CM6 is definitely great, I think without question it is a vast improvement.
The only issue I have is my battery life is ABSOLUTELY HORRIBLE. Could be the worst battery life I've had with any phone. But maybe that's just the EVO, with it's big screen and speedy processor. I underclock to 384 mhz sometimes but then the thing slows down and even freezes. I have 3 different batteries and they all perform about the same (not good.) Before I had a partial wake issue but that's gone, and battery life still stinks. I've also tried calibrating but nothing really seems to make it better.
I hear the snap thing is good for battery life but I everytime I open that thread I get a headache. I love this phone and am obsessed wtih it but that thread is a bit much even for me!
Can anyone give me a quick and dirty explaination of what snap is / how to use snap? Which kernel to flash? Some day I hope to digest that mammoth of a thread, but right now I'm too busy reading texts for college and Just want better battery life.
Thanks!
Download app System Panel. Will help show you what is eating up your battery/resources.
Then, download app Juice Defender. Worth it to get the paid version. Its like 3 bucks IIRC. This will help you get more battery life out of your phone.

Yeah, I tried System Panel but the things eating my battery were mostly system things, like Browser. I guess I could give it another go.
Why are Juice Defender reviews so bad? I've considered it before also, maybe will try playing with it again
snap 8.2 is the current release. you can try any of the kernels, but i would avoid the 7.0/7.1 SD Card implementations since that technology has been put on the back burner for a bit.
Snap allows you to you Overclock and Undervolt (aka: UV).
Overclocking of course is for speed and Undervolting may save battery.
all EVOs are not created equal. some like undervolting some do not. so snap is available in multiple flavors. each with a different UV floor. the lower the floor the more potential battery saving..but also the more chance for a random reboot or wifi/gps acting funny. remember UV retards the amount of power so things can act goofy. the different UV floors are 800mv - 925mv. for example...i use the 8.2_900 because it works well with my EVO. the 8.2_800 booted great but after a while started rebooting itself. 8.2_850 just hung at bootup. the 8.1 kernels didn't work for me at all. 7.3b1 was great.
HAVs is adaptive..so don't get stressed if your device fails to boot properly the first time. wipe the cache/dalvik and try again.
so download a few of the 8.2 kernels.
make your nandroid
begin trial and error (I'd suggest starting at 800, 850 then 900 to get a feel)
don't be afraid to wipe the Cache and Dalvik multiple times.
don't worry about the whole thread. just grab the last few pages and read the OP. then feel free to ask.
i also recommend setCPU. you can find some threads for SetCPU configurations to help. BUT....make sure SetCPU is disabled when flashing the new kernel. once you get a working kernel you can enable SetCPU...but during testing phase it will give you gray hair.

Just a few quick thoughts on voltages/freqs after seeing a handful of discussion in the thread:
1) Every 8.2 kernel has voltages lower than stock. The default stock voltage @ 245 is something around 1050.
2) No real effort is made to UV at the top end. It's a little lower, but the objective at the highest CPU frequency is not to UV. Most of the benefit of UV comes at the low end of the scale when your phone is idle (most of the time). Less voltage = less draw.
3) nHAVS scales voltage at each step. There is a min.max voltage at every cpu frequency. This range is fairly small--50-75mv, but it enables HAVS to decide based on feedback from the CPU which one to apply. And the max at each step is lower than stock. So no matter how you slice it, even if you're running 925, you are undervolted. This becomes a question of how undervolted.
4) OC is not about undervolting, it's about overclocking. The differences is voltage vs. frequency. OC means we're increasing the CPU frequency beyond stock which is 998mhz in the case of Evo. If you move your SetCPU slider beyond 998mhz, you're overclocking.
The objective of overclocking is speed. The objective of undervolting is battery savings. Snap gives you both. We overclock when we increase the fequency with SetCPU. We undervolt automatically via nHAVS. As of this writing, UV is handled in the kernel, it happens most at the bottom end of the frequency scale.
I hope this helps clear up some of the questions. Great conversation by the way.

GREAT EXPLANATION Dragin!!!
and also, to the OP.... dont forget, if you do go with setcpu, do NOT 'set on boot' mmmmkay??? lol
Thank you Dragin!!!
That helps a lot! So once you have Snap setup at what you feel is "good" does your phone seem to perform as well as before you had it undervolted? Man, sounds like a pretty involved process - maybe I better wait until I can really sit down and play with it.

Do you mean for the first flash? Or every time you boot your phone?
If not set on boot, it means you have to start SetCPU manually after each boot. Doesn't seem right

Regarding Juice:
I didn't really read too much into the reviews for this particular app. It works. I was having battery issues. Downloaded Juice, got the settings somewhat right to my liking and so far no complaints. Unplugged my phone from charger this morning at roughly 9am, been using it moderately all day, and as of right now at 12:50am, I am at 29%.
Bad reviews or not, I can attest to it working and making a difference in battery life.

Do you know what in particular Juice is doing to give you better battery life? like what does Turn off certain things based on conditions or?
That is some good battery life.
Correct.
You can set conditions to do certain things. Such as disable data/3g/wifi while screen is off. Also if you need data synced you can set a condition to enable data wifi or 3g for X minutes every X minutes/hours.
I am not affiliated with the dev in anyway but it def made a difference and was worth the price for it.

Meh... see I really don't want to do those things. I can turn off data sync myself and just have gmail forward me a text message when I have an email. I just was hoping there was a way to get decent battery life without going back to the days of Winmo
I absolutely adore CM6, but I'm really starting to think that it is not battery friendly. Last night my battery went from full to 25% in 8 hours. I had nothing running, my partial wake was fine, and Android system took up 60%+. I really don't feel like doing another wipe, but it looks like I may have to. Just want it to work right at this point.
Again, I truly love CM6, the open source concept, the transparency, the whole clean idea of it, but there is something seriously wrong with the battery life (at least in every install I have tried)

i agree with you. but i also feel that CM6 is on par with the Official HTC/Sprint ROM when it comes to battery life expectancy. however, after i put on the snap kernel and copied someones setcpu config....i got 26+hrs of 'use it as i wish' time + still had about an hour of in-pocket time left. i was hooked. i bet you an imaginary dollar the same will happen for you.
as for finding your EVOs kernel made in heaven...
it's not too bad so long as you have some time. but if you are time strapped, need your phone in 20min and don't read the OP... you will curse and swear. expect to get hung up at the HTC splashscreen a few times and it will bootloop on you before your done. <I'd suggest just leaving your battery cover off until you are done muckn about for that session>
klick may be easier for the some end users because of fewer selections. I've never used his kernels. if i try them, i'll prolly wait till he's put out a few AOSP versions...to work out any bugs.
oh yeah...one odd thing, it seems that sometimes folks flash a incompatible kernel it gets 'stuck'. after that 'bad flash' they are unable to flash any kernel until after they have nandroided back and rebooted...then they can flash again. i had this happen twice....i was unable to get a known good kernel to load until after i restored from backup. /shrug
oh....try this. download the snap7.5_925 kernel. if it runs smooth. call it a day and you should be pretty happy with that until the new versions come out. yeah, if you got one of the _800 kernels running you may pull an extra 30-45min of time...but that requires a level of geekdom that not everyone has.

Yeah dragin, don't hog those sweet settings! I'm enjoying Snap 7.6 and it seems to be helping out my battery life a bit, but I'd love to see your SetCPU details.
I've found that the issue for me is bluetooth. If I have it on constantly my battery will drain 10-15% per hour. With bluetooth off it's only draining 1%-2% per hour.
Seems like the bluetooth needs work on CM6 in order to have the efficiency that the other ROMs i've tried (Fresh and EViO) have. Nonetheless, I'm sticking with CM6 and just use the bluetooth when necessary.
I have the same issue with bluetooth on CM 6.0.0. I am running the stock kernel that comes with cyanogenmod, so this is definitely not a snap issue. There was a bug submitted about a month ago:
code.google.com/p/cyanogenmod/issues/detail?id=2136
I *really* hope this can get fixed for the 6.1 release, but it is currently listed with a low priority. I really love CM6, but basically making bluetooth unusable for more than a few hours really makes me struggle with the using this rom.
Why not the 7.6 with turbo...just wonderin
Can anyone tell me which ROM (STABLE) provides the best battery life on HTC EVO???
Thanks!
I have been through just about all on this site and Fresh's newest seems to work best for me. With moderate daily usage I can go without charging for about 22-24 hours. Of course all I need to go is 12-14 b/c I charge every night anyway, but I did leave off charger one day just to see how far I could go. I'm giving Calk's latest a try right now to see how it goes. Just be sure to give whatever ROM you try a couple charges before making a final decision, as it usually takes this amount to get an accurate read on true battery life.

I know that the latest kernels off the latest build have been killing my battery, it's horrible for my EVO.
But you really have to try different rom/kernel/PRI/radio combinations to find the best battery life for your Evo. I wish there was a preset rating system for each rom though, just to see how things work for everyone else(i.e. battery life, quadrant scores, force close problems, etc.)...but there really are a lot of variables, so I don't think that may ever happen.
Yeah I agree there isn't a clear cut winner. Everyone uses their phone different so it will differ for everyone.
Totally agree to give it a few full charges... I suggest when you get a new rom and/or kernel installed to reset the battery stats (can be done in recovery) then use it till it dies then charge to full before turning it back on.
Personally, I've been using Fresh 3.3 w/ the Kings #6 kernel and not only has the phone been screamin' fast the battery has been good. I'm only on my 2nd charge up though so I still have one or two to go before everything smooths out.

I think it would be a great idea for this kind of stuff to happen. Some aggregated source where everyone can submit their information using various roms, kernels, etc. Whether it be information regarding Quadrant scores, linpacks or battery life. On computer hardware forums they generally have a section dedicated to OCing records with charts listing someones entire setup while attaining the clock speeds. I don't see why a similar implementation can not be done here.

i use Fresh's Rom made my battery life live avg abt 15 hours
Over 40 kernels were tested and benchmarked in 7 different ways, and the results are posted here.
Should tell you everything you want to know, without bringing roms into the picture (since battery life is most affected by the kernel used, not the rom)
edit - looks like I'm a bit late withthat link - I see the thread for that site was already posted above. It's a great resource.
Fresh 3.2, hands down best battery life for me. 3.3 was pretty bad, as was myn's release....which sucks, because myn's rom is otherwise awesome.
I am using Fresh 3.3.0.1 with a baked kernel that is able to over clock. I then have SetCPU installed with profiles for different states of the phone. If my screen is off I have the cpu set to a max of 500MHz to save battery if there are any processes running in the background. I then have my cpu set to 1119MHz when the phone is plugged in or at 100% with the screen on just because I like a snappy phone. Then when the battery drops below 50% I have it return to stock speeds.
I use my phone heavily for things like subsonic, QIK, FB, Calendar, wireless tether, and of course since unlimited data, calling to any cell, and texting I am on it a lot keeping in touch with friends. I also use the sprint nav at least twice a week.
Results will vary from user to user but so far the phone has been on 7 hours and after some moderate use it's only down to around 75% on the battery.
Again this is how I MYSELF use my phone with this rom and kernel this may not be how you use your phone and you may see different results.
What I have done is searched roms and installed them in total I have used 4 different roms. Baked, Cyanogen, Fresh, and Virus. After installing each rom and setting up my phone I made a nand backup of each so I can flash between them as needed to test. I have found out of all of these roms Fresh 3.3.0.1 with a kernel from the baked roms has worked the best for MY daily use.
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.

I have to say I have tried EVERY ROM on the SGH-T989 and can say none are as stable and have the battery life to match the stock ROM.
I tried Darkside today. It is a clean ROM. Close to stock. I had two complete lockups on the phone that required battery removal in about a 6 hour period. I am not overclocking at all. The ROM has an underclock by default.
I just think it's time to give Samsung and the programmers there a thumbs up for doing such a great job on this phone.
It would be nice if they could release more of the header and source so the developers here could have a better chance of getting a stable ROM built...but until that happens I will just stay with a rooted and stock ROM.
Peace.
I've had no lockups or any problems in the 150 hour uptime I had with Juggernaut 5.0 with 009m faux's kernel.
Battery life is much better as well. Dropping down to 80% after 1 hour of display time.
Cool story bro

I was on the stock ROM for 6 hours yesterday. Surfing, playing games, wifi enabled. Used a bit over 30% from a full charge.
I jumped right into custom ROM's when I got this phone. After going back to stock is when I realized how much the custom ROM's actually degrade the phone.
I have ran Jugg's 4.x with Faux kernel and Bullet kernels. Bullet was faster by a good bit. Battery sucker from hell though.
Do these phones really need the overclocks and tweaks? After going back to stock my opinion is no.
Peace.
You probably didnt follow the directions when installing any of the roms you tried.
If companies like samsung were as awesome as you say they are, would XDA exist at all in the 1st place?

If companies like samsung were as awesome as you say they are, would XDA exist at all in the 1st place?
Enjoy your bloatware.

Keep it civil and to the point. Don't attack my character by implying that I don't know how to follow directions and flash a ROM. I have been a member on XDA since the first year....much longer than you.
I don't have a problem with bloatware. I use a stock ROOTED ROM and remove the bloatware. Very easy to test and then delete bloatware using Titanium Backup.
XDA got it's start back when the CPU and chipsets on phones were very slow. Over time the new phones have become handheld computers. The processing speed is much faster.
In the beginning the OS's were in the infantile stages as well. They have all improved dramatically.
I remember when a flash on something like the HTC Tytan made a huge difference. You were getting the GPS and FM Radio Unlocked. The bloatware was removed in the ROM(Windows based...no ROOT access). It made a huge difference in the performance of the phone and unlocked a lot of features.
This isn't the case with the new phones. There really is nothing being added to the ROM's that can't be added via the market or removed using Titanium Backup.
What I have seen with every ROM is intermittent lockups that require battery removal and excessive battery consumption probably from the aggressive timings that aren't necessary.
Peace.

I look forward to your battery testing!
Please include multiple kernels as you test various ROMs, especially faux and Synergy
And perhaps install Juice Defender as a best case.
Personally I haven't experienced any lockups with the two custom T989 ROMs I've tested, but have benefited from the improved battery life dramatically. I'd still love to see a more controlled experiment, however.

Read it. It is basically a generic thread. No stats or true testing methods just some user comments.
I want to actually test the phone in real life conditions. Watch some vids, talk on the phone, skype/gtalk/YM video call...etc. Actually run consecutive tests across the best ROMS and stock and see how they match up.
Benchmarking is a bit ridiculous....in several aspects.
If a game runs 30 fps or greater...you won't see the difference.
If a game runs a stable 30 fps versus a ROM that peaks at 50 but valleys at 15....you will definitely see the difference.
If a ROM runs 50 fps versus 30 and both are stable...you won't see the difference. The question then is which one uses less battery. The obvious answer is the one running 30fps. Less frames means less redraws and less CPU and GPU.
I just want to once an for all be able to definitively say what each ROM is really doing to the phone with graphs.
Not hard to do. Just takes a real world test model and some time. I think I can test one ROM a day. I will test the most popular ROM's....Juggs, Beast, Darkside, Bombardier, Gingersnap, etc... I have tested them all. I know which ones are legit and which ones aren't.
Peace

Agree 100%
Nothing has performed better than stock 2.3.6, rooted and debloated.

I run Juggernaut 5, ADW launcher, AOSP ICS themed, with Darkside's latest kernel (extracted it from Darkside ROM pakage), and I've had amazing battery life, OC'd to 1.83ghz with ondemand governor.
And IMO Touchwiz is ugly, samsung tries too hard to make all their stuff look like the iPhone. They do a crappy job of it and it ends up being a dissapointment.
I think any small degradation of battery life is worth the noticable boost in snappiness and cosmetics of the phone. I personally couldn't stand the stock phone, as soon as I could I flashed something different.

Strictly aesthetics can be achieved through the use of different launchers/lockscreens. The point of ROMs/Kernels need to be more than aesthetics. Hence, "some" of the ROMs offered [strictly speaking] are a pretty big disappointment because they're nothing more than themed stuff baked in and offer no real functionality.
I'm REALLY interested in a controlled experiment of battery claims of different ROMs/kernels. Preferably all at stock speeds.

Sorry but there is absolutely NO proof in these pictures.
I can see that your phone was on battery for a bit over 1 day.
I can also see that 45% of your phones battery usage was the display...and that the display was on for a bit over 7 hours.
What I don't know is what was your screen brightness set at?
Does the display percentage represent JUST the LED power for the screen or does it also include the GPU/CPU driving the display?
Where are the numbers for the stock ROM?
Those numbers mean nothing when you don't have a standardized test bed and procedure.
Peace.

You can use a home launcher on the stock debloated ROM and get the same results with more stability and better battery life.
I recommend you check DXHOME out to see a smooth launcher.

Actually, unless that test was completely skewed (e.g. screen on displaying black screen), 7 hours of screen on time + 20 odd hours of standby time with use of radios/connectivity is very very impressive.

I agree with your first paragraph 100% and will get the experiment underway with Stock speeds.

When you can refer us to pictures of a base ROM with the same parameters and settings for comparison then I might say it is impressive. But with no base ROM data it is purely speculation.
Peace.
enjoy the drm laden ciq enabled features... That cannot be removed by titanium unless it can magically decompile recompile frameworks on the fly...
Enjoy the Memeroy leaked jobsmanager....
Anyways now thats oout of the way
How much time did you spend between stock firmwares and custom firmwares?
Did you fully wipe the device before flashing and after
Did you do dirty nanoid restores?
A little more info woud be helpfull
at the end of the day if you enjoy stock more great for you.... Use it n move on...
Still missing the point of this thread on a dev website unless you like being trolled.
Guys am almost flashing 1 or 2 roms daily, till date i experinced with 7 r 8 roms..but none of them satisfied me...some ROM had problem with the basic things like camera, camcoder and other things, some other ROMs lack in battery usage...
So can someone sheds some light on this part...
As long as you're on a new stable ROM such as ICS you're battery should be fine. JB is too early to know really but it's fantastic for me. So, assuming you're now on a stable ROM (a non Sense ROM would be better too) the problem is either your battery or you. I would recommend getting a new battery if you still have the 2 year old one the phone came with, and tbh I'd recommend getting a new Ankers 1600 mAh anyway as they're fantastic, lasts me days.
Now that you're on stable ROM and have a shiny new battery, if you're battery life is still bad then the latter problem I mentioned applies, that is, you, or rather how you are using the phone.
If, like many other Vision users I see around the forums, you are overclocked to absurd speeds well over 1GHz running the performance governor then have I got news for you of course your battery life is going to be terrible. For this reason, tbh you really don't need to go over stock clock speed and if you use the Virtuous OC daemon then you can under clock significantly when the screen is off, this saves enormous amounts of battery life.
Also if you are using the phone constantly and have the screen very bright, data on all the time etc., then you've got to accept that you simply won't last more than a day between charges.
By the way I'm not going to recommend a specific ROM because as you should know "what ROM should I get" threads are not allowed, I just wanted to give you some general battery help.
Hope this helps

Am using this ROM : [Flinny] Andromadus Test builds - CM10.1[17]
and my phone is just 40 days old... so the battery will be fine abvsly... then i wont over clock it more than 850 mhz, so it satays under stock freq. then i will be using the mobile in half brightness,, i used to hear songs nd play games lil bit... even though my battery last for jus 12-15 hrs... thats y i doubt on the ROM, but am not sure ...
