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...
EDIT: Also - I can't use Desire because of Bluetooth.

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!!)

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!

Looking for a great Sense 3.0 GB rom with good battery life

hello everyone. I have been using Cyanogenmod 7.1 for a little while now. I am getting tired of it for right now. I am wanting to try something with sense 3.0 and GB rom. Which one's are great and fully working on the Evo? Also do any of them have better battery life?
P.S. I am currently trying out Synergy rom. My friend has the LG phones on Verizon and man they get awesome battery life. 12 hours off the charger and his phone is only down to 73%. He has been making a lot of calls but man my Evo was off the charger for 16 hours and was down to 15% and I barely even used the phone. I hope the Evo 3D has much better battery life, otherwise I may buy an 3500MAH battery for my evo.

Battery life varies from phone to phone anyhow

ok thank you. Looks like I'll be flashing and testing out roms today, thanks again I will report anything else here.

Alliance Rom is pretty
Evo 4g

MikG-c2.15 is working very well - no issues at all. Battery easily lasts a day with fairly heavy use. This is probably the best ROM I have ever had on the Evo. (and I have tried MANY.)
RECOMMENDED.

I love Synergy and MikG but I can't use them as an everyday rom because of the battery life. With Synergy I watched my battery drop to 70% in like three hours after I had my phone off the charger for a few hours yesterday morning. And I had barely touched the phone! That is completely unacceptable to me, sorry. I need my SBC and HAVS. I wanted to go back to MikFroyo but I have an issue with the display usage (stays at like 90% even with the screen off and not touching the phone) that drains the battery in like 10 hours.
Tried to go back to my Salvage-Mod nandroid but it somehow got corrupt. I almost went back to Myn's twopointtwo but I didn't want something so outdated (still a great rom though). So here I am now using CM7...not the biggest fan in the world but it works and it's giving me great battery life with Tiamat kernel 4.0.5. A little over 20 hours with medium usage.
I don't understand what happened with MikFroyo. I never had the display usage issue before. Then it just came out of no where and stayed like that. I tried going back to 4.5 (which I know for a fact it didn't do that on) and it still did it. Tried switching kernels, nothing. I used to get 25-30 hours with a charge on 4.62, and Salvage-Mod gave me the same battery life. So I'm just hoping that new kernels with SBC and HAVS will let me be able to keep Synergy or MikG as a daily.

Keep me updated. I have been using Syngergy today and battery life is ok. I would go back to CM7 but having all of the random reboots when 4G is turned on kinda got old.

I need my SBC and HAVS,. also, but you DO know you cannot judge battery life right after flashing the ROM, right? You DO know you have to let it settle in for a day or 2, right?

this is with 28% remaining after heavy use
this is with 12% remaining after heavy use (ignore the 28% in the header...)

Evo Battery life

I just typed out my post and got the Mac equivalent of a BSoD and lost what i typed (wow fist time that has ever happened to me).
Flashed Decks, I have tried both tiamat and SavagedZen kernels. Followed a few different guides and no luck at all batter still stucks. Today my stats were as follows. 4h 55m on battery with very light to little or no usage at all and battery is at 10%. When i had it on stock ROM have much heavier usage and was never that low before. I rooted to get rid of bloatware and my main reason for AOSP ROM was to get away from sense messed up BT stack (want to use Wii controller), but if this is what I'm up against I will stick with a sense ROM (probably go back with fresh had with my hero and it worked well). is this the norm for ASOP? Ive seen other post about better battery life on sense ROMs. is it just how it handle the system different I already followed this one here:
http://forum.xda-developers.com/showthread.php?p=19474607#post19474607
And couldn't get it working fully. Does anyone have any other suggestion. Different ROMs, kernels, setting I could try as a last shot. Would prefer a basic ASOP with good battery life, and most stuff working (don't know if that's to much to ask).
Thanks in advance.

I don't think that 5 hours of battery life should be considered normal for any ROM. If that is all you get from a phone then something is wrong.
Have you tried wiping battery stats in recovery? Sometimes the software just reads the battery level incorrectly. It would have to be pretty far off to claim you were at 10% after only 5 hours but who knows...
You can google it but the typical process is to charge it up to 100%, wipe battery stats, then reboot and unplug. Drain the phone until it's absolutely dead then you charge it fully again and it should read the battery level more accurately. Apparently it is bad for Lithium Ion batteries to be drained completely though, so it is not recommended to do this often as it can shorten the overall performance of your battery.
I haven't seen much of a difference in my battery life using Cyanogenmod 7 or MikG (currently running 2.58 but 2.60 is out now). I personally really prefer sense ROMs and MikG is definitely the best one I have used. Give it a shot. I have gotten 60 hours of battery life on the stock Sense ROM (granted, it was with almost no use) and over 30 hours with pretty decent usage. I posted some youtube videos to demonstrate this since I figured everyone would claim I doctored photos:
over 50 hours (wound up being 60 hours by the time I finally unplugged):
http://www.youtube.com/watch?v=fGJucqVw0RQ
32 hours:
http://www.youtube.com/watch?v=SPqtsRDRYEs
I have since moved to MikG but I pushed my battery again last weekend and got another 30+ hours of it. I'm extremely happy with my battery life!
I am sticking with MikG over CM7...I have too many issues with CM7 and there just isn't enough to keep me there. I was going to write up a huge post about that now.

yea i actually did wipe that stats. Ill probably just do a full wipe and start fresh with sense rom and see where it goes. What are some advantages of mikG any features that make it special over others? What version of sense does it have? Im downloading right now. is there a info page of what all it includes? i couldn't find much info for it.

Im in the same boat some what, but I will say your time should be better with no use. Im not getting huge battery increases with aosp roms when using the phone. Im better off with the stuff that worked well on sense roms for me with no tinkering (gps, slow sd speeds, updating prls, etc)
Im convinced the people that claim these lengthy phone hours dont use their phone besides texting much even if they say otherwise. Most screen shots I see rarely even have voice calls registering. I think the best way for "me" to get a full day is to buy an extended battery. Im not on wifi all day, Im in and out of low signal areas. I need to keep data on due to emails for work. Maybe Ill run into a miracle rom and kernel, lol
I do like the classic rom which I backed up and I will try some others today (fusion/hyrbid ex1)

I always wind up back on this ROM. I just think it looks beautiful, it is fast, and it just works. I use GO launcher EX as my launcher by the way. I highly recommend it no matter what ROM you use.

I totally agree with you with is why if you watch my second video posted above, I actually go into the usage screen and tap on the things to show what I am using. 50 minutes of voice calls, 25 minutes of words with friends, 41 minutes of GPS, Bluetooth on 100% of the time, etc.
But typically when I see those you tube videos I see people saying they were using their phone heavily and got 25 hours out of it. If you look closely in their battery stats screen though, you'll see that cell standby was the top battery user. That refutes the heavy usage claim right there!

How is this possible? I'm on 1500 stock Mah battery on a fresh sense rom 4.3.2 my battery wont last that long even if I reset battery stats. But running on cm7 with stock it does pretty well avaerage 15+ hrs depending my usage.

I always wind up back on this ROM. I just think it looks beautiful, it is fast, and it just works. I use GO launcher EX as my launcher by the way. I highly recommend it no matter what ROM you use.

I put FreshEvo and it looks like battery is holding up well. I got MikG tp play around with..(it does look beautiful). A few quick question about it.
1. Does it have the native hotspot app unlocked or just wireless tether?
2. Has CarrierID been removed or disabled?
3. Should I use the default kernel in the rom, or is there a particular one you use.
Thanks,

2. I don't even know what you're asking here sorry. Do you mean you want to use it on another carrier besides Sprint? If so I have no idea...maybe post your question on themikmik forums.
3. I use whatever kernel MikG comes with. Some people like to flash other ones, but I have never messed with new kernels, regardless of the ROM I'm using.

Great! I have found MikG to be awesome so I'm glad it works for you too. If you want to upload a screenshot then tap the power button and quickly hit home. It should take a screenshot. Then if you want to share it you can go the gallery app and tap the share icon (circle with 2 arrows). If you want to attach it to a post here from your phone (xda app) then start a message and then tap the more button. You should be able to attach something from the gallery.
I just posted pretty much the same info at themikmik.com but it was more detailed. I'm on my phone right now but I'll go copy that link and paste it into an edit here.

Senseless MikG 2.9 has gotten me over 2 days of moderate usage consistently. This however does not include 4G since I can't get a signal anywhere >_<

I use CM7.1 + SavagedZen (latest) SBC (BFS) and get between 40 and 60 hours depending on usage.
I am also using the Sprint extended battery, however. By my estimation, this accounts for roughly 8 - 10 of those hours.
The kernel made a HUGE difference. Tiamat 3.3.7 was only getting me about 20 hours tops.
Phone is also undervolted, and supercharged. No overclocking or underclocking. I am incredibly pleased with this phone - definitely can't switch phones unless I know that I can get something remotely close in terms of battery life!

Simple solution, sell or return the Evo and get a 2nd generation windows phone mango device such as the Focus S or Titan or Lumina series, or even a first Gen such as the Focus. No more constant rom flashes, force closes, lag, and horrible battery life.

[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

Eclair
Just Eclair
Any Eclair
Shoot me......
But seriously, disabling 3g on ICS saves a ton of battery life.

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.

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.

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!

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.

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.
