Hardware or software glitch? - Galaxy S II Q&A, Help & Troubleshooting

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.

About 2 weeks ago, a guy reported a very similar (probably exact) problem.
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.

Wow! then it is a hardware problem too. Since you said it will be returned, I think it's the last option too.
Good luck and hope you get a normal unit

[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?

Thanks, that makes some sense

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,

Always go genuine.
Anyways you might wanna nuke that device with nuke script.
That all warming thing is just not good.

[HELP]Battery problem Motorola XT912

Hi guys, I have a very big problem regarding to the battery. Sometimes it doesn't charge or maybe it's full charged but It drops from 100%, 50%, 20%, 5% and then die (in a few minutes). Somedays it works well but the average is not good. I tried several roms , full wipes and I changed the battery. I don't know what to do. Any thoughts?
Thanks in advance.
what firmware? that did before the problems started?
I believe your battery is damaged. Possibly from high temperatures. I recommend getting a replacement phone if you still qualify for the manufacturer's one year warranty.
thanks

Flying Jelly 3.01. But the issue is general. Sometimes I plug it in chager mode and shows 100% but when it boots drop to 50% (20, 5, so on) in a matter of seconds.

I already changed it so I think is not a battery issue. I'm trying to avoid send it back because I'm from Argentina and I bought it in China.
Another issue is when you connect it all the night but it doesnt charge. At the first I thought it was a software issue but right now I don't know what to test. I think the most weird is when sometimes works just fine. It's making me crazy...I dont know if send it back or set it on fire lol.
Thanks guys.

Hmm maybe there is something wrong with your actual charging port. Have you tried resetting your phone's software?
I think you should flash the stock. before flashing do wipe. in order to avoid the problem of software.
thanks

I did it several times. I don't know what is happening but since two days is working "fine". The last thing I tried It was die-hard battery script. A guy in another forum recommended me to use compressed air to clean out the ports because it may have a piece of debris that is causing a direct short therefore killing your battery.
Thanks guys.

[Q] i9100 turns off and charge falls!

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.

[Q] Extremely wierd SGS3 Problem

Okay first of all, I've scoured not only XDA but even Google for an answer to this problem to no avail. So if anyone has/knows of any thread that has the answer, please kindly reply or notify me so we can have this thread removed.
Here goes,
I'm experiencing a very unique (afaik) problem with my Galaxy S3. This started a few months back, when the phone started getting random reboots/ freezes and terrible battery life on ANY ROM/Kernel. I've tried CM, SlimBean/Kat, and even Stock and nothing worked. Finally I figured maybe the battery was shot. So a few days ago I went and got a new battery, and that's when it got weird.
I used the latest SlimKat after replacing the battery and after powering on the device, EVERYTHING seems perfect. It's really fast and responsive, battery drain while screen is on is extremely acceptable, things worked like new again. UNTIL I switched off the display, after 5 mins, I pulled out the phone and it was switched off. At first I thought maybe the initial charge wore down so I charged the phone to full, then powered it on. Again, everything went smoothly BUT, after switching off the display for more than 1 minute, the phone shuts off automatically.
I switched to the latest stock 4.3 ROM and restored everything to factory settings and it seems to have helped at first. As usual, everything is fast and battery doesn't drain so much BUT, after putting the phone to sleep, it takes 5-10 seconds for the screen to wake after pressing the power button, and even if it wakes up, it becomes EXTREMELY laggy and often freezes requiring a reboot. As usual, after a fresh reboot, everything becomes awesome again until I have to turn the display off for more than a minute.
I've tried everything, even installing an app that prevents deep sleep but the problem persists. It improved a little after flashing stock rom and reverting everything back so I'm really hoping this isn't a hardware issue. Is there maybe something else I can try, settings/software-wise? The phone is almost 2 years old and is already out of warranty.
I'm hoping it's not the sleep of death thing because the phone isn't exactly bricked. I can still use it for as long as it doesnt have to go into deep sleep (I turn it off before putting in my pocket and turn it on again when I need to browse/use the camera which is all it's good for in its current state.)
Also, the symptoms don't really fit the usual "Sleep of Death/Brickbug" Symptoms I've read about.
Hey, I remember having a similar problem. I formatted both my internal sd and external sd. Haven't had any problems ever since. Hope this helps.

Already tried that. I did full wipes/formats on all my installs. I even tried not having an external SD inserted for the Odin installs. I tried not installing any app on the phone and it still gets messed up after going to sleep. As fresh installed AOSP or Pure Stock ROM. Odin flashes no problem so I'm really hoping nothing hardware-wise is messed up. I had to re-flash PIT after getting a new battery though, could I have messed something up there that would lead to this?
There is an app for that deep sleep syndrome, it's on playstore its calles brick check or something like that, if you cant find just google it.
And I dont think that could be software problem, BUT depends on what apps you used, flashes you made.
Hope it hepls
Well, i don't think its deith break, but i had the same essue with unofficial 4.3 and then at official 4.3 it worked well,
it may be a break in the motherboard or something.. as u tried every rome avilable it couldn't be softwear thing..
the app for emmc firmware is called 'eMMC check', you can find it on playstore
edit: does your phone heat up? or battery? did your display ever turned blue when waking up from sleep?
it could be also a short with your display/motherboard or other connectors or battery connector... and the protection kicks in
if you're good with tools and phone is not under warranty, you could disassemble it and reassemble/reseat the connectors
or, could be the power button shorting, if you decide to open it, examine the power button
@Eibram did you ever undervolt or overclock when using custom kernels or roms? Because it could be hardware damage.
Also, do as they tell you above, check if you have the insane f01 emmc chip. I know it's a common missconception going around that since 4.1.2 the SDS got fixed, but it didn't really get fixed since it's a firmware problem in the emmc patched through software which just makes it highly unlikely to happen (but not impossible).
I did some minor undervolting way back before JB came out but not since over half a year ago. I did the eMMc check and yes, I do have the inane chip.
Just an update, I re-flashed a PIT file and a rescue firmware and it seems to have helped a bit. It was running fine for over 12 hours aside from a random reboot just now.
I'm observing the phone right now to see wether the reboot was just coincidental. I really wish this is just a software thing.
Okay one more update, 2 days in and I've only experienced the one random reboot. It's still sometimes slow when waking up, but something around 2-5 secs sore not 5-15 seconds slow. I'm thinking that must be due to touchwiz bloat.

My tablet turns off by itself

Good evening. As the title says, my SM-T820 turns off randomly. I've changed the battery and installed several official firmwares with no luck so I don't know what else I could try, if anybody has any idea please tell me.
Thank you so much
Kind regards.
I've had similar problem after trying different firmwares.
My solution was to go back to stock wiping everything there is.unfortunately I cannot really remember my steps, just be careful not to break anything, find a guide for this.
All I remember is doing some painful steps with Odin.
Thank you, I'll keep trying, if it's not broken by now I'm sure I'll not break it...
Regards
Mine also keep restarting by its own .. and freezing and turning off .. then I can turn it on without a hard reset ..
I found that power saver mode makes it longing till it restarts again.
Did you find a solution ?
I also had this problem. Mine was overheating heavily and restarting, then again overheating and so on. My way to fix it was to send it to Samsung Service, and unfortunately they said that they can no longer fix the device since parts are not available. So I asked them if they will exchange motherboard if I supply one, and they agreed but offered no warranty for such replacement. I got motherboard from aliexpress and my tablet started working as it should from the begining. The other issue I had with "old" motherboard was really high battery drain even when tablet was not used. It lasted like 2 days without use, now i'm charging it approx once a week.
