Iphone 5 and IOS 6.0.2 is draining my battery! (new thread)

Question

Well, apparently Apple doesn't want us to talk about this -- They locked the previous forum I had created after 217 posts and 16k views?
I'll assume there is some other Apple Forums rule that I don't know about that would cause them to do that instead of trying to stifle the reporting of this problem?  It was clearly generating many posts that show a correlation between IOS6.0.2 and battery issues.
To summarize... I was having significant WiFi issues on all my apple products (several Iphone 4's and and Ipad2) with 6.0.1 - all the same issues that have been reported on these forums thousands of times.  I was excited to see 6.0.2, hoping it would correct the wifi issues for my iPhone5, at least. Unfortunately, not only did it NOT correct my wifi issues, but now my battery is draining about 5x compared to before.  I can barely get through a day of batterly life with minimal usage whereas before 6.0.2 I was easily able to go 2+ days.
An apple representative called me today (actually he tried very hard to call me for several days.)  I was appreciative of the reachout (saw my other post) and was hopeful they would be willing to help me.  The guys was very nice, but it truly felt like he was reading a script and was more interested in getting information from me.  The only advice he ad for me was to back up my phone and then reset it to factory settings (like new) without using any of my previous apps, mail, etc.  He wanted me to do this "for a day or two" to test it and see if the problem persists.  Then, if the problem is gone, we can work together to restore apps/settings one-by-one until we find why the problem is there.  In other words, they have no idea what is causing this problem, and they want to use my time to help them figure it out. 
Ironically, I was able to watch my battery indicator drop several percentage points while I was on the phone with him for about 20 minutes. 
When he asked if I would do the restore and/or load profile software on my iphone to track my usage, I said no.  I shared with him I'm simply out of time and energy -- I have logged over 40 hours trying to debug these wifi issues (I'm somewhat tech savvy and figured I could just plow my way through to a solution with my router/security settings.)  When I realized that these issues are all IOS driven, and now the battery issues, I find I've had enough.
Maybe I'll go return this Iphone5 and ask for a replacement.  However, I'm also seeing other posts saying that did not solve their problems.
We are talking about wifi and battery life.  This is not new technology. 
If IOS 6.1 doesn't correct these issues, it's probably time to buy an Android.
Please keep posting things directly relevant to BATTERY issues with iPhone5 so that this thread can stay on task and bring to light the correlation between 6.0.2 and the battery.  Maybe Apple will care about their loyal customers, acknowledge the issue, and let us know how much longer we should wait for 6.1 to fix the issue before it's too late and they start losing their fan base.  No information from Apple is only exasperating the problem.

I had the same experience with a new iPhone 5 that I bought  last week. Did not have a chance to measure battery life before the 6.0.2 upgrade installed but I set up my phone exactly like my 4S and immediately started running out of power after short periods. Went to Xmas get together with fully charged 5 and 4S. Heading home the iPhone 5 shut down for low battery and the 4S had 65% power. Both phones had two half phone calls on then and no data usage.
That night I fully charged the iPhone 5 and, without lighting it up, put it on my night table. Next morning I picked it up and looked at battery indicator and I had 42% charge with NO activity!
Tried it again next night and wound up with 37% charge. (Slept longer).
Today I called the carrier and reactivated the 4S.  Took the 5 to Apple Store and they kindly gave me choice of new replacement phone or refund. I took the refund. Uniquely, the Apple Store said it was Verizon CDMA phones that were coming back.
The are other strings on this with temporary solutions, but from my experience with 7 firmware changes on an HTC 4G phone the problem will continue because the solution will be hardware caused. We are in the days where RTM means Rush to Market - not Release To Manufacturing.
I fear the only solution is to either wait for the next model (I did not notice a really major change in performance over the 4S in LTE heavy Seattle area) - or switch to another manufacturer.
It might be useful for these forums to indicate if you have a GSM or CDMA phone to see which have more problems.
