Battery drain after IOS 6 update

Question

I and my 3 family members and two fellow employees have all noticed that since upgrading to IOS 6 on our cellphones we have had the following issues;
1. Massive battery drain
2. Battery heat-up during recharge with the phone on but not being used.
3. Lost data
With the phone on and not being used - the charge level drops much faster.  I used to go the whole day on one charge and recharge at 10 pm with 30 - 40% of the charge left.  Since the IOS 6 upgrade I'm recharging at 4pm with a 10% charge remaining on the phone .
Also -  recharging the phone while it is on (but not in use) causes  noticible battery heat-up.
Again - this was not the case for any of the 6 of us prior to downloading IOS 6
My conclusion is that there are aspects of this new operating system that use a lot more battery juice than the previous IOS 5.1.1
This significantly increased demand on the battery is showing up as much less operating time and battery heat-up during recharging.
Anybody else experiencing these issues ?

Answer 1

Got onto Apple Teckies yesterday & spent about 1.5 hours on the phone with a very helpfull bloke
that went through everything.
At this stage my phone has been reinstalled with iOS 6 as a New Phone (Like a test mode) so NONE
of my APP's or Settings only my Contacts from iCloud (As a New phone would come out of the box).
... From the time we finished uploading the iOS 6 softwear untill now my phone has only used 40%
battery so it's looking good.
If this works I then have to conect my phone with my iTunes & Reinstall from my Back Up to get all
My App's & Settings back.
... Then we will see if it has worked.
... Will let you all know what happens in the next 48 Hours.
