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.

Definitive best kernel/rom combo for battery? NS4g

I use my ns4g pretty heavily so I need a rom and kernel optimized for battery life. I'm looking for 3+ hours screen on time, something the ics roms/kernels I've had havent quite delivered. i dont wanna downgrade to gb, but I'd like to find a good combo of battery life and stability...

try this ics kernel, http://goo.gl/QAuKi its Trinity TEUV(TEI6S). its undervolted, underclocked at 880mhz, and its bus/gpu is overclocked 10% at 220mhz. its fast and great on battery. i use it with cm9, but it should be good with any ics rom

You don't even know lol ive tried and tested that decent battery but I can't live without the mods... solid performance tho

With all the mods, they r all good as well (icup speedy, matr1x, sg-uv etc.). The new franco.kernel is released and it runs very nice. It doesn't have mods yet but the battery life and performance are super. Also like simms said, the barebones trinity kernels are the best in battery life.
I'm running NexusBeam with franco's latest and I got like 25 hours of battery after average use.

TEUV All the way for battery performance

Matr1x v15.0 is out, has all the features and is undervolted.
I get 20-25 hours out of battery with around 4-5 hours screen on time.

Do you think using running CyberGR-MOD|NS.NGN ICS with Matr1x 14.5CFS, i could get decent battery life? i'm asking cuz i want to install ROM on Gf's phone, she still running CM7 from when i did last time, but i don't want to put a rom that lacks features. i want one feature rich that will not suck on battery life

I can't get over 2 hours screen on time MAX at all anymore. I'm running Peter Alfonso's Bugless Beast GB with GlaDOS 1.12 kernel undervolted to 880 MHz and 20% screen brightness. Even with a new Battery and a full wipe and clean install I still get terrible battery life. Anybody have any ideas? I'm dying here. Is my phone broken?

Most recommended rom/kernel question

What is the most recommended 2.7 gingerbread rom that offers great battery life even with hard cpu usage.
Also do kernels that offer the same speed still differ in battery life consumption? and could I get one recommended plz
Thanks

I'd recommend either singh miui as is with the stock cm7 kernel it comes with, or eagleblood 2.7 with morfic's trinity kernel, you can either use the ELP version which OC's to a max. of 1.1GHz and is more battery friendly (i.e. undervolted) or the T15 version for higher OCing which is still pretty good for battery life.
I'm personally using eagleblood 2.7 with T15 trinity kernel.
P.S. of course all other roms, and kernels, available in the development section of this forum are great and each has it's unique touch. Ultimately, it's a matter of personal preference as well as what works best with your device seeing as to how performance fluctuates so much from one G2x to the other.

From my personal expetience cm7 nightly + faux kernel give the best battery live. I've tried Trinity and it is pretty good but lasts 2-3 hours less, at least for me

Best Combination (Kernel + Rom) For Best Battery Life (Q)

Hey guys, atm i use the CocaCola rom and the kernel that comes with it i think is fauxs kernel.
My battery life is pretty harsh and is down to 30% by like 4oclock everyday so i gotta charge it again
I'm just wondering what kernel and rom u guys prefer for the best battery performance
i realize the rom doesn't effect the battery life but just throw out which one u guys prefer

I like the faux kernel but its not really a battery saver unless you underclock and underovolt it seeing as it is overclocked be default. If you use things like bln then the "stockish" kernel has those features. Or you can flash the stock kernel over the rom which will give you good performance/batt seeing as this phone is no slouch by default. I fiddle back and forth.

I under clock mine close to 1000ghz and it still smooth as ice

Which Rom Do you recommend for good battey life

As the title says, Which Rom Do you recommend for good battey life and a Bit performance too ?

Honestly I'm pretty happy with miui sense based,I get pretty much always through the day with pretty good use.

For battery life? isnt mdj's kernel overclocked? (GPU&CPU) Stock better i think.

Yes, it is overclocked but it can be lowered to 1.5 and has been tweaked to provide better battery life.

And its also known to corrupt internal storage

But GPU have to stay overclocked

I haven't experienced any corrupt internal storage issues with the kernel. I suppose that is part of the risk with flashing anything though.

You can always flash back to the stock kernel. I was also a little worried that OC'n everything would drain battery like crazy, but I easily get 1-2 days out of my phone. The biggest battery drain comes from the screen. If you're playing a game, browsing the internet, or anything else that requires the screen to be on while using the device... it doesn't matter if your processor is unclocked to 800Ghz, you'll only get a few hours (3-5) of battery life. There is no rom or kernel that is going to fix that.
If you think about it, overclocking the processor will allow you to do things faster and minimize the on-screen time.
