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.

I've always read in the past that the app doesnt actually help with battery life because its purpose was for OCing and Android regulates the cpu clocks already.
So I'm wondering, for those currently using it, have you noticed any difference in battery life (without underclocking while in use)? and if so what profiles are you using?

Android does regulate the cpu, but I don't think it will take advantage of more conservative governor modes unless you tell it to. That's only relevant if the kernel supports more conservative governor modes. And, as the other responses have pointed out, you can force Android to be more conservative by capping the max clock speed.
Hmm... Guess its worth a shot. Good lookin out guys.
when i go into setcpu there are alot of options to choose there is no auto detect like on my mytouch 4g. how did you guys get it to work. i picked the last option which was custom and it forced close on me.

I think that that means that the kernel is not supported for the "automatic" governors. However, you can still create profiles to regulate the CPU based on perameters that you set, i.e. Screen off 216/216

So all G2x see the same in setcpu - no autodetect and only governor available is "driver"?
Will custom ROMs like CM7 change this?
SetCPU improved my battery life tremendously! Before I was losing about 15-30% and hour, since 8:30 this morning my battery only dropped to 73%. I set my active profile between 457mhz and 816mhz depending on remaining battery and it's still fast as hell.

Once we get some custom kernels, we should be able to change the governors in setCPU, dependent upon on what the kernel supports.
SetCPU Custom Frequencies for G2X
I got SetCPU today and was playing around with it and it looked like it was limiting my CPU all the time due to lack of profile, not just when I had the screen off per my profile so I looked into making a text file for custom frequencies and am posting it here since there doesn't seem to be any help for g2x with it.
This is a really simple file, tell me if you guys have any better ideas, I just put in:
216000,528000,712400,1000000
I'm attaching it. I put the file in my dropbox, grabbed it via the app and then moved it to /sdcard/setcpu.txt via astro file manager then loaded custom profile from within setcpu. Hopefully this saves someone some time or you can tell me if I'm going about this the wrong way
I'm sure it could be fine tuned more but I was getting irritated at how much of a pain it was to unlock the phone with it set too low, so for screen off I have it set to 216->528. You could add 254000 in or something. The phone seems to be as usable as before now with setcpu enabled like this while it should be limiting the cpu when the screen is off. It sucked (well not the battery) without a custom profile.

Actually, your assumption is wrong, as is often the case.
I'd quantify it more as normal use. Lots of texts, some games of Pro pool, a few phone calls, checking Pulse 3-4 times during the day for 10 minutes at a time, some mild web browsing and watching a few youtube videos.
I ended up at around 18-19 hours of of use.
Today, I'm off the charger for 8 hours, and I still have 45% left, and I would say that's with some moderate to heavy use.

Try upping it to 216/312 or a tad higher and you should be fine.

The battery life is a lot better now with the latest builds of CM7 and MIUI.
I just use CM7 and leave wifi and bluetooth off, no juice defender or anything like that and I can easily go all day with no charge, typically about a day and a half and my battery is getting low but it really depends on what you are doing like games, wifi, videos and whatnot.
Before I think there was a problem with the battery draining while in idle but things have cleared up since then, There are also third party kernels you can OC and everything, but you can use them to undervolt as well to save some battery if you know what you are doing. over on androidforums there is a lot more chatter about this phone, just so you know.

Thanks. I got my phone today and im loving it so far. Do you know which of those third party kernels are good for battery life and that i can install over stock? I'm not quite ready to install a ROM yet but i already did the HTC Thunderbolt Build.prop tweak and obviously im rooted.
It's usually not the kernel but whatever governor you have it set to use. Even the stock can get improved performance if you switch the governor to such--”performance”--but I'm probably not the guy to tell you about which one is best.
I also have the silly feeling a lot of misconceptions abound here...in the form of ”I changed this setting and now my device lasts longer..., oh btw I no longer play with it 24/7.” In other words, use drastically impacts battery performance. JuiceDefender is an amazing tool but it won't do you a bit of good if you're testing out your phone's Adobe Flash capabilities regularly.

The Savagezen and interactive (not sure if interactive is on any of the kernels for this phone.) gov isn't that great. At least not in my experience. I had SmartassV2 on my girlfriends phone and it got ~3600 on Antutu benchmark at 1.5 and when I used Savage at 1.5 she got ~1700. The interactive gov made my friends Dinc2 noticably slower. Just switching home screens it lagged to the point it was hard to get into the app to change the gov.
CM7 + TheOC kernel allows adjusting voltage & overclock or underclock. You really should flash a CM7 ROM. Having it just rooted can be dangerous because you're not using a custom recovery to make a backup image, and if something messes up, you don't have a backup ROM to restore. Going to a different ROM forces you to make a backup, then there's a backup to restore if you mess things up.
Governors just tell the CPU how fast to ramp up to a certain frequency, & how long to stay there. It's hard to balance fast ramp up (less lag), and low battery drain (spend more time in the lower frequencies). I like interactive/x, find that smartassv2 spends too much time in the mid frequencies (~500) even for light work. Using the app CPU Spy helps a lot to see what's going on. Also it tells you whether your phone is sleeping properly when screen is off, which is a big factor for battery drain.
Hey XDA,

if you just booted, it should(for about 2-4 minutes) then it should drop. unless you have an active live wallpaper, an app thats not written very well, or a process thats gone wild. try that app i linked, let it run for a few hours, maybe you can find the cause.
My phone had been on for a few hours...
Also, I flashed TEUV, and I don't think my phone handles it very well (TEUV has GPU overclock). Once I booted, it gave me a black screen and said: (Application) has stopped working for every app on startup. This happened twice, so I went back to Matr1x and battery is still terrible...

sounds like a bad download of teuv.
Bad download? I flashed it properly and it booted fine, until after the "optimizing applications" screen
is this the first charge since you flash the kernel? If it is, let the battery run out, charge it full and take a look at it again. I find that ICS really take a full charge to stablize its battery... my first charge after flashing a new kernel has always use a lot more battery than the second charge.
Alright, I'll try that... Also I went back to aosp+ because I really like it.
Also, android system is always using 20% cpu, even on idle..
I remember performing some tests with frequencies and deep idle - I wanted to find out the minimum frequency required to run music player screen-off with few concurrent processes. I remember reading how 400mhz is the optimal frequency for deep idle but cpu spy would always report it cruising at 1ghz and cross referenced with nstools DI stats, it was supposedly in deep idle. With DI off and bumping up the frequency to 800mhz, 1ghz took up the majority of operation time. Long story short, whatever combination I tested did not garner desirable results. That was a couple weeks ago, though. I've since given up on figuring it out.
Wait, are you having the same problem as me?Ive lost 5% battry just by having the screen on for 9 minutes...
I just got upgraded from CM 9 stable to CM 10 stable and I love it. Only problem is battery life. I feel about a 10-15% reduction with the new upgrade. I've had CM 10 for about 4 days now.

Don't worry about changing the cpu and governor settings. There is an option to set at boot. Make sure that is disabled, so if you have any problems a reboot will go back to default settings. I use the conservative governor, and have my minimum cpu speed set to 192. I've read that that speed is not entirely stable for many people, but seems to be working fine for me. That has been pretty good for battery life for me. I believe the default governor is interactive now, and the minimum cpu speed is set to 384 by default.
Do you just "feel" a battery difference, or do you have any actual numbers to back up that assertion? Keep a close eye on Settings / Battery and use Better Battery Stats to record solid numbers and identify what's actually eating your battery.
Also turn off google now location settings if ur not using it. They are really hard on the battery.

It seems to be my screen that is responsible for eating up my battery.

I have the automatic brightness setting off and put my setting at pretty low.
The cell stand-by battery usage is 8% during these 4 hours. Should I maybe try another radio or is this normal? It lost signal for about 10 min today.
Just turned off google now and selected the conservative governor. Let's see if this makes a difference.

Thank you for all your help
That's most definitely not normal, at least in my experience. Are you using the vanilla CM10 or some variant?
Some things to try:
Install Better Battery Stats (find the free version on XDA via a search) to see if any apps are causing wakelocks. This is a must.
Use CPU Spy or something similar to see if your phone is entering Deep Sleep. This is a must.
Turn off Google Now unless you actually use it
Turn off all unnecessary radios (WiFi, Bluetooth, GPS) unless you're actually using them
Turn off all auto-refresh settings in every app you have -- all social apps and weather are the biggies
For me, turning off the default auto-refresh in Facebook, Google+ and Twitter are massive savings alone, then Settings / Battery & BBS will help you locate the remainder of the headaches quite easily.
You might want to consider swapping kernels too, or at the very least reconsider your CPU governor and scheduler settings.
I would stay away from conservative governor you won't get much performance out of that, stick with what comes stock and use on demand.... even the default interactive sucks my battery down

Turned off google now location access and set the govern to on demand early this morning and it is performing a little better most def.
I have noticed that my phone lost signal 4 times during the day for periods varying 5-10 min. I am currently on the I727UCLF6 radio. I'm thinking maybe I should try another one. Could that help with that battery maybe?
I have been thinking about switching kernels but I am a little doubtful because I don't want to mess up my phone too much since I so heavily depend on it. I loved the hotcakez kernel that came with AOCP, maybe i'll give it a shot this weekend.

Just do a nandroid backup of the entire phone first before installing a new kernel and your risk drops to zero. If you install it and it all goes to hell, just boot back into recovery and restore your backup.
As for radio ... if you drop signal that often and your phone is constantly searching for one, I suppose that could impact the battery, sure. Are you certain you're in an area with solid coverage, though?

Yea I might have to play around with some kernels this weekend. Luckily it is a long weekend so I'll have some time if I mess up
My phone will go from 4 bars and a good signal at -78 dBM in my apartment and then randomly I'll lose signal for abut 5-10 minutes. A restart usually does the trick or I can just wait until it regains the signal which can be frustrating. I never had any problems with my signal at home running CM 10 so that leads me to think that there might be some problems with the radio.
Just want to confirm that these are the 5 radios I can use for AT&T even though I'm running JB.

I've been using a UCLI3 modem I found on XDA a couple of weeks ago, it has been incredibly stable and strong for me. But as many people far wiser than me have said elsewhere, everyone's mileage with radios varies and it really just takes some testing to see what works best for you.
so I should be able to run the 5 ICS radios I found eventho im running jb right?
thanks for your help

This is not for the faint of heart.....
I flashed Clemsyns 1.9 Ghz kernel this morning and it has cut boot times down by about 15s, I am able to cold boot in less than 30s. I know this kernel isnt working for everyone, however, just thought Id mention it is working very well for me so far. Didnt need it for lag as that was gone with the 1.5-1.8 kernel, but it is worth it for the boot improvement, which was my only gripe with this device. In a truly mobile productivity device boot times SHOULD be less than 30s.
Will report later today after more stress tests and temperature checks.
Oh ya, I am running CleanROM Inheritance 3.0.4, fsync disabled, scroll cache disabled, and force GPU rendering.
Cant wait to see how this flies after Data2SD Mod (cant apply until i get back home to Halifax - East coast represent)
Best of luck

Just finished stressing the machine quite hard, everything is stable so far, temperature hasnt gone up at all either
Just thought id mention.....
GOT A SCORE OF 7524 IN QUADRANT.....BEAST MOOOOOODE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
MUUUAAHAHAHAHAHAHAHAAH! I VILL TAKE OVER ZE VOOOOOORLD
LOL okay let's see how much this drains on your battery!
Preferably show battery screenshots instead of just words

Good call, I forgot that most ppl would be interested in the battery drain.
I was fully charged before flashing new kernel, I have used for over 4 hrs, been doing heavy browsing, stress tests, and benchmark tests....all in performance mode.....im at 67% dock, 76% tablet...I keep screen brightness around 20%-25%. Havent noticed any more drain than usual.
Ran a benchmark test in balanced mode and got the same results as I used to get with 1.5-1.8 Ghz/700 GPU kernel....if you are worried about stressing your system leave it in balanced and switch to performance mode when needed.
Troo that overclock to 1.9 is a battery killer.
Have to say I didn't stay on it very long

That sucks I havent seen much of a battery hit at all. For the past 2 hrs ive left it in balanced mode and there is no diff b/w 1.5-1.8 kernel at 1450mV. I didnt use the 1400 mV kernel for very long bc i didnt notice any battery improvement, maybe the 1400 mV kernel is much better, are you using 1400 mV kernel?
Ive been using my tab for 5 hrs in performance and 2 hrs in balanced and im still at 33% dock and 87% tablet. Thats essentially the same as it used to be, should get at least get a full day of heavy use, especially considering I have been running stress tests, benchmarks, and repeated cold boots to make sure its up to snuff.
The screen and wifi are the biggest battery consumers, overclocking from 1.5-1.8 to 1.9 shouldnt hit battery too much.
maybe
maybe the 1.9 isnt kicking in, maybe try playing some shadowgun or something to see ur battery time,

I dont have any games. Games are cool, I just dont play them, and will never put a game on my tablet lol. I really cant say how battery would be affected by this kernel when gaming.
You might be wondering why I even bother with this kernel if I do not game. Well, my good sir, I happen to be a performance junkie, and cant stand lag of any sort lol. Multitasking is what i focus on, this tab has replaced all my other devices, and am happy to say my workflow is smoother and faster.
From my personal use I think the kernal rocks! I have used it before and just went to it again recently. The only reason I switched was because the Rom I used didnt have the option to install that Kernal and I was too lazy to flash it again. On a regular everyday use I keep it in balanced mode and really dont see a hit in battery. I personally only saw a little bit of battery drain in gaming however in the graphic and CPU heavy games there was battery drain anyways. I can deal with plugging it in more to get more performance out of my tab. I am one of those people that has 5 home screens, ones dedicated to all of my games and its fully filled with 6 different folders each containing atleast 10 more games. This would definitely slow down my tablet however with this Kernal its different. I also get around the same results in quadrant 7436 to be exact.I do see a temp increase but its not too large so I can deal with it.
Over all I think its the best Kernal out right now hands down.
Just curious - why do you even power-off your device to begin with? Normally, "mobile devices" are meant to be on always-on anyway, so I just don't see why the cold-boot time is such a big deal. The device goes into a deep-sleep state when in standby with very little power drain, which pretty much eliminates the need to constantly power off and back on the begin with.
Do you really completely power-off your device on a regular basis?
Again, just curious - obviously, that's completely up to you...
Personally, I only reboot my TF700 when flashing kernels and/or ROM's - otherwise it's always on. That way you never have to wait for it to boot!

I don't think the boot time has nothing to do with 1.8 or 1.9 kernel, my cold boot is about 22 sec. They should be about the same depended on how many app services you have running on your device.

I cold boot all the friggin time lol just my personal preference. It feels snappier after cold boot and I am constantly deleting stuff and trying new things/setups/setting configurations to eek out more performance, after each change I cold boot to get an accurate assessment of the changes that I have made. Lately ive been spending several hours a day trying to improve tab, which has meant a lot of cold boots. For the past few weeks ive spent more time optimizing and assessing this tab than acually using it, kind of nuts, i know lol, but i really enjot it and im off school right now and my hometown is in the middle of nowhere, less than 100 ppl live in my town lol. I normally shut down before bed, and do another cold boot after I finish classes around 7, boot time matters to me.
Oh and I will not charge this thing if it is on, I figure that draining the battery (no matter how little) while charging cant be good for its life long term.

I honestly dont know if it should or shouldnt, all i know is that i was booting in about 40s-45s before flashing 1.9 kernel, now i boot in 30s, Ive seen results by doing this. I time my boot times with stopwatch on my phone, i monitor everything going on in this tablet very heavily. Every time i change anything i like to be able to assess its overall impact on performance.
