Hi, my Triumph should be arriving in the mail in just a few days and i was wondering which is the best kernel or ROM and Kernel combination that is best for battery life? I've heard that battery life on the Triumph is not so good. Maybe it's false but i would still like to know.

I would go with CM7
That's what i was planning on. Does your Triumph give you battery problems?

The battery life is a lot better now with the latest builds of CM7 and MIUI.
I just use CM7 and leave wifi and bluetooth off, no juice defender or anything like that and I can easily go all day with no charge, typically about a day and a half and my battery is getting low but it really depends on what you are doing like games, wifi, videos and whatnot.
Before I think there was a problem with the battery draining while in idle but things have cleared up since then, There are also third party kernels you can OC and everything, but you can use them to undervolt as well to save some battery if you know what you are doing. over on androidforums there is a lot more chatter about this phone, just so you know.

Thanks. I got my phone today and im loving it so far. Do you know which of those third party kernels are good for battery life and that i can install over stock? I'm not quite ready to install a ROM yet but i already did the HTC Thunderbolt Build.prop tweak and obviously im rooted.
It's usually not the kernel but whatever governor you have it set to use. Even the stock can get improved performance if you switch the governor to such--”performance”--but I'm probably not the guy to tell you about which one is best.
I also have the silly feeling a lot of misconceptions abound here...in the form of ”I changed this setting and now my device lasts longer..., oh btw I no longer play with it 24/7.” In other words, use drastically impacts battery performance. JuiceDefender is an amazing tool but it won't do you a bit of good if you're testing out your phone's Adobe Flash capabilities regularly.

The Savagezen and interactive (not sure if interactive is on any of the kernels for this phone.) gov isn't that great. At least not in my experience. I had SmartassV2 on my girlfriends phone and it got ~3600 on Antutu benchmark at 1.5 and when I used Savage at 1.5 she got ~1700. The interactive gov made my friends Dinc2 noticably slower. Just switching home screens it lagged to the point it was hard to get into the app to change the gov.
CM7 + TheOC kernel allows adjusting voltage & overclock or underclock. You really should flash a CM7 ROM. Having it just rooted can be dangerous because you're not using a custom recovery to make a backup image, and if something messes up, you don't have a backup ROM to restore. Going to a different ROM forces you to make a backup, then there's a backup to restore if you mess things up.
Governors just tell the CPU how fast to ramp up to a certain frequency, & how long to stay there. It's hard to balance fast ramp up (less lag), and low battery drain (spend more time in the lower frequencies). I like interactive/x, find that smartassv2 spends too much time in the mid frequencies (~500) even for light work. Using the app CPU Spy helps a lot to see what's going on. Also it tells you whether your phone is sleeping properly when screen is off, which is a big factor for battery drain.

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.

I am playing a bit with underclocking my DS (Using UNITY v4 kernel atm, will update to v9 later).
However, I'm figuring out the usefulness of it (to extend battery life mainly).
Does it really save battery life? I'm already using JuiceDefender, and its SetCPU function.
Or is it not very useful since the most batterydrain comes from radios anyway.
What are the best values for it?
What's the standard clockspeed for the DS? And what is the best Max IDLE clock speed?
Well, i wont underclock at all.
First of all there is no need to do that to get good battery life. You can do lot other stuff to do so.
Under-clocking is risky as it might now have enough power that needed to the phone. that means that some stuff might not get processed like calls and stuff.
Right now with me using miui i get life for about 3-4 days.
Standard clock speed is 1,000mhz.
I have mine underclocked to 600mhz during idle times and it's perfectly fine.
Never had any issues at that speed and it keeps my Desire S much much cooler which can only be a good thing.
As for it's ability to extend the battery, I don't think it does so much in my case. I typically run WiFi overnight and G/3G/H during the day and my display usually chews up 60-70% of my overall battery usage even on a very dark screen.
I'd pick a setting that you feel comfortable with but have low expectations of the benefits.
The only time I use underclocking is for using Google Navigation.
On a hot day using Navigation for over a couple of hours, my DS would over-heat and restart (usually as I was approaching my motorway exit). So I have Tasker dialing back CPU to 768Mhz when using Navigation, and it does seem to help the phone run a little cooler. I no longer have to take it out the case for example.
Using the smartass governor (I believe) automatically knocks the CPU back to 240Mhz when sleeping. Not 100% on that though.
I'm currently testing a new kernel, and I spent an entire charge cycle on 'Smartass' and then an entire charge cycle on 'Powersave'. Aside from lots of lag on the latter one, the battery life was pretty much the same!
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!"

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
I was wondering which CPU settings / governor everyone else is using on their Skyrocket. I'm running the official CM9 nightlies, and am currently using a 1188/384mhz combo with the conservative governor. Battery life is OK, but isn't as great as it was with Sky ICS. I'm wondering if anyone has any suggestion on how to improve it.
Thanks!
i suggest you use the app set cpu. with it you can make profiles that change your cpu level depending on factors like if your screen is off or if your phone is charging. it really helps with battery life

it all about the $$$$
lets see what it will cost me i have a thrill, a sr , do i need another phone ..yes!! but i also need other things too. like food and gas it all about do i have extra capital to drop an a new toy. my partner at work still has a unrooted g1 it makes me sad.
Try testing this:
http://forum.xda-developers.com/showthread.php?t=1721235
I currently have mine on 192/1512 will see how it goes testing it for a full day but so far its a little less draining than the original (at least for me).
Hi all,
I have been using the ONDEMAND CPU governor for quite a while on my SGS4G running CM9 (Team Acid's version, the final herring one), and I have just gotten used to the 12-14 hour battery life that I have had ever since I switched from GB back in August 2012. However, most of the frequent users here recommend the SMARTASSV2 governor, so I tried to use that yesterday to see if battery life was enhanced.
If anything it seems that my battery life got worse (see attached picture). I am a moderate phone user in general; I use my phone for texting mostly, and sometimes I'll look something up on the Internet, but no music, WiFi and GPS are always turned off, no overclocking/undervolting. I recently purchased a new battery as my old one died about two months ago.
I was wondering, is there any governor for the CM9 ROM that is particularly good with battery but doesn't completely drain performance?
(Also, I tried to use the LZ kernel before, but it seemed to cause many more problems than it fixed.)
You've got some pretty bad wakelocks going on there. See how your phone is awake even though your screen is off? That is an issue. Also how much screen on time did you have on that run? Get Better Battery Stats(free on XDA) then fully charge and look at what wakelocks are occurring. You might also want to consider UVing if you want better battery life.
Also, if you're a fan of ondemand, I highly suggest moving to ondemandX, which actually does deep sleep when the phone is off.
But that will only help if you fix the wakelocks first. So follow hechoen's advice and your phone should be way more awesome.
Downloaded BBS today, we'll see how it goes.
