[Q] Help with battery usage / drain, how to increase battery life

Ive searched around and this seems to be a common issue, I tried the factory reset even the htc battery conditioning where you charge fully turn off then another hour back on for 2min off again and charge for another hour with no positive results, I read online some ppl are getting -1/-2 mah an hour I have never seen single digit in my phone.
I included screenshots of my battery drain even adjusted the app to read 1500mah, anything else i missed in settings? Also went into phone information in the Tests menu set it to auto instead of GSM, also with SetCPU I tried underclocking with little change to mah usage, running out of ideas...
Currently its rooted with GingerBreak, and CM7 with #48 nightly installed, any help would definitely be appreciated.

How many hours is your phone lasting on a single charge?

Lately between 5-7hrs one had about 8 and half hours a handful of times

it's true that if you constantly use the phone nonstop like watching youtube, browsing, playing games, etc. the battery won't last longer than 4 hours without getting an extended battery, heck just using moderateley the battery will be about 50% by the end of an 8 hour workshift, but what I found that will extend the battery life with moderate use are these...
1. Turn of wifi, bluetooth, gps, sync. (contrary to what ppl say on this forum I find that wifi eats way more battery than being on 4G)
2 Disable background data. (The only thing I actually need background data checked is to use the android market or maps when I need to, with it off it's a huge battery saver)
3 In settings choose to use only 2G (This will increase battery life 4x and Tmobile 2G is pretty fast, just like 3G)
4 Download Opera Mini (Since you'll be using 2G to save battery you'll want to surf the web with a browser that is super fast using slow connections, and Opera mini is second to none. You can always turn on 4G when you want to have fast video streaming but then you eat alot of battery again.)
5. Install Auto Airplane Mode (you can turn auto airplane mode on when you're not gonna be expecting calls such as at work or when you don't want to be disturbed, hell, if you just want to save as much battery as possible. Since Auto airplane mode disables the radio and data completey which is the number 1 cause of battery bleed with it on from a full charge unplugged you'll still have a 100% when you wake up your phone after a day.)
6 Install juice defender (free is fine)
7 Don't use Lookout Antivirus (I've found Lookout drains the battery quick, if you want an antivirus that doesn't eat the battery try AVG. I prefer AVG because I notice it does not drain my battery like Lookout.)
This has made my phone last more than a day on stock battery with moderate to light use. If I think of more tweaks I'll add later

This is ridiculous. If you have to turn off all those features, then don't even bother getting a smartphone.
My tips are:
1- Set brightness to auto.
2- Avoid Skype and other apps that usually appear as On going on the status bar.
3- Get rid of any task killer. They actually make the battery life worse. Don't worry about tasks running in the background, the OS takes care of them. If you wanna quit an app, try to look for a quit button by pressing the settings button when the app is on the foreground. Otherwise, just press the back button below the screen until you get back to the home screen (for some reason this seems more efficient than just pressing the home button.)
4- If you don't use IMs, get juice defender and set it to disable data when screen is off. It will turn data automatically on once you turn the screen on by pressing the lock button on the top of your device. Note that this is different compared to auto airplane mode, with Juice Defender you can still receive phone calls and text messages when the screen is off.
Last but not least, consider purchasing an extra battery and/or car charger.
Mine usually lasts for about 12 hours with moderate to high use. Almost all smartphones have short battery life if used heavily.

Yea that's awful. Do you by chance have your brightness set extremely high? And how is the cell coverage where you usually use your phone?

I think all of the advice above is valid and will save your battery. The question is to what extreme do you want to go? I tend to agree with donatello88 that there comes a point when you get so paranoid about battery life that you may as well not have a smartphone because you've turned off most of its features.
Get rid of any task killers, battery monitors, etc. They are simply churning thru clock cycles and that uses more battery. Set email, Facebook, etc to check for updates less frequently. Either use auto brightness or manually set your brightness to about 25-30%. That should b bright enough for everyday use unless your in bright sunlight a lot. Use juice defender if you like. And be wary of antivirus apps. I've heard some can suck ur battery dry.
If you do those simple things and are still getting only 5-6 hours then I'd be taking it back to T-Mobile ... unless of course you're on your phone without ceasing. In that case, what can you expect? Lol

Ok with the tips I just mentioned above, I got a chance to put it to real world test. I caught the bus to my son's grad ceremony and reached there at 4pm ceremony didn't start till 6pm so those 2 hours just surfing the web reading articles and forums I was down to 90% battery. Didn't know how long the ceremony was gonna be so called my sister on video chat using tango and spoke to her for about 20 minutes. Did some more browsing using opera mini set to only use 2g for another 2 hours, my don came out, I took some pics and video of him turned on 4g to video chat again with my duster for about 5 minutes, and after 4 non stop hours of consecutive use with screen on, I'm now at 71% battery life. I'm at the bus stop now on my 12 mile commute home and I'm confident the battery will give me more entertainment until I get home. Awesome! You don't have to believe me, just try out my tweaks and you'll be amazed.

Everyone thanks for all of the help and tips, today was the first day I saw 10hrs+(included screenshots), I had my screen on auto and after some reading saw that with CM7 it doesnt work well so I have changed it down to 20-40% depending on where I am, turned off background/auto sync only turn it on when I need it and uninstalled the app killer I was using also changed a few of the SetCPU profiles.
Im not really a heavy user just wondering if having 3email accounts set to update every hour would be a battery drain too? I mostly text/email during the day and talk about 1-2hrs depending how busy I am at work.
Again I thank everyone for pointing me in the right direction...unfortunately at home I have 1bar to none for service so I do depend on Wifi calling which im sure drains more juice, also at work since it in a high rise not too much cell signal so wifi on most of the day...

Hello risho,
I was having the same kind of battery life... After 3 months of research, I collected all valuable tips.
"Valuable tips" means: tips that do not need constant involvement from your side (you don't need to go switch on/off things, etc..) and also that leave you with a very functional phone (you have location when you need it, you have e-mails flowing regularly enough, etc...)!
With these tips, I am now lasting from 6am to 11pm and at 11pm, remaining battery is 10% at least!
Go and check my thread: [Ultimate GUIDE] Increase your battery life on Android!
Enjoy!

Juice defender=placebo effect?

So ever since I first bought the G2x, I've always had juice defender a part of it. Now having done a factory reset, since May (when I got the phone) and not installing juice defender, it seems that I get the same if not better battery life without juice defender installed. Could juice defender just be adding to the battery drainage also?

Yea, I am in the same camp. Juice Defender really has done nothing way too much tweaking it. I have to say its like all of the purge from memory apps...you mileage might vary, but for me they aren't really helpful.

It seems to me that juice defender might be good for over-night, or for situations when I'm not going to be checking my phone for hours. Otherwise, the radio keeps getting turned on and off...on and off...everytime I wake the screen to text or something...that's in addition, of course, to the regularly scheduled times that it does it on its own.
But then again, instead of having it running all the time, I could probably get the same effect if I just went to airplane mode overnight.
Interesting point, OP...and gave me something to think about.

I'm gonna test that today, yesterday I got 15 hours with it on and set CPU profiles today ill turn off juice defender ultimate, ill keep u guys updated.

Yeah, I tested this week. Ifound no noticeable impact of juice except maybe overnight. During the day, and no impact, and perhaps even a negative impact.

I just manually toggle data off at night anyway.

There is really no reason to ever use juice defender when Tasker exists. It can do everything JD does and SO much more.
After testing pretty much every setting I could think of, the only things that made a significant difference is disabling data and GPS. I set up a screen off = data off, screen on = data on set and battery life WAS improved. However, I use Google Voice for all my texting, so I had to have some data, so I tried the same thing but reducing to just 2g and no improvement was noticed.
Keeping GPS off permanently but allowing it to run specifically on applications that need it helps too. Note that this is not possible on gingerbread except for CM7 and ROMs built off of CM's source. I imagine toggling bluetooth and/or WiFi would influence things too, but I never use either. No other setting resulted in a significant improvement in battery life.
Note that during all of these tests, I kept screen brightness to 18%, toggling to 25% when in direct sunlight and 0% in the dark. As for airplane mode at night; I plug the phone in at night and unplug when I wake up so this is a nonissue for me but AM is the best you will ever see your battery life without using things that require root.
And, of course, underclocking to minimum when screen is off improves more than everything else combined. Kernels and clock speeds matter far more than things like GPS or data connection.

Well I'm through testing today I got 11hrs and 18 min without juice defender compared to 15hr with it yesterday, and I used my phone less today, so juice defender gave me about 4 more hours, tomorrow I'm gonna use juice defender and 2g.

I don't use any battery management apps, I do use android assistant to close apps every once in a while

Yesterday with juicedefender set CPU profiles and 2g I got 20hrs battery life.

Oddly enough, the free version seemed to work better that the paid version. A lot of the time wifi and 4G will stay on even when not using the phone, and I have to manually turn off/on wifi depending on the situation. As stated, it does help when not using your phone for a while, but I'm no pro at it or anything, could be the settings.

Juice Defender on Sensation yes or no?

I used Juice Defender on my Vibrant and it seemed to help quite a bit. However, on the Sensation, because it is running gingerbread, I have read mixed reviews. Some say it helps, some say it doesn't. I'd like to know your experience with this or other batter saving apps!

If nothing, it starts/stops mobile data when you turn the screen on/off. That on its own is a huge battery saver. It also turns wifi off when it's out of range, and mobile data off when you have wifi.
These things obviously increase battery life, no question about it. Of course, if you never have mobile data on, and don't want to have it on, there is no point to having juice defender

I find that it perpetually signs me out of Gtalk

Hmm. I was debating whether to get the elite version on the market as it seems to have a lot of extra features. I didn't know there were mixed reviews with gingerbread. Thanks.

I get an issue with juice defender where after I've turned the screen back on there is still not mobile internet connection.
I have to manually put the phone into flight mode and back to get a connection, and sometimes even need to reboot.
I got pretty much the same advantage as JD without the hassle by just enabling 'Power Efficiency' in the 'Power' menu in the settings. It turns off background data like JD and allowed me to go a full day with fairly high usage and still have 30% at 8pm.
N.B. - Having background data off means your widgets and mail won't sync as often so I put a 'Sync all' widget on one of my homescreens so that when I wanted an update then I could pull everything down at once.
Hope this helps

I've been using juice defender but I think I will try your suggestion for a couple days and see if it makes a difference. Thanks!

If you check the "always allow mobile internet" button in your wireless settings will give you a good compromise between stock and how juice defender constantly kills the data connection. That setting for me is good for an extra 20-25% a day. Only thing I notice differently is emails may take a minute or two to arrive and Gtalk is signed out when I don't have the phone active.

Juice defender will just manage your apps, settings to save battery.. just to regulate your battery..

I am using Juice defender and it's saying 1.61x now, the battery last about 3 days(I am not a heavy user) but before that it didn't so I found it to be quite helpful

yeh me too... from 8 hours to 10 hours with juice defender..

Extreme measures for better battery life

I finally decided I would take some extreme measures to aide the BL of my Androids. I have an HTC Inspire and HTC HD2 with Nexus S Android. The HD2 isn't all that bad...much better BL than the Inspire, but I wanted to apply this measure to both phones. Will it help? Only time will tell.
I started by removing all screen widgets. Then I sorted the screen icons so that a minimum of homescreens were needed...got it down to 2 homescreens. Then I deleted all widgets without apps not able to be opened through an icon. Then I went into Applications manager and cleared and stopped all non-used apps and services. I also deleted all duplicate services such as OEM email accounts and their associated syncing....using add-in apps for them. (example: built-in apps and widgets like Facebook, Twitter are uninstalled or disabled and am using another combining app like Seesmic. Same goes for the email app)
What I currently have is an Android iPhone. I'm using only icons on the 2 homescreens. And this makes me understand why Apple refuses to use widgets and stick with icons...to preserve BL. I hope this will improve the BL of my Androids because it is purely horrendous. And it is horrendous with all Androids I've tried and used.
Until the recently announced battery tech breakthrough is made available, this might have to be how Android is used from now on. But I doubt these extreme measures will actually help.

What is the difference between a widget and an application?

An application is a single, whole program package that is loaded into the phone. Examples would be Tapatalk, the default Calculator, and Angry Birds.
An application can have one or more widgets in it -- a widget is an interactive thing you can place on the home screen. It can give you information, and you can tap on it to change what it says. A good example of that would be Beautiful Widgets, or the little Android guy that tells you about how to use your new phone.

@Marty, how long was your battery lasting prior to the "Extreme Makeover"? Mine currently will last me 2 days. Admittedly, I've not loaded a lot of stuff on the phone yet, and I have the power saver mode start at 70%...but I only need to recharge every other day.

My desire lasts around 2 days with moderate usage. But on a good day (read: many boring moments), it's completely depleted by the end of the day. My biggest battery drainer is whatsapp, if I uninstall the app my battery will last a LOT longer.
If i really need my phone to last for a long time (when Im on a big trip or on a festival) I always use JuiceDefender with a very strict setting. This is a big help, but not for everyday use

whats the point? Where ever you sleep you have access to a plug/usb w/e so whats the big deal ? how hard is it to charge the phone every night? even thought my galaxy s2 hold battery for 40hrs+ i never need that :|

Ive dont the same thing, I also found some build prop and init.d tweaks that improve battery life.
my brightness is always at minimum, i have only one widget,
My battery could last two days BUT i use my phone a lot. like its on for 7 hours with 4.5 hrs screen on.

Hilarious.

ther have been many apps and disucssions on BL. heres some common tips.
screen to lowest brightness possible setting. background data always off unless using market. disable -use wireless networks- options, no gps, no location. also turn off *back up my data*. wifi always off not in use. screeen timeout no more than 2 minutes. turn off animations and transitions. setcpu with moderate settings (if you can do a screen off profile it will be beneficial but beware Sleep of Death.) no live wallpapers. minimum widgets or none. minimum homescreens or 1. startup manger. adfree. location cache app. and battery calibration to get the most juice.

the issues seems to be alot with hardware the Htc inspire and HD2 have 1250 Mah Batteries , which are very small.

If some people are just like me... I can kill at 1800mah battery in 5 hours even at full charge...
I do everything on my smartphone. So anything to save the battery is a good way.
I have the Galaxsy S II and I've managed to drain the battery in 6hours of usage and since I'm not near a power source most of the time then yeah I need all the juice....
I don't sit in an office or am near a power source 80% of the time. I usually carry 2 spare batteries with me and a charger for them just in case.
Cheers! (Extreme power user).

Whats the point??
Here is my daily usage :
Alarm goes off at 6:30am (phone gets unplugged)
Blahblah (at work) reply to emails and messages throughout the day, on twitter A LOT (plume premium)
2 calls approx 30 mins each
Play some games at break and lunchtime (Drag racing KILLS my battery, a bit of plants vs zombies, grave defence HD and maybe some pinball deluxe)
more emails and twitter
another 20min call
a little more gaming while im waiting on customers (1hr or so??)
6pm go home for 6:30pm
BAM! battery is at 10-20% and i need to plug it in again.
this is a typical 12hr day for me and im sure others have longer days and i would appreciate not having to rush home (sometimes) if im expecting a call.
so as far as im concerned anything which will save some precious battery on my devices is appreciated.
btw i have reduced my homescreens to 3 and only have 2 widgets running and that has made a great difference to my battery life (esp. on the DHD)

Basically kill factory and carrier bloatware and you are getting better.
One thing I was amazed about was the eBook reader that comes with our Galaxy Tabs, and suppose others too.. it always working even if you dont have or use it.
And remember, the screen is what takes most out of your BL, always. Lower brightness? Get a better ROM with no bloatware and maybe undervolt the screen.
Homescreens dont change a bit. Widgets do, if they update a lot.. more than that notification stuff do. Like if you use a antivirus or antisomething, just check of notifications.. check of any unneeded notifications.
Vibration theorically is what consumes the most.. but since its not as used as the screen, you dont even compare them. But every little bit helps. Check off keyboard clicks and hepatic feedback - vibrations.
Wifi, bluetooth, data... don't actually consume much.. actually it's better if you leave a service stable on, than keep sleeping and switching it. So leave wifi always on, no sleep policy. But when you go out turn it of so it doesnt keep scanning all the time (unless you want to ).
Just like any PC, the more you install.... Just check what you got going on, learn how to check processes and services that keep on all the time, and there are some utils to help stop some crap from starting up. I use ROM Toolbox and Autostarts.. some stuff get activated just because you plug you device to charge!
DONT use task killers... dont let anything like that keep running... and no, GMail push notifications wont use any batt. Maybe pop/imap emails always pollling will use some.. but probably nothing compared to the examples above.
Cheers for my 2 cents.
EDIT: and after Xmas, remove those animated wallpapers!

Is Juice Defender a task killer? Not really sure what is it but I've been wondering about that.
Juice Defender Ultimate has been giving me about a 1/3 more time with screen on max. Why is my screen on max, because I was trying to drain the phone. It's on about 40% now which is still pretty bright. I wouldn't be mad to get more life but I think 20+ hrs with moderate use isn't bad. I think the most I did was search the net about 4 hours total. But I was also, customizing, so it the screen was lit for a while.
This is a TMO GSII I'm talking about.

There are a ton of things you can do, but the truth of it all is that our 3G/4G radios pull so hard they drain the battery, which is why you were on the right track when you disable active since, Facebook and Twitter.
The main two things I do, is
1. add a widget for turning off 3G or 4G (If its in your area).
2. Installed Startup Manager ( it disables startup programs in the unseen background, (my phone is rooted)).
by doing these two things I am able to get 17hrs+ on a standard HTC EVO 4G battery. Keep in mind the more you use the Internet the more it will drain your battery. So I only turn the internet connection on when I need it or the app needs it.
*I also only use one screen and remove unnecessary widgets but I find that doesn't help the battery life all that much, (my personal Preference)
*When I or my sons game on my phone I put it on Airplane more which turns off all Radios including the Phone (call/text)
*Drawback to turning 3G off, you have to wait a few second for the internet to come back on and MMS won't download through your messenger unless have it one.
I've been off the charge for 8hrs and my battery life is still at 65%
Sorry to be long winded but if I know anything its battery life

Completely agree. What's the point. Either you don't use your phone for ANYTHING, and watch the battery last for 2 weeks (literally), or you use it so heavily that it lasts only 2 hours....
I was sick recently, and as such couldn't use my phone (I couldn't open my eyes without getting dizzy, and even closed.... still was). Suddenly my HTC Inspire 4G used only 20% of the battery in 10 hours. The previous day, heavy mail, "friendstream" (HTC's facebook/twitter/etc app/widget), listening to music (well, audiobooks) for about 8 hours, and I had only 20% left. And i've found that overclocking the phone to 1.3GHz helps more than any other tweak.
Don't get me wrong, I'm obsessive about using my phone *and* getting awesome battery life out of it. But the ONLY way to true "maximize" your battery life is to *minimize* your usage. But then you might as well buy a feature phone.
And I know a few people with iPhones. a 3GS and a 4 and a 4S. They don't get any better battery life than I do. Heck, they get worse. Even under the same type of usage.
For me, the problem isn't the usage, isn't what's running, or what's loaded (but it does help/hurt). The problem is that battery technology has NOT kept up with consumer needs, or IT development. Your battery is dying as soon as it leaves the factory. Your battery is dying every time you change it. Especially when it gets hot. your battery dies faster when it's cold outside. We need better energy storage medium. Period.

Buy the biggest battery I can find on eBay....
Use the fsck out of my phone all day and have plenty of battery left.
Problem solved.

<<<< What he said

I don't think the use of WiFi could be overstated.
On my Skyrocket, leaving Wifi on (indoors), it'll sip about 1% every hour. I go out and have 4G LTE on, it drinks up about 3% every hour.
Minimizing widgets also helps. I saw noticeably better battery after removing my facebook and Latitude widgets.
The screen also sucks up the most battery. Turn it off on every occasion. Just turning it off instead of letting it shut off by itself has made a difference for me.

Battery technology has kept up with usage. However, battery size in relation to the power draw, has not.
Compare the size of the back cover on your phone, with the size of the battery. Why is the battery this tiny little 2" square, when the phone is 5" tall and 2.5" wide? Why aren't batteries the same height/width as the phone? Why isn't the battery the same size as the back cover? Why aren't phone manufacturers optimising the size of the battery (meaning, making it as big as possible)?
It would be so nice if phone manufacturers would stop with this stupid "race to the thinnest" crap, and started:
- releasing phones that are actually comfortable to hold like a phone
- releasing phones with batteries larger than a pack of matches
your battery dies faster when it's cold outside.

Actually, keeping a battery cool makes it last longer, not drain faster.

[Q] Horrible battery life on infuse

Can someone please help me with my horrible battery life on my infuse? I cant make it a whole day on my phone. I don't play games on it at all during the day because I work. The only thing I do is make calls and text. I had 100% battery this morning at 6:00am and it is now 1:30pm and I am down to 12%. I am running the latest version of catyrom on my phone and it was supposed to increase the battery life. My phone is less than a year old (probably only 6 months old if that) so the battery on it should not be shot. Any help would be awesome!
THANKS!

Should not be like that. All the uckl2 base ROM have very good battery life.
Try a reflash. I would go into cwm, wipe data, wrote cache, wipe dalvik, fix permission, go to mount, wipe system, data and cache. Re flash ...i would try Another uckl2 base ROM then go back to caty if battery seems better

Buy Juicedefender Ultimate, set it up whichever way works for you. I couldn't tell you about Catyrom and the JD AOSP helper compatibility.
Buy and set up SetCPU to downclock your CPU when your screen is off, and when your phone's charge goes under a certain amount. Change your governor to conservative, ondemand, or smartass. Those will help. You could try undervolting, but be wary of doing it too much.
Look at your battery useage history and work out your app issues from there.
A faster microSD card wouldn't hurt, class 4, 6, or 10 would be better than a class 2, if you're even using a microSD card. Faster read/write means less time reading/writing.
If you need even more power, you could always go to 2G networks if Catyrom allows you to use them. From my experience, it will interfere with speakers on other devices. I have ~8 pairs of speakers in my office, and the interference drives all my co-workers nuts.
And you could always carry a spare battery, which isn't the best of options, but it's a sure fire way to go on
Reduce the number of widgets you use, reduce the number of screens you have, remove redundancy in your apps, and turn off live wallpapers.
Turn off auto brightness, and set it down to lowest valuable that is useable, then bump it up just a bit more. Then set your timeout to something conservative such as 15 or 30seconds or 1 minute.

Thanks! I downloaded juicedefender and setcpu both. I had seen juicedefender in the market but was a little questionable about what it does. but I will see what and how good it does tomorrow. I have my phone charging right now so I will upload a pic of my battery life tomorrow around 3 so we can see how my phone is doing. When I looked at the battery usage when I plugged in my phone it was on for 7h 34m 24s on battery and when I plugged it in I had 6% battery. I really hope that this works. like I said all I do is text and call during the day.
Thanks again!

JuiceDefender, to put it shortly, will kill your data connection/wifi/gps automatically and will enable them again on a schedule.
Those won't interfere with your texting or calling, but it will interfere slightly with your MMS. You'll have to wait for data to be re-enabled to download pictures/videos.
You can set up a schedule for work to be on a more frequent basis than the one when you're not at work, and once you set the battery threshold and the "ignore on low battery" function, it will stop all schedules once the battery reaches that point.
It will re-enable data/wifi when you turn your screen on so you can use it.
That's about most of what it does and it does work very well.
If you'd like, you can get cheap spare batteries from ebay. They mostly ship from China so they take up to a month to get to you, but they're very inexpensive. I just got my 2200 mAh battery (it fits just like the stock one) and it's not even broken in yet. It's 2 PM where I am and I unplugged my phone at ~8. I'm still above 65%. I don't tend to have very restricted battery use like some folks, but I do look for ways to reduce the battery waste. Most of my stuff works when the phone is in idle/deep sleep. I haven't done much of anything today with the exception of a very few calls and a few texts, a little surfing, and I downloaded a CM7 update from the CM7 port's thread.
When it's been broken in it should do better. CM7 isn't as battery friendly as some other ROMs but I like it very much so far. I have been furiously debating whether or not to move to Zeus ROM, as it seems like the big boy's Infuse ROM right now but I can't tuck away CM7 just yet
EDIT: Another, probably very minor, battery saver would be to download and install Adfree. It reroutes all outbound requests for advertisements to the device itself, so those don't download data and you don't see ads. Instead of them possibly keeping your scheduled data connection on for longer while they download (or pumping up your data useage), they never go outbound because they don't require internet access once checked against the HOSTS file.
Also don't forget to do what qkster advised. Bad flashes do happen, and you could have just had a bad flash.

Bassman--What does about phone say is eating the battery?

I have never gotten what I thought was decent battery life out of this phone... I work as a field tech so this phone is my office... Serendipity gave me the best battery life of any rom I've tried and I've tried several.
When I first got it I used Infused rom I would average 3 to 4 batteries a day. When I went GB roms that dropped drastically to 1-2... Serendipity would get me through the work day (8-10hrs) and home w/ a little to spare. Lately I have been bouncing back and forth between caty and zeus averaging 2+ batteries a day.
Might add I received my phone as a hand me down from someone at work. He only used it for a few weeks but kept it stock.

On any rooted ROM, i usually use tibu and delete buddy now, facebook, att, tether manager, devive update manager, etc..every possible background crap.
Every user is different, but with just calls and text, is not unusual for me to have 2-3 days before a charge.
Data sync and wifi off when not using data

Rxnelson the about phone says display. But that is the case on almost all phones. I have my auto off set to 1min

You can also try following basic methods:-
1. Turn Off: GPS, WiFi, Screen Rotation, Bluetooth, APN, Vibration, Animation etc.
2. Minimum Screen Brightness Settings
3. Minimum Screen Timeout setting.
4. Dont install Widgets based apps on home-screen
5. Kill the un-necessary background apps from Task Manager.
6. Use black theme in apps.
Thanks

Something I've found helps a lot is rebooting every morning. I'm running Zeus and noticed that the first day after a reboot I get great battery life (light- to medium-use would leave the battery at 50% after 12 hours). By the second or third day, I'd barely make it through the day. Since I've started rebooting every morning my battery life has been great. I also used BetterBatteryStats to help figure out which apps were keeping my phone awake. I learned that the Stocks app runs in the background waking the phone regardless of settings. Juice Defender is really a waste of time - you'll get better battery life by figuring out what's killing your battery and getting rid of it than having Juice Defender disable all of your phone's features when the screen is off(while using battery itself).

Man your battery life shouldn't be that bad. If it isn't a bad ROM flash then you could have a bad battery. Sometimes batteries die after a few months.
I did a lot of testing for apps and whatnot to try and see if I could maximize battery life. I tried all the juice defender and similar apps and didn't really like how they were killing off my services when the screen was off.
I found out that the main killers of my battery life were specific apps. When I used email apps with IMAP push services I noticed that they would kill my battery because they kept preventing my device from sleeping. I sometimes need about 18 hours in a day before I can charge so I really wanted to maxmize the battery as much as I could. I monitor new apps when I install them. Some seem sneaky so the battery stats might say that the app is only using something like 4% but it is also making the Android OS keep alive and use a higher percentage. I have about 70 apps installed but deleted most of the apps that seemed to kill my battery. In an 18 hour day now it is common for me to have at least 50% or more battery left over. It did take me a while to get this kind of battery life though. I was getting pretty frustrated for a while.
I'm running stock GB 2.3.3 (Rogers) and I am on the Bell network in the Great White North.
