Perhaps I'm not understanding what you mean by standby but when i phone is sitting idle it's still connected to the network. it's not in a hibernation mode that disconnects itself from all network services. If that happened it would surely use less power but you also wouldn't get calls, SMS, emails, iMessages, or any push messages to the device.
i don't know but prior to iOS 6.0.2 when my phone is in standby mode and the moment i switch on the screen it shows that it is connected on EDGE even though i'm sitting at home very near to wifi and after 2-3 seconds wifi sign is back on. it always works the same for my iPads and iPhones from the beginning.
after iOS 6.0.2 even though my phone is on standby mode for a longer period and when i switch on the screen it shows it is connected to wifi.
so my understanding is that this is the main reason of battery drainage which people (including me) are complaining about the iPhone 5 iOS 6.0.2
although my battery drainage problem is nowhere near the way people are complaining on apple's forums that their battery is going down every hour about 20% or something. mine is affected overall about down to 10-15% from full charge.
i hope i made it clear this time.
