Sorry all,
I'm glad that you all have replied with your years of experience with Apple phones and tablets. Obviously, without having the 4 and 4s, I'm ignorant to the EXCESSIVE drain. I just know that I'm always annoyed with the continuously INCREASING battery drain of a two year old iPhone and can't wait for the next one to come out. I DO agree that they need to do something if this OS update is EGREGIOUSLY draining batteries. There is always inherent drain whenever new iOS come out. I actually do bellieve that Apple and other companies knowingly make these updates use more battery life so they can move their product. But from all these reports, this drain sounds like it's quite excessive and a gaffe by Apple that they are not yet willing to admit to.
The whole iPad thing is also inexcusable because I don't think anybody has the "new every two" option on iPads. They are too expensive to update that often.
I guess it's never an issue with me with my iPhones because with every upgrade I make a PROFIT by selling my 2-year-old phone on ebay for 50% greater than what I pay for my latest edition iPhone (with my new-every-two AT&T contract). I sold my 4s for $300 and some change right when the 5s came out and bought the 5s for $200 and some change = 50% profit. BUT, I was only experiencing the NORMAL increased drain with my 4s when iOS 7.0 came out.
