I'm currently using Cyanogen 6.0 RC3 with the Kernel that came with it, and I'm not too impressed with the battery - seems to be draining a lot when on stand by. Just curious on the best battery-saving Kernel out there that is stable and is great with battery percentages.
Try some of wildmonks UV kernels.
I'm also wondering about this. Im currently on kmobs #48 kernel. I have set cpu with profiles set up to under clock when screen is off. Anything else I could try. And no I don't want juice defender.

x2 i've been running 2.6.35.4_SVS-950mV_CFS_AXI_720p_1113MHz_082710.zip on the latest nightlys and battery life has been very good
Just flashed the 1190mhz WildMonk's Kernel and it seems to be a little laggy, can't comment on the battery usage though (I will tomorrow).
I've been reading and people are saying >1190mhz is very stable, but I've been seeing that people are clocking it much lower than 1190mhz (at 1133mhz). I don't care about the speed, I just want my phone to last longer, and to not crash.
Should I flash the 1133 instead of the 1190?
2.6.35.4_SVS-950mV_CFS_AXI_720p_1113MHz_082710 is extremely stable on CM6 & offers much better battery life than stock kernel.
I use it with GPRS/Wifi on full time, moderate browsing (about 1 hr), 20-25 SMS's sent, 50 SMS's received & around 1 hr of talk time. Leaves me with more than 30% juice even after 24 hrs.
To do better on battery life, avoid using the live wallpapers & use a black/dark
static wallpaper.
Cheers !

Battery life on latest CM Nightlies has been very impressive with the included kernel.
i saw him tweet this... whats CM nightlies?
Pershoot is number one, no question about it.
http://droidbasement.com/db-blog/
I have brightness at 100% full-time (Love it!), I have live wall papers 100% (Love it!) of the time and have 3g always with 2 Gmail accounts push via K-9.
GPS off, BT off. WiFi off.
I have CM6.0 with this kernel (1 month old version). It is OC, UV + Extra RAM with no HD(?).
I doubled my battery life on CM6 and very easy get 1 day out of it, almost never below 30% - from 7am to 11pm. I'm at 49% (midnight) with my average use.
If I stream radio, I drain about 15% per hour on 3g. I drain about 5% to read top 20 news on Engadget app (twice a day)
This is my second kernel from this developer. I used one with 2.1 and now with 2.2. I know I'm coming again for the new one when I feel I need to.
I do not limit my usage, as I WANT to kill my battery, but can't succeed.

this is the one i have gave a try and I am very impressed.
I know this is beating a dead horse to a pulp, but I'm going to ask any way. I have never been a typical user, and I burn my phone to the ground fast. My usage fluctuates so much testing is almost impossible.
Just asking anyone who has had the patience what they have found the best results with.
I'm currently on Super Clean 0.9 and the OTB ul 1200. Flameless responses appreciated.

I have the same setup that you do and it seems that I am blowing through my battery even faster with the lower voltage, which makes no sense. I also have noticed significantly worse battery life with DJ05. Not sure if you have noticed these things as well and was the reason for the post.
Im not sure if super clean 0.9 is based off of dj05 as I use my own fragmented rom with prices of everyone elses ROMS. But the best battery life I get is out of dj05 for sure. Running a random kernel that I think adrynalyne or jt posted in irc and I usually get a full day with moderate to heavy web browsing and 3-4 hours of music. But I also have outstanding 3g in both of the places where I live so that doesn't deplete my battery like most people

With stupidfast 1.54 and superdark dj05 I feel like battery life has improved. I can go through a whole day, minimal use, and still have 82% battery life at the end of the day or hover around 40-50% with regular use.
its 9:20pm right now and I am still at 76%. With some browsing, music, phone calls.

I have seen the same with lv kernels both here and on my N1. possibly needing more pull for higher resource usage, but I'm lacking on the technical knowledge to make sense of that, and have had too much egg nog as of now.

I somehow seem to get better life from a stock with BS apps removed, but like I said, haven't tested properly. I usually hate battery life threads but have been aggravated by 9-10 hours before death as of late. Probably just excessive usage, but I'm banking on the community to share exp. with their phones.

ROFL. If I could ever put my phone down i might see better life. I like the stupidfast, but saw some minor performance delays that led me back to voodoo. Not much of an improvement on my life tho.
I have been frustrated with battery life on the sf from day one. I called VZ the other day to have the lady tell me it's normal to charge it 3 times a day due to widgets, I then proceeded to waste my breath by telling her I don't run widgets.. Her response was well they will still drain your battery.
I don't want to un root my phone just to take it in to a store and get the battery replaced and apparently calling them won't get me any where either

I use blue tooth + 3g for an hour drive to work and since the voodoo 5 kernels with the ul settings I have been at 85+% each day from the normal 75+%. So my battery life has improved greatly! Keep up the awesome work devs!

I get pretty decent battery life out of the DJ05 OTB Voodoo sv combo (around 7 hours with periods of heavy usage). I also use juicedefender but I've heard it cant control the CDMA radio properly (ie disable data and etc) but it appears to lengthen my battery life (could just be a placebo effect however)
I had the same problem....crappy battery life with DJ05 and I tried everything from wiping to endless kernel/rom combos. In the end I found out standby was killing me. Like sometimes an hour would pass without me touching my phone and it would drop 5%. Someone suggested dialing *22899 ( I think that was it) and it was instantly fixed. Now idle I drop maybe a percent every 3 hours.
What I have found is the governor does a great job of managing battery use of the CPU in conservative mode. My best combo is jt 1129 novoodoo kernel paired with black hole 2.1+ (I noticed no significant difference between 2.2 and 2.4 for battery life). My usage is fairly high, 3-8 hours of display on each day, running light apps (hardly any music, never games, synched email). Some of my numbers are posted.
Counter to intuition, I can't seem to get aggressive undervolt kernels to give me an improvement. I think it is because the minimum processor has to be kept a little higher to sustain the underlying, so on average more offline drain. This makes no sense though, because when I look at it in os monitor, the governor seems to be doing fine.
Speculating here is pretty dicey, because I have a hard time doing a lot of testing of something that doesn't seem to work. I use my phone a lot, and it is hard to justify having 40% less life span when I know of better combos.
In summary:
* I have NOTHING to say about voodoo kernels.
* negligible difference from leaving wifi and GPS and live wallpaper on.
* negligible difference between dj05 roms.
* running a custom rom gives a noticeable improvement betrays simply running ADW on to of touch wiz
* stock kernel is pretty darned good for battery life, competitive with best kernels.
* the cpu does great self management stock and mostly runs at 100 mhz for my use
* certain under volt kernels appear to under perform during non intensive tasks, but it is hard to be certain.
* bluetooth matters, only turn it on when driving or planning to talk; it does eat battery.
* leave brightness at auto or lower, pick a dark theme wherever possible. Display is the number one eater of battery. White sucks your life.
* there isn't a lot you can do to optimize battery life. Retraining the battery either works or it doesn't, but it isn't really necessary for most system or kernel changes and should be done infrequently.
* there are a few ways to eat battery fast.
* use a theme that shows battery in 1% increments, great for sanity!
* rule of thumb display on uses 4.5 times the power of display off for light apps. -- So theoretical max life on this phone is around 8.5 hours with display on, 42 hours with display off. (typical is about 4.5 hours of display on before I charge it) and yeah I should check my math... I have never had a practical test anything close to 8 hours. I would expect about 6.5 if I never locked it and kept it running in a dark app, with little data and sound use. I think a review I read got about 7.5 hours of playing avatar on loop (probably tmo galaxy s)- a result I found mystifying at the time. My personal best is about 5.5 display on.
Swyped w/ XDA App. When in doubt, jingle.
That was very informative.
I'm on Blackhole 2.4 and I tried one of the Stupidfast undervolted kernels (v1.5.4) for a week and although the battery useage improved a bit, it was somehow affecting my phones wireless reception, wifi and mobile signal. My phone usually flies thru webpages at home when it gets wifi yet it was crawling when I was on that kernel. My phone would randomly freeze as well. I just switched back to JT's 12/12 DJ05 kernel and eventhough battery useage is less desireable, I got my wireless reception back. I also just switched to a dark wallpaper, used to have an ocean / blue sky image as wallpaper. I think those beautiful/fancy weather/clock widgets affect battery useage on how often it updates itself. I switched out of beautiful widgets to gTabSimiClock widget, see if that makes a difference. I like its more simpler look.
So I upgraded my Pre for the EVO when it came out and have been using the same phone and battery since getting it. I found XDA and immediately started rooting and flashing. I started with Fresh and DC when those were about the only options. I use my phone fairly heavily as I am almost always listening to downloaded radio shows either thru a plugged in headset or a jawbone icon BT set. I would say that I averaged about 8 hours of battery life no matter what ROM and kernel combo I tried. This is everything from Fresh, DC, Virus, Warm, CM6, EViO, Evo-NonSense, MIUI, and all of the applicable kernels. The best I had gotten with all of the various combos was a little over 16 hours (with an SBC kernel), which I thought was AWESOME! Needless to say, I used Warm TwoPointTwo (including betas) for a while and touted its look, feel, performance, ease of use, and feature set alongside an SBC kernel.
I ALWAYS keep an eye on the development section for something to pique my interest and pull me away from my current setup. After trolling Lucid's thread for cm7 for a while, I took the dive when the official cm7 nightlies started rolling out. I have been with cm7 ever since. I also took advantage of savage and zendroid kernels and now savaged zen.
The longest I have gone so far is 2 days 10 hours! How? Well...conservative governor on an SBC savaged zen kernel and toggling mobile data off when not in use. Will that same setup work for you? Maybe. Unfortunately all EVO' s are not created equal.
Moral of the story? It takes alot of time, reading, and work to find the thing that works for your EVO. It was a pain to find the right combo, but it is worth all the work.
Thanks for your post. When you got the battery to last over 2 days, it looks like the phone mostly sat there, am I seeing that incorrectly?
I, like you, have tried all different things with the Evo trying to get battery and performance. I am locked on MIUI right now, it gives me the best of both worlds. If you want to try a Sense rom, try Ava's stuff. When I get "bored" with MIUI I will go back to Ava.

God will kill a kitten if you switch from MIUI. You don't want that on your conscience now, do you?
Yeah it really depends on your usage without it the 2 days 10 hours don't mean much. 2 days is no problem if I only use it to make a couple of calls. every 8 hours it only loses 4% charge when untouched with autosync on. The evo battery isn't bad it just takes tweaking like the op says
I get on average two complete days on a charge. With heavy usage I het like a day and a half, with light usage I can go 3 days. MIUI 1.1.28 w/ savage 1.6 kernel. I used to shut off my data too when I wasn't using it but with the MIUI build I'm on, I don't need to.
I really don't trust the battery use(in settings) in CM7 at ALL. I had my phone plugged into my car charger for 45mins on the way home tonight I unplugged it at 7:38pm.
It is now two hours later(10pm) it is showing I have been unplugged for10h55m9s on the posted screenshot. Then if you look at the other screenshot my battery indicator pro is showing the correct amount of time since unplugged.
I've noticed that the battery stats in cm7 do not reset unless you fully charge your phone. Otherwise it continues the count even if you plug a charger in.

MetalHead, do you overclock/undervolt? If so, would you mind sharing your settings? Lastly, have you noticed an increase in browser speeds since you flashed MIUI and tweaked your settings?
I know I need to come up with something. my battery drain is friggin' horrid.
Unplug @ 100%, turn the screen on, let it sit with nothing, pretty much, running in the background and in 10 minutes will be down to about 93%....
Tried several different combos, but all are pretty much the same results...

I overclock at 1152 with smartass governor 98% of the time. Savage 1.6 is a HAVS kernel so I guess technically it is undervolted. I honestly couldn't tell you about the browser speeds, I've been on MIUI since the beginning of November so I really have no clue what the browser speed on a Sense ROM is. Everything is a lot faster with MIUI so I'm assuming my browser speeds have also increased.

This is typical, unless you use an SBC kernel, bump charge your phone, or unplug it exactly when the light turns green.
Any non-SBC kernel will not keep the phone at 100% charge while on the charger. Some will argue that doing so is dangerous for the battery or methods like bump charging put too much wear on the battery.
This is most likely the reason that phone companies rarely have a true percentage shown on their batteries, because they all do this. If we didnt mod to get that real number shown, you would think your phone was acting just fine.
Personally, if I am really going to be using my phone a ton in one day, Ill bump charge it, but otherwise I just accept that its going to drop that first 10% really fast.
The best measure imo of battery performance is how much % you lose when the battery is somewhat discharged, and off. Every phone will drain while you use it, but most of the hours of a day, your phone is off and idle. If you lose 1% per hour, or 5% per hour, that will make a huge difference in your up time per charge.
Unfortunately, mine doesn't stop at that 10%. For instance, mine came off the charger at 5:30 AM at 100%.
By Noon, it was down to 70%, and I had 1 - 3 minute call, no texts and maybe 20 minutes of playing Klondike before work.
I guess I'm gonna have to go SBC. Worst that can happen is I end up buying a new battery, just incase it does so it in.
So in 10 minutes you drop 7%, and in the next 6 1/3 hours you drop another 23% with moderate use?
That sounds like pretty typical battery results to me, thats about 26 hours uptime with a fair amount of use. But maybe others could chime in.
Dude, 5 hands of a card game is NOT moderate use. It's practically no use. Klondike doesn't use data, GPS, etc... nothing, except minimal graphics.
The one phone call literally lasted less than 5 mins, so yes, a phone that drops 30% doing nothing is drastic.
I seem to get pretty good battery life on Myns rom.
I can go at least 24 hours with moderate usage, all on the stock kernel.
Looks like I may have found a little better stability with the Netarchy-Toast CFS 4.3.2 Havs SBC less.
30 minutes of moderate use today and it only dropped 5%
The best battery life I have gotten is from Feb 09 Plutonium.
Miks 4.5 4.2 sbc, gps on updating all every hour call, text, surf, angry birds all freaking day, and get 14 to 16hours every day
MIUI
Wow i have been wanting to try MIUI for a while and i definitely will now.
I'm getting pretty bad battery life with MIUI 2.11 on hw 003. Can anyone recommend a good kernel? I'm hesitant to try the SBC kernels based on the potential battery damage, so savaged-zen is out, also savage-zen seems to have issues with usb mounting.
Is there a link to savage 1.6 CFS, which I've read in a number of threads now is a good one. Speed is not imp, stability, bt+usb working and battery life is.
I thought I would throw this out there just because I found it quite amazing after a year of tweaking the vibrant. I just decided to swap back from Simply Honey to a 2.2x rom because I was having issues with reboots while on the phone. I had been using Bi-Winning prior to installing SH-3.9 so I went back to that but this time I installed the Bali v1.8.8UV kernel after reading some tips. I'm getting 48 hour battery life on moderate use where I was getting 18-20 before. This Bali kernel is something else. I think this setup is a keeper.
you just put on bi-winning and bali or did you undervolt as well? settings would be great cause with a 48 hour battery thats enough to get me to go back to froyo haha especially now that netflix is on froyo as well

I just put bi-winning on it, rebooted, put bali on it. I'm trying to think of anything else I did but I can't. I installed this combo friday night and I thought it was a fluke or I had forgot that I had plugged it up sometime over the weekend when I woke up monday morning with 25% battery. I made it from tuesday morning @ 7:00 until just now with 40% left. I Just plugged it up and I'm going to make an effort to actually benchmark it this time as I don't believe it either. I also just put the same combo on my wife's vibrant to see what kind of resultes it gets.
Am I subconsciously plugging my phone into the charger?
Yep, I get similar results. Currently I'm on ZenDroid 2.0.1 with Bali 1.8.8UV and I'm sitting at 35% remaining and 48 hours since unplugged. Light-moderate use I guess but with some gaming, lots of texts, several 15-20min calls, and wifi on 24/7.
ECOTOX's DragonMODz ULP kernel performs very much the same as well. I have a hard time picking between the two.

I'm currently running on Asgard 3.1.2 (Same devs, right?) and it's running awesome.
Thought I'd upgrade to Bi-Winning 3.0 on my Vibrant.

Indeed. Full Google account sync and Facebook once daily. Data is on and using KB5 modem.
Oh and I've also started using the Screen Filter app to reduce screen brightness even more than the android minimum and it seems to be helping a lot as well. Check it out.

Just wanted to add a testimonial to the OP since I'm running exactly the same thing. Just Bi-Winning and Bali 1.8.8UV, it already comes undervolted by -25 I believe and I'm getting similar results on battery life. Kernel and ROM go very well together and it's quick, responsive and very very smooth. I'm using it with ADW EX launcher by the way.
flashed both and so far so good, battery is a little better but nothing as significant as 48 hours, do I have to wait a day or 2 to let it settle in first? Cause I know when i was on cm7 they said let bali run for a day or 2 then after that youll notice the difference
No pics, no proof
Anyone of yall use GPS at all or just moderate use....
The stock battery will not last with more than 2.5 hours (+/-) of Display use, no matter how you slice it.

Well, that's just plain wrong. I've been gaming through multiple episodes of "The Good Wife" with my family and my battery is down maybe 20%.
Now, 2 1/2 hours of an all white background on maximum brightness might kill your battery (flashlight apps), but not typical use.

I don't know exactly what "gaming through multiple episodes" means but a screen is a screen. There's no software affects the display's energy use. Like I said, the +/- depends on your brightness settings and exactly what you display on your screen. I challenge you to show me battery usage screen shot with more than 2.5 hr of display on time on a single charge (with stock battery). I don't doubt you can push 48hrs on a single charge, but chances are, the display on time is less than 3 hours
Does anybody have some screenies to prove it?

Well, you're in luck! I'm breaking in a new 1700mah battery and want to drain it down to 20% anyway. I'll do so with the screen on my default homepage instead of using the flashlight app. I'll run a stopwatch app in the background and get you some numbers. If you're right, I'll eat my hat!
Then again, since you said +/-, even if it lasts 72 hours, you're still right. It's just 2.5hrs +/- 69.5 hours
I'm the OP and for the last two days my battery has not been lasting nearly as long. Of course I have gone for light/moderate use to heavy use but also I'm seeing it chew through more battery when idle. I'm not sure what has changed to make this happen. I've kept wifi off. I don't think this had anything to do with it but it seemed to start using more battery as soon as I installed the google maps update but the battery profiler doesn't say anything about maps. Oh well...
Well, after 2hr30min, my battery is at 84%. Sure, it's a new battery, and the 84% is probably a little inaccurate, but I haven't stopped the test, so we'll see where it goes from there. Wifi, Bluetooth, and Data are on as well as several widgets on my homepage. I haven't done much with it except keep the screen on indefinitely and send/receive a few texts.
Anyway, the proof is in the pudding. Mmm... pudding...
Alright, so I'm not a very heavy user on the phone but I've started getting 36 hours of use on my phone. I was blown the hell away! I usually would get a Max of up to 25 or 26 hours or so before this. Even then a full 10 hours extra is magnificent!
Here's what I've got going on:
Running MIUI 2.3.23 ROM with Bulletproof Add On pack
Using Tiamat 1.1.5 kernel
Juice Defender Plus on Advanced mode
Recaibrated my batter with Battery Callibrator app
Overclocking at 1039 MHz and underclocking at 184 mhz using SetCPU
After calibrating my battery I let the battery run out completely a couple of times and voila!
I took a screenshot of my usage statistics but I can't find the damn thing now. I guess you're just got to trust me on this. This was definitely worth sharing.
All the best!

How many hours of screen on time did you have at the end of that charge? The longest battery life i've ever had for my phone was actually 3 days and 3 hours with 5 hours of screen on time. I'm a light to moderate user and i achieved that result with CM7.2 RC1 without any tweaks.
I really like the look of MIUI but i don't find it to be as fast as it really should be. I get frustrated by the scrolling lag that is present in the settings menu and the fact that video playback is much slower in comparison to other ROMs. Web pages were also always SO much more laggy in MIUI for me than on Sense or AOSP based ROMs. That's my personal experience, i think i've just about given up on MIUI and Sense based ROMs. I haven't touched either of those for a while now.
I get 36 hours normally with the stock Sense 2.1 ROM and Unity V10 kernel. Overclocked to 1Ghz with the standard governor.
I use it quite lightly though, 10 to 20 SMS, bit of internet / Facebook and 30 mins FM radio in the morning. Also accounts sync automatically, mail picked up every hour, data always on. That was with the stock battery, with the Anker 1600 mah I get to 36 hours with about 30% to spare!
On a side note, underclocking below 245Mhz has been know to cause problems. Standby of Death (or Sleep of Death), and possibly dropped SMS etc.

*sleep of death or SOD... i think S is for sleep not standby...

i didn't mean to flame you, nor to mock you in any kind of way
thats quite insane @[email protected];;
i get about 13~15 hours of charge each time @[email protected];;
i use my phone mainly for texting and emails
no games on the phone...
i should give that a try, thats quiet insane ;o

Hehe the word you're looking for is "quite" and not "quiet(as in low sound)".

I'm not sure how much screen on time I had. I'll give it a check next time I'm monitoring my performance.
Sense UI has been a pain for me from the moment I started. I tried CM 7 but it had a bug where it wouldn't vibrate when I got a message unless it was in silent mode. Since I SMS quite a bit, it was quite annoying. I tried a couple of Virtuous ROMs too but they were glacial in their speed. Couldn't stand the lag.
I find MIUI to be the perfect balance between features, UI and speed. It might be a tad laggy in some places, but on the whole, it looks great, works great and doesn't give me problems in the parts I use the most. It doesn't seem quite as laggy with me as you seem to describe it. But anyhoo, for the first time since I bought my DZ, I feel like I have a good phone that I can rely on.
Thanks for your comments, man.

WOw! Really? Stock giving 36 hours! That's pretty sweet man. Never happened to me.
And thanks for the advice on the underclocking. Maybe I should up it a notch, just in case.

Go for it bro! And let me know if it works for you.
Right now, I've already hit 33.5 hours and have just hit 15% battery. And this is including a few games of Angry Birds. woohoo!

Letting the battery drain to shutdown is not a good idea. Not good for long term life of Li ion batteries. Also, its unlikely, but possible that draining to shutdown will render the battery unable to take a charge. Fail safes on the device and battery are supposed to prevent this in theory, but in reality they don't always work. Several reports on this device of people that drained to shutdown, and then couldn't charge their battery.
The battery meter is not accurate enough to necessitate draining to zero. Just drain to 10 or even 20%, charge to full, repeat a couple times. No value added whatsoever to draining to shutdown.
I have easily gotten 48 hours+ with light usage on various ROMs, including ILWT and Virtuous Unity (which is Sense 3, and claimed by some to be a "battery hog"). This is with Bluetooth and WiFi always on, and no special battery calibration or battery saving apps.. So many things affect battery life. But my personal hunch is that the ROM, clocking, radio, and data reception in your area (and of course usage) have more to do with battery life than other factors. And with radio and reception being the really big drivers.
That's definitely very helpful. I've always heard that rechargeable batteries are supposed to be drained completely and charged at least periodically to extend its life. Your proposition is contrary to this belief but then, I don't know that much about the battery and those aspects of the device itself to be able to refute what you're saying. Best to be on the safe side though.
Current record for my battery is 42 hours as of today. I'm pretty thrilled. My device was giving at least 10-15 hours less before I made these customisations. So I feel it probably has helped. However, there are a lot of factors at play, as you said.
Thanks for the response!

There are various types of rechargeable batteries with very different behaviors. What you mention is known as battery conditioning, where you periodically drain to (nearly) empty and charge to full, and is recommended for older type NiCd (nickel cadmium) batteries. This is to avoid "memory effect" where the battery will remember how much was discharged in past cycles, and not deliver any more than demanded before. Kind of a "use it or lose it" principle.
Lithium (Li) ion cells (the type on most smartphones) do not suffer from memory effect. And full discharge cycles actually hurt the long term life of the battery. Charging frequently is actually the best for this type of bettery. But a couple nearly full cycles are needed to properly calibrate the battery meter on the phone.
