Hi, first to defend myself, I did search and found that everybody says good things for every kernel. So every kernel is best for Stock ICS?
I got confused. Yes I'am total noob and recently learned how to root and flash custom rom's.
I just want to hear your opinion for best kernel running on Stock ICS.
I need kernel that is good for the battery but also snappy for the system. I don't play games and I use my phone for calls, reading news, working on excel files, google maps, mail and taking pictures.
My phone is Nexus S GT-I9020T on Wind network.
IMO ezekeel kernels
Has lats of featured including voodoo color

Thank you. Is this kernel stable?
Im just trying to set it up as we speak, will let you know how stable it appears once I figure it out
Stuck on trying to flash an unsecure boot image at the moment.
*shrugs* The stock kernel?
Unless you want the functions third party kernels bring to the table, I don't see a good enough reason to swap the stock kernel for another.
That's what I was thinking. With Glados kernel I had problems with restarting after the screen turns of, also with Matr1x kernel. Also I read that there are restarting issues with IMO ezekeel kernels. Yes I know that probably the most stable it's the stock kernel, but there is problem with battery, I had more juice with GB and CMD 7. That's why Google paused ICS update on Nexus. But probably I will stick with Stock Kernel because for me it's better to have less battery for now instead random restarts. I hate when my phone it's not in perfect state.
Just managed to get ezekeels CFS on there and I get the reboot bug after going to standby.
Looking for updates but the thread is huge. Yet to try BFS.

You can try and turn off deep idle for your reboots.
Solves the problem 99% of the time (totally made up stat that could actually be true)
But actualy that function (deep idle) it's the most impotant thing in the kernel. It gives more battery time. Other thing are just fancy. More battery and no hickups, I dont need overclocking because I dont play games.

Deep idle gives more battery time under certain conditions (screen off but not completely idle, playing music for instance). It won't really give you more battery time if your phone is actually idle with the screen off.
But according to this http://forum.xda-developers.com/showthread.php?t=1297535 I understood differently. Maybe you are right, I'am still noob to all of this.

The first post that you linked actually just confirms what I said.
Ezekeel said:
Since this is just theory and Morfic noted that his experience seems to indicate otherwise and that limiting the CPU frequency does actually decrease the battery drain, I put this theory to the test and logged the battery charge over 10h of FLAC playback in Airplane mode with the screen switched off.

1) Playing FLAC (not idle)
2) Screen off
Pre-requisites are met.
So as I understood the battery consumption is reduced only if you listen music, because you can't do anything else when the screen is off. And the deep idle is working only in standby mode (screen off).

Deep idle only shows savings if there is tasks running while the screen is off VS the same situation without deep idle.
So for someone doing commuting (like simms22 for example) and listening to music for around an hour, they'll lose less battery with deep idle than without.
You won't actually save battery if your phone is actually idle with deep idle enabled.
It's not some kind of magical function that makes your phone use less battery doing tasks with the screen on, deep idle disables certain components of the phone while executing tasks with the screen off, instead of having it "at full speed" as if the screen was on.
Now I understood. Thank you very much.

No problem. I think Deep Idle is probably the mod by Ezekeel surrounded by the most misconceptions.
Most new users want it absolutely but don't seem to know why.
On His Glados kernel I noticed that Android OS was using 20%-21% of the battery and on the stock kernel 30%-31%.
Android System was using around 14% and on the stock around 19%.
Ok, have you decided to give the Glados 2.2 another go? I believe I have finally tweaked it so that it is stable for me.
Before I was getting restarts within 30 seconds of the screen turning off. I have cornered this (on my phone at least) to a problem with NSTools auto-setting the lower frequency to 100mhz. Changing it back to 200mhz and I have yet to see the system restart itself. Im not overclocked, because I dont see the point as everything is fairly snappy with this new kernel. I dont really play games on it so Im not fussed.
I did used NSTools and the frequency was set to 200mhz and I had system restarting on screen off. Using stock ICS with Glados 2.2
Also I had green annoying flickr on locking and unlocking the screen.
Hi,
First post, be kind, I'm just wondering if you can use a Kernel such as Matr1x with the newly released ICS 4.0.4 stock rom ?
I still think battery life on this is pretty bad - I'm thinking this could make a difference if possible to do.
If you have any hints / ideas - would be most welcome.
It's driving me crazy - a charge over night then a charge about 3pm ... I think is a little excessive.
My phone is rooted.
Thanks to you people
Yes you can. download the kernel, reboot into recovery, wipe dalvik cache and then flash the kernel

Maybe. I didnt try matrix kernel 18.5. But the chance that the battery life increases is very high. Also depends on your usage.
And your welcome

Thanks for confirming what I thought would be a good call to use the Matr1x Kernel
Its a newer kernel base .26 vs .22 on the kernel your running the main reason I changed to 18.5 is swap was taken out and fast charge was added.. if neither of those matter to you I don't think there's any huge differences...

I shall see how I go with the 17.5, easy to change round ... cheers for your comments.
The ability to change your governors and IO schedulers should help battery life.
I've been using the combo for a bit over a day now and the battery is pretty great when on WiFi. About 5-7% per hour of screen on time and playing games like Temple Run or Boost 2
It will help! Use the CFS version. That tends to be a bit more stable. next, get and app called NStools. Set your min speed to 200, and max to 800. Then set the liveOC to 105. On the first page at the bottom tap it and pick noop. Set govorner to smartassV2.
I get a day and half with this setup (On CNA 1.6)

Set LiveOC to 100% or raise the voltages. Do the former if you havn't played with voltages before.

Are you using the stock charger? mine does the same thing if I plug it into a blackberry charger.
May I suggest getting a stand alone battery charger and an extra battery or two and then you will never have to plug the charger into your phone again.

All this for extended battery life!! Yes using the stock charger ... frustrating because it seems to go unstable when the power goes in... I have to take charger out before it will come back alive!

I have GT p6200 running Carbon ROM KitKat 4.4.4
And since I updated room ICS I've been having this overheating problem
When I was on ICS the tablet didnt get hot while using WiFi
But when I moved to KitKat I started facing this problem
But if it's not the WiFi could it be the CPU governor ??
Now mine is set on user space
If so what's the default CPU settings for this ROM
Thnx

Since I updated to KitKat 4.4.4 carbon ROM
I've been facing battery drain while using WiFi mostly not during sleep
I tried doing everything I could to stop it
Disabling Google play services from time to time... Using greenify
Freeing up ram ...battery saving mode
Disabling wake up for apps from app ops
Now I use it for 2 hours and it uses 40 percent of the battery with the lowest brightness though
Please give me suggestions or fixes

Sometimes when I turn on WiFi it get stuck and totally freeze until I reboot the device
Is there a way to fix this
And I use xposed modules by the way
Could they have an affect ?
I only use greenify, clear recent apps, clipboard and XAD modules

Post 3 Default CPU governor settings for this ROM is on demand
Looking at Post 1 & 3 Both of these have to do with the battery Heat
overclocking generates more heat but under-clocking generates less heat (i have not extensively used this feature but asking in the dev forum or if Google'd the governor settings of the ROM might help to see what it does)
high battery temp you less battery capacity e.g 4 amp becomes 3.2 amp BUT low battery temp more battery capacity e.g 4 amp becomes 4.8 amp
also motherboards like to be cool 50 degrees F to 95 degrees F or 10 degrees C to 35 degrees C this is the ideal working temp
anything more or less than that would cause a waste of either performance and/or battery capacity
my tab has worked from 11 degrees through all the way to 60 degrees C battery temp please note i live in South Africa i go to cold places and it gets really hot some times so use these values as only a rough indication
my tabs idle temp is 15 to 25 light work 25 to 35 gaming 35 to 40 degrees C this is a thumb suck of my normal temp can be more or less (just pulled my tab out of my pocket 23 degrees C and while typing this sentence increased to 24 degrees C currently it is 8 degrees C 81% humidity inside a building )
can i ask that you post your battery temp? as temp is relative (i am using antutu benchmark x widget that displays temp and batterylogger)
also the heat could/maybe be causing your WiFi to get suck not on or off
please see it changing the govenor fixes this
hello,
I would like to know what is the best rom for my idol 3
With the stock rom I have a lot of lag and with CM+Arde kernel it smooth but I have a very high battery drain even my charger don't charge fast enough when I use it, also it gets very hot.
I have the 6045i Canadian.

Hello, I think AICP is the best ( [6045x][unofficial][5.1.1][08.01.2016.] aicp 10.0 ),because its simple, just try it !

Hi I'll try it I love simple rom KIS. I changed my governor to interactive, it was on performance. I'll se if there is an improvement. Phone runs colder but I don't see any improvement in battery life for now.
OK, I ran into this issue about 5 days ago. No matter what ROM I install, my phone constantly heats up within 15-20 mins of casual usage. I don't even play games on my phone. I tried N ROMs and MM ROMs too, no matter what ROM I install, phone just heats up. I'm attaching a screenshot from CPU-Z app (which I used to monitor the temperature). Are those readings OK, or is there something wrong with my phone?
My phone's temperatures are usually similar to yours and I thought this was normal. In case it's not I'd like to see a solution to this as well.
Btw, do you have any custom kernels? Agni made my phone way too hot..

I don't really go for custom kernels unless I'm testing one. I stick to the kernel that comes with the ROM.

I have checked. They are mostly around 800 MHz mark. And 45% of the time in deep sleep or 400 MHz.
Also I want to whether surrounding temperature can affect the values? Right now the temperature at my home city is averaging around 34-35°C. Would that be the cause?

Not to hijack the thread but I have experienced all the cores being on max. frequency. I noticed this when my phone started warming up even being idle.
I saw this behavior for a few times in RR with both Optimus and Firekernel (Optimus had optimus set as its governor and Firekernel had darkness), however never encountered it in Ultradevs (with both chill and darkness).
This was a couple of months ago, and it hasn't happened again yet. However I am not sure if this was related to kernel because sometimes force stopping random applications such as greenify or nova launcher made the frequency scale down back to 400 (efficiency profile). Unfortunately I didn't get a hold on what was causing this, but I suspect some background user application was the culprit.

I also faced this issue first time when I flashed RR 5.8.2, no custom kernel used. And now its following on every ROM I install. I even tried custom kernels, different gapps packages but none seem to work. The phone heats up while charging and while doing simple things like using WhatsApp, sending emails, browsing through XDA. Also kernel adiutor is showing that GPU temperature is always above 43°C.

Did you restore apps through some backup program such as Titanium backup? In my case, I used to use it and it might be the reason the problem was popping up everywhere.
If not, and if the phone still heats up even in clean state (after a fresh custom/stock rom install), then maybe some hardware issue could be the reason.
My Cpu-z reports battery being at 37° discharging and the sensor0 to sensor5 show 45-51°c although the phone feels way cooler than that.

yeah, thinking you may have to flash stock, not restore it via twrp. I know it's a pain but it would give you a good reference point.
Well I can't flash stock ROM for the next 2 days. So let me ask this : Is a temperature of 37-42°C for battery and CPU harmful for the phone? Or I shouldn't worry about it?
107F? I shouldn't think so...
"Right now the temperature at my home city is averaging around 34-35°C. Would that be the cause? " It wouldn't help...
I am 26 ambient and my phone temps run 36-36 or so.
Ambient temp does play a factor. If the phone is Almost as hot as the ambient it's hard to transfer the phone heat to the ambient surrounding.
My freqs and temps in attachment. I use aosp-caf with prepackaged kernel(ud i think) with some custom settings.
Ambient temp is around 20 C inside and 10 C outside

Thanks a lot. Even when my phone was not heating up, the CPU and battery never got cooler 31°C. And GPU was around 38°C. And even after intensive use, CPU never got hotter than 37°C.
Now my phone's CPU and battery are around 35°C mark and GPU around 43°C. And during use CPU reaches 43°C mark and GPU about 52°C. Can these temperatures cause any harm to the device?

I have not faced any issues since I am using Nano Gapps. Previousely I used Mini gapps and that was causing the issue . Depend whar Mobile you use 1GB RAM or 2GB RAM. Also it is better to clear cache after every install
Also I use following settings to make suer it doe snot get hot.
-Ambient Display Off
-Adaptive Display Off
-Try not to block any apps from sending notoification as I had issues where battery draining and mobiel heating up by doing so
-Keep brightness to minimum

Thanks for replying but its not the issue of any ROM. I flashed stock and the issue still persisted. So I literally contacted everyone I know of who owns an unrooted osprey in my city and asked them about this.
Turns out everyone's phone is getting hotter a lot faster than before. Even went into a Moto Service Centre, they said its fine for the phone to heat up in such temperatures.
The issue is ambient heat. As you might have seen in my previous post, I mentioned that the temperature in my city is averaging around 35-36°C (Today it reached 40°C), the phone just doesn't cool down enough after using it. So when I started to use it again, it heated up.
