Wel, I was having pretty good battery life with the L710's stock MA6 ROM with KT747's kernel but I decided to flash a new ROM.
Here is what battery life looks like and I'm worried that its not the ROM but a problem with my battery, since people have been reporting exceptional battery life with this ROM.
Some specs.
ROM: LIQUID-JB-2.1-STABLE
Kernel: KT747-Kernel-AOSP-JB-MR1-SPR-03-14-2013
Governor: ondemand
Scheduler: cfq

Attached is the battery screenshot.
It won't even charge when connected with light use. Thoughts?
Before anyone asks this is my third time installing the ROM and I'm pretty sure I don't have the Google services wake lock.

O the three times u installed did u do a full wipe (wipe data factory reset ) also are you over clocked and did u restore old kernal settings.

I try to never dirty flash and usually just restore apps from TitaniumBackup. All three times were full wipes formatting any partition I could other than extSdcard. No old kernel settings were restored and I'm not over or undeclocked but I did under volt by 50 and the phone seems stable but no improvement.
As a matter of fact during the latter of the installs I restored nothing. I've also disconnected my sdCard in hopes that it was a bad card (some hopes) but to no avail.
I am redownloading the rooms even do the md5 sum was the exact and downloading the gapp from a different source.

Try running LiquidSmooth's stock kernel. I'm getting pretty good battery life with that. KT747 may not agree with your phone combined with this rom. I had good results when I ran KT with a TW rom, but not so much with AOSP. Every phone can behave differently.
Good luck.

I ran my phone with the kernel that LiquidSmooth has as stock, and it was extremely buggy for me, maybe it just did not behave well with my phone but it looks like the kernel has a few known issues as is. One bug I had is that audio playback was extremely erratic, and I haven't come across a commenter stating anything similar. I'd really hate migrating from LiquidSmooth, especially with the notion that I just "gave up", and not on just any release but on a stable release.
Update:
Update:
On this new install from a new download and gapps from a different source, I do not seem to be having the audio issue, which seems strange as both prior downloads had an exact md5 sum.
*Currently hopeful with fingers crossed*
I'm really enjoying LiquidSmooth, too, so I know what you mean. I hope it works for you this time.

Hello all,
I recently purchased an S3 and just trying to figure everything out for it (as I am coming from the nexus where everything is much simpler) The only real question I have for everyone is, What kernel is the best so far? Something that is optimized for battery life and speed.
If anyone is from the Nexus development you would know about Franco's kernel which has served me well for a long time, So what I'm looking for is something that is like the Franco Kernel, and has customization settings.
Any insight would be great
Cheers.
When running an AOSP JB ROM (like CM10 or AOKP), I'd suggest ktoonsez's KT747 kernel. It supports overclocking to 2.1 GHz, undervolting, comes with numerous tweakable governors and io schedulers, and it comes with its own adjustment app called KTweaker which is very handy. Just don't use SetCPU or Voltage Control or any other such app with that kernel as they could cause conflicts with KTweaker.

The current KT747 for Sammy ROMS seems to be having issues with many phones though, so for Sammy ROMS I'd say your safest bet is faux123's kernel. http://forum.xda-developers.com/showthread.php?t=1785466
Much appreciated. I was seeing ktoonsez's KT747 kernel, and figured this was the "main" kernel for the s3 but I just had to know for sure. What you describe with it is exactly what I'm looking for in a kernel...full control of it. Thanks again
Also on KT747 ktoon created his on governor called ktoonservative. It's based off conservative but it's kicking some serious butt with my device :good:. I'm also severely under-volted but that shouldn't really change much as far as battery life.

I tried the kernel (both actually) and had no luck with either, one caused everything to fail ie: wifi, data, launcher, touch screen was unresponsive. And after flashing in the other one that says it is 100% stable on all devices, I was left with a phone that wouldnt turn on, and when it did start up, the screen was unresponsive. I tried clearing caches, fixing permissions, but nothing worked at all.
So I went back to stock kernel. Hopefully some of these issues can be resolved some day.

Are you sure you flashed the correct version? Both kernels come in ICS and JB flavors.
Also, I haven't seen anyone else with this issue so I'm not sure what happened.

Never seen these problems before.....
Are you sure you downloaded and flashed the right one?
DAMN I MISS FRANCO KERNEL!!!!!!! It was on the note n7000 in a way I wish it could come to the S3
I've tried looking for the definition of "SOD" but couldn't find it. what does it mean? (sorry if it's a noob question)
also, i've been running unofficial JB roms from Cyanogen and AOKP, but both of them randomly freeze up and restart my phone. and when they try to restart, they dont do anything after the initial samsung logo pops up. any possible explanations for that? i figured it couldn't be a bad download when it happens with two different roms...but i could be wrong. should i flash different kernels? and any way i could expand my battery life on ROMs? my battery sucks on most ICS/JB roms...
Sod is sleep of death.
Did you try darkside cache wipe? That could fix boot loops

i did, but im talking about the ROM actually working and in the middle of an application or something, it'll freeze up and try to restart. and i have to take the battery out and put it back in for it to completely boot up again.
AFAIK what you describe is sod. Freeze and have to take out the battery to reboot. RR=random reboots, where it reboots ant not freeze

Actually, SOD is the behavior in which the phone goes into "sleep" mode... typically screen off, and then won't wake up with power button.
From what i've read... SOD happens when you do really aggressive clocking to save battery life. There seems to be two states of CPU, when the screen is on, and off. Depending on how / what state / governor is used... you could get SOD. I forgot all the various threads I've read this on... but search for it and you should find a ton.
The behavior you're having is more of an RR than a SOD. Granted you're freezing up. The better question is... are you following all of the ROM OP's instructions? Have you been RESTORING apps from backup? Bottom line is... DON'T.
DON'T install zip's/mod's that aren't included and validated by the OP. This includes kernels. The JB CyanogenMod and AOKP threads I believe say don't flash any other kernels yet.
DON'T restore from backup. At least don't do it until you know you're stable with just the ROM itself.
That'd be a start...
No need for battery pull. Just hold down power button till you feel phone vibrate. Between 10-20 seconds.

ahh i see. well that's annoying lol. ironically, the battery life is still not that great on my ROMs haha. but yeah i did follow up instructions from the OP. now when you say restoring apps...does that include things like messaging? i don't restore things like facebook/group me/flipboard or anything like that. usually just messaging and call storage data that i restore via Titanium Backup. does that count? and no i also havent tried to install any mods or kernels of my own. i usually just use the ones that the ROM comes with.

Thing is, I've been running the latest builds of CM10 with little to no SOD or RR issues and I've been restoring data from backups of the previously nightlys builds using TWRP. Granted, each phone is different... But each phone is different lol. Precautionary advice is good I suppose, but to me it would create a hassle if I had to start with fresh data on my apps whenever I updated. Of course, I don't report bugs, but I'm sure a lot of users don't regardless.

i was thinking about it, and i've heard pretty much nothing but great things about TWRP. i used CWM non touch ever since i rooted my S2, but i have a feeling that it's getting outdated fast lol. you think flashing with TWRP has anything to do with your phone's performance?

Ok so to make a story short:
I installed CM10 M2 wednesday, everything went AWESOME. Smooth, responsive, fast! Pure JB awesomeness. Then, satuday i decided to flash Faux123 kernel to have additional governors and from that point, everything has been terrible. The phone has been extremely laggy, it randomly rebooted and sometimes when i turn off screen, it doesnt want to turn back on and i have to battery pull.
Since that, i have formated the phone at least 5 times, i tried just a factory reset, complete wipe through CWM, reflashing rom, but nothing worked. What really weirh though is when i reflash the rom, and reinstall all my apps and put everything back, until i reboot the phone once, the phone is smooth and stable. But as soon as i reboot the phone, i'm done. It becomes laggy again, reboots and has sleep of death.
I'm really perplex as to what can cause this. I honestly am just about to ODIN this phone back to stock and just wait for official JB...thats unless somebody here has a quickfix?
I'm assuming when we reflash rom it also reflashes kernel, maybe reflahing just the kernel will solve this? anybody got a link? or a kernel to suggest?
EDIT: Now i can reproduce the problem. Everytime i turn off screen and i turn it back on shortly after, it reboots
Try ktoonsez kernel. He seems to be putting more updates than faux. Faux hasn't updated since August and ktoonsez updated 5 days ago.

No he does update his kernels he just doesn't update them on original thread. My build version is Oct 13th. But ktoosez has cm10 kernels?

I agree with d3athsd00r, Use ktoonsez kt747 kernel. Im running CM10 M2 as well and everything is fine for me, especially a significant improvement in battery life

Ok, i've just installed Ktoonsez kernel. I have changed to different governeors and i've yet to have seen any lag. Thats a great sign. Juste one question though, what combo of governor + scheduler gives the best battery life?
bump
I use ktoonservative and bfq, but there is no "best" What works best for someone else might not work well for you.
Testing is the only way to answer this for yourself.

Just wondering what the best kernel is to flash to the stock UCLJ3 rom?
I'm suffering crazy battery drain since updating. I've done a ton of things including a full wipe and reflash, and it's still happening.
Only thing I havent tried, or done before is flash a kernel...
Any recommendations?

Haven't had any trouble with the battery drain using IcePop rom! but of course flashing any new rom, you have to let it settle for 1 to 2 days / charge cycles for the os to stabilize!
I've been running it since day of release.... Using battery apps all reports that the Android OS using a heavy % and/or the phone isnt always going into deep sleep.
And its happening even before I put a google account on or install any apps.
I suppose I could go back to G9 or the H2 release... might do it as a test, to see if it really is the J3 release thats causing me problems.

Which kernel are your running? Also check to see what your cpu governor is set to! Use system tuner from the market

Just the default I think... I dont believe I've done anything more than flash an entire ROM, and mostly rooted stocks.
Gonna give that app a try though, thanks for the tip.

I'm hoping to release a new an updated version if not tonight maybe by Monday! battery life should be good.
keep in mind that a deodexed rom will use a little more power!
Thanks
Hi,
My GN was fine when I purchased it a month ago, brand new, but its so sluggish that its almost unusable. Phone dialer, Messaging and almost all apps load with a 3-5 second delay, even the keyboard opens after a few seconds.
I'm on stock 4.2.1 (deodexed) and even flashed fugumod kernel just today hoping it would fix things, I even factory reset it but no joy.
Could it be a hardware issue? is there any way I could run some quick tests to see whats wrong?
A similar thing happened to me when I decided to try a new kernel I've never used before, and it did not agree with my phone. Try a different kernel like lean kernel or Franco kernel and see if it still happens. If so, go back to stock.

I was on stock, then tried FuguMod, but it still lags, not as much as before but pretty slow.
Do you have lag spikes? Like many little freezes?

I have thr same problem...from like 30 to 30 seconds I have those many little freezes...i tried many roms/kernels but no succes,even flashed the stock images and it's the same...I think something is messing our CPU cuz i had this issue even on stock rom/krrnel

why dont you flash to 100% stock and see if the problems still persist?
Franco's kernel always good. I gave my gf my gnex never had a problem with sluggish she loves it.try going back to stock and redo everything start fresh and see if it still persisting

Have you used up almost of your memory in the sd card? I don't know if GN's are affected by eMMC bug brick. I've asked this before but they said GN is not affected. It has something to do with a bad chip.
