[Q] i9100 turns off and charge falls! - Galaxy S II Q&A, Help & Troubleshooting

Hello friends. The problem is that, i9100 turns off by itself and immediately falls battery.
I can not find the answer, all threads readed and tried everything.
Tried all official ROMs and wipes. Bought new official samsung battery. Sim On/Egect - no difference. No FlashCard.
Thanks for helping!

Firstly, i can see that you are loosing signal. Put it on 2g mode
Now you need to find out the app which is causing the issue. Install wake lock detector and see what is keep your cpu engaged.
Also, i would advise to dekete the unwanted app data from the internal and external memory.

This two screenshot are: first with sim, second without sim. I havn't installed any apps, only that's going with ROM. Checked CPU and battery usage with programs, nothing wrong....(

I've the same problem since i bought the phone. In my case sometimes it wouldn't even charge and then goes back to work fine.
If you like to see if the problem is exactly the same here is my post http://forum.xda-developers.com/showthread.php?p=46218090#post46218090 and no solution has been found so far.

This is a classic battery failure. Get another battery and it's solved.

thanks, but I bught new battary, same thing...(

I've tried everything, i think it is power chip. Try to buy and re-solder it? Price $10. I will soldering for the first time, so I wanted to rule out other damage.

I Noticed that the phone is not turns off ever while charging. Sorry for the repeat, but how to diagnose hardware failure? Service center samsung do not take the phone for repair, they say that if not approved in this country, the repair will not even for money. If diagnose chip power failure, I can order it and rewire itself. Thanks.

[H] Phone thinks usb/ac is connected/~charging

**Please note, i have already searched this forum and found some similar threads as: charging paused, voltage too high, SGS2 charged all the time, Charging suspended. Voltage too high and Phone keeps charging after plugin off the charger but none of them had exactly my problems so i'll try to describe mine better here.**
Some background and possible cause first
I have been using Omega ROM @ 2.3.5 (yes it's old, but it doesn't matter) for more than 6 months now and i haven't had any problems with it, but a few weeks ago i decided to upgrade to ICS so i did a full backup with CWM and also backed up sdcard to pc. Did a full wipe, formatted sdcard and installed the AOKP ICS, hated the camera app, wiped everything again, installed normal ICS, it was looking ok but i needed my usual apps the second day so i decided to go back to my 2.3.5, restored backup, restored sdcard. I don't remember exactly if i had the phone plugged in before installing ICS or after going back to 2.3.5 but when i disconnected it, it showed that it was still connected and charging...
Please note that everything was ok before updating to ICS (which is one reason why i believe it's software related), i used the original mains charger / micro usb cables at home and i also used a cheap car charger but long before this started happening, and the last time i used the car charger was 2+ moths ago.
The thing is, i don't care if it things it's charging all the time, my problem is that when charging it keeps the cpu active, and even when setting it to 100 MHz the battery only lasts about 5-10 hours with low-moderate usage (see the screenshots of cpu spy, it is clear that the phone does not enter deep sleep while it "thinks" it's charging).
Symptoms
At first, it kept showing it was charging all the time, sometimes when reaching ~10% it went back to normal (YES, normal aka reporting as no plugged in and no charging (=discharging), so i don't think there's any short-circuit/something wrong with the usb connector (which i tried to clean up, as suggested, but the problem is still there) :
---
---
Then (and currently) after 1-2 mins of disconnecting charger/usb cable it stops the charging animation but *#*#4636#*#* and some battery app stats show that it's still plugged in but discharging (also it reports over-voltage, which is weird because when it is still charging it shows health:Good).
Also, if it goes back to normal (aka not charging and not plugged) and i connect the mains charger then disconnect and connect usb cable it will still see/think that the mains charger is still connected and i can't connect the mass storage to pc (the dialog never shows, because it still thinks it's connected to mains) and vice-versa, but the battery is charged no matter where it thinks it's connected.
Now the weird part, and the reason why i don't think it's hardware (aka usb pin short circuit or anything else stated in the other threads) if i remove the battery for long enough (something around 10-12 hours) over night, in the morning the phone would be completely normal (i was able to do this 2 times so far and both times the phone clock&date were resetted which makes me think the "connected" state is stored somewhere in a temporary memory powered by a small battery which keeps track of the time and alarms?; also if the time isn't resetted, the phone would still think it's connected (yes, even after removing the battery for some 8+ hours)), but the problem reappears if i connect charger/usb cable (something to note here, if i connect the cable and it's not plugged in, the problem doesn't start so this excludes micro usb connector problem).
---
And also, as in some other posts, while the phone is shut down it keeps showing the charging animation along with some warning high temperature? triangle:
Here is a screenshot of Battery monitor widget showing some weird voltage spikes, is it possible to reach 5V?
The wakelocks (from Better battery stats app):
Also, something that i've wondered if all S2s do, when i remove the battery and plug in the charger (of any kind) the phone shows a no battery image:
One other thing that might worth mentioning is that sometimes, just a few seconds after i lock the phone, the screen just lights up for a second then turns back off for a few times (2-5 times), but this might be just an app problem and it's not really currently bothering me.
Also i just noticed when posting the screenshots that the battery is always pretty hot, is 32 - 37*C too hot or is it ok?
Conclusion
Well, it's been 3 weeks since this problem has started because i updated to ICS and i still didn't fix it. My plan is to order an Usb jig from ebay, get everything back to stock and send it to warranty, but this will take some 2-3 weeks until i get the jig and another 2-3 until the guys fix/replace it so i'm posting here hoping for some suggestions from more experienced members or people that also had this problem, because i ran out of ideas to try here.
It's a very nicely thorough post, very detailed. I like it.
However, I believe your conclusion that it isn't a hardware issue with the port is a faulty one. I think 100% of the times I've seen issues like this it's an issue with the port that is resolved either by cleaning it, (which will likely only be a temporary solution) or replacing it. It's VERY likely they will do just that (replace the port) if you send it to service. If you can get it covered under warranty, do it. Otherwise the part will run you probably $15 or so, USD.
But the fact that the problem comes and goes away without physical actions and also the fact that everyone started getting this after upgrading to ICS makes me a bit suspicious...

And the fact that anyone who experiences issues like this, when they replace the part, it fixes all these issues?
if it comes and goes, I'd check the port for something when the issue is present. There's likely something lodged in there when it's happening, which gets dislodged when it's NOT happening.
People tend not to protect the port. It can get damaged over time. Also, ICS versions will seem more sensitive to it, because of additional programming and error messages specific to charging and voltage errors added in.

Or ICS screws something up permanently or maybe you're right, and it really is the port, anyway i'll still experiment a while until my jig arrives, if i discover anything i'll update the thread.

I just wish everyone who had an issue that needed help was as thorough as you. Most often, posts in Q&A unfortunately look like: "Halp! My fone broked! Whut happen?!?!"
So while some may scoff at the length of your post, they need to understand; when troubleshooting issues, more than enough information is ALWAYS better than not enough.
Don't worry you're not alone.I'm having this issue for about a week and I don't think that it is a hardware issue because my problem appeared when I was doing a restore from backup from custom rom to stock rom and the only thing that I did is that I pulled off the charger while my phone was doing the restore process. The second thing that I think it is not a hardware issue is that my phone is new I bought it two month ago and the USB jig is so clean, I compared to my brothers phone he has sgs2 too and he's USB jig is full of dust and cockroaches and mushrooms and stuff like that but its working perfect. I'm so sorry that I don't have the answer for you but I'm so mad about this problem that I needed to say something and by the way good luck and pm to me if u find the fix

Please take note.
This is not a hardware problem. This is a Firmware/Backup related problem
Had this exact problem on a friends SGS2 and it kept on happening after he did a restore from Titanium. Not that Titanium is broken BUT your backup stored on your SD has a CRC somewhere. What can I say ... It happens.
Just do a complete wipe and install the Rom you want. DO NOT RESTORE YOUR BACKUP !!!
Install everything again as per normal and set it up and you should be good. If this then still occurs then you can be sure its the hardware but this resolved it for him,

I think it's a bit presumptuous to say it's DEFINITELY not a hardware issue. I've seen a TON of posts where people replace the part for the USB port and the problem disappears.
Maybe for someone its is a hardware problem but my problem appeared during restore from buckup.

Did you discover the source of the problem? I am having the same issue with my sgs2 (only 6 months old). I have all the same symptoms - it tells me the USB is connected and the phone is charging, and I get the same alternating symbols when the phone is off (battery charging/temperature warning). I have done nothing out of the ordinary - no system alterations, all is as it was when I got it, other than apps etc I have downloaded. The port doesn't look that dirty, although having read your posts I am inclined to think that this may be the source of the issue? Any help would be appreciated!
solved
Same issue after upgrade, was searching for days ...
Factory restore, but didn't work.
Forced to stop all services, cleared all cache and cleared Ram and after restart everything back ok. Was not a hw issue.

[HELP] - My GS2 think's it's permanently charging/connected

For a while now I've been having problems with my GS2 and I suspect it's faulty, but I thought someone smarter than I might be able to help. The problem is that it always thinks it's charging, or certainly that it's always connected to a computer. The battery icon in the status bar always shows charging. I've tried at least 5 different roms, including GB, ICS, and JB. They all have the same issue. That leads me to suspect it's HW based.
The main issue is that because it thinks it's connected the battery depletes at an incredible rate. It never enters deep sleep! I've tried multiple Kernels across multiple ROM's and not had much luck. Overnight, without using the phone, it goes from 90% to 10% (this is on RR 3.0.2).
If it is a HW issue, are there any remedies beyond sending it to Samsung? I'm not even sure it's still in warranty.
Thanks in advance.

It shold be HW problem. Have you tried with another battery? If you are in guarante time, you should reflash the stock rom, reset rom counter and back to the dealer
I had the same problem, i tried everithing, roms, kernels, fixing permisions etc.. it can be only fixed by changing the charging slot, i gave my phone to the warranty service and they have done it, it was short sircuit in the charging slot that forced the phone to show that it it charging they said that it is a frequent problem with SGS2 phones. I hope it helped

That's a big help! Thanks. It's good to know I'm not the only one with this issue. A short circuit in the charging slot sounds like it could be the exact problem I'm having. Now I have to find a service centre in London that isn't going to charge me a small fortune to fix it (or I need to find out if I'm in warranty somehow).
Happy to help Youre in warranty till you dont have a yellow triangle and fully stock sammy rom and kernel

Hardware or software glitch?

My brother bought a second hand SGS2 (I9100), and it has some weird glitch affecting the battery reading.
Even though the phone is fully charged, when the phone goes to standby mode (sleep), after a few minutes, or seconds, it suddenly "thinks" that the battery is not charged, so it turns itself off. When you turn it back on, is says we need to charge it, but after 15 to 30 seconds, it reads the battery properly, and goes back to the right battery %. If the phone doesn't go to standby, then the battery glitch doesn't affect, it doesn't say it is not charged, and it can be used with no problems for hours.
I've reset it to factory reset, but it hasn't solve the bug. We have tried also changing for another battery (I have one as well), but is not that, the battery is perfect (both of them). We changed the ROM a couple times, also changed the Kernel and root it, but the issue does not go away.
Can anybody tell me with the info provided if it is a hardware issue (hope not) or if it can be on the software? I've searched the forums but didn't find others with the same issue.
Thanks in advance for any help you can give us to figure it out.

While you're at there, resetting the fuel gauge chip a few times wont hurt either.

After many troubleshooting, the problem was hardware related.

Dont wanna sound rude or anything, but s2 is still not a cheap phone (for most of people atleaset) , meaning,
when ur buying smartphone 2nd hand, the seller will have to agree on me turning on phone, playing with it for 20 mins, check everything and so on..
Display, RAM, everything, meet somewhere where is wireless so you can download android system tester off market etc etc
Because i am almost sure this is HW problem mate. I suggest you call him right away, and hope he still has the same number

Not rude at all! My brother review the phone, but didn't seem to have any issue at the beggining, started to fail like a week later.
We can return the phone at any time, is just that they don't have another one to give us right away, and most likely they'll take it for a review before we can get either a refund or another unit, so we wanted to explore all the options ourselves first.
I'm sure he'll be returning the phone soon as we pretty much ran out of options.

Thanks a lot Jokesy, you have been very helpful as I followed the thread and it is the exact same issue.
After a few days, the problem got even whorse as everytime is even harder to turn it on because it reads low battery. We can only turn it on, most of the time, through Recovery, as the key combination for Download Mode doesn't even respond. Sometimes doesn't respond at all. We just need to turn it on one more time to flash the stock ROM to return it.

[Q] SGS2 screen is black, unresponsive, overheats & drains battery.

Hi
My SGS2 is misbehaving badly. These symptoms occur simultaneously several times a day. I do not know what triggers them or how to prevent them. Your help would be greatly appreciated:
1. Screen goes black.
2. Device becomes unresponsive. The only thing I can do is press the power button for ~10 seconds to reboot.
3. The phone becomes very warm to the touch.
4. The battery drains at an incredible speed.
Might be helpful to know:
Device is rooted, naturally.
Once I've rebooted the phone and I go to Settings > Battery the graph there is showing a black gap followed by a drastic drop in battery level. (See attached diagram and screenshot)
I've noticed that this never happens when the device is plugged in to the charger.
I've recently upgraded to Android 4.1.2 (baseband ver I9100XXLS8) which is the official Samsung ROM after previously running on the Samsung beta version of the same ROM.
Thanks in advance!

Either the battery is faulty or this is some hardware failure. Check if this persists if another battery is inserted.
Also - did the phone get wet recently?

Thank you for the quick response. What you're saying makes some sense to me as I've experienced something odd with the battery a couple of weeks ago. I.e. the battery went completely dead and would not charge, then recovered after a day or two. It did not, however, get wet AFAIK
Might I ask - In buying a new battery, should I insist on an original Samsung make or are non-branded alternatives safe to use?
Kind Regards,

[Q] Galaxy S2 Dying?

Hey XDA!
I'm having an issue with my Galaxy S2 I9100. Basically the problem started a while ago when I dropped it and the screen shattered. I wasn't willing to get the screen replaced so I bought a replacement screen off of eBay and replaced it myself. At first it seemed to be in complete working order and everything was going great. However, over time I got an issue of the phone turning off and me having to restart it. It would come at the most random times too, I would be going about my business and the phone just randomly turned off. The problem progressed and got worse and worse and the shut downs would be more frequent. I remedied the problem by keeping the phone plugged into the A/C adapter and it wouldn't shut down while it was charging. It got worse however, and I could barely turn on the phone without it completely shutting down after a few seconds, and even when it was charging it would still turn off. So basically my question is how can I fix this? Is it a hardware problem and something that I shouldn't try to fix because its not worth it? I tried even resetting the phone to factory settings and everything I had in my knowledge to fix it but nothing would work. Would it be just worth it to sell it as spares? Thanks for helping me out!
That sound like the battery is dying, not the device.

Allright, the battery seems to have expanded a bit as well I should note, so that may be causing the problem. I have a friend with the same phone so I'll try his battery to see if it makes a difference.
Swap it & share the outcome with us.
Sent from the little guy
Battery expansion is a sure sign that the battery needs replacing, and the other symptoms you describe are common to a failed battery too........
If the battery has expanded, that is an indication of a build up of gasses within the cell.....the battery is now pressurised....it could physically fail at any time....best to take it out and throw it away before it leaks fluid all over the inside of your phone. Further charging will only serve to increase the risk of failure.

Oh god I feel so stupid now lol. Yeah I tried it with another battery and the phone works completely fine nothing wrong with it. I guess I'm gonna order a replacement battery off of eBay tonight and sell my phone once it arrives. Thanks so much guys! :good:
Just for future reference however, how is the battery expansion caused and what are some ways to prevent it? Thanks again.
'Old age'. You can't. When the battery begins to expand & feel 'squishy', it's time for a new one.
