Hey Everyone!
I have an S2 with some trouble...
The phone was not charging at all, kept discharging even when connected to power, so I suspected a Charging system failure...
I proceeded to get a new charging port, and the battery would charge up to 60% and give an error (Battery Disconnected), tried a couple of charging times, never got a good battery life, phone was shutting down unexpectedly...
So, it was time for a new battery, bought the battery like 3 days ago, inserted the battery, tried powering on the phone (hoping the battery would hold some power), it didn't power on at first, kept doing my stuff, and like 3 hours later, I connected the phone to the computer to get some power, and it was powered on already...
Now, the battery life is quite good compared to what I used to have with the other battery, but whenever I power off or restart, the phone will keep turned off... If I connect a charger, the phone will boot and tell the battery is 100% charged...
Now, If I shutdown, remove battery, put back on and turn on the phone, it will boot from time to time, getting a massive battery drain, powers off by itself, connecting the charger without power on, the phone will display a full battery...
Any help will be appreciated!
Kernel Siyah 3.0.31 s2 v6.05b+
Roshnaie Rom V4 LSW
PD: can I try ICS back in this device???
If I remember correctly, updating through kies would repartition the device, and I dont know if ICS would be compatible with that (used disaster Rom before on another i9100 i had), also, I ignore the method used to update
Yep, do a clean install of stock in the first instance & test. Are you sure you bought the exact same revision of USB board that was already in the phone ? Often problems that persist after replacing the USB board are caused by this. If you didn't, you probably want to buy another USB board & replace it again, but use the exact same revision that was in the phone initially. Check KeithRoss39's guide in General for the info you need.

K, will try a stock ICS, feel a lot more confortable with it for trying out the battery stats...
As for the USB board, originally had R2.2, only R2.3 is available everywhere I ever looked for it, will need to order from somewhere else, but the shipping will cost like 1500% more than the actual board, will keep digging around the junkyard
The difference in the board revision might well be causing your issues, but hopefully it's just something funky in the rom install you've currently got. If it's OK on stock, do a completely clean install of your custom rom & test that for a bit.
And if it's not OK with stock, you know what to do.
Hi!
Have you checked your battery? Maybe your battery has some problems. Actually, one of my friends had the same problem..... He purchased a new battery and a new charger for his S2 and fortunately, his problem was gone!
Please thank me if i helped you!
'So, it was time for a new battery'
And so the 'nobody reads threads before posting on XDA' thing continues...
As @MistahBungle says.....get that board replaced for the correct version. I would personally avoid Odin flashing a phone that I knew to have the incorrect USB assembly. I'd also advise you to think long and hard before flashing stock ICS to your phone......if you want to know why.....do a search for "emmc brickbug".........
This might be my S2 or it might be my W, but it's definitely CM...

Hi guys. Today when I was trying to charge my GS2, there was popup said 'battery disconnected'. I've tried to take out the battery for a few minutes, but the problem has not been solved. I am running checkromv4 and siyah kernel right now, just updated to siyah 2.6.12 last night. Can anyone help me? BTW, I am using the stock battery.
Are you able to charge it ? If you are (even tho this probably won't make a difference, but it might), charge it to 100% & delete battery stats in RedPill Recovery.
If this doesn't work (probable), try an earlier build of Siyah. If that doesn't help, go back to stock firmware & see if you can reproduce the problem. If you have no problems with stock, then it would obviously be a problem with that build of Siyah or your rom.
If you still have the problem running stock firmware, it would probably indicate a problem with the battery or something else hardware related. Perhaps try another battery. Failing that, back to Samsung/your telco for repair.
just take out the battery again this afternoon for ten minutes, and the problem seems like sloved so far. I can charge now, but have to take a try tonight. Thanks for your help.

This is an old thread, but I recently had this same problem with my Galaxy Note i717. After worrying about it for awhile and searching to find this thread, I took my battery out and examined it, and of the three terminals, the middle one had a piece of plastic broken off of the battery, covering the terminal. So the phone was getting power, but apparently couldn't communicate with the battery, and so for its own safety, wouldn't let me charge
Hopefully this helps someone else!
-Tom
EDIT: Also I tried charging to 100%, and clearing the stats etc, to no avail.
battery disconnected simple fix
pull out the battery take a 12v battery of your car or UPS touch the terminals -+ to your phone's -+ as - to - and +to+ remember just two or three times kisses only . now put battery back in phone Done....
First....why revive a thread that no one has visited in over 3 years.....
And second.......seriously? Connect a high capacity 12 volt source directly across the phones battery terminals?
To whoever reads this.....
DON'T EVER ATTEMPT TO DO THIS.....
It is EXTREMELY DANGEROUS and incredibly stupid to even *think* of doing it. It WILL destroy your device and it will likely cause you to suffer burns and possibly start a fire.....

I have in my possession 2 galaxy s2 i777s one of which was thought to have a charging problem which is why we got the new one. Once i got the new s2 i tried to put the new battery in the old phone and it not only powered up but it also charged. i then put the old battery in the new phone and it wouldn't charge just like before, i keep getting a boot loop where the battery symbol would flash then go away periodically about 15 seconds apart i would guesstimate, this happens for both phones with the old battery, but both phone charge the new battery. I came to the conclusion that the battery may be the problem and set out and bought a new battery and gave the old phone to my mother thinking problem solved, only to discover the problem still existed, replacement battery wont charge same boot loop. Thinking lightening did strike twice and the battery was faulty i returned it and got another one same problem, boot loop when charging or connecting the usb to the PC. I tried the battery in my new phone same problem, i looked at the specifications on the battery to see if they were the same and yes they were exactly the same:
1650 mAh,
3.7 li-ion
6.11wh
made in china
i have MULTIPLE usb cable that are compatible and MULTIPLE chargers that are compatible and i have tried them ALL. a person suggested i take the battery out plug in the phone then place the battery in while plugged in, didnt work. i tried cleaning the contacts on the battery and the phone itself and nothing, the new phone is rooted but the old one however was bricked in an attempt to root then factory reset, i dont know if this plays a part in it, but remember the battery from the new phone charges in both phones and the the replacements dont charge in any. i had tested the old battery in the new phone before it was rooted or had any apps or anything on it and it did the same thing, boot loop.
any suggestions?
im new to the whole do it yourself root and rom thing so please keep that in mind when tossing certain phrases around.
Edit:
ok after searching some more i eventually found out the reason for this was because the battery I bought was incompatible, though the guys at the store said the battery would work for the i777 which it did, it turns out there is something different about the standard of which the battery was built.

Based on everything you've said, I would strongly suspect bad (or incorrect) batteries. You must have I777 replacement batteries. Ones made for the GT-I9100 will likely not work. I suspect that is your problem.
I know, I know, another bootloop thread. I've been reading dozens of them and I can't find my problem, please forgive me.
My wife's phone was stolen, and so we bought a used one from a stranger after seeing a listing on a local sales site (gumtree). Bad call - they demo'd it for us, but we didn't power it off and on before buying. After parting with cash, we find the phone won't boot unless it's plugged in to AC power (and not USB). All it does is loop grey/green battery logos over and over. Sometimes vibrating, sometimes not, but it would never break the loop, except to enter download mode, unless I connected it to AC power.
If I did boot it, I couldn't do some stuff, like enable USB debugging - it flat out wouldn't allow me to check that box. So I checked the kernel, and it seemed to have a weird kernel installed, so I thought it was time to just re-flash with the official firmware.
Well, first I wanted to try SlimROM, but I couldn't get to CWM Recovery (which was already installed) reliably, and on the rare instance where I could get it to come up, I couldn't navigate to extSD where the slim files were, nor mount USB storage (the PC wouldn't recognize it).
So I decided to try and re-flash to stock, using ODIN and the official samsung FW that worked well on my own GS2. This worked, after a fashion - I could get it to boot if I applied AC power, but things were badly broken. It'd reboot a minute or two after the setup began, and so I was forced to suspect either hardware failure or something that survived a complete wipe and flash.
So I thought kernel. The only one I had lying around that I knew worked was an old jeboo kernel. I flashed it with ODIN, and presto - it worked! The thing booted and stayed stable.
But I still have that accursed battery loop when the phone's off, the battery needs to be yanked to keep it actually powered down. And there are other bugs, like the screen comes on after you turn it off with the power button. Just once, but now it can't be powered down and ignored - you turn the screen off and wait to see if it comes back on and do it again.
And it's confused about charging - this morning it reported the AC adaptor was a USB charger, and this evening it thinks both USB and the AC adaptor are both AC (in the battery info settings screen).
And the only way to get it to boot reliably now is to remove the battery and plug it back in, at which point it boots as normal.
So, after all that long winded four-hours-of-tears-and-anger story, my question is this: What's the battery boot loop all about? Why does the screen flicker constantly when it's charging via AC? Why does it take -twenty seconds- to recognize it has been plugged in to power?
I can't install CWM, it won't enter recovery or boot successfully (no loop, just hangs on the yellow triangle screen). Before I start randomly applying new ROMs via odin, I'd like to find out more about my problem.
Please, can anyone shed light on this? I thought I knew what I was doing but I'm coming up empty here.
Sounds like the USB board/port (tho it might be worse than that; this is what I'd replace first). Relatively cheap/easy to replace; but you do need to check which board is currently in the phone & ensure you get the exact same as a replacement - there's 4 different boards, get the wrong one & you won't fix the problem/waste time & money.
Search for similar threads, there have been detailed threads in Q&A over the past few mths, those threads should have the info you need.
There's also a chance it might be as simple as the battery on the fritz, if you're able, try another one.
But definitely sounds like the USB board (hopefully for you) to me
Thanks for the suggestion. Certainly the flickering while charging issue and the delay to recognize the charger being plugged in point towards a USB board issue, but what I can't figure is the reluctance of the unit to boot without changing the kernel. Wouldn't the stock ROM via ODIN have included the stock kernel? Why does CWM cause the unit to lock up during boot?
Last night the thing stopped flickering on AC and recognized the charger cable instantly - is this a self-calibrating feature? (My research of a thousand similar threads seems to suggest a lot of battery issues correct themselves). For the record, the phone did come with a second 3rd-party battery, but neither it nor my own original GS2 battery make any difference.
So... Yeah, I'm still not sure if this is a hardware problem, software problem, or both.
Also last night I followed a suggestion from another thread and loaded up touchwiz, changed the screen timeout and switched back to apex launcher, and the screen started shutting off as desired. This morning it doesn't work anymore, and the phone is frequently found with the screen turned on. =/
Ok so by flashing full stock rom that practically eliminates the software side of things. Now do what mistahbungle said. My money is also on the usb board. I had to replace mine recently. Click the link on my signature, from there you can get onto a guide by keithross39 on how to DIY if you choose.

'practically eliminates' indeed. I still can't work out why I had to flash a new kernel to get it to boot. =/

Do you want help, or do you want to continue doing what you think will fix the problem? If you're having the same issues on full stock, it indicates hardware issue. The software won't work unless the hardware is functioning correctly. Let me think, what did MistahBungle say was the problem? Oh that's right. The USB board. Hardware.
Oh, sorry, I thought we were having a conversation. Should I not talk until I get the replacement part?
I'm not disagreeing, I'm fully prepared to accept the USB board is part or all of the problem, but I still wonder why etc etc.
OK....so....firstly, flashing a standard single file firmware won't fully wipe the previous software.....all it does is overwrite what it needs to (leaving who knows what untouched). The easiest way to regain a 'clean slate' is to flash a 3 part test firmware which DOES complete a full wipe during the flash..... @Hopper8 s guide provides a link to this test firmware and full instructions as to how to install it.
Secondly.....hardware faults can/do cause unexpected operational issues......some of the issues you describe were appearing on my wife's S2 before I replaced the USB board on her phone (they disappeared afterwards). As @Hopper8 has mentioned, his guide includes a link to my guide concerning the replacement of this part. I personally would hold off doing any more Odin flashes until you have replaced the board......if the USB port fails during a flash (because of a faulty board) you'll end up in a 'whole world of hurt' that will be infinitely worse than it is now.......

Thanks to both of you for the responses. I've taken the phone to a repair shop and they swapped out the USB board to no avail. =/
Given what you've already spent on it (cost of phone + replace USB board), if I were in your situaton, I'd be cutting my losses & put it down to experience rather than replacing the motherboard (with a 2nd hand board from a 'donor' phone), whilst that's nowhere near as expensive as paying a service centre to put a new board in, it's still likely to cost you >AUD$100. If you can get one for a lot cheaper than that, maybe it would be worthwhile.

Or...as first measurement, you clean the pins briefly and bend the holder slightly back to the center.

By 'holder' do you mean the USB port, or the connection inside the phone between the USB board and main board?
It's not a physical problem, at least in the USB port... I mean, we put a new one in it and nothing changed.

Ah the usb board had already been replaced? Okay then forget about my proposal, sorry.

So the next step is either a motheboard replacement or the bin.
I realise this isn't what you want to hear, but think logically about it...You bought a 2nd hand phone from someone you don't know/had no idea what they'd put the phone through before you bought it, it crapped itself shortly after, giving no indications whatsoever the problems are firmware/software related, and showing a number of symptoms which indicate something major is wrong hardware-wise.
You tried the cheap/obvious & that didn't work, one way or another you need to bite the bullet (both options involve you spending a not insignificant amount of money in all likelihood, unless you can score a donor phone cheap).

Way ahead of you. Ordered a new (NEW this time) phone. Will be selling the S2 to the next guy, along with the caveat "Sometimes the screen comes on." Will lose a few bucks, but it'll go into the old logbook of lessons well and truly learned. ^_^
Thanks for your help.
Hello
Yesterday my phone randomly shutdown. After that I werent able to turn it on even after wiping everything and reinstalling the rom. When I came back home i flashed the official firmware with odin and it didn't work as well. Then I managed to turn it on successfully while it was plugged to a charger. I managed to observe that when I normally turn it on it starts only plugged to a charger and turns off after cuople of seconds. This doesn't happen when I enter recovery mode or download mode - I can boot successfully up my device to these modes and it doesn't turn off without need to be plugged. What do you think happened to the device? Can it be fixed on the software level? If not how much do you think it would cost to fix this if it is a hardware issue?

Are you sure your battery is healthy?
Remove your battery and see if it has got any exapndings or swelling? Cause I had the same issue except after losing half of it charge it would suddenly turn my phone off like I'm removing my phone when it's still on!
The battery looks 100% normal. I'll check tomorrow with my friend's battery. But in recovery mode phone doesn't have any problems.
Any other ideas? Can it be anyhow software related? If so is there any option to fix this? What should i try?
Replace USB board/port; quick/cheap easy to do yourself. KeithRoss39 has a guide in General (not stickied, search for 'replace USB charger board' or similar) which has all the info you need to get it done.

But the phone does charge well. And it works on battery in recovery. It turn on normally only plugged into power source and the shutdown randomly. How could changing usb port could fix that issue?
Because USB board problems almost always (at least that's been the experience on here) manifest themselves by showing a few faults & working OK otherwise, rather than dying completely - you might be able to charge OK, you might not be able to transfer data all the time; you might be able to transfer data OK, you might get constant shutdowns which you can't explain by changing firmware & trying a new battery.
Everything you've said in this thread so far points to the USB board, and as this is an easy & cheap fix, if it was my phone, that's what I'd be replacing to try and fix it. Put it this way, given how cheap it is (around US$10-$15), if this doesn't fix it, then you'll know there's probably something more major hardware-wise going on. I wouldn't be taking it to a mobile repair shop to have this done though, as obviously they'll probably charge you a crapload in labour to replace a $10 part. Save that for if changing the board doesn't work.
Thanks for your effort. The problem is I don't think i can do it myself. I don't want to spend much money on this phone cause it is quite old. That is why I kind of don't what to do now
Hello and thanks for taking the time to read this, let me explain a bit first about what happened:
A week ago, i changed my Samsung Galaxy SII GT-I9100 from Cyanogenmod 4.2.2 to Slimkat 4.4.2, and everything was perfect the first day, but then i stumbled upon something that didnt happen before, suddenly my battery stopped charging, it would show its connected, but would go up in %, after trying to connect and disconnect for over an hour i got it to charge a phew % up to 15% and got stuck, so i tried to create a new battery stats with terminal, so i did and it charged for a bit then stopped, so ive been using the phone like this for a week now, i took it to a repair center and they told me it was the battery, since they plugged in a battery of them and started charging flawlessly, so i bought a new battery, but now it kind of charges for a while but gets constantly stuck at a random %, so i unplug and plug back and charges again. So the question here is:
a) Is this caused by a bad rom flash and not wiping anything? i wiped a memory card, but dont remember if it was external or internal, my pictures and everything were still there.
b) Is my charging port busted? wich seems weird because this didnt happen before.
Thanks in advance!
Yep might be the USB board/port (I presume you bought an original Samsung battery ?)
Clean install of stock, test for a few days. If it's still happening, replace the USB board/port. Search for KeithRoss39's guide in General (search for 'replace USB charger board'), has all the info you need; quick & easy to do yourself will cost you ~US$15.
Edit - Actually, now that I think about it...Don't flash stock with Odin, just in case the board is on the fritz. Get one of the CWM flashable stock roms from Wanam's thread in Development & flash/test that for a bit (still do a wipe though). If the board is on the fritz & you try a flash, there's a very slim chance you might brick it (Keith has a theory some of the bricks we see are people attempting flashes with dodgy USB boards).

Thanks for the reply man! i actually put the old battery inside and its working a bit better, never the less its still frisky to make it charge, sometimes it charges for a good chunk of battery then stops, but says its still charging, then i unplug, plug back again and keeps charging, if i were to replace the usb board/port, wich version should i get? my cellphone is the Samsung Galaxg SII GT-I9100, but ive been looking at some charging port replacements and they say something about REV 2.2 and stuff, so wich is the one i should get? This is the one im thinking of buying, is that one the correct one? THANKS FOR THE RESPONDE BTW!
