I cannot run a undervolted kernel on my evo for some reason, it doesn't play nice. I liked tiamat on my previous evo, was the only one I ran. while I have tiamat running i have about a minute before it reboots. My question is can I use vipermod to restore voltages to stock/stable. If so what voltage should I enable. I'm useing an extended battery 3500, if that makes a difference. Also if that's not possible what kernel do u recommended I flash to get better battery life?
Edit: trying savage 221

What ROM/kernel combo do you have? how are you flashing them? Are you making sure to pair sense kernels with sense ROMs and AOSP kernels with AOSP ROMs?
I've been sticking with stock Wich is cyan, On miui. I did some home work and it looks like salvage has stock volts by default. Lol yes I'm keeping aosp kernels on aosp roms

Sorry, it may sound like a retarded question for me to ask. But you'd be surprised at how many people are running sense and flash an AOSP kernel, or vice versa. It's always nice to get the obvious issues out of the way in order to focus on what the real cause is.
MIUI is one of the ROMs I've never really used. Make sure your battery is calibrated. That should help a bit with battery life. I'm using Savaged Zen on mine with CM7 and it works amazingly well. As far as the undervolting issue.....I am not too sure as to what is causing that.
What method do you use to calibrate. I've never done that. All I've ever done is wipe battery stats
Sent from my PC36100 using XDA App
Charge battery to 100%, enter recovery, wipe battery stats, let phone COMPLETELY discharge (till it turns off), then recharge to 100% again and use normally.
Cool thanks

As the post states I'm coming from a rooted dx. I had pretty sick battery life and I know I'm going to take a hit on the dinc.
I've tried a few roms and haven't done much with kernels. Any suggestions or tips so I can make it through the day.

Aosp roms are supposed to get better battery life and I like the invisiblek kernels I'm sure I typed that name wrong but I'm on my phone.
Sent from my Incredible using XDA App
I've tried just about every Rom out there for the incredible and I've found that the Super-Z Rom with the included Ziggy kernel is hands down the best Rom. The battery life/battery charge rate is absolutely outstanding. Additionally, the Rom itself is the fastest I've tested. With it slightly overclocked you can hit mid 1800 benchmark scores. Needless to say, this is my every day Rom and I don't see myself changing for a while. Probably not until I get a new phone actually.

I Just lou's senseless rom with this #4 kernel. a whole day with heavy use, and 2 with medium use
Warm TwoPointTwo RLS5 with the ziggy kernel that comes with it. Heavy use on the stock battery from 8:30 am until 6:30 pm and I'm at 66%
Thanks for the suggeations. Are you guys using the stock battery. I was using a few today and the battery went from 90 to 45 in just a few hours of playing around. Are there any special settings that i should stop. Ive also read about underclocking?
Sent from my DROIDX using XDA App
I'm on the stock battery. It's a stock flash of Warm RLS5, except for the transparent titlebar mod and the Warm3 boot animation. It's truly excellent.
No lie, OMGB 6 and invisiblek 28 are awesome on battery life. Only problem is some apps aren't compatible with Gingerbread yet, so if you use a lot of emulators, then you might want to go with MIUI (better than most imho).

hmm have you tried calibrating the battery? or try a different kernel? sometimes problems like these are kernel related. I know that certain kernels have drained my battery faster than others.
Nope don't use 4g, & when phone is idle it dies 10% in 8hrs of idle but after that .. man under 30 minutes it goes down another 10% or less
Sent from my PC36100 using XDA App
well honestly that's pretty normal especially for a sense rom but maybe if you try calibrating the battery and erasing battery stats, that could help you out. Also try not to have GPS on unless it's necessary. That also drains your battery. Or try a different kernel like netarchy's kernel and if it's a non-havs kernel then combine it with setcpu.
What are you using?
Sent from my PC36100 using XDA App
well I'm not on a sense rom so I'm running a savaged-zen kernel but when I WAS on a sense rom I used this one http://qap.la/~netarchy/netarchy-toastmod-4.3.2-cfs-nohavs-nosbc-noUV-universal-signed.zip
y/netarchy-toastmod-4.3.2-cfs-nohavs-nosbc-noUV-universal-signed.zip It's cfs, has no havs so I could use it with setcpu and wasn't SBC because I don't like to mess with my battery that way.

I'm on cm 6.1.2, I use the stable .0.4 savaged-zen kernel without SBC and with Wimax. and I average about 20-22 hours every day with moderate-heavy usage.
Why not use cm7 wimax?
Sent from my PC36100 using XDA App
If it's charging too fast and dropping to fast, I would guess you need to calibrate it.

For some reason I just prefer cm 6.1.2 but I'm fine with waiting for the stable cm7 to come out. I use a kernel with Wimax because all of the savaged-zen kernels are Wimax capable.
Honestly though, try calibrating the battery and then either use the kernel you have now or a different one but always remember to wipe cache/dalvik-cache
I'm about to flash cm7 wimax, and what can I have my brightness set to?
Sent from my PC36100 using XDA App
you can use auto brightness. I usually keep it on the lowest because I find the others to be too bright for me personally and when I'm in bright places I set it to auto. By the way if you use the savaged-zen kernels, set the wifi sleep policy to never to avoid random reboots.
I recently flashed to cyano 7 RC. Ever since its seemed to me my battery life has been lower than with stock. This is contrary to the Roms reputation so I'm curious if anyone else has had a similar experience.
I'm using the stock kernel mostly because I don't feel familiar enough with kernels to experiment yet.
Any advice would be great.
Sent from my ADR6300 using XDA App
I have been experiencing the same, although I have noticed my screen off battery is significantly improved. I've been running the nightlies for RC1 and every build the battery life can be a hit or miss with the stock kernels

chad's kernels for GB are AWSOME for battery life. remember to enter settings/cynogenmod/performance and set the cpu to smartass and the min to 128 and you should notice a huge differance.
also i like to wipe the delik cache right before flashing a new kernel. good luck

I'm interested in knowing more about Kernel changes but so far I've been unable to find any comprehensive tutorials. Many of the stickies here at XDA assume a certain level of prior knowledge.
Its as simple as flashing a mod, just download, boot into recovery or install via rom manager, wipe data/cache.
Sent from my Incredible using XDA App
Coming from someone that's been running Cyanogenmod 7 since 2-3 weeks before nightlies, and someone who doesn't charge their phone at night, I feel I have a little room to talk here. I am currently running the incredakernel by Chad. It has givin me the best balance of battery life and performance that I could possibly find (and I have tried all 2.3 compatible kernels, and some 2.2 kernels) I'm not saying he has the one and only good kernel, though it works great for me.

Smartass Govenor
128-1036 clock settings
Don't use Setcpu or anything. Smartass has a screen off built in so it gets amazing battery life. I've tried several, and found the best was not using it at all. Some say conservative gives better battery, and I can say that's false on all of my testing. One last thing. Every phone is different, and everyone's taste is too. This is not the only option, but my personal, opinion. Good luck

If something goes wrong with a kernel flash clockwork will still function right? That is to say that clockwork does not rely on the kernel at all?

Alright, I would like to know, What is a kernal. Ive flashed almost every rom possible but i havn't done anything with kernals.
Thanks

I've heard it stated as "a bridge between hardware and software." They control your processor speed for certain circumstances (screen off) and what voltage your processor gets at certain speeds. It can also come with different things like audio boost and enhanced multitouch capabilities (3+ finger input). Just remember to flash a sense kernel if you're on a sense or senseless ROM, or an aosp kernel for an aosp ROM. I always wipe dalvik cache and cache partition before installing a kernel, just to make sure theres going to be no problems.

Correct, there are some overclocked kernels and some that are stock speeds, plus all of the different tweaks that can be applied. And CM7 RC2 is a ROM. CyanogenMod (ROM name) 7 (version) RC2 (release candidate). Its a pretty popular ROM.
Sent from my Droid Incredible running CM7 RC2.
Lmao no man, im running cm7, love it to death. What is CM7, aosp ? I know its senseless.
So not to jack your thread but its highly related to the question I've been asking today. I understand the description of a kernel above but then what would be the main differences between the kernel and the Rom of a device? Are kernels simply used to modify aspects of the phone such as processor speeds or do they also have something to do with the UI?
Sent from my ADR6300 using XDA App
I dont think they have any effect on the UI
So besides just processor speed,what else could a different kernel affect?
Sent from my ADR6300 using XDA App
CM7 is AOSP.
Kernels don't affect the UI, they control processor speed mainly, but they can also come with patches that boost audio levels and enable fast charging or trickle-charge (SBC [when you charge your phone normally, it gets to 100% then stops charging regardless of being plugged in and runs off of the battery power til about 90% ish resulting in the infamous dropping 10% battery in like 5 minutes scenario. This mod enables the phone to drop its charging current once it hits 100% instead of turning off completely, maintaining the battery at 100%.]). Pretty nifty stuff

Yep, it does. I'm not too familiar with what it does, but I've heard it basically favors lower CPU speeds, saving you some extra battery life. I've yet to notice any lag or slowness from running that governor. I get pretty good battery life with this kernel too, so I figured I'd stick with it.

Would calling a phone a car chassis, a ROM the motor and a kernal the driver be a good analogy?
Which ROM is the best ROM for the Evo4G? The most famous ROMs that I always read about is Cyanogen and MIUI?
which has a better battery life?

In my experience MIUI and CM are on similar footing when it comes to battery; it could go either way since they are both pretty similar (MIUI is based off of CM).

World peace with no regard for human life.
If you like Sense, I recommend the MikG 2.45 rom. You can then experiment with the new Freedom kernels (currently at version 0.8, with varying versions (stock, less, more, aggressive) which have different degrees of undervolting built in for improved battery life.
I went ahead and tried CM7 on the EVO 4G and it works flawlessly.
I'm sure I can save more battery life if I use SetCpu profiles? Is it o.k. to use setCPU profiles with the kernel that comes with CM7? Or is there a better kernel to use?
Also, i prefer SetCPU profiles because I can use the screen-off profile to underclock and save battery when my phone is not in use.
Miui is not based off of cyanogenmod. Miui is better anyway. IMO that is.

I love sense 3.0 Roms and you should definitely try one of kings Roms and any other out there. Anyways, if you like aosp then you should def try decks. Great on battery and works flawlessly. His Rom also has the cyanogen settings to overclock and go into detail with your phone

I have to say Decks ROM is the best I've used. Its very stable and smooth as silk. Using the SavagedZen with BFS Kernel got me excellent battery life...
So far its out of Kinged kingdom or Kings Alliance. My kid sat on my phone and played gun bros for about 4 hours yesterday around midday 10ish - 2 o'clock and the battery still had a little juice left(had not been charged since like 7am). Alliance is a little better to me only cuz it has the hacked hotspot(no error 67).
The Baked Snack ROMs are renowned for battery life.
