    I've been getting bad battery life, but tolerable. usually 4-5 hours..

     

    but today I am at 29% remaining after 2.5 hours usage and my device is WARM. it's burning through battery at 1% every 1-2minutes.. there is defnintely a runaway process. if i power cycle the device and charge it up it will be *ok* again.

    Hey Handsfull how is your battery life using or turning on bluetooth? Even if you don't use it can you turn it on and get back to us with your numbers please? I notice using bluetooth to stream music to an external speaker that not only gets my phone warm but drains battery fast. But when leaving bluetooth off gives me numbers somewhat close to yours around 9hrs on average.

     

    Thanks!

    Bluetooth, as long as it's turned on for me drains battery like crazy.. doesn't matter if i am using bluetooth or not though.

    Don't know it it has been mentioned before (this thread is sooooo long!!), but here's something to try: http://insanelyi.com/blog/6/entry-707-boost-battery-life-of-iphone-on-ios-6-by-t urning-off-tracking/

    @Ramone

     

     

    I never use bluetooth so it would take another day to test.  Bluetooth is a difficult one to gauge because it depends upon how much info/how heavily your tasking the cpu to push/receive a BT signal.  IMO, it would be safe to assume a 25% additional reduction on battery life ACTIVELY using BT (ie, streaming music to a player).

     

    Apple just called me and left a voicemail, I just called and return voicemail.  I have a plethora of data if they want it.  As much time as I sunk into this beta testing, I'm asking for a lightning cable/adapter- LOL - I need one and can't even buy one - they still aren't available.

     

     

    @am94

     

     

    No one knows for sure yet whether it's hardware OR software.  I'm swaying towards software, but like I stated earlier....I did the EXACT same thing to both of my phones...one worked, the other didn't.  On the other hand, people with 4s and 4's are reporting identical issues upgrading to iOS6.  Could be iOS6 entirely, OR a combination of both OS and hardware mixed in.

    Yeah @handsfull if you could just even have it turned on not even necessarily in use but just to see since your phone seems to be working at its best what kind of life u will get after a full day of having it on. Also were you on. Wireless connection most your days on that picture you gave us of your battery life? Because I notice on being just on AT&T's 4G HSPA with LTE turned off because it's not available in my area yet it seems to drain more as well. Curious to know if you were mostly using your phone while on a wifi connection or what the ratio was between wifi use and cellular use? Thanks Again!

    Hey Handsfull - how much of this 11+ hours was listening to music. Also, was any of this in airplane mode with only wifi on?

  • atlantis79 Calculating status...

    I have finally figured out what is killing my battery life... Poor 3G signal.

     

    In my house and at my work my carrier (UK three) has appaling signal (1-2 bars if I am lucky, none if I am not). When I am out and around in town where the signal is much stronger the battery life is as you would expect 1% every 5 minutes of useage and that is with plenty of stuff turned on. When I am at home when I have wifi the battery drops faster than when out but still okish. When I am at work where I have neither WiFi nor good 3G signal I lose battery life like there is no tomorrow....

     

    To test the theory I switched off my WiFi in the house for a few hours. I lost 25% battery in that period while not using my phone...

     

    Now I hope that that is software related and software wakes the radio to often when it has weak signal because of too many failures to connect or something like that and not deffective radio chips cause I really do not want to go through exchanging another phone.

     

    I love my iPhone other than the stupid erratic battery life. Apple please fix this!!!!

    Ramone and cros:

     

    Had Bluetooth on since my last post (nothing connected), no discernible difference on battery consumption.

    I am taking my pictures at home on my wifi.  I am on wifi during the workday VERY intermittently...say....less than 10%.   Total wifi use represented in my pic? About 20% of the total time cause I was playing with it in bed before going to sleep last night.  I don't turn any notifications off, or any location services off....and I won't....it's why I purchased the phone in the first place, to use. ;)

     

    I never put my phone in airplane mode.

    Atlantis:

     

    If this bug is iOS related....apple can help. If its hardware related, only you can go get a replacement and remedy your problem.

     

    I just got off the phone with Apple, they actually called me..... My opinion is that there is both a hardware issue AND a software issue....for many reasons too numerous to list.

     

    If you can get a replacement...do it.

    Handsfull. Do you think had you done a full factory reset on your 1st iphone 5 then followed your steps in setting it up as a new phone through just icloud sync that your original phone would have worked fine as well?

    @ Handsfull, TY, but any music listening included in that 11+ hours, or just tinkering, surfing, checking email, wifi, 3G LTE surfing etc? The reason I ask is, I can get about 15 hours if I was just playing music, so if you were listening, your numbers might be higher than normal

    @ramone

     

     

    You should look back into this thread, there is AlOT of info myself and others have posted. 

     

    Yes, I have done every single possible step to eliminate the problem on my previous iPhone 5.  That includes full restore, restore in DFU mode, restore as a backup, set up as a new iPhone.  Multiple times.

     

    Signal strength of LTE/data is not the cause of this battery drain. That I can promise you.

    Lol I have been following and keeping up on this Thread religiously, unfortunately. My bad on repeating something thats already been posted. But it seems if thats the case that there is in fact a hardware issue and if thats the case, theres no way apple comes out with ios6 update before launch day purchasers 30day money back guarantee, and if it is in fact a hardware issue on some units theres no way Apple will admit that to the public. Were basically screwed either way. Time to say my piece. Apple I've been loyal since day one of your mobile products, ie (iphones, and ipads all generations) it's a shame that we the consumer have to succumb to being beta testing sheep of your product. I hope you are reading these posts in this thread and I hope you make this right or I am sure day by day as this thread grows and this problem doesn't get fixed, the competition will start to get a look from the smart ones who have caught on to your corporate greed and no longer caring about the consumer. I hope I can eat my words soon to come back here and post that Apple has made this all right. Thats it I'm done.
