Weird battery bugs.

Ever since I flashed Arconium ICS 4.0 and KTG kernel, I've been facing extreme battery drains. I fixed these drains by flashing the stock kernel but now the problem is, instead of properly shutting down when the battery is empty, the phone keeps rebooting itself. :/ I tried everything. I even flashed .62 firmware and then doomkernel v22 and arconium 8.2. But I'm still getting these reboots at empty battery. Any help ?
I'd also like to know if anyone uses 1.8 Ghz or above in GB with stability and NO crashes. Even with Antutu benchmark. I used to use 1.8 Ghz before without any problems but now it crashes randomly. :|

Anyone. Please ? I'm getting these problems in stock .431 too. Especially the reboots at 0%. v _v

i had once a problem like this and i flashed .42 and stock and it helped
but it can be that your battery is demaged
or try to flash .42 with stock relock bl and than repair via seus maybe that helps you
sorry for my english

Tried EVERYTHING. :/ Still phone keeps rebooting at 1% or 0% battery instead of shutting down. Really annoying bug. Someone please help.

Arc S random reboots

My Arc S randomly reboots itself, some 2-5 times per day.
I have unlocked bootloader, tried 3 custom kernels (ArcKnight, stock 4.1.A.0.562 and stock 4.1.B.0.431 with CWM) each with 3 different roms (JJ hybrid, Arconium ICS and Mooded ICS 90.3) and still the same thing. Does anyone know if it's kernel issue, software issue or something else?
Only thing I haven't changed from my stock rom is the baseband (64).
Any chance it's hardware problem?

well maybe the battery would have been loose enough to connect and disconnect from the phone

Completely flash back to stock using pcc repair, that's probably the best idea for the moment if you still get it, then try and figure out when it happens I.e. is it when the phones hot, when your jumping around or completely random.

Turn off your phone, take out the battery put it back in and boot the phone
but make sure you've charged the phone to about 50% atleast

i took off the back cover and shook the phone violently, it doesn't reboot so i guess it's not the battery connection.

it reboots completely random, sometimes when sitting on the desk, sometimes in the middle of conversation...the heat is normal for the usage situation (no heat when not using the phone). have to see how to use pcc repair, since i haven't used it. i have stock backup made from CWM recovery after unlocking the bootloader and flashing new kernel. maybe i can restore that backup?

undervolting? governor? i even dunno what those things are I just flashed the kernels that i listed above and used them as they are. i had the same problem with all of them, except when i think a bit, i didn't have problems from the very start. there were some rom versions maybe with combination of the apps that i was using at that time that didnt make my phone reboot. i just dont remember which roms and versions they were

Same issue here
Any result yet lalek?
I'm running Mooded ICS 90.7 on my Arc S, with DoomKernel 2.6.32.9, baseband 72, unlocked bootloader and rooted (obviously), and over the past week or so it's been doing random reboots. Sometimes twice a day, sometimes it will go for a few days.
Apps are Titanium Backup, Link2SD, AVG free, Dolphin HD, Superuser, MX Player, and just the usual banking apps, Angry Birds, Gmail etc. It's only rebooted while sitting on the desk sleeping, never while in use. I've uninstalled apps, found it still random reboots so reinstalled them. I'm starting to think its ROM or kernel related.

You should try re-flashing stock ROM ftf file using Flashtool, I recommend 0.587, see link on my signature for ftf file.
Try that for a few days, I'm sure it will be stable, then you can further customize the ROM.
Also be careful of heat if using some sort of tight-fitting case with the phone.

Thanks
I'll try that tonight!
I do have one of those TPU cases and had the phone pretty hot gaming while charging, but it's never hot when it does the reboot.

It will happen when RAM eaten by running application in background. Uninstalling a few apps will be help.

My wife had same problem, started on stock rom, then i tried root and other roms, stil restarted as it whanted. Peace of paper made little help- from 5-8 restarts per day got 2-3 per day. Had put back stock rom stil once in a while just restart it self. Women stuff- ip webcam to look out of sleeping kid, FB, gmail, web and thats all. Strange

hi guys,
same problem here on my Xperia Arc
i have worked out what is causing the issue for me.
i ran a logcat that updated live to a file on my sd card so as soon as the device rebooted, it had logged the very last thing that happened on the device.
turns out the last thing happening was WiFi scanning.
i then turned my WiFi off and for the past 3 days i have not experienced a reboot at all!
when this first happened these are the steps i took.
i completely wiped the device (factory reset, wipe dalvik cache, wipe cache partition, format system)
i then flashed Baseband 77 using flashtool
i then flashed fxp149 using flashtool
i then flashed Baseband 77 libs using CWM
i then flashed AOKP JB M1-R1 ROM using CWM
i then flashed gapps using CWM
i the reloaded all apps from the market and not applied any backups and yet it still rebooted all the time.
Since then i have tried using
Fusion 3.8
Fusion 3.9
Fusion 4.0
FXP 148
FXP 150
Stock Kernel inside ROM .zip file.
I have also tried putting it back to Baseband 72 but it made no difference.
I then decided to go all the way back to stock firmware as it is out of the box.
so I used flashtool and flashed LT18i_4.1.B.0.587_(1254-2716).ftf
I reloaded my applications and monitored the device only to see that by the next day, the problem had returned.
THIS IS NOT A ROM OR KERNEL ISSUE!!
or at least it isnt for me, but it sounds EXACTLY the same as what everyone here is experiencing
i advise everyone, no matter what ROM or Kernel you are running to try turning off your wifi or even putting the device in airplane mode for a day and monitor
also try running a live logcat
to do this, open a terminal session and type
su
cd sdcard
logcat >> logcat.txt
then leave the terminal running in the background. (you will have the icon in the notification area that tells you its running)
you can then check your sd card and will see logcat.txt file there
you need to open it in wordpad or something of the sort as notepad doesnt display it nicely enough to read
anyone who tries this i would love to hear how it goes
i am curious to see exactly what is causing this but im starting to think it is a hardware issue.
hope this helps!!

[Q] Xperia S freezes randomly

Hi everyone.
I'm having a little problem with my Xperia S, it's kind of new (2 weeks of use).
When I'm using normally the cellphone, everything works great, but if don't use it for a long time and I grab it faster and unlocked it, sometimes the cellphone freezes! Well, not exactly freezing, it still works but VERY slowly, almost like freezing. I can't turn it off with power button, I had to user Power + Volume button to turn it off/restart it.
That happened in first week, so I unlocked bootloader and flash it another kernel (advanced stock kernel), and the problem was there.
Later I made a backup of the firmware (I updated to its last version with PC Companion, ICS btw) and flashed a custom ROM (XTXperience 4), and the problem was still there.
Yesterday I flashed a Generic ICS ROM downloaded from XDA Server using Flashtool, everything went normal until today, when the problem happened again.
I've been searching here in XDA and Google and still nothing seems clear of what is causing the problem, if it's the sim card or maybe a hardware problem. I'm going to relock the bootloader today, and I will try to repair the phone using SUS.
What is causing the cellphone to freeze? Hope someone help me with this. Thanks in advance!
btw, sorry about my english, hope you understand most of what I wrote

Well in my experience,
The phone freezes because it is too hot,
Or the RAM memory suddenly drops.
I mean sudden ur phone's RAM memory is 0.
I'm not sure too.
But I think reflashing the kernel, or flash other kernel will fix the problem
Try it

What ics firmware did you flash? And did you do a complete wipe when flashing?
Sent from my Jellybean Xperia S

I've flashed other kernel and yes, I do a complete wipe when I flash another ROM, via Flashtool or CWM.
I've been thinking of rolling back to GB to see what happens.
Yesterday my phone freezes like 2 or 3 times in less than 15 minutes. First time I reboot the phone and it was ok like 5 minutes, then it freezes. I reboot again the phone and happened again.
Its not even hot or using a lot of RAM, it always has like 250 or 200mb free

Did u play with CPU settings?

No, this is happening since the first boot of the phone. When I turned it on the first time it happened, and I had to search how to force a reboot because I didn't know how to do it LOL
It doesn't happen very often, but when it does is very frustrating!

Try flashing a new rom, but wipe the system partition too? I always do that to ensure a fully clean install.

I'm thinking in flashing a non based stock rom, like CM or MIUI, because I flashed XTXperience before and the freezing happened.
Oh, and the problem still exists. I believe Wi-Fi connection maybe it's the problem, I'm testing some things right now.

Had this too using Supercharger (by zep) but after few setting it's gone. Maybe you should try to run the script ?
It was with stock rom and advanced kernel v15/16.L

Well, I was on 6.1.A.2.45, I relocked the bootloader and an update changed the firmware to 6.1.A.2.55 using SUS without wiping data and the problem was still there, so I repaired the phone with SUS, it erased everything and the problem was gone for like 2 days. Today it happened again.

Advanced Stock Kernel supports 6.1.A.2.55 firmware?

Well, I Supercharged my ROM now, which setting do you use to fix the problem? I'm still having it.
I even flashed a CM10 based ROM and its still happening! I think it's a hardware problem

Hi, did you manage to solve the problem? I'm having similar issues like you

[Q] Bluetooth wont turn on

Hello,
The problem is my bluetooth will not turn on at all, i slide the toggle to activate it and it stays grey for a few seconds and just turns straghit back off.
I've been a bit if a flashaholic the past weeks and have never noticed the problem untill now, im using the pheonix rom but the problem still occured in Omega v10.
Roms ive flashed recently;
MIUI India
Omegav10
Pheonix(current)
All roms flashed had been done so with a full wipe, im at a loss to what the problem is and considering going back to stock rom to see if that will fix the problem.
Im also using ext2sd mod.
International note 2 n7100, sorry for any typos im in work atm and posting on my break.
Thanks

Yep stock rom is way to go

Well flashed stock rom via odin, as soon as the phone booted back up i was greeted with constant errors of apps crashing, the phone would freeze and the only way to get it back on is to do a battery pull. Bluetooth is also still not working.
I'm at a loss at what the problem could be...

Answer the following questions sequentially:-
1.What ROM were you on when you found out the bluetooth problem?Stock or Custom?
2.Did you install a custom kernel?
3.What ROM are you on now?
4.What is happening when you click the bleutooth icon from the notification drop down bar?Is it giving an error or just simply refusing to turn on?

1.Custom - Omegav10.
2.Note2core Ext
3.Back to stock, "N7100XXALIJ_N7100O2UALI4_O2U"
4.When i click the bluetooth icon, it goes a darker green like its trying to turn on for a few seconds then back to the off state.

Do this.
1.Flash Omega again this time select Full Wipe option.(do take previous backups before hand and if you havent made an efs backup earlier,choose "Backup efs" in aroma installer)
2.After a good full wipe check again w/o installing any custom kernel.
Im on Omega v10 too and no problems here. One more question, did the problem start when you flashed v10 ? Was your bluetooth working fine before that
?

Doing so now buddy, yeah it started when i flashed v10. I came from MIUI india.
edit//
This is probably unrelated, but recently when i flash a new rom and boot up. perfomance is very choppy/random crashes untill i flash the note2core ext kernel.

That's superstition
Do a Full Wipe before installing a new firmware and you wont have any problems or grave performance issues.
I'll be going off to sleep now.
After flashing v10, if your problem is still not fixed, download this kernel:-http://forum.xda-developers.com/attachment.php?attachmentid=1634178&d=1357854682
and flash via CWM. And see if the problem is solved.
IF it starts working, do hit thanx.
If it does not, ill think of something else tommorow,
Good luck

Edit//
Just to clarify, I flashed pers/redpill kernels last night to check if the problem would resolve, but I ran into another problem where when the phone would go into sleep mode it won't wake up,
The only kernel that keeps my phone stable is note2core ex. Can this be due to the 1800 clock speeds on note2core? Arghhh this is driving me insane

Clear data and cache and dalvik cache.
Flash stock rom.
Root.
Triangle away.
Flash stock rom.
If the problem persist then take phone to service center

I dont have any idea.
One more thing you can try before giving to Service centre is do a Factory Reset from CWM.
Maybe that would solve.

Hi,
Have you followed this link http://forum.xda-developers.com/showpost.php?p=32273406&postcount=5&nocache=1 yet ?
I had the same problem as you then I followed the link.
My phone is back to normal now.
Hope you can fix your phone too.

Wow exactly the same problem i have and on same roms and kernel and yep also only seems stable on note2core now, i also flashed back to custom and still nothing i have noticed in settings it says bluetooth adress unavailable, is it possible the bluetooth drivers have been wiped ? Any help with this would be great or if you managed to solve the issue , maybe not relevant but my usb also does not work as mass storage or with kies but will connect to odin .

I am having the same problem. I installed a custom rom that messed my phone up big time. I went back to stock and everything works, except for bluetooth. I have gone everywhere I can think of to find a solution to this problem to no avail.

bluetooth and mass storage not working after flash
Hi...guys...I have same problem in my note 2 n7100
And its..if I install stock firmware still not working

I had the same problem too; the only solution I found out to solve the problem was switching to lupus kernel ( on stock ics ). Try wiping everything flash the latest official firmware with flash tool and then flash lupus kernel for stock ics and see if your battery return to work properly:good:

flash lupus kernel if you are on the stock kernel

Just flash any kernel difrernt from stock.
LuPuS v16 for example if you on 4.1.B.0.587 based firmware.

it worked..
Thanks everyone.. i reflashed the kernal again and it started working.. normally again.:laugh::laugh:
