Fresh Toast vs. ffolkes' Kernel

So, there you have it. Aside from stability, my main concern is conserving battery life. In fact, I'd sacrifice the 30FPS unlock to conserve 3+ hours of battery life if need be.
Which is better for stability and battery life in your opinion.
Also, please post what ROM you are currently using.
Thanks!
PS - Let me know if you'd like a new poll option added. (Nevermind, apparently can't tweak that now.)

Haven't tried ffolkes yet I can say I got 22 hours out of fresh 26 with underclock while screens off

I have used DC, Baked Snack, and fresh. I think fresh is the most stable of the three. DC with JIT enabled causes reboots at times, but they are rare. DC with JIT disabled is pretty stable. Baked Snack sometimes gave me odd problems, but it is pretty fast.
I think I had best battery life with DC, about 35 hours. My brother reportedly used his phone for two days straight playing games without having to charge it. He uses DC with DCConfig set to Battery Saver. This was with an undervolted kernel without using overclock. Had to switch from undervolted at a later point because it caused HUGE amounts of stability issues. (Ffolkes' kernel)
Fresh with autostarts is pretty good with battery life. I haven't tried the latest version. Using a perflock disabled kernel and setCPU works wonders for fresh and battery life.
Baked Snack was an odd one. My battery life was inconsistent. All I can say with that one.

My thoughts on the three ROM's that Jykinturah mentioned are the same. Using DC 3.2.3 with ffolkes using set cpu, I charge my phone about as often as my girlfriend who has a blackberrry: every 2 days.

ffolkes' Higher Frame Rate Kernel
is this the 5.2 ?

in the ffolkes thread there is a link to an app called EvoSwitch. It allows you to change a value called T2 (it has something to do with frequency I guess) which for some people (including me, with an 002 bought on evo release day) actually allows the fps to change.

Thanks,man! I will try this over the weekend. I had tried some of ffolkes kerenels previously with no success. This might do the trick.

so which kernel is supposed to have the best batterly life?
I just put on fresh toast. I get a good 49fps
So far so good. to early to tell about battery life tho
Thats what im looking for

Best kernel for latest fresh?

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?

[Q] [MikFroyo] how have you extended battery life?

Hey guys, im using MikFroyo 4.4, stock kernel, no app killer. Im getting about 15 hours of what most would consider light-moderate use.
Im wondering what i can do to extend this without losing features. Is anyone getting better battery life and if so how?
custom kernel? overclock/underclock? other tweaks?
Thanks.

I use an SBC kernel (SBC #15 v7 from MS79723). There's rumors that it causes battery meltdowns, but from my experience I find that highly unlikely. I've been unplugged for 11 hours and I'm at 60% with what most consider moderate usage (about 100-150 texts, some light web browsing, a phone call or two, a few levels of angry birds). I'm also using Slayer's Cyan Dragon theme which looks badass but I'm not sure what it does for battery life (lessens it, makes it better, i dunno). The set up seems to be working pretty well after a couple of days of the kernel reading accurate battery stats.
I also reboot every morning when I wake up before I unplug to close any programs I still had running from the prior evening. Hope that helps.

Cool, anyone else using the same? different? Thanks guys

I too have been using SBC kernels for a while now with no problems and excellent battery life. Im also running a rom based on Mik's. Im using the 131 sbc kernel and i could not be happier. I also run setcpu for a screen off profile.

There are many different ways to conserve battery do a search. I believe HTC admits we should only get like 6 hours use. Try different kernals and see what works best, but give each one a couple charging cycles before deciding. The setup im using is great but peoples phones react differently.

Thanks for the input guys. I have been searching but i wanted some direct input.
Do you guys use app killers/memory managers too?I was using auto memory manager, but decided it was having little or no benefit at the cost of occassionally having to reload the UI.
Also what does SBC stand for?
Thanks everyone

I do not use anything but set cpu. Do a search for sbc theres a thread that gives all the explanation of different kernal terminology but im not sure exactly where it is

Ok cool, yea i looked it up last night and figured out what things like SBC and Havs are.
So what kind of battery life are you guys getting?
What kernel are u using with setcpu? you cant use that with stock kernel right?

You can, you just can't overclock on the stock kernel.

Kernel:
Netarchy 4.3.1 cfs-havs-sbc
Set CPU:
Screen off - 245 min 576 max
Screen on - 998 max 245 min (conservative)
Juice Defender:
Data turns off when screens off, reneables after unlock only. Enables every hour for 3 minutes to check email and such.
Task Manager: Quick system info task killer widget (only when I need to free memory for a heavy game)
Been listening to radio.com app over Bluetooth headphones while connected to wifi for 3.5 hours. Down to 76% from full charge.
Normal daily use for me is 200 texts, 50 or so emails, hour of calls, 2 hours of web, and at least 30 minutes of games. I take the phone off the charger at 7:30am and I can go till midnight no problem.
Friday I did a reboot at 10:50 am from a full charge and at midnight I was at 62% with a little lighter usage than listed above.

Thanks, sounds like the two most used kernels are netarchy and SBC. Any other good ones?

Ive ran the 4.4 and 4.5 betas now 4.5 final. Ive also run myms and cm7 Mikfroyo is by far the best in my opinion, but I like sense

I like sense but I have no loyalty to sense, aosp, or any other...I just want the important stuff (speed, battery life, working features, stability)

Welcome to the scene. Sorry for the smartass comment, literally just read the sprint echo announcement and had some anger to get out. Try mikfroyo with either launcher pro or adw ex for serious speed and smoothness. I prefer launcher pro for the sense like widgets without the sense like lag.

Tiamat or Savaged for AOSP?

Which one are you using, and why? I can't figure out which one to load. I know I can try them out, but I was just wondering what others thought on the subject.
I'm running CM7 right now, the official release.

I am running Tiamat with the CM7 Final. My battery life has been much better than before, usually get about 18 hours of use. Everything seems to run nicely! I did a lot of research and tried a bunch of different ROMs, this one has been the best for me.

Tiamat!!!!

I get awful battery life with SavegedZen. Everything is smooth with Tiamat, and I get great battery life. Ironically, I feel my 3G/4G and tethering speeds are faster with the Tiamat kernel as well.

I was using Tiamat when I was running CM. I was getting really good battery life and leaving data, wifi, gps ect... on. I usually charge at bed time and average moderate use but never had an issue with low battery.
In fairness to this post I have NOT used SZ so I might be biased. I have been reading up on it and noticed on cyanogens forums a lot of people swearing by the combo so I will probably give it a ****. I think this far into the game either are superb choices and it boils down to personal experience and phone specific issues.

I use Tiatmat 3.3.5 scb kernel and love it. I took my phone off the charger about 11pm last night. I played on it for almost 2 hours solid and went to sleep and left it off the charger. I got up and spent about 30 minutes on it this morning. So far it has been up 9 hours and 44 minutes and still have 52%.
I selected a SBC kernel because I read on a thread over on XDA that it's best to use them if not charging all the time and you only charge overnight. Lot's of speculation on these kernels killing the batteries from what I read but I have yet to see any confirmed reports that this kernel damaged the phone.
Cyanogenmod & Tiatmat for the win!

Tiamat for battery, but savage has it beat on performance. Depends on what you want.

Mine is slightly reversed from everyone else in this thread.
Tiamat gives better performance but SavagedZen gives better battery life for me. I even discussed this with Tiamat's dev, cayniarb. I guess my Evo is weird.

Need best battery rom. NEED TO KNOW BY 9a.m.

Right. So a friend of my friend made me root his phone a while back and I threw mikg 2.52 on it and all was good. Now the guy contacted me today and said his battery life was in the crapper and wants me to change it to something more battery life favored since he isn't by a charger for a long time throughout the day. And since I have been using the new ics roms and jumping back and forth often I don't really know what to give him now.
So what's your opinions? I need something stable as a rock and best battery possible. I need this to last him a while since I almost never see this guy... Haha
P.s. I know people hate these kind of post. Just bear with me here because I'm meeting this guy tomorrow morning and have to know what I should flash for him. Also no aosp please.

You could have him try the one in your sig. It gave me great battery life when I used it, but as always, YMMV. You really have to try them out and see which gives the best battery life for you.
Also could try apps like Juice Defender or similar that aim to optimize battery life.

The only rom i can think of that ive used that doesnt drain your battery would be cm7 or decks gb. Ive used it myself & ive seen good battery life even with my cpu overclocked.

Does it work on viper rom? V2 redline? Thanks! Please let me know

I have the latest MIUI by Swiper, and since 2.2.6, my battery life has been phenomenal with Tiamat kernel 4.1.0, Car-O-Dope tweaks and Vipermod -50.
Phenomenal as in comes off the charger at 6AM and when I get home from work at 5, it's still over 80%

I can confirm this.. ALthough I use 2.3.2 b1 and 3.3.7 sbc kernel as I had some reboot issues with 4.1.0 but yeah.. I'm still at 100 percent at 11:00 am (work at 8).. come home and still at 90. go to bed and hit the charger right above 80. It's unreal.. I consider myself a heavy user too... email,sms,phone calls... etc.

I am currently using Swiper's 2.3.2 b1 with 3.3.7 sbc and have not run into any issues. Battery life is great with this combination for me. Also, keep in mind that I do not run many widgets except an calendar agenda widget.

Myn's Warm series rom's always gave me the best battery life.

i use energy sense 3.5 rom with anthrax kernel. iv had decent battery life w it. about 14 hours or so w moderate use and in and out of roam looking for signal. from what iv read CM7 and MIUI roms are much better with battery life than sense roms. they also seem to be more customizable.

80% at night with heavy use throughout the entire day? I can't believe that. Screenshot? If someone else can validate this, I might try the rom with LEE kernel.

He did mention no AOSP (although AOSP really does have the best battery life IMHO)
Koni's Elite Series III combined with netarchy-toastmod HAVS-less had decent battery life, only issue is that was a Froyo build.
kluster1999: I agree, pic would be awesome.

I don't mean to sound rude, but different ROM and kernel combinations can only make so much of a difference. I'm skeptical of claims of amazing battery life with heavy usage because in the end, the battery is still the same size and the large screen still draws a lot of power.

Been having great Battery life with "The Exress" using" Lionfish more" kernnal and smurfed out....
