I've been keeping up on the changelogs for entropy's daily driver and I have noticed his evident concern for the bug starting in 2.6.35.12, and I was just wondering what the differences are between say 2.6.35.7 and 2.6.35.14? and whether or not that bug is really that big that I should worry about it or not?
on a separate note, right now I'm kinda struggling to figure out whether to use Siyah or entropy's daily driver? its definitely noticeable the difference when testing benchmarks I think Siyah is faster, but other than that theyre pretty similar for practicality's sake, however I do like the 100mHz CPU state in Siyah just for saving battery there...
Does anyone have one they prefer or real reasons for one or another?
Thanks
I think you just have to use the one you like the best. Entropy described it the best I think in another thread. He is a little more on the conservative side but focuses on stability. The siyah kernel is very good. I tried it for a day and had no problems. I just use entropys cause I know his work. Just go with the one your happy with.

I'll give you my theory on what I chose.
I've been using Entropy's since this board debuted. I've liked his work from back on the Infuse boards prior. He's very active around here and very knowledgeable. That right there goes a long way for me.
As to the actual kernels themselves, I tried Siyah for a few days and honestly had no issues other than the occasional issue where when locking my screen, it would take a screenshot instead. This might be fixed by now. But, as you said, it benched very well. With that said, the overall experience to me was the exact same with basic UI navigation along with watching videos and playing various games.
I have nothing against the Siyah kernel but from what I mentioned above, I'd rather use and help support Entropy with his kernel and report any issues that come about. Luckily, I've yet to report on a problem...
Like the others have said, it's really a matter of personal preference. Flash both and try them out.
I personally prefer Entropy's for the battery life and stability. But Siyah is also a very good kernel that places emphasis on performance. It can't hurt to try both.
It's not necessarily a bug that occurred in .12 - it's more like a bugfix that broke stuff dependent on the bug. It's a display-only thing - e.g. there are no known benefits OR drawbacks to .14 (that's why it's experimental - it's an unknown) other than that some forms of battery drain will no longer cause Android OS to be extremely high in the rankings in Settings->About Phone->Battery Usage.
e.g. it's harder to notice some causes of drain
As to Siyah vs mine - Siyah is for those that want to live on the bleeding edge - experimental CPU frequency governors, more aggressive application of patches - it leads to potentially better performance but can also lead to a higher likelihood of encountering a regression (something that broke).

Hey all,
I come from an extensive background in OC'ing my own systems, pushing them to the extreme for noticeable performance increases. The one thing I know though, is that it does add wear and tear on the components, and shortens their lifespan. Is overclocking the Vibrant really worth it? I'm not sure if, with a ROM like Axura 2.2.5.7 which is blazing fast already, an extra 100 or 200 mHz is really worth the risk/performance.
What do you all say?

the only reason i OC is basically just so i can tell myself that i am OCing. If that makes ANY sense. its basically just my phone OCD.
to answer your question, even though you kind of already answered it yourself: the only reason you would actually NEED to OC is if you game a lot on your phone, if you do a lot of multitasking, or if you have a lot of data transfering going on (which i do). other than that, our processor is pretty powerful, and can handle 95% of what is thrown at it.
With that said, since youve indicated that you are satisifed with your phones performance, i would say the only thing you should definately do is install a lagfix (if you havnt already). if you dont need to OC, do your battery/hardware a favor, and dont.....unless you have phone OCD like myself.
PS - not to ramble on, but there was actually a 2-day period where i actually wasnt OCed and i didnt know it (i guess my app reset itself or something). i remember saying to myself during that time that my phone phone seemed a little laggy and much slower than usual....then once i discovered that my OC wasnt applied, it made sense. but keep in mind, i have my phone doing a lotttttt of things constantly, so OCing may not have the effect on lighter users that it does on myself. pretty crazy what a .2 ghz difference makes
Like above stated, OC is only needed if you do some intensive task on your phone. In addition, most of the Overclocking Kernels are targeted at a broad audience, what I meant by that is the developer bumps up the voltage enough so that only a small amount of people experience crashes. However, user generally have no control over the voltage themselves and any increase in voltage is bad for electronic components. (exception being some of Eugene's kernels which allows UV by user).
I don't, its not needed. I like my battery life.

I dont usually oc unless I am near a power source. last night i tried the Dow kernals and wow my phone was dead within ours even while in standby. Imo thats just nuts. Even while Oc'd it shouldnt die that way.
What I am looking for is a kernal thats compatible with nero v3 that will maintain battery life aslong as I dont oc.
I have seen this post http://eb-productions.proboards.com/index.cgi?board=samsungsgs&action=display&thread=28&page=1 on Eugenes forum but non of the info makes sense. The one that does make sense has a older modem than the one I am using.
I guess I am use to the hd2 in which I would underclock to maintain decent battery life and use profiles. It doesnt seem like this cpu likes the profiles. amirite?
I would OC no question if we could get a UV kernel with good battery life like we did with Eclair. I won't do it with Froyo because of the terrible battery on i9000 kernels.

What TopShelf10 said is correct. Basically the trade off is this.... faster kernel.......quicker battery drain. That is the trade off. I have used oc kernels ...I do not use the phone for games, so EVERY thing I do on the phone the oc is not necessary. That statement is true for 95% of us.
BUT, that said, there is some cool macho feeling you get when your phone is in overdrive, just like my car, 350 hp but I live on an island that only allows 25mph speed limit...still, it doesn't change that feeling of awesomeness I get when I start the engine
I had nothing but issues with each and every OC ROM I tried. App alarm, pandora, slacker, ect. It was always something. My phone would actually get random freezes so it made the phone feel slower. Voodoo or OCLF on the other hand work wonders.
is it worth it?
well, here were the trades i had with dow14:
going from 13-14mflops to 18-19mflops in linpack (yeah, it's a benchmark, but it's hard to otherwise convey how the oc directly translated to the phone being extremely fast otherwise).
battery life went from easily going 22+ hours between charges to going 6-8 hours between charges.
however, with the core 1.2 oc i had great battery life and performance. so i assume (and have gathered from reading people more knowledgeable than me) the battery downside is due to it being a i9000 kernel. so hopefully/eventually we will get source for the vibrant 2.2 kernel and get an oc kernel with similar performance but much better battery life.
and until i flashed nero v3 and using voodoo, i kept super io and dow14 kernels on my phone so i could flash the oc if i wanted the performance or flash super io for battery life/day to day.
Hello everybody, I'm opening the thread just to read opinions from you all about the kernels that are currently available.
The one I've been using is void #echo, which in my humble opinion with the combination of a tweaked deadline scheduler and a lionheart governor provides great performance, battery life and minimum lag whatsoever.
I do understand that it depends on needs which shall be used, however, I would like to know which one to you guys works smoother and provides better performance / battery life.
I always aim for performance over battery life (I didn't buy a SGSII to get poor performance )
In terms of battery life, I can get it up to 22~23 hours on battery, using WCDMA only / HSPA+ during day and enabling airplane mode during night.
Fast Dormancy disabled and deep sleep working correctly (XXKL1).
I don't like the complexity of siyah and to be good on batt you have to tweak it more with UV and thing like that ,wish is not my style to make trying/errors on my brand new 600$phone !
I tried speed mod wish is very great actually with great overall perform
void echo is the one Im trying right now ! since 2 days its feel very strong and good on battery with good performance on games without getting the phone very hot
neak is good but its more a copy/past of the overall coders over wish is good in one sense but its a bit laggy in game with lucrative mod but defenatly one of my favorite kernel out there ! Im waiting for 1.3 to let simone correct some bugs
Siyah is the tweakers' heaven. You can fine tune every last bit of your phone.
I personally love void, it feels very fast and has good battery life.
I tried NEAK for a short time and it seemed fine but quite many report lag in games(using on demand governor seems to fix it though).
Thanks for the feedback guys, I'm waiting for N.E.A.K 1.3x too

as one of the posts above said siyah is the tweakers heaven..haha trust me i never used it before as i thought it was to complicated. but once you have done your reading and read other peoples posts and what they do to get the best out of the kernel you have a winner...all the rest look good i am not saying anything bad but for me from now on any rom i use siyah is coming with me due to the fact it has so many options to it and so much i can play around with i am in heaven
hope that helps...oh and on a side note i have been tempted to upgrade to a different rom but the current base i am using and with the kernel i have and the settings that i am using the only time i will actually jump ship is if one there is a stable cm9 out there by the amazing team hacksung. Two if Gokhanmoral does a siyah kernel for cm9 which i think will be when kernel sources are made available and three cause i have already my voodoo app all configured with my poweramp player to get the best sound possible i would be foolish to make the step at this moment of time...
So my advice for battery speedmod if you are not into tweaking alot with voltages and clock frequencies and if you want the best of both worlds then siyah

Great feedback bro, I tried Siyah in the past but honestly when I used it I didn't know there were parameters to tweak (didn't check the REF documentation LOL).
Do you get smoother behavior / better performance / higher benchmark scores tweaking the parameters? In quadrant I get around 4604 with void.echo.
as my "personal" opinion...
since i instaled V3RTR3MA.V.4.0 rom, i've been using void#echo
couldn't ask for more its fast and stable... nothing too complicated and i could get 8186 in the quadrant benchmark... a really great kernel...
void echo.By far best kernel for common user,who doesn't want to do all kind of tweaks&stuff.By default is great.If you are into a litle tweaking, you can OC and UV without any issues.
I used it since it was released.No issues at all, battery friendly, great performance.
Trully a KISS principle follower.
My personal advice to all,avoid all roms&kernels that are heavily customized and have alot of useless "tweakes" and scripts on them.The more things on it, more chances of breaking up.
Look for simple builds,as close as it can be to stock,eye candy is not performance.
Jkay makes great themes wich you can apply to the rom.

100% agree most of the battery better and greater speed for these kernels is actually unproven and just advertising bumf .
I have used the kernels listed in the topic and in each case stock kernel has benchmarked better using multiple tests .

I agree with your opinion, and that's the reason why I use only Sammy Stock ROMs
I've flashed a number of roms and kernels in the past few months since May, best combination for me is usually a near stock rom, plus a stable kernel like Speedmod, they just work without needing any tweaking apart from custom set up that's it.
I don't generally like the number of tweaks in some roms but each to their own.
I find stock fine and fluid and stable enough without much problems.
Yeah..i get 6500+ without rawr and oc to 1600.you forget one thing,ALL other kernels have tweaked I/O scheduler enabled. Knzo says very clear in his thread.it's a way to cheat,that's why this tweak is not default on his kernel.
About rom,look for odexed.tornado2 by brotuck is one of the best around(odexed,pretty much stock,only useless apps removed from it).combined with jkay theme and coid echo...my s2 flies

Thanks for the suggestion dude! I'll take a look to it! Beside the removal of stock apps, what tweaks are included to achieve that score?
Best kernel so far for me is hardcore's speedmod.
Fast, first time I broke the 6000 barrier on Antutu benchmark without overclock. And great battery life, one full day + charging only by the end of day two, with normal use.
Normal use for me is making phone calls, surfing web and playing games sometimes, not more than 20min per "session". Turning wifi and 3g off when phone on standby. And switching to airplane mode overnight.
And yes I tried other kernels....

None.i dont flash a rom for benchmark scores.i flash it for how it works.those benchmarks cand be tricked,but whats the point?what do you preffer?a rom&kernel with high results on tests,but moves like crap,laggy,fc's with high battery drain or a phone that is snappy,smooth,fast,great battery life and works properly?

I have been using void echo kernel these past few days. But I switched to Speedmode because of an issue. My phone gets very hot once I backup my nand on CWM. Also sometimes when I play games. Do you guys have this issue too?

I have run PBJ, Saber, Perseus and Beans Stock so far (all on Beans ROM). I only messed with overclocking and undervolting on perseus and frankly didn't notice any real difference. For me Beans Stock has been the best for battery life (just cracked 2 days on a charge with 3 hours of screen time), but even that is only slightly better then I got with the other kernels. As for performance the phone is so good I can't honestly say one is better than any of the others. I am sure some people can post some test scores that show one being better than the other, but I am not sure in the real world there are major differences.
Alright thanks
I like my kernel Really, stock is already pretty good. For what 95% of users need, it will do just fine. My kernel just strips out a lot of stuff from stock and leaves you with pretty much just what is needed for the kernel to run, not much more. Overclocking isn't going to do much for you outside of getting pretty benchmark numbers. Undervolting also isn't going to do much for battery life as you won't be able to drop the voltages enough to do anything appreciable. Having 50 different I/O schedulers and CPU Governors is great on paper, but really, most of them aren't going to improve performance or help battery life.

For what it's worth, PBJ was a close second on my device to Beans Stock. I would rank them 1 and 1a. I totally agree on the OC and UV comments...I tinkered with them a lot and it didn't seem to do anything. Appreciate your work...I was a Tweaked devotee on the droid charge.
Something that people probably don't realize, overclocking and undervolting will negatively affect the power usage stats in Settings. They are based on specific power usage levels for each frequency, and if you add frequencies or change voltages from stock, the stats won't work correctly. Will it be a big difference? No, but it will be affected nonetheless. It wouldn't make the battery drain faster or slower, but it would affect what application(s) the system sees as using the most battery.
Alright so if I use your kernel it won't miss up MeanBean stuff?? Are should I just leave it stock

Subjective questions and what they do for you:
As a member of many different forums and networks, I see people asking subjective questions all the time and wanted to expand on them and what they do for the person asking.
I am going to use the topic of smartphones for the purpose of this post as it's easily the most frequent.
People always ask what launcher they should use, or what app works best for something etc..
Typically my answer [albeit cold and withdrawn] would be something like, "try all of them and choose the one that works best for you". This response is usually met with hurt feelings or some troll itching to lash out and pull his keyboard commando card.
I will liken this scenario to a car or truck. If someone were to ask me or you what make and model of car you drive and what you like, you could easily answer Kia [I'm using what I drive as an example here]. Then typically they would say they heard Chevy was better or Ford has something similar blah blah blah.
Ok, then if Chevy makes something better then why the hell did you ask me?! This type of question is always subjective because it builds on my personal choice. My preference. But the person asking the question almost always has their own preference or bias which taints the question to begin with.
Any question that asks a person or group of people for an answer that is inherently based off of personal preference begs to be answered the same way. It also makes the person who asked the question look stupid because they were too lazy to simply try the options and make a calculated decision themselves. They don't have the capacity to form an answer of their own. This is the uneducated method.
So when someone asks me which launcher I choose, I could answer Apex Pro. But that's only because it works well for my needs and my application which is specific to me and me only. Hundreds or thousands of people will argue why Nova, Launcher Pro, Chameleon or one of the many other launchers is better. This is an endless argument as again, the best launcher is the one that works best for you. On your phone. With the apps you have installed. The way you use your phone. The same holds true for kernels. Case closed.
Subjective questions will almost always be met with subjective answers. The easy way to not make yourself look and come off as lazy or stupid is to try things yourself and decide which works best for you in your specific situation.
OK, I realize that everyone has a different idea of the best ROM and/or kernel, and I fully expect to try out a few different ones to see which is best for me. However, I am hoping that I won't be irritating anyone by asking for suggestions on where to start. I don't need a lot of extra features, but I do like to be able to configure as many settings as possible--that is the main reason I chose Android in the first place. I also want to maximize battery life. Based on my experience with SlimBean on the Nexus S, it and SlimKat will be definite contenders, but which others should I consider? And are there any specific kernels I should look at? It will be a couple of weeks before my LGOG arrives, so there should be fairly stable 4.4.2 based ROMs by then, but I don't mind using 4.3 ROMs if they will provide better performance. I have been using a Galaxy S II for the last several months, where NeatROM is the only real choice if you want good battery life, so I'm a bit out of the loop.
I have been having a similar issue with trying to maximize performance and battery life at the same time. I have found that using android 4.3 really does make a huge difference in battery life and it makes all the animations, I think, look more fluid. Now as Kernels go, I cannot recomend one in particular, but look for one with eco mode or just change your processor setting with Trickster mod. I use only 2 cores, the ondemand governor, and keep my frequencies between 1026000 and 1512000. Hopefully this helps.
Hello there,
In the last 2-3 weeks, after cleanly reflashing 32.2.A.5.11 with stock repacked kernel, I noticed that my phone is getting unusually hot. This was happening especially while using navigation (Waze) with data on, and consisted in the SoC getting to 50-55°C, apps getting closed (including foreground Waze) and phone being generally unresponsive.
Before this last reflash I used AndroPlus v42, with largely the same suite of installed applications, and with a slight difference in ambient temperature of maximum 5°C due to obvious reasons.
So the question rises: Has anyone seen this kind of difference in thermal behavior between stock and AndroPlus kernels?
Thanks!
PS: I didn't go too much into the details as I don't have them, especially about the previous kernel settings. So I only expect some rather generic answers. I might decide to switch between the two kernels in the next 1-2 weeks depending on available time.
PS2: I only switched to stock because I wanted to have full original functionality of the phone, but might decide to go back to AndroPlus as X-Reality and some camera de-noise functions are of minimal importance to me.
I recommend you use Zach's kernel (https://forum.xda-developers.com/z5...rnel-zachs-kernel-playground-z5c-wip-t3350690) by @zacharias.maladroit. Latest version for Nougat (2_12_2) is stable and runs quite cool. Last night I just disabled Core Control and enabled SOC temp toggle under Thermal using Kernel Adiutor. Currently testing if it makes a difference.
Anyways, give it a try.
