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.

Hey guys, was using my SII a few hours ago, and I put it down at ~48% battery life. I had it charging off the USB of my PC. I don't have Samsung Kies installed, or anything. I was purely just charging it, on stock rom/bootloaders/no-root.
I went to pick up my phone a few minutes after, and all the sudden the phone won't turn on anymore.
I've tried pulling the battery, I've tried letting it run through any power still in the circuits, by having the battery out for 30+ minutes. I tried the "pull out battery, hold power for 10 seconds, then pop battery back in," to no avail. I've tried download mode, I've tried using my old Captivate jig.. It doesn't seem to be responding if I plug it in(no heat.)
Any ideas? Going to bring it back to the AT&T store tomorrow to try and get a new one.. I really hope they don't give me any ****. -_-;
Update:
I went to the AT&T store today since they just got a new batch in. Unfortunately, my faulty phone actually wasn't a problem with the phone.. It was a problem with the battery.
Somehow, the battery shorted out the entire phone, and killed it. The reason why I suspect this, is that I asked for the old battery in the new phone they were giving me. Sure enough. That phone is now a brick, also..
Thankfully, they were nice enough to give me a different one and not shove the newly dead one down my throat..
So.. Not quite sure how that happens, but sure enough.. That battery is a Galaxy killer.

You got a dud piece of hardware. Shouldn't have any problem exchanging it.

The only thing you didn't mention is using the stock charger to charge the battery for an hour or so. Did you try that? It could be a dead battery. And once the battery is critically low, your PC can't supply enough juice to charge the battery.

Yes, the USB charging mode on the computer sucks. Its easy to draw a deficit of power running off the computer. I had 8 percent and plugged in via USB and within a minute. Or two it was almost dead, fell to 1% in literally 5 mins. It was almost like it was pulling power FROM. The phone
The stock wall charger is 700ma IIRC. Most PCs can output only 500ma max (USB 1.0/2.0 standard). The 700ma is needed when battery level is really low. So, don't leave home without the wall charger.
I tried plugging the phone into the wall charger, to no avail.
Won't even show the charging screen, or get warm.
Bah! Hopefully the AT&T store will have new ones in stock tomorrow.
Bump.

That's surprising - did they confirm that the phones remained dead even with a "good" battery in?
The charger chip in our phones (MAX8922) has plenty of short-circuit protection mechanisms. (Battery prequalification mode limits current to 90 mA at extremely low batt voltage, and it also has temperature limiting.) So a shorted battery shouldn't have been able to damage the phone.

Indeed, we tried swapping the "new" battery into it. Both of the phones were gone. I never even thought it was probable. Maybe it was just a bad batch? Who knows.
Either way! New phone smell, is great. =P
So, my phone's got the standard stock rom, I rooted it, but never flashed it, it has always worked great and hasn't given me any trouble until last night.
I got back from a trip inside my country where it worked great. Then it started running low on battery and shut down.
I went to a friend's house and he had this black berry charger. I pluged it to my phone to charge it and when I tried to turn it on it went on to the "Samsung Galaxy S 2" black and white screen, and started looping on it.
The only "new" "rare" or out of the ordinary thing to it was I had plugged the phone to a blutooth ear piece I bought the day before.
Any ideas?
Has anyone had this same situation?
I looked in the forum, but it seems every loop problem comes out of flashing new roms.
Thanks in advance.
It's possible it could be a battery problem. There have been several threads of boot problems with a fully discharged battery. Sometimes the phone itself can not recharge the battery, and the fix is to use a fully charged other battery, or maybe to buy an external charger for the battery. Not sure if the blackberry charger would have caused a problem. As long as it's a micro usb charger I would think it would be ok.
I have never had a problem like this myself, just reporting some things I have read other people say.
It's likely the voltage is different enough to make the phone unhappy. Can you plug into a PC instead if you don't have access to a "real" charger? It will take forever to charge, but I'll bet it takes care of the boot issue...
Alright so my Vibrant won't charge. I JUST recovered my phone from a brick, (I was having issues with the battery life on Slim Roms 4.0 compared to 3.9--in the middle of flashing back I accidently wiped my internal memory. As I was recovering it using Odin, my fat cat jumped on my bed and caught on my phone cord bricking it.) Flashed using Heimdall and was able to get my phone into working order.
Now, I placed Slim Roms 4.0 back on my phone initially after the unbricking to have something working on it, even though the battery life less than impressed me.
So I charged it like normal yesterday, got it to 100% and was fine and dandy with it working. (Still sucking up battery life like a vampire in a fat camp.)
So the update 4.1 went live yesterday, I flashed it immediately to that. The battery life was amazing! So I do the normal thing when I flash to a new ROM. Let it die completely before charging it completely. It's now dead and will not charge.
Symptoms;
I plugged in my normal cable for work (a cheap cable I purchased off of Ebay.) And up comes the round loading symbol. Followed by a darkening of the screen, followed by nothing.
One thing to note, is while it has it's loading circle on, the bottom buttons light up when I touch them.
My Steps;
-I attempted different USB ports since I charge through my work computer. No luck.
-I "borrowed" my co-workers USB cord and USB to wall plug. Attempted the new cable in the computer first. No luck.
-Plugged the borrowed USB into the wall charger. Same thing happens.
-Used my own cheapy cable in wall charger. Same thing.
-Took co-workers complete set and plugged it in in a different room. Nothing.
-Took out my battery, plugged in USB, placed battery back in. Nothing.
-Hold down the Vibrant buttons to get into Bootloader, it resets the loading circle and nothing more.
So now I'm sitting here wondering what to do. I do not have rubbing alcohol readily available, however since it charged to 100% yesterday I do not believe that is the issue, but I'd be willing to try if I had access.
Something you should know, I am using a Samsung Epic 4G battery in my phone.
-For those who might judge saying it is dumb, I have gotten 54 hours out of that battery on one ROM before, that is with texting, talking on the phone and installing apps. I'm fond of this thing, however I have my stock battery at home still.-
Any suggestions you guys have would be appreciated. I have tried things that I found on this forum and basic tech support to no avail. (I am at work so the things I can use are fairly limited. However cords are of no shortage.)
Alright, I unplugged my phone from being plugged into the wall charger for an hour and 3 minutes later it decides to turn itself on.. Not sure what's going on but I'm not going to complain.
So my question now is, can anyone explain this or help prevent this in the future?
From what I've heard draining a battery until it dies can damage it. But, I'm not an expert on that. It's possible that the battery needed more time to recover from the drain.

Really? I was always told it prolongs battery life. Now I need to research this! Thank you.

I had something similar happen when running lithium volt ROM. My battery completely died and the phone cut off (obviously.) I plugged it in the charger and it immediately tried to boot the phone up but it was bootlooping at the startup screen. I let it sit there for 20 minutes or so thinking maybe it is charging but as soon as i unplug the charger the phone cut off. Luckily I have an extra battery, popped it in, flashed a new ROM thinking that was the problem, turns out it was something to do with the ROM(maybe it needed a certain amount of battery power to boot up). My completely dead battery worked on the cm7 ROM I flashed, plugged in the charger and it booted up normally and started charging.

Oh so it could be ROM related? :/ That makes sense considering I just installed a brand new ROM. Thank you!

Yea it could be ROM related but it also could be a number of other things. Hopefully flashing a new ROM will fix the issue.

Thank you. I might just have to downgrade back to 3.9. It's almost a shame. xD
I'm going to test my old battery in this ROM just to make sure before I downgrade.
You need to use your Samsung usb charger, and wall adapter only. These two are the only ones that will actually work. I had this same problem and realized it was because I wasn't using the Samsung stuff. Even when pugging into the computer, use the Samsung USB cabe only. As for the battery your using... I wouldn't recommend it, no matter the fantastic battery life you must be getting.

Daw it's a fellow Samsung battery.
Thank you about the cable, I need to purchase another one anyways, mine at home seems to not be connecting very well. :/
ROM. some roms do that. it will not let you power up while charging if the battery is very low. you will get the circle and the battery symbol after. sometimes you still cant unless you pull the battery. happened to me many times
Hi guys,
My battery life was getting shorter and shorter. So, I decided to buy me a new battery. I tried the battery and my phone turned on with the green charging battery.
As I turned my phone on when it was filled 100%, my phone gets stuck at the beginning (black screen Samsung galaxy blabla with the yellow triangle)
I thought this was weird so I started it in recovery/download and this does work.
After choosing for reboot I got the omega rom loading GIF, and suddenly I got KERNEL PANIC UPLOAD MODE.
I decided to try a battery from a friend (also Gt-i9100). This battery just worked in his phone so why shouldn't it work with mine.
As I tried it, I first got the message battery too low. But the battery was full in my friends phone. So I tried again, also stuck at the beginning screen.
To make it even more stupid: My friends phone wont boot either after I used his battery.
As I was really tired of this sh*, I decided to put my old stupid battery back in my phone so I could use it for +- 6 hours a charge.
Now my phone is stuck at the beginning with all the 3 batteries.
I tried to re-flash my omega rom, but it's still the same issue.
Is there something going on with my kernel? I thought I could erase the battery stats, but thats not a option in this CWM.
I'm really stressed, because like all of you, I need my phone every day.
Do you guys have any advice, tips or sollutions for my/our problem?
Searching and reading the topics that already discuss the points you made would be a start. :good:
Kill the phone, it's evil.
Regards.
Mark Battery.

Maybe there is something faulty with the battery inferace of the phone or maybe you're just unlucky. I don't understand why your friends phone wouldn't boot after you used the battery - that doesn't make any sense - but either way, I'd order a new battery from a reputable retailer, if it stops working again in a similar way then get the phone fixed/replaced.
My suspicion is that it's either a fault with the phone or that there is something you're not telling us. I can't see how the battery (hardware) could cause your ROM (software) not to work unless the link between the battery and phone is damaged, in which case you need to replace the phone.
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!

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...
