    Default 4.0.4. update killed my battery life!!

    Has anyone else been experiencing problems with their battery life since this update? I went from charging my phone once a day to now 3 or 4 times a day! I called sprint and the guy said there is no way to switch back. Any solutions?

    Many are. Possible solutions are...

    1) Perform a factory reset
    2) Set wifi to sleep when your screen off, or even turn off wifi entirely when you're not using it.
    3) If you have an sd card installed, remove it, and see if your battery life improves.

    If these things fail, you can always manually rollback to Gingerbread for now. I have a guide in this forum on how to do it.

    Most of the people that got the ICS update took some kind of negative hit. Mine was battery life and 4G stopped working. I called Sprint a bunch of times, and even went into Sprint stores and they told me I was pretty much SOL. Or they played stupid like you're the 1st person who has reported this issue.

    Anyway, after some serious complaining to Sprint I was able to get a brand new replacement phone from the them. Back on GB, battery is good and 4G works like a champ!

    Keep in mind, this took many, many, many, many, many calls and store visits to Sprint. But now I have a phone that works 100% the way it's supposed to work.

    I know that there are people here trying to help each other out by trying several things. But in reality you shouldn't have to take the SD card out to improve your battery life or try all these crazy things. When things were clearly working before the upgrade.

    This was a big FAIL on Sprint and Samsung.

    Good Luck! I feel your pain. I was there for a whole week. Back on a brand new GS2 with GB. :-)

    @CRS you couldnt have said ot ANY better my friend.. Just got off the phone with them and they are reccomending a factory reset. The reason they cant send me a new phone is because any new phones they send out will have the current version of software so i wouldnt get GB i would have ICS again. .. I thought that was bull. If the factory reset doesnt work im callin my provider attorneys at legal shield and having them write a nice letter to sprint for me

    That's bull!!!

    None of the new GS2's have ICS in them. Seriously...they must think we are morons.

    They all come with GB. When I was getting the paperwork done for my replacement phone, the Sprint Rep told me all the new GS2s come with GB.

    Have your friend write a good letter to Sprint. This all was a cluster and we, the paying customers are getting screwed! Raise hell and someone will eventually listen.

    Huh...my husband just talked to a csr this morning who offered us a deal on two E4GTs (which we are getting Friday) , and she said they would come with ICS on them. I know better than to believe everything customer service says, but I'm interested to see which csr us right...

    LmaO! I see they must be wanting to get rid of SGII to make room for their new flagship phone the SG3.

    Try downloading better battery stats and see if you have the AudioOut_1 bug under partial wakelocks. If you do, turn off all system sounds like touch sounds, lockscreen sounds, dial sounds, etc. I had the bug and after turning those off my idle battery drain dropped to 1-2% an hour.

    I am so frustrated with this right now. I spoke to Sprint on the phone and they said that I would have to come back into the store and they can push the original OS back onto the phone, but they also told me that this was 100 percent Samsung's fault -- that they pushed the upgrade and Sprint had nothing to do with it. I went to the and emailed the support staff as well as the CEO, because why not?
    I've added the Advanced Task Killer, but it just seems like its not going to get any better. I don't want to carry my charger with me everywhere -- is going back to Sprint the only option?
    I am not as tech-savvy as you guys seem to be, so can you tell me if there are any other options?
    Thanks!

    I wonder if there's a chance of getting an SGIII replacement rather than an SGII?

    Sprint stores are saying to bring it in or do a hard reset and the problem is supposed to go away.. very nice of them to know this problem exists and not reach out to their customers and help them... Thank you Samsung... and thank you Sprint!

    If you clear the cach partition, it fixes the battery issue. At least, it did for me. You have to go to the Systems Recovery Page. To do this, its preferable that you have full battery). Then turn your phone off. Then you have to hold the Power Button and the Increase Volume button at the same time. Let go off ONLY THE POWER BUTTON right when you see the Samsung Galaxy S II logo. This will get you to the systems recovery page. Then, using the volume buttons scroll down to where it says clear cach partition. Select it using the power button. After it clears it, click Reboot Now. It will take a little longer to reboot but just let it do its thing. Then when the lock screen comes up, unlock it then wait. There should be a window that pops up saying "Finalizing Update." Wait until it finishes and you're good to go.

    What do you loose when you clear the Cache?? Passwords? Cookies? stuff like that...
    your data and apps are still there right?

    Yes, this isnt the same as a Factory Reset. You will not lose anything.

    I cleared the cache, and it brought up the Finalizing firmware box. That has been "running" for about an hour and a half. how long should that run. And if I restart or pull battery to stop it will that cause big damage? what is my proper action at this point?

    take it to Sprint if you can...you might be able to get a brand new phone if they see it continously updating like that...

    @rdrean if that box stays there just click cancel. If the battery issues persist then clear the cache partition again.

    If you have an Exchange mail account setup you should remove it and re-add it. As absurd as that sounds it fixed my battery issues on both 4.0.3 and 4.0.4.
    As I type this i'm 93% battery after 2h 55m.

    No need for factory reset. Totally unnecessary to do that.

    I had the same problem. After the most recent update my phone was practically unusable due to horrific battery life. I performed a factory reset and was rewarded with 17+ hours on the first day thereafter. I am not exaggerating. It is a minor pain in the *** with a huge upside. It worked great for me.

    Ditto on the FR. Phone goes to Deep Sleep. And other apps seem to perform better. 22 hours on battery with 20+% charge remaining this morning.

    I've done most of the suggestions recommended except a factory reset and have gone from 6hrs to 15hrs with light to moderate use. Cleared the cache but am thinking about a FR seeing these crazy hours you guys are getting.

    I did this anyway, was not having battery problems, but probably makes sense every once in a while. I did get a popup that said it was finishing update, wonder if the FH13 update hung and I didn't know it. I wonder if this same thing happened to those that the FH13 didn't fix their battery issues? Maybe this helps someone else.

    What exactly does clearing the cach partition do? What am I losing by doing this?
