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.

Wow, I'd love to have that kind of time with CM6, right now I drain at about 10% an hour with no usage at all; where can I find that setcpu config? I really like CM6 but battery life is killing me right now.

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
Configuring this thing for good battery life is exhausting. Before root I had done most things listed in this thread : http://www.xda-developers.com/android/tweaks-for-superb-battery-life-in-evo/ and finally achieved pretty good battery life.
After root, I have never been able to achieve this even though the bloatware isnt running, have various tweaks on there for performance, and so on.
Have tried Fresh Rom with stock and Kings #11 and liked it but had terrible battery life. Tried Myn's 2.2 with stock, Kings #11, and Netarchy and battery was not much better. Now running AVA9 (no flashed kernel) and battery is no better. Have tried running setCPU on all these setups and does not help.
Any suggestions? Seems someone will say this rom/kernel combo works for them and another person will say it sucks, don't use it.
I couldn't stick with Myn's because there were too many bugs/errors. If my best bet is to go back to all HTC stock rom w/root then so be it.
.....and yes, I have read through the numerous amount of threads on this topic but no clear combination has been highlighted that I have seen. I use my phone for business primarily so it needs to last me as long as possible. The thought of increasing my phone size with an extended battery is not appealing to me.
I have stock rooted 3.29. I initially did the plug-unplug trick when I got the phone. Then, I turned off always on data, and set email, google accounts, and Sense weather widget to update once an hour. Phone behaves the same as when data is always on, so I don't even notice 3G off when the screen is off.
I get 8 - 10 hours under very heavy use (constant fiddling, email, games, internet, calls, etc),
10 - 15 hours moderate (surfing, ebooks, email, internet),
and easily 18+ with light use (email, occasional light surfing, occasional call)
I have everything the same as before root so with the bloatware and some other things not running would think it would last longer than stock......not!
@greyopaque...what was the reasoning for using stock rom instead of custom? Battery life or just never tried any of the others? Would like to know if your battery life is better with just the stock over others.
Ditto....I am a heavy user and leave everything running that I need. I use the phone for what it was made for. After trying/not trying all different types of roms/battery tweaks/advanced task killers/battery monitors etc., I decided to buy another original red 1500 battery as I don't like the extended battery look either. So, until they come with better battery technology....I guess that would be the career to go into and make some money ;0).....we are stuck with the best phone ever...yet....with a battery life that sucks for those of us that put the phone to the test....have a great day!
Yep...only problem is having to shut the phone off, change battery, then power back on. All the while, missing whatever phone calls come in.
***My point of the thread really isn't the terrible stock battery but the fact that the pre-rooted setup lasted so much longer than the rooted w/custom rom. Why??
I would think the battery life would get better without all the bloatware and other worthless services running all the time.
Once again.. you need to check your apps. Most likely there's something causing a drain.. Try updating to the newest rooted stock roms (3.30). The new kernel is definitely an improvement.
As an aside.. what bugs did you have with myn's 2.2 rls2? I ran it, and it was fine. Now on rls3 beta and amazing rom with great battery (3.30 base).
To be honest, I've never tried anything else. I really like the stock Sense experience... and since this is a work phone, I need it to work without glitches.

Well....hopefully I can hear from some peeps that have used a good amount of custom roms/kernels, as well as the stock one and see what they think.
Cmon guys....let me know!
@eyeballer1......Myn's was just acting weird and I kept getting a "com.htc.bgp" force close that I couldn't fix. Also, I have tried the newest stock rom but it is just so darn plain jane didn't keep it on long enough to test it. As for apps, I have basically the same apps on my phone that I had before root (except for specific root apps such as rom manager, titanium, etc).

Sadly they won't.. That is battery technology.. This world is pretty much stuck where its at and will probably stay there.. Its the one thing that is not progressing that much.. Even from the 50's
That said.. the thicker battery is the way to go.. Only you will know its thicker, and trust me.. ITS NOT THAT BAD! Believe it or not you get used to it.. If its for business, well then a thicker battery should not bother you at all, use it during the day and maybe at night switch back to the smaller one.. You know, for the dates and ****
The thicker battery will be a life savior.. All these battery tricks and tips help, but nothing is going to be mind blowing.. The fact is, this phone is extremely advanced and requires a lot of power.. I just except the fact that I need to be close to a power charger at most times..
I might go ahead and try Myn's new beta with 3.30 and see what happens. Looks as though I need to look deep into what is actually using my battery. I have always used K-9 for email and have heard it sucks up battery, but it only uses about 2% on mine and is the best email app I have ever found.
@fastfed......I'll have to ask my wife if I can go on a date sometime.
what helped me the most was wiping battery stats correctly (as per cyanogen wiki, but applies to all roms).
Charge to full, turn off, wipe battery stats. Turn back on, wait till everythings loaded, unplug. Use as normal until battery dies (do not charge at all until battery dies). Recharge fully in one go (meaning do not unplug while charging until full). Use and charge as normal.
This should be done whenever flashing new rom.

The biggest positive jump I have seen in regards to battery life was going from Cm6 to 3.29 ruu stock, then I ur3 to root.
I'm still sceptical that the 3.30 zip update gave any improvement to battery life as I have seen others report. In fact, I almost wonder if I somehow have less battery life now, but it could be in my head. It's almost impossible to approach this issue scientifically since I use this evo all day.

I'm gettin great battery life using vaelpak 2.3 with the stock htc kernel. I imagine most of the custom kernels around are based off of older kernels and while they may have higher "performance" ratings though I have hardly been able to tell a difference between kings 11 or baked speed and battery, I think the newer stock kernel is your best choice no set cpu to worry about, its just simple. I'm personally gettin about 14 hours with almost constant music playing to bluetooth headset, a bunch of browsing, and occasional use of google navigation which is a big battery eater. With just phone and text use after 21 hours I was at 52% yesterday.
ok so i have literally flashed every major rom / kernel and a comination of each. I have found that with minor tweaking most sense based roms get close to the same battery life. some people will argue that this or that rom is best but I would challenge others to truely preform a test on them and i bet they would be suprised.
k-9 is only a battery hog if you have it constantly polling for new emails if you have it set up to scan constantly then it will take a reasonable about of battery life but nothing more then most other email apps with the same settings.
have you tried as was lsited above and recalibrating your battery? I am assuming you are a pretty heavy user from the sound of things. How long where you getting pre root and how long are you now getting rooted? do you have titanium back up set up on a schedule? If so that can cause major battery drain as it sometimes keeps your phone awake.
All in all with the information you provided no one can actually tell you what is wrong. there are to many variabes and everything we say is a shot in the dark hoping to hit common problems.
my best recomendation configure your battery stats as listed above, if you havent tried use the HTC trick (chrage battery for 8 hours turn off phone charge for 1 hour turn on phone unplug it or 2 minutes then turn it off and charge for another hour.)
Anytime you wipe data you wipe your batary stats and it can drasitally impact your phones "battery life".
At this point I'm not so sure my battery or charging device on the phone isn't defective. But, only time will tell.
Currently I am running the newest, non-beta Myn TwoPointTwo and Netarchy 4.2 non-havs. I also ran this procedure (which fachadick already suggested):
1. Phone on...charge until green light comes on. Immediately unplug and turn phone off.
2. Plug phone back in until green light comes on again. Immediately boot into Recovery and wipe battery stats.
3. Use the phone on battery until dies.
4. recharge phone to 100%
I'm still on step 3. Will report back after a few days.
I had never heard of doing this when switching roms so hopefully it will help since I have swapped out a good amount lately.
Does anyone know where to get the newest HTC flashable kernel based on the new 3.30 release? All I have found is the rom package.
Hey folks!
I have the EVO 004 Supersonic. I love flashing my Android, and do it constantly. I am having issues with Synergy RC1 that just went live. My battery is draining fast, and I mean in an hour maybe two, I have to charge it. That is just being on idle, not being used. Drains much faster if I use it. I flashed back to my original image (stock) and the battery lasts longer. So I flashed Mik, and it lasted longer and I flashed CyanogenMod and that sucker lasted longer, but I LOVE the way Syngery looks and flows. But I cannot get the battery to last longer. So I thought maybe apps were running that are not supposed to, so I use my favorite app killer and the apps keep popping up, they are driving me nuts. Why the hell are they restarting? I want them stopped and NOT to reactivate. Is this an issue with anyone else, because I really do not want to get rid of this ROM. Also, yes, I cleared the Battery stats as well. Still fast drain.
Oh, one more thing, I cannot OVERCLOCK the damn thing either. So, those are my issues, cannot get apps to stay shut off (force close even), Battery is dying super fast and cannot get it to stay charged longer than two ours. Oh, and I already checked my battery with Sprint, battery is good, and they even gave me a SECOND one, and it still drains fast. Please advise.
Thanks for listening folks, and I appreciate any help. I love this site and has helped me NUMEROUS times, but I finally had post my own specific issue as I have never dealt with this before nor found anything that can help.

jeez...dead in 2 hours...and being idle?! that sux. i was running Synergy for a while and didnt have THAT bad of battery life (i maybe had 7-8 hrs before it needed to be charged again)
and of course you cant overclock yet...the kernel doesnt support it! it's still the stock kernel that came with the OTA...HTC still hasn't released the source code for the kernel so no custom "gingersense" kernels for us just yet (i.e. no HAVS, sbc, overclocking, etc.)
try some of the battery saving tips that Myn links to in the 2nd post of the Synergy thread...maybe that will help
question for you: why are you using an app/task killer!?!?!?! Android has one built in already [MENU >> SETTINGS >> APPLICATIONS >> RUNNING SERVICES (or MANAGE APPLICATIONS)] that could also be a reason your battery life is crappy (i really hate task killers so that last line might be biased lol but seriously...android does have it built it)

First, Synergy runs on HTCs stock kernel, they havent released the source code for the kernel yet, so there are no custom kernels for any evo 2.3 rom, so you cant overclock, or get the awesome battery life we usually get from custom kernels.
Now the battery draining is usually the radios. Right now I have wakelock on my phone running synergy, but I dont wanna mess with my radios, you would have to try different radio/pri combos until you find the right combo.

jeez...dead in 2 hours...and being idle?! that sux. i was running Synergy for a while and didnt have THAT bad of battery life (i maybe had 7-8 hrs before it needed to be charged again)
and of course you cant overclock yet...the kernel doesnt support it! it's still the stock kernel that came with the OTA...HTC still hasn't released the source code for the kernel so no custom "gingersense" kernels for us just yet (i.e. no HAVS, sbc, overclocking, etc.)
try some of the battery saving tips that Myn links to in the 2nd post of the Synergy thread...maybe that will help
question for you: why are you using an app/task killer!?!?!?! Android has one built in already [MENU >> SETTINGS >> APPLICATIONS >> RUNNING SERVICES (or MANAGE APPLICATIONS)] that could also be a reason your battery life is crappy (i really hate task killers so that last line might be biased lol but seriously...android does have it built it)

I use task killers because I can kill all tasks at once instead of individually. I would like to be able to close apps I am not using as well. But they keep popping up. I know now the overclock does not work with gingerbread, but man, I got a lot of misinformation.
I appreciate your help, I will try the battery saving tips, but if it is about letting the phone die, erasing battery logs and then charging it and then making the green light stay on when first plugged in and other stuff like that, I have tried it to no avail. I just flashed another ROM and the battery is FINE! It is so damn frustrating. I see others with great battery life. I just cannot get mine to do it.

Well, you guys probably will not believe this, but I got my battery to last a looooong time! I was messing with my battery options and decided to turn OFF the battery saving option it gives (enable power saver). I rebooted the phone charged it fully and then took it off the charger, BAM! Being FULLY charged it went down one percent after being on for 40 minutes. That is much better than I was getting on my stock and other roms. I just love this dang rom. Now, if I could only overclock the darn thing. So I have had the EVO on for 2 hours and 10mins and the battery says 97%, sweet. Anywho, battery issue is solved, loved it. Has this been mentioned before? Turning off the battery saver to save on battery? LOL. It probably has and I must have been to frustrated to absorb that info. Thanks for your help!
Battery saver...
I, too, was having draining issues on my Synergy-ROMed Evo. I could WATCH the battery drain. But I turned off the "battery saver" in power prefs and it's HOLDING STEADY! I'll report back if this doesn't turn out to be the cure I was hoping for, but it's definitely worth a try.
Now if I could just get this GPS to stop rebooting my phone...
Recently purchased the T-Mobile Samsung Galaxy S2 and I flashed Beastmod v4.2 onto it. I'm experiencing a lot of battery drain, approximately 10% an hour with very minimal usage. I flashed the same ROM onto an identical SGS2 and the batterylife on that one is great. I've tried reflashing Beastmod but still getting the same issues. Anyone knows whats going on or how to resolve this?
How are you flashing it? Wipe everything and fix permissions?
Sent from my SGH-T989
I flashed it following the directions on the Beastmod thread in development.
1. Download it and place it at the root of your SD Card.
2. Boot into recovery.
3. Factory Reset then wipe cache.
4. Flash the ROM then wipe dalvik cache.
5. Reboot!
Beastmod is still 2.3.5, you should consider flashing one of the 2.3.6 ROMs and maybe updating your Radio to the latest , much better battery seems to come with the newer update ...

Why would there be such a large discrepancy in battery life though from one T-Mo SGS2 with Beastmod to the other? That's what is making me scratch my head.
Did u do a battery Calibration? If not this might the reason why

Umm yeah that too ... duh ....
There is a BIG change in 2.3.6 in battery life, at least what I am seeing and others have reported, some say it is the ROM some say it is the radio , I am using both, I get better battery life, but overall the SGS2 Hercules is a battery hog ...

I have done a battery calibration on the phone.
Disable sync for your Exchange email. I found that to be the biggest source of drain.

A lot of this can be due to signal strength. If you're in an area where you're constantly disconnecting/reconnecting to the towers, or you're just below the acceptable level for 4g, it might be switching between 3 and 4g, draining your battery.
Another thing to note, you usually want to run a rom for a couple of days before you start judging battery. It takes a while sometimes to build the dalvik-cache, and calibrate the battery. Sometimes as much as 3 full charges.
Lastly, look at what you have running on your phone. If you've tried tons of different roms, and they all drain, chances are it's an app you have that's misbehaving causing wake-lock. I'd try downloading system tuner from the market, and first going into the startup section. Remove ANYTHING that doesn't need to run in the background. You'd be amazed how many apps run at startup that really shouldn't, at least until you start them yourselves. Battery spy and cpu spy can be useful for troubleshooting what's draining your phone as well.

Thanks for the tips. I didn't give it a chance to do 3 full charges yet and I'll take a look into removing startup apps.
From the OP, it sounds like you have more than one SG2 phone available to you. Try swapping batteries to see if the same rapid discharge occurs where transferred.

I did try this but the issue with the draining is still there.
Have you tried changing kernels? Each phone responds differently to kernels and like some more than others. I've tried everyone and Faux's "stock" kernel works the best on my phone. It's UV, on stock speeds with a screen off profile.
To make sure your phone is actually going into deep sleep check the app CPU spy on the market. it'll tell you what clocks your phone is running through and staying at for the most time.
Also, check out System Tuner to see what rogue apps could be running constantly in the background [se Bloatware Freezer to freeze or remove apps as necessary] as well as if your 2nd core is staying offline and not staying on when it's not needed.
I would also throw your phone into airplane mode and compare the drain with no data activation to how you normally keep it to check if the 3G/4G toggling is draining your battery.
EDIT: Please read this entire thread, there's some good info. Every phone and every situation is different, however it turns out my battery drain was the result of my phone not hitting "Deep Sleep". The culprit was my SD card, if you're experiencing battery drain after upgrading to ICS try removing your SD card and restarting your phone, use the app CPU SPY to verify your phone is now hitting "Deep Sleep". Again please read on, amidst some trolls there is more detailed information.
SIDENOTE: This being my first thread I have to say on the whole I really like this community!
I never thought I'd be that guy saying don't upgrade to ICS, because the OS is so slick and fun. However the glitch with the battery drain nullifies it's value. My brand new phone, less than two months old will die before the end of the day without me making a single phone call. I'm talking maybe an 1 to 1.5 hours of use texting, checking mail, surfing, and my battery now runs dead before I even get home from work. If you go into Settings > Battery it will show you the break down of what's using what. At the top should be your display, it takes a lot of power for to run the ultra bright display and this is what I saw before the ICS update. After the update these are the numbers:
Android OS: 58%
Screen: 18%
Cell Standby: 10%
Phone Idle: 7%
Android System: 2%
The OS is taking 58% of the battery?!? This is crazy!The buzz going around the net is if you do a factory reset it will fix the issue, well it does, but only for a very short time.
I went through the pain and formatted my SD card, then did a factory reset on my phone lost everything, well I backed it up, but still was a long process. After all that I loaded up my apps, and everything looked great. If you I went into the battery break down Screen was back at the top and the Android OS was several rungs below. I was SO happy! It was worth it after all.... THEN
Imagine my chagrin I woke up this morning to a full charge. Didn't make one phone call, just checked a couple emails, and being only a HOUR into my day my battery is at 76%!! I look back at the battery break down, and there's Android OS sitting at the top, draining double the battery juice as the screen display. I mean this almost makes ICS useless, what good is this great cell phone if you have to be tethered to a power cord. WTF!! Point being, don't bother resetting your phone, it DOES NOT permanently help. If you haven't upgraded to ICS don't, we're all just screwed until they come out with a fix, and you see how long it took them just to get ICS.
I don't know what happened between last night and today, but my hope is some dev person will read this and it will help them pinpoint the issue.
Did you backup and restore your app data as well?

Nope, the only thing I backed up was pics, music, and video, and I combed through those folders to make sure there were no sys files.
It sounds more like your battery is going bad. You can go to Sprint store and they will test your battery for you.
You might also want to get a battery monitoring program and see what is using the battery up.

its not a ics glitch its your phone lol.. ive never had this issue.. plus with the source kernels coming out and with roms/tweaks already out youcan increase battery life yourself.. because your battey cant keep a charge you bash ics? go back to gingerbread then lol. i can use my phone for two hours and leave it off charger over night and still have at least 50% charge

Having a bad battery would not make Android OS use the majority of his power though. I have had this problem myself in the past and never did figure out exactly what stopped it. Running Blue Kuban now and my battery life, though never great, is reasonable. FYI, I also run Juice Defender which makes a substantial difference for me.
Running pretty much stock ICS FF18, just have agat safe recovery/kernal installed. Yesterday I left Wimax on all day and when I went to charge it last night it had about 28% left. I made several phone calls, many texts/whatsapp messages, reading emails and using twiitter/fb a couple of times.
The battery life on this is not the greatest, for example, I forgot to turn off wifi when I left my house the other day, well my battery dropped about 30% in just a few hours. I now find that just leaving Wimax on all day is actually better and pretty much on par with just having 3G on, I prefer wifi at home but if I forget to turn it off it kills my battery.
I was so used to Blazers 4.1 battery life, the battery lasted forever and I could leave wifi, bluetooth etc on all day. Just hoping for the ROMs to start incorporating the recently released source so that we can get better battery life on these great ROMS.
This is all known information. That's why you use custom roms that have much better battery life.

I had same issue here with custom rom FF18 touched by SGS3. Went back to EL29, FF18 is glitchy and slower anyway.
Confirmed, factory reset battery drain exists.
OP, why don't you put up a screenshot of your battery graph? The expanded one, not the one that lists the percentages.
There are a number of reasons why this could be happening. One of my biggest drainers on CM9 was Google login service, turned out the "keep this device backed up with Google" in the backup and reset settings was completely preventing my phone from going to sleep. This is but one example.

You guys need to quit crying wolf and figure out what is really draining your battery. Maybe your google drive is syncing, or you have facebook running, or email is pulling too often, ICS does not kill battery rogue apps and wrong settings do.

seconded, attached is the battery stats for an average day for me on ff18 based goodness.... these "problems" are all able to be resolved rather easily with very little effort... this is not a paid tech support forum and no one is going to spoon feed you when solutions have been posted countless times in countless hysterical threads like this

My phone is not rooted and this is the battery life I'm getting after the OTA with light use. With regular use I get at least 25-30 hours.

Just curious, what's your display time. From the looks of it, doesn't seem like much. But still, that's pretty impressive nonetheless.

I'm a super n00b, if you or someone could link me to the best ICS ROM the cool kids are using I can figure out how to install it.
-----
However bottom line, before ICS upgrade my battery life was great and my Android OS was not 50% of my battery power. I'm not rooted or have any custom anything, after the ICS upgrade my battery drains rapidly. I'm willing to do what it takes to get it fixed, however I do fully put the blame on ICS, I'm using stock everything, the battery is good, something in that update is screwing my battery.
All I was trying to do was give developers, a little insight that the factory reset temporarily fixed the issue, for 3-4 hours before bed I monitored it and everything was good. So hopefully this will help turn the light bulb on in someone else's head.

ICS works really well for some, but for others it renders the phone completely useless. I'm one that it won't work for as well. The battery life is **** and 4g connectivity is non existent. As a result, I'm back to EL29/GB until a patch is made.
I spent 4 days after teh OTA was released trying to find fixes, trying to make it work, using different kernals and modems, but had no success. I posted about it many times and more or less was told that I was doing it wrong.
On that not, good luck mate. Here's to hoping for a patch from samsung soon. :good:

I have a thread stickied in general called "welcome to he et4g" that might be a good place for you to start, from there you'll figure out what you need to search for to learn more... there is no best rom its a matter of opinion, so read the dev threads and see what looks good to you... bottom line without seeing more information from you I would guess you have something running in the background preventing deep sleep, as mentioned earlier... also are you leaving wifi, Bluetooth, etc on? That'll kill your battery quick... do you live in an area with poor sprint signal? Constantly searching for service will also drain you battery. What do you have to set up to sync? And how often? There are easy ways to prolong battery life on ff18 and the vast majority of people complaining about battery life have not taken positive steps to learn more and resolve their own issues... it can be done, good luck
