May be its time for u to replace the 'Batt' .
But before hand try with an alternate Batt (may be one from ur friend's phone) and see if the same issue persist's or not .

Ya the boy is around 2 years old so maybe I gotta replace it

nope that didnt work damn it lol, its not a big issue at the mo, but on resale point of view its not good
Check your settings.
Go into developer options and make
Sure " stay awake " isn't checked,
As this forces the screen to stay
when on charge
Sorry just re read your post
and see exacly the opposite
is happening with your phone

Which Rom are you using??
This problem started when I flashed the 3rd preview build of cm10.. after that I flashed back to stock ics but still the problem was there.
If you put the battery back in immediately after pulling it off, the phone will turn on again by itself.. you have to wait for some time and the put the battery back.

I will try that see what happens, took battery out for 2 hours see if that worked and nothing
Sent from my GT-I9300 using xda app-developers app
Try re-flashing? Otherwise return it.. should be covered by the warranty
Had the the same issue, only a complete wipe solved it for me.

Go to settings-storage-other and tick everything. You will loose some data. Then reboot to download mod and flash firmware again. Now the problem is solved!
All sorted thanks to uvaman, used task manager shut down running apps took battery out and left over night, thank to everyone that gave advise

You probably did that but give this a try: remove the battery from your phone for a full minute, if you have a Volt meter at home see that the Volt is above 3.74V that mean you have above 19% battery.
put back the battery without the charger and try to open your phone, see if it turned on.
That just looks fried, never had issues with that batt?

Ever, i mean, before upgrading my android, u didn't
Sent from my GT-N7000 using xda app-developers app
Sounds fishy to me, I don't think JB leak can kill a batt.
Try another s2 battery and see what happens.
U can also charge it manually.

So u say that is impossible to be able android problem?

Nothing is impossible; highly unlickly would be better suited.

Hi friend,
If u sure with your battery try to get external galaxy s2 battery charger and then try back... Good luck:fingers-crossed:

Battery is not charging correctly

For a while my phone is taking a lot much time to charge than it usually take earlier.
So today i installed this app:
https://play.google.com/store/apps/details?id=com.abmantis.galaxychargingcurrent.free
And after i connect my mobile to charger this app usually shows that my phone is having max current:400/500 which shud be 999 instead. (Read app description)
After i disconnect charger and connect it back 3-4 times i get a rating of 700 or sometimes even 900(max) but after letting the mobile charge for a while this automatically decreases to 300-400.
And also from the time i bought the phone(4 months back) charger usually gets somewhat hot(not warm) but i ignored that issue.
So what do u think the fault is in-charger/phone?
Sent from my GT-I9300 using xda app-developers app
Do not use such an application, let the phone discharge to zero to turn off and recharge to full.
mostly help.Please use the phone menu
charging problems are mainly related to cable!
sent from my GT-I9300 running Mac OS
The app has 10000+ downloads and my friend suggested so i thought of giving it a try
After the battery fully discharges and phone turn off shud i turn on the phone after connecting to charger or shud i let be off till it charges completely?

Yea my friend had the same problem and he installed this app as well and was getting 400 too
But then he changed his cable with blackberry cable and now he's getting 900 rating

No need to use this.
just delete the cache occasionally a classic way to charge your phone battery runs down.
It does not have to be zero!!
yeah me too using BB cable. better than many original samsung cables.

Sorry for being noobish but how to delete cache?
By going to application manager> running>show cached processes and then deleting of every program one by one?

If you do calibrate batteries and erase cache, the system will be as before.
Have tried both i.e. cleared cache and charged completely frm 2%
But it almost took 6-7 hours
So is the problem in cable?
Sent from my GT-I9300 using xda app-developers app
Cable
Charger
Usb Port
Battery are all possible causes of very slow charge .

yes it's the cable. many samsung customers including me faced the same problem. just change the cable.

Weird battery issue!

Hey
I have aproblem that is so strange!
For example when I turn off my mobile it restarts!
Even if I pull out the battery and put it in it just power on automatically! !
Sometimes if the phone successfully was turent off, when I press any button it indicates that it is charging!
And now the battery is full even though am using it for around 2hrs
So my question is: is it a phone hardware or battery issue?

mine was like that after moisture damage and then a wrong charger it gets ok after time, it started charging the battery to 5.00v instead of 4.2 n all, stop charging that battery at 95% for like 10 charges and it will come back to normal in no time

as i said it just went away after a while i think the problem is being caused by overcharge, so when u keep charging it to 95% the voltages come back to normal.
In other words charge it till 95% for like 10 charges and it will be fixed.
Well gonna try and reply back thanks

[Q] My note shuts off as soon as Rom boots..

Hello, I am having a problem with my note and it is scaring me. As soon as my note boots it is shutting off completely and restarting. I was just using it with fine last night. I had the uber kernel installed and oced to 1.9 cpu but it wasn't even that hot.. After thinking it was the Rom that was causing this I did a complete wipe and flashed the candykat Rom, upon boot when the cyogenmod log in screen appears it shut down and rebooted again.. twice. I'm hoping nothing is damaged internally. I am able to stay in the recovery just fine without any problems. Please help me.. And when I say shutdown I mean insta black screen and reboot..

Idk if I will do that lol. But now I think I know what the problem is. So yesterday I was using my note and it shut off. The battery was full and when it restarted the battery all the sudden dropped to 60%. It turned off again and went to 1%... I thought it was glitching when it said 1% but after amin it shutdown due to low battery. One thing I then tried was having my phone plugged in while using it and I played games, used my phony heavy and what do you know.. It didn't turn off. So I'm thinking I have a bad battery. PS: I took my note to a pawn shop and they said the battery was bloated. He said it wasn't supposed to spin while on a flat surface.. What do you think?
It seems while I'm playing a game the battery heats up and that causes shutdown cause I'm typing this and I don't have my charger plugged in and its fine..

Yes a bulging battery is a sign that it's bad. Batteries are cheap. Especially on eBay. I buy an extra battery and charging dock for all my devices. This way one is always fully charged, and I don't have to plug in the device unless I need Odin or to file transfer. I learned that lesson 2yrs ago when my usb charging port went bad.

If my power button was stuck would I see the shutdown menu before it rebooted, shutdown, reboot, sleep, etc? I'm just trying to make sure my battery is the problem.. I don't want to deal with a power button..

No you won't see the power menu. It just keeps restarting. I don't think you'd even see your home screen because it restarts before the rom loads.

Oh well then. That's awesome because I'm able to use my phone for more than 5 mins without it shutting down. It usually shuts down when I start playing a game or something intensive. So it has to be the battery! I'm really happy.

Well my phone shut off again when using another not as bad but still a bit puffed out note battery. I don't understand what's going on here... I'm scared to buy a new one thinking that It won't work still... my phone never turns off as much when the charger is in... But guaranteed with battery only. Less than 10 mins.
