I'm currently running Fresh Rom (newest) with the stock kernel that it comes with. My battery life is not near as good as it was before I rooted.
Question is.....I'm running setCPU currently and have been thinking about flashing to Netarchy to see if my battery life increases. Does anyone have experience with this combination's battery life compared to running stock with setCPU? I'm not sure setCPU will work with the Netarchy kernel or not. Also, is Netarchy compatible with wireless tether and 4G?
Thanks.
I run stock with SetCPU and love it.
if the kernal you are using uses HAVS, SetCPU will be no good for you.
goodandevo.com has some nice tips for saving some juice also...
20-tips-to-improve-htc-evo-4g-battery-life
that's pretty much all i can help you with... sorry.
I had no luck with batt life on Fresh 3.3...I ran all of Kingz kernels and then NA's...no luck. If you want good batt life I suggest a new rom...Myn
Good to know...I had TwoPointTwo on with Kings #11 not long ago but took off because I like the interface on Fresh a lot more. Something tells me Sprint TV app was disabled on this by default as well.
Are you running Myns currently? Which kernel did you like the best with it for battery life?
@SpaceMonky.....
I believe the kernel that comes with Fresh does not use HAVS...so SetCPU should be working fine.
Also, I have done all the things listed on goodandevo.net as well as numerous other "tricks". Only one I have not tried is the Colin hack made for Evo by Myn. Still up in the air on whether this actually makes a difference.

i have been running flipz newer rom with the new unreleased kernal and my battery life is AMAZING, I mean very very good. I was thinking about giving CM6 a try again with flashing the new v7.6 kernal thats supposed to be really good.
But I was wondering what people are getting with cm6 and the kernals as far as batt life.
Ive never personally flashed a kernal before so not sure on how well or how much they affect the phone or if its worth it.
any help? like as far as the best kernal for a CM6 rom and and reports on batt life comapred to the new leaked kernal
I'm getting better battery life on stock now, then I was on any other modded kernel (kings, cm6, and some others.)
Nand backup and give it a shot. It seems way to better to me than stock or even cm6 nightly with newest kernel.
also whats the difference between bfs and cfs roms?
i feel batt life with CM6nightly + snap7.6 in turbo mode is about how the phone was when it was first released...you can make it a day with light use, but using it a ton, i seem to get around 8-10 hours.
However...getting 2600+ in Quadrant and no lag, anywhere, ever...makes up for it. I'm always within reach of a USB port or wall outlet so i just carry the charger/cord around with me.
I haven't actually ran it from full to dead outside of work. However at work i constantly drop signal and regain it repeatedly for the 8~ hours i'm here.
ok well im running the stock rom and JT_Rom beta 2.0 and im testing out other
ROMs such as calkulins evio 2 and others.
but is kingxkernel bfs 4? the best?
i need something really good. overclock?
i want to have the best battery life.
how can i do this?
yes
i would likke to know the sam ething
I am running CM6 and would like to use the best battery saving kernel!!
I am having great results with King's #11 CFS
Really good battery life? I'm just starting to use kings CFS #9.
Sent From My HTC EVO
King's #11 CFS has been running fantastic for me. I am using the Azarel v2.3 ROM with it. Strangely enough, the first time I loaded Kings with Azarel, the phone was super laggy. I gave it a reboot or two and now it rocks. I have never had good battery life, even with stock 3.29 or other ROMs and kernels. I could make it throughout the day with moderate use and have about 15% left. I have been unplugged today for six hours and have 80% left with slightly less than moderate use... Slow day.
I'm also on radio 2.15.00.09.01 and PRI 1.34 on a HW rev. 003 EVO. The 1.77 PRI dropped my signal strength here in Ocala, FL.
Of course, make sure you wipe your cache/dalvik before you flash the new kernel.
Hope this helps!
Yeah,i did so. How long til the battery life shows progress. This is the first kernel I'm testing. Kings cfs#9. How can I calibrate the battery ? I wiped the battery stats to make it better to .

Perf Test
Since battery life seems to be the biggest gripe, It would be nice to have some type of non-biased performance test / graphs for some of the ROMS and kernels.
The Common misconceptions and other useful information... post at the top of this sub-forum has great information, including manners to calibrate your battery.
The problem with testing ROMs and kernels is that everyone's phone is slightly different. Some can't over/underclock to the same degree as others' phones. Sometimes a particular kernel will cause your EVO to force close applications or have other strange problems such as rebooting.
If you search the forums, you will see that there was one person in particular that did a graph of performance testing with various ROMs and kernels.
My advice would be, if you are confident enough, to go ahead and test each of the "leading" ROMs and kernels and see which one works best for you. You can also refer to the Wiki which has ROM/kernel information available.
I wanna know how if it works best for you. I wouldn't know what to test.

Flash ROM.Flash kernel. Use a few days. Note battery life. Repeat.
Those are definitely the best steps. Personally the new 3.3 ROMs kernel is supposed to be awesome for battery. I like the Azarel and myn ROMs and have had good luck with Kings #11 and netarchy's kernels. Your mileage WILL vary which is why you should do your own testing.

So just rooted my Dinc and trying out some roms. The most important thing for me is battery life and then stability. I wanted to know some if your ROM/kernel combos that have given the longest battery life. Thanks.
Each phone n processor are different in stability so basically youre better off finding out for yourself...personally been using redemptive rom with ziggys kernel and love it.
Sent from my ADR6300 using XDA App
I've had my best life with Virtuous (been with it since early 2.0) and I've used King's BFS kernels. Now I'm running Ziggy's BFS and lasting even longer.
And to what the guy above me said, each phone is different in the sense that only some can overclock to 1.19 while others can't (I for example can't). Other than that, each phone is pretty much the same.
It seems like the stock Cyanogen ROM and kernel has better battery life than Virtuous with King's BFS #5. I just don't see how King's BFS #5 is that good.
I'm going to try the stock Virtuous kernel later in a somewhat controlled environment to see if there's a major battery difference.
Hey all,
I just flashed Sprint Lover's ROM and I was wondering what is the best Kernal for this Sense ROM? I really like the stock look, but I would love to improve some performance under the hood.
Any help would be great!
Thank you very much!!!

I always use Netarchy's kernel, but what may be good on one phone may also be bad on another phone. I suggest flashing different kernels and testing them out.

Go Here for his kernels. I use Netarchy Toastmod - 4.3-cfs-havs-more-sbc and so far it's worked amazing on the various ROMs I've used (including Sprint Lovers) but it's worked best for me on Myn's ROMs.

I think I'm gonna flash this kernel tomorrow, but maybe the nosbc so I don't fry my battery... Have you had any issues with the battery with the sbc? And do you use SetCpu with the kernel?

No, and no
Don't use SetCPU with a havs kernel. If you go with one of his nohavs kernels then by all means use SetCPU as you wish. Another thing, just from my personal experience (though it may be different for your phone) the CFS kernels work far better than the BFS kernels. There's a guide around here that explains the difference.
As far as SBC goes, I haven't had any issues yet. I've been using a battery monitor to watch what's going on with my battery and haven't seen anything wrong with it. Another thing I do, just as a small precaution, is not let the phone charge 6-8 hours over-night. I'll let it charge to 100% then let it sit for about 2-3 more hours and call it quits. Don't know if that really does anything, but it makes me feel better so eh.
I know the military (I'm in the Army) uses Lit-ion batteries and trickle charges them without having any of them blow up/fry, however they do lose their ability to hold a charge over time. The fact that they do it, and the only problem has been lifespan of the battery is what convinced me to try an SBC kernel. Just choose whichever you feel comfortable with. It's all preference really.

I've been using that one with no-sbc and it's worked great with the conservative profile. HAVS just deals with what voltage the processor uses at any given time/frequency so you can indeed use setcpu with it. It's the kernels with the built in smartass governor or ROMs using other battery tweaking scripts that don't always work well with setcpu.
And trust me, the military does not trickle charge their li-ions and they only run them at 4.10 volts to extend their life (depending on battery, always less than volts than their commercial counterparts). This I know for certain.
Anyone have a link to the stock kernel
Sent from my PC36100 using XDA App
Guys quick question, with the above mentioned kernel. What frequency does if use when you turn off the screen? I want if to use the lowest possible, does the kernel do it automatically or should I use something like the overlook widget?
Also, can someone please provide instructions how to update the kernel, I haven't looked at the link yet so If there's instructions there that fine.
Thanks
wifi errors
i just flashed to netarchy kernel to my evo. cfs, havs no sbc. when i try to connect to wifi it says error. i used kernal manager to flash the kernal. is there anything i can to do to get the wifi back or do i need to go back to the stock kernel. i am running sprint lovers ROM. any suggestions.
update. when i flashed manually everything worked fine. maybe the kernel manager program has an issue with wiping the cache. not really sure. just thought i should let everyone know.
I would use the stock #15 HTC Kernel but with SBC. Link is in sec post here..

I've been using netarchy 4.3.4 cfs more havs aggressive sbc with no problems. Amazing battery life and very responsive.
Netarchy's kernels are very stable,if you're up for it try a sbc kernel,great battery life.
sbc
i was just reluctant to try an sbc because of the horror stories i have heard about frying the battery. i guess when i feel lucky i will try it.
I would like to find a good overclockable kernal and am not really having luck finding much info about them. I see SVC and all that stuff but i dont know what all that means. I am running the newest version of IncRom and love it besides it having a stock kernal. I use alot of wifi teather and am on my phone alot so i need something thats going to be a strong signal for the wifi and i need one that charges fast and has acceptable battery life. I know i cant have everything all in one but i have flashed like 6 different roms and notice the kernals do matter for example the OMFGB 1.1.1 rom the battery dies so fast i can watch it drain but takes 5 hrs to charge back up. I have no use for something like that u know. But on the flip side it has an overclockable kernal!!! So could someone guide me in the right direction or at least break down what kind of kernal im looking for??? I really would like this info thank u.
I have CM7 on my phone but replaced the CM7 kernel with the latest version of incredikernel. It has been good so far and I have great battery life. I can set the governor to overclock my CPU up to 1113 MHz and I have verified the increase in speed is giving more performance through a couple of benchmark apps. I am also able to do either wifi or USB tethering without any issues as the CM7 rom has native support for both of them. You may want to try flashing your baseband radio as the different versions will offer different performance. I am using 2,15,00.11.19 right now and it is working well for me.
incredikernel AOSP is excellent for both battery life and overclocking. I can't speak for the Sense ROM, but I'm sure it's just as nice. I can say that the AOSP roms charge QUICK, and with the smartass governer, you can oc and uc and have great battery life.
I'm running chad's incredikernel right now on SkyRaider 4.0 and I love it. The smartass governor is great for battery life and it charges really fast. It's the only kernel I'd run on a sense ROM
