use, and a battery refresh (full charge, shut down, remove battery for 2 minutes, replace battery, fully charge, switch on), sets everything back to default again and it behaves itself for a while.
Not had it happen for a couple months now, but I've not been dinking around with flashing stuff of late so it's not been crashing horribly (which was the main CAUSE of this bug), in the first place.
Here is some news... tried a different USB cable and guess what? No more charge issues or over voltages.

Don't buy a new battery!
Before paying for anything;
while the phone is running, pull the battery...
2. (Leave the battery out) Plug your phone in, if it recognizes the charger, leave it to clear the RAM properly, plug the battery back in, boot into CWM and wipe battery stats! Once done, take from charger, unplug battery, plug it back in, then leave the phone powered down, and plug charger in. Leave it for an hour or two, then boot into Android. Now it should work fine
It's a problem with your usb charging port. It will progresssively get worse and ICS will keep telling you that its paused charging due to overvoltage. 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

[Q] S2 completely dead but unlike other problems

Well I was taking a video and I stopped recording and the camera app froze and I couldn't get any response out of the buttons but the camera app still showed the camera and that was still working so the phone wasn't actually frozen. So to turn it off I held down the power and home button and the phone turned off. Ever since then my phone won't turn on. I've read so many forums and I've tried so much e.g soft reset, hard reset, download mode, upload mode, USB jig and nothing works. When I put the phone on charge the left side of the camera gets warm (not hot).

The battery had 50% charge before dying
You can change the mother board but it will be costly. Do a JTAG Repair.

Any other ideas where I don't have to spend a lot of money. Also I haven't tried a new battery but I doubt that's the problem because the phone
froze before dying
you should try another fully charged battery first................usually when my phone freezes for some time and when i take off the battery and re insert............i usually lose 10-30% battery, sometimes more than 30%

You have three options left to try
1. Re insert the battery and charge your phone then try to restart
2. Try to reboot it in recovery mode
3. Send back your phone to claim warranty if its only 2 months old

[PROB] Charging issue while phone is connected to charger

Hi guys, I am facing a problem regarding charging. Sometimes when I connect my phone to charger, it not used to charge up my phone. The phone itself shows that its being charged but the charge starts to reduce while charging and then turns off. When i reboot after 30 minutes, it shows 1 or 2% charge and then again after sometimes get switched off. Several times I have faced this isuue and the main problem is this issue wont happen every time, so I cant go to service centre too. If I ask for replacement, they will ask me to show the problem but if the problem vanish, they wont do anything. So if anyone else faced this issue and have any solution please help me. Thanks.

Hi,
I've actually faced a similar issue (perhaps not the same). It was the very first time I bought the phone, to many charging troubles. The phone on connected didn't show charging or sometimes say "Not Charging". I had to turn off the phone and get it somehow to charging mode left it around half an hour - then after some tantrums the phone once turns on - displayed charging like 12% already. Thereon the charging went OK. So perhaps there is some issue with the OS's calibration with battery.
Once I allow the phone to go less than 10% with dual sim on - the problems re-appear. Most probably, on initial usage - allow battery to completely Charge and then discharge for 3-5 times then the charging woes dwindle away. Hope this helps. Cheers!

The prob is in charger. May be there is some loose connection in the charger itself.. simply go to service centre for a replacement of ur charger.. In my case the phone is charging as usuall with an another charger..
Sent from my GT-I8552 using Tapatalk
There are two reasons why this happens one is the problem with the firmware of the phone, and the other with the charger, u use any other charger from samsung for a period and see the problem is still there. If this persists, run to service centre and ask them to reinstall/flash your ROM.
Probably it will be with the charger, and when the SC personnel checks they wont agree with you for a problem in the charger. Better you check it with another charger.. :good:

It was charger peoblem.. Samsung SC personnel was denying that its a problem and even harassed me. Next day I went their with proof of my problem and they told the problem is in data cable part and as my phonr is 4months old, I wont get warranty.. Next day i called samsung call centre and confirmed myself about the warranty and abused the manager of that SC for telling me lie and then he replaced the full charger set without saying a single word..
