Air kernel best settings? - Nexus S Q&A, Help & Troubleshooting

Hey what are the best battery saving + good on performance settings for air kernel e. G governor and scheduler and btw I'm using slim ics 3.5 so is there any better kernel for battery saving.
P. S I'm running lion heart noop atm with 100/1200 and not too sure if it's killing batteries or not..

My suggestions:
use a lightweight, stockish kernel
---> slim ics is a fast, streamlined ROM and coupling it with a heavily modded kernel may only burden it with unnecessary overhead, so i recommend using stockish kernels like Franco's, _thalamus', or Pete's
play with the right governor-scheduler combo that works for you
---> if you're vent on using Air, you have to try out the different combinations that will work for you. Every phone is different and your phone has its quirks and strengths. When I used Air, I used a noop-lazy combo as this gives me the best battery life and performance when I need it, but this may not be true for you. So experiment and benchmark. This is what makes Android special: the power of choice and customizability.
Cheers!

go for the air kernel weekly 4.0
smartass v2 with noop scheduler and deep idle on .. works smooth and amazing battery life ..

What would you consider amazing battery life?

air 4.0 [Only Voodoo Colors (Original)]
with 400-1200mhz cpu freq ,deep idle on
smartassV2/ noop is not stable for my used.
have no reason, reboot random ...
try to ondemand dadeline
200-1000 cpu freq , deep idle off,
I think this is helpful

Your overclock isn't stable then.
It's a not a "per use" thing. It is just as stable as ondemand with deadline.

I had my best experience with
ondemand (lower the up threshold to ~85% via nstools, than it's smooth as butter)
200-1000 Deep Idle ON (ensure that deep idle works properly with TOP=OFF)
Deadline

[Q] Is this okay for me to do?

First off:
Rom:
Virus rom RC1B3
Kernel:
1.8ghz bolted BFS uv kernel
if you overclock, your battery life is less. more power = more usage
so, in theory, if you underclock, less power = less usage..
when I'm at work, I barely use my phone. Maybe to text or a call here and there..
So I wanted to improve my battery life as much as I could,,, I have SetCPU and I have the minimum at 350mhz and the maximum at 650 using the smartass governor when not in use.. Since this is underclocking, the battery life has improved drastically,, though is it safe? I don't see any reason why not, just though I'd like some input on it.
Yeah, you're fine. With the Smart-Ass governor you don't really need to underclock. It's called smart-ass for a reason. It will only use as much is needed. So when your phones screen is off not running any tasks, the governor will underclock itself.
Another thing to add is if you are using SetCPU, then you really do not need to set up any profiles that would underclock the phone if you are using smartass.

[Q] Confused about which governor to use with Speedy-7

I'm a litte confused about which governor to use.
By default this kernel uses conservative and it performs quite well. I would expect it to be less snappy, but the difference is very small. Especially scrolling through the home-screens etc. is fluid.
Now, interactive is supposed to be the new ICS default-governor and normally you would expect it to be sthe snappiest one. Anyway, with interactive scrolling through my home-screens is a little choppy... How can that be?
SmartassV2 seems to be good in an overall-view, but I'm not sure what to think about it, because I generally would prefer using a more classical governor.
What governor would you use on a stock-4.0.3-ROM with Speedy-7-Kernel if you don't use heavy apps or games, but want all those general apps (launcher, browser etc.) to rum really smooth?
Thanks

Hi,
i use lulzactive on my Nexus S.
If you use it with NS tools, it gives you more option to control screen off freq.
With that it has great battery life.
lulzactiveV2/sio is the smoothest for me. Anyways I don't know yet which is the best governor for the night when I sleep. Can I use powersave? When I don't use my phone it should stay at the lowest clock as possible.
Sent from my Nexus S using XDA App
personal experience: wheatley --> luzlactive --> lazy , best battery-performance balanced
Thanks for all your answers.
I've tried all those governors now and I think smartassV2 seems to be the one I will use for now.
But some other question: The kernel offers Live OC. It seems pretty clear what this is: All the speeds are increased by x%, including the bus-speed of 200Mhz, without increasing the voltages.
Lets say I just overclock about 10%, so the maximum-clock is 1100 Mhz, without increasing the voltage. Will I drain more battery than with 100% speed? And is there any visible advantage in overclocking just about 10% or won't I see or feel any difference at all?

OrDroid 7.1.0 battery life

Hello All.
How is the battery life on the new rom ?
I have the 6.1.0 Rom and its killing my battery , any one has the same issue ?
Was trying to switch Kernel no luck ...
Honestly, best for you to judge for yourself since everyone's configurations differ.
Also, might be a bit early to tell since I don't think the ROM has even been released for a day which means most people may not have even used their phone enough to have an opinion.

Well, it all depends on how you configure the installation. What options did you choose?
For the one day that I have used Ordroid 7.0.1, I've been quite happy with the battery life.
SetCPU 1188 Max 192 min
governor ondemand
scheduler cfq
ordroid 6.1.0
Kernel 3.0.28-RCMIX
Base 11.69.3504.00P_11.22.3504.07_M
Build 1.78.401.2 CL58751
The ROM was released not very long ago. So there can´t be a right answer until now.
The Phone needs some "Complete empty" -> "Full charge" cycles to show the battery properly. A battery wipe is not the right solution.
Beside the CPU, GPU and stuff setting, lots of battery drain is caused by the synchronisation. So check if everything is really necessary.
Live background wallpaper need energy as well. So with some setup, you can bring your sensa to 1,5 days without surrender on anything.
With stock ROM it´s possible to get 2 days, but dont watch the screen to often ;-)
Well, I've figured that you can get maximum battery without much performance compromise if you configure it as:
Sweep2Wake {Yes (no capacitive backlight)} or {No}
ZRAM {No}
3DGPU Overclock {3DGPU OC disabled}
2DGPU Overclock {2DGPU OC disabled}
Governor {badass}
badass config {Balanced}
I/OScheduler {cfq}
Maxfreq {1566 MHz}
Minfreq {192 MHz}
Screen off max freq {486 MHz}
Keep the screen brightness at 35%. Switch off WiFi when not in use. Remove your HTC Sense account unless really required.
The lesser the number of accounts you have, the better it is.
Hope this helps!
Now its rebooting in a call

Thanks il do this when installing the new ROM
Any news guys ? Did any one tested the new rom for bat life ?

I configured the new ROM exactly like this .
Already did one full discharge .

[Q] How do I use no frill CPU?

I want to overclock my phone. I have doom kernel v14 installed. I installed no frill CPU on my phone. The min frequency I seleted was at 300 MHz (approx) and the max was 1.4 GHz (approx). Does this mean that the phone will automatically go between these values if I run a heavy app (eg GTA 3)? And what does the 'governor' and 'i/o schedular' mean and what does it do? My current settings are :
sio - I/o schedular
Performance - govenor
Min - 245
Max - 1.2 Ghz
Governor : Smartass v2
Mine is like this.
and what about the i/o scheduler? And what does govenor and i/o scheduler mean?
I'm also on Doomkernel v14 and my battery is draining so quicky. Its dropping 5% every 10minutes even when I'm using any light application. I have SetCPU and my sttings are Max 1401MHz and Min 134MHz with smartassV2 and deadline. Although speed is amazing but battery performance is terrible.

Performance governor is a "special" one in that it goes to the max. clock speed, and never uses the min., or any frequency in between. You can do that if you want to do benchmarking reliably, but I'm not sure it's good for battery life.
http://forum.xda-developers.com/showthread.php?t=1663809
^ That page explains all the governors, but from what I can tell from using Cool Tool onscreen system info app, "lagfree" on Doomkernel seems to be a higher performance governor like you'd expect from the name and not how he or she describes: it seems to scale down only quite slowly from a high clock, I'm guessing to eliminate any possible lag while scrolling the interface that might result if it scaled down quicker. And we don't have anything relating to multiple cores
Anyway, I think I saw you say you were on JokaWild as well. Looking at the Joka init.d scripts the SmartAssV2 parameters are tweaked towards performance and it comes as the default for the rom, so maybe try that as a more balanced option than Performance governor.

I wondered as well if v14 was not as good as v13 3013 for battery life, but better for performance, but 5% in 10 minutes is a lot. Have you tried using the BetterBatteryStats app to find an explanation? Has it got better just through subsequent use / recharging?
Battery life really sucks on jokawild (actually in all CustomRoms).
I have mine like this (r800a):
-smartassv2/sio or bfq
-.62 stock rom with a couple of build.prop mods
-64 baseband
-juice defender
-brightness around 25%
-supercharger v6
My phone has been for like 4hr and still with 100%

Was it charging? That's impossible. I left my phone idle,lowest brightness and wifi off for about 30 minutes and it dropped to 96%.
I have deep sleep enabled,juice defender,

Which governor settings will yield the best battery life

Right now, I am running DH's Google Play edition rom with Sky Dragon kernel. I am running it on the interactive governor. Battery life is Meh. Definitely not as good as sense.
Which could governor/settings will give me a good mix between battery life and performance?
Interactive is never good on battery. Its smooth but its a batt hog. Intellidemand, on demand, abyssplug are great on batt life. Use noop or sio as scheduler.

Interactive is the best Gov IMO. Its scales way better than Ondemand where it just jumps to the max. I've tried out all Govs and they yield just about the same with like ~5% battery difference. I would install better battery Stats and see what's hogging your battery (wakelocks). My guess is Google Play services. If you use Xposed there is a module called Unbounch that helps with wakelocks. I use two apps to stop many Google Play Services receivers from running.
