This might not seem like a big deal for most, but I myself listen to music with my phone for at least a couple hours a day. After reading a post by pchemerys on how to save battery life (which everyone should read, a lot of good information there) I decided to play around with the voltages trying to get as much battery life as I could. As a result, I noticed a ton of random clicks and pops in my MP3's.
After further investigating, and going back to default values using Ktweaker (stock voltages), the problem was still there.
What fixed it? If your minimal cpu value is at 96Mhz, that is when the problem occurs. I adjusted that incrementally until the music was clean again, and my minimal cpu value is now 192Mhz.
Thats all you have to do. My min/max values are 192/1512
Hope this helps my fellow xda members!

yep, 96 was too low for me for a few things as well.
192 still doesn't fit it for me, but I was undervolting. It's a matter of voltage + cpu.
Yeah my phone is very fussy when it comes to any tweaking. I can't go below 384 and I can barely under volt with out any without the audio issues. Kinda sucks

Pretty much same here, seems like there's a wide variety in chip robustness on these. I can under volt everything about 50mV from stock, but my min can be no lower than 384, even with stock voltages. Any lower and I constantly get reboots and other issues with pretty much any governor

That's weird. I don't get reboots below 384 just the annoying sounds in music. Its frustrating to say the least

I'm having trouble finding a CPU app that works perfectly with this phone. I've tried setcpu, CPU master, system tuner, and nstools. What's everyone using to oc this thing?

Depends on which rom your running but in general...you should use none. Most roms already uv and oc and if u use an app it'll butt heads.

My issue is that it seems like my phone is skipping steps all over the place. I'm using cpuspy and the usage jumps between Max/min clocks. I'm kinda not digging that. Its the same with every rom i flash.

That's not an issue with your cpu app. It has to do with your governor (the thing that controls how your CPU scales). Most ROMs come with ondemand by default which pretty much does exactly that, which is jump from min to max as needed. If you want something that scales more, you should look at conservative (for better battery life) or lagfree/interactive (for better performance). Lagfree/interactive are only available on select kernels though (whereas conservative is almost universally available). Streamline definitely has them and I think synergy does too.
Also CPU apps don't butt heads with the ROM/kernel default settings, it just overrides the default settings.
Yea I figured that but this is the first phone I've had where on demand performs that way. I've had a nexus s, epic 4g, evo, and a g2 and they all scaled across the steps ondemand. Ondemand on this phone works like the min/max governor. But your right conservative scales across the steps well. Just a bit choppier. About to install nstools and mess with the threshholds and whatnot.

I am running stock ICS, with the cpu sleeper app running and my "awake" time is crazy high. I use to have awesome battery life pre ICS, oh and I forgot to mention that I have the nexus extended battery what is running and how can I kill it....I use to get around 19 to 25+ hours before zero now I don't. I have tried to celebrate the battery by letting it run to zero, wiping battery stats and having it charge up to 100% powered off and it still suck. What am I doing wrong? Also I enclosed a pic of my current battery stats for all to see

I suggest getting GSam battery monitor and seeing what is killing your battery. If you really want improvement root that bad boy and gets your self a custom ROM!
Here is my battery life, typical day. AOKP 7/15 with latest CPU sleeper.

Have you looked through the battery stats list of what been running to try and track it down that way? I've also hers people say if your using google voice and restored it from a backup that it will cause wake lock. Uninstall and reinstall from the market if that's the case.

Also try out CPU Sleeper: http://forum.xda-developers.com/showthread.php?t=1745516
This is also hosted in google play.
Description of the badass governor:
Badass removes all of this "fast peaking" to the max frequency. On a typical system the cpu won't go above 918Mhz and therefore stay cool and will use less power. To trigger a frequency increase, the system must run a bit @ 918Mhz with high load, then the frequency is bumped to 1188Mhz. If that is still not enough the governor gives you full throttle. (this transition should not take longer than 2-5 seconds, depending on the load your system is experiencing)
Badass will also take the gpu load into consideration. If the gpu is moderately busy it will bypass the above check and clock the cpu with 1188Mhz. If the gpu is crushed under load, badass will lift the restrictions to the cpu.

Like the title states when listening to music with headphones plugged in I get sound crackles.
It doesn't matter if it's through Bluetooth or the jack. When listening on external phone speaker it sounds normal. Or when I use headphones for phone calls there is no crackle. What is going on?? I'm on jelly bean currently but even on ics same thing happens.
Can anyone help me out? Is there a special app I need or do I need to do something in the settings. It's driving me nuts.
Sent from my SGH-I747 using xda premium
Also I have noticed that if chose different cpu governors and different I/O schedulers, I will have less or more crackles. Does anyone know the best combo for sound quality?
Or I should be doing something else.

Had this problem on my first handset... Read all the similar issues, and eventually got it replaced. New one is perfect on Headphones, built in speaker, and both of my bluetooth systems.
Call for a replacement if you can.
If I switch the cpu governor to "performance" the crackling is almost non existent. Does that still warrant getting a replacement?
I got this phone the day it came out so I am past the 30 day exchange.

What kernel are you running? Some have reported that if your min cpu is below the stock 384Mhz these problems will arise. Also experianced this when undervolting.

That's odd. I'm running the same with no issues.
Try bumping it up, it doesnt hurt. Do you have a screen off profile enabled? Turn that off as well. If I'm lower then min 384 and listen to music my phone soft boots all the time.
Remember, your min is not that important. Whats important is that your phone is going to deep sleep.
Hope that helps

No I haven't messed around with the screen off profiles. Could it be the kernel?? I don't see why it would be, maybe I'll ask in the kernel forum.
My phone goes into deep sleep, but the music crackling happens even when I'm using the phone. The weird part is it only happens with music...
Other than that the phone is a beast. I really don't wanna deal with the hassle of replacing phones.

Hello
I'm currently using a note2core asylum kernel which supports both cpu and gpu overclocking. My question is, how do I go about overclocking the gpu? Any help will be appreciated.

I know. Its all for.research purposes anyway
Sent from my GT-N7100 using xda app-developers app
I'm not sure if note2core supports stweak but that's the app you need to over clock. There are other but I prefer this one. It will give you a maximum slide to 1800mhz and also tons of other features such as adjusting charging amp, under volting including for the gpu as well. There's not much to know about over clocking as its pretty straight forward but you can change the xpu governor and the number of cores you want activated and how you want them to activate based on your usage. Under volting will help with both temperature and battery life although I find the changes almost insignificant, but you should try it out. If you want to undervolt start with around - 25mv.

You are talking about cpu not gpu
Sent from my GT-N7100 using xda app-developers app
Okay it's not that different. Just over clock it and undervolt at the same time to - 25mv and then download an app called stabilitytest from play store. Run it for 10minutes and see if you get any error. If not then further lower the voltage to - 50mv. But usually - 25 is good. I noticed that anything higher clocks peed than 5xxmhz starts causing error and graphic glitches.

Sent from my GT-N7100 using xda app-developers app
I don't think there's much you can do with regards to battery life. I've tried doing what I could to get a good battery life with CM/aosp and the best I could get was 5.5hours screen on time on lowest brightness and 12hours between charges. Compared to stock I get 7-8hours screen time and 24+hours between each charge. There's nothing much you can do with battery life.
Sent from my GT-N7100 using xda app-developers app
You could flash a kernel like n.e.a.k kernel .. and download their app..
For getting a slightly better battery life, undervolt your CPU by 50-75 mV each step and you also may set the CPU ti 1.4Ghz instead of 1.6GHz
For the sound, using their app, there is an option for speakers and headphones.
Set speaker between 57 and 63(loudest) and same thing for headphones. .

Even with neak kernel or redpill undervolted it still sucks at battery performance. And sometimes under clocking to 1400mhz results in graphic glitches in the UI with aosp. I think its just not designed to manage battery usage as effectively as Stock ROMs.

The problem isn't in Google .. 4.2.2 works with great battery on nexus 4 .. cm can't be like google but they are trying to make the rom as battery efficient as possible
I personally get 5-6 hours of screen time..
I get 6-8 hours on touchwiz.
No big optimizations made.. 1600 MHz and UV 50-75 .. and overclocked GPU for better rendering without UI glitches ..
