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.

Okay I'm planning to buy this phone and decided I am going to use CM9, just wondering what kernel I should use stability and performance is key, I don't mind battery life I can cope with charging every night as I do this now with the worlds worst phone (iPhone 3G) fully charged this morning (8:00) now 30% (17:15) all I've used it for is a little browsing and at most 2 and a half hours of music at mid volume and sent a few texts. So to wrap this up what kernel would you recommend stability ranks higher than speed but speed is important battery mind I can cope with as long as it is better than my iPhones :') If anybody already has CM9 post some screen shots :')
either franco or glados will give you the best of all worlds (performance, stability, battery). i'm not partial to either, i just flash whichever was updated more recently.

I'm sticking with Franco's since it's done wonders for me on GB.
Using it on ICS now and it's stable and fast.
Greetz
i haven't try ICS yet, but in GB i suggest FRANCO , it's damn good
about battery , it happens to all smartphones ...
only you thing you can do for hard usage is buy an extra battery or extrenal power , thank god our phone's battery is replaceble not as iPhone which is UNreplaceble...
I like mathkid. I used franco on gingerbread but i feel mathkid 11.5 ics is better on ics

Hmmm, what's it like on the performance & stability side?
i think franco's kernel is good ..
Franco Kernel hands down.
He frequently updates his kernel usually on a weekly basis as of now and contains all of the power saving tweaks (Lazy Govenor, DEEP IDLE, BLX, TouchWake Live OC ... this guy is good) created by the creator of the GlaDOS kernel Ezeekel.
He does not have any debugging tools running in the background (as other kernels do) for optimal performance.
Hello,
i'm new on the Nexus S. I had a Milestone and tried pretty much every custom rom, as the Milestone stock rom was slow, unstable and outdated.
I read many times "great battery life" within the description of Nexus S custom roms (e.g. Codename).
BUT, is it better than the stock-kernel battery-life? And how much better (guess)?
I ask, because most of the Roms are overclocked and perhaps the "great battery life" is relative to those speed-optimized roms.
For me the speed of the stock rom is totally okay and it seems totally stable. I would only "custom-ize" it, if the battery life would be (significant) better – else: "Never change a running system!"
AK
p.s. Links are welcome, as i didn't find any comparison like this.
I have found stock GB rom was a battery hog. I tried a few roms but loved that CNA will pull all your apps from the market for you(I didn't have to download them all manually)
With a custom rom you can change more settings, you can change governors, you can change the cpu speeds and voltage. With deep idle sleep working your phone sips power when in your pocket. I like the Air Kernel,3.x with the scary setting, seems to use lower cpu frequencies more often.
you can find roms that are stripped down to next to nothing, these should give you better battery life then stock, to fully loaded roms that most likely will not give you better battery life.
I have my cpu set to 200 min and 1400 max running air kernel with the scary governor. scored around 2500 on Quadrant and battery last pretty good as when I just have the screen on, not doing much the cpu is running 200Mhz and the phone goes in to deep sleep right away.
try CPUspy and cool tool, CPUspy lets you see the states the cpu is using for a given time and cool tool can display cpu/power details in the top bar.
Through my ROM testing with ICS, most ROMs give very comparable battery life. Battery life relies very little on the ROM itself assuming there is no wakelock or similar issue which is because of the ROM, which in a good ROM there won't be. There may be some settings which are added or changed that have some effect, but likely nothing very major, especially in my experience.
Normally the bloatware is what drains battery with unused apps opening in the background.
Custom ROMs omit and give the option of certain bloatware.
Also some ROMs have great idle compared to stock.
But overall if u control ur mobile data, wifi, gps and sync then u can better or great battery life on any ROM just as long as its not a newer ROM that is still testing. And most custom ROMs have the pull down notifications that make it easier to control all of them.
I personally use SLIM ICS and its comes simple enough that u customize it.
Vs Nexus S 4G
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.
You may have heard about how flashing a new ROM can improve your Android experience, but flashing a new kernel is one of the best ways to improve your phone's performance, battery life, and even add some saucy new features. Whether you know anything about either, here's what you need to know to make it happen.
What Is a Kernel?
A kernel in an operating system—in this case Android—is the component responsible for helping your applications communicate with your hardware. It manages the system resources, communicates with external devices when needed, and so on. Android uses a variation of the Linux kernel. A kernel is not the same as a ROM, even though you install them in mostly the same way. A ROM is a bit more all-encompassing. It's the operating system you use on your phone, the software your phone uses to get things done—the kernel is the bridge between that ROM and your hardware. All ROMs come with a kernel installed, but you can install a third-party one if you like—and that's what this post is about.
What a New Kernel Can Do For Your Phone
Flashing kernels isn't quite as talked about as flashing ROMs, but it can do a ton for your phone, namely in the way of battery life and performance—though it can also add extra features to your device, too. Here are some things to look for when choosing a new kernel.
Better Performance and Battery Life
This is the big change a new kernel can bring to your device. I'd separate these into two categories, but they're so intertwined that you really need to consider both when picking a kernel. There are a bunch of different kernel features that contribute to this:
Clock Speeds: In a very basic sense, higher clock speeds will improve performance on your phone. Flashing a new kernel allows you to overclock your phone, using higher clock speeds than the manufacturer intended. They can also let you reach lower clock speeds, so you can underclock your phone when you aren't using it, thus saving battery life. Your kernel will only give you the option to do so, however; if you want to overclock, you'll have to flash the kernel in question and then use something like SetCPU or CPU Tuner to tweak the clock speed.
Voltage: Higher clock speeds use up more battery on your phone because they require more voltage. However, some ROMs come with lower voltage limits, which means your phone will run just as fast, but use up less battery. Some will even overclock and undervolt your phone, though all of this comes at the expense of stability—if you notice that your phone goes into a boot loop, or reboots at random times, you'll want to either lower your clock speed or upgrade to a kernel with a higher voltage. Some ROMS have further sub-categories in this section, like Hybrid Adaptive Voltage Scaling (HAVS), which can be better for battery life (at the risk of stability) and Static Voltage Scaling (SVS), which keeps your phone at a steady voltage.
CPU Governors: Different kernels can support different CPU Governers, which manage the way your phone ramps up or down its clock speeds as you use it. There are a few different kinds you'll see, including Conservative, which focuses on battery life by ramping up your CPU very gradually when needed; Interactive, which focuses more on performance and smoothness by scaling up the CPU faster; InteractiveX, which is like Interactive but scales the CPU down when your screen is off (for better battery life); and Smartass, which is similar to Conservative but takes more factors into account when ramping up the CPU.
Task Scheduler: Kernels come with two different types of task schedulers: the Completely Fair Scheduler (CFS) and the Brain F**k Scheduler (BFS). CFS kernels are designed for regular phone use, like texting, web browsing, and otherwise multitasking apps on your phone. Most stock kernels are CFS kernels. BFS kernels focus more on whatever app is in the foreground, which is great for things like games but can be a bit laggier and a bit less stable.
These are the biggest features, but kernel developers add in all kinds of other tweaks to their kernels when possible, whether its introducing a more efficient file system, making the RAM more efficient, and so on. Again, they should list the tweaks in their description, so read up on the kernels for your specific device to learn more. I'd also recommend checking out XDA user mroneeyedboh's HTC Evo 4G kernel starter guide, from which much of this information comes.
Extra Features
Kernels can also add full features to your phone, or fix other issues that the manufacturer hasn't attended to yet. For example, while a lot of phones support Wi-Fi tethering out of the box, some—like the Motorola Droid—don't. If you find your phone isn't letting you tether using apps like Wi-Fi Tether, you might need to flash a new kernel that supports Wi-Fi tethering on your device. Kernels for Samsung phones can add support for a feature called Backlight Notification (BLN), which, coupled with an app, can turn your phone's buttons into notification lights.
Keep an eye out for features you don't want, too. For example, some HTC kernels come with a feature called Superior Battery Charging, or SBC, that can overcharge your battery for better life—but is likely to shorten your battery's life at best, or make it unstable at worst. I'd avoid kernels with this feature. You should also watch out for kernels that disable certain features of your phone—since some features are manufacturer-specific, you won't be able to get them in other ROMs or kernels. A good example of this is HDMI support on the EVO 4G.
Again, just make sure you research all the kernels available for your device, and know what you're getting yourself into before you flash. Most phones should have a large forum thread somewhere on XDA or RootzWiki that lists all the kernels available for their device. Make sure you choose a compatible one, too—the version of Android you're running determines what kernels you can use, so make sure you don't flash a Sense kernel on an AOSP ROM (like CyanogenMod), and make sure you don't flash a Froyo kernel on a Gingerbread phone—they won't play nicely together.
How to Flash a New Kernel
Once you've found a kernel you want to flash, download it to your device. It should be in ZIP format. Flashing a kernel is almost exactly like flashing a new ROM. You'll need to flash a new recovery to your phone, like ClockworkMod, which you can flash with ROM Manager. Put the ZIP file on your phone's SD card, then start up ROM Manager and go to "Install ROM from SD Card". Choose the kernel's ZIP file and continue. Note, however, that some kernels require that you flash them through your recovery mode instead of with ROM Manager—so once again, do your due diligence on its home page before you go a-flashin'.
The main difference between flashing a ROM and flashing a kernel is that you do not want to wipe your data. Wipe the Dalvik Cache only, and back up your ROM if desired (I highly recommend doing so, in case something goes wrong). Other than that, you should be golden. If you haven't flashed a ROM before, I recommend reading up on that first—but if you're familiar with that process, flashing a kernel shouldn't be a big shock to the system.

It's normal. It's just wrong reading the battery capacity in lollipop. But, actually it is 2600mAh. It doesn't matter.

I found undervolting could save up to 25% battery on my Nexus 4. I dropped it by 100mv which sounds a lot, but the device ran just as stable for I'd say 99% of the time. The only time I ever had a problem was if I started to take burst photos on the camera. I actually looked at recompiling the Camera apk to ramp up the the voltage ever so slightly.

Do not worry, it is not a common problem but I had this some months ago on a leaked TW ROM. The problem fixed itself when I flashed CM12.1.
There is no impact on battery life.
