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?

Heavy battery drain on Gingerbread

Hey Guys,
I've been trying out many roms in the last time and I've noticed that on every Gingerbread rom, the battery drain is much higher than on Froyo roms. That's weird, because I constantly hear of people's battery life getting better after switching to Gingerbread.
On Froyo, the standby consumption is at 5 mA. On Gingerbread it's 75 mA. On Froyo, I can surf the internet for 10 minutes and nothing changes, on Gingerbread the battery would lose 5%. With regular use, when the phone is full in the morning, it's almost every day empty 8 hours later.
I just want to have a Gingerbread Wildfire with decent battery life. I tried many roms, and even on CM7, battery life is horrible. Even on a clean install without any apps. What is going on there? Is it maybe the radio? Or the kernel? Do you experience similar drain?

Maybe CPU?
I dont know if this will help but Gingerbread roms often have overclock settings, have you used the overclock feature because this would most definatly reduce your battery life but otherwise im not too sure but i must say i was using Oxygen (Gingerbread) on my wildfire and the battery life was very bad compared to stock ruu roms, sorry if i didnt help :S

Any idea? Im about to upgrade to the gingerbread.

I know about that, but I don't overclocked my Wildfire. Just because the battery drain is heavy enough on regular CPU speed.

Just upgrade and see yourself, I heard about many Wildfire users with Gingerbread who got better battery performance than on Froyo. Unfortunately, I ain't one of these

After a new flash it's usual to have battery drain. After a few charges it will buff out.

underclocking ur cpu is a propable way to go. actually using conservative governor in cpu settings, may help your battery efficiency. but before doing this, search for a thread concerning this matter. u can always give it a shot and see for yourself, decide later if you want to keep gingerbread or not.

To those O/Ced a Q for you.

Im stone stock right now. Do you see an actual improvement in apps that need the extra O/C HP? I have one game I bought that seems to be a little choppy at times, 9mm HD, and Im not sure if its the games coding, the fact that it maybe having a problem with ICS, or just not enough hardware HP to be fluid.

I OC'ed when I first got the phone but quickly dropped it back to 1200. This phone doesn't need overclocking and if you are noticing lag in games it is most likely due to poor coding by the dev for either ICS or dual core phones or both. If it is lagging on a 1.2 GHz dual core and it is our hardware think about people running it on the Inc 2 with a 1 GHz single core processor and basically last years tech. Our phones should be fine to run most if not all games for about a half year or maybe a year before OCing will really be needed.

Why don't you just do it and find out? It's really hard to tell because no kernel is a stock kernel with 1.35 GHz / 1.4 GHz.
All these kernels featuring OC have additional features which means that it could be the features/tweaks that are fixing it rather than the OC itself.

Well,...Im just pretty content with how it performs in every other aspect, except for this one game bugs me a little. Ive been ROMed and O/Ced on this not too long ago, and TBH, theres always some sort of little thig that turns me off about it. A spontaneous reboot here, a F/C there, and I find myself going stock again. I would do it in a heart beat if it didnt mean having to set every last detail back up again when I unlock the phone.

And yes, being virtually OCD about this phone sucks, lol.

I have a question as well!
For those under-clocking or using UV kernels, do you see a noticeable improvement in battery life? I have a GSM sock GNex and the battery life is atrocious.

Should of unlocked the bootloader day one before playing with the phone your phone still remains stock. Just the bootloader is unlocked, you'll virtually feel no difference. Except the fact that you have to relock for warranty purposes later but you'll wipe everything so that is always good because you don't want to exchange a phone with all of your passwords.
@andythefan: Yes there is a huge battery difference. Visit the Franco Kernel thread in GSM forums for people's images of battery history.

Other kernels also have this feature. A lot of them do.

@stevessvt: In the myriad different combo's I've flashed (ARHD, Franco kernel, APex Kernel, bigxie ROM, AOKP rom, stock kernel, OC/No OC, Unvervolting, and 1 other kernel I can't even remember) I've yet to encounter a single random reboot, FC, or battery pull. I've also flashed countless different mods and basebands, etc.
It's all about doing your homework and really reading through threads before flashing and making sure different stuff is compatible and doing nandroids.
I can honestly say running a non-stock rom/kernel makes a noticeable difference in response and performance in daily use. Its really all the Kernel IMO, ROM's just give you features. I've however never noticed anything from OCing.
@andyfan: what build are you on? 4.0.2 has the hands down best battery life, and 4.0.3 with the Franco Kernel is nearly as good as 4.0.2 was (4.0.2 for me meant ~3% drain in 8 hours)

For now any phone usage will give you terrible battery life due to the high power consumption of the screen especially if when it displays white onscreen content. Average CPU usage is very low unless you're running benchmarks consistently. Therefore UV tweaks have low impact on usage battery life.
With that said if your battery is irregularly draining while idle something may be active in the background.
Franco has made many tweaks to his kernel to reduce idle power consumption. He's gotten it down to about less than 1% drain per hour which can give you over 2 days of idle battery life. Just for ****s and giggles I have achieved that with less than 30 minutes of screen time with LTE enabled.
Franco's kernel is the best I've used in terms of overall battery life but none of the OC/UV kernels have significantly increased my usage battery life.

[Q] what is the best battery saving kernel?

hey guys, i am looking for a kernel that will save me on battery. i am running zombie 4 rom. it says it runs the dark x kernel. i don't need to be running at super speeds but i don't want screen freezes either. i just want to be able to play my satellite radio without the phone draining 3 percent every 5 min or so. any help would be great.

I would be interested in this as well. Currently I am Rooted and have tried a few ROM's but haven't found one yet that doesn't have some bug or another. {Granted, I haven't tried them all} Tried one ROM that really distorted my custom made Wallpapers, which is a big deal to me. So... yes, any info on a better battery life Kernel would be welcome.
Currently I am not a "heavy user" on the phone. Talk - Text - You Tube occasionally... that's it. Constantly looking for better ways to improve this already amazing phone.

Eugenes kernel has given me great battery life. Either get down with Eugene's Macnut ROM which already has it or search for it under the general section under the bounty thread for Eugene. Its in page....58?
Keep in mind that the "beta" kernel does not have bln support but works just fine so long as you use the lionheart governor.
If you can't find the bounty thread then I'm sorry for you.

Synergy kernel has been awesome on battery for many.

How you use your phone determines the best way to get the best battery life. Basically there are two ways to save battery: cutting power when not in use and delivering less power to the processors.
If you use your phone intermittently throughout the day for texts or calls, you'll get the best battery results from kernels/ROMs/apps that cut unnecessary functions when you're not using the phone. For example, juice defender cuts your wifi and mobile data when your screen is off and reactivates it every 15min (can be configured otherwise) to check for notifications. Darkside's Digital Warfare utilizes something called "deep sleep" which actually completely turns off your processors when the screen is off, but keeps the basic cell radio on so if you receive a text/phone call it will wake up the processor. These functions have the largest and safest impact on battery life.
If you're constantly using your phone and you want better battery life, you basically only have one option: undervolting. This is essentially supplying less power to your processors, which can be done through system tuner. It's not a free ticket, however; if you undervolt too low then at higher frequencies (playing games, etc.) your processor will become unstable and your phone will randomly reboot. If you encounter this, then don't undervolt that much and up the voltage to the last safe level. Just for reference, undervolting by 50mV is usually considered safe and undervolting past 100mV usually results in boot loops. But how far you can actually undervolt depends on your individual phone hardware, there's no universal answer. Make sure to not set your undervolt settings to set at boot until you find a stable voltage. Otherwise, you'll be forced to restore a nandroid if you encounter a bootloop.
TL;DR
If your phone already lasts a day and you want it to last 2-3 days, look into ROMs/kernels/apps that cut unnecessary functions when not in use. Most effective way to extend battery.
If your phone lasts 8 hours and you want it to last a day because you're a heavy user, look into undervolting with system tuner.

Why do I get horrible battery life with ROMS and Kernels?

I've used cm9 and aokp the past month and tried the stock Kernels that come with it and Franco's. One thing is for certain. No matter combination I get horrible battery life. If I run stock android with my extended battery including various Widgets I get 24 hours battery life pretty easily. Moderate usage and some heavy usage. With cm9 I'm getting maybe 15-16 hrs with aokp maybe 8-9 hers and I'm using Franco's kernel right now. I don't understand this. People talk about how much better the battery life is with various ROMS than stock but I'm not getting it. I'm getting like half the battery life I was before. Any ideas?

I can relate to you. Was in CM9 and Franko's kernel and as you said, horrible battery life. I went back to stock but this time I did not install apps thar would require services running (well I have to run WhatsApp so that's the only one running besides default abdroid services).
I am seeing better battery life this way.
The next step would be to install CM9 and restore all my apps to see if I can replicate the same battery life.

you need to find out what apps are keeping your phone from sleeping dude its not the ROM or Kernel if you want to find out you can use better battery stats or just read the permissions on your apps otherwise its probably cause your on your phone too much with the screen on first show use a usage screen shot then how many apps you have we can narrow it down

Well, this has pretty much nothing to do with the ROMs/kernels, you flash to the device. If you use the device for heavy gaming, you use loads of apps etc. the battery life will obviously be bad, because the CPU needs the according CPU clock speed...
Underclock the CPU, or better: Get AnTuTu CPU Master pro, and set the profiles, underclock screen off, to 700 MHz, and every other proile, where you do not neccessarily need the device to that speed, not below, otherwise it will just crash... That way you have the best battery life, for your usage, so basically, every time you switch the device's screen off, it will save a hell of a load of battery

Under clocking doesn't do much for battery life contrary to popular belief. It just increases the time it takes to process a task. It might take 1s at 1.2ghz vs 1.8s at 800ghz to complete a given task for example. So yes the cpu will run at lower speed and voltage but it still also take longer to return to idle.

Well, I don't really mean to break this, because it is right, but not completely...
Underclocking & undervolting, when the device is not in use (Screen off) saves loads of battery...
And because it's a dual-core, it takes mostly just as long to open an app at 700 MHz, as when you're doing it at stock clock speed, or voltage or higher.. So, in that case...

Not sure how this wouldn't have to do with the different ROMS and kernels since I stated what battery life I was getting with stock vs using a custom kernel and ROMS. I'm giving a comparison of my battery on each with the same usasge and they are different.
