[Q] Phone keeps resetting after startup (Internal memory/battery issue) - Galaxy S II Q&A, Help & Troubleshooting

Hello everyone.
After several hours of googling and going through tons of pages here on xda I decided to make this post.
First, let me explain when the problem started:
The issue
Yestarday I was playing candy crush when suddenly the game started to get "laggy". I didn't think of it, exit the game and left my phone on the table. A few hours later I wanted to use it again only to find the small hard drive icon on the top saying something about Memory almost full. I clicked it and it took me to "All installed programs". I saw that it had used 1.9 gb of the total 2gb and only 20-40 mb were free. I started immediately to uninstall apps that I no longer use to see if this could help. It did for a few seconds but the memory got filled fast again.
This is when I started to search the net for solutions. The first post I read was to delete some log files so i did that. But it didn't change a thing. I thought to myself that I should make a backup of my stuff so it wouldn't go lost if I had to wipe the phone. But before I got to it my phone shut down. Now, when I turned it back on it would just start Media Scan and shortly after shut down. This is where I am now.
I am running stock ROM (have never rooted before).
What I have tried
I found the stock ROM (4.1.2 I think) and I flashed it with Odin thinking this would stop my phone from restarting. It did not.
I have tried to clear cache from Recovery Mode several times with no effect.
I have tried to wipe the phone from Recovery Mode but when I am half way through the setup process of setting up the phone for first use, it shuts down.
My battery also drops in power after the shutdown happens, so in this very moment I am waiting for the battery to charge fully so I can try to calibrate.
Please let me know if you need some additional information and I will happily provide what I can.
Thanks in advance!

You have flash stock and it still shuts down? Hardware problem. Battery old? Try with charger plugged in. Flashing stock makes it like new so there should be no faults. Id say battery is about had it. What firmware did you flash and were from?

My phone (and battery) is almost 1 year old so im still under warrenty if something fails. I just don't want to hand it in and wait weeks to get it back if I can handle it myself
Yes I flashed with stock ROM from samsung-updates.com/device/?id=GT-I9100 so it should be good.
It makes no difference if the charger is plugged or not (which I find odd cause shouldn't it be able to keep awake while on alternating current?).
At the time typing this my phone is online and I am currently backing up photos (yay!!!). What I did was to not type in PIN code so maybe the sim card is the trouble (also 1 year old). I will report back when everything is backed up.
Update:
4 seconds after entering the PIN code the phone shuts down. Also it plays about 10 silent "clicks". Can't hear if its from the phone or from the speaker.
Update2:
Alright so I tried inserting another sim card that I have which has no pin code. The phone boots (but only when plugged) but shuts down after statup, exactly the same place/ after the same time as when I use the other SIM and enter the code.
I have had it online for 5 minutes now without typing the pin so my guess is that it's some setting it loads with the sim that makes it crash (but its a wild guess).
It's also worth noting that it doesen't drop in battery capacity when it shuts down ATM.

Id still say battery problem but could be wrong.

I see some sort of flicker on the screen just before it shuts down. I don't know if this could help someone to address the problem.

For the full memory issue i solved wiping log files in the "/data/log" dir, i had almost 1000 log files, 1 MB each.
Hope this is your problem too.

There is hardly anything left in the /data folder. I have tried to delete the logs (65 mb) from Phone/log but that didn't change a thing. Im going to send the phone to the company i bought it from next week.

Ive recieved a battery that I ordered from china and the phone works now. So the problem was the battery just to let everyone know.

Glad you sorted it.

MicroSD causing high temperature, high battery usage

First off, I tried searching around and couldn't find anything relating to this. I found things relating to high temperatures and abnormal battery usage but found nothing about this being cause by a memory card.
Anyways, since inserting a 4GB SanDisk memory card into my phone the battery gets drained very quickly. What makes this even stranger, when I plug the phone in to charge, the temperature gets very hot (~48C) and the battery doesn't charge. I'm assuming it doesn't charge because of the high temperature.
Since removing the memory card the battery life has returned to normal and the phone charges as it should at normal temperatures.
I'll appreciate any help or tips on how to fix this issue.

I would assume that the SD Card you have is faulty somehow. I would first try another SD Card to see if it also causes the same problem. If it does then it is likely a hardware issue and if it does not then you know it was a faulty card...
Just my opinion... Anyone else have any advice?
Use something like OS monitor to see if the media scanner process or DRM processes is going nuts.
It may be that you have some media on your SD card that the media scanner cant deal with and it causing it to get stuck, try backing up and formatting the card.
Also what rom are you on?
Well this is something, I re-inserted my memory card and now the phone doesn't boot up properly. I tried removing the memory card and it still doesn't boot up properly.
Usually the screen with the 'S' that says Samsung Galaxy S II goes away after a second or two, now it stays for about a minute and doesn't even take me to the home screen. It takes me to the screen that says "To begin touch the android" (the screen you see when you turn the phone on for the first time and asks you to setup a google account) but heres another twist, I can't interact with that screen because in the foreground there are several errors saying Sorry! --- application has stopped please try again and these errors just keep looping.
My rom is stock android 2.3.3

Your best if you don't want to have to format your phone is to use odin to flash your stock rom again (make sure its a non wipe package)
That should leave your user apps/data but you might lose stuff like sms's.

Is your phone brand new? Did you just get it?
I had a Motorola Xoom Tablet that was like that right out of the box and I had to Factory Reset / Wipe the device to fix it.
Follow the advice of the previous poster and try to flash your stock ROM again with Odin and see if that fixed the issue and if not then you will likely have to Factory Reset your device.
If THAT fails then it is off for a warranty repair or to a service center Id assume...

After clicking force close about a hundred times (literally) I managed to get back to the home screen but I've noticed some stuff has changed, See where it says Phone Contacts Messaging Applications in the middle image for me it just says Applications.
Any idea as to whats going on here?
EDIT: I just noticed if I try to open an app, the app crashes instantly.

I've had this phone since July (when it became available in Canada). It worked flawlessly until I decided to put in a memory card a few days ago.
EDIT: And I just tested the memory card in my old phone and it works just fine there.

Droid Razr shuts off on its own

So my wife's razr shut off on its own not even a week after her getting it. So I played around with different chargers till a little white light came on left till morning and nothing. Took it to vzw and they charged it for a few and turned it back on told her to use the cord that came with the razr. The whole time battery was a little more than half full. So today the razr decided to go blank or shut off if you will because it doesn't respond to button presses. Battery was a little less then 3/4 full and laying in bed. No apps installed today since this weekend. Wanted to know if anybody else is having this problem and how it was solved also factory state phone

Soundsike you've got a duff one. Send it back for a replacement
I've never had those problems... If I were you, I would go into recovery, wipe everything, then fastboot the .173. (The data wipe isnt necessary before fastbooting but I would still do it anyway) Before doing that however, I would also take a look at running applications on boot and try to eliminate possibilities. Since you replaced the razr already I would assume the problem had to do with some data somewhere. It could also be worth it to not restore any data from previous backups (Verizon adds things on to backup data and such. When you get ur phone you enter a pin to restore this backup) If you're using a data backup from another phone that could be causing it too. I would also download a battery logging application to make sure somethings not causing terrible battery drains. The best thing I thing would be restoring to an absolutely clean backup with no data and trying that out for a while. Obviously you could have another bad Razr, but I'm more inclined to believe that its a problem with data.

mine the day you received restarted every 5 minutes. take him to warranty, stayed 48 hours. they could not fix and I got a new
do "factory reset" and don't install any apps. if it happens again, you need to exchange the phone
Mine has the same problem. I just saw the last times when it happens.
The phone sends a sound of empty battery, and if you are quick enough, you may hit power button and the lock screen gonna show your batter complete empty, only the red border.
This happened to me:
- Just some minutes after I charged my phone;
- After a factory reset;
- After a fast boot room;
Have no idea when it happens or why. It just happens.
I will send my to warranty as soon as possible.
As far as I know, it is not related with any app or config you do, cause even factory default with no app installed I have got this error :/

AT&T i717 Bad Vibrations (CandyKatt)

Hello XDA,
Way to start off my Friday Hope EVERYONE has a GOOD AND SAFE weekend!
PROBLEM:
Out of the blue it started to reboot itself more often, always had issues with candykatt even after few re-install and wipes. Last night, it would reboot with in 1-5 minutes after full boot and load, then the time decreased to 30 seconds. Till finally 1 second, that is if i am lucky to full boot and load. (auto attempt to reboot with multiple vibrations).Tried to load into odin and twrp, and same symptoms first will fully load into those two for 30 seconds and then auto reboot.
ATTEMPTS
Tried various batteries of various charge types percentages, stock samsung battery fully charged another 2500MAH even 5400MAH. Tried taking sim and memory card out and same thing! (debating on opening up and clean, hope just power button even though feels fine)
CANDYKATT:
I love the rom, work well for couple months with minor popular known issues, like camera not working and random but not frequent freezes. And power hungry, was waiting for updates in forum but never happened. Not as tech savy as i used to be (not my first rom, ran every blackstar and everything from GB, JB,KK and just not on this device) still a not a pro or almost out of noob stafe
XDA FAMILY HELP ME PLEASE!
would love to fix issue with out wipe or reflash at the moment to save files (did not have memory card long)
Phone:

Power Button
XDA World,
Attempt Power Button cleaning and pop out with screw driver (not forced). My button worked fine, looked fine and felt fine. After attempting ODIN and TWRP many times, idk what I did but re flashed and loaded into candykatt os set up. My files still there, and so far has been on for a few minutes as I transfer my photos to SD (full battery).
Uh oh random auto reboot!!! dang it
working better
I still do not know what I did, entered odin and twrp so many times (as mentioned old post). After it reflashed due my button mashing between those two, it works better random reboots even vibrating thing. But does the bad vibrations here n there until I hold power button then reboots.
And was able to sync to get photos off.
I am going to try a new rom, sorry candykatt ...promise soon as bugs are fixed I will re-install
Many times the stuck power button issue seems okay it may not be. I always tell folks to flick the phone in the back a few times, even if the button feels the click. Flick it. Some are courageous enough to take a swab and alcohol to the contacts for cleaning. Not me.

[Q]Galaxy S2 i9100 keeps rebooting on standby

Hello, yesterday I cleared some cache using some app called "App Cache Cleaner - 1 Tap Clean" because my Dad's phone was low on storage, and it cleaned allright and then I umnounted the 2GB SD Card and then rebooted the phone. I don't know if this could be the cause, but ever since I did it the phone always reboots when the phone autolocks (or someone locks it). Sometimes it even reboots and stays black (note when someone calls you don't get a message that the subscriber is offline, it keeps ringing!) and then I have to hold the power button long enough for the phone ro reboot...
I removed the SD Card, tried factory reset, but nothing seems to work. The phone was never rooted or with a different ROM than the officials,. so I honestly have no idea why it keeps rebooting and doing stuff like that. It's on the latest available Android firmware -- 4.1.2.
What can I do to fix it?
Clean battery contacts with isopropyl alcohol, then try replace battery, then replace USB board/port - which is a relatively easy fix to do yourself for around 10 bucks (if you pay someone else to do it, labour could easily take this up to $70/80 or even more depending on labour costs in your country). If you decide to do this, KeithRoss39 has a guide in the General section (search for 'replacing USB charger board') that has all the info you need to get it done.
The other thing you could try before replacing the USB board is to flash stock firmware manually with Odin/in download mode (assuming you haven't already done this/the updates you've done up until now have been via Kies).
If I had to bet money though. I'd be wagering the battery (particularly if it's getting on age-wise) or the USB board (which is a common fault with Samsung phones).
Seriously, that is the only thing to do? I mean, it was okay yesterday and this suddenly hapenned... How can I be sure that it's from the USB Charger Board? And also, the phone won't reboot while I'm using it, but as soon as I lock it and wait a while, it reboots. I just tried wiping the phone again, and it even does that on the setup screen at the beginning... :crying:
Okay, I flashed a stock rom with Odin, as suggested, but it's doing the same thing... Now it's even worse! When I push the lock button when the phone is on, the phone freezes immediately and you can hear the lock sound looping over and over and over again. I have to hold the lock/power button for the phone to reboot... but it does that every time. Even when I don't press the lock/power button, only leave it to lock on its own, it does it again. It charges the battery just fine, I recharged it last night and it has 100% baterry... what could this be?

Battery problems and early shutdown? give this a try!

Hi people, nexus 6P owner since 2 years now. I remember when I received the phone I could reach without worries 5 to 6 hours of Screen but then, after nougat and now Oreo, I've never achieved again that numbers.
After rooting my phone, flashing carbon rom and installing elemental X kernel, I played with governor profiles and improved my SOT a little over this year but it was getting worser and worser by every day (2 to 3 hours of screen on time and heavy idle drain). Finally, the real problem came the other day when for the first time my phone shutdown at 29% suddenly after opening the camera.
So I read internet and found in the nexus 6 (not 6P) forums that someone suggested a solution concerning a problem with how the phone meter the battery remaining, suggesting doing a series of steps of charge discharge that I will list here. This, and changing to ABC rom may have done the trick, as now I'm getting much more normal battery life (considering the degradation of 2 years, 2700mah left approximately) of 4, 4 and a half hours (yours will be better) SoT and an idle drain of less than 0,5% per hour, and apparently it didn't shutdown early anymore.
So, give this steps a try if you tried everything like I did and you still having problems with battery drain.
STEPS THAT MAY SOLVE EARLY SHUTDOWN PROBLEM:
- Charge your phone to 100% and use it until it shutdowns (look at what percentage).
- Boot to recovery by pressing power and vol - button, and once in there let it drain the battery until it shutdowns by itself (may take a lot of time so increase brightness to maximum in the recovery menu under settings to consume it faster).
- Now it has really reached 0% and if you try to power it on it won't let you by blinking red in the notification led.
- Plug the charger and leave the phone off until the battery indicator show it's full.
- Unplug it and turn it on, it should show you the battery at less than 100%, like 95%, 90% or even less depending on how bad it was calibrated (mine showed 95%).
- Plug it to the charger without turning it off until reaching 100% and only then unplug it first and then turn it off quickly.
- Plug it one more time (off) until the icon shows it is full and then unplug it and turn it on, now it should say a number closer than before, like 98% or 99% (mine was 99) or it may be 100%. If it shows 100% then you're good to go with the calibration, but if it shows less, repeat the process by letting charge until 100 and then doing the same steps as before until you turn it on without charging and finally it shows 100% battery.
Please report back if this steps worked for you, because for me I think it made the trick.
Now for the battery drain what I did was this steps,
STEPS THAT MAY STOP THE POST-NOUGAT HEAVY BATTERY DRAIN (android OS drain, etc):
-Unlock and Root the phone
- Install ABC rom (check the post here in XDA)
- Flash ElementalX kernel (also here)
- Install the app "ex kernel manager" from the play store
- Enter settings and disable printers (you still can enable them if you have to print something)
- Install Greenify from the play store and select all the apps that don't use notifications.
- Uninstall unnecessary apps that you don't use anymore.
- In the Ex Kernel manager app go to CPU -> governor options and select "load". Choose one of the following recommended profiles: Excalibur V2, Dragon Fly v1, Butterfly or DeadPool. (Or check the guide in XDA about governor profiles).
- Finally activate the run on boot option and reboot to recovery, wipe dalvik and cache and then boot into system.
If you have luck like me, your phone will run very smooth and battery life will be normal to it's current degradation. My phone now last me all day like before and I don't have to charge it twice or three times like I did and best of all, when I don't use it, it almost don't lose battery (2 to 3% overnight).
Also I've never seen again that android system process consuming the same amount as the screen!
I hope this serve someone and maybe save some phones too , I never resigned my 6p because it's a great phone with one of the best cameras out there even today and with great speakers too.
Please let me know if it worked for you! Of course I don't promise it will, but you have nothing to lose anyway! Good luck.
Pd. Sorry for my English , I'm from Argentina
UPDATE: Today my nexus shutdown at 10% but only because I opened on purpose the camera to check if that is the problem, and aparently it is. I've read that when then phone has low power, an app that consumes a lot of battery like the camera may cause shutdown to prevent the phone damaging internal components. So no fix for that at the moment, just don't use the camera with low percentage.
Hi, I don't know if this thread is still on but I'd like to say that I had the same issue. I have a Nexus 6, as you said, and I've installed on it the Resurrection Remix ROM (Neo version). After that, the phone suddenly shut down everytime it reaches 20 or 30 %. I tried two solutions they suggested me;
1) In bootloader menu, go on bootloader logs and press start button for 10 seconds more or less (when you get Google logo and the phone actually boot)
2) Try to reboot the phone in Safe mode and then back in Normal mode
I've also tried to calibrate again the battery (maybe I did it wrong); I followed a guide on it but I can't remember every step of it (if interested I'll try to find it again). Nothing worked, the phone still presents the same issue and I really don't know what to do. I'd like to try this too hoping it works otherwise the last thing I can do, I guess, try to flash again the ROM. Do you have any suggestions? Thanks so much
P.S.
The battery works PERFECTLY; before I flashed the ROM it worked so damn good so I really can't believe that it needs to be replaced, I know that the phone is really old but it always worked fine so it's more logical presume that the problem is with the flashing
Using Stock Nexus 6 Shamu Kernel, with last TWRP and RR OS
Just replace your battery - you might think it's the flashing etc, but at the end of the day my money is on your battery just having called it day, which they can do quite suddenly.
I found that once that early shut down starts it gets worse quick.
It's not that big of deal to change out on these phones anyway and if you do it yourself it's cheap (15 dollars or so). - I've just done it for the second time, not that I was having early shutdowns with my first replacement but after about 18 months life was starting to wane.
Just sharing my experience with my nexus 6p.
Early shutdown problem sure gives us headache. Already tried several methods like calibration, reflashing to factory images, downgrade to minor build or major build, none of them works.
The only solutions that works for me is replace the battery, only cost between $10 to $20 for me (it depend on type battery that you buy, mine is OEM one)
Hello, giving a try to the OP guide regarding early battery shut down. Just a quick question - how long does it take for battery to drain out while in recovery mode? Screens been on for like 2hours now, I see top right screen corner the battery % completely disappear, but recovery still usable. Just wonder, how long it will take for phone to auto shutdown while in recovery mode?
And if this does not work, I'll just replace battery, like @reintakura wrote above.
This device is a disaster. Does it really work?
I tried this the other day. The phone shut off when the low battery came on. I kept powering it up. The first few times it shut off immediately. The next time it turned on and said I had 10% left. Let that 10% run down, it powered off. I kept powering it on... it would boot. I did this maybe 50 times, every time it would boot and then shut down. Then the last time it got "stuck" on the Shutting Down screen. I let it sit like that for a good 10 minutes. It never powered off, it just was stuck on the shutting down screen. I held the power button down to initiate a hard shut down. Plugged it into the charger, device off. Screen said it was 100% a few hours later. Turned on device, device reported 100% used it until it got to 70% and then the low battery light came on and it powered off. Let it charge overnight with device off. Right now it's slowly losing battery, I'm at 76% and it hasn't shut down.
Strange stuff going on.
i was facing the same problem, two days ago i returned to 8.1 abc rom
i'm getting 4h sot and no early shutdown
I can't believe I spent $200 on this **** phone and waited 3 years to get it thinking its the best thing since fried rice, mine started shutting down at 20-30% now it shuts down anywhere from 30-85%!!!!!!!! ahahahahahaha in the end its my fault for buying refurbished, someone obviously sent this crap back already and they did nothing to fix it and conned me into buying it.

Hi, there. This reply is way late, but I've been away for years and I've only now decided to come back, so I'm necroposting on everything that's relevant to me right now. I hope that's not a serious offense.
I've had my 6P since August 2016. I bought it NOS from Google Fi at a slight discount. It worked like a charm for me for years until around winter 2018/2019, when it started shutting down in the cold. I figured that was understandable. I bike a lot, even in sub-zero temperatures, and I tended to keep my phone in the breast pocket of my windbreaker.
It didn't care too much for that.
So, I started putting it into my backpack and it stopped shutting down.
Then, this summer (2020), the battery went off a cliff. It's been dying anywhere from 80 to 10% since June. Maps and the Camera are the big killers, but the battery will plummet from literally any use.
Yet, it will idle for days if leave it alone.
I recently decided to just wipe the thing back to factory and see if that solved anything. It was quite a feeling to scuttle all of my SMS (I backed them up to my Google account, but it seems like they've gone to some mysterious corner of the Internet from which they cannot be retrieved. Alas). It was kind of a catharsis to throw it all away.
I did back up all my media, however.
The factory reset solved nothing, so I tried the OP's recommendation. I loaded into the bootloader and, instead of waiting on the primary screen, I went into (stock) Recovery (my phone isn't yet rooted) and ran the display test a bunch of times. I alternated between that and selecting "Barcodes" since the all white screen is a bigger drain on the battery than the black and green default.
Eventually, the thing died, but it took hours. This, despite that it would die at the snap of the fingers when in the OS. Strange. I charged the device while off until it said it was full. It came on at 95%. I followed the OP's guide until it turned on at 100.
Yet, it still started draining immediately.
The current culprit is "Mobile Network Standby," which is rich because this phone has no SIM, so why is it even bothering to try and futz with the mobile network? I had been keeping the device on Airplane Mode, but I'd forgotten to turn it back on. I just reactivated that mode, so we'll see if that helps.
However, if I watch a guitar repair video on YouTube (pretty staid, not like gaming or an action movie), the battery just nosedives again.
I don't think that rooting and flashing a new ROM is going to solve this issue.
I bought a replacement battery. I'm just not eager to try and install it. So I may just try root and flash, since it's easier. I guess we'll see what happens.

Then, this summer (2020), the battery went off a cliff. It's been dying anywhere from 80 to 10% since June. Maps and the Camera are the big killers, but the battery will plummet from literally any use.
Yet, it will idle for days if leave it alone.
I recently decided to just wipe the thing back to factory and see if that solved anything. It was quite a feeling to scuttle all of my SMS (I backed them up to my Google account, but it seems like they've gone to some mysterious corner of the Internet from which they cannot be retrieved. Alas). It was kind of a catharsis to throw it all away.
I did back up all my media, however.
The factory reset solved nothing, so I tried the OP's recommendation. I loaded into the bootloader and, instead of waiting on the primary screen, I went into (stock) Recovery (my phone isn't yet rooted) and ran the display test a bunch of times. I alternated between that and selecting "Barcodes" since the all white screen is a bigger drain on the battery than the black and green default.
Eventually, the thing died, but it took hours. This, despite that it would die at the snap of the fingers when in the OS. Strange. I charged the device while off until it said it was full. It came on at 95%. I followed the OP's guide until it turned on at 100.
Yet, it still started draining immediately.
The current culprit is "Mobile Network Standby," which is rich because this phone has no SIM, so why is it even bothering to try and futz with the mobile network? I had been keeping the device on Airplane Mode, but I'd forgotten to turn it back on. I just reactivated that mode, so we'll see if that helps.
However, if I watch a guitar repair video on YouTube (pretty staid, not like gaming or an action movie), the battery just nosedives again.
I don't think that rooting and flashing a new ROM is going to solve this issue.
I bought a replacement battery. I'm just not eager to try and install it. So I may just try root and flash, since it's easier. I guess we'll see what happens.

your battery is probably aged, I got the same problem and replacing battery is the only solution that'll work.

I reckon that you are correct. However, I am noticing that my phone hasn't crashed since I followed the OPs charging guide. That's something, at least.
Although monstrous battery drain is still a huge problem. I will be swapping the battery.
My question is: root first and flash something custom, just to see what happens? For evidence gathering ... in the name of empiricism.
Or just go ahead with the swap before doing anything else?

yeah try root and installing ABC oreo ROM if that doesn't make differ at all then replacing battery is the only solution.
