[Q] just got the Nexus S 4G. should i stick with stock?

Hey everyone, i just upgraded to a Nexus S 4G this morning from the ol samsung transform, and i was planning on applying cyanogen but then i messed with the phone a bit, did root and restored a couple of my game apps...it seems to work with very nice speed, only serious issues ive noticed are just with the signal, sensitivity of keyboard, and i havnt had time to see battery life yet..
But i was wondering, since the stock rom is so clean and fast, why are we putting on different roms like cyanogen?
More importantly, as far as kernel, whats the best kernel right now for nexus 4g? im running stock kernel, but naturally and ideally id like even more speed(not sure what id use it for, but always nice), better battery life, and better data signals..
ive been reading about overclocked kernels a little bit and such, so basically im wondering about what you guys would say to all this? should i change rom &/Or kernel? to what? why? does overclocking at 1.4ghz like these kernels say have any negative side effects? things like that.
Thanks for your response!

There are quite a lot of things that can be changed by flashing a custom ROM. Cyanogen is reported to be more responsive than stock android, and a slight improvement on battery life and performance. Also, with other ROMs like MIUI you can completely change the entire GUI basically. The lockscreen becomes changeable by one click in the themes app. I've also noticed a slight improvement in battery life/performance and responsiveness.
Also, with regards to kernels, they add extra features (like voodoo sound, BLN notifications, UV'ing, OC'ing, etc). Now if you're looking to overclock your CPU AND save on battery life then that is probably not going to happen. If you OC the CPU you'll as a result draw more battery power when it reaches it's peak. Hence why I went with the TEUV88 kernel. This kernel undervolts the CPU yet manages to give me the same performance as the stock kernel. It runs extremely nicely and the battery lasts me about 24-30 hours on moderate usage where as before I was getting around 16.
Hope this helps.
Edit:: note that both undervolting and overclocking can be dangerous for any phone. The kernel developers put their kernels through testing though to ensure they are stable enough for most people (I hope anyways). But be aware that it is possible to damage the hardware be either of these methods.

yeah im looking at more undervolting for battery life cause current performance seems great for me as of this point. but i mean cyanogenmod doesnt change much since its built on gingerbread, its just slightly more customized, but on the actual performance side, it is a slight increase? so whats the best kernel for undervolting and still getting stock performance or more? im guessing its the one u just mentioned? cause i saw a voodoo kernel or something on main dev page and itwas undervolted and OCed to 1.4 i think...idk.

Yeah you might be talking about the matr1x kernel. It ocs to 1.44 and is uved also. Plus has voodoo sound, bln and bld. Some people have issues with cm7 and some don't. I really don't like the look of miui so I can't say for it. But I use decks 1.3d with zero issues and matr1x kernel with zero issues along with heavy use 4+ hrs screen time in over 12hrs. Personally running 1.44 your phone will prolly lock up but I run 1.2 non stop no freezes or lockups or reboots. Try them and see qhich ones fit you and what you like.

I'm still on stock with mine and honestly, I don't need anything else... i get 12-15 hours of moderate use and i don't really know what lag is because i never experience it with my phone.

The above posters are correct in everyway. I mean it definitely comes down to preference. I was averaging about 13-15h on my stock kernel/rom but my phone would be basically completely dead.
I switched to TEUV88-rammstein2 (Trinity Undervolted rom). It has Voodoo sound, BLN (backlight notification), and with todays update it has touchwake mod. So as you can see my phone lasted 15h (still with 35% battery left) with 3h of screen on, and 45m of audio streaming, and lots of texting.

What Kernel best for CM7?

Hello I am wondering whats the best kernel for battery life on CM7 would it be faux or stock? And plus can I just install the faux Cm version start at 1.0 ghz to 1.4ghz, so by overclocking it means it will have less battery life? Could I just install that kernel and leave it at 1.0 ghz? And is the faux kernel better than the CM7 stock in terms of battery and what about performance?
New to this stuff!
Thanks people!

What CM7 are you running? It makes a big difference. Also, battery life is different for every person. So to say one kernel is better than another is based on your use. Now I did notice a difference in battery life and performance when I flashed Faux's kernel. But best advice? Wait a couple days on stock, see how it is. Then flash Faux's or the any other kernel(as long as it CM7 based of course), to compare the results. Of course when your comparing make sure your phone usage is the same, or as close as you can get it

Ya. I flashed the DS OC/UV v.0.4.8 first but like faux says the battery readings were crazy, going up and down all time, I didnt know how much battery I had left. And this was after I calibrated my battery of course. Im using the CM OC/UV v.0.4.8 kernel and its great! Great performance and awesome battery life! Right now I got 38% left with moderate to heavy use on 10 1/2hrs. I posted a few screenshots of my battery use using Battery Monitor Widget Pro. I couldnt post the battery use one cause I rebooted my phone a couple times changing my theme. It reads like 2hrs on battery instead of almost 11. Also I posted a Antutu benchmark score as well. Try one see if it works, no two chips are the same, if it doesnt, he's got 4 different kernels. Plus there's the other kernels that I havent tried yet. Hope this helps!

Overclocking will reduce your battery life but increase your phone's performance. Use an app like SetCPU to choose your clockspeeds and voltages. I don't recommend messing around with voltages until you're much more familiar with over/underclocking.
I've used faux's kernels off and on and never been able to get my G2x to be rock solid stable versus the cyanogenmod kernel but it certainly did increase my battery life by a noticeable amount. Right now I'm running the Trinity ELP kernel and undervolted it even further and I've had absolutely zero issues. If you try faux and don't like it, give Trinity a try.

I prefer Trinity ELP or Faux DS versions if I am in battery savings mode depending on the ROM I am using.

Best Rom with Battery Life?

Hello,
What is your best Rom which have a good battery life?
Thanks!

you need to try yourself, because it depends on your kind of usage.
however, you can look around the forum, there are some very nice threads benchmarking the different roms/kernels/governors/etc...

For me it's nuhetri-reloaded + Air Kernel 3.4.5 using smartassV2+noop scheduler

This is my current set up (check signature). Its been the best so far with battery. I can leave my phone off for 6 hours and loose 1-2%. The performance is pretty damn good too, very smooth and quick
Nexus S (GSM i9020a)
AOKP (Build 27)
Air Kernel (3.45)
OC 800/100 (Lionheart)
Live OC 105

Seems like air kernal is quite popular atm.

if you want a Gingerbread ROM then do koush's ROM
http://forum.xda-developers.com/showthread.php?t=1091153
But if you want an ICS ROM then do SLIM ROM
http://forum.xda-developers.com/showthread.php?t=1495652
Just dont mess with the kernel.... I used the GB rom awhile and now this ICS rom... both get all day life and I use about 3 hours a day of surfing the web, about 2 hours of playing music and some games. Both have great idles that dont suck up battery life. Just be careful of some apps that drain batteries.... so try then bareboned then try with the apps you want. There will be a difference so play with the ROM to see what is best for you and ur usage.
Just use the notification bar to turn off internet, wifi and gps when not used.
good luck

I get pretty good battery life with vhgomez Lota r1 + Matr1x cfs 17.5. Averaging about 15-16 hours with medium use(about 2 1/2 hours screen on time).
Usually at 200/1000 with Deep Idle and either SavagedZen or Lulzactive.

I must say...BuglessBeast is treating me EXTREMELY well so far...I start my day at 4:00am, I don't usually plug in to recharge until around 10:30-11:00pm....
Very good lifespan... before custom ROM, I was recharge before dinner almost every day.
I'm VERY pleased with this ROM.

[Q] Battery saver kernel for Sensation

Hi!
Ok, i'm not good in writing especially in english so here we go
From all kernel that has been released lately, which one do you recommend for having the best battery life in term of standby??
My opinion is Sebastian's kernel in ARHD 6.5.1
it gave me mostly 2 hours for 1%
but i have new problem now cause i flash ARHD 6.5.3 and then restore boot from 6.5.1 NAND back up and now my wifi gave me error
(but this is my problem, not yours )
Come on guys, give me your opinion

I'm currently running Hyper NonSense with the default kernel - I think it's Faux that's cooked into the ROM but unsure of this. Between the ROM and the kernel, I'm getting the best battery life I've seen with this phone. Easily have 30-50% left at the end of the day with moderate use; haven't actually benchmarked it more carefully than that.

Any update on this? My sensation doesn't even last a day...

Best kernels right now are Faux kernel
Sebastian FM
Bricked kernel
I myself have found that bricked uses the less battery, but try them yourself and decide which suits your needs.

I'm using Faux right now with HyperNonSense and I would say it's a good balance between battery saving and performance. One thing to keep in mind is that the higher you OC the more juice it'll drain. So far I've always capped my CPU to 1.24Mhz and I've never had an issue with performance. During light use I can get more than 30 hours in a full charge. If it's a moderate use, I'm still able to touch 24 hours. Oh yeah I'm using Anker 1900mAh.

[Q] Best rom + Kernel for battery life??

Hey, Just wondering what would you guys say is the best rom for + kernel for battery life that also isn't stupidly slow.. Oh and by battery life i don't mean like upkeep time i mean like basing it on screen on time like what roms can get 4+hours screen on time?
Cheers

stock rom 4.04

Oh and what kernel is better for Rascream rom Trinity or Matrix cause i don't really know much about rascream as i just started using it.

I'm able to squeeze over four hours of screen on time from most ROMs providing I don't reboot and minimise my modem usage. I'm currently using Pete Alfonso's Gingerbread kernel and Blandriid 2.3.7.
But I keep trying alternatives...

Yeah Atm i'm using latest Rascream with TEUV kernel and not sure atm but battery seems okay?

The biggest battery eater is the screen so try brainmaster's black cm9. It's about the only thing you can do apart from obviously keeping your screen brightness at minimum is put your phone in airplane mode when feasible. Nothing else will make much difference.

For GB i have to say, Oxygen 2.3.2 with Matr1x 11.0
As for ICS, i've yet to come across one, I do, however have fond memories of aosp+

To supplement bedalus' post: to base battery life on kernel+rom combination alone does not tell much of a story. I got the most out of my battery when I - used a pure black and static wallpaper, turned off auto brightness and manually tuned down to 10%-ish, kept apps and processes at a minimum (reduced app drawer to a single page, mostly stock). To reiterate, kernel+rom alone give few tangible differences when comparing battery life, from personal experience.

I use Matrix Kernel v19 and CyanogenMod v7. 24 hrs with light use, 12 hrs with heavy use.

used to use milestone 4 with air kernel.
use the latest version of both rom and kernel and set 200-1000.
you will see the difference and if you want to save more battery after following as above, then reply me.

I haven't really noticed a difference between ROMs. As stated a few posts above, the kernel and ROM themselves will only give a few minor boosts. Black vs white screens makes a world of difference. I use the inverted browser a lot and a majority of my apps tend to have dark themes which I personally prefer. Daily use, 3 or so hours of screen on time with the phone off the charger for 12-14 hours. It all varies on how I use my phone though on that particular day.
