UPDATED MY SETTINGS
So as many other users I've been having lots of problems with battery life. I've done so many things in an effort to try to improve battery life but it doesn't seem to improve as much as it has for other people
This is what I have done:
Installed Baked Snack 9.7
Have brightness set to automatic
Changed the preferred network type GSM Auto (PRL) to CDMA Auto (PRL)
Installed Juice Defender
Installed SetCPU and have it so that my phone is under clocked to 245mhz when screen is off.
Turned haptic feedback off
Turned Off Auto-Sync
Manage my running applications with Advanced Task Manager and have it so that it ends apps every 30 minutes.
Flashed the newest Radio
Reconditioned my battery like HTC representatives suggested
Even with all these changes I'm lucky to get 10 hours of battery with moderate use. Far below the 16-20 hours that other users claim to get.
I don't understand why my battery life is so bad. Any tips? Maybe something I did wrong?

Connect to the marketplace for about 20 minutes in total and and never watch youtube videos or surf the web. I spend around 20 minutes a day on the phone at most.

Perform the HTC suggested battery cycling.
Charge until full, unplug, recharge, unplug, recharge, turn off, recharge, turn on, recharge for a few times.
No comment on the battery life as I have no problems but why did you want this phone in the first place if you only text and don't use the internet? I would own a Blackberry or Nokia E71 if I used my phone in that way.

I expected someone to say that, I used the internet heavily for the first few days and saw the horrible battery life so I started limiting how much I went on and this is how much battery I'm getting now. I do use apps sometimes though

I tried that, it worked on the first day but then battery went back to normal the day afterwards
Try running dcpowertop via ADB to see if something is causing a lot of wakes and preventing your phone from sleeping. Also try running Systempanel monitoring to see what is using up the CPU time and draining the battery.
Also, this does nothing unless you are running a custom kernel (You didn't mention if you were, so just sayin'):

But, even so, you should be well above 10hrs battery life with the other changes you made.

He's better off with this deal really, many members have purchased them (including myself) and they perform near as well, or just as well as the OEM battery - but you get 2 of them, AND a charger:

Most batteries above 1500mAh do not even perform close to what they say they should. Check out batteryboss.org for details.

I'll give dcpowertop a try.
I just uninstalled overclockwidget and installed SetCPU instead, the new version has the perflock disabler which should allow me to underclock.
If you are in a sketchy service area, your battery will drain fast.
How much do u use your phone? That's right there the key when other people say ILL GET 16-20 HOURS OF BATTERY LIFE. Yes cause they don use it as much as i do, maybe u use.ur phone hardcore too, texting mms back and forward like no joke. Lots of them. I do over 600 just the morning. So my battery die around 2 then i use my hero battery that i have as back up. Its BS when other ones say that they get crazy amount of battery. Yes it can be but cause they don't use the phone as much, my buddie has a iphone 4 and we tested it against the evo and yes he's better but not crazy better like when i was on 50% left he was on 62-65 % my phone died first he was on 10% left. ...

Ok, so SetCPU does actually work and I have successfully downclocked my phone.
If you send 200 texts per day and do little else, as smart phone is not for you. Get a more basic phone that would give you 3-4 days of heavy usage.

That's very strange especially with how little you use it now to try to get more battery life.
Only other thing I can't think of that's not on your list is disabling Google Talk auto sign-in. Not that I think that will make up the difference you are seeing, but it's something else to try. You seem to be doing everything right, maybe try a clean ROM install?

Im running "bakedsnacks" latest version, try that. Ive been having insane battery life. It already has the undervolting kernel in it. Give it a try, u have nothing to lose. But you have to remember that the Evo is a beast .

Follow the Battery Recalibration instructions in the cyanogenmod wiki.
Doing this, I was at 73% after 26 hours unplugged. Yes, I was using the phone: 20 Text messages, about 20 minutes of pocket empires, 20 minutes of another game, WiFi enabled for most of those hours, and I even ran the "Relax and Sleep" app for half an hour when I went to bed.
DC 3.2.3 with the Balanced profile.

You don't need to turn off all those features to get better battery life.
If you really have trouble, simply downclock the cpu to something like 460 Mhz and you battery life will double.
Then have someone make an undervolted kernel for you, and your battery life will triple.
When you say managing your apps with ATM? Are you using it to kill your processes? You probably don't need to manually or even schedule task killing with the lowmemkiller in DC.
One thing you didn't mention is what your signal strength in the area is. My 3g reception is utter trash in my office, so I have an extra cable to keep it charged. Overall, my phone drops about 1% while idle and I don't have any task management or cpu throttling apps going.
What is the best rom for the Epic that will improve battery life? I have an Evo. My wife has an Epic. Mine will go all day and end up at 45-50%. Hers will end up at 15-20%. I know that 2.2 will make some great changes to the battery life (God I hope so), but what choices do we have now?
Epic Experience with Phoenix kernel gives me a good 14-18 hours with medium usage.
Rims don't change anything really battery related. Kernels are what effect battery life.
Also, you don't need a specific kernel to get amazing battery life. Get these apps
Spare parts
Autostarts
Juicedefender ultimate
Spare parts will tell you what is killing the battery
Autostarts will disable the drm crap on startup
Juicedefender will disable the data and wifi when not needed.
I can get 24 hours on my epic without even trying to conserve battery.

Speed freak and in desperate need of good battery life are polar opposites of each other. Nothing the phone does at this point needs the processor to be clocked any higher than stock and doing so is detrimental to battery life. The phone is plenty speedy using that combo. You might get the occasional hiccup in a menu for a half a second, but it is worth it for the amazing battery life, and it isn't a big deal at all.
yeah i realize they are complete opposite. im just trying to find a good balance between battery life and power. i may just have to sacrifice a little power for battery life then. i will try this combo maybe tomorrow, seeing as though i have homecoming tonight lol.
i get 60 hours + with moderate usuage. andromeda rom which includes andromeda kernal. You do not need spare parts or any task killers. 24 hours is weak battery llife. phone calls is the most extensive battery drain. if i do not make a call i can browse all day and still have 40% left.
This is how you get amazing battery performance.
I have some very VERY helpful hints of great battery life for the Epic 4g. (as i am on hour 26 to 28 and have 20% left with about 1 to 1.5 hours of screen on use.)
First off, use black, or almost black background. Our screens are superAMOLED. This means that if the screen is showing black... those particular black pixels... are simply not on. If you have the home screen black, and have no icons on it, then the status bar is all that is using power... maybe 6 or 8 percent.
Next, Lose the brightness. A few helpful hints on this. 1) uncheck the autobrightness in the display settings 2) turn the brightness down in the display settings 3) If you slide your finger from right to left across the status bar at the top, the screen will dim, if you slide your finger from left to right, it will brighten(this causes accidental brightness 4) cover this light sensor on the right side at the top (I believe) because the phone seems to have a problem always autobrighting even with the uncheck in the settings. This is done best with electrical tape, or perhaps finger nail polish. These things should ensure to always be at minimum brightness
Next, Install Frankenstein Froyo Rom(lightest rom=less cpu usage/blackest rom=less screen battery usage), And Genocide Kernel(undervolted)
Next, install task killer(keeps the rom at optimum efficiency meaning less cpu usage assuming you are killing the apps 3 or 4 times a day) install set cpu(This allows you to limit the cpu clock speed(400mhz is optimal usable and battery settings)
Things to remember, ALWAYS TURN THE SCREEN OFF.
If you pick it up every thirty seconds to see if you have a text, then just sit it down... whats happening now.. The screen is staying on for another 15 seconds probably. DUH!!! bye bye battery!!
TURN OFF THE SCREEN BEFORE YOU SIT THE PHONE DOWN!!!
Turn off gps when not in use.
Turn off wifi when not in use.
Turn off 4g when not in use
Dont use it as an mp3 player.
Dont talk on speaker phone.
Those last few were pretty obvious.. but some people need to be told.
I Hope this helps anyone looking to conserve battery. Follow these steps and i promise 24 hours plus ever time and often as much as 48 hours.
Enjoy
EDIT****
By the way, When you set yourself up with this rom, you are making your phone TWICE as fast... LITERALLY. Hard to believe that a ROM could be twice as fast.
With stock android2.1 this phone gets 800 to 900 in quadrant(benchmark tool/tell how fast your phone REALLY is) Stock android 2.2 quadrant score is a little better scoring as high as 1000.
With this setup, i have gotten as high as 1950 in quadrant. No joke. This is reflected as you cant even tell the phone is clocked down to 400mhz without heavy apps and REALLY paying attention.
I just want to know what I can do to improve my battery on CM7 nightly 32. I'm at 21 hours now and almost dead. Yet I see people get stuff like 2 days and 10 hours... I have tasker and the only profile I have is when the screen goes off it turns mobile data off (not sure If it works so I also use apndroid). I NEVER use wifi, bluetooth, or high brightness. I do however have gps on so in case I lose my phone is lost or stolen I can track it. So there's no way I'm disabling that. I have tried juice defender but figured since it can't effectively disable data for 2.3.3 I saw no point in the app. Any tips?

21 hours on moderate use is great battery life. 12 hours is usually the measuring stick for smartphones, less is bad, greater is good.
Don't know who you saw getting two days plus, but they are either not touching their phone or have an extended battery.
Sent from my T-Mobile G2
Best way to extend battery life is to get an extended or high capacity battery. I just got the Mugen Power pack, not the chunky one, and im in the process of breaking it in.
On my stock battery i was getting about 17hrs of moderate use. Almost no talk but alot of texting, engadget and youtube mostly on wifi with gps always on. That might give you an idea, plus, there are countless battery related threads on here.
Will post back in afew days after my Mugen has cycled afew times.

I have 4 stock replacement batterys and never plug my phone in to the charger. When my phone is at about 5% i just take one out and pop the next one in and charge them in the wall... I know its not the answer you want but I never have a problem with battery life lol
I would agree that 21 hours is great battery life on this phone. I can get a week of battery life on my phone if I put it in airplane mode and stick it in my desk drawer =P
Not sure how big of an impact the tasker profile has. Unless your screen is off for long periods of time I would think that it might harm the battery life because every time you touch the device, it has to 'search' and connect to the tower again.
You can try running the phone at the stock CPU speed to see if that has an improvement on your battery life. I currently run the same 1017/245 as you with a screen off profile set at 245/245.
For me, as long as I can make it through a day's use, the battery life is fine. With moderate use I can go about 15-18 hours and heavy use I'm at around 12. The car charger in those cases is a life saver.
Bottom line is, battery life really depends on your usage habits. Those people getting days out of their phones likely aren't using them very much...
well i have setcpu set at 806 max and 245 min. screen off is at 245/245 and on powersave governor. other then that its on ondemand. i also have profile set to reduce the CPU based on battery. I have it set to <101% its at 806/245 , <41% its at 768/245 and less then 25 is 368/245. i realize that these are low speed but i hardly ever get lag and i use it for everything, music, video, youtube, internet, twitter, facebook, xda , and a here and there gmail. i guess if im getting exceptional battery life... anyone want some tips?
I find the more variation I put into profiles on setcpu, the worse my battery life gets. Theory - it is constantly watching and making changes based on your CPU needs and battery. So I have mine set to 1113-1113 performance, 245-245 powersave screen off, 245-245 powersave 45degrees+ and for your mobile data, try just having a widget to turn it on and off as you need it. You probably don't need it on everytime you turn on your screen do you?

The apndroid widget eventually gets out of sync with on/off with the data... I think its gingerbread. Most apps can't effectively turn the radio off. I hope they make one soon!

I find the stock battery to be not that great. I bought the Chichi batteries way back in October (when they were still considered cheap) and theyve been great. I havent really done any new tests since October, but back then (before I had a data plan) I was getting atleast a day and more (from 100% to dead) with moderate usage.
I'd look for a high capacity battery, though they seem to be expensive now.

Ill post a battery success story...sounds nerdy lol. And i live at my own home with my own family lol.
My mothers g2 is rooted and running cm7 nightly 29 or 30, I installed it last week. I asked her today for the first time how the battery was after a week. She is using an aftermarket 1800mah battery, wifi only at home, she was almost at 32 hours and had 39% battery left!!!!
Not sure of all settings but i put it on 1113mhz, on demand with min 368, autobacklight, wifi only at home, bluetooth is always connected and on. Talk is about 70% of her usage overall. 4 gmail accounts. I did not install set cpu at all. I even stopped it on my phone because it didnt help me one bit.
Not too shabby. I was at 57% with some texting but a lot of gps usage for latitude and wifi always on even when not at home.
sent from the rooty tooty fresh and fruity cm7 nighly powered G2
here is what i get out of a day (battery consumption for specific tasks are mentioned in percentages measured using juiceplotter)
wifi on constantly
display set to 24% brightness
background sync enabled (google, weather 6hrs, whatsapp and facebook once a day)
45 min video (rockplayer no h/w decoding) 15%
1 hr browsing+chat 15%
30 min calls 6%
20 min music+chat 5%
20 min general usage 5%
1 hr flash streaming 15%
24 hrs standby 24% (@ 1% for every hr of standby)
15% battery remaining after 24 hrs i.e. low battery warning.
i disabled the use wireless network option under locations and always on mobile data
and get much better battery life, also i use wifi constantly when available (which is 90% of the time), it is much better for battery life than using 3g or gprs/edge.
pretty amazing battery life IMO i am very happy.
So i have cycled my Mugen 1800mA battery acouple times. on average, i'm able to get about 27hrs of heavy use. Here are some settings as a baseline:
Always on Data
Wifi always on
Auto brightness
1GHz clock speed
massive amounts of text use
massive amounts of screen on time
will report back in afew days time after some more cycles.

Same here..............................first 10% dies quick, seems to settle sa little after thay
ddi you check any background app that could be running for updates (timescape, weather...etc), these apps tend to cosume battery for updates even phone is in idle
if you are not sure which one it is try turning off the traffic and see if the battery still drains crazy, if it behaves normal I would say one or more of your apps running in background is the cause
no even i got same problem since i installed wolf's 3.5 and later my battery drains very fast !!! was using the wolf;s v3 before battery was very gud ... even all apps which m running now used to run before !!
Try wipe battery stats then fully charged it and calibrate it.

It could take a few days for your battery to settle down after you have done a callibration.
Can you get cpu spy from the market and see if you phone is going into deep sleep, there could be some app that is using up your battery
the first 10% of the battery dies very fast and it's some kind of "trickle charge" to top off the battery. it settles down to a steady depletion after 89%.
3G eats all your battery, also check if your CPU maintains high clock speed all or not.
Yeah. As other have stated, download CPU Spy and leave you phone in standby (and not charging) for a while. Then check CPU Spy and make sure the phone is going into "Deep Sleep", as well as running at lower than 998 MHz. You may have to refresh within CPU Spy (via the menu button).
Also, if you're not connected to a wifi network, turn off WiFi. Otherwise the phone will search for a network regularly, wasting battery power.
my personal suggestions was, try to put brightness below around 50 or 60 percents.. its good enough even under bright places.. or you can try to raise the refresh frequency for those application you using such as beautiful widget / facebook update interval.. and try turn off those gps/wifi or any data traffic that running if you are not using it.. lastly also put the brightness to 0, if you are idle from using the phone or just to listen on songs, use earphone if possible.. thats what i do, its probably messy but its work quite well
Okay, THANKS. I'll try all these and report back.
Once again, Thanks y'all.
Ok it depends on alot of stuff
1.your baseband
2. Flash 2.1 wiped everything in xrecovery then flash any desired rom.
3.turn off backgroundd and auto sync
4.gps turn it off when not using it
5. Data turn it off also
6. Put brightness to 50%

I actually had a dramatic improved battery life from v006 to V3.5. Then even longer battery life on V3.6. Before, my phone runs out of battery after one, two hours of gaming. Now I can play for four hours.
Eight hours of standby without wifi, data still took around eight percent. mine doesn't have the 400 hours sony claims to have either.

My battery life dropped after installing FPS UNCAP 54. Dramatically.
It's stock, rooted ROM.
It's counting downwards like a counter on a gas station!
From 100% to 1% in cca. 1 hour.
I find that GPS is the biggest drainer on battery so if you use that a lot that might be the problem. Also make it so your phone is only using 2G when you aren't actively using your phone (aka idling in your pocket) you might have slower synching but it isn't like you are using your phone during this time anyway.

Actually, that's good, it'd mean there is no-brainer task eating your juice in the background
Mostly there're three main thing to check out, some of these were mentioned. If you read it and feel it's a little bit too hard, jump to the end.
(1) Deep Sleep, check it through CPU Spy or SetCPU, if the phone idle, it should go to deep sleep
(2) App usage, since 2.3 arrive, it's much harder to check. Try "SystemPanel (Lite)"
In most case, it'd be these 2.
(3) Another one is to check the memory usage vs. minfree, the most essential one is "AutoKiller Memory Optimizer".... probably your custom ROM might have optimized these value already. But sometime the problem is that your normal usage has overloaded the minfree level, (too much background app, too much widget, too much sync) which cause the OS to shutdown some task while it'd be re-opened a few second afterward, this cause a stupid battery drainer loop.
Use AutoKiller Memory Optimizer, it'll show u 6 slots with amount of free memory, the trick is the free memory shouldn't be close to the forth slot.
HOWEVER, if this sound too complicated for you, I suggest first try to remove the widget one-by-one, uninstall some background apps to see if it gets better.
You could blame ROM, but the problem is not the ROM itself, the devs just try to optimize their ROMs for most users, some essential ROMs provide stability without many tweaks, meaning that you could just put 20 widgets without much troubles. An optimized ROM is a trade-off between multi-task and performance. That's why it's not work on some people.
Maybe you have an app keeping your phone awake, hence x10's gb runs at 998 mhz all the time, that could drain the s**t out of your battery, download setcpu from market, i lose 1% every 1 or 2 hours, im on stock 2.3 pre rooted by doomlord

I saw a similar topic in the atrix section and it looks very useful, so I searched the samsung forum but found nothing. Therefore I created this. Feel free to post your CM10 based rom battery life.
This is more for trouble shooting and sharing tips and tricks to extend the CM10 battery life. Also post some screenshots to show us your battery life, one of tour screen on time and one for your overall usage
Thebyani ROM 4.1.1 very good battery life.

Testing RRemix
I get a drain of 4-5% per hour on CM10 which isn't normal. According to BBS I don't see any excessive wakelocks, also battery stats in settings shows phone sleeping.
I tried a lot of different things to see if the drain reduces. Finally when i changed 3G to 2G the drain reduced.
I know 3G consumes more battery than 2G, but this drain was excessive and nothing like I saw on Stock or CM9 ROM's.
I'm using PA 1.98 and Siyah 4.0.1. I feel this is a very good combination in terms of battery life and performance.
On a full charge, I easily get around 20hrs on medium-heavy usage. I used Lux AB to control brightness and VC just for reference to check on deepsleep and cpu states. I also used battery widget reborn beta for its cool stats and auto flight mode control. Disabled all haptic feedback and vibration alerts cos I could just use a low-volume profile. Disabled hardware keys backlight(if i can find the home button in the dark, no prob finding the rest)
Edit: I use stock 1650mah battery
In extweaks, I set battery profile with the following settings:

I have very good battery life with version 2.7.0 and CM10, but USB Mass storage isn't working. Also you can try newest Siyah.

Yes, I experience the same. 3G draines the battery and much more than on any other ROM I ever used.
My battery is no better or worse that on other roms, i loose about 15% of battery an hour with half an hour use or so. Any screenshots anyone? Or tips, did anything improve your battery??
i using CM10 ,the battery consumption still bad compared to stock rom ICS..so,no different to me,LOL

I get that in every ROM, even stock. I get half decent battery life now, deleted battery stats this morning so gona see how it goes tomorrow. It almost got me through the day though. I'm using extweaks to under volt my phone

A drain of 8-10% per hour if you actively use is fine. But while sleeping my usual drain on stock /CM9 is about 1-2% per hour.
I think due to all the hacks that are required currently to get CM10 working with ICS closed binaries we have this battery issue.IF it was
an app BBS would have shown, if my phone had deep sleep issues, cpu spy should have shown but I don't get anything in either of these.
CM10 on Galaxy S2
I'm running the latest CM10 nightly build (20120906) for my Galaxy S2.
The ROM works blazingly fast and I haven't had any bugs as of yet :victory:
The battery life is quite poor however, I get around 11 hours from full battery to nearly dead with moderate-light usage.
Today I used Google Navigate with GPS and 3G for around 15 minutes and it chewed through around 15% in just 15 minutes :crying:
I really hope they fix the battery life as its the only thing holding this ROM back.
This was my rom drain on standby with cm10 pretty good in my opinion

That's pretty awesome. Care to share the build and if you did something else (other kernel, settings, anything)?
my phone has battery problem with CM10 too
battery dead 2x faster than CM9 Rom
specially when use Wifi or GPS
i never had my phone for more than 20 hour
I am using CM10 nightly 20121017. I have switched to CM10 nightly builds since two weeks. Before I was on stock 4.0.3 Greek Vodafone. Also I have tried a lot of custom ROMs.
In conclusion: with 3G on, WiFi keep alive, gmail, push exchange mail and all other notifications off (eg Facebook), all touch vibrations off, from 8am that I unplug the phone, it lasts max until 5pm. And this is Almost the same with all roms. :thumbdown:
This is a smartphone and in order to operate as a smartphone of consumes a lot of energy! I can get a Nokia 6310 to have just a phone that lasts for a week...
My opinion is that someone must produce better batteries!

I hardly get a day of battery life. The most efficient battery saving technique which I realised was to put your phone into airplane mode when not in any use. I put my phone to airplane mode while I am asleep or I am attending classes. Amazing battery saving technique.
Other thing we can do is to use a cm10 version of rom with the memory leak issue fixed. If its not, you might even need to charge your phone even twice a day.
Disable 3G(use 2g only mode) when not using the web. 3g sucks a hell lot of battery.
