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.

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.

lol 1400/200!?!? theres ur 1st problem. use voltage control instead of setcpu and stick with 1000/100 or 1100/100. i always found cfq and conservative to be nice for battery, but apparently noop/ondemand is best. maybe try both. also turn data off when not using it most importantly. also try using the auto-start manager in the ROM Toolbox app (free in market) to disable most of ur apps from staying open or updating widgets constantly in the background. freeze system apps you don't use. forget the v6 supercharger, and i'd say stick with the stock kernel. hope that helps..

If you turn of 3g data, you can still send/get phone calls and texts but no email
Also, undervolt you frequencies with voltage control, I don't think you have to go to stock kernel, but do as you please I would imagine the dark blacks from voodoo control would save battery. But anyways, Marcusant had a great guide for setting up any kernel for your phone, ill try to find it..

For that reason, i wouldn't bother doing it..but it's up to you. as for voodoo color you might be right about the blacker blacks..i just noticed on cm9 that the stock kernel saved more battery for me so figured it might apply on aokp too cuz its so similar

Ahem what battery life oh okay
I haven't figured out what is so different but I get much better battery life on AOKP than CM9. My imagination or is something really different on the roms? I don't use the power saver feature because I need my data all the time.
Im running Stock Build 31 on EL30 modem and no custom kernel nor am I oc/uv. I have very few apps and I have no widgets running and im getting horrible battery drain. I purchased the 1800 battery which is a few months old and I just dont know what to do. While my phone is sleeping, the battery drain hardly even moves, but when I start doing simple things like texting or checking emails I start getting drops of 2% percent or more every 5 mins of use.
Any Suggestion would be great.

I wanted to investigate the sporadic freezing in my Galaxy S2. So, I turned on, show CPU usage under the developer's options in ICS. For reference I'm currently running Jedi Knight's latest rom.
I have attached a picture of my cpu usage while at my home screen. The number I've read to be average loads, and anything over 1.00 means trouble. I'm consistently over 10 for my one, five, and fifteen minutes averages. Also, my red bar which apparently measures time in kernel, sometimes spikes and correlates with a brief moment of unresponsiveness.
I've only seen two other screenshots and both users were under two. I was curious what everyone else's loads were. Also, let me know how frequent you have brief freezes, what kind of background apps you usually run. Include info like how many activities do you allow to run in background, do you force gpu rendering, etc. I can't wait to see other's results.

That's normal. The only roms I know that work 100% smooth are Jelly Bean Roms on OFFICIALLY supported devices like the Nexus S and Galaxy Nexus. (Yes the Nexus S runs smoother than this phone. Not faster, smoother) but what OP is stating isn't normal in the least bit. My advice? Ditch that rom. I've never experienced such high CPU activity on any rom and its bad news. Your phone will eventually overheat and shut down. Never a good thing when the SoC gets no form of cooling.

I was also thinking that it could be calibrated differently somehow. Like, if it was off by a factor of ten. My values would be much more reasonable. But I have seem several screenshots in the 1.0 range.

Min has always been in the area of 9/9/10ish. My screen has never stuttered not even on GB, no rrs or sods on official cm10 so far either. My battery life is an entire day (16hrs) of listening to music/playing emulators nonstop.
Make sure you have the 2 idle processes in your battery. If you don't then your phone doesn't idle which will kill your battery life.
If you are using cwm non-touch make sure you use dark side tools or upgrade to touch recovery (cwm 6.x.x.x or TWRP... my favorite). Reinstall your ROM with a complete wipe, install gapps, boot it up then wait 10 mins before doing any setup.
If you are idling then look at your batt stats again... screen is probably waaaay up there... play with your brightness settings.
Hope this helped

Nope cpu spy shows how much time the phone is in different mhz.. like if you turn off your screen it will go into deepsleep and when you open the app it indicates how much time the phone has spent into deep sleep...

holy sh*t the android system is raping your battery, well I love wicked roms(ICS) awesome battery and super smooth. You can also check out FrostyICS and FrostyJB those are also really good ROM's. I personally like ICS ROM's as they are more stable and don't have minor issues that some the JB ROM's have.
Check out post #3112 and #3113 in the WickedV7 thread and check out the battery life pic people posted on that ROM.
GO to the Play store and download no-frills CPU control or set cpu and check and see what you Min and max is for your CPU.
I have an extended battery and after 4 hours i was at 65 or 70% which is way off!!! I check this and it showed that my min and max was at 1024 once I changed the min to 384 everything got better

When it comes to battery life, there are many thing that you can do to improve it.
First off, turn autobrightness off, and try and keep the brightness slider as low as comfortably possible.
Dark, if not completely black background are not only sick looking, but they help with your battery life.
Less widgets, especially ones that require frequent updates...like weather widgets, and facebook widgets will wake
your system up to update. I suggest removing most, if not all of your widgets from your home screens.
Download an app like setcpu, nstools, or voltage control to set your min and max frequencies. In setcpu, make some profiles for screen off to
make sure your system isn't throttling up while your phone is not in use.
Change your governor and i/o schedulers. With a high end device like this, you can comfortably sit on conservative governor without experiencing bad lag...i/o schedulars wont effect battery life too too much but simple ones are best (like sio).
Run v6 super charger, kickass kernalizer, and 3 script to improve the way your device runs, and battery life. Stick to wifi when possible. Having low signal will cause your phone to constantly look for a better signal which will prevent it from deep sleeping.
Use titanium backup to freeze unnecessary processes, such as DRM protected content.
Download one powerguard to help also.
Good luck!

This was mentioned in another thread. DL this app: https://play.google.com/store/apps/details?id=com.eugene373.cpu.sleep
It shuts down one of your cores when the phone isn't in use.
Also DL CPUspy. This will show you exactly how often your phone is using certain frequencies, and whether or not it's going into deep sleep.
It looks from your screenshot however that your standby battery is not the problem, it seems to shoot down when in use (at least I'm assuming that was from when you were using the device).
Click on "System" and take a screenshot so we can see what's going on
Sent from my SGH-T999 using xda app-developers app
Error is the first thing listed. Have you tested the battery by doing a full reset and flash, then not installing any apps? If this is happening across roms and builds its most likely one of your apps not playing well with the system.
Before your next flash, go into dev options and turn on Show CPU Usage. Then let us know what processes seem to stay at the top all the time.
Also get cpu spy from the market and after letting it collect its data for a while (especially when not using the phone) check it to make sure its going into deep sleep.
After those two, do your clean flash and run without installing any apps for a while. Then when you do install them, do not restore from a backup. Download them fresh from the market. Also do not restore any backed up data, at least at first.
When you do flash your system, download the full firmware to your computer (use root66 if you want to keep root). From recovery choose format data, this will wipe your internal sdcard, btw.
Now boot into download mode and using Odin, flash the firmware you just downloaded.
Once done charge back to 100% and see how it goes.
You can get the firmware from my stickied thread in development.

As long as you follow instructions, and make sure you have the correct fw for your model, Odin is actually quite easy to use.
Restoring apps and especially data can cause all kinds of issues when jumping between different builds and especially android versions. The updated apos and system often have different database structures, different data files, and even different storage locations sometimes.
I'm betting this is where the problem will be.
I understand not wanting to go through all that I mentioned, but if you want to know where the problem originates, you have to start removing variables to narrow it down.
If you don't care what's causing it, jump to the flash. Nandroid backup, wipe everything, odin flash, test. If all is well, restore the data part of nandroid. If problems start again then you know its either your apps or data causing the problem.
Odin instructions are in TheExels thread stickied in this section.

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.

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?

I doubt that would be the issue. You haven't changed anything else ? Such as OC'ing higher, or at all ? Switching Kernels ? Dropping the Device ?

Nein.
Some info:
Any ROM.
Always using stock kernel.
No tweaks.
have you downloaded any apps? they might be making your cpu work harder...
I like to run my setup for a day before I download any apps, so no.
I've also wiped internal storage.

this is very strange. but you have flashed a new rom correct? that may be your issue... some roms come pre oc'd and not all phones can handle it

What Rom are you running ? What Kernel ? What are your Min / Max settings for the Kernel ? Voltages ?

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.
Just curious if anyone else is getting extremely slow performance? I'm running CM10.1 and it is slow -- one of the last stable builds.
I've found that I can't have Hangouts + Facebook or Hangouts + Chrome open at the same time. It'll take ages to load something, so I end up having to force close everything pretty often. And my phone's battery is getting worse and worse in terms of performance
Have been debating what the cause could be. I have a TON of music on my external_sd -- wondering if maybe Android is constantly scanning it and it's slow/losing battery from that. The media scanning icon is not up, though. Could be the ROM? Have been debating dropping back to using a deodexed/debloated stock ROM. Wondering if maybe the battery is just naturally degrading -- I've had the phone for ALMOST one year. Wondering if it's the issue with just having 1GB of RAM on the device?
Any thoughts from anyone on improving performance? I would love to be able to go to work without having to charge the phone. I can go for about 8 hours at work (sometimes listening to music, sometimes not) and by the time I'm home, my phone is anywhere from 10-20%.

as I know media scan only runs after boot.
Most of android devices has less then 1 giga ram, I don think you need more. You can enable comcache. settings -> performance -> memory management -> zram , it needs kernel support.
zram compresses memory.
My 4.3 roms dont have zram support.
Factory reset always win. You should try latest cm10.2, I think 4.3 faster.

Wait, so the newest pacman doesn't have zram support? Is in the settings though.

kernel doesnt have zram.
Zram and other improvements
Hello, good afternoon to all
First, sorry to revive an old post, but i can't post in dev zone.
I am currently improving the performance of my i927.
I installed the kernel "LiteKernel" (V4.0-20130113 ICS) but I have some doubts. For example, how I can enable zram? How I can make a small OC the GPU?
I would appreciate some more advice.
Stock ICS 4.0.4 ROM UCLJ3 with LiteKernel ICS V4.0-20130113
Thanks a lot!
Try with trickster mod

Thanks a lot!
zRam activated and working, and see that GPU is on 400mHz always
But i was thinking in app like Android Tuner that can set a boot profile... because i have to enable zRam every boot
Any idea? any other improvement?
THANKS!
EDIT: Now i see the option that i can set a profile when boot with trickster mod!! thanks again!
