    Ran the battery down to zero. Did a complete reset, deleted Facebook and set it up with what you see below.



    32gb iPhone Black

    Carrier: Sprint

    WIFI: off

    BluTh: Off

    B/G Apps: None

    Pass word lock: off

    Notifications: Off

    Activity: Stand by

    Battery Charge 100%/13-3/4 Hrs

    Getting a little less than 14 hours with the phone doing practically nothing. Tonight I'll run Music till the battery runs out. I'll also try to measure the surface temp before and after.

    I ran a log and posted some of the results on this thread. Made an appointment at the Genius Bar and took a spreadsheet with a 4-day log. We backed up the phone, wiped the phone and then restored it.Took about 15-20 minutes. My numbers are significantly better.

    To be clear regarding the above post, I had asked the Genius to wipe the phone and to reset it as though it was right out of the box.

    Ok,  I got my iPhone 4S to get better battery life.  I did all the suggestions listed above... (AGAIN)


    i.e. Turn off Location Services for TimeZone, And Calendar Notifications.


    I Also turned off the STOCK widget on the notifications pulldown. Run mybattery down till the phone turned off, then Fully Charged it and then Did a HARD RESET. <--- MOST IMPORTANT {I believe to make changes take effect} [No need to do a Restore only a Hard Reset]


    Last night I charged it up and then unplugged it at 8pm then When I woke this morning at 6 I checked it it still has 99% !!! yea! (last time I Unpluged it overnight fully charged and then woke up it was at 55%)

    Also I am using it today normally and I am still at 98%!  (Made 2 Phone calls 3-4 mins each) checked 3 emails, and surfed the web for about 5 mins) and its 11am!  Orginally I would have been Down at around 80% or Less!


    So To ReCap:

    I turned off the Stock Widget, Turned off Location Services for TimeZone, Turned Off Calendar Notifications & Run the Battery down to Empty, Did A Hard Reset And Its Dramaticly Improved the Battery Life!


    I hope his helps afew iPhone owners till Apple fixes the Bug/Bugs in ios5/iCloud.


    Good Luck!

    My experience is that turning off Siri vastly increases battery life.

    So would turning the phone off. Most of the fixes talk about truncating it's functionality and features.  From most of the posts I've read there is no one magic bullet that makes the phone run as advertised. I've gotten used to the phone being tethered to a charger and I'll just wait for 5.01 or whatever.

    I deleted my Exchange account, rebooted, and added it back. I leave EVERYTHING on now and my battery life is much better than my 3GS ever was.

    Just to add some further observations. My wife and I have the same phones: 4s/black/32 gb/ Sprint. After the 5.01 patch are phones are draining faster, in fact my wife's phone takes longer to charge. I've run tests simultaneously with both phones starting at fully discharged batteries to 100% charged. I've tested the phones straight out with no background apps, wifi, Bluetooth, locations disabled, and ran both phones full tilt with non-stop Rhapsody playing non-stop.  I've lurked on other threads and have tried the suggested settings and workarounds. Our workaround is to keep the phones on standby, locked, and tethered to mobile and house hold chargers. Patiently waiting for 5.02.

    Did you delete Exchange accounts, reboot, and add them back?


    If you restore the phone as NEW, do not install any apps and do not create any email accounts or backup or sync with iCloud does the phone still drain rapidly? If so I would return the phone as it is defective.

  • Mistermurella Calculating status...

    Hi there, I have been suffering the same battery drain issues and last night I found a post on these forums that involves shutting down Siri and then hard resetting the phone to turn off the I.R sensor that is visible above the earpiece speaker through the lens of another camera. All you see is a purplish light and I figure that's it because after hard reset the light is off and I have 81% battery left after approx 11 hrs without much use. Hope this helps, I have turned iCloud and everything else back on again without incident.
