    Definitely a crock being I called Apple Care yesterday... twice!


    I'm at 1 hr 30 min use, 2 hr 30 min Stand by and I'm at 89%. Not too far off from Chrisfromgastonia....


    Does anyone have a link to DFU for dummies? I've seen how to put it in DFU mode but I'm getting mixed instructions on what to do from there... I see  a few options with no explanation... just click restore or I see shift + restore or  ctl+alt+restore. 


    I'm pretty nervous about doing this alone... I don't want to screw something up!  Do you think apple would help walk me through it?

    I tried the DFU reboot and setup as new phone with no real change in battery performance.


    After a call to Apple, I had my phone replaced yesterday.  The "genius" told me to restore from icloud and try it out.  There has been no change, my battery still drains like crazy.  If I put the phone in airplane mode it keeps a charge, it sat in airplane mode for 5 hours today with only droping 1%.


    Since the phone can hold a charge while in airplane mode, and both my orginal phone and replacement phone exhibit the same behavior I'm guessing this HAS to be a software issue. 


    I'm located in a city with LTE, but my office building has a steel roof that no cell signal gets through.  We have a 3G repeater that let's the "4G" signal through but not the "LTE" frequencies.  At home, my cell reception is terrible and I connect to a MicroCell from AT&T. 


    I'm guessing what is happening is the phone is boosting the radio to try and catch a LTE signal and continues to do so until the battery dies.  I can feel a slightly warmer area on the back of the phone near the apple logo.


    My wife has a 4S running iOS6 that doesn't exhibit any of these battery problems.  I'm guessing there is some thing chewing up battery in iOS6 with relation to the cell radios.


    My next tests will invovle turning on resources one by one.


    1. Test in airplane mode <- done seems to work

    2. test with "use cellular data" off

    3. test with "lte off"

    4. turn on location services

    5. turn on icloud

    6. turn on push email

    Just clicking restore, will download the FW from Apple server. Clicking Shift + Restore will allow you to select the FW from your computer, if you already have that file.

    I was draining 20% of my battery in 30 minutes on my new iphone 5.


    I restored my iphone 5 from the cloud originally, so the TROT NIXON method wasn't going to work for me.  I DID try to turn safari syncing off and deleted podcasts (some were stuck downloading) and that pretty much fixed my issue.  Still a problem though - Apple REALLY needs to release a fix.

  • ninjaeclipse Level 1 Level 1

    I think Apple is trying to fix it. They are troubleshooting it just like we are, trying all kinds of ways. They are stumped and don't really know the cause...they in the same boat.

  • Joe Gramm Level 5 Level 5

    Just adding my name to list with bad battery performance.

  • chrisfromgastonia Level 5 Level 5

    No apple will not help you for it is an unsupported process by apple. I can tell you what to do or you can google it. Which system do you use, Mac or PC?

  • Joneso Level 1 Level 1

    My battery to is draining faster than my 2 year old iPhone 4 ,and trying to connect to wifi is unbelievable .

    I spoke with orange today ,they said they had no reported problems ,

    The phone won't even let me restore from back up from my iPhone 4 ,

    Not impressed .

  • mfritter Level 1 Level 1

    So is there really a difference the between doing a normal restore by connecting it to iTunes and selecting restore (which is what I did)  VS a DFU restore? 


    Don't they both wipe it clean and get the latest firmware form the Apple Server?


    Sorry for a million questions... I just don't want to do this again if I don't have to... and thanks again! Much appreciation!

  • chrisfromgastonia Level 5 Level 5

    Yes there is. DFU does a complete wipe and then restore from icloud backup. but make sure you do a fresh icloud backup first before you start.

  • Smvk Level 1 Level 1

    Well we all better start reporting the issue then

  • mfritter Level 1 Level 1

    Ok thanks... I'll try it then.


    The guys at apple backed up stuff at iCloud the first day I got the phone but haven't used it since and turned it off so I don't care to use it if I can avoid it. I'm on a PC that doesn't support it so i dont' really know if I can even use it effectively.  I have my apps on itunes and I use an exchange server for my contacts and calendar and I haven't taken pics yet so could care less about them.


    Can I do the DFU restore to new? Or do I need the iCloud back up? I googled DFU and I see how to get it to enter DFU mode... but then I don't see much intruction after that.


    Sounds like I just click restore after that and I should be ok? 

  • chrisfromgastonia Level 5 Level 5

    You have to connect to itunes then put in DFU, then when the box pops up that itunes recognizes a phone to be restored then you have to hit shift command and click on restore in itunes ( phone still connected ) then choose ios 6 restore from the pop up. once it finishes the reload it will be like a new phone out of box , then follow the prompts and do a restore from icloud backup. But make sure you turn all icloud backup items on for icloud, contacts pics, etc. and do a new icloud back up before you start the DFU process..

  • dyeylet Level 1 Level 1

    I have posted before I have put my AT&Tiphone 5 64 GB  into DFU mode and just used it for a day without contacts or anything turned on . Meaning I left everything as default after the restore except for turning the wifi off My phone only lasted for 4 hrs 30 minutes  usuage I browsed the internet called three times for about 11 minutes each call then checked cnn news and left phone in standby. This is my second Iphone 5  64 gig from AT&T same battery drainage battery discharges just by looking at the phone while its on.!!

  • ninjaeclipse Level 1 Level 1

    A day of use after DFU. From 99% to 21%

    Only read emails and browse a few pages.

    Display set at 70% then 100% during lunch time.

    Didn't talk on phone. No texting. WiFi on. Notifications off.


    So DFU didn't fix it.

    Not good.
