Hey guys, I'm just wondering, after reading around the forum, it seems the general concensus is that using setcpu with a havs kernel is not recommended and that it is recommmended for use on no havs kernels. Thus my question is, for better battery life, is a havs kernal such as netarchy's bfs with havs or netarchy's with nohavs +setcpu the best for battery life?
Sorry if i missed something or my facts are wrong. Thanks in advance.
It really depends on your phone. Every kernel works differently on different phones. However, the BEST battery life (to my knowledge/experiments) can be obtained using noHAVS and the Collin battery tweak. It essentially does all the work for you (instead of tweaking SetCPU). However, Netarchy is pretty much a boss and ALL of his kernels are written so that your battery life will be awesome. It's really about trial and error with your specific phone
alright sweet, thanks for the reply

Swyped From Eva Running Myn's RLS4.95 On The Now Network!
after trying to get decent battery life for a long time using SetCPU and Juice Defender combined with other kernels I have finally ditched both of them for the Netarchy more aggressive superior battery charging 4.2.2 v2 kernel with HAVS. I have never been more satisfied with my battery life (well on the Evo that is lol).

Yeah, my phone doesn't like the 4.2.2 builds for some reason However, the 4.1.9 noHAVS and the battery tweak go together like white and rice

Alright, so I'm coming from cm 6 and I was using snap with it. But what I'm wondering, is what is the best kernel for fresh.
Thanks.

I'm running King's latest...#8 I think. Getting 53fps, 1250 Quadrant score with stock 998mhz speed. Seems good so far.
If you want great battery and dont care about the fps cap, stick with the latest stock kernel thats built right into fresh.
best kernel for lastest fresh?
I am using the kernal that came with the rom and it seems to work just fine. i thought the claims on battery life might be over rated but can say that with moderate use i got 37 hours from 100% to 15%. Might try kings again but not sure if that would hurt that battery life.

I promise you that the claims of improved battery life for the new HTC kernel are not overstated at all. In fact... there are no words to describe how much of an improvement it actually is. The theory follows that the other kernels will be re-optimized based on the new HTC kernel.
As above, stock gets the best battery life. If you need the OC/FPS/etc you can try King's #8 (I had stability issues, personally) or #6 (worked like a charm). Currently I'm using the netarchy 4.1.9.1 beta. Battery life could be better IMO, but feels really snappy. LP looks too good @ >50 FPS for me to stick with stock.

I have been running Fresh 3.2 with the built in kernel, but I've also been using SetCPU with a very low performance, battery friendly profile.
My question is whether I should be using SetCPU at all anymore, since I heard that this new kernel already supports throttling the CPU back when not in demand. I've been excited to test out how it effects my battery myself, but if someone has the answer, it would save me a week.

Even if the stock kernel does scale down the voltage to the CPU, I think you would still need setCPU if you want to OC. However, the stock kernel probably does not support OCing. However, I think setCPU could still be beneficial for keeping the CPU running at minimum when the phone is in sleep mode. Then again, that feature could also be incorporated into the new HTC kernel for all we know.
Like someone else mentioned, Kings BFS #8 gave me stability issues, but #6 works fantastic in terms of performance and stability; not to mention, everything works on my phone as it should. I got 2 generic batteries and a charger from eBay for dirt cheap, so battery life if of little concern to me.
Is there a kernel for fresh 3.2 with cifs support?
i'm kind of new to all this, only had my phone for about 2 months and this is really my first adventure out of stock root and unrevoked3.21. so i'm hoping you will be a little gentle with me.
I'm looking to flash myn's twopointtwo and improve my battery life with it. I was thinking of using netarchy's 4.03 kernel and myn's battery tweak with it, but i figured i would come here first and see what input i could get.
from what i understand, HAVS will conflict with the battery tweak or setcpu so i have chosen netarchy's 4.03(non-HAVS) for my kernel. is HAVS better than these? what about setcpu? basically, what will give me the best battery performance?
thoughts? opinions? experiences?
any input would be greatly appreciated!
Myn is good and so is HTC kernel 10. Good battery life and extremely stable. I've had tethering on so my friend at work can check the football scores. Gps enabled, I've been browsing web all day. Talking on the phone via Bluetooth. And it went off charger at 6: 30 to 8:00 so roughly 14 hrs of battery life. I'd say that's pretty good cosidering how heavily used it was. also setcpu will drain the living pizz out of your battery and the tweak makes it worse...

I really like this ROM and was just wondering if I should keep the kernel included or if there is another one that could give better performance/battery life.
Thanks!
Lou's Kernel and Ziggy's are the best imho. Lou's kernel was best on battery life where Ziggy's was best for raw power/ speed. Both give pretty good performance and battery life, one is just better than the other in separate ways. If battery is the most important (pretty awesome speed too) than go with Lou's, if you want the best speed (pretty great battery life too), Ziggy's.
The kernel from stock RLS5 gave me amazing battery life (66% after 8-9 hours of constant use on the stock battery, and same time on the 1750mAh extended got me to 74% with a 1.113gHz overclock)

I'd believe him over me... lol, I haven't used RLS5 yet. But in my experience with RLS4 it was the two kernels I mentioned.
It's the ziggy 12/19. The current one (Lou's #4) I haven't tried yet because I don't want to screw up what I have now lol

Do you happen to have a link for that Kernal? Searched for it with no luck..

I just rooted my DInc today and I heard about a kernel that ups the battery life. Is there such a thing, and if so, can someone point me in the right direction? Thanks in advance
Most kernels try to improve battery life. Are you running a sense rom or aosp rom?
If you're talking about Savage kernel, be careful... that thing uses an SBC (super battery charging) mod that can potentially harm your device in the long run. I personally am using VirusROM 1.5.1 with its stock kernel and have seen better battery life than SBC, but that's just me.

With this kernel my battery quite literally does not go down when it's sleeping (screen off), unless I'm in an area with bad reception. Screen on is also somewhat better than stock - it's hard to improve screen on at all, since that uses the CPU pretty aggressively. However, it does use improved scaling to always try and minimize the CPU load while keeping performance up. All that + HAVS (Hybrid Adaptive Voltage Scaling, which lowers the amount of power the CPU is drawing) = win battery life

The superior battery charging kernals will not harm your device, but instead may shorten the life of your battery over time. But at 15 dollars a battery, some believe it to a negligible side effect. Its all personal preference, really.

How exactly do I go about installing the kernel? Sorry for such a n00b question, but I only did this today.

If you're sticking with the stock ROM then search for a Sense based kernel, then read the OP and associated reviews in the comments following to learn how to install it, current features (what works and what doesn't) and any other possible info you'd need.
If you're planning on installing a different ROM, those already have kernels baked in, so give that a shot first and then try other kernels if you feel the need.

I've had EXCELLENT results with the kernel from Myn's Warm TwoPointTwo RLS5 (NOT 5.2)
I forgot which one it was though... D: I think it was the ziggy 12/19...?
Kernels for Battery
I use the Newest Ziggy Kernel (BFS) with SetCPU set at conservative.
=Great Battery life !!
This kernel also enables other options like SmartASS and Performance, but conservative is a winner for battery life.
Hey all, I was wondering if anybody had any suggestions for a kernel that is good for battery life. I am running the stable release of CM7 and I have the OEM extended battery (came with the phone when I bought it) and I currently can get about 1.5 days of moderate use (wifi turned on whenever available, frequent twitter/facebook/foursquare updates, heavy texting/emailing and moderate web browsing) but I am always open to new options for improved battery life.
The kernel I have now is underclocked by about half and I find that helps a lot (if I remember correctly, it is the stock kernel).
Best kernel in my opinion for AOSP is Tiamat: http://tiamat-aosp.com
I am somewhat new to the non-stock rom/kernel game but have the latest version of incredikernel with CM7 stable and really like the combo so far
The stock CM7 kernel had lower wifi performance for me with Incredikernel it is back where it should be

Agreed. Incredikernel FTW.
Flash the lower voltages to get even better battery life. If your phone can take them without rebooting often then you'll get a significant increase in battery life while maintaining the same CPU power.
2.6.37.6-incredikernel is working phenomenally for me
Incredikernel is the best I've found on any aosp rom. Awesome battery life.

Curious, is there a guide or instructions on how to flash the lower voltages. I've checked out Chad's thread and it confuses me.

I went with Incredikernel. So far so good, it's been off the charger for about 13-14 hours now and it's at 82% battery. Wifi and GPS both turned on with a decent amount of texting/email checking and a little web browsing. It is underclocked about half way with SetCPU and still very snappy and responsive. Definitely happier with my phone than ever before.
Incredikernel is what my friend uses and he loves it.
Also wanted to add I have heard good things about Tiamat as well, another one you couldnt go wrong with.
