Kernels to use with All Star Rom - T-Mobile Samsung Galaxy S II SGH-T989

Just made the switch from Jedi Knight 5 to All Star Rom 4 for the massive increase in features and customizations (minus the Jedi themes which I liked and the wifi calling that I rarely used). I love it so far...
The only issue I have is battery life - e.g. last night my battery ran down 13% (usually only ran down 3% with JK5) while sleeping with it underclocked to a maximum of 1Ghz.
I've read good things about the KKO kernel - has anyone tried this with any success with All Star Rom?
Any other hints/suggestions so that I can get a full day out of this thing with moderate use and not have it run like it was made in 2007? (Powersaving mode in ROM control under AOKP isn't cutting it- quite laggy).
Thanks in advance!

Because I am one of the devs behind the ROM, I can say that the h0tcakez kernel goes great with the ROM. To get batter battery life, enable CPU Sleeper and your phone shouldn't lose as much battery life overnight. Also, I am using ondemand governor with noop I/O.

I was hoping maybe someone as experienced as a dev would have some input, and I got a dev himself! Thanks a ton for helping this noob out.

Sense Rom with good battery life

So guys, i definitely need a sense rom because of the look ( especially the music player, 3.0 lockscreen like in insertcoin and apps) and the fast writing speed of my sd card...
i tried leedroid, rc hd mix, maybe a froyo rom would be better? Or recoment a different kernel?
currently i use insertcoin ( newest stable release), but the battery is so bad i can hardly get a day out with normal use... wifi gps off brioghtness low...
can u tell me a good rom? would appreciate it
I find al GB ROMS have poor battery life then I changed the kernel to MANU's and it was much much better. Maybe try a different kernel?
can u recommend me a kernel?
Yeah this one is really good for me but is different experience for every user...

Gingerbread-HAVS-AXI-CFS
Thx dude, i'll try this.
But i gotta 2 questions:
Can i return to my standart kernel (insertcoin eg) and how can i do this?
Is this kernel also compatible with insertcoin? (sense- based)
With Gingerbread I think the Reflex S is pretty OK for the battery or else it is possible to undervolt further.
Maybe you just need to calibrate your battery, if you change your ROM a lot. I use BatteryCalibration from Market and it seem to do the job.
Do i have to do a full wipe?
Battery calibration does not work for me D the percentage drop fast to 99% percent again and so on
Yeah, I would do a full wipe. Especially if you are moving between different ROM's.
So far, the AuraxTsense 8.4 (Android 2.2) was my favorite in terms of battery usage - but since moving to 2.3.3 based ROM's, my battery drops faster when using the phone, but lasts longer when in standby.
what would u recomment then? returning to froyo or stay with gingerbread?
Well, if Battery Life is your primary concern, you would probably get the best results with a Froyo ROM, since the kernels are further in development.
However, in terms of features etc. I think the Gingerbread is better. I personally like the Sense 3.0 improvements etc. So I am just crossing my fingers that battery life will gradually improve further
My experience is, that Gingerbread ROMs in general are battery hungry. As for sense ROMs i can say that LeeDroid suits me best regarding battery life. At the moment im on oxygen and get a day out of it with normal use.
Best results with battery life i had with LeeDroid Froyo ROM (v2.4 i think). Smartass governor and screen off - 245mhz max/min sometimes got me 2 days without charging.
Maybe this helps you finding a solution.
By the way, you can also improve your battery life by turning off the various Auto Sync features, for example Sense Sync, Facebook, Weather etc...
So i've flashed reflex s now, hoping the battery will do better tahn insertcoin.
If not, i will probably change to leedroid froyo- are there any important disadvantages for froyo roms? like speed or something?
i've tried many sense roms and never got a good battery life
now using MIUI rom .. its GUI is close to sense and good battery life
24h and i still have 40% off battery on InsertCoin 1.0.8 CM7,wifi is always on,data is enable,set brightness to auto. Try charge your desire to 100% turn it off,connect charger again and wait till green led is up,than turn on your phone to fastboot menu (power and volume down) and clean battery stats,reeboot.Also You can use battery calibration app from market

thx c: which rom do ya use?
At first, the recommended manu kernel won't be working with sense roms, because it's an aosp kernel (so made for aosp roms).
Second, using setcpu and setting a screen off profile for it really improves standby battery power. I set it mine to:
128 - 442 mhz ondemand governor
Third, the display is the biggest and fastest battery drainer, no matter which rom you are using.

If you use smartass governor, you do not have to set an extra profile for screen off. This governor automatically uses the min cpu frequency when the screen is off.
smartass governor – is based on the concept of the interactive governor.
I have always agreed that in theory the way interactive works – by taking over the idle loop – is very attractive. I have never managed to tweak it so it would behave decently in real life. Smartass is a complete rewrite of the code plus more. I think its a success. Performance is on par with the “old” minmax and I think smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies.
Smartass will also cap the max frequency when sleeping to 352Mhz (or if your min frequency is higher than 352 – why?! – it will cap it to your min frequency). Lets take for example the 528/176 kernel, it will sleep at 352/176. No need for sleep profiles any more!

[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!

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 think that there is much difference between Custom rom and Adroid versions, I noticed that JB seems to be more of a power drain hog than ICS.. But as usual it mainly depends on your personal usage and the main drain source is (then) always the screen.
Lowering the screen brightness will have more effects than kernels and custom roms

Need help with a Gingerbread rom

Hey guys, when i started using the epic touch which was pretty recent, I jumped straight in to the 4.x toms. Currently on blu kuban. Now I really want to go to the best possible gingerbread rom for battery life. I have no idea which rom would have the best battery but I am extremely frustrated with my battery drain on ICS. Can anyone please give me their opinions from what they remember from the gingerbread days or if there is any other way i can drastically improve battery life on ics either with a different rom or kernel? Thanks.
On GB the popular roms I remember were Caulk's and Blazer but I had a stock rooted EL29 setup that I stripped down myself and used QQ Launcher on and really enjoyed for a while. Honestly though battery life is really about the same for me on ICS and GB. I'm currently running agats rom but wicked sensations, aokp, and black rom are all pretty similar in battery life. I'm also now undervolted by -.50 and that has helped even more.
Honestly though its really just a matter of managing your phone and knowing what is running and burning up battery in the background. Use dark themed apps, turn off wifi and 4g when not in use etc.. I also use data enabler widget and turn off data at night now then just toggle back on when i wake up. Last night I dropped 2% in 6 hours.

Undervolting is supplying less mV to your CPUs. In terms you can extend you battery life as the phone can operate at the same speed using less voltage. (Less power used, more battery available)
With that said, don't under volt too much usually -25mV to -50mV is optimal if you go any less you run into the issue of nit having enough voltage and your phone could freeze or crash. Both agat's and kuban kernels offer undervolting and under clocking.
Just a FYI I'm using sleshepic's the governors kernel. No undervolting, just have it set to CFQ and Pegasusq at 1000 Max and 200 min and I've been getting around 11 - 12 hrs with moderate use.

Yes voltage control on kuban kernel allows you to under volt. If you click on each step(slide the voltage to the left) you can under volt it. Then apply settings and your good to go. PM me or reply here is you have any more questions.

Voltage and governor control is now built into Kuban ROM. It's all in extweaks in the system menu. You may want to try it out. You will be losing a lot going back to gingerbread. I actually get better battery life on Kuban than I ever did on GB. And I haven't even messed with under volting. I do recommend the Wheatley and Skywalker governors for the perfect balance of performance and efficiency.
Kuban has been good for me as well.. I don't under volt at all.. To unstable on my phone.. I get 4 hours screen on(heavy use) and good deep sleep with the Kuban kernel(1100-200), placebo tweaks, odexed a few apps, and a modified framework to make it more zippy without compromising battery

Discussion of battery life after linux 3.4 upgrade

It seems that in general battery life has taken a hit for those on a 4.2.2 ROM with the new 3.4 kernel, though the extent of the difference varies. For me personally, I used to get <1.5% per hour drain at idle. After the 3.4 upgrade, with NO other changes, I get around 4% per hour. When I view the BBS stats the number of wakelocks/alarms don't really seem all that different, so it looks like the 3.4 kernel just uses more juice to do the same amount of work. Undervolting doesn't seem to help much, if at all.
I've brought this up in other threads but it wasn't very productive, so I figured it might be worth it's own thread. Does anyone have any idea what exactly might be causing the increased drain? Has anyone figured out and tips/tricks for getting back to 3.0 level battery usage?
What rom/release and 3.4 kernel/release are you using? Which ones have you tried?
Same thing
I am seeing the same thing as you. I use to get really good battery life during standby and now it isn't very good. However, some time (for a couple of hours) it will be back to what it used to be (i can see the slope in battery usage flattens out), but then it just goes back to being crap.
I hope somebody can offer some help...

What rom/release and 3.4 kernel/release are you using? Which ones have you tried?

I've tried pretty much every release of task's AOKP both with and without Ktoonsez's kernel. Battery drain has been about the same with both kernels.
I am on task and ktoonsez latest. I average 24-30 hours of battery life with 4 or more hours of screen time.
Change your governor and scheduler. Those can make a huge difference. I prefer on demand, you should experiment with each scheduler. Maybe try one scheduler each day

I use ktoonservative. It's hard to believe that any of the others would significantly increase my battery life, but I suppose it's worth a shot...
Have you tried JuiceDefender
JD really works for me.
