My Samsung Galaxy S2 is ded - Galaxy S II General

Hi,
I was right in the middle of a meeting, my SGS2 was on the table and it kept flashing for apparently no reason! By flashing I mean going from sleep mode (dark screen) to lock screen. There was non incoming call or messages, no running application. So, as this was weird to me and it was disturbing every one, I tough it could stop doing this if I restarted it. I made a long press of the on/of key thinking it would reset the system! Since this time the phone turns off to never wake up! Is there something I can do to have it back to life?
Thank you for your help!

When I got home I connected it to the computer, I've wait some times as nothing happened I took it to press the power buton but, it was so hot that I had to drop it to avoid burning! I unpluged it, I put a fan on if and, I removed the battery! after a while I replace the battery and plug it back to the computer, the same thing happend! actually it is pluged to a wall outlet for about half an hour, it's not hot, just a little bit but, stil there,s no sign of life!

BRO!!! SAME AS MEEEEE!! (similar i guess)
In the night after i flash miui v4 and neak kernel v2.0.6 (its old..) i plugged in the power and went to sleep. Next morning when i took my phone for my morning news THE PHONE WAS HOTTTTTT (very!) Ok..... i did the usual and checked my cpuspy mostly was 500mhz and 200 mhz NO DEEPSLEEP! dafuq? Ok reason found... So i guessed it was the kernel issue and so i flash a newer neak kernel. From there i went to school. Once there i checked my phone and it was warm.... cpuspy states decent deepsleep so i guess its just me but after awhile it got hot again! so i gave in and flash siyah 3.3.2 (used neak in the first place as some games wont work on siyah)(after initial boot from the new kernel there was major batt drain!!! From unplug to me flashing the newer neak kernel i already lost 60% batt wts??!? But after flashing siyah kernel i was left with 14% batt from 40%.... ok never mind i will just UV UC and other power saving stuff which helped a lot on previous days. Those "did" help and yeah all was cool till about 6% when the phone (you can guess right?) got hot.... HOT! So i gave in and powered down the phone..... i pulled the batt and separated the two for awhile. After the main body cooled i replaced the batt and rebooted the phone. After booting the batt was at 4% after seeing the batt level i powered the phone down and left it that way. Not even 1hr later the phone refused to boot.... no buzz no light no screens no nothing! I had to wait a few hours before getting home from school (omg yes it all happened in school zzomg ) now im at home with my charger and all (a different charger this time made sure it worked first) and no matter how i try to boot the phone plugged in with and with out the batt it refused!?!!?! WTS IS THIS BS?!?!
Sorry for the vulgarities and caps peeps...

I know nothing about Android, I'm new to this platform, my first smartphone was the N8, it has been stole, after I had an iPhone 3g I change for galaxy cause it was cheaper than iPhone 4 or 4s, andt it's a beautifull piece of hardware but, for all the rest I was disapointed and I've never liked it so much! I think I'm going to return to samsung to have an other one and when his back, I'm gonna sell it!

I think your usb/charger port is broken.. that is what happend to me. Try to charge the battery with an external charger to see if it turns on. Then get your phone to default (unroot/stock fw) if its working and let it repair. For me it just took 2 hours an i had my phone back for free.

Mine was fixed by getting a new battery but now it died of the same reason (something wrong inside with the boards i think) sammy better get me a new one

[Q] Phone Turned Off By Itself (Red LED flash)

So I just beat DeadSpace (yay), then I decided to reply on a harder difficulty. Within 15 minutes the phone turned itself off and the LED flashed RED once really briefly. Now it won't power on at all. The issue just happened, I don't know what's up.
I hope it isn't in the untouchable state (soft-bricked) again...................... Of course this stuff happens to me at this time in the night when nobody is awake to respone ......... What do I do? How can I fix it?
If it fixes itself I'll let you know.... I know for sure that I'm not playing Deadspace again after this...
EDIT 1* Just unplugged the charger and popped it into another wall. Now the Red Flash is just staying on, the phone is plugged in. What's going on?.......
EDIT 2* The Red LED stopped, phone still won't power on
EDIT 3* The phone now shows the low battery screen while being powered off... I'm guessing it'll power on now
EDIT 4* The phone successfully powered on, nothing is wrong with it now
Sorry for posting this thread it seems like a waste now..
Soooo! To make it not so pointless, I think I found out why it does this. I think Deadspace drained more battery than the phone could charge so the phone died (battery drain) with no warning. And when it did die the phone was in a state of "what the heck - - - computing - - - enjoy this RED LED!!!!!!". I guess it just means "Super dead battery". So in case anybody else fears for their $500 investment, just give it 10-15 minutes before you panic, and let your phones actually charge
From what I can gather from the various threads about the "Red Led Of Death" is that if it's flashing - it's recoverable in some way, if it's just a solid glow you're SOL. I've spent the last 2 days trying to get my N4 to live again Would actually help if people where more specific about if it's flashing or not.
Just got off the phone to the Play Store and arranging for them to start the RMA process. I guess I'll find out in a couple of weeks what the problem is.
When I first rooted I had the light for 4 hours, got it in and out of the red LED state 3 times that night. It was a horrifying experience. I do not know how I fixed it. I was jamming buttons and eventually got into the boot loader mode, from there I flashed stock boot.img and the rest is history... I wish you luck!!!

Nexus 4 Shuts Down Randomly and Battery Problem

Help people, I have the nexus 4 for over 3 weeks and great but a few days ago when it was nearly full battery (around 80% or so) suddenly shutted down and I couldn't turn it back on until after 1 min or so plugging in. I did not care about it the first time ... But today, after having it charging about 2 or 3 hours I disconnected the cable to use the phone and the battery dropped from 90%+ to 8%, so I connected the cable and put it back to 100%, used it for 1 hour and it suddenly dropped back to 2% from 80% and then shutted down instantly.
Here are some screens.
Help please, and yes I have used the search function, but didn't find the solution on other posts.

What apps have you installed lately, maybe there is a rogue one. Install BetterBatteryStats for app behaviour and Cpu Spy for deep sleep issues.
Are you rooted? Custom rom or kernel? Undervolted or overclocked?

I'm not rooted, all at stock. I didn't touch the voltages, I didn't do anything. I installed some games (vector, pudding thd, order and chaos) evernote, mega manager, pulwifi.

Also I attached a pic of the cpuspy, I can't install betterbatterystats because it costs 2 dollars

I see nothing abnormal on usage, just use the phone and see if this behaviour continues. If it does better do a factory reset or reflash the latest factory image.

Okay I'll uninstall the latest apps I installed and will use the phone normally, if this happens again I'll do a factory reset and if the problem continues I'll call google. Thank you :good:
I wish I could be more help but I had the exact same issue. I could not figure out what was wrong with it but I had previously broken the screen and sent my N4 back to LG for repair. Since it was still under limited warrenty from that repair I sent it back to them again. They said they replaced the charger connector. I got it back and it seems to work fine now.
My issue started after I updated to 4.2.2 I believe. I don't know the root of it but my advice would be to do what you said and call Google or LG.

Similar issue here - I've been using the same apps since I first installed them after N4 purchase (meaning no new apps/games installed in the last few days and no settings changed). Took a nap for a couple of hours and woke up to see N4 completely dead - 0% batt. Charging it now and looking at partial wakelocks etc, havn't seen anything out of the ordinary. Hopefully it doesn't occur again but in the meantime still looking for a reason why this would suddenly happen.
Are you guys using the stock chargers? And charging through mains?

Yeah, am on stock JB 4.2.2, unlocked and rooted though, no other change like new roms flashed or anything. I use the stock charger and charge through mains.
I think there have been a few threads with this issue and nexus4s even prior to 4.2.2 and supposedly it was hardware. I called support while talking it through she had heard a few similar cases and it seems to be a hardware/software design issue. My wonder is how can I enforce 'never deep sleep' because my kernel doesn't seem obey.
I woke up this morning with the indicator light on but phone dead requiring reset (charged though - if not overly so). Just now it died again while sitting on my desk at 80% charge and deep sleeping again.

I've read in a few places today the stock charger has been causing a lot of the charging issues and plan to switch to my old g2's charger tonight
Just RMA'd my nexus for powering off for no reason - would do it a few times a week (and extremely buzzing earpiece - which I was living with), never had a problem putting it back on though or had issues by battery levels being eratic) did quite a bit of testing over the space of a few weeks and found it continued to do it after wiping/fomatting everything and on Stock 4.2.2 non rooted and locked BL. As far as I am concerned if its still doing it with the stock out of the box set up its a hardware fault.

Dunno about that its up to you mine was doing it 2-3 times per week. I would wipe everything including userdata, reflash stock rom and monitor before going through the rigmorole of the RMA to make sure its deffo a hardware fault. Biggest problem with the RMA is the fact they put a hold on your credit/debit card for the price of the phone. So basically if you don't have the funds available you are shafted (I think you would have to send off to LG in that case).
I got the same problem ..just that my n4 back cracked while was charging :-\
maybe you should try to flash other kernel and rom if you cant solve this issus. if your N4 is unrooted then just bring it to LG store, you got warranty rite ?

My Nexus 7 is doomed...

A few weeks ago, i flashed a stock rom on my wifi nexus. I was happy with it until last week. Charging became incredibly slow - 30% over 8 hours. I threw it in my bag and wheb i got home 8 hours later, the battery was depleted completely. I couldn't turn it on. I plugged it in over night and it stayed at zero percent. I booted into recovery and reflashed my stock rom abd wiped my data. Still didn't charge. I tried going into my bootloader and hitting power off and then plugging in, but it still wouldn't charge. I can't flash my backup because it's on my card that i lost, and even if i had it, i wouldn't be able to keep it on long enough to flash it. ADB won't run on my pc and i don't know how to use the program anyway. What can i do to save my device? Please help.....

Not the average flasher knows how to tear apart a device - including myself. Anyways, this thing won't power up at all? You tried leaving it plugged in and booted into bootloader? If so, sounds like a hardware issue or the battery is defective.
I would be willing to bet that your battery connection came loose. Start at your USB port with a thin piece of plastic, such as a guitar pic. Work your way around the device and remove the back.

I heard that was a good site. I'm more scared of screwing up any hardware than doing the actually tearing apart.
I can boot for like 30 seconds and then it shuts off. I've tried the solutions in the thread link above; however, i still think it is a software issue. I've used other roms that had really slow charging, but i was able to switch to another one before the battery got depleted. So i think my best bet is to somehow get a new rom on my device somehow. ADB won't run on my computer. It just flashes a command prompt on the screen for like half a second and closes.

What kernel are you on? The kernel is what does the charging operations.

I had a similar situation in that after the battery died, I got it to the point where I could boot up, but after a screen timeout, it would be dead again. Finally, I got it booted again (while plugged into power) and immediately went to developer options and checked the Stay Awake, never sleep while charging. Keeping the screen awake kept the N7 on and it charged up.
Funny my Galaxy Nexus started doing this crap on me too after I updated the rom and kernel. The phone and battery are only 2 months old replaced in April.
Occasionally it won't take a charge. I have to **** with the battery, removing it several times. Then all of a sudden it starts charging again after 10-15 resets.
Haven't had a problem in a while. Typically hits me like every 2 weeks.
No problem on N7 though but it happens. First thing is to change your kernel and rom to something else. If still draining, flash stock and relock, unlock, relock, wipe. Boot, upgrade to 4.2.2 and test.

[Q] How to fix strange battery behavior?

Since last week I am experiencing a really strange behavior of my battery.
Sometimes my phone (in a random app) just vibrates, the screen goes black and then it reboots. After the reboot I have lost 40-50% battery life. Sometimes the phones isn't even able to complete the reboot because it spontaneously has too little power left. See attached screenshots.
Has anybody had similar problems? Or knows a solution?
About my setup: The problem seems to be not rom or kernel related. It occurs no matter what rom or kernel setting I am using. Currently I am running coool boy's 4.3 GE witch KT's kernel (no OC or UV).
Is it possible that the battery is physically damaged? I have NO IDEA...
Experiencing the same problem. I've flashed back to stock and still experiencing this. Phone randomly turning off, not starting, sudden battery drops. Driving me crazy.

I've seen the same sort of graph on my old i9000. You're not gonna like this, but it got worse over time, and eventually my battery wouldn't last more than 5 mins. I thought buying a new battery would help, but it didn't. When I sent it in to Samsung they said they would have to replace the entire motherboard...
I think it's got something to do with the motherboard not being able to correctly sense the battery voltage/whatever/%. The phone reboots automatically because it thinks the battery is flat (even though it isn't).
If you're under warranty I suggest sending it in soon... Hopefully it's not the same as what I had heh.

Well *#!$
I'll observate it for the next few days and see if it's getting worse...
If your phone is rebooting as opposed to just powering off, then I suspect it is hardware related (motherboard) as already mentioned.
I do hope I'm wrong though.
Maybe try using it for extended periods while plugged into a charger and see what happens. If it doesn't reboot then it may just be the battery.
Right as OP I'm suffering the same exact problem or there abouts. I've flashed back to stock rom, fully charged to 100% drained to 0% back to 100% yet still phone keeps shutting off randomly and the only way it works properly is with the charger plugged in. It's escalated quite badly with now after a few mins of YouTube turning itself off and not rebooting. I've requested a repair by o2 who I'm in contract with and see what will happen. I've heard crap stories about their repairs before taking it to Samsung.
I9500 owner. Had this exact same problem when using older firmware. After updating to the latest one, never had this issue again. Its been two months now, even more.
Try this. Flash the latest available firmware for you phone, not talking about OTA but the downloadable one from any region (whichever is latest for i9505). I guess it may have something to do with the kernel too.
Edit: wait a minute, why is your battery level going up when it isn't even charging in the second screenshot. Middle of the battery timeline. That's weird. I guess you should send the phone back

In the last few days the problem occurred more often. But now it is just shutting down (no reboot after vibrate) and after plugging it to the charger and restarting it sometimes I haven't lost any battery. Strange!
I fear there is nothing else to do than turning it in (warranty)

Same problem here. It started three days ago and today I'm barely able to use it... I'm still on warraty and I even have insurance, but it's a major inconvenience anyway.
Mines gone in for repair back to my carrier still no movement despite them having it for 2 days now really should have sent it back to Samsung directly. Will keep you guys posted.

I've flashed back to stock rom, fully charged to 100% drained to 0% back to 100% yet still phone keeps shutting off randomly and the only way it works properly is with the charger plugged in. It's escalated quite badly with now after a few mins of YouTube turning itself off and not rebooting. I've requested a repair by o2 who I'm in contract with and see what will happen. I've heard crap stories about their repairs before taking it to Samsung.

Hey
I am new here.
but i was looking for information becuase my s4 9505i has the same problem
shuts of almost everytime i open apps too quickly or stream youtube or some other high usage apps etc.
battery drops up to 50 percent then back 40 percent then to 0 percent, the fact it that the phone never seems to know where the battery is.
by the way my phone is not rooted and i have done the factory reset a few times.
samsung... hmmm.. they seem to be real hard to talk to on the phone, i have had to call them 4 times already about the s4 i ahve had since june, and they just play me off like i am some kind of idiot etc. and deny that there is possibly any reason for random shutdowns, phone freezing, and now this battery/motherboard issue.
next bit is kinda stupid, the phone has a few internal scratches on it from when i ahve stupidly had the phone next to keys and all that. im sure they are going to try and void my warranty and say i have mistreated the phone...
had many phones before, maybe close to 50 and never, never, never have had to ring up a company to try and complain etc.....
any ideas.
I am in Australia,
I am thinking of trying the CONSUMER AFFAIRS kind of threats, but i have to word it the right way...

Flashing red light of Death!

Hey xda'ers my nexus 4 just crapped out with the flashing red light of death. I've read it's just a dead battery and I should let it charge overnight. My situation was I am currently using slim bean 4.3 and was flashing between kernels, went from faux to semaphore to hells core and on hells I ran antutu and after that my phone went into a coma. I had a full battery when flashing so I'm at a loss as to why the flashing indicates a deader than dead battery. Any help appreciated.

Try this before anything else:
Plug in the factory charger to the wall and to your device for 1 minute. Wait to see if a battery charging symbol appears on screen. If it does then press and hold the power button for at least 15 seconds. If the aforementioned battery icon doesn't appear then plug your device in again but this time for one hour. After one hour of charging disconnect the cable then quickly reconnect it after waiting one second. Press and hold the power button for 15 seconds. The device should power on, if not repeat the last sequence of steps but substitute the one hour of charging with 10hrs of charging (overnight).
I hope it works for you, Report back and give an update!

Thanks dude I'll give it a try. I did see the battery icon with the charge symbol in it for a second when I plugged it in. I'll follow your steps and see where that gets me. And really, can the battery suddenly just drain like that? I mean I had 98% or more. I think I have a haunted phone. Thanks again.

Edit: ok just tried powering it on and I got to the Google boot screen then death again. I'll let it sit overnight then try again. Thanks for the guidance Sir.

While its very strange and very uncommon, it can happen. It could be the result of something seemingly unrelated too, its hard to say. I've had it happen to me once with another device. Good luck with the charging though! I'm more than happy to help

If it's boots up with 0% battery I think that you should try to use another battery and to see if it was a battery problem.

Oops..Yes my bad, so take it to service center and tell them to change your battery.
Well I let it sit overnight charging and the red light still flashing. I can get the phone to Google boot screen then nothing. Screen goes black and back to the flashing. I can't get onto fastboot mode or recovery mode to flash to stock no button combos work. So I guess either I send it back to LG or maybe send it to josh(conexxion2005 on xda) and see if he can help. Thanks guys for all the help guys but I think I'm dead in the water. I do have a tiny T6 torx for my Oakley sunglasses I think will work on the phone I'm tempted to take it apart myself to look at things.

The last thing you can do [and the only which fix this kind of problem] is turn off device, open the back case [2 screws], remove the battery flex cable and put it back.
Now try...before you RMA it.

I'm gonna try that but now I just realised that my T6 torx isn't small enough to get the screw's out. I'll take it to work and try to mess with it there. Seeing as my device is rooted and various other they'll surely not warranty it. But I'll try not to @#$% it up any further.

Hallelujah!! My phone lives! I took the thing apart and took of the battery connector and placed it back and wham!! Back in business! Thanks guys for all your help.

I wouldnt worry about rooting etc with regard to warranty. You can return in to stock in about 5 minutes with fastboot

Correct, but if I can't enter fastboot mode or recovery doesn't that limit my options to returning to stock?

From what I understand, as the battery is well- cheap and crap if you run a benchmark and the system draws a lot of power it can knock itself out due to the voltages or something.
