    Hi, i thought i'd try to get this back on track. Iv had similar problems with my 4S since i got it in november and iv tried everything to try to fix it. First off i know my problem isnt as bad as many other people on here but i found after charging it to 100% and leaving it other night it would drop 30% in 8hrs. So apple were happy to replace it and called it a hardware fault. I tested the new phone after restoring from icloud back up and it was fine all the settings im used to having on and it dropped 1% over 8hrs sleep. So i forgot about it untill a few weeks ago i tested it again to find it dropped 20% over night. So i had it replaced and this time set up as new and havnt yet activated icloud and i havnt no apps installed. Iv been testing it my self to try to isolate the problem. Each night i charged the phone to 100% and tried a different setting to see the standby drain.

     

    Setting                                              Drain                    Total standby possible(hrs)

    ____________________________________________________________________

     

    No settings active                               <1%                                     >800hrs

     

    Bluetooth only                                    <3%                                       266hrs

     

    Wifi only (ask to join on and off)          >12%                                     <66Hrs

     

    Wifi only (no network connected).        <1%                                      >800hrs

     

    Siri only                                              <1%                                      >800Hrs

     

    Data (3G) only                                    <1%                                      >800Hrs

     

    Location services (all services on)         <1%                                     >800Hrs

     

    Wifi on plus all options                        >15%                                     <53Hrs

     

    3g data on plus all options                   <1%                                       >800Hrs

     

    Wifi &amp; all options(no blue tooth)          >14%                                       <57Hrs

     

    (Dnt take the possible standby too strictly i havnt tested it for 800hrs but i just worked it out from 8hrs usage.)

     

    The last test here, i did just last night and this time i checked the usage stats, After 10 hrs off charge and 2 hrs since i woke up my usage is 10hrs standby and 5hrs usage. It should show 2hrs usage max. As you can see from the tests wifi is a big issue and i dont understand why

     

    So thats it. If any1 wants me to try a setting or clarify any of the settings iv used then just ask ill keep testing untill i get IOS6 and then im going to do it all over again!

    Just reporting back in that I did resort to the "restore as new phone" solution, and that solved my battery drain issue.  Now my phone's battery is back to the performance levels that it had when I first got it.  Odd thing is, along the way, I had actually deleted ALL of the third party apps on my iPhone, trying to determine which one might be hung up and utilizing the battery so heavily. So since the phone was so stripped down, I was mistakenly thinking that a "restore as new" would be overkill.  But no...it was just what the doctor ordered.  Thanks to all of you who have suggested it along the way.

    I was just complaining to my buddy that i thought my battery may be a bad one (after only like 1.5 weeks of having it lol) because i charged it monday night into tuesday morning, and had a game going on and some texts, then woke up, unplugged it, drove to work and checked my battery on the way in (20 mins after i unplugged it), and it had dropped to 99% (had stayed 100% for a couple hours then drops 1% every 15-20 mins depending on usage when i first got it) but then i charged it when it reached about 50-60% yesterday, unplugged it when it hit 100% send 2-3 messages, and haven't used it all night, i woke up and at work approx 16+ hours later after unplugging the charger and the battery is now at 85%. This is my first apple device period, so i'm new to the way things are with the OS and battery life and such, i had an Optimus S before. Am i just talking outta my arse or do i havea reason to complain? If i use the phone like normal, i'll charge it maybe 2x a day (normal being about 20+ msg, check email 5x a day, play a game for about 15-20 minutes, and check facebook about 5x a day)

    You tried what?

    Turning off everything, even the phone, and your battery life is still bad?

    If you are not on actually on a call or using data, put it into airplane mode.

     

    That would mean that you wouldn't be able to receive calls/ Kind of defeats the object of a phone I would have thought!

    Some people use a phone for THEIR convenience, not the convenience of others.  And the iPhone is MUCH more than just a phone.  Shutting off the radios (airplane mode) leaves most other features available.

    Tried what you mentioned earlier.

     

    "Something is running in the background.

    To quit all apps and remove them from the Recently used tray...

    Double tap Home.

    Tap and hold any icon in the Recently used apps tray at bottom.

    Tap the red minus sign on the corner of all apps.

    You should generally do this a few times a week."

     

    Yes, after I turnd off the phone and turn again, nothing change, the battery life remains awful. But there is something that I noticed. The battery stays on 100% for relatively long but after it starts drain very fast, so from 100% to 99% it is okay, but after from 99% to 98%->97%...etc it drains so much, I lose 10 percent in half an hout use.

    They all seem to do that - stay at 100% for a long time - it seems to be the way Li-Ion batteries work. It's especially noticeable if you leave the phone on charge for a while after it's reached 100%

     

    Get the System Activity Monitor app. It's £0.69 ($0.99 I guess) but it's money well spent. My phone suddenly started draining a lot faster and I couldn't figure it out. This app - which is very similar to the Activity Monitor in OS X - found the culprit. In my case, it was Skype.

     

    Skype has a setting called Go Offline which, by default, is set to Never which means that it is always running in the background listening for incoming calls and means that it starts automatically so rebooting the phone makes no difference. I set it to 30 mins and battery life went back to what it was

    The only time I find that the battery  on my iphone is used at a greater rate is when I am out of town.  The phone seems to be always searching for a tower or wi-fi and eats the battery.  I always shut down and reboot when in another city or area.  That helps a lot.  I have had my phone go almost dead overnight if I don't reboot to find the nearest network.  I don't know if that is BS or real but seems to work for me. Someone tell me the truth.  Thanks

    I think this is the normal function.  As you move around, the phone must keep updating its cell connection, and searching for a new one.  This takes battery power.  You can minimize this by turning wi-fi off until you need it so it doesn't have to keep trying to find a wi-fi connection too.

    Cant believe we are still here after a year.

    My iPhone 4S battery life after iOS6 update via iTunes (not OTA) has been really good. After one day of usage (iOS 6 was released for about 26.5 hours thus far), it's still hovering around 40%. Much better than iOS5.

    As I write this post I am upgrading to iOS 6 software.  I haven't used my 4S much today and it is at 88% and I last charged it last night.  I expect a lot of posts given updates on battery life with iOS 6 software.

    Howdy!

     

    I guess trading better battery life for less stellar maps and bluetooth streaming issues is reasonable - and i don't mean that in a sarcastic way. I think it's more prudent to stay off updates though until they have been properly tested in the wild...

     

    Good luck!
