I understand that my chances of having issues are very slim. But articles like the one below make me nervous because if i update and have issues, Apple doesnt let me downgrade, meaning we would be stuck with crappy battery life and literally no way to fix it. Not a position I want to be in. I understand that the internet can blow things way out of portortion, but still.

I understand that article refers to 6.0, but most of what i have read has said that people with battery issues havent seen it get better with 6.1 Thats why i was hoping to see a statistic of those affected. I just would hate to pull the trigger and have her battery die on her every afternoon. Just because 300 million are running iOS 6 doesnt mean 300 million are running it issue free. Any amount of them could be having trouble, but you would never know, because thanks to Apple, you CANT downgrade.
