Which Kernel

Which kernel gives the best battery life?
Sent from my SGH-T989 using XDA

Your question isn't an objective one , it's highly subjective but if my irrelevant opinion is going to appease you, try the macnut kernel from Eugene with the lionhdart governor.

Synergy kernel has awesome battery life.
So does the one suggested above....Eugene's Streamline kernel.

Synergy vs. Streamline?
I know both are good but which kernel is better for battery life
Eugene's streamline or Newest Synergy?

Faux123 is the best.

I think it all depends on the ROM and how you use your device....one kernel might give me great battery life and give you decent battery life...try them all and make a decision

Let's not forget tdj 's darkside kernel. Gives awesome performance with great battery life

Why? I don't think it's better than synergy or streamline in battery life.

Yes it does. But which one gives better battery (not performance) synergy or streamline?

Thanks. Does streamline come undervolted or must I undervolt It
myself once I flash it? And that's with the Lionheart governor right?

So I take it streamline with Lionheart gives better battery life than Synergy with interactive or ondemand? Is this true?

[KERNEL] Adama 003

Heyo
I've compiled a *very* simple kernel for our phones just to play with
001
- O/C to 1.8ghz by default
- insecure
002
- should boot up to 1.5 by default (read more on this below the log)
- raised max clock to 1.89GHz
- lowered voltage on a many frequencies
- added init.d support (busybox needs to be installed to /system/xbin!)
Also I'd suggest having your OC app (like SetCPU) go ahead and set your clock at whatever you want your max to be. thermald (a service which watches your phones temp and lowers it if it gets too hot) seems to be messing with the clocks until you set one after it's all booted. So if you don't want to OC, just set it to 1512000 in the app and click "Set on boot" option or whatever it may be.
003
- fixed kernel not being insecure
- sped up L2 cache
- more uv for 648000 and 702000 frequencies
================================================================
More to come as I play with it. Seems pretty stable (and warm!) at 1.8 ghz.
Thanks to faux123 & mdeejay for helping me out with a few things
Flash at your own risk. Make sure you have a NANDROID backup. Flashing the stock kernel via ODIN may not be enough to restore your device. You've been warned
Installation instructions
Reboot into recovery
Wipe cache
Wipe dalvik-cache
Flash kernel zip
Reboot

Awwwww yeaaaaaa!!!!

Awesome thanks roman. Just saw this on twitter.. downloading now edit it works roman , what would you or i need to do to add bootanimation.zip support thanks again

I love you roman!

nice job Roman! my buddy has a Galaxy nexus and he swears by your AOKP ROM. shouldn't be too long for that now that we have our first booting kernel?

Nice work and nice to see you around. Thanks!

Roman, you are AMAZING! I'm so happy to see the first custom kernel on the SGS3 (US)!!
As for quadrants dropping, I'm almost 100% certain it's due to some sort of overheat protection. I know on the Galaxy Nexus, Morfic has a toolkit for his Trinity kernel that allows disabling of the heat protection just so you're able to get a full Antutu (or quadrant) score without the heat sensor kicking in and throttling your phone.

Hi Roman,
Thanks for putting this kernel together, appreciate it. Can i ask your SetCpu settings if you even use it?

Use Nstools its a much better app.

The effort is appreciated can't wait till we get some unicorn power bro! Glad you got this phone.

Any chance of UV the lower frequencies to help save some battery while on standby?

I believe you can run "stop thermald" but I'm not positive.
Sent from my SGH-T999 using Tapatalk 2

to be honest. this thing already is PLEANTY fast. i dont see a need to over clock. if anything we should try for some undervolting and battery life saves. we all love high quadrant scores for bragging rights, but when it all comes down to it. we all just want a better preforming device. quadrant scores arnt everything.

(Discussion) KT747 3.0.45 build 10/9/12

Wondering what settings your running on ktweaker for this kernel and its effect on stability, performance, and battery.
SCREENIES ENCOURAGED!
Is it just me or is the battery on this kernel not that great when on power save option?

No problem threads get buried quick around here, very busy place

SGS3 aokp jb, d2att 3.9.12 by task 650+ktoonsez kt747 kernel
Here are my ktweaker settings, I get plenty of batter on this for what I do in a day but y'all may vary..if you feel you need more I would set it up as follows
Min-96
Max-1350
I/o-sio
Gov-ktoonservative
This was recommended by ktoonsez himself as a good all around performance and battery set up
You also could probably under volt with these settings by about 10
Also make sure that your system performance settings match your ktweaker setting bcuz if not your phone will become hot and unstable! A lot of times will reeboot itself...
Hope this helps if it does please give me a thanks!

I tried some tweaks with bfq and abyssplug. So far I gat better use of the CPU, good battery life, no lag and low latency. Try them and tell me if you get good results.

Do governors need to "settle in" like roms/kernels do?

I've been running agat and recently switched my i/o scheduler to SIO and governor to ktoonservative (from cfq and ondemand) since I heard it's supposed to be great on battery. Since then, however, I'm getting about the same battery life with less screen on time and with battery draining apps like facebook uninstalled. Do I just need to give it more time?

Sure, I usually go through two charging cycles before I rush to judgement.
Give it another good day or two.

Owners settle into their phones and stop fiddling with them constantly, not the other way around mate.

No they do not

Governors Are a setting roms don't actually settle the cache builds as you use apps and the rom there are multiple caches as well

CPU governors and I/O schedulers?

I've started this thread just to know the best governor and I/O scheduler combination. Post the combination which you think is THE BEST!

I use Deadline and Smartmax. Sometimes Smartassv2 or Ondemand as well.

This doesn't belong here.

and on to on topic, i use smartmax with Noop schedular
Noop is said to use less cpu cycles so its KIND Of a battery savin schedular

Smartmax + Deadline...

I use smartmax and bfq while charging @1.7 GHz
And smartmax and noop on battery @1.5 GHz .
