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?

I ran that same combo for a while and IMO the battery did what it does best: SUUUUUUUUCK%$#^& ! .......that been said it's been like that pretty much all the time, if you really use the phone that is, not complaining at all, just saying. That's why I always carry a spare one. There are way too many variables and setup preferences that might differ from one user to the next and if you overclock the thing uses even more juice. Really love the 3.3 Rom but the lack of 3G deal in my case forced me to reflash in a different direction........Good Luck !

What do you mean by lack of 3G ?

Exactly that......no 3G, very very poor signal if any, I thought it was just me but after reviewing the ongoing 3.3 thread I found out that some people are experiencing this issue too, very small % though. In my case I was with T-Mobile for quite a while, fantastic service but poor signal-coverage at my business location so I switched to Verizon which really rocks signal-coverage-wise until now......sooooo......I really love the ROM and really hope for a feasible fix to get back to it.

it has to be a downed tower or old prl the rom/kernel dont control the phone calls so id say to check with vzw and run the appropriate updates, hope it gets fixed for ya

I'm using KK BFS #5 and the latest SkyRaider and I've got no such issues. No 3G troubles, no battery suckage, no weird stability issues...
Seems all ok for me. I'm happy with the combination. Sedio 1750 battery, BTW.
I do have SetCPU installed, interactive governor, and a profile to lower the clock speed to 612MHz when the screen is off. When awake, the phone is overclocked one notch to 1036MHz.

Not too sure where you heard this from. Could you post a link? I've used nothing but KingXKernel's on various Sense-based ROM's, and I've used SetCPU to tweak each and every one of them.

I've been running KK#5-BFS on SR 3.3, and my battery life (stock battery) has been pretty fantastic. Of course, that's completely relative, and I'm not a super heavy user, but with all other variables being constant, my battery life has definitely improved since going with this combo. You just have to be intelligent with your SetCPU settings, profiles, and phone settings.

I initially had the same 3G issues with SR 3.3, but ihtfp69 has since fixed these problems with 3.3.1, and my 3G has been flawless ever since.

I use king kernel BFS #5 with setcpu and i get some pretty amazing battery life

I am running the same combo with ROM and kernal minus the SetCpu and forget to charge my phone overnight. So for over 24hrs I was at 29% battery life. This is the best combo I've experienced so far for great battery life. Make sure you do a full system wipe, once you Flash the ROM..

does anyone find that charge times have increased after installing king's kernel 5? It may be just my imagination but I wanted to see if anyone has seen the same

Rom and kernel help!!!

I'm in a dilemma! For the last week I've been hunting around to find the right combination of Kernels and Roms. Natively I'm a CM ASOP man. But I've tried everything from CM to MIUI to Ava to Mym. None of the roms are giving a decent amount of battery life. I've tried several combinations of Kernels also. My battery life has been as terrible as 3 hours. I'm talking about losing a percent every minute!
I didn't buy an extended battery. But I have tried a brand new regular battery to make sure that I didn't have a bad battery. Both batteries have the same results under all combinations of Kernels and Roms.
I've seen members braggin on having 12 to 18th hours of life under heavy use! How is that possible!? Lol! I know it has to do with device, kernel, rom combinations.
Can the awsome members of the GREAT Xda please help me out? Point me in the right direction. fyi: I have a ver 003 device and also I don't overclock much at all but I underclock to try and save a lil juice!
Thanks in advanced!

No matter what rom/kernel combination I run I get really ****ty battery life with the stock red HTC battery. For me personally investing the $70 or so for the Seidio extended battery on Amazon was worthwhile. I also purchased their wall charger as well.
I'm not going to blow smoke up your ass and say that the battery last 2 days with heavy use because thats BS. However, with heavy use (running emulators, gmail sync, occasional bluetooth for wii mote, texting, web browsing, etc) I can get through a 9 hour work day with a lil life to spare.

At least go on amazon and get a1800 mah battery. They are cheap but goood.

I just bought another stock battery and a wall charger, I keep the spare in my wallet and battery life is a non issue now.
Check out batteryboss.org before buying an aftermarket one though, most of them are rips offs.

I'm not sure about rip offs on amazon but certainly ebay..i bought two batteries w/a charger for $25..and a third one since my oem battery took a bath, fully charged.

You should see if you can get a replacement battery from sprint. I am using CM7 nightly 24, and can easily sustain 24+ hours with the OEM red battery.
Everyone will have different results even with the same rom/kernel, however the drain that your experiencing does sound like your battery might be going bad.

I see your stats and that sh*t is wicked! I used CM7 and that one drains the quickest lol.... before I cash out on a new extended battery where's an abundant source of Kernels? I've tried three and I wanted to do a little process of elimination before I pull out my visa lol

There aren't very many CM7 kernel's available yet, so few that I can't even begin to tell you where to start looking, for Sense roms though, search for Netarchy those kernels work really well.

I see... I appreciate that! Imma give Mym a try with a few of them Kernels. Thanks again for the help
And what exactly is the Kernel that you are using!? Lol
Sent from my PC36100 using Tapatalk

Honestly, I've found that the right kernel makes the biggest difference and setcpu, juicedefender, etc only make it worse. For me (also 003 hw) kings kernel and htc # 15 uv have been best. I've had great success with azrael and vaelpak roms. Currently on vaelpak with kings # 11 with NO battery saving apps. I get 24 hours with my regular use. Yesterday was very light, I went 24 hours with just under 50% left.

This is what I've been testing for a while. This build contains auto bump charging based on the voltage as opposed to the full charge method. I don't know how it works on extended batteries yet...but works pretty good on stock batteries. With this, you should have a better chance of picking up the phone at higher voltages.

I know you guys said that setcpu can make matters worse. Is it alright if I use it to underclock to 245x245 when the screen is off and if the battery ever goes over 110°F automatically? That's the only profiles i use to help with battery maintenance

You had to say that I'll have a battery saving kernel for the gpe with a tweaked governer setup in a day or two to try out. The goal being to not lose power, right? Well, we'll see!
Shortly after, If I get it right, Bob will probably put it in the v500 if there are no conflicts. I'm going for 20-25% savings. Eh.

Typically my screen will consume about 93% of the battery.
Will a rom or kernel be able to save 20~25% on the screen consumption, or only 20~25% of the remaining 7% ?

Cool! The changes are slight, but should be very effective. I didn't want to lose any power.
Let me know how it works!

Okay, here's the scoop.
I have used 5 hours of screen on time with 43% of my battery left!
This was a mixture of Facebook, kindle, and dolphin. The screen is using 90%, at about 55% brightness average.
Given these variables, I figure to get at least 7.5 hours out of a charge.
Here's the even better news. The 88sleektweaks has made my tablet response BETTER than without, and can easily tweak this toward more battery in the future. Without a doubt.
I can see getting 9 hours out of this with no feeling of slowing down before I am through. Yeah, that good!
I have to stop where I am now though in order to test another kernel.
Anyway, that is a two hour improvement over what I was getting,... With better/faster response from my tablet.

Is it not required to go through a few charging cycles before battery stats start being accurate?

I can't say yet as I encountered issues with android system and android os using up battery. As I installed your tweaks as well as starting using greenify at the same time I made the (wrong I think now) choice of removing your tweaks.
But it now looks like greenify (or at least my going nuts and hibernating every thing ) is the problem.
So for now I've reset greenify and will monitor it overnight.
Once I'm happy with that I'll reintroduce your script

I doubt it uses much if anything. Sometimes when I haven't used the tablet all I have to knock 4 times instead of 2. LG's stock roms are better than samsung's stock roms. You could always try one of the aosp roms as a test comparison. My tablet was idle with LG's stock rom and bob's kernel for 1 day and 14 hours and I only lost 5% battery life no radios (bt/wifi/gps) were left on.

How enable init.d in stock 4.4.2 ?

Click to expand...

You would need to build a kernel for stock 4.4.2 that has init.d support. You would start with the LG kernel source, get the source to build and then try to incorporate Sleekmason's changes that he has done for the GPE device into the V500 kernel. This would involve carefully looking at his tweaks and applying what is needed for the governor and init.d support into the stock kernel. Once you have built a kernel like this and it is ready to install. Then you need to root your device and you would need to install a custom recovery so you can flash the new kernel. The installation instructions would be different from what Sleekmason does since the GPE device has an unlocked boot loader.
When I was trying to do a custom kernel on 4.2.2 I found that my resulting kernel from LG source didn't match the installed kernel on my device. This bothered me and I wanted to make sure I understood the differences before proceeding. This combined with real life getting in the way (my wife is expecting) caused me to shelve the project.
I believe I finally figured out what I was doing wrong. However I'm now running 4.4.2 so my efforts are not useful to me other than to help me if I decided to attempt a 4.4.2 kernel.
