Battery life comparison between 1.0.2 and 1.1.1

I had to have Apple Care send me a replacement phone because of battery issues.
I received the replacement phone, and interestingly, it still had the 1.0.2 firmware on it.
If enough people are interested here, I can run a fairly scientific test to see if there's any difference between 1.0.2 and 1.1.1 in regard to battery life.
I could leave the 1.0.2 software on it, charge it fully, then at 10 pm, put it in a specific place in my house, then see what the battery is at @ 7 am. Then, the next day, I can update to 1.1.1 and do exactly the same thing with the same settings.
But if the battery issue has been put to rest, or if people think this isn't a scientific test at all I don't want to waste my time.

Your post is helpful in that it points out that it'd be a very difficult thing to do a scientific test that proves anything.
In your usage, you left out surfing the web, which I do quite avidly. I also check my email much more frequently (every 30 minutes, as I've said). I can't test for surfing the web while I'm sleeping.
Your saying that updates have nothing to do with the battery is not at all a scientific case study and has very little resonance, but it's great that in your personal experience you haven't seen a degradation in battery life. A bug can rear it's ugly head in many different places, and your usage of the phone may not hit it if in fact there is one.
Just as an endless loop in a program can cause a computer's CPU to spike if an uncommon set of events leads to it, something could be happening with the phone for some users who are using their phone in a specific way.
So, having said that, I think I might've answered my own question in that there might not be any scientific way to do a test.

    Hi i received the nano 7th gen for Christmas and I only seem to get 5 hours of battery life. I use the Bluetooth and Nike app so I expect more drain on the battery.  But I got more time out of running with my iPhone. Does this sound normal? I thought I should get close to 30 hrs of just play time alone.
    ALso, my wife got me the Belkin armband to run with the nano but I sweat through the band resulting in the back of the iPod to get wet. Surely this is not good. Anyone have a recommendation for an armband that keeps moisture away from the pod?

    iPod Nano are small and they don't use Wi-Fi access so you get less power time on a Nano. As for iPhone, since you got apps, Wi-Fi + 3G access, and everything else, they give you more time so you can keep using. Nanos are ment to listen to music, listen to radio, view your photos, watch videos (without Wi-Fi) and since you got BlueTooth on the nano, it counts as wireless access so it drains your battery faster.

  • I am getting a flashing ad to upgrade to increase battery life.  Is that from Apple and is it safe?

    i am getting a flashing ad on my scrabble app offering an upgrade to increase battery life.  Is that from Apple and is it safe to download and will it truly increase the battery life.   I play scrabble and words with friends, i do not watch videos or anything and the battery life *****

    The iPhone 3G can not be updated anymore so don't click ads like the they don't work. Also the iPhone 3G is old enough that it needs a battery change. You can go to apple or an authorized service provider.

  • E6 battery life: difference between Anna and Belle

    Overall, I like the user experience of Belle. What really sucks is the battery life: one day or less. Now I've found a "guide" to flash back Anna and am considering this step because I've read more than once that Anna is better on this side.
    Sincerely, when I had Anna I didn't notice these great performances, but maybe it depended on a young battery. So now I'd like to know if anyone can support the choice of Anna for increasing the battery life.
    Thanks

    Hi Pepelemoco,
    Discussion of the non-official methods you are alluding to are not permitted on these discussion boards. Not to mention it will void your warranty, and may cause your phone damage. A general rule of thumb is that no firmware is able to be downgraded. If you are having issues with your battery life, have you checked that you have not recently installed an application that may be causing this? If you believe you haven't, then try re-installing your current firmware via Nokia Suite. Yet if this doesn't work, then a three-finger hard reset may be in order, and if this doesn't work either, then finally a trip to your local Nokia Care point for them to take a look at.

  • T410 vs T410s [battery life comparison] ?

    I'm currently thinking about buying either T410 or T410s laptops. T410s is tempting for its size and nice form factor, but I've read that there are some notable differences in construction between it and the t410, and one of them is quite different battery construction, which may result in lower battery life in t410s compared to t410.
    As both mobility and battery life are important to me, I need to decide which one is more important - T410 is a little bulkier and heavier than T410s, but may work longer. That's where I need Your help - what are the differences?
    I'd like to be able to get about 4 hours or more of DVD playback, with all desktop effects turned off, wireless off, about half of monitor brightness. Is this possible?
    And what about battery life while browsing the internet wirelessly? Can You give any examples of usage and estimates of battery life for both T410 and T410s?
    PS.: As I value mobility (as previously said) I think I'd choose the 6-cell battery and Ultrabay battery. (I know it's important)

    hey ssbc,
    i recommend using this psref : http://www.lenovo.com/psref/pdf/index.pdf
    to compare the difference in specs.
    for the battery consumption, do note that the consumption is based on usage, brightness of screens and other factors.
    thus if you would like to do a comparison, both units should be using the same power manager versions and both be at the same settings

  • [AS-CS5] Comparison between text style range and character style

    Hi,
    It's been a while since I'm not coming on this forum ...
    I'm looking to make a comparison between a "text style range" and a character style.
    I have no problems, except for the comparison of "fonts".
    myCurrentText = text for char…
    theStyle = character style id…
    I try:
           if (applied font of myCurrentText ≠ applied font of theStyle) then set theCharDifference to 1 
    The selected text give me:
           font "Minion Pro        Italic" of application "Adobe InDesign CS5.5"
    and the character style:
           "Minion Pro"
    I try "set theTextFont to font of applied font of myCurrentText" -> Error
    This is my script (it's too long to post here) <http://db.tt/BLoGPiN>.
    Loot at the "on CheckCharacterDifference(myCurrentText, theStyle)"
    TIA.
    Oli.

    I've written this, but I do not know if it covers all cases ...
    Someone?
    Thanks.
    Oli.
    set theText to item 1 of selection
    set theStyleChar to properties of character style 2
    -- analysis of the properties of the text

  • Can't get a comparison between a folder name and a string to work

    Dear community,
    I have a really simple ExtendScript-example that I just can't get to work and I have no idea what could be wrong. I'm trying to write a script that goes through all the items in the project panel and stores references to all the folders which names are like "layer1", "layer2", and so on, in an array. This is the code that should alert 3 times in my case, but it doesn't alert once..
    for (var i=1; i<=app.project.numItems; i++)
        if ((app.project.item(i) instanceof FolderItem) && (app.project.item(i).name == "layer"+i))
            alert("found folder = " + app.project.item(i).name);
    Inside the project in the root-directory there are 2 comps and 3 folders named 'layer1', 'layer2' and 'layer3' - so I should see 3 alerts when executing the above script. For testing-purposes I changed the second part of the if-statement to a 'static' value like so:
    .. && (app.project.item(i).name == "layer1"))  --> then it works! But I need a dynamic solution..
    Thanks very much for ANY help in advance!
    Greetings,
    Gilbert

    I just tried the code and it only alerted once for me. The issue with your code is that it requires the "Layer" named folders to always be the first x items in the project file. So what is happening for you is that...
    If any item appears before the first "Layer" folder then you are effectively comparing random names to each other that will never match.
    ItemSomethingElse
    RandomFolder                 == Layer1     (false)
    Layer1                              == Layer2     (false)
    Layer2                              == Layer3     (false)
    Layer3                              == Layer4     (false)
    Layer4                              == Layer5     (false)
    ItemSomethingElse
    What you need to do to keep it dynamic:
    1) Gather instances of all the folders in your project into an array.
    2) Loop through that array checking for indexOf "Layer".
    3) If there is a match...
    4) Compare that name in another loop. You'll have to determine the max number to loop through for your search, like 25 or 50 or something that won't loop forever.
    5) If a Layer# match is found then run your alert.
    ItemSomethingElse
    RandomFolder                 indexOf("Layer")     (false, do not add)
    Layer1                              indexOf("Layer")     (true, add instance to folderArray)
    Layer2                              indexOf("Layer")     (true, add instance to folderArray)
    Layer3                              indexOf("Layer")     (true, add instance to folderArray)
    Layer4                              indexOf("Layer")     (true, add instance to folderArray)
    ItemSomethingElse
    So something like this should work:
    var folderArray = new Array();
    //Loop through project grabbing folders with layer in the name
    for (var i=1; i<=app.project.numItems; i++){
         var curItem = app.project.item(i);
         if(curItem instanceof FolderItem && curItem.name.indexOf("layer") != (-1)){
              folderArray[folderArray.length] = curItem;
    //Set cap for number appended to "layer"
    var cap = 25;
    var curName;
    var folderArrayLength = folderArray.length;
    //Loop through new "layer" array
    for(var l=0; l<folderArrayLength; l++){
         for(var c=1; c<cap; c++){
              //Dynamic name
              curName = "layer"+c.toString();
              //Current folder name
              folderName = folderArray[l].name;
              //Compare them, alert if the match
              if(folderName == curName){
                   alert("found folder = " + folderArray[l].name);
                   break;//End comparison once found

  • 3G battery drain comparison between pandora an other streaming apps

    Has anyone noticed if Pandora seems to be more battery efficient in streaming over 3G than other streaming apps like last.fm or iheartradio? Ive got last.fm and pandora both set to higher quality audio over cellular.

    Just in case anyone else is experiencing the same or similar scenario that I was (see first post), turns out that the Apple Care Geniuses determined that the PMU (Power Management Unit - I think the "U" is for "unit" anyway), was corrupted or not working properly, so too much power was being used for tasks that shouldn't have used up so much power.
    They replaced my unit, it may or or may not be a refurbished unit, although it looks new and was manufactured on a later date than the one I brought in.
    The Geniuses were very helpful and didn't just turn me away saying to "turn down the brightness or turn off WiFi when not in use" which I do anyway.

  • Comparison between standard MPB 15" and Retina MBP 15"

    Hi to everyone!
    I'm about to replace my 2007 MBP with a new one! I want an advice about which one to choose between the standard MBP 15" with some optional or the stock MPB Retina 15". I've a budget of 2000 US$ that is enough to purchase both with the educational discount that I can ask because I'm a student.
    In the table I've written all the specs of both the MPBs.

    price: 1999 US$ (with edu discount)
    price: 1999 US$ (with edu discount)
    by the fact both cost me the same, I'm a bit unsure on which one to buy!
    which one has the best performances? which one has the best value for money? for what regards working with windows on bootcamp, is the retina display suited for the job? what I mean is if windows apps do properly support a so high resolution (I work a lot with computer graphics).  
    thanks to everyone in advance
    (I apologize for any grammar error but I speak english as a second language)

    Welcome to the Apple Support Communities
    I recommend the 15-inch MacBook Pro without a Retina display. In a MacBook Pro, you can upgrade the memory and hard drive without voiding the warranty, and the MacBook Pro with Retina display has got everything soldered into the logic board, so repairs are much expensive with the MacBook Pro with Retina display. Also, the Retina display is only needed for some specific jobs, so if you are going to use the computer for basic tasks, the 15-inch MacBook Pro is perfect.
    Note that Windows has got a resolution limitation, and you may have problems with some applications because of the high resolution of a MacBook Pro with Retina display, so you may have to reduce the resolution.
    Also, if you buy the 15-inch MacBook Pro, buy it with 4 GB of memory. After buying it, buy more memory from OWC or Crucial and install it in your computer. You will save a lot of money

  • Comparison between constants in class and interface

    Hi,
    I have recently read an article which says it is a better use of your memory if you declare constants in an Interface rather than in a Class. Can any one explain this is more detail? Have a great day.
    Thank you,
    npaila

    @ricardo_moral
    Hm ...
    we are talking of constants in this topic - constants are always final, otherwise it would not be garanteed, that they cannot change. Also we are not talking of holding a copy of this constant field in a class, we are talking of directly referring to this static final field, regardless if it is declared in an interface or in a class.
    I prefer using an interface - my reason is that I can use it the same way, I can use a class, which declares this constant - via qualifier - AND I can implement it, if I want to - so, I follow the swing route and declare constants, which are shared by many classes, in an interface - but I implement it only there, where these constants are heavily used.

  • I've had my iPhone for just about 1 month and within the last two days the battery life seems to deplete in minutes and the phone gets warm to hot within 5 minutes of use. Does anyone having this issue?

    This is very upsetting .  This product seems to be very poorly made for the big bucks they are getting for these phones.

    Literal minutes? Or is that an over exaggeration? If you do mean minutes, and the device is getting hot, it would be an obvious hardware issue. Take it to an Apple Retail Store or call AppleCare. If you want to try to troubleshoot the issue, refer to http://www.apple.com/au/batteries/iphone.html to turn off some of the irrelevant settings. This is obviously not an issue with every iPhone and it appears you've just had some bad luck.

  • IPhone 4S Battery Life: Best solutions and procedures for 1st time user: 1-Do you have a battery life issue (learn first what the usage time spec is about) 2-What can you try to remedy the situation without reading 500 pages of posts

    What follows is a grouping of some of the most fruitful procedures - from what I've seen in the biggest battery life issue thread - and some background information and discussion for solving or improving the battery life with the iPhone 4S and may be applicable also to devices on which iOS 5.0/5.0.1 has been applied. Credit goes to the respective users who contributed this information to the forum and they should be commended for doing so. This is not a final listing. The goal here is to provide a first stop sort of knowledge base document for newcomers instead of having them perusing the never ending threads where the wheel is reinvented on every page...
    Please don't post your questions, usage screenshots, or claims that it worked or not for you or anything here except PROCEDURES/DEBUG STEPS/SOLUTIONS or improvements to the procedures already listed here. Try to use point form and to be as concise and clear as possible. Hope all this helps.
    Thank you and good luck!
    General info and specs
    First, take a look Apple's battery tips, info and specs(obligatory reading for all Iphone 4S users - read it once and for all):
    http://www.apple.com/batteries/iphone.html
    http://www.apple.com/batteries/
    ... you didn't read it? loll Always remember this i.e. the definition of "usage":
    Usage: Amount of time iPhone has been awake and in use since the last full charge.  The phone is awake when you’re on a call, using email, listening to music, browsing the web, or sending and receiving text messages, or during certain background tasks such as auto-checking email.
    I'm still not convinced you read the links so here's what Apple has to say in terms of fine tuning your battery life:
    Optimize your settings
    Depending on how they are configured, a few features may decrease your iPhone battery life.  For example, the frequency with which you retrieve email and the number of email accounts you auto-check can both affect battery life. The tips below apply to an iPhone running iOS 5.0 or later and may help extend your battery life.
    Minimize use of location services: Applications that actively use location services such as Maps may reduce battery life. To disable location services, go to Settings > General > Location Services or use location services only when needed.
    Turn off push notifications: Some applications from the App Store use the Apple Push Notification service to alert you of new data. Applications that extensively rely on push notifications (such as instant messaging applications) may impact battery life. To disable push notifications, go to Settings > Notifications and set Notifications to Off. Note that this does not prevent new data from being received when the application is opened. Also, the Notifications setting will not be visible if you do not have any applications installed that support push notifications.
    Fetch new data less frequently: Applications such as Mail can be set to fetch data wirelessly at specific intervals.  The more frequently email or other data is fetched, the quicker your battery may drain. To fetch new data manually, from the Home screen choose Settings > Mail, Contacts, Calendars > Fetch New Data and tap Manually. To increase the fetch interval, go to Settings > Mail, Contacts, Calendars > Fetch New Data and tap Hourly. Note that this is a global setting and applies to all applications that do not support push services.
    Turn off push mail: If you have a push mail account such as Yahoo! or Microsoft Exchange, turn off push when you don’t need it. Go to Settings > Mail, Contacts, Calendars > Fetch New Data and set Push to Off. Messages sent to your push email accounts will now be received on your phone based on the global Fetch setting rather than as they arrive.
    Auto-check fewer email accounts: You can save power by checking fewer email accounts. This can be accomplished by turning off an email account or by deleting it. To turn off an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and set Account to Off. To remove an account, go to Settings > Mail, Contacts, Calendars, choose an email account, and tap Delete Account.
    Turn off Wi-Fi: If you rarely use Wi-Fi, you can turn it off to save power. Go to Settings > Wi-Fi and set Wi-Fi to Off. Note that if you frequently use your iPhone to browse the web, battery life may be improved by using Wi-Fi instead of cellular data networks.
    Turn off Bluetooth: If you rarely use a Bluetooth headset or car kit, you can turn off Bluetooth to save power.  Go to Settings > General > Bluetooth and set Bluetooth to Off.
    Use Airplane Mode in low- or no-coverage areas: Because your iPhone always tries to maintain a connection with the cellular network, it may use more power in low- or no-coverage areas.  Turning on Airplane Mode can increase battery life in these situations; however, you will be unable to make or receive calls.  To turn on Airplane Mode, go to Settings and set Airplane Mode to On.
    Adjust brightness: Dimming the screen is another way to extend battery life.  Go to Settings > Brightness and drag the slider to the left to lower the default screen brightness. In addition, turning on Auto-Brightness allows the screen to adjust its brightness based on current lighting conditions.  Go to Settings > Brightness and set Auto-Brightness to On.
    Turn off EQ: Applying an equalizer setting to song playback on your iPhone can decrease battery life.  To turn EQ off, go to Settings > iPod > EQ and tap Off. Note that if you’ve added EQ to songs directly in iTunes, you’ll need to set EQ on iPhone to Flat in order to have the same effect as Off because iPhone keeps your iTunes settings intact.  Go to Settings > iPod > EQ and tap Flat.
    Usage specs for the 4S - http://www.apple.com/iphone/specs.html:
    Talk time: Up to 8 hours (12.5% per hour drain) on 3G, up to 14 hours (7.1% per hour drain) on 2G (GSM)
    Standby time: Up to 200 hours (0.5% per hour drain)
    Internet use: Up to 6 hours on 3G (16.6% per hour drain), up to 9 hours (11.1% per hour drain) on Wi-Fi
    Video playback: Up to 10 hours (10% per hour drain)
    Audio playback: Up to 40 hours (2.5% per hour drain)
    So a scenario of normal usage could be for example: 4 heavy hours of 3G internet browsing (66.4%), with one hour of call on 3G (12.5%) and 22 hours of standby (11%) = 100%
    A battery life issue is a problem where the drain is really out of spec either during usage or standby or both. For example, multi-% per minute drain during usage or a 10% drain per hour during standby is problematic. Browsing the internet on 3G during one hour and losing 16-17% is not.
    Apple's test methodology for claiming the specs:
    http://www.apple.com/iphone/battery.html
    Procedures
    davidch tips (reset+full discharge recharge):
    Go through these steps to address the battery after updating to iOS 5.0.1:
    1. Reset all settings (settings app-> general-> reset)
    2. Go through initial setup steps (lang, wifi, siri, enable location, etc) and choose setup as new phone (don't worry your apps, data, contacts, mail will still be there). Do NOT restore from iCloud or iTunes (It can copy back corrupt settings)
    3. Turn off system location services timezone and iAd
    4. Fully discharge battery  (tilll it shuts off with the spinning wheel)
    5. Fully recharge battery (overnight if possible)
    In my experience this improves the Standby battery drain issue significantly in most cases.  It reduces drain from 2-4% or more per hr to 0.5% or less. It has worked for many, many users now. If it does not work after a few try's you may have a real battery or hardware issue and should contact Apple.  Good Luck!

    Now using davidch original steps and attaching the tweaks I made to get me more usage. As shown on page 29.
    Go through these steps to address the battery after updating to iOS 5.0.1:
    1. Reset all settings (settings app-> general-> reset)
    2. Go through initial setup steps (lang, wifi, siri, enable location, etc) and choose setup as new phone (don't worry your apps, data, contacts, mail will still be there). Do NOT restore from iCloud or iTunes (It can copy back corrupt settings)
    3. Turn off system location services timezone and iAd
    4. Fully discharge battery  (till it shuts off with the spinning wheel)
    5. Fully recharge battery (overnight if possible)
    6. Disable Siri 'Raise To Speak' and REBOOT *( if possible use another camera to verify the                 infrared is off after the reboot).
    7. Set emails, icloud and calendars to fetch. ** test. Mines on hourly.
    8. If your in a no signal and your phone is saying "Searching..." even after 10mins, reboot while in that area and after 1-2min it should say "No Service". This mainly applies to Verizon customers and improve battery life in these areas.
    9. *optional* Goto Settings > General > Network and you will see "Hotspot.." loading something, wait a few seconds and it should say "setup personal hotspot" then exit out.
    * I notice a great improvement after disabling this and rebooting. This increased my "screen on" usage or at least helped it. Make the change.
    ** I have not tested push yet to narrow down the drain but I had this change on my phone. I believe exchange push is responsible for some stand by drain. As for icloud, haven't notice much of a difference. Just try it for a day. My email still came in fast most times. Again still testing, will report back on these..
    buxbuster tips(wifi sync, iCloud):
    These are my own tested workarounds that worked for my iPhone 4S and seemed to have worked for others as well :
    Workaround number 1. Deselect wifi-sync in iTunes and press sync.
    If that doesn't work try :
    Workaround number 2 : Remove iCloud, reset network settings. ( I guess this won't work for you since you don't have it enabled ).
    If both workarounds fail, you can always try to completely wipe your phone. That also solved some of the cases out there.
    rolandomerida tips - i.e. buxbuster and additional steps:
    Finally, I solved the syncing error loop. My contacts are syncing flawessly again between my devices and iCloud, and yes, the battery stopped draining, which is the main topic here.
    I followed instructions from buxbuster (check his workaround a few pages up!) and an additional BIG step to restore contacts and syncing, as seen in a MacRumors forum.
    This is what I did:
    1. Make a backup of your Address Book, using the vCard option (or both, it doesn't hurt). Save it for later.
    2. In your iPhone, delete iCloud account. When it asks, accept both: delete AND delete from my iPhone.
    3. Reset network settings. The iPhone will restart, then will ask you to unlock the SIM card.
    4.Turn Wi-Fi on.
    5. Add the iCloud account again.
    That's for Buxbuster's workaround. For some, it might work just like that. My iPhone repopulated from iCloud after step 5, but I still had that "server error" on iCloud. I had to do some extra steps, since my Mac was not syncing to iCloud and couldn't edit anything on my Mac or iCloud. Syncing back had to be fixed, too. If not, the syncing loop would continue from my iPhone, and the battery would drain awfully again.
    1. In System Preferences -> iCloud, I turned Contacts off. I chose "keep on My Mac" those contacts, but I got an empty Address Book after a while. And a few minutes later, iCloud contacts were empty and my iPhone also. It is scary at first! Now, before importing that vCard backup...
    2. Turn Wi-Fi off. This is important, since your contact-empty iCloud will attempt to wipe your Address Book from your Mac in seconds after importing.
    3. Import your vCard backup to Address Book. Just drag it to your blank Address Book window; it asks if you want to import "x" number of cards. Of course, say yes.
    4. Turn Wi-Fi on, and then iCloud contacts on again (System Preferences -> iCloud). It will offer to merge your newly populated Address Book with iCloud (which is empty at this point). It should upload every single contact to iCloud, and then to your iDevices. If not, a fifth step would be to import the vCard file to iCloud, but it shouldn't be necessary.
    So, with iCloud syncing working correctly, there is no battery draining! Again, that was my particular issue.
    I can't tell if this is the single answer to the widely spread battery draining problem, but it sure can be fixed with these workarounds, and yes, Apple should address the problem with a future update, for we affected customers don't need workarounds in the first place

    Miless tips (full 800mb release of 5.0.1 and sanitizing a restore):
    As for 4S battery life. Try doing this,
    1. Settings>Location Service ... disable all location services you do not need. In particularly Facebook because it drains the battery a lot.
    Scroll down to the bottom at Settings>Location services>System Services ... Disable Setting Time zone, location based iAds, Diagnostic & Usage.
    2. Settings>Notification>Calendar ... turn off the Notification Centre.
    3. Settings>General>Reset ... do Reset All Settings. Doing this will not wipe out your iPhone. It will just Reset the network settings, location warning, keyboard dictionary, etc... but it will clear up some corrupted data there. Generally this will help.
    Try these 3 steps first... if it still drains a lot, try the following,
    4. Drain your battery down to 1%. Then charge it up using USB from PC ... not the charger. The charger output 1.0 A ( x 5V from USB ... you get 5W power). From PC, output is only 0.5A x 5V = 2.5W power. Charging is slower but trickle charge 4S helps the battery retain its charge better. I think it takes about 3-3.5 hours to charge full from USB/PC compared to slightly below 2 hours using iPhone charger.
    If after doing the above still could not solve your battery issues (mine with iOS 5.0 was ok up to step 4, but not iOS 5.0.1).... plug you iPhone to a charger (any charger), from iPhone, access your iCloud ... set it up if you havent. Back up your iPhone data to iCloud. if you do not have enough storage (only 5GB is free), go to details and select the apps you need its data backup, choose only those you really need and leave those unnecessary ones out. Back up your camera roll to your PC/Mac manually as it could be too big to backup to iCloud.... once you have it setup, make sure you are on Wifi ...  tap backup to iCloud from your iPhone. It will take a while if the file is huge.
    Once backup to iCloud is completed, plug your iPhone to PC/Mac and launch iTunes 10.5.1 (make sure you have 10.5.1)
    Click Restore. It will automatically initiate a download of iOS 5.0.1 ipsw for iPhone 4S. Wait for the whole process to finish, ie. download, restore software/firmware.
    Once its done, do not set up your iPhone from iTunes. Set it up on your iPhone. Go through the selection. When prompted, select restore from iCloud (from your iphone backup earlier). Keep your iphone plugged into iTunes while restoring backup from iCloud. Because while restoring from iClouds, some data will be synced from iTunes if you plug in, e.g. music, video, etc... unless you bought these content from iTunes store. Apps will be downloaded from App Store from the cloud.
    Once it's all done restored. Turn off your iPhone,.. and turn it on again.
    Now, hopefully your battery wont be draining so fast anymore. Usually it wont after this. But you need to charge your battery at least 4-5 cycles to stabilize the charge on the battery. I dont know why... but battery life seems to get better and better for me after a few charge cycles after all the above work.
    Good luck. Let us know if it works for you.
    W. Raider tips (Sirii):
    Bottom line for me of things that helped battery life are:
    1. Turing off Siri and Rebooting the phone by holding the Home button and Top button down, ignoring the slider, until the phone shut down. (turn off Siri, reboot, and check top front of iPhone 4S against a lesser camera like the front-facing camera on an iPad2 - making sure the IR sensor is off)
    2. Fully draining the battery, meaning using the phone until it shuts itself off from a drained battery and then recharging it to 100% about 4, maybe 5 times. I charged it both with a Mac and a wall charger.
    Hope this is helpful!

    jmm514 remarks (Twitter):
    I may have found something. I had Twitter disabled in my notifications, but got a tweet today that popped up on my home screen. Didn't know I had this enabled. At the bottom of the Twitter notification settings is the home scrren toggle. Since disabling this, battery life seems better. Considering there is no setting for frequency of checking for tweets, it appears the phone is continually connecting to wifi to check for new tweets.
    tmksnyder comments (notifications, corrupt data in iCloud):
    For me, I found my iphone on wifi mysteriously connecting to my mac.  I eventually narrowed it down to the Apple Move Trailers app which keeps a file in iCloud.  The phone was trying to sync the file with the mac in the background even when the Movie Trailers app was closed (hitting the red x).  Based on my macosx logs the iCloud process that was trying to sync was working directly between the phone and the mac without using itunes by connecting to an https address hosted on the phone.  It was connecting every 3 minutes and failing (while phone was awake or awake during during a notification).  I also found that iCloud control panel on OSX would error if I tried to delete the file.  I fixed it by removing the App and doing a hard reset which stopped the sync.  I probably could have turned off iCloud document sync in the phone but didn't think of that.  My battery life has greatly improved while at home on wifi.    I am now at 28 hrs standby, 2 hrs 20 minutes of usage, and 68% battery.  It was ok before where I could get 20-30 hrs standby and 6 -8 hrs usage.  My usage today was phone calls, 3g surfing, and music via bluetooth in the car.
    I also found even with Itunes iMatch, if I mass updated tages, art work etc, it would hit the phone on wifi even in standby.  I was amazed.   Granted if I am not doing updates, Match won't hot the phone so this was a once in awhile event.  I could drop my percentage by 5-10% in a matter of minutes when doing updates.   I think a lot of our problems are background processes, associated with iCloud, notification, and apps.  More features means more battery.   I think the key thing is to keep track of what has recently been added or changed if battery life gets worse all of a sudden.   It may be an app that was recently installed and if possible you may want to completely remove it and not just quit it.
    With twitter, i think it uses push notifications so it doesn't need to be running and actively poll on the phone. For instance , if i quit the mail app, i still will get mail notifications and can swipe the message and load mail. Apple Push Notifications servics maintain the connection to the phone and there are likely pings or connection checks  that occur for the service on an os level not an app level.  This minimizes the load so there arent a bunch of apps all runing and constantly checking.  The notification service , if it is contacted from twitter or another service with data, will check the settings you have registered to the with the apple push service and send the notification to your phone.  No matter what, there is a drain with notifications. M hunch is once one application is configured to receive notifications, connection checking occurs betwen the push service and the phone so it knows where it is on the network. If it is implemented correctly, these checks arent frequent if you are still and more frequent as you move. The other drain is for when the noification hits and is processsed.  If i get 9 emails over night, my screen just popped up for 20 seconds or so to process each message using battery.  I would even think that just go from low power to turning n the screen uses more juice than if the device was already on and i get the message.  On nights I get no notifications, I see a 3  or 4 percent drop.  On nights with a number of notifications, i have seen up to a 10 percent drop.  Besides notifications, wifi sync and icloud will poll on the local network and use up battery if the host computer is on and running itunes or trying to sync a data file that is corrupt (which i had with the apple movie trailers app causing my phone to drain).  For me turning off wifi sync and remving a corrupt file in icloud solved my battery issues and I get over 24 hrs of standby with 6 to 9 hrs of use and this is with all the normal location services and push serivices turned on.
    See http://developer.apple.com/library/mac/ipad/#documentation/NetworkingInternet/Co nceptual/RemoteNotificationsPG/ApplePushService/ApplePushService.html for more info.  I think it has a good overview of how the notifications work.

    Well seems like that rumor of iOS 5.0.1 is finally gone the way of the dogs since developers got a beta of 5.1. So as stated earlier in the master discussion-> I suspect if you are filling up this thread with false post or creating a master set of links to various post that are unreliable you are wasting your time. Press is not going to touch the story due to poor or inaccurate sources which may be links from the master thread. This can include inaccurate information, combination of conflicting post or postings from users which may not own the device. Reputable press organizations have policies that require discloser and strict rules about what is a reliable source for a story. It is clear that many of the post in the master thread, which are links presented here are questionable. 
    Sorry to say that postings taken without any analysis of their totality have been propagated via various sites, for example sites such as http://www.2012federalbudget(dot)com. (Do not visit but I suspect that this is not the 2012 federal-budget site you would expect based on analysis of the records. There are plenty of sites like http://www.2012federalbudget(dot)com propagating questionable post in these threads.) One site for example in the discussion thread used a self signed certificate, the site had a log in to allow users to enter their OpenID. Seems many of these sites are pop and drop drupel configurations.
    So remember this is how the really bad rumor of iOS 5.0.2 got started, the 5.1 memory leak issue, iCloud Issues, call quality, address book, etc.
    Some of the postings have been very comical, I think the latest now is a dropbox issue. Seems that the length of the previous thread has resulted in various app engines of some proxy servers/tools reaching their limits.
    So I would make sure to know the source of any information you link to. Make sure you avoid entering any information to outside links such as OpenID or Apple ID, these are big prize items for anyone with malicious intent.  If you have issues and are a valid user contact APPLE CARE. (Note link is using McAfee Secure Short URL Service, and is https.)

    The original solution still represents a high level of success for users having any battery issues.
    Install 5.0.1 on your iPhone 4s. Some users posting they are still using older versions, bad fake serial numbers, etc.
    Make sure your device can run iOS 5.0.1 and is not altered.
    Make sure you use a new Sim, not some cut down version which many users admit to doing. (Again, worth confirming what people are posting.)
    Reset the device doing a hard reset and software reset.
    Let battery drain and then charge for the full cycle, which is 24 hours.
    I think you will find you will get the battery usage that APPLE has stated for the device.
    Best of luck, stay safe and thanks
