Advice please. - Nexus S Q&A, Help & Troubleshooting

So ill admit.
I am an advanced and knowledgeable noob.
And I am very capable of soft bricking and fixing my own problems usually
But the only thing iI haven't learned.
Is kernel management.
I don't understand VERY WELL how to tweak setcpu
To extend battery life and maintain good performance.
I use profiles to underclock while screens off.
While battery is low, and while charging.
But I don't get what the voltages option menu is about...
So I was searching a "how to" tutorial on the process and terms and what not.
And found one that was as useless as an ass hole on an an elbow. (Kill bill joke)
Anyhelp?

Dont use setcpu...use nstools from market and it is free..
Nexus s custom kernel will usually will drain morr battery if you use profile..
If you want to get stability,good battery life,my advise is...flash custom kernel(ex. Matr1x) dont UV, use gov lazy or ondemand,minfreq 400mhz,maxfreq 1000.dont use profile..for now just disable deep idle...believe me..after 3 battery cycle.
You will get good battery life...

How do you enable deep idle? I thought that was a set by default thing?

Just use Matrix kernel and you wont have to worry a thing, definately gave me good battery life. Good luck

Myns Warm 2.2 question

So I have Myns latest Rom and I was wondering about adding Setcpu to the Rom. My question is this. For those of you that have this rom, how is your battery life? Do you use Setcpu? Is it compatible with this rom? Should I leave it as is? I dont want to overclock, I just want to underclock when display is off to save battery. Any expert advice?
What kernel would you guys recommend? Again I dont want to make my phone faster, I just want decent battery life, and I know there are a couple of tweaks I can do. ( and yes I already know about the brightness, wifi etc)
Getting bad battery life too huh? I'm new to this rom and I'm trying out a couple combos. I have setcpu to underclock using smartass. I changed my kernal to one with more havs. I'll report my findings.

No I really havent gotten through a whole day with this Rom, so I cant say I have had bad battery life. I just wanted to know what you guys are doing and using out there.

I haven't gone a whole day either. But I will today. I will let you know how my battery does.

Im using Netarchys 4.3.1 toastmod CFS HAVS nosbc and I can average 15hours with standard use, 24+ hours if i ignore my phone all together.
I use SetCPU and Juice Defender (it turns off data when my screen is off) and i easily get a day of battery life, my minimum is 12 hours and that is if I am constantly using it
I have been using Myn's 2.2 with the netarchy 4.3.1-cfs-havs-nosbc kernal for a few weeks. I have Setcpu profiles to overclock ondemand at 1152 until my battery gets to 30% then runs at 998 after. Also have it underclock at 245 when the screen is off. I can easily get a full day with several texts, a few hours of surfing, a few phone calls and maybe an hour of games (Angry Birds, Let's Golf). Usually plug it in at the end of the day with at least 20% battery left.

Setcpu?

Anyone here try setcpu on your Galaxy S 4G?
I'm sure there is some "new and improved software" reason to not need it, but I figured I would try it to see if I could improve battery life in some way.
I'm still tinkering with the settings, but I think I have noticed a slight improvement. If you try it, don't set your screen-off speed to any lower than 400mhz. If you do your phone will slow to an unimaginable crawl, sometimes only to be recovered from with a reboot/battery pull.

You can use it but until there are custom kernels that allow you to underclock or overclock its gonna be a lost cause imo. At this point its only good for changing governors and possibly screen off profiles and things like that

Can't wait for an Oc kernel

It already hauls once I removed bloatware, my system is pretty "bare bone" now, and it's FAASSSTTT.
That being said, one of the main reasons I upgraded to this phone from my modded HTC HD2 was the battery life was horrible on that phone (comparible to an evo 4g as per many side by side tests with a friend who had a new one).
Battery on this phone is GARBAGE, basically the SAME battery life, maybe only slightly better if at all....
I thought technology was supposed to be improving. I mean I abuse the phone, It's my sole entertainment while I'm at work (I work at a call center). I'm doing things on it 24/7.
But I figured it would perform better than a non-native android phone, modded to run android, that's two years old.. (htc hd2)
I have been using an app called tegrak overclock. it seems to work great for me.

You can overclock without overclock kernel?

I just use setcpu to disable auto scaling..

TegraK seems to work. It's an "on demand, on the fly" patch that isn't persistent.
I see improvements in benchmarks and reads/writes. So, it seems to work. Every time you reboot though, you have to reset it.

Overclock

Hi all. I have rooted my phone, now i am wondering what overclocking my phone would do for me?
Is it even worth doing it.
Sent from my Gummy Charged GBE 2.1 using XDA App
Depends what you're doing with your phone. If you OC your phone will feel smoother, but your battery will take a hit. Its probably not worth it unless you need the performance.
Sent from my SCH-I510 using xda premium
I'm more apt to undervolt the phone than overclock it. You don't lose performance, and you gain battery life. It takes some patience and experimentation to find the voltages that work best for your phone, but it's worth it for the battery life gain.

Battery Life test Results

I was pretty pleased with my results here, so I thought I'd share. This is done with both OC and UV and making use of the the 3500mah batt and with moderate/normal use.
I can get that on stock battery, you must play some games and leave your phone on full brightness at all times or something.

No, I play one game in particular, and I spend more time on the web on my phone than most people do on their computer. I could get that on a stock battery too, if I never actually used my phone Before the the changes I made, I was getting significantly less life. Especially with OC.
It looks like the moment you turn your screen on your battery life plummets.

Thats from Oc'ing to 1560 lol
It's more useful to post test results on a standard battery and standard voltages and clock speeds so others can compare. I've gotten 3 days on stock CM7 nightly before, it really depends on how much one uses their phone. The biggest clue to how a ROM or kernel affects battery is to look at the idle drain (maybe with data off too). It should be flat or with < 0.5%/hr drain.
Where'd you get the 3500 Mah battery you are using? I've been trying to find a decent maker for one.

[Q] RUU Battery?

Will the battery life time be better, if i flash the official RUU and turn the device S-ON?
I have got an anker battery.
no undervolt, no underclock means not so much battery life.

I think it will not be better. Probbably (a little?) worse.
The thing is, custom kernels have a lot of new features and can be customized to the optimum settings according to your usage. Thus perform better and longer.
See my sig for faux kernel, which I found was best for my needs.

If I might make a suggestion, have you tried a slight under volt on your CPU? This can also save quite a bit of battery life. You must start small with the under volt, then lower slowly to see how your device handles it. If no reboots and it's handling it well you can slowly lower the under volt. Only to what your device can handle. Then you will see a marked improvement in your battery life. You can do this in corporation with the new kernel you are trying. It will make a significant improvement for you. You can do this through CPU tuner or like application. Many people find this method greatly improves their battery life.... it is a viable option for a significant difference.
