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 have enjoyed using kernels from geeknik, jt and Adrynalyne and have been using them since I picked up my Fascinate since September. I have been using this phone along with juice defender and juice plotter as well, an it has had a great impact on battery life. One thing I noticed back on Di01 was that the standby on this phone was phenomenal. There have been time where I have only lost 3% over 12 hours with the combination of juice defender. However, since I have upgraded to DJ05 and DL09, it would have the same standby for 3 or four hours then precipitously drop 10-15% on standby in around a half an hour. I notice this on juice plotter. I was wondering if anyone else has noticed this, and if it may be something with this rom or a particular kernel. I am running Adryn's 12/30 kernel and I have tried jt's kernels and stupidfast when it was being used as well. I also used Adryn's 12/16 and 12/17 voodoo kernels with no difference. Any takers? I am also apologizing for this being posted in development. Was jumping on tabs between development and general and put this in the wrong section. It's kind of late.
Try a cache wipe and wipe the battery stats too in cwm the kernels themselves are fine and the undervolting will give you better battery life than not
Has to be your phone or battery.
I'm dj05 voodoo with juice defender, on standby for over 3 hours I well lose at most 1%
Newb question. What is considered standby? Hitting the power button thus turning the screen off and locking it?

I have done the battery wipe, but not with the cache. I don't think it's the battery because it was working great before. Had two fascinates with shot batteries and I know the difference haha. I'll try the combo of cache and stats wipe. I thought it was strange too because there should have been nothing short of the screen on full blast and a demanding game that could make the battery draw down like that. I'll give it a few days and see what happens. Thanks for the replies.
You and me both brother. But I don't use juice defender. I'm actually resorting to turning off data to save battery once school is back in session.
I hear ya. What I love about juice defender is that it keeps the data off most of the day and pings the network for data for one minute every 15 or whenever you want it to. I was doing great on it before. I recommend it pretty highly... unless it is actually the culprit for my battery drain haha. I was using doubletwist, but noticed in the logs it was using 45% of my battery some days without me even using the app. Keep a lookout for that everyone. Not an app you'd expect to be doing that.
I am having the same battery issues. I don't think it started after my bump to DJ05. It was definitely the worst when I ran StupidFast 12.20, after rolling back to StupidFast 1.56, it improved a lot. Still not as good as it was in the before time, in the long, long ago.
I did wipe my batt stats, but not my cache, so please let me know if that makes a difference. Battery life is everything.
Well, I'm DJ05 and voodoo, and have had a terrible battery life ever since I upgraded. I just installed juice defender and ultimate juice this morning, and in about 3 hours, I've lost about 12 percent battery... that's with moderate usage, so I'll keep this going and see whether it actually lasts to the end of the day.
Update:
Well, it seems to have actually helped a decent amount... while my phone was idling for about 5 hours, I lost about 5 percent battery. But, under heavy usage later tonight, it went down a lot faster. So, for anyone having these problems, these two programs seem to help, at least while idling.
Experiencing the same issues. Yesterday I went from 76% to 38% in 5 hours with moderate use. Before DJ05 I used to be able to get atleast 15 hours of moderate use on a full charge. Now I get about 10 if I'm lucky. I've tried various kernels. I used to run geekniks on DI01 with no problems. Thought it was voodoo, but since have removed it and am running geekniks 1.54. Not sure what's going on. I'm wondering if it is because I am using the stock DJ05 w/ certain apps removed......
jv
edit: Since unplugging from car charger not even an hour ago, I've lost 11%! I've used my phone just to do about 10 minute Google chat and gotten about 5 emails. I'm almost tempted to go back to DI01......
edit: Unplugged at 10:30 from car charger and now at 31%! this truly sucks. I won't be able to last a day with the phone like this. May have to go back to DI01 and put up with the GPS.....
I have noticed the same since I went to DJ05, what I am running is in my signature, I noticed the other day I was watching a movie with 54% batter left and 1hr and 30mins later I was down to 15% batter power left... is watching a movie that demanding? My screen res is as low as can go on the stock adjuster,
Well I unplugged at 6:30 and I am 75% and it is 3:25. Not that bad, but from 7:30 to 10 I went from 93% to 80% all on stand by. Then 8 went from 80 to to 75 from 10 to 3:25 also on standby. Makes no sense really. It seems to just have random times where the phone just eats battery on standby for no reason. It does tempt me to downgrade and yes, this is not official for a reason. I wish there was something that could be done about it. I don't want to give up my Gps

this is the only reason why I wouldn't downgrade. Also, with my luck, as soon as I do downgrade Froyo/Gingerbread is going to come out and then I'll have to do this whole data wipe thing again !!!!

I thought I was going crazy. Good to know others are having this issue. Saved me from wiping my phone and trying another ROM. Hopefully someone more knowledgeable can chime in and find the culprit.

My phone was down to 9% at 8:30 with pretty light usage. I'm hoping that there is something in the new DL05 build that will help with this. DL05, for me, has been having lightning quick gps lock ons. As quick a my og droid was actually. I just can't give that up though. I have been tracking this for a while, so I was curious to see if others had the same issue. Glad to see that I was able to bring this to people's attention.
My battery sucks as well no matter what I try with DJ05 or DL09.
I'm even running Voodoo5 125mv under-volted

I had absolutely terrible battery using the Stupidfast kernels after 1.54. It seems like most posting about poor battery life are using one of his kernels. I switched to Adrynalynes 12/30 and have MUCH better battery life. Maybe 2% per hour loss on standby and went about 30 hours with moderate use. I suggest you guys try this kernel or JT's.
Edit: Just FWIW anytime you use the GPS the battery is going to be raped. I think I used about 30% in less than an hour while geocaching. I was really shocked.
I am seeing the same thing as KenKeno. The stupidfast kernels sucked my phone dry so I gave up on them back in december. I'm using JT's 12/30 and went 35 hours with light to moderate usage. I don't use juice defender or anything like that either.
One other thing I noticed about the stupidfast kernals was that they tend to slow down the longer you go with out a reboot. Jt's kernals don't feel like they do this. So, maybe just give jt's kernals or adrynalynes (just an undervolted version of jt's kernal) a shot, they feel just as snapy to me. boot times maybe a little longer but that doesn't really matter does it?
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 am running CM7 on a D2 and i am experiencing pretty short battery life. I went from Liberty 2.0 rom on froyo last week, and upgraded to GB and flashed CM7.
I have barely used it much today for example. Took it off the charger at 6:30am have done nothing more than sent a few texts and browsed a website for about 10 mins. It is 10:30 and i am already at 70%
I did a proper battery stat reset this past weekend also.

CM7 GB Battery Issues
I am having this problem as well. Ever since I rooted and installed Rev's CM7 GB build a few days ago battery life has been much worse. I tried installing Jake's Mods V13 but if it is helping it is not helping alot. Yesterday, made 2 short phone calls, sent 3-4 texts, browsed web for maybe 10 minutes total, and was on tweetdeck for maybe 15 minutes. By end of the day was down to 30% battery. Pre-root and CMY probably would have been about 60% - 70%. Here are the battery stats when plugged it in at bed time last night:
15h 16m 23s on battery
Cell Standby 55%
Phone Idle 19%
Display 13%
Voice Calls 9%
Android OS 2%
TweetDeck 2%
Has anyone figured out a solution to this? Really liking CM7 but I am afraid to play a game or something on the phone because I'm afraid I will run out of juice!
CM7 does have a shorter battery life than stock and some other ROMs. It's still the best ROM and it will eventually be back to better battery life. I use SetCPU and JuiceDefender.
Should I go into the CPU settings on my phone to find ways to increase my battery life? If so, which setting should I alter?
I have been using the 1Ghz/undervolt option in Jakebitesmod along with Juice Defender and it seems to be helping. Battery will usually last me all day with moderate use.
You might want to try SBFing back and starting from scratch. I was on Liquid 3.0 and has atrocious battery life due to the 'Idle' process and was seeing 10-15% battery life drop each hour when there was absolutely no use.
I switched to CM7 and things were much happier. Maybe 10% loss after 4 hours idle. FB app did drain the battery once but I think I backed out of it while it was loading so it was trying to load GPS or something but outside of that no battery life problems what so ever.
Have a EVO now with Sprint Lovers ROM on it. kinda cool I suppose. However here is my big thing. I use my phone mostly for email / some texting and a boat load of talking. SOmetimes I will be on a conference bridge for 2+ hours straight. problem is I seriously have to have a charger handy all the time. Cuz I can pull off my phone from the charger after charging all night and loose 1-4% battery life right away. Not sure what thats all about.
I just last night did a battery calibration and installed setcpu (paid version). and this seems to have helped some. but not where I'd really like to see it.
I know with using on a average-high day 500+ minutes during that day. it's not going to last me all day. thats fine. but having to plug it in before lunch time to recharge it, seems a little to much for me.
I am open to any and all suggestions on what/how to fix this. new ROM, software hacks etc... or both.
Software I run:
Flex dialer (paid ver)
built in email client (checks 2 different account every 15-30 minutes, which i know is a battery drain)
text (average light use)
CSIPSimple (sometimes)
web browser ( once in a while)
Thanks for the help!
Try an aosp rom like CM7 or Miui they get better battery life than a sense rom.
Best battery life I've ever gotten was with the Deck rom 1.2.1 and the savage zen BFS SBC kernel version 2.2.1. If you couple that with an extended battery you could go for days without charging.
With a year old stock battery and that setup I had pulled 20-36 hours (I know its a broad range, but 20 hours was the low) depending on usage.

When your battery reaches 100%, your phone stops charging and lets the battery drop down to 90% before it will kick in again.
any AOSP such as CM, Decks, omfgb, miui.us, ect. coupled with tiamat or savagezen SBC kernel you will be free of charging worries & smiling.

Swagged Out Stock, Lithids Freedom kernel universal, either more or aggressive. Pretty good battery.
