Hey Robin,
I too have seen improvement since doing a hard resent and then letting my battery totally die. I still don't have as much battery power as I used to, and I never get to the 10% indicator or 5% indicator like I did with IOS 7.01,2 and 3. After the 20%, it dies a few minutes after. There is no way this many people around the country, all of a sudden, have bad batteries. Yes, the 4s is old. I just think apple folks sat in a board room and discussed how this new upgrade would kill batteries on the 4s, and that they'd have a convenient excuse to say "hey, your battery's almost 2 years old, you need a new one, we can do that for $100. If that happened, it's fraud, and heads need to roll. Regardless, a fix needs to be included in 7.05 or I'm done with apple. They are doing the same thing to both of my macbooks. My macbook pro gets worse with every update. I have tons of room on it, plenty of ram, and only use the internet and a few applications, but it keeps getting slower and slower. There have been no significant advancements in computer technology for several years. This is apparently how businesses have to get by now. Instead of building durable products that stand the test of time, they have to find ways to make them fail so they have to be replaced. Creating more waste. Very disappointing.
