***THIS WORKS*** Battery-gate can be solved! Until a formal fix is released, try this:
Looking at cloud based connection and LTE will dramatically affect battery life. Constant push setting on Mail, and really high screen brightness also eats up juice. The fix that worked and helped me achieve comparable battery performance equal to that of the competitions phone- is the DFI restore and then selecting "set up as a new iphone". This and setting mail to fetch or manual fetch immediately solved the dramatic drop in battery power drain. Confirmed that it lasted from 7:40am to 11pm after the changes, and that was with average texting, siri use, lte on full time, and google searches, numerous texts and phone calls during this time. This at very least helps us get a full day of usage in, and a full work day with plenty of use as well.
Updates done over wifi or 3/4 G /LTE will also eat up juice. Where we used to sync with the computer via USB now it is an OPTION to do these updates without being tethered to the computer. Depending on how much, expect this to add to the drain if its being done often. You can disable these features to conserve.
Battery caliberation is also wise. Personally its my perference to charge for 8-9 hrs, then let the battery use itself up completely prior to a subsequent charge... unless absolutely necessary.
Tests have also been done (iOS 6.0.1) on my iPad 3, and iPhone 4... neither of them appear to be dramatically affected with the battery power drain as noticable as the iPhone 5. The iPhone 4 appears to hold its charge in the same mannor as it always did, and no special methods were used to update them, as they were both updated using the wireless update method.
There are also specific apps that have known issues with iOS 6.0(.1.) Looking through google and the forums here will help you isolate problematic apps that are having issues. One thing people here need to keep in mind is that Android based phones are no better. As a true apple enthusiast, (I like all tech and not just Apple mind you)- it is with personal experience that showed me sammy also has these issues. Hi powered options mean high power consumption. Other competitiors have these same issues documented consistently. Juice defender for android does essentially the same thing as what toggling the settings manually in iOS does. The idea being "be creative" with your settings, and taylor the specs to your needs. More notifications and endless alerts can add up!
IMHO Apple has responded to the endless waves of customization settings that some people have whined endlessly about not having, with, ehm, cusomization settings. It would seem that those not used to this "not automatic anymore" mentality are the ones most severely bothered by this battery-gate issue.
As time goes on one thing is clear. Its still a phone people. Made imperfect by us imperfect humans.
It will never be a desktop, professional camera, butler, or personal assistant, although it sure comes close!
We all know the programmers at HQ are working hard to try to make everyone happy. Of course thats asking alot.
Watching the folks at Apple since the first Apple ][ computer, I can tell you this. They are not done yet.
Give it time and be patient. Even god need a week. So far the 5 is still by far the best solution out there.
If you give these suggestions a try, Im certain unless its a hardware issue, the above DOES WORK.
Ensure your contacts are saved to sim, and all notes, caladars,apps, music etc. are in the cloud or on your mac,pc & itunes.
One thing we all know, is that Apple will stand behind its products with either free software updates we as a community can all enjoy AS THEY GET RELEASED, (not one brand at a time lol) and a replacement device should the hardware ever fail. **** they even help you if you do the damage. Good luck getting the competition to do that!!!
Hope this helps.
