Undervolt Kernel without lack of HSPUPA? Or battary reduction options?

Hello I have run both the stock cm7 and cattleprods 4.3.1 with smartass
Even going as far as to use SetCPU profiles to reduce CPU to 245 min/Max on screen lock. Im able to squeeze 11-12 hours with decent usage
from what I unslderstand reading the lord UV kernal people are lacking hsupa which is something I rather like. And while im ok with 12hours usage if something unexpected it long dinner party after work, im SOL
Any help or tips would be great
Thanks

HSUPA seems to be hit or miss on the LorDmod kernel which is strange because it's based off the CM7 kernel by Kali-. I changed my APN and my HSUPA speeds came back, at least what's normal for me in my area (3.5mbps down/2mbps up).
I was pulling a little over 48 hours out of the -25mV undervolt BFQhs version before it needed a charge or it wouldn't last the next day. I'm currently running the Pinky Ultra Undervolt version and will see what kind of battery life I can pull out of it.

Wrong forum for this. It should be in general but the lordmod kernel probably isn't the hsupa killer it was probably the radio swap I did. I fixed it but it was a PITA!

Can I get a little assistance? I read throughout the your thread and the one u linked. There are about 15 different kernals and UV zips
Thanks. Im really interested in trying this out

Do you just flash the lordmodV4.4.1-BFS-BFQ.zip file in recovery?
What do you do with lowervoltages-25.zip?
Thanks for the assistance this will be my first UV type kernel

Wipe Cache and load the 2 .zip files just like a ROM. Hopefully you won't lose HSUPA like I did (I still think it was the radio swap but I refuse to try this again as it was a pain to fix).

Sounds good. Ill report back with my findings regarding the HSUPA and overall batt improvements.
Thanks

I'll tell you the -50mV kernel mod froze the phone numerous times when opening an app to where I had to pull battery. The -25mV mod didn't help at all for my battery life. My phone drained same as always which is terrible but not great either.

I'd say go with BFQhs CFS or the V(R) I/O flavor (edit: scratch that, looks like he pulled the VIO one until tomorrow), they're supposed to be faster than the others. The non-undervolted kernel might give you fine battery life so there's a possibility you won't need to undervolt at all. Also, flashing an undervolt patch is optional.
Unlike Mustang, my phone responded extremely well to the -25mV but seemed to go back to typical drain when I switched over to -50mV. And it seems like it's enjoying the Pinky ultra undervolt so far. Like LorDmod says, try them out and see what works.
Flashing the kernel's simple,
Do a backup
Reboot in to recovery
Clear /cache
Clear Dalvik cache
Install kernel zip
Install undervolt zip (optional)
Reboot and enjoy

This is just my experience - during extensive testing for my APN modification thread I ran multiple versions of lordmod and never lost HSUPA speeds from the kernel itself. Any loss of speeds were due to other issues which were identified and corrected.

Yeah like I said I'm 99.9% sure it was the change in radio that did me in but it just so happened to be just before flashing the kernel and I didn't notice till the next day I lost HSUPA. I personally will stick with stock CM7 kernel just because I messed with my own head lol.

I just flashed the kernal last night with the -25. HSUPA is still intact. Ill report back on Bat life

I have only tried -50mV with the latest LordMod which after 2 days is giving about same battery life as stock CM7 (about 20-24hr with moderate use). I cannot explain how -25mV gave you better battery life. I don't understand how much the other 2 version undervolts.
As a whole now tried OC/UV on both the Captivate and the Inspire, I have not noticed a significant difference in battery life with either of these phones. Also it seems like all the ROMs give me about the same battery life, and the whole thing about re-calibrate your battery if you don't flash with a full battery hasn't held up for me either. I can flash a new rom with 30% battery or 100% my battery drain remains unchanged.

My experience mirrors yours. No matter where my battery is when I flash a ROM the drain remains the same. I've also done the whole wipe of battery stats and no difference either. It lasts me long enough as I charge it overnight anyways while I sleep so oh well I'm not too worried about it anymore really.
I recently removed the battery percent from the status bar. All I ended up doing was obsessing over it and had to see where it was all the time. So now I just use the gauge and feel better about the battery lol and not even focus on battery too much unless I'm away from my charger for an extended period of time.

I use lord mod 4.4 and I have hsupa. I never lost it.

That is because your device can't handle it, every device handles it differently.
As an example, my device handles UUV fine, but when attempting to use PUV it boots, but with any random reboots and application FCs.

Trust me, it makes absolutely no logical sense to me either. It seems to really like the PUV version as well so I'm not complaining.
For me, there is a noticeable difference between the stock kernel and undervolting. Stock CM7, my phone drains at around 3% per hour. Undervolted, it's slightly less than 1% per hour and possibly even better with PUV.

With the CFS BFQhs and -25 UV I got another hour and change. I feel like I used it the same maybe more. Im gonna try another one of his kernel and maybe the -50 or UUV see if NY device can hang with it.

WellI've had x99's kernels recommended to me several times whenever I've jumped back to froyo.

Currenting went from Tiamat to ScarySUV, Tiamat seems high in performance but ScarySUV saves a little bit more battery.

Stock CM7 kernel max CPU at 1.5GHZ, min CPU 200mhz, runs great.

Right now I'm loving Scary's kernels. His links in his post are dead though .

I'm still on sparksco's kernel, but I also did noticing a couple more hours out of battery life ocerclocked to 1.5
I found that strange but nice. Phone tends to overheat though so I keep it at 1.2
Imo, sparksco's kernel is the besy by far with performance and battery life.

yeah ill usually get about 20hrs. Moderate usage. That's with 3g off and wifi on.
Best I got was 34 hrs before.
ScarySUV doesn't really help my battery life. But I never wiped battery stats when trying that kernel. I might do that and see what I can get.
When I'm on sparkscos kernel with 3g on all day, the worst ill get is about 10 hrs with heavy usage.

I get the same with sparks, scarysuv gives me decent about with amazingly heavy use but battery stats never done so I'm currently stay at 35% for about an hour and a half now.

[Q] Battery efficient rom+kernel?

hi
sorry for being such a nooby mcnooby-pants
but i just want to know which combination of roms and kernels will give me a great battery life and at the same time i want to be able to overclock to 1.5 GHz
i looked through the forums and i did all the basic stuff like
undervolting
setting profiles in setcpu
and removing all the bloatware from the phone
but everyone has a different combination and im really confused as to which combination to use
right now im using eaglesblood 2.3.7 with the dragon kernel and its really not working very well
so any and all help will be appreciated
thank you

My opinion:
1. Jump on a stock-based ROM with stock kernel and UC (underclock to 900-800 Mhz, you would be surprised you notice very little change in performance). Most stock-based ROM users report back great battery life.
2. Jump on a CM7 Nightly 199 or higher (Reports of great battery life, I can attest to this) with morfic or faux123's kernel (I prefer morfic's) which you can undervolt easily with Pimp My CPU (search XDA). I prefer it to SetCPU because the only profile I use is UC when the screen is off and with Tegra's DVFS CPU governor, it already does a good job of doing this. I also UC with this setup.
Delete Wi-Fi Calling (Kineto.apk) from your phone if you're not using it. I learned this from lotherius, it's always running in the background even when off and not in use. I was shocked to see the improvement.
I know it sounds stupid, but if you're in class or at work and don't need a barrage of updates on your phone, just turn off data. Most ROMs have a quick toggle setting to efficiently turn it on and off quickly and you'll be quite happy with how long it lasts. If you have to have data on or think it's moronic to have an Android phone that's not does not always have a data connection, battery drain is just the price that is payed.

woah.
Awesome answer
so do you think option 1 is better or 2?
does using cm decrease the battery efficiency?
if it does do you think the extra functionality in cm makes up for the batteryloss?
Thanks btw

Try miui 1.11.4 from whitehawkx with faux kernel cm-4.4

Good question, and I think that is totally up to you.
For example, my father and I both own G2x's, he runs a modified stock ROM (xboarder's ROM) and I run CM7. Without a doubt he gets better battery life than me, but at the cost of not having the features I have.
That may be a rough way of putting it but yes, using CM7 with all it's awesome features come with the price of not being as battery efficient.
The real question is if being less "battery efficient" actually means it's a bad thing. In my case it doesn't matter to me at all. Using the quick panel toggles in CM7, I only turn on data when I need it and I easily pull 15+ hours a charge because of it, assuming moderate usage.

Consider lotherius's tsugi rom, currently in version beta 3. It is my daily driver, stable, faster than 2.3.3 based roms, and excellent battery life. He has included a 2G toggle app that can automatically switch to 2g radio when screen is off to save lots of juice.

[Q] Which battery life tweak is better?

looking in the samsung infuse's super thread i saw some tweaks that could improve the battery life of my device. One is thunderbolt tweak by pikachu01 and the other one is Universal Adrenaline Shotv13 by dsexton702.. Which one has better results in battery life? or if i could use the two tweaks and if it would be okay? i flashed catyrom and infusion kernel about a week ago and already calibrated the battery but i still want to get more battery because it doenst last too much any other recommendation to improve this would be all right too

Try ZEUS ROM, The best battery life i have got on any infused rom so far.

Don't calibrate the battery. It does nothing to your life, I promise. Studachris posted a link to a Google Engineer saying it does nothing but mess stuff up. I'm with the guy above me, Zeus. Take the jump.

Avoid USAS - Some of the changes it makes trade off data integrity for performance (without notifying the user of this fact - probably because the creater doesn't even know what the hell he actually did). So I would avoid it.
In general, most of these comprehensive tweak scripts are bad news - very often the creater throws crap in there that they don't even understand.
v6 Supercharger nearly destroyed a few Tab Plus users' batteries by screwing around with kernel reboot-on-panic settings.
When it comes to tweak scripts - research tweaks, learn what they actually do, THEN apply them individually.
Quite a few of these are also valid for Infuse (but not all) - http://forum.xda-developers.com/showthread.php?t=1378080

[Q] Best ics battery life rom/kernel?.

Hi, ive been searching trough isc roms and kernels trying to find one with a good battery life, but there isnt, they all talk about customizations, power, performance but not about battery life. I flashed CM9 with its own kernel and its nice, but it got crashed some times when i was websurffing and the battery life gets like 13hrs of standby and 3 hrs of usage (wifi, network, display), so i went back to GB stock. im not sure if its an isc problem or just becuase of CM. Well id like to know if there´s an ICS rom or kernel that gives me atleast 24hrs of standby and a good stability.
And what about the CM9 crashes?, its isc´s bugs?
Im wating for a JB release, as it seems to be bettter than ICS. Thanks for reading , and sorry for this questions, is just that xda is the best place to find information as im a newbie in android c:

try the hefe kernal or one of the newer ones posted by team Fahq. Might help with stability.
Then flash the battery mod posted by itzik2sh. That made a very noticeable difference for me.
http://forum.xda-developers.com/showthread.php?t=1985073
I was running ultragen with hefe kernel+itzik2sh's battery mod and was getting very very good battery life and the phone was stable.

Also changing the governor to SmartAssV2 can result in great battery life, even if my phone is clocked to 1.2 or 1.4 GHz.
But if you do not understand overclocking, do not try it, I read a couple articles before I actually OC'ed my phone.
If you want performance and battery life pertaining to kernel, you can try Hefe or Lightning Zap.
Other than that, you can try tweaks around OUR forums and see the results. You can also install Pimp My Rom to install tweaks.

As to say how much battery life? Doing what? On standby? With the screen on full brightness playing GTA? Connected to data all the time?
There is no answer to that, because everyone uses the phone differently. Obviously if I say I get 2 days out of my phone and someone else gets 2 hours, maybe I only sent 15 txt messages and they watched HD Youtube off data for 2 hours while their GPS was on.

Wifi and GPS use a lot of battery when always leave on. Turn it off when u don't need it. Hefe kernel seems to help with the battery drainage issue.

Dont get mad man. About the search, ive done that, but here i can find a better and smaller answer. And about the battery,as you suere read in my first post upside i was saying in standby and a light use, and how much it lasted for me (a very short timefor a new battery). Anyways, thanks for the link .
And thanks mike y, Ill try out your combination.

I'm currently on UltraGen with Hefe-KOD kernel. Great battery life with good performance. Attached screen shots is with lite usage. Came from AOKP Milestone 6 latest build. Great battery life as well. Will probably go back to AOKP in a few days.

That battery life is because he doesn't use his phone.

Ive noticed of that, but even when I was on CM9 i got only 15 hrs on standby, either way, what thing really provides that battery life?, Ultragen or Hefe kernel?
