Phone always switches off and battery drain with Siyah kernel? - Galaxy S II Q&A, Help & Troubleshooting

Hi,
I have a problem when i use any ICS rom with any version of siyah kernel, my phone always switches off at random times and i have to pull the battery to boot up again.....i usually wake up in the morning to find it off and with most of the battery life drained.
Every time i flash a rom i do the usual clearing the data/cache/dalvik/superwipe and kernel cleaning script and it still shuts down.
I have been using Phenomenal kernel instead and that works perfect and never closes or experience battery drain but i want to use siyah for doing dual boot.
Anybody got any ideas to what the problem may be?
Cheers.

well if dual booting is ur main concern then u can try
1)Dream Kernel- derivative of siyah with dual boot option and Xtweaks
2)Dorimanx- which again has Dual boot options

I think i may have tried the Dorimanx kernel and experienced the same problem, but i will try Dream Kernel and see how that goes.

Hello,
I flashed those two kernels and thought they were working but the same thing started happening again where my phone just randomly shuts down and i have to remove the battery.
I am using the Phenomenal kernel again and i don't get any problems.
Anybody got any idea why this is happening, i want to use dual booting on my phone.
Cheers.

Are you using ICS or JB based ROM?

I have tried both but most have been ICS, any rom with Siyah based kernel gives me problems, my phone could switch off after a few hours or days, then it is regular after the first shut down, i am not doing any tweaking or anything either, it happens when i am not dual booting too?

Is the Screen/Sleep Of Death (SOD) bug I've read about or something different?
Sent from my GT-I9100 using xda premium

Download CPU spy from the play store to see if your device is deep sleeping, and better battery stats from xda app section to see the wakelocks. It does sound like sleep of death too, have you undervolted your device?
Sent from my Nexus 7 using xda premium

Oh, don't set minimal CPU freq below 200 MHz, cause it results with SoD.

It is sounding like that sleep of death but why is it working perfect with the Phenomenal kernel?
I have not done any undervolting i have just been flashing the roms as they come, i will try CPU spy and better battery stats and see what they say.
Cheers.

How to diagnose cause of extreme UI lag?

What I'm running:
Latest NEAK kernel + AOKP build 36.
Issue also occurred in Phonebricker + NEAK (sammy version).
My issue:
Occasionally the OS will get extremely slow, like you would expect if the phone were running at 100mhz or something. Everything continues to work, just reeaaallly slow. For instance, music playback gets very electronic-y as sounds are stretched out, tapping one of the capacitive buttons takes 5-10 seconds before vibration/feedback, and another 5-10 seconds before a menu pops up. I managed to get the NEAK configurator open and scrolled to the CPU tab, and it claimed I was at 1200mhz - though the phone didn't even get warm so I'm skeptical.
I'm guessing since I've done a full wipe between phone bricker + NEAK and AOKP + NEAK, the only thing in common are my apps and the NEAK kernel, so it stands to reason it would be one or the other causing this. My wife's GS2 is running AOKP + NEAK as well though and we haven't experienced this problem on it yet (but it's intermittent so it might be there, just hasn't happened yet). I'm currently running conservative governor + SIO, but it has also happened on conservative + NOOP.
While I could just change a bunch of sh!t and hope it goes away, I'm more interested in figuring out what's causing it, and fixing it properly. How can I figure out what's going on? What will log this kind of thing? What do you guys recommend?
Thanks!
this is really easy/simple. flash a different kernel. all devices are not created equally so you need to just try everything that we have and see which best fits your device.
if you had this issue on 2 different roms with the same kernel then you've answered this question in your post for yourself. it wasnt even necessary to post this dude. change kernels. done.
some phone like neak kernel, some phones dont. some phones like siyah, some phones dont. you cant "fix" that unless you get a different phone and try neak again. but even then it my not "fix" this issue because nothing is broken.
Well, what if it's something as simple as the governor I'm using or an undervolt setting? I'll probably flash back to your kernel though, but again it'd be nice if I could figure out exactly what the phone is doing when it's "super-lagging".

If you're undervolting when this issue is happening, change it back to regular voltage.
I can attest to the slow downs and the screen lock ups. I have been using Tasks kernel for the past week and a half. Going back to try NEAK one last time. If it gives the same results I'll have to give up on it. I don't under volt hardly at all by the way. Like maybe -25 per step so it isn't that, and when I first experienced the issue I tried Evey possible io scheduler / governor combo under the sun. All yielded same darn results.

I've only used Task's (CM9) kernel and NEAK, and I haven't yet experienced any slowdowns with Task's, but I really have no idea what kind of optimizations his has, haven't found any information on it published so I can't say what's different between his and the NEAK kernel.
What kernels have you had problems on?

Stock & Siyah. My issue with it wasn't major; it just isn't as polished as GB. The difference is noticeable.
Sent from my Galaxy S2
When mine gets laggy, I usually pull out the battery and put it back after 10 min or so. If you are leaving the phone on more than 2-3 days at a time, that could really hurt the memory and phone performance. The phone usually runs on 300 mb but it will run about 700mb ram after 3 days (even force closing everything).
It is not mentioned so I just wanted to cover all bases
After posting about giving NEAK another try, I did. And within 10 minutes got an extreme lag slow down while typing. Didn't touch any settings kernel side. So I flashed siyah kernel and so far no problems. Sux too. I liked NEAK.

I have been running Siyah with Task's AOKP and have had zero lag and great battery. No UV or OC.
Sent from my SGH-I777 using xda premium
Posted this in NEAK thread but also posting it here:
I just installed the new AOKP, used kernel clean script and installed NEAK 2.0.5x, then went into the NEAK Pro config and changed my governor to Conservative and sched to SIO. Rebooted, opened Scramble with Friends and immediately got superlag.
Turning off the screen and waiting 20-30 seconds fixes it (long enough for the phone to go to sleep), but nothing else short of a reboot will help. I can leave it like that for an hour (if I don't let it sleep) and it'll still be uberslow.

[Q] Charging Animation Error With Resurrection Remix 2.2

3g, wifi,... All work fine, after I did a full factory reset and flashed v2.2 as an update coming from 2.1 on my international version GS2.
The issue that popped up is, that, while the phone is off, the charging animation seems to be gone and replaced with a yellow text saying 'charging! ??/100' so I can't really see the progress anymore
But when it's turned on charging still works like normal, and it does charge since it's 100% after a night of charging in deep sleep.
For this issue reinstalling the ROM did not seem to help (Other than that 2.2 just runs awesome).
Any information on how to restore the animation would be really helpfull.
I think that is kernel related... Try flashing a different one and see how it goes..
Sent from my hybrid SII with the power of ParanoidAndroid and Fluxi kernel
Yes it's kernel related thing, me too had the same problem before. You may try some other kernels recommended with the rom
Thanks, now that you mention it, this is the first version with CM9 kernel instead of siyah.
Loving the battery life on CM9 though .

try siyah ver3.3.1 it also gives good batt life the way CM9 and also can be tweaked using extweak app from market
Flashed Siyah 3.3.1, and got a nice green animated battery filling up while I charge. Thanks!
Any extweaks settings recommended to get the battery/performance comparable to cm9?

I flashed siyah kernel and no problems since, haven't had any issues with siyah kernel as of yet either!
Siyah battery life with the default profile on seems comparable to CM9. Is it true Siyah will stop releasing for gs2 and will only focus on gs3?

had the same issue and i just flashed Siyah and problem fixed. But just today i dont know why or how when phone is off and instead of showing the little circles moving when charging off I have just like the reflectuion or shadow of the green battery. just weird the phone seems normal no issues just some drop calls but i just wana gp back as before
Maybe try flashing it again using the same procedure as with a rom (wipe cache, flash, wipe dalv...)?

No, it is not the kernel. It is a bug in the ROM, that hasn't been found or fixed yet. Restarting resets certain phone data.

It has happened always since ICS update for me, with all ICS ROMs I have used, with all ICS kernels I have used.
Restarting does the deal. I restart my phone every morning anyway, to clean up the memory/CPU, so phone will be faster.
It dosent happen with stock extended kernel..earlier it happened to me when I switched to krsh kernel aftet that I flashed extended kernel and and install custom rom like rs lite. With wipe data and format and this bug dissapeared..then it never came back
Hope it helps

In my experience so far concerning battery life, the kernel plays a huge role.
Stock kernel is a big drainer. Rage kernel is very good with battery life, as is KRsH kernel.
Flash a custom kernel, and set CPU governor to smartassv2, svagedzen or brazilianwax. Those 3 are in my experience the best.

Thought so.. that it was related to the Kernel.. I'm on extended stock kernel now and the battery life isn't as bad as stock ICS. Although I really haven't kept track of the exact battery life on this kernel, but it's certainly better than Stock ICS.

I've had similar problems when my usb port got burnt, and battery indicator constantly kept showing 'charging' icon, even thought cable was unplugged. Apparently some process/service (related to USB connectivity) prevented OS to go to sleep, and that kept draining the battery... Thanks to warranty, phone got fixed, and since i havent experienced any battery drain. Last time i checked, i got up to 3 days without recharging the battery

Terrible battery drops

Hello guys, I have made this thread for asking solution for a big issue my brother is facing on his S2. He is on official ICS. I've rooted his phone too. The issue is he is having terrible battery drops. Battery doesn't even last for 4 hours. I was shocked to see the graph. Please can anyone tell me how do I get him rid of this issue?

Ill try it on him for now and see. He is blaming me for the battery issue coz I forced him to update his phone to ICS.
Flash stock ICS again and wipe data.
ICS gives less battery backup compared to GB.
Turn off WIFI/2G/3G/GPS after you use them. Download Better battery stats.. see if you have partial wake lock due to some app!!
4hrs of backup can only be due continuous gaming or 3G.. it drains battery!!

Try a custom kernel, I recommend Speedmod or Siyah.
Irrespective of the Rom you are running, the kernel and modem have most impact on battery life
Swyped from my Galaxy SII
Ok guys a quick update. I installed Cpuspy and betterbatterystat and found that phone goes in deepsleep very well. No app causing wakeups. So is flashing a new kernal the only option now?
Ok planning to put in SiyahKernel S2-v4.1.2 kernal. Any issues with it as in known bugs?
I'm surprised that no app is responsible for such terrible battery life. Usually its the Network Locator by Google maps or the the GTalk sync that causes the problem.
Anyway if you're sure its not any apps fault flashing a new kernel is the only way to go. As Jokey recommended, try Siyah or Speedmod.

Explanation:
-flashing a custom kernel has nothing to do with apps
-What kills battery most in stock kernel apart from apps and radios is the kernel - worker and fuel alert wakelock.
-in your own case since no apps is causing wakelock, then a kernel can be of help.
My advise:
-If you are presently satisfied with your battery life, then there it's no need to flash any more thing
-If you are sure no apps drain your battery, but still not satisfied with your battery, monitor that,
i. 2G network saves more battery than 3G, 4G
ii. Turning off Bluetooth, GPS, Autosync, Wi-Fi, Network location (under settings-location), App notification and Google ads in Google playstore settings, saves a lot of power.
-Connecting to a Wi-Fi network saves much more power than using mobile data
-If after trying all the steps above, you are still not satisfied with your battery, then you might have to flash a custom kernel.
-Most custom kernels save much more power than the stock kernel
i. Speedmod kernel gives relatively best battery life if you don't want to change anything. This may be good for you as a beginner.
ii. Siyah, Dorimanx and dream kernels give great customisation.
Hope you find this post helpful enough.
If you have more questions,do let me know.
Good luck

It might be a hardware issue then. Try flashing stock, if still happens means hardware issue. If not, most probably the custom roms.

When I first got my phone on stock S3 firmware, it lasted 5-6 hrs with minor use. If you want to make the custom roms last longer on KitKat, stay away from Archi, undervolt and underclock the cpu. If you want it to last an insane amount of time, enable flight mode. ;DD
