I'm running CM9 with Popcorn Kernel v8.2.1 and I keep getting wakelocks and my battery dies very quickly. I attached screen shots hoping someone can help me fix the problem.
use battery better stats and set it to partial wakelocks and find out whats preventing ur phone from deep sleeping.
First post in the correct section which would be Q&A.
Second do you still have those wakelocks after a factory reset and reflashing the rom without the kernel?
If not then flash the kernel. If everything is fine until now it was either a random bug or a missbehaving app.
Media scanning.
Just run the stock CM9 kernel already.

I was running the stock CM9 kernel but it is nowhere near as smooth and fluid as the Popcorn Kernel v8.2.1.
Is there a way I can get it to be as smooth by changing something in the performance tab? Any setting recommendations?
definitely "media scanning" is the cause of your battery drain.. i dont even have that in my battery history so I'm not sure how to approach this.
best thing I could say is that try another kernel or ROM and see if the problem persists..... or view the thread of your perspective ROM / kernel and search to see if anyone has a similar problem.
things that eat battery very fast: 4G, GPS, bad signal area, bluetooth, apps with ads in them, even though app is not on your screen ads may still be running, close apps w ads from the multi tasking button. Wifi increase your battery life.

ITS THE SCREEN!!! LOL All that other stuff is small potatoes! Plus I dont think the Multi tasking section actually closes apps.
Well obviously the media scanner is stuck. It might just be CM9. Clear cache and let it repopulate your media.
Return with results.

I removed Chrome before and it still ate battery. I think it was the v8.2.1 Popcorn Kernel. I don't have that issue with the kernel bundled with CM9 BUT the Kernel bundled with CM9 isn't as fast or fluid.
Should I change my governor settings for best performance? If so, to what?
On previous devices where I had Media Scanning running rampant like that, the easiest fix that worked every time was to backup the data on my internal and external SD cards (internal in our case), format them both then copy my data back over.
Any luck on this? I have two batteries and I am having trouble making it 8 hours. The extended & Standard battery.
That kernel may not run well with CM9. I know the frankokernel horribly reduced my battery on gummynex and I was also getting a lot of media use in the stats. I switched back to lean kernel and its all good now.

I had that problem once on my Nexus One. It stemmed from a corrupt jpeg file on my storage, it was a picture I took. The media scanner choked on that, and so did Windows when I transferred it back to my computer. As soon as I removed the file things got back to normal.

This post only pertains to Jellytime Sosei/BakedBean 4.1.2 and is for users experiencing problems with their A100, yours may not. This thread is not to debate or argue about the kernels, please keep that in mind
Hey guys, I was originally testing these ROMs for pio, and constantly am changing or tweaking things on the ROM to find what suits our A100 best. Pio was building these blind, so he has no way to thoroughly test the ROMs and such things as build.prop mods/tweaks as well as kernels.
Let me start by saying this, I AM IN NO WAY BASHING ANY DEVELOPER FOR THEIR WORK. I AM IN NO WAY BLAMING OR STATING THAT ANY BUGS/FLAWS ARE A DIRECT RESULT OF THEIR WORK. THE THINGS I AM LISTING ARE ISSUES/PROBLEMS/BUGS THAT I HAVE OBSERVED OR ENCOUNTERED, AND ALL BUGS/FLAWS WERE TESTED AGAINST THEIR EQUAL. EXAMPLE, USING THE godmachine81/linuxsociety KERNEL, THAN REPRODUCING THE SAME ENVIRONMENT, I WOULD RUN THE STOCK KERNEL FOR TESTING AND VERIFYING THE ERROR.
Kernel Observation:SODsEveryone, including myself, tend to automatically flash linuxsociety's GodMachine kernel v2.0, as it really is our only option for JellyBean/CM10/AOSP based ROMs. We do have ezTerry's kernel, but it has not "supposedly" been tweaked for 4.1.x systems. Although it is the base for GodMachine kernels. I've never used ezTerry's kernel,but I may test it like I've been testing GodMachine.
Anyways, for this ROM, I have found that the godmachine kernel performs poorly on Sosei ROM. With GodMachine kernel, I had tons of issues with constant BSOD/SOD. (Sleep of Death) The SODs were worse if you left wireless on, and the SODs were completely random, no matter what I did, if the tablet fell aslepp, it SOD'd on me. Using the stock kernel pio packed with the ROM, resolved much of this issue for me. The only time I have SOD on the stock kernel is when Wifi was left on, and the chances of this happening were 99% LESS LIKELY compared to GodMachine. You can combat this, by sacrificing battery life and using an app that's free on the playstore, WakeLock. If you choose to go this route, the "Partial_Wake_Lock" option consumes the least amount of battery while still preventing SOD. None of the 3 options for forcing wireless to stay on worked for stopping SOD.
RANDOM REBOOTS/CRASHING/FREEZINGI myself did not have many issues with random reboots, but I did have some issues with random app "force closes" and freezing to the point where you'd have the almost force close I call it, where you get an option to close or wait for the app. I have not had this issue using the stock kernel, unless related to the next topic...
GPU/VIDEO INSTABILITY/ODDITIESI, as well as a few others, have reported issues with display. Most users have noticed an issue with flashing lines, tearing, and artifacts on the desktop. I have also had issues when play a THD/HD game, for example Modern Combat 3: Fallen Nation HD, where anytime after about 20-30min, the display would become compltely distored, almost like when you were trying to pick up a TV station using rabbit ear antennas, and the game crashes/freezes, but you do not get an option to force close, so you have to use the Navigation bar HOME button to get yourself out of it, than you need to kill the game anyway you want, but if you don't kill it, it will load you back to that distorted, frozen image.
In the GodMachine kernel, the GPU is overclocked as well as being able to overclock your CPU, but you cannot adjust the GPU yourself with any application. Linuxsociety states: "Stable GPU Overclock @ 450mhz (scales from 300 - 450)"
I do not have these issues with video when using the stock kernel, nor do I notice any lack of GPU performance with lack of GPU overclocking.
In my honest opinion, I STRONGLY RECOMMEND the STOCK KERNEL. Yes it is lacking in some features, but it is capable of being overclocked as well if your interested in doing so. Using the interactive governor provides the smoothest performance and still retains some battery savings. Conservative, OnDemand, userspace, and Performance are offered as well. The I/O Scheduler only has NOOP available, but if you do some reading, NOOP is actually recommended for Flash Devices, like ours.
To get back to pio's stock kernel, you can boot into recovery, wipe cache and dalvik, and dirty flash the ROM.
BUILD.PROP EDITINGI cannot even begin to tell you the amount of hours I invested in testing and editing the build.prop to obtain what I find to be the most stable while still possibly enhancing performance/responsiveness and battery life. I will link you to my FINAL build.prop mod for you to download if you'd like. In all reality this consisted of just commenting out several lines in the original build.prop that our A100 did not like. This will also fix issues with the video camera recording if you have them, as well as improve certain app and system performance and functions. I've also had more reliability and just odd **** happen when I use the TCP/IP buffer enhancement code lines so those have been commented out as well to keep WiFi stable. I really see no performance gains with them other than SpeedTest and there is a reason, I am a Networking IT Student, and don't feel like explaining that now in this thread. lol
Download build.prop.sosei__tweaked
Using a FileExplorer with ROOT LEVEL ACCESS (I recommend ESFileExplorer),
Copy build.prop.sosei__tweaked into the /system folder
Rename current build.prop to build.prop.bak
Rename build.prop.sosei__tweaked to build.prop
Reboot into recovery (TWRP or CWM) and wipe dalvik cache & cache, reboot
make sure you wait ten, reboot and wait 5-10 before you start using your tablet
This is all in my observed, hands-on testing and experience, and everyone's results will vary based upon factors such as user setup, apps install, the way a user even uses their tablet etc
I hope this might help/inform some of you guys.
Very nice, thanks for taking the time to put this together for the users. How did that kernel I built for you do?

I hadn't flashed it yet as i had gotten my tablet into a perfect state, for me, with this ROM and stock kernel, lol
The changed prob won't stop sod, but in my theroy should correct the video glitches.
I'll try it soon and let you know.

I'm using/testing this rom along with gm's kernel. I have not had wake SOD issue. It sometime takes a couple if clicks on the power button for it to wake, not sure if this is the issue you're referring to as SOD. Everything seems to work great so far. Netflix, audio, headphone all work well. I have always wanted some aokp flavor on this tab, and now that wish is granted thanks to the awesome work of pio, bb devs and gm.

No, I had sod constantly. But not slow wake up. I get slow wake sometimes on stock, but atleast it will wake.
Everyone's tablet is not the same, some hate the GM kernel.
Mine seems to be one of those, but had I known how smooth and stable the stock kernel was, I prob would have stopped using GM awhile ago, I've had nothing but issues with it, if you've seen any of my old posts over last couple of months.
G2x-temasek CM7 Nightly 11/18/12 Build, Trinity ELP Kernel
Other than a couple of SOD's I haven't had any other issues with the gm kernel. I have since bumped up the minimum speed to 312 Mhz and that has seemed to fix the SOD issue but I still need more time to conclude that. I'm also getting some impressive quadrant scores with it too (3046) and that's with a fully loaded non-tweaked system. The only reason I like the gm kernel is the variety of I/O schedulers and governors...there is absolutely nothing wrong with the stock kernel. I'm still very happy with the JB ROM, I have it set up almost identical to my Samsung Nexus phone which makes it very convenient.
GM SOD Issue Resolved ( For Me)
I can now safely say after 4 days of testing that raising my minimum speed in the GM kernel to 312 Mhz has completely eliminated the SOD issues. I know that every device acts differently but this is working on mine!

I didn't want to do that myself and lose the extra battery juice.
The point is it should be able to UC down to 216 and hold there with no issues.
The stock kernel does it perfectly well with no ill effects.
I have a modified Godmachine kernel that is unreleased and I will be testing it soon.

thanks for the tweaks and info! buti have never encountered a SOD. what happens? it just wont wake up after sleeping? if it happens can you just turn off your tablet by holding the power button or do you have to wait for it to die?

SoD is just a failure to resume from sleep, reset button or hold power will reset it to normal. Some tegra2 devices have it, some don't, even among the same series, like a100s. The best way to combat it is to not sleep, but of course battery sucks.

I can understand not wanting to lose the extra battery juice, lots of what we do is to extend it. I did however undervolt the 315 slot to the same as the 216 (750 mV) so there's no addition battery drain. It's a win-win situation! Let us know how the unreleased version works out, I'm always looking for options.

I'm kinda new to the S3 and have mainly stuck with TWIZ roms, I've tried a couple AOSP roms but found that the battery gets hot as hell quickly either while charging or using and the data connectivity is spotty at best on AOSP, I have LTE where I live but rarely see it on AOSP. I've updated PRL and profile and radios...but no luck...can anybody help or point me in the right direction? Thank...
Sent from my SPH-L710 using Xparent Skyblue Tapatalk 2
well generally twiz roms are more stable than aosp roms... so id stay in the TWiz sections... but thats all i can say
AOSP ROMs typically run the CPU harder. While TouchWiz ROMs use more RAM. Thus why AOSP ROMs typically, emphasis on the 'typically', run hotter than TouchWiz ROMs. There are ways around this. For example, messing with CPU governors and settings. I have found ktoonsez has kept my AOSP ROMs fairly cool, relative to the default. Heat also means battery drain. So you will find here that TouchWiz ROMs normally have better battery life. I highly recommend CleanBean 4.1. Very nice ROM. Complete, stable, very quick and snappy. While no sacrificing battery life, as I was able to squeeze out about 14-15 hours. Good luck

While I agree that AOSP ROMs use more CPU and TW use more RAM, for me AOSP had the best battery life. Espicially when I'm running ktoonsez kernel I get a good 3+ hours screen time and a total of 20 hours easily. While on a TW ROM running ktoonsez I get maybe 2 and a half hour screen time with a total of maybe 12-15 hours of total battery time. Also for me the only time my phone gets hot is when my phone is charging and I am using it constantly or I'm playing graphic driven games.

Flash freeza's md4 firmware then clean install Liquidsmooth 2.5 then their gapps, thats it, leave the kernel that comes with it. No more heat, everything works perfectly including LTE
Just recently my phone too has become hot. But the only thing I've changed is the micro SD, from 32-64gb. Could that be the reason why?

Must have missed that . At this point I would try a different Kernel. I suggest Ktoonsez Kernel.
If anyone is still having issues here.
Apps repeatedly doing wakelocks, Phone becoming hot while on standby or on charging indicates that theres a ton of background processes going while its charging.
And that includes weather updating, widgets with high refresh rate, auto-sync enabled automatically to turn on or off via file tweaks or utility applications.
I've been using CarbonRom and the only time it gets hot is when the phones at it's peak playing graphical games.
Mines is stock kernel but I have tweaked scripts that turn off my CPU's 2nd core while on standby,
and having SetCPU Auto clock the processor to be at its 2nd lowest to very lowest while screen off, and have
it clocked midranged 702-801 while screen on without doing any UV or OV.
I would also have force GPU Rendering checked and disable hardware overlays when im not using anything on the phone.
My battery life is 6-10 hours screen on web browsing, reading articles, watching movies / videos on netflix ~ Depends.
If I charged the battery and calibrate it and left it off standby without touching it, it can last around 3-4 day's depending on my
background wakelocks on messaging or any type of SMS or alerts recieved.
Also using Greenify to hibernate Ram hungry apps. and I'd usually freeze certain apps that aren't killable to save battery life.
GAPPS
ROM
This version includes openpdroid, but PDroid does NOT work with ART (bootloop). To use PDroid, you'll need to install PDroid Manager from the play store.
ROM (1/4)
The linaro toolchain seems to reduce 3D Graphics and RAM performance slightly, so I decided to build without it for now. Still ART-default.
ROM (12/30)
Built normally this time, no extra optimization flags. ART is the default startup for this build (supports Dalvik, ART, and ART debug, the non-default two were unintentional, but I don't know how to remove them). It takes a little bit longer to start up than the previous build, but the performance is about the same, if not a little better.
ROM (12/29)
Observations:
Make sure you install CWM Recovery and stay on it while you are using this ROM, since if you install through TWRP, your SIM card will not be recognized.
I don't exactly game on my Android, but I've yet to see issues with ART. If a game does crash on first start, try to start it again, it worked for me the second time.
I didn't exactly test this long enough to say anything about the battery, but it's quite smooth so far.
I'll update this thread again in 12 days, or whenever I figure out how to make it ART-only.
Changes from nicktastique's version:
See attachment for my repo manifest (Uses TheMuppets for proprietary files) (yes, it takes longer to download, but nicktastique's local_manifest kept failing to build for me, possibly because I was using Java 1.7 until I realize I wasn't supposed to)
Built with Linaro Toolchain 13.11 (4.8)
Code:
mka CFLAGS='-O3 -pipe -Wl,–hash-style=gnu -fstrict-aliasing -Wstrict-aliasing=2 -Werror=strict-aliasing -ffast-math' CXXFLAGS='-O3 -pipe -Wl,–hash-style=gnu -fstrict-aliasing -Wstrict-aliasing=2 -Werror=strict-aliasing -ffast-math' bacon

Not that I've come across. Still testing. Passes the 3D benchmark from Antutu too.
Throughout CM 11 though, I've seen GPU tearing in Chrome Beta. Perhaps some Developer Settings may fix it.
Benchmark-wise, insignificant change in the cpu (+.3%), some improvement in Database I/O (+2%), some improvement in 3D graphics (+13.26%). However, RAM speed suffered (-7.3%)

Works. Found a bug tho. When I listen to music using my Bluetooth headset, its fine until I put the phone to sleep. When I put the phone to sleep, audio starts skipping. Other than that, this ROM kicks ass. The BT issue seems to be on all 4.4 ROMs tho.

No idea, haven't tried it since I don't own anything it would work with.
Let me introduce myself first. I have been developing software for Windows for almost 20 years. I love to tweak and tinker. That is what drew me to the Android platform. With that said, here are my findings:
I own a T989. I love the phone. I have tried numerous tweaks and scripts etc out there. In the end I found some very minor tweaks that I have done manually that make a noticeable difference in performance and a battery life.
The biggest increase in performance and battery life that I had noticed was going from a stock rom to CM 10. I am currently on CM 10.2 (and eagerly awaiting a stable version of CM 11).
With that said I noticed that if I changed just a few minor things CM 10.2 runs considerably faster.
Here is what I have done:
1. Disabled ZRAM completely. I have noticed that my phone boots faster with it disabled. I noticed that multitasking was not as good with it disabled but the phone seemed much snappier.
2. Changed Min Free values. I used the Performance Control app for this. My settings are currently as follows:
Foreground Applications: 16 mb
Visible Applications 18 mb
Secondary Server: 23 mb
Hidden Applications 42 mb
Content Providers 49 mb
Empty Applications 56 mb
This seemed to help a lot with multitasking and now it multitasks fast and the phone is much snappier and less laggy. So far my phone is very stable and fast.
3. Set SD Card Read Ahead to 2048.
4. I also left KSM disabled and left Allow purging of assets disabled.
That's it. My phone is rock solid stable and fast with these settings. I also noticed that my battery lasts about 15% longer. Even better than just switching to CyanogenMod 10.2 alone.
Let me know if it works for you.
I would absolutely love to try this, but I don't understand majority of what you wrote. I'm familiar with cyan though..

I then changed it to the new values above and used it very heavily. I made sure at least 18 apps were open then reinstalled those same apps from the Play Store (I uninstalled them first). So far no problems.

Is there a way to disable ZRAM on a rooted stock T989 running 4.1.2?
Thanks in advance,

As far as I know the stock ROM doesn't have ZRAM.

Let me introduce myself first. I have been developing software for Windows for almost 20 years. I love to tweak and tinker. That is what drew me to the Android platform. With that said, here are my findings:
I own a T989. I love the phone. I have tried numerous tweaks and scripts etc out there. In the end I found some very minor tweaks that I have done manually that make a noticeable difference in performance and a battery life.
The biggest increase in performance and battery life that I had noticed was going from a stock rom to CM 10. I am currently on CM 10.2 (and eagerly awaiting a stable version of CM 11).
With that said I noticed that if I changed just a few minor things CM 10.2 runs considerably faster.
Here is what I have done:
1. Disabled ZRAM completely. I have noticed that my phone boots faster with it disabled. I noticed that multitasking was not as good with it disabled but the phone seemed much snappier.
2. Changed Min Free values. I used the Performance Control app for this. My settings are currently as follows:
Foreground Applications: 16 mb
Visible Applications 18 mb
Secondary Server: 23 mb
Hidden Applications 42 mb
Content Providers 49 mb
Empty Applications 56 mb
This seemed to help a lot with multitasking and now it multitasks fast and the phone is much snappier and less laggy. So far my phone is very stable and fast.
3. Set SD Card Read Ahead to 2048.
4. I also left KSM disabled and left Allow purging of assets disabled.
That's it. My phone is rock solid stable and fast with these settings. I also noticed that my battery lasts about 7% longer. Even better than just switching to CyanogenMod 10.2 alone.
Let me know if it works for you.

Running JMT8 right now, and this has been one of the best posts I've seen on this forum. All roms I ever flashed would be snappy for the first couple days then slow to a crawl after a month. This has brought this phone back to life and prevent me from having to flash all the time. I wasn't able to do the ZRAM disable since I don't think I have that settings, but I updated the min-free settings and have seen noticable improvements. Thanks!

What does this do exactly?
Will SD Card Read Ahead 2048 not reduce the life of the SD? (and by a lot since my current ROM was 200% less.)

No. In writing a lot over time can possibly reduce the life of the SD. I don't believe that reading will.

I use ROM Toolbox to benchmark. 2048 usually yields better results overall.
