Best kernel for MIUI ROM?

I am currently using the miui ROM and am wondering which kernel would be best to use. I'm hoping to improve my battery life, too, so I'd appreciate some suggestions.

Ziggy aosp used to work really well for me on the 1022 version but for some reason I'm unable to flash it on the 1029 rom

That's actually the first one I tried. Froze up on the splash screen for me. Sucks, I was really excited to try that one.

The stock kernel works quite well for me so I'd vouch for that. With that said I've heard good things about koush test2 kernel although with that one not all the governors are enabled (good to keep in mind if you're going to be using setcpu)

Good to know! I am actually using koush test2 kernel at the moment. So would you say that stock kernel is better for battery life? Right now I'm at 8 hours unplugged with moderate use and I have 30% left. Not too happy with that since I have the seidio 1750 extended battery. Does the stock kernel have all the governors disabled? Will setcpu work with that?

SetCPU does work with the stock kernel. Besides, almost all governors showed up in SetCPU's Scaling list box. As an alternative, you may try using Wildmonk's kernels which can be downloaded from http://wildmonks.iblogger.org/. Also use Spare Parts (can be downloaded from the market) in order to check what is draining your battery the most. Sometimes, processes like the MediaServer consume a lot of CPU causing extensive battery drain. Can be remedied by powering down your phone and then starting back up a couple of times. Enjoy!!!!

No oc or uving, this is complete stock KL1 kernel they way it came with the phone. I actually had great battery life (about 17 hours) on stock, but I switched to other custom kernels and didnt have so great battery life. So, I was looking for a stock kernel and in the end made this one and flashed today. So battery life should be like stock.

Quick Q, I can ODIN this over Juggernaut 4.1? Without a wipe/reset?

Thanks. I am getting ****ty battery life also. I have tried everything, faux's, bullet, synergy's different versions, Gideon's UV scripts, underclocking, undervolting, with complete wipe, different roms, you name it. I still I lose 20+% battery per hour while I read on my phone. 10-11% if its idle. Completely ridiculous. Just tonight I thought of trying the stock kernel. Plus anytime my phone is awake, the top portion of my phone gets hot. I'm hoping its a kernel issue.

That sounds really bad. I was getting horrible battery life on other kernels but not that bad (i got around an average of 7-8 hours on custom kernels). However, one thing about stock kernel is that once you flash it, you have to give it 2-3 days -sometimes more- to get full capacity battery life (around 17 hours heavy use for me).

I'll test it out. My only concern was that the phone would warm up for no reason. The only time my phone can save battery is in flight mode. 7 hours in flight mode take about 5-8% battery. So the issue is most likely radio/kernel related IMO. Even having sync/data off didn't help much. I also average 7-8 hours. It's just that when I have the phone on to a dark screen with white text on it (opera mini, it has no fancy stuff, good reader browser) I would lose at least 15% in about 45 minutes. This is with no music, no data activity at the lowest brightness setting.

So this is my battery life after the first day. I would say today was lots of heavy use for me. Usually around this time im charging from dead, but with this kernel I still have 30 percent left to go. So about 15-16 hours on one charge with heavy use .I've tried all the custom kernels and this is the best I've ever gotten....

This one helped lots. I unplugged my phone at 1AM (100% charged) and then put it in flight mode. At 7AM I turned off flight mode and had used up 1% in 6 hours. From then till 3:30 I went down to 50%.

shehrammajid,
Thanks for the stock kernel. I am also trying to learn how to build a stock kernel. I have made a post here: http://forum.xda-developers.com/showthread.php?p=22845175
Can you please take a look at my steps and see where I am going wrong? Also can you post the guide you followed by bubby323?
Thanks.

[Q] Best HOX kernel for battery life (smooth ui no gaming)

What is the best kernel for getting the best battery life? I have tried many and the most screen time I am able to achieve is 3-4 hours. This is better than most users but I am sure that getting 5 hours could be done with a kernel that has proper power savings. The phone is overpowered and ramps up its cpu for simple tasks like sending whatsapps. Also is there a kernel/rom combo for achieving the best battery life that work great together? So far the best for me was the Renovate 3.0 rom running a stock kernel reaching 4 hours of screen time. I am currently running maXimus 2.2 with faux 006m and getting around 3 and a half hours of screen time.
Thanks,

Yes and even purchased his app to see if turning off cores and under clocking would help. His kernel has some serious wifi issues so I could not keep it. But also the cores would turn on even when they are set not to. Seems that it is not perfected yet.

i diint want to open a new thread neither i want to hijack this thread. my questions is somewhat similar to the opening post with only few changes. i like to play games in this awesome screen. i use wifi for an hour or so. i need 12 hrs of battery life with around 30mins of light gaming (temple run/stick cricket/fruit ninja etc) what romand kernel should i use which would give me optimum battery life? currently i am on ARHD8.1 with stock kernel.

Try n3ocort3x's kernels. He's developing his kernels for the most battery life without compromising the ui smoothness and performance. Does pretty well on sticking your custom underclocked values and does a great job on undervolting.

Well if you look around, this device only has one kernel, that all 4.x.x Roms use. Hashcodes. He has done a lo of work in making it. You should think him and not complain about the battery life. And for a tablet I get a good 8 hours of continuous use with wifi always on. That's pretty good, if you want to save battery, try a battery saving app from the play store. Those seem to help people, and turn off wifi when your not using it

The recent changes Hash made to the 3.0.x kernel is now comparable in battery consumption to IR's tweaked CM7 kernal. With the right settings, I can achieve only 10% battery drain per hour of continual use.....which is great for an aging tablet

[Q] help with battery saving kernel settings

Hello. Not sure if this is the correct section or not. But here goes.
I was running rootbox 4.2.2 and kt747 kernel. Along with baconatorx something script to apply settings to second core. I was getting roughly 3 to 4 hours screen on time. Great!
Recently I installed slimbean 4.3.1 after hearing so many people say it has the best battery life. With the according 4.3 kt747 kernel. I applied the same tweaks etc but at best I can get 2 hours of screen on time. Maybe there is a new script I'm unaware of.
I use my phone frequently but not heavily. Just phone calls SMS and abit of chrome. Can anyone give me some advice. Or someone with some working settings with the combo I have? Or should I just go back to what I had?
Any help would be great.

Thanks. Just tried out your settings on my setup with the badass gov and slightly more under clock. And that's all you done?
I'm on 34% and only 1 hour 25 min screen on time.
And its 3rd on the list in battery stats.
I might be wrong but should cell stand by and phone idle be on top for battery usage? This is driving me nuts I have to carry my damn charger during the day.
I will report back after a few cycles.

What I am putting down below are purely from my view and my observations over the past few years.
There could be multiple issues:
1. Your battery might be getting old. On 2.8 I set the record at a whopping 7 hours display time (battery less than 6 months old). On the same ROM I was getting barely 2-3 hours (battery near to or over 18 months old) a few days before I flashed 4.1. So when I got 3h45m today, I consider that a pretty good battery.
2. You signal levels at home, the areas you roam, and at your work/school. These too kill more. Example, battery discharges slowly (when idle) at home compared to when I am at work cos of low signal levels at my work place.
3. Maybe there are too many background apps.
Example: Kik, Facebook, Google Plus. These are known battery hogs. You either uninstall these or freeze them when not needed. Your battery will thank you.
4. Kernels don't suit every phone. What works for me might not work for you. Example: Kernel of 2.8 people loved. But for me it drained battery crazy. I used Kernel C of prior version of ROM. Try out multiple, but give atleast 3 days to validate each.
5. Most importantly, do no UC too much. A phone spending 10 seconds at 1000 MHz could need 30 seconds at 800 MHz to get the same task done, and this could actually drain your battery more. For me, after using multiple phones on multiple ROMs, I found speeds between 800-1200 quite satisfactory. This is the reason my clock is normally set to 1000 as max.
6. I barely UV. UVing a little aggressively might seem to extend battery a little, but in the process it kills the phone processors and other parts. This is because they are getting strained working with lower currents than recommended. Also it is a normal practice to actually send a little more than needed currents to phone processor to avoid phone being shut off.
Our devs here who make kernels already reduce the voltage to sustainable levels to improvise on the kernel. This is also one reason why I don't bother about UVing any more.
Sorry about being lengthy and boring :victory:

Lengthy but not boring at all. ill try to add some more info on my phone and its setup.
1. my phone is less then 6 months old. 2.8 what? kernel version? 7 hours id poop a brick. lol
2. my signal strengths haven't changed at home or at work. I work outside lol however at home i do have a mountain behind me. literally a cliff side and i always got half signal since i got the phone.
3. i got the background stuff kicked. got greenify running and i have it hibernating just about everything it will let me.
4. ok this brings me back to what i was thinking originally. maybe i should just go back to what i had with rootbox 4.2.2 + kt747 kernel and scripts.... was trying to avoid this lol. 4.3 must just not jive with my phone.
5. i do have my voltages under volted 50 across the board. i have had the odd random reboot. my clocks were always either 1.2 or 1.0 ghz. never did oc or uc too much.
i will set my voltages back to stock after a few cycles.
also i run fs trim. supposed to stop lag or something. i been running it on all my devices so i figured i may as well follow suit with my s3. i also renamed mpdesion.
my standby time is still good. ill get 2 days on weekends when im not using phone much. but screen time is still less then 2 hours.
i just finished the first full charge with what u recommended. so lets see. heading out for 10 hours here soon. lets see how it does!

My bad! All my references to ROM or kernel versions pertains to Intergalatic ROM and its kernels. Sorry, I should've mentioned that.
