ICS 4.0.3 Battery Life

Last night I did what lunatic59 suggested. You HAVE TO DO A FULL FACTORY RESET. Meaning you have to reformat the device memory, usb storage, and your SD card if you have one installed. Just make sure you backup your important files. I was having horrible battery life as well until I did a full factory reset. Now I'm having amazing battery life and I'm using stock ICS.
Are you running stock? Or are you rooted?
What about any battery apps like juice defender?
Thanks!

Are you using stock or a 3rd party launcher like Nova or Apex?

Calibrating the battery did not help. what did help was to do a factory reset. It's a pain, but it works. My battery life has improved exponentially.

Mines worse. I'm having to charge it in the middle of the day and I'm using it just as much as before.
Troubleshooting this is likely going to be a one-thing-at-a-time, process of elimination, er, process. 
Start by shutting off your wireless and network functions for at least an hour, two would be better. Then check the battery graph. If it levels off, your problem likely has something to do with communications. If so, then you may want to go into each app that uses the communications and set the update frequencies to longer times. Check the settings in e-mail, FaceBook, Google+, etc. etc. Then see how it goes from there after you turn the comms back on.
If turning off the comms doesn't work, try turning off things like active wallpapers and other background processes. You may find it moderately useful to go to the task manager and Clear Memory. Only do this one time. It serves no purpose to bang away at this repeatedly.
One of the things I had to do with GB was to just delete all downloaded apps and then reinstall them one at a time and wait an hour or so to see if any of them were trashing my batteries. Found a couple of culprits and perma-deleted them.
The above is no solution by any means, but it may help to get you started. Frustrating, I know.

I know that doing this will basically reset my phone and make it seem like Its brand new.
Just to make sure though, diong this required you to redownload all your apps, correct?
What else did you need to do to get it back to normal?
thanks

Make sure you have latest version of kies. Back up your music, pics, email, SMS you want to keep, and browser bookmarks. kies can be frustrating so be patient.
Your apps will download automatically. Once that's done, restore your stuff.
The most time consuming thing for me was to organize all my home pages, widgets and my docked apps.
I use google for calendar and contacts, so that wasn't an issue for me. If you use outlook you may have to make a sure you're all synched up before you do the reset.
It takes a while, but the difference on phone performance is amazing.
Good luck.

I did a hard reset of the OS as recommended (turn off phone, hold up and down volume buttons and power buttons together until menu appears, follow menu to do a reset). When the phone restarts, you can login into your google account and it will immediately download ALL the apps that were in your phone before, effectively installing them from scratch (automated = awesome).
The battery lasts much more just by doing that, yet there is one app that keeps consuming the battery a tad faster. I found it to be google play
. If you hold the "home button", it will show you the tasks in memory. Swipe google play left/right to remove it from memory after using it and that's it! Battery now is LEVELS of magnitude more lasting than GB or ICS-upgraded.stock ICS is good... Have fun!!!

FYI, after a factory reset, the Play store will show a lot of power usage because it's syncing and restoring your apps. It should settle down on it's own.
After I upgraded to ICS my battery usage stunk bad. Could not get through day without having to throw back on charge. I was very unhappy. THen I saw the above, either this one specifically or one similar and I tried it. I am happy to say that my battery drain is to back to what it was before (I could at least make it to bedtime before needing charge) if not maybe a little better. I really cannot say if it is better yet. Anyway, thanks for the forums.
Now I wonder if I should try that resetting and reloading thing that people are talking about......?

A factory reset made all the difference for me. It's been a few days since I did the reset. Today I'm still at 82% at 11 AM after unplugging it around 3 AM (don't ask, the dogs knocked loose a pool hose and water leaked everywhere).

My battery life is horrible now. But I think it may be because my OS is sucking down a GB of data a DAY. I can't get it to stop. I've posted a thread and would be grateful for any help whatsoever. I turned off my backup, background stuff, etc.

I did a reset of the OS and Google Play re-installed all my apps automatically (huge battery drain). As I was told by lunatic59 (see above), Google Play would stabilize after all install and updates and battery would be better. I also did the drain battery and recharge fully (under USB - slower charging is better). Battery Life is PERFECT!!! Only 1 of my apps seems to be using the battery like crazy when loaded in the memory - Facebook. If I open Facebook, everything is ok, but when I press home or back, Facebook for some reason keeps updating (battery drain and data usage hog). I remove Facebook from active memory (hold home and swipe Facebook app left/right). Battery is perfect again. I have gone over 24 hours with going online sporadically, watching youtube videos and talking on the phone.
I noticed this by using CPUspy. When Facebook is under memory, it seems the CPU runs at 200 MHz, and doesn't go into deep sleep... I ran this test with several of my apps for about 3 weeks until I found the source.
