    I think I found the answer. The optimizer that determines the best setting...3g, 4g or wifi is constantly searching for another wifi connection even though one is already connected. I checked it myself and sure enough, searching continues. I can't find the method to turn the optimizer off though. At least we have a lead.

    I really think that the scanning is the issue. Since I turned off wifi, my android process has dropped dramatically. The only problem is that I can't find out how to turn off the optimizer. There are old directions, but not updated for ICS. Settings, wireless and network...I only have 3g as a choice.

    yea you're probably right. I just wish i could find the source of the major os usage....

    Its the constant scanning. If we could find the way to turn that off I think we'd be good.

    Exactly. With the OG Epic, the GB update broke the GPS for most users. That was back in Nov 2011 (I think). As far as I know the problem still exists.

    The person who found that could post it on the Sprint Community forums and maybe a Sprint employee will see it, but again, I don't think we should expect a speedy fix from Sprint / Samsung.

    Yeah, I wouldn't expect too much with the first line support you reach. I have no idea how (or if it is possible) to get someone on the phone who is deep in their tech department.

    Talked to tech support. They recorded the problem and will send it up the line. It is definitely the wifi issue searching after connecting. Samsung's number was given to me to call as well in order to report it to them. If you want to call the line, it is 800-726-7864

    I spoke with Sprint. The first person I talked to sent me to "tech support". I explained the issue and was asked if this video would help:

    Android Ice Cream Sandwich - Galaxy S II - Wifi Working ! - Update #5 - YouTube

    First, there is no fix listed in the video. Second, that is the international version. Third, that video is from last year.....

    Then I was asked if I have the Skyrocket (ATT's version of the Galaxy S2) :mad: :mad: :mad: :mad:


    Anyway, the guy said no one had reported this issue and he will call me back tomorrow and let me know if this has been "entered into the system".

    After my experience with the OG Epic, I don't have much faith this will get resolved by Sprint any time soon. I guess I will have to be on the look out for a fix from the dev community.

    Here's how I fixed my battery life issues.

    1) Completed the ICS update and noticed power was dropping quickly.
    2) Shut down my phone.
    3) Removed my battery, and waited 5-10 seconds.
    4) Replaced battery, and started up phone.

    That's it. Once I did that, my ridiculous battery usage completely went away. My guess is that there was some kind of battery power history behind the scenes that wasn't configured correctly on ICS. That got reset when it noticed the battery was replaced and is probably why folks have had success doing a factory data reset as well. But I'm not an Android expert so who knows. I just know it worked and I didn't have to reload all my stuff.

    FYI, my estimated power percentage when from 19% all the way down to just 5% after I removed/rebooted, so something was definitely off.

    G'luck!

    With the issues that I seeing on here, would you recommend updating? I just received the OTA update, but I chose to do it later.

    Toddville is listed as the location for my weather info on the Lockscreen and I can't figure out how to change it. When I go into display and choose I want the weather on the lockscreen there isn't an option for location. Thanks :)

    My phone just updated about an hour ago and so far the swipe function on my keyboard fails and I can't set the ip address under the advanced settings on my wifi. My work has wifi but you have to have an ip address. Our i.t. guy set it up for me but in order to connect anywhere else outside work, I would have to go into the advanced settings and turn it off. Thanks in advance.

    Does anyone know how to get to the "face unlock" feature. I looked under security and couldn't find it.

    it is under security.... you have to go into it a little further though. it should say something about choosing your lock screen feature its in there.

    just an fyi to you a lot of us have been experiencing a rapid battery drain with the wifi on. We think it has something to do with ICS....

    OK, it's been 3 days, 18 hours and change, or 90 continuous hours. 90 hours! That's outstanding! Even more so because it's on my slightly less capacious Sprint battery, not the Japan-made (high quality) Samsung brand battery that came with the phone. My backup battery that I use for the frequent battery-killing charge/discharge cycles and keep my Samsung battery at full force for times when I need every last minute. I'm not going to discharge even that one past 20%, although I have no doubt that it could get into its fifth day if I pushed it. (Lithium secondary chemistry doesn't do well with deep discharge, so draining it to zero as a quick way to turn a 90 hour+ battery into a 9 hour battery.)

    Here are some things to ponder:

    1. The phone and battery are only a couple months old.

    2. I've kept the phone dead stock, installing only applications (not utilities or replacement OS components other than a user mode antivirus program).

    3. I used the stock Samsung-made ICS zip file to do the upgrade.

    4. After the upgrade, I found a lot of settings that affect battery life altered, and some new features like "Power saving mode". I reset all of them to more or less the way I had it set up before. I set the new Power saving mode to kick in at the most aggressive 50%, assuming that the last 50% would be a lot shorter than the first. (Turns out it wasn't.)

    5. I installed the test battery after a full charge, using the included Sprint charger.

    6. Swapping batteries caused a temporary power outage in the phone, causing it to reboot. I'm told this is called a hard reset. Although I gave ICS 12+ hours to finish any background processes before the reboot, I did notice a lot fewer system processes after the hard reset. I didn't kill any of them so as not to bias the test.

    7. I spent an hour or two going through the phone and verifying that it was still set up the same as it was before the reboot, and took one unexpected phone call, but didn't make any calls or use the phone to do more than check the battery state, so as not to bias the test results. No software updates were done during that time. I did clear messages, not knowing whether it cost more power to keep the reminder active. I did keep the Wi-Fi radio on during the test. The 4G (WiMAX), Bluetooth and GPS radios were kept off.

    Why did I not use the phone? Isn't that abnormal? The obvious answer in this case is that the problems being reported from those fresh off their ICE upgrades was that ICS (and only ICS) was sucking up battery power at an unacceptable rate. Since PCS phones vary their output power automatically, there's no simple way to calculate how much energy a call would consume. Likewise, since the display was set to auto mode, which varied the brightness in response to the ambient light levels, I kept it off most of the time so as not to bias test results. Using the phone has no bearing on whether or not ICS by itself was draining the battery.

    My conclusion is that those who experienced what they believed to be a battery-hungry ICS distro is more likely to be a battery-hungry ICS new user. Other possible factors include:

    1.) Failure to reset the user settings. I noticed from the comments than many users assumed that ICS was the problem, and tried rash remedies like clearing all personal information off the phone. But I didn't read a thing (that I didn't write myself) about the easy to access (and I thought obvious) "Settings" menu. This may be a case of "new toy syndrome" and a rush to judgment by users who hadn't considered every possibility.

    2.) New User Syndrome. We all want to check out the new install, so it only follows that we'd be using prodigious amounts of power in doing so. And those who are immersed in discovering all they can about the new attraction are less likely to pay attention to the difference between the way they're using the phone at the time and how they normally use it. It could be that simple.

    3.) Background install processes. IME with embedded operating systems, it's not uncommon for the embedded hardware to be "just enough" to do its designed task, with little headroom. That makes it necessary for the OS to cope with CPU and RAM-intensive tasks like decompressing, organizing, configuring and installing new files by using every available shred of system resources that aren't needed for normal operation to perform these tasks in the background.

    For example, the TiVo daily Program guide update takes anywhere from a few minutes to an hour to finish as seen through the graphical user interface (GUI) on the TV screen. However because the TiVo runs the Linux kernel and filesystem for the system, it's possible to use another user interface that's created by a well-known TiVo hack: the BASH shell and the GNU utilities. I've used these tools to monitor the runnung processes and CPU / RAM usage and can say with certainty that the daily update doesn't end when the GUI update display ends. It can take hours for the rest of the process to complete. GUI-only users can see this too if they watch the To Do List. They'll see new scheduled programs appear from time to time as they're added to the database. Other DVRs act this way too.

    Another thing that could be happening is an exhaustive recalibration of the hardware by the new OS software. There have been quite a few reports of poor radio performance right after the ICS upgrade. For me these have settled down in a reasonable amount of time. If anyone is still having radio problems, please speak up.

    4.) Unfamiliarity with the new user interface. Those who are experienced with the old version of Android might be misinterpreting what the new version is telling them. For example, the "(time) on battery" counter might be seen as a "battery time remaining" display. That's what I thought at first!

    5.) The hardware. The new install and the reduced battery life could be a coincidence. Rechargeable batteries don't last forever, and it's possible that the big install was the last straw for an already exhausted battery.

    DISCLAMER: This is only my best guess, and should be considered an opinion. The testing that I did wasn't rigorous or scientific, and all of the data at this time should be considered preliminary. Time will tell how things work out. If Samsung releases a new version of ICS, that would indicate that there are problems with this first release. Likewise, if the complaints stop coming, that will be telling too. My only interest is to figure this out, and have no intention to impugn the experiences of others, their good word or to insult anyone for any reason. Please accept this report for what it is and no more. Thanks!

    That 47% figure is a percentage of total CPU usage, not percentage of total CPU capability. It's different and confusing. It can say 47%, but that can be a 47% share of a total 1% actual CPU usage or 100%; you don't know from it as it is.

    To see actual CPU state, you'll need to install a 3rd party utility, near as I can tell. I have system tray utilities that monitor CPU and RAM usage on my Linux and Windows machines, and wish I had the same for Android's Mac-style top bar. I'd love to see an Android port of GKrellm.
