    I downloaded WhatsApp long ago on my iPhone4 but didn't use it as soon as the App asked permission to send ALL of my contacts to their server.  That was a BIG, BIG no, no, so, I never even used it after purchasing it.

    I read your post. I got this iphone as a gift last sunday with IOS 6.0.2, I have no idea how to get it to 6.0.1 or anything since this is my first apple device. I guess my only solution is to wait until apple releases a fix... maybe 6.0.3. Thanks for your assistance so far. Although the battery issues is frustratig, Its the best smartphone i've ever owned, having used samsung galaxy and blackberry before. cheers and happy new year everyone.

    Apple will release a new update in mid-January. iOS 6.1.

     

    I've read the developer beta reviews and most of them say the battery issue is fixed. So hang on my friend for another 2-3 weeks.

    For me it's all about when I'm not on wifi. I'm getting great numbers like 20hrs stand  5 hrs usage at 50 percent.  This was on dri sat and sun am. I goto football game yesterday and from 10 am to 6 pm with about 1 hr 45 min usage all on lte I was down to 50 percent

    It looks like after some cycles, the battery started to behave differently, not the right way though.

     

    Yesterday, before going to sleep, I charged my iP5 to 100% and let it stand by.

    This morning, when I woke up, it was impressively still at 100%, for the first time.

     

    Unfortunately, the weird behavior of the battery continues, and my case is just like with cvea. Just reading the recent post in this discussion, bam, 3% drain. If I continue using it, I can watch the percentage going down very fast.

     

    The most strange thing is the Usage report showing THE SAME AMOUNT for Usage and Stand by times!

    Look at my last post at page 65 for some screenshots.

     

    Reading other discussions, people managed to only really fix it only downgrading to 6.0.1, so it's clearly a bug in iOS, not a matter of switching preferences. I hope Apple releases the next iteration of iOS soon, or else I'll also downgrade. =(

    I might have found evidence that supports some of the online tech gurus stating 6.0.2 has increased WiFi checking activity.  I installed a data usage monitor app yesterday evening.  I only used cell service, at one point turning off LTE and having it strictly use 3G.  Several hours later the app correctly stated cell usage, and it also stated I used 11 MB of WiFi, even though the WiFi feature was tuned off in settings.  So, either this app is garbage or iOS 6.0.2 is jail breaking the WiFi settings and creating  WiFi activity.   If that is the case then should the Federal Aviation Administration (FAA) be aware of this for the security of some technically fragile aircraft?

     

    If iOS 6.0.2 is leaking RF (radio frequency) then this is a major issue.

    I propose the FAA request an increase in their budget to employ one programmer to create Apps for all mobile communication devices to monitor and store data for all radio frequency usage, times and locations.  Then sell it for free.  Having Washington pass a law to make it mandatory on all operating systems would be an added bonus, for comparison sakes as well.

     

    I moved my AM/FM Clock radio to the other side of the bedroom (so I could sleep in peace) because of the iPhone 5's RF leakage made the clock radio's speaker repeatedly blare the first night I had it!

    I had a smiliar experience described by most here with the battery on my brand new iPhone 5 draining very fast.  On most days during the first two weeks, the percentage remaining would be around 50% or less, by noon.  Compared to the iphone 4 and 3Gs, this was far worse and made the phone almost unusable.  In an attempt to fix it, I ran through complete discharge cycles, closed all apps, restarted the phone, and did several restores both as a new device, from iCloud, as well as a reset and a firmware restore.  In all cases, the issue did not go away, and the battery continued to drain about 20-30% faster on average than my previous phones.  I use many of the features that users mentioned turning off (Bluetooth, push email, some location based services, and LTE when I'm in an area that has it), so turning them off isn't an option (and should be necessary to get comperable battery life to previous version of the phone).

     

    After exhausting every option suggested on various forums, I finally chalked it up to a hardware issue and exchanged the phone within Best Buy's 30 return.  Having used the replacement phone for a week now, I can confirm that it was indeed a hardware issue with the old phone as I can go an easy 12 hours or more on a charge with all services turned on and moderate GPS, Podcast, and Internet radio streaming used.  For those of you experiencing extremely fast battery drainage which is worse than your previous iphones, I would exchange the phone if you are within the retail stores return policy window.

    I've seen an iPhone 5 on display and it had many contacts on the phone from the same city.  I wonder if it was a customer phone that was replaced with a new phone?

     

    Wiping the iPhone (General>Reset>Erase All Content and Settings) before handing the phone over for a replacement is the least a person should do.  If I had to turn in an iPhone then I would not rely on Apple's TRIM, Garbage Collection or Erase features for the SSD.  I would go through a process that replaces existing data with other data (not the HDD way, not possible).  But, there is the serial number issue that could possibly pull up iCloud synching.  Perhaps it might be written that it's not possible with the iCloud, but the same was said about the fictitous virus issue with Apple's computers years ago.

    mysterious battery drain problem started yesterday- january 1, 2013.  Prior to that, made it through a day of normal use, some talk time and some browsing with ~30% charge left (with WIFI and Bluetooth on all day).  Starting yesterday, the phone drains in a couple of hours.  Recharge takes very short time but drains just as fast, so not getting a full charge, even though indicator shows 100%.  The phone feels warm to touch as though processor is running, but all apps closed, Push turned off, no iCloud sync, brightness down, etc.  Reset Network settings per another post on here.  No change.

    At a loss.

     

    Useless device at this point if it can't even hold a charge for 3 hours on standby!!!

    Getting close to exchanging it if this continues.

    I received Apple advice today to let it drain completely then recharge to 100%, then let it drain again completely then recharge to 100%.

     

    Try disabling Find My iPhone feature, for now.

    I think everyone has a different source of battery drain problems, I decided to uninstall whatsapp Sunday and I have not charge my battery since, I am now at 15%, I made calls, played games, listen to music etc. on any given day with whatsapp up and running, I had to charge my phone within 8hrs of use, I am not saying that apple doesn't need to work on the battery drain problem but the answer  may not be be the same for everyone until apple says something official. for me, my problem was whatsapp, it may be something else for you. I read some articles on ios 6 and people are having battery problems since the newest update but apple is saying its not a lot of people as compared to previous years, ofc they not gonna just come out and say its a bug yet, but anyway, for those who have whatsapp installed, try uninstalling it and monitor the battery use and report back... until the rollout of ios 6.1...good luck everyone
