[Q] Decks or Cm7's best kernel (SVZ vs Tiamat vs Godmode)

Hi guys, i've been looking into many threads and reading a lot of posts and asking a lot of questions. however i know that their is not for sure answer to this but i would like to see what you guys believe to be your best kernel for battery and performance. i have seen people say it is Godmode (v9), Tiamat v4.1.0, Tiamat v3.3.7, and Savaged-zen v2.2.1. (ALL of these ARE with SBC-OFF). i just want to know what is you best kernel at the moment for your evo with decks or cm7.
Side Question: what is the difference between the governors: (Interactive, InteractiveX, Smartass, SmartassV2, Savaged-zen, and Lag Free)?
- Thank You

I like Tiamat 4.1.0, but I can't help you for your side question. I'm still new to development and rooting

i know you said your new but im just wondering have you tried any other kernels?
and what is your battery life with Tiamat 4.1.0

I've used damn near every kernel available for CM7. And by far the BEST kernel for battery life is Savaged Zen. I'm on a stock battery and it just seems to last forever. Add to that the fact that the battery lasts all day without sacrificing performance at all. Every phone is different and you may or may not see the same results. This is just what has worked for my phone. Honestly, your best bet is to get flash happy with various kernels until you find one that gives you the performance and battery life that you're looking for. By the way, I use SVZ Manager with my kernel so that I can toggle SBC on and off as I please. It's a nice apk that gives you some flexibility.

I've tried Tiamat 4.0.8 and a Savaged Zen kernel (can't remember which version). They both gave me about 12 hours of battery life on an average day(for me). But an average day for me is going to school, so I'm not on my phone as much. I haven't gotten to really test the battery life because I haven't looked at it on the weekend when I'm not at school. But like Concordium said, every phone is different! Try them all!

at the moment i am using the latest svz kernel with the svz manager as well. i have been flashing many kernels and for a while i was happy when i used the godmode kernel my phone lasted me 1 day and 6 hours, however he is no longer updating his kernels =( i'm hoping to find another kernel such as that one that will give me around the same results ^_^

I liked Godmode. But it didn't seem to give me as good battery life as savaged zen has given me. Each phone is different though.

well im testing this one out at the moment and it has given me so far 17 hours and 20 mins, still at 31% battery, im just not sure if it'll do better than godmode did, at the moment im running it on the smartass kernel and i ran godmode on interactive so maybe that is the prob... however another issue is i've heard that svz is no longer updating as well... do u know if this is true? and one random thing that only a few people have told me is that they run on performance and overclock their phone and get the best battery from it, is that possible or a lie?
Edit: it lasted 20 hours and 53 mins, so since it didn't do as good as GodMode did then im gonna try the tiamat 4.1.0 now cause it has first place in the poll atm.

Its true that its not being updated anymore. It sucks but I plan to ride it out as long as the kernel functions properly with CM. Once it starts screwing up then I'll switch.
Those who say they get the best battery life by overclocking and putting their phone on performance are full of crap. Performance governor is basically the polar opposite of Powersave. Performance keeps your cpu constantly running at a high frequency. Logic states that overclocking to 1.13 ghz and perpetually running at that frequency requires more power than running at 245 mhz. The more power required the less time your battery will stay alive. Powersave gives you best battery life but gives you crap performance. Interactive, Smartass, and Ondemand give you a balance of performance and battery life. Performance gives you the best performance but crap battery life.
By the way, do you really need a phone that can stay off the charger for more than 21 hours? :-x

no i do not but! 3 days of the week im at school doing nothing for 8-10 hours so... i think if my phone can run longer than a day w/o charging then it mean i can play games on my phone while waiting and by the end of the day i'll still have battery. and does it make sense for someone to get better battery life on interactive than on smartass?

Well Smartass, as I've heard it described, is sort of like Interactive 2.0. It's basically the interactive governor but better. Unfortunately, I do not know enough of the exact specifics of the governors to tell you which SHOULD be getting better battery. I would just run each of those governors and see which one works better for you.
And I thought your phone already lasted 21 hours with a decent amount of usage. You need to test the governors/kernels in the exact situation you are going to be using the phone. Interactive, Ondemand, and Smartass would all manage the phone pretty much the same if you just leave it alone and let it sit till the battery drains. but they each manage the power allocation supplied to the cpu very differently during actual use. One ramps up the voltage quickly while one scales it up more gradually. So take your charger with you to school, in case you run into trouble, and use the phone as you believe you will be using it in the future. Then you'll have a more accurate idea of which setup works best for you.

just wondering what do you keep your cpu settings at: the governor, cpu min & max?

When I am plugged into my wall charger I keep it at 1113/245. I use Performance for benchmarking and testing since I don't need to worry about battery life and Smartass when doing everything else. For normal every day use I have it at 1036/245/Smartass, Interactive, or Ondemand. I don't really have a preference between the three governors since they all make my battery last more than long enough. So it usually comes down to whichever my clumsy finger happens to accidentally select first. If I happen to not go home and need more life then I'll drop to 729/245/Conservative or Powersave. I use conservative if I still need to be able to use the phone a bit and powersave if I want my phone to just sit there and look pretty till I get back home.

You're not bugging me man. This place exists so people can ask questions and get help.
I keep my min at 245 because I've read, in multiple places, that allowing it to go any lower is not something your cpu really appreciates. Just like there is such thing as too high with your clock speed there is also a too low. And everywhere I have seen 245 is the preferred low end. I am not 100% sure as to why but I would assume that it is because your cpu needs at least a certain amount of power to run the basic processes required to keep your phone functional. Similar to a computer. Lower the cpu too much and it just can't do what it needs to.

I don't remember there being a thread dedicated to this. I just remember it from posts I saw within different OC/UV threads. Do a Google search for it and see if that returns any results. Like I said, I doubt you'll find a full dedicated thread. But you may be able to find the individual posts where it's mentioned.

thank you, you have been really helpful ^_^

With Tiamat 4.1 and juicedefender I get the best battery performance and v6 supercharger I have a smooth screen with no problems or lag at all.

To those O/Ced a Q for you.

Im stone stock right now. Do you see an actual improvement in apps that need the extra O/C HP? I have one game I bought that seems to be a little choppy at times, 9mm HD, and Im not sure if its the games coding, the fact that it maybe having a problem with ICS, or just not enough hardware HP to be fluid.

I OC'ed when I first got the phone but quickly dropped it back to 1200. This phone doesn't need overclocking and if you are noticing lag in games it is most likely due to poor coding by the dev for either ICS or dual core phones or both. If it is lagging on a 1.2 GHz dual core and it is our hardware think about people running it on the Inc 2 with a 1 GHz single core processor and basically last years tech. Our phones should be fine to run most if not all games for about a half year or maybe a year before OCing will really be needed.

Why don't you just do it and find out? It's really hard to tell because no kernel is a stock kernel with 1.35 GHz / 1.4 GHz.
All these kernels featuring OC have additional features which means that it could be the features/tweaks that are fixing it rather than the OC itself.

Well,...Im just pretty content with how it performs in every other aspect, except for this one game bugs me a little. Ive been ROMed and O/Ced on this not too long ago, and TBH, theres always some sort of little thig that turns me off about it. A spontaneous reboot here, a F/C there, and I find myself going stock again. I would do it in a heart beat if it didnt mean having to set every last detail back up again when I unlock the phone.

And yes, being virtually OCD about this phone sucks, lol.

I have a question as well!
For those under-clocking or using UV kernels, do you see a noticeable improvement in battery life? I have a GSM sock GNex and the battery life is atrocious.

Should of unlocked the bootloader day one before playing with the phone your phone still remains stock. Just the bootloader is unlocked, you'll virtually feel no difference. Except the fact that you have to relock for warranty purposes later but you'll wipe everything so that is always good because you don't want to exchange a phone with all of your passwords.
@andythefan: Yes there is a huge battery difference. Visit the Franco Kernel thread in GSM forums for people's images of battery history.

Flash the James Bond kernel so your gpu will be upped to 384mhz. It is in the development section.

Other kernels also have this feature. A lot of them do.

@stevessvt: In the myriad different combo's I've flashed (ARHD, Franco kernel, APex Kernel, bigxie ROM, AOKP rom, stock kernel, OC/No OC, Unvervolting, and 1 other kernel I can't even remember) I've yet to encounter a single random reboot, FC, or battery pull. I've also flashed countless different mods and basebands, etc.
It's all about doing your homework and really reading through threads before flashing and making sure different stuff is compatible and doing nandroids.
I can honestly say running a non-stock rom/kernel makes a noticeable difference in response and performance in daily use. Its really all the Kernel IMO, ROM's just give you features. I've however never noticed anything from OCing.
@andyfan: what build are you on? 4.0.2 has the hands down best battery life, and 4.0.3 with the Franco Kernel is nearly as good as 4.0.2 was (4.0.2 for me meant ~3% drain in 8 hours)

For now any phone usage will give you terrible battery life due to the high power consumption of the screen especially if when it displays white onscreen content. Average CPU usage is very low unless you're running benchmarks consistently. Therefore UV tweaks have low impact on usage battery life.
With that said if your battery is irregularly draining while idle something may be active in the background.
Franco has made many tweaks to his kernel to reduce idle power consumption. He's gotten it down to about less than 1% drain per hour which can give you over 2 days of idle battery life. Just for ****s and giggles I have achieved that with less than 30 minutes of screen time with LTE enabled.
Franco's kernel is the best I've used in terms of overall battery life but none of the OC/UV kernels have significantly increased my usage battery life.

[NOOB QUESTION] Overclocking

I have no experience overclocking a mobile device, so I have no knowledge about what is standard/good/bad/safe/unsafe. Basically I want to overclock my Gnex but I don't want to shorten its lifespan. What's a safe amount to overclock to that won't be bad in the long run for my Gnex? (Running Franco M4)

I've personally never found a reason to overclock this phone at all, and that's usually the best for lifetime preservation.

As far as I know recommended maximum speed of CPU is 1,5ghz, so theoretically it is safe to overclock it to this amount. But I don't know if the build of GN for example do not make the CPU heat more what can cause less life time in such speed.

I'm running francos latest kernel. I just picked the highest OC on the list (1344mhz). I think the non-stable goes higher.

Non stable goes to 1500mhz.
About the "to overclock or not to overclock" discussion, i'm leaning towards not needed YET. The phone still packs a punch when it comes to gaming and such IMO.
OP says he is noob with these things aswell, so it might be wise to wait a little and get some android experience before jumping on the OC train.
That beeing said. Every cpu is different so one cpu can be clocked to 1500mhz while a different one will fail when beeing clocked to 1300. You just have to try different clock speeds and check if it is stable or not. The cpu have built in throtteling when temperature limits are reached.

[Q]laggy phone after runing an app for a while

So i am using trinity's stable kernel on 1.2 ondemand gov and deadline i/o sched. My question is: why am I havving terrible performance for example after playing like 10-15 mins subway surfers? It works really nice until i get like 600.000 points,after that I barely can see what's happening,verry low fps especially when i'm touching the screen(might this be i/o related?). So,does anyone have the same issues? Can someone tell me the optimal kernel/freq/gov and i/o sched? And btw i'm on cna 3.8.0 if that's helping with anything.

CNA 3.8.0 is based on android 4.1.2 and there are many stable trinity kernels for 4.1.2. Each with different clock speed for CPU and GPU. So which one are you using? Try another one with higher GPU. There is one with 1420MHz CPU and 512MHz GPU so give it a try if you are not already using it

I'm using the 1420 Mhz CPU and 384 Mhz GPU because of the battery drain in the 512Mhz GPU one. I already have issues with my battery drain cause my phone is thinking that it's charging and my screen is turned on almost non stop so...

What about trying the 512 GPU for a little while just to confirm whether the performance still drops after 600,000 or it will be fine???
Accordingly, I hope we will be able to narrow the cause of this lag
Hope you reach a higher score this time

I'll do this tomorrow at work and i will post the results,now i need some sleep

try a 1344mhz kernel or a 1536mhz trinity kernel. for some reason many devices dont like 1420mhz.

Actually I play the same game nowadays but never reached this 600,000+ score. Generally I noticed that the game is not as smooth as it used to be before the last update with christmas theme. Only yesterday I checked the settings and there is an option to turn this new christmas theme (called Holiday Theme) off. I don't think that the power in GNex is not enough to run this game, but maybe this new theme is having some bugs causing this lag. So try turning it off and see if you still face the same lag you are talking about

Ok so I noticed that not only when I'm playing Subway surfers the phone is lagging but when I'm in the drawer or just switching between the screens...I'm on franco's r300 kernel with 384Mhz GPU. So,what' wrong with my phone?

I don't think there is anything wrong with your phone. It is not very weird to get lags from time to time while using the phone, so please make it easier on yourself
My advice is to try different ROMs and kernels until you are satisfied

I can't help you in ROMs because I didn't try any but using my own AOSP one. As for kernels, I always used Trinity and it is very fine with me.
Just search around for other users' experiences and mostly you will find something attractive to your liking

Ktoon's KT747 2/8/13 Kernel vs Task650's 2/10/13 Kernel

What are your guys' opinions on the performance of these two kernels? From what I've gathered it seems like KToon's kernel is meant for overclocking, but then what would one use task's for?
Task's recent update to his kernel makes me want to try it because I've been using KToon's kernel with the ktoonservative governer and row scheduler UV'ed a little bit but unlocked to 2.1GHz and have been having some pretty bad battery life in mu opinion, do you think switching to task's kernel would be better on the battery?
Well what do you guys think?

Fun Fact for the day. Versus threads get shut down in no time here on XDA.
P.S- Why wouldn't you just try it first before making a thread about it? Kernels take about 3 seconds to flash. Also. No one can tell you that you will get better battery life on one or the other considering all of the variables. We are all in different locations, use different apps, have different settings, and we all use our devices differently. You need to try them both out and see which one works better for YOUR device.

Man why are ya giving me a hard time? You kicked me out of your thread, which I understood and respect, but then you come here and tell me the same thing you told me before and that my thread's gonna go to the bin in no time.
I'm just trying to find out what the DIFFERENCES between the kernels are, because it isn't very clear in reading the descriptions/OP's,
They wouldn't co-exist if they were exactly the same.
I'm not too interested in tweaking the hell out of my device nor do I care too much about overclocking...I just want a lot of screen time and the ability to play games and SMS with little lag.
I have tried out both kernels and didn't really notice much difference because I didn't really know what to look for.
Like, okay or example, it seems to me that your kernel is less for tweaking and isn't for overclocking (max 1.6GHz or something?) while KToons can go to 2.1.

I'm not giving you are hard time. I'm just telling you the facts here. If you're not into tweaking and messing with things then this is simple and really shouldn't make a difference to you which one you use other than battery life, less lag, ect... Which no one can tell you one is better than the other for. Flash one and don't touch the settings for it and use it how you normally would for a day or two. Then do the same for the other kernel. See which one gets you the best results. Its the only way to find out. Not quite sure why you're refusing to take my advice here. Its pretty straight forward.
There's kernel source in both threads that explain in DETAIL all the DIFFERENCES between the two. It literally only takes seconds to flash and see for yourself. This shouldn't be a big deal at all.

I think they re two of the same.Task just doesnt want KT to know he borrowed his kernel...lol jk. But seriously,they're pretty similar.KT seems better on the performance end but I never got the exceptional battery stats that ppl keep posting,IdK it may be something on my end. On the other hand, task's seemed better on my battery as I could not noticeably see my battery drain during use as I did on Kt's. Furthermore my phone does get hot really fast on task kernel,I'm guessing its cuz we use performance control and can't really play in the voltages as much.

Or all or any of that could be due to the apps your have on your device, the settings you choose, ect...
P.S- My phone has never gotten hot. Probably due to what I mentioned above.

I have flashed both kernels. And I don't mean that I am not planning on doing ANY tweaking whatsoever, I just don't mean like messing with voltages adding or subtracting 25 at a time until my CPU crashes so I can find the under/overclock limit...that's the kind of tweaking I have no interest in trying. I'm not gonna look through he sources of both kernels, come on dude you know I'm not a dev and that level of detail is un-necessary.
Your kernel being capped at 1.6GHz probably is better on battery but I also have a sixaxis controller and like to game, does it affect 3D performance at all?

This is the kind of posts I'm looking for in this thread. Do you personally find task's kernel's performance to be any worse than KT's? Cause you said bettery life seemed better.
Also, are the same governers and I/O schedules available between both kernels? The only settings I'm used to using is ktoonservative and row, I wouldn't really know what to do in performance control to emulate what I've done in KTweaker.

He cannot answer this question honestly. He doesn't have your device. You're not understanding. He can have the best battery life possible on my kernel but if you use it, you could have the worst battery life possible. IT'S DEVICE DEPENDENT. Will you please just do yourself a favor and take 3 seconds, flash the kernel, and see. You say you've tried them both, but you are also asking about playing games and what not with them? You would know if you had tried them dude. Same goes for the governors & schedulers. You would also know that if you had actually tried them both. I need to ask you this. Why won't you just try them and see for yourself. Are you really the type of person to flash what people tell you to your expensive device?
Look dude. I'm only trying to help you here. I'm not quite sure why you wouldn't just take my advice here. I have quite a bit of experience with this stuff and I'm trying to help you get the best experience possible. But it seems as though you think that personal opinions of others are whats best for your device when in all reality they are not. Real life testing is what will prove to be best for your device. Trust me.

What You won't have on underwear kernel vs kt747: ktoonservative gov, vibration strength control, screen off max freq control, screen off gov control, fast charge, MHz range from 96 to 2106, undervolting capabilities and adjustments to governors and schedulers.
If you don't want to undervolt or tweak anything, I recommend you use underwear kernel. It is stable fast and oc to 1674mhz is alright for any gaming and it doesn't affect 3d performance.
If you wanna use ktoonservative governor then you will have no choice but to use kt747.
But anyway, what you really need is to try both and familiarize yourself with their features.

Comprehensive list. I like it. Now I gotta figure out which gov I'm gonna use when I flash the underwear kernel.
Thanks everybody for their input, if anyone else has anything to say then please go for it!
Wiping cache + dalvik and flashing underwear kernel then fixing permissions and rebooting and gonna take a look around performance control to see whats up.

Ohh Thnx man. While you're here any suggestions as to how I go about fixing/finding out which apps are responsible? Also,any combinations/settings you might recommend trying with your kernel,despite the phone dependent variables and what not. Thnx )

Running the underwear kernel today, changes frequencies min and max to the farthest it can go. Will report back with my results.

Sorry man, but no need to report back here as it has already been stated that each User's experience will differ upon usage, apps, personal habits, planet alignment,... Boils down to a flash and see type thing.

Here is some info on Governor and I/O schedulers. Obviously it isn't going to include Ktoonservative or ROW but you get the idea.
