I've had stellar battery life since upgrading. 16 hours standby and 5 hours usage and still have 25-30% left
I wish. I've been home with the flu for a week and haven't been touching my phone.
When I wake up and take it off the charger, 100%. When I got to bed it's close to 20%. At most, it's rang and taken a voice voice mails or received a few texts. Prior to IOS 5, it would have been at like 97% if I didn't use it all day.

To people blaming iCloud... only if you had automatic downloads enabled and were having one hell of a shopping spree on a computer somewhere. When you upgraded to IOS, your devices had to sync and back up, so you didn't start off fragmented.
The over night back up ONLY occurs if the phone is connected to a power charger. So iCloud really shouldn't be running at all unless you manually enabled it, or bought something on a mac, pc, or other IOS device and its being pushed down.

Perhaps Jobs should have "cracked" this problem before giving up the ghost.
That was in terrible taste.
And Steve Jobs was also the man that told tens of millions of people they were holding their phones wrong, and threw a press conference to do so.
RIP Steve. You were brilliant, but the "you're holding your phone wrong," and "people don't read," will be my favorite of you less brilliant moments. And everyones allowed a few of those.
