The Best Battery life? - GT540 Optimus General

Pretty simple...
Of all the roms that you have tried, which one has given you the best battery life?

I was under the impression thats bugged somewhat, and that i would have to re-root etc.

You won't have to re-root as Joe's ROM is already rooted. But I think the 2.1 ROMs offer the best battery (Once calibrated that is) mainly all custom ROMs for our device have bugs (Except from 2.1 ROMs) it's just one of them things I guess.

I got 2.5 day with Mur4ik M4 after disabling akmd2 daemon.

I think at the current stage I might just have to try out EleganceSwift or one of the other ones or something...
Its my final year and I'm not spending too much time at home, and its really bothersome when I can't just use my phone to get a ride.

Super-Optimized Eclair by far, with constant music and games, it ran for 2 days, still leaving me with 30% battery to spare (then I re-charged, I bet I could of squeezed out another day and a half out of it)... I've done this without SetCpu screen off lower clock profile, with it, I bet it could run for 4 days of above average usage...

Black quarx rom 4and a half love it. And thats with a tonne of wifi and data use.

I'm using that rom for the time being too...I think I might have to calibrate my battery, but I'm recharging it now after calibrating it for another rom earlier (sorry if that doesn't make sense)
I'll let my current charge reach 100% and then let it discharge once more before I go calibrate the battery.
Mind you I had wifi,bluetooth both on while trying to waste my charge and it stood up for a fair bit...

Only stock, I've got about 131 Hours.

how to disable it???

goto system/bin and just rename akmd2

Anyone else notice 3g transfer takes far too much time?
My messages from Whatsapp seem to arrive fair while after my contacts have sent them.

Can you tell me what are the things that I'll be losing if I disable akmd2 daemon? What is it for?
srpski: Sta gubim ako ovo iskljucim?

Just use root explorer and rename it, if anything starts going wrong on your phone just rename the akmd2 file to the original name.

battery time just fell off

without doing anything new my battery time just droped off the face of the earth.. its down about 75%. i was getting a full day mixed use now all of a suden im getting 6-8 hours with just a few phone calls.
my awake time is at 16%
I havent done anything new that i can think of.
im using (and have been for awhile) the mugen 1800 extended battery.
trying to think what might be doing it and cant come up with anything i havnt found in the forums already.
you probably downloaded some app that is running in the background continuously. check with a task manager to see what's running, and then try uninstalling some recent apps to test it out.
thats what i was thinking but i cant find anything new running with the task manager

Could just be a bad battery? I'm having same problem, maybe worse with stock battery. I went from 100% down to 15 in like 5 hours just reading my RSS feeds every hour or so. I think I may have fried my battery using it to tether for excessively long periods.
You're not using your phone to tether are you?
Mine is way down this week too. Initially I thought it was Swype, but not so sure anymore because no other users are reporting problems.
Are you using Modaco's rom and kernel ? or any new kernel for that matter? Ever since I switched kernels my battery hasn't made it through the day.

I'm using gbhil's custom kernel and seeing BETTER battery life when used with setCPU (using ondemand setting with 'standby/sleep' profile turned on, and set to 160/480).

No I'm not.. Turned a few more newer apps off and still no good today.. I was at 5% batt left after 9 hours with about 10 minutes web browsing (not wifi) 4 or 5 text messages and about 45 minutes talk time. That's down about 90% from were I was a week ago .
I managed to narrow my problem down to the Taskiller widget. Removed the widget (still running the app full time) and all is well.
Last night I rolled back to before I used a custom Kernel. I rather battery life over speed. I need my phone to last from 6am to at the very least 7pm. I think once people get over the performance boost, we'll see a lot more posts relating to battery issues.

might be that too, i hope not as i love that keyboard. just having it installed shouldn't drain the battery, should it? im on day 2 with the custom kernel and i too noticed more battery drain. at 1pm my hero was fully charged. i only played a bit with the phone and made two short calls and it's down to 86% already at 4pm. i want to roll back but i do like the speed of the new kernel. ill see how it does tonight.

Yeah going back to regular input sucks. Swype was only some leaked beta version, we don't really have right to complain; however, I bet their end product will be much better. I just hope they'll release it as an app and not as part of custom Android phone so we can get it sooner.
figured I woud resurect this thread rather than start a new one.
yesterday I decided to RUU my phone to pull the completely stock apks out of it. after I did that I restored my backup of fresh 1.1 with gbhils kernel and now I am at 90% awake time spare parts shows that "android system" as something keeping it awake. any suggestions on what this could be? could it have something to do with restoring the back up with the kernel over stock without a wipe?

Battery problems? Google lies?

So I found this great app that tells me how much life I have left on my battery. I find that with my phone I can hardly go pass 16 hours with MODERATE use yet everyone here is bragging about easily passing 30hrs with HEAVY use. So I'm asking you guys, to please, download this app called BatteryTime Lite and post your pics or info here. Lets compare the results. Remember to set the level to 100% as shown in my pic below..
Also I herd the P/N might be related, mine is 99HKE002-00 F ..Guessing F means Failure.

Thats what I herd too..thats why I'm also calling google a lier about saying this thing lasts 20hours with audio playback.
I'm curious, do they see a big improvement in battery when the display using 15-20% battery or its just numbers that were out a place to begin with?
I have identical figures. That combined with picking the N1 from a list says to me that these are just database figures rather than real world ones for your handset.
Root your phone and then install cyanogenmod and one of the under volted kernels. I usually get 24 - 30 hours battery life.
I just ran a test. I left the mp3 player on all night turn all the way on repeat. SO far after 8hrs of playing I was at 52%. If I'm correct, I just might be able to hit 18hrs...MMMM

No problems at all? no 3g issues?, battery only lasting a day or half? or touch screen issues?
Ok after 100% charge..the app is telling me that my phone will last 10hr:48min with moderate use....anyone thinking that the F on my P/N might mean battery sucker..
i have the exact same numbers as you. if you choose other instead of the phone type it asks you to enter your battery's info so it sounds like it only goes by the type of battery anyway. Not actual usage specific to your phone
My phone ends in an F as well. My battery life SUCKS right now. I have tried everything. The weird thing is it was good until I rooted my phone and applied Cyanogen rom. I've tried .2 and .3 for the Cyan rom's, all with bad battery life. I've tried wiping batterystats, fulling draining battery then recharging, task killer to wipe anything in the background, I even have a 2nd battery. No luck. I've also tried the undervolted kernal, but I didn't really notice a difference with it. (Only tried it for about a day so)
Bottom line though, something is going on. Something (I suspect with Cyan's roms) is killing battery life for some of us. I just wish I could figure out what it is.

Any chance you're using Weatherbug or Weatherbug elite (based on your SS)? After installing weatherbug and using the widget I got absolutely ABYSMAL battery life. I've purchased several other weather widgets and none had the effect that Weatherbug did for some reason. I removed it and battery life is back to normal again (moderate use and plenty of battery at the end of the day).

battery lasts 1.5+ days
3G (at&t) is almost ALWAYS there and quick as balls
palm reach thing is gone.. i mean, i had the t-mob version before this one and its exponentially a better experience all around.
data is QUICK too... i mean quick
How long your battery lasts definitely depends on the apps youre using, I use my phone a lot, probably more than the average user, although i dont make many calls. My phone will easily last from when I leave my house around 530am till 11pm or so when I go to bed. I do use a task manager to kill stuff I dont need running every once in a while, I think it really just depends on how you use it. I use it for a lot of texting, surfing and news, and Pandora at work. I use wifi when im at home although ive never noticed it eating my battery. Yesterday I was playing Pandora over bluetooth on 3G for a little over 3 hours and it only took 5% of my battery. Im on Cyanogen 5.0.5.3, if that matters. With all that said I rarely go all day without charging it, I usually plug it in a bit at work and plug it in when I get home, but if I dont for whatever reason it easily lasts my whole day.

Which ROM gives the best battery... period?

Does anyone know? My guess is MCR or Enom... but I can't be positive. Anyone?
Im waiting for the next release of cm, if it wont improve my battery life i am going to systematically try out all the other mods to see which one gives me the most juice.
Ive had my best battery from Kings Nexus rom. Its undervolted and has easily been the best battery one.

Thanks... I'll be using the AVS kernel, so I'm more concerned with ROM (not kernel) performance...

For me its Alpha r20 - MoDaCo Custom ROM Desire Port this rom is great or me r21 was not as good for battery life i dont know why wish i did
From worst to best:
-CM
-Enom
-Desire
Hmm... I WISH I could go to Desire but I NEED Bluetooth. What about regular MCR?

Can you put this in context though? What was your battery life like previously? What ROMs have you used? What kernel are you using? Where can you even get 5.0.6?
Yeah battery life has to be tested to a standard method one good way to test would be to play a movie with the volume at Max with high brightness or transferring one big file over wifi for a period of time and see how fast it drains. This will act as a stress test and will bring comparisons a lot faster and more efficiently.

The one that doesn't allow you to turn on the phone. Battery lasts for weeks!
In all seriousness, using stock rom gives me a very good battery life now, lasting more than a day with almost everything on, 2 push emails, full brightness and all 3G.
CM 5.0.6 T2. so far ive got a full day of usage out of this rom with 3G all day. setcpu profiles enable. Gtalk, Twitter, Emailing. 5 or more phone calls 15 min each. Two app downloads from market.
But if i was just going to play and show off i had use Enom rom and its far by the best. for battery life. CM 5.0.5 i didnt get great battery life. i could leave my phone over night 100% and wake up to it on 80%-70% or so. with nothing in the background
An undervolted CM 5 may give you a better battery life...
Waiting for 5.0.6...
Cyanogen 5.0.6 is far and away the best ROM I've used, power wise.
Up to 5.0.5.4 I was seriously considering getting rid of my N1, as the battery would lose 80% in less than 10 hours, just sitting on standby combined with less than an hour's worth of web browsing.
5.0.6 is much better, and I'm still showing 50% after 16 hours.
Still not a patch on my old Nokia 5800, which went 3 days at a time on a single charge, but at least I have the confidence to actually use my N1 now...
I'm sorry I call BS on anyone who claims they use their phone AND get more than a day battery life. Until someone is willing to give me a Nandroid backup to restore to my phone to see what it is that is running and prove that their programs and background processes make for a 20+ hr battery, I don't buy it.
I'm off the charger since 8am and am down to 91%... it is ridiculous. I'm on an AVS kernel and Enom with not much running in the background.

Is that aimed at me?
I have a Facebook widget, along with the standard news and weather widget running, and email (NOT the Google mail app) set to refresh every 15 minutes.
I use the browser (on 3G/HSDPA) for up to an hour, here and there, and about the same on wi-fi at home.
GPS is always on, Wi-Fi and bluetooth only on when required.
The Last.fm app also gets used for up to an hour, although not every day.
Couple this with the odd phone call and text message.
The above would see my battery down to less than 20% after about 10 hours, and was really annoying.
The past few days, when I went to bed the battery was hovering around the 50% mark - although I've not used Last.fm this week.
Of course, this may not meet YOUR definition of phone usage, but it certainly isn't BS...

Appropriate steps to a better battery life?

Hi everyone! Long time XDA reader and I've had my Evo rooted for months. Now I have been dealing with its "poor" battery life for a long time and not really thinking much of it till I finally decided that rooting has to have some advantage for this. I average about 6-7 hours then my phone dies...
After doing a little research I read some people getting 15-20+ hours out of their phone with heavy use...I was amazed...I decided to try to get better battery life on my phone and this is what I am trying right now. I just want to make sure I am on the right path with it and that I am not doing anything seriously wrong.
-I am trying Cynogens ROMs - CM7 I tried for a day and that gave me about 7 hours of battery life...still no real improvments. I am trying Cynogens 7 Nightly 12 now to see if that works.
-I am trying different Kernels. Been getting them on the HTC EVO kernels page. Right now I am using stock HTC one.
-Should I try different radios too? Where can I go to find different radios if so.
-What order should I be installing radios/kernels/roms?
-I have donated and am using Set CPU now also and have the screen off cpu power really low.
-Am I on the right path trying out different ROMS/ Kernels/ Radios to optimize my battery life? Is there anything else I can be trying?
turn off gps when not need
data when not needed
Check out my sig for my full walk-through on battery life (I don't want to repost it here lol).
But you seem to be doing everything okay. My only hesitation would be to say make sure you're giving Kernels adequate time to settle into your phone. Unless something is HORRIBLY wrong with them, you shouldn't switch/judge them until at least two days in
Radios should not make a difference in your battery life.
Also, be aware that CM is NOT optimized for battery life. There are a couple of ROMs that will give you unheard of battery life if you would like though (Myn's comes to mind). It's a trade off though. CM is hands down the fastest ROM you'll run...but in my experiences is in the lower tier of battery.
Hope that helps
also when the newest version of ultimate Juice is released that will help you i have the closed beta and im glad to have it back and running
@Cheesy: I turn off all those things If I turn off "data" that turns off Exchange push right? I really need that on all the time >_<
@Green: Really? Myns is good on battery life? I tried that before and was dieing with battery. (Was getting my average 6-7 hours) I had that one for about 2 weeks. Do you think it was my Kernels that were bad then? Isn't Myns warm 2 pt sense based? The one I used was...I had thought sense UI drained battery more than CM for example that is just plain stock android gingerbread?
@Cheesy again: Ultimate Juice? Is that an app on the mkt place? How much did it help you? I'm willing to donate and pay for apps to support the devs if they really make a noticeable difference.
Another thing..when you install a ROM does it automatically install a Kernel too? Or are those 2 separate?

with UJ i get 18-19 or more on a full charge with phone being used 80% of the day .
with out i was changing out batteries after 9 hours or so ( i normally work 12 - 13 hours a day )
yes its in the market but gingerbread support is not public yet ( closed beta )
also check in spareparts for any wakelocks you might be having
for a sense rom myns are great so are Ava's,caulkins and Miks
Hmm Thanks Cheesy. I'll take a look at that.
So if I flash a ROM that is not Gingerbread...I can use that app. But Gingerbread is anything 2.0+ right?
I'll try out those ROMs too and different kernels...test them for 2-3 days.
Whats wake lock? I'll download that spare parts thing and see if I can figure it out.
I just recently started seeing great battery life with my rooted Evo. I flashed MikFroYo 4.5 with a stock htc kernal.
I use juice defender and that's it. I've been getting just over a day per charge for the past two weeks.
I wouldn't say that's with heavy use as a good 6-7 hours of that time are accounted for when I'm asleep. I do about 30-50 texts a day. About 10 minutes of calls and I check facebook and twitter all the time. My data use varies depending on the day but I do use youtube and pandora pretty regularly as well.
just make sure background data is disabled. accounts and sync>background data. I have no issues with battery life on stock sprint evo.
of course it is a 3500mah battery
My wife and I just bought two EVOs a week and a half ago, and I quickly became interested in improving the battery life on the phone. My first attempts were rooting my phone and installing OverClock Widget, and using minimal settings when the screen was off. With that change alone, and comparing to my wife's phone from a full overnight charge, my phone was able to make it 14-16 hours with moderate use. My wife's phone would die after 8-9 hours of moderate use. Granted, there's obviously going to be a difference between my moderate use and hers, but even testing with screens off and letting them idle for an hour, there was a definitive difference in battery consumption between our phones.
I went one step further and installed CM7 Nightly 12 just yesterday... already I'm noticing even further improvement in battery life, but the majority of those savings are when my phone is idle. Overnight, my battery only drained 7%, whereas my wife's drained much more than that. My battery has been at 39% for the past 3 hours at idle, so I imagine that with my version of "standard usage", I would be able to possibly get higher than 16 hours of usage per charge (can't wait until I do the full calculation testing tomorrow!).
Here are some observations I've had in all of this:
1) Check out Greenfieldan's list of battery tips and tricks. Some of these are very simple and actually had a significant impact on both my phone and my wife's phone (especially shutting off data and disabling auto-synch). I'm new to the forums, but this is one of the first things I checked out. This is a great place to start.
2) Battery consumption is obviously affected by how frequently you use your phone, and what you are doing with it. I say this because it's easy to read threads about what techniques work and see mixed results, but I don't see alot of people really admitting how much or how little they use their phones. I'd say I'm a more conservative user of my phone, but I still have my texting, browsing, and even occasional streaming, GPS using and general fiddling. So in other words, your mileage may vary with any given technique.
3) This is my personal opinion, but think about when you ideally want to be charging your phone, and try and anticipate usage around it. It sounds strange, but I've come to my own conclusion that an optimal charge for me (not necessarily possible, but optimal) will give either 12 or 36 hours of usage time. This is because I like to charge my phone overnight, so if I get 18 hours of battery life, I'm unfortunately wasting 4-6 of them. If I get 24 hours of usage, then that means that by the next morning, I need to charge again. So I plan ahead and charge at night, and use through the day. This was particularly useful when I first started with the phone and was getting a max of 8-9 hours. I'd know when to unplug, and how well it would get me through the day.
Anyway, at this point I'm rambling, but since it is still very fresh in my mind I wanted to share my thoughts. Hopefully this helps.
(Btw, apologies for the huge post!!)

Gingerbread is Android v2.3. Froyo is v2.2.

@Cheesy: I turn off all those things If I turn off "data" that turns off Exchange push right? I really need that on all the time >_<
@Green: Really? Myns is good on battery life? I tried that before and was dieing with battery. (Was getting my average 6-7 hours) I had that one for about 2 weeks. Do you think it was my Kernels that were bad then? Isn't Myns warm 2 pt sense based? The one I used was...I had thought sense UI drained battery more than CM for example that is just plain stock android gingerbread?
@Cheesy again: Ultimate Juice? Is that an app on the mkt place? How much did it help you? I'm willing to donate and pay for apps to support the devs if they really make a noticeable difference.
Another thing..when you install a ROM does it automatically install a Kernel too? Or are those 2 separate?

Sorry it took me so long to reply.
Anyhow, from my testing on mine and three other phones Myn's Warm TwoPointTwo has the best battery life (although some of them were right on par with it). Specifically his RLS 3 and RLS 4. Did you try Warm Z? Because the battery life on that ROM is no where NEAR his 2.2 ROM.
Also, Sense CAN be a major drain on battery. If you make it so it's not syncing all the time/doing the random shenanigans it defaults to I'd argue it's better than AOSP (based on my experience with both).
Yes, your Kernel might have been an issue. Do you know which one you were using? HAVS? CFS? BFS? Etc.
Just for my phone comparison, CM7 (which I am running now) requires me to charge my phone at least once a day. Myn's Warm TwoPointTwo was every other day/every day and a half.

You can set juice defender to turn on data to sync at set intervals; anywhere from 15min to every couple of hours. If you can stand to wait 15 minutes for that email then I would recommend it. I personally like not being interrupted every time I get an email.
Also, make sure your kernel and setCPU aren't trying to both control the same thing. I really like using a kernel with HAVS so I avoid apps that also try to modulate my CPU.
I've tried warm 2.2 and really like it. Although I think I'm getting slightly better battery with Azrael X 4.0 with netarchy 4.3.1-cfs-havs-nosbc and ultimate juice controlling only my data and WiFi connections.
Also,the 3500mah battery is worth every penny if you don't mind the extra thickness.
i owe setcpu and screen off seting for my battery life
I read Greenfieldan's step on the forum here about a week ago, and jsut the HTC Method of battery calibration alone changed my battery life completely.
I also dumped Advanced Task Killer.
In another thread, I rad that CM is the worst drain on a battery and I personally think the guy that wrote that is sadly mistaken. Even with all the steps taken in Greenfieldan's guide, Sense based ROMs are battery killers. They are the worst, by far, and I average battery drain at about 15-20% pr hour, even with screen off.
The #2 killer, is having your screen on. Waiting for that next text to come in with the screen on is not worth it, so turn it off when you're not using it.
With the setup in my sig, and moderate to heavy use, in 12 hours, I only drop about 25% with a Sedio 3500maH battery.
With Sense, like I said, quick battery death.
I'm using CM7 - Nightly 12 right now + Stock Kernel...I also have set cpu to change cpu usage when screen is off.
This combo was my first combo I started trying (2 days ago when I posted this) to test for increased battery life. I followed what some of you guys suggested and let it "work into my phone." Instead of giving up after 1 day of test.
Results! Just yesterday I had my phone on for 14 hours and it was at 18%! That is a HUGE improvement. Right now it is at 65% and I've had it on for about 5 hours. That's really long compared to what it was before! Before I tried changing the ROM, kernel and using Set CPU I would be at the red right now or around 15%.
Thanks you guys for all the suggestions! Any further advice would be greatly appreciated! (Only sad thing is that my GPS doesn't work with CM7 - Nightly 12 >_<...) Other than that I love it!

[ICS] We need your help... Battery life...

Since the beginning of Android one thing has always been an issue with some of the greatest ROMs.
........................Battery life.
Every day lives are drained away by the pleasures and features of such fantastic ROMs... and such things at time seem so hard to bare that we try to change the lives of our battery by going to a different ROM.
So now you have a chance to make a difference, nay, an opportunity to change the lives of many...
This thread is strictly for how to save Battery life. CM9/AOKP have amazing battery life by themselves (but yet can always be made better) But for those on MIUI (Not so great battery life) this will be really useful.
Understand that everyone's device is different and although you may get 15 hours off MIUI/AOKP/CM9 others may only get 4 from them.
Post what it is that helps you achieve maximum Battery life. You may be the one to solve the cure to wowhowdidmybatterylifedroptwentypercentinanhourosis.
Be sure to include:
1. ROM
2. Kernel
3. Tweaks that have been applied through ClockworkMod
4. Apps used to save life
5. What battery you use
6. How long your life lasts
7. Anything else that you think may help

I think the OP is looking for more practical solutions where they are not disabling major features of the smartphone.

1. CM9, although i think aokp does better.
2. Samurai Kernel, although just about any other ICS kernel should help. The biggest thing that you can change between kernels is the Governor and I/O depending on these two will determine how the CPU runs and in effect will determine battery life. Conservative is just about the best for battery life. If you need slickness and not too worried about battery Ondemand. If you want the best of both worlds i Think Wheatly is a good compromise. Also I/O , Sio is "simple" but VR is flash based so it tends to be the best. Otherwise Noop/Deadline. Also voltage.. undervolting will help limit the amount of well voltage to the CPU. So the lower you can get it the better.
3. Dont have tweaks i apply through CWM but i Run the V6 Supercharger, 3G turbocharger(optional), and the Kick Ass Kernelizer from Zeppelin.
4. I cannot stress this enough, Apps that say they save battery... run... which uses RAM and Resources... meaning its running trying to save you battery, Using battery. Which is stupid... and useless.
5. I have two a 3500Mah and the stock 1.5 year old 1500mah.
6. Typically with 3 hours of display over a period of 15hours (1500 mah) and around 5 hours of display over a period of 22 hours (3500 mah). However this is on wifi, 3g would deduct these a pretty good amount if you have sucky speeds.
He needs to get over it... lol. The only thing that truly saves battery life is managing your connections. There is no magic bullet unfortunately.
PLEASE! Don't tell us to turn off data and never sync the phone. Obviously if you don't use the phone the battery will last forever. I need a phone that can do the following:
Receive emails and texts as they are sent. (I use exchange push)
Last 18 hours on a standard or 1800 mAh battery.
I can just barely make that with stock FC09, I'd love to run ICS but with either CM9 or AOKP I barely make 10 hours.

Why must people post unhelpful comments such as the one above? I don't understand the logic there...
anyways since this was aimed at miui I get pretty good battery life with it... (3.5 hours screen on time) nyan v5 ftw! No special features... uv a lot (won't list my settings cuz every phone is different) and no oc... used to use jd but, it saves more battery if you just switch things off manually... really though until I flashed nyan my battery life was atrocious, but now just about on par with the peoples rom (4.5 to 5 hours screen on time!) Oh yeah, all this with the stock battery...

On aokp with 1800 mAh i can do about 3Hours of screen on time and 15 Hours of battery life and my phone was awake 75% of the time.
Screenie was at 15%
This was stock Everything Except ROM haha

Think about if your screen was on while the device was awake..your time would be cut in half

Oh my good golly gosh.
I just realized the best battery life I ever got was on DK28.
So take that. Let's go Frankenstein.
1. CM9 KANG June 02 build.
2. Stock
3. Services for V6 and Search Key Remap
4. Ha!
5. Stock. Came with device...need new one.
6. Depends on use. But I usually get the estimated six hours consistently.
7. If you're going to use a task killer just use the built in one. Overclocking is bad, and in my experience so is undervolting. GTalk, official Facebook application(especially this. Even with notifications off it still is always going), G+, and more are always running and are a drain. No live wallpapers, and no widgets that require constant updating. As much black as possible. Don't use third-party batteries. Obviously turning off 3G, 4G, sync, and such will dramatically increase your battery life.
WAIT! Why am I writing this? There is a freaking optimization guide. Why does this exist? For ****s sake.
Running AOKP build 36, stock, FC09 modem 15 hours running takes me down to 50% batt hour of screen time, constant crappy wifi connection in an area with crappy cell signal sync for everything but email and g chat is every 2 hours (weather and all that). Big thing to save batt for me was turning down my screen brightness. I was also getting crappy battery life till i let this rom install run the battery down to 5% twice.

By no means was I saying never enable your 3g/4g.. but the fact remains that the single best way to conserve your battery life is to be smart about managing your connections. I.e. not leaving it on ALL day and to only turn sync on when your actually checking your e-mail.. be that through an app like juice defender or manually toggling. If that's not more helpful than what you posted (UV a lot and don't overclock??? Duh.) than my bad bro!

-THIS +9000! An app that spends all of it's time stopping other apps is wasting just as much "battery." I maintain, Advanced Task Killer, with NO, I repeat NO AUTOKILL. Set a widget on your home page, tap it occasionally to make sure everything is closed. Same effect as the built in task manager, but one single convenient tap.

I NEVER turn off wifi or 3G, but google autosync is off until I edit my contacts.

Firstly, I'm not trying to get into a pissing match with you. Its pointless. Secondly, the op makes no mention whatsoever of connection status. Thirdly, while you might get decent battery life w/o doing it.. I guarantee you'd do better if you did. Straight facts.
Edit: I am armed. With a small slide out keyboard.
Please follow the format specified by the OP. List the 7 items. Bickering in this thread will not be tolerated.
Thank you for your cooperation

1. CM9
2.ShadowKernel (I find nyan colonel to be a little more draining) SIO, conservative
3. None
4.System Tuner Pro configured to UV, under clock to 400mhz on screen off, to close apps that don't automatically restart themselves, configure "auto-kill" so its not as aggressive with killing apps that just stay on, and a few sysctrl edits that I honestly don't think make a difference.
5.stock epic 1500 mAh, my sprint store wouldn't give me an sgsII battery
6. 12-18 hrs depending on use, though it has definitely drained quicker
7.be easy on data! (There kennyG) turn off wifi when your not near your networks, turn off mobile data, Bluetooth, and autosync when your not needing it. (Unless you absolutely need PUSH email for your job or whatever though honestly as far as my job goes if its important enough for me to need the message immediately they will simply dial my phone number. Yeah I'm old fashioned.
- Cm9
- Shadow kernel
- No tweaks
-1800 D710 battery
- I get 15-20 hours depending on how much music I stream during the day.
- I got the biggest boost by using the profiles in CM9 to optimize my connections and syncing depending on where I'm at during the day. I have Wifi at work and home, so I have it toggle my data off during that time period and vice versa when I'm mobile.

Using AOKP with shadow kernel.
Best thing I did to help with battery life was to turn off all notification options in the FB app. And I set haxsync to download photos only when plugged in.
