I re-activated my Droid X which gets at least 50% better battery life than my 4S gets and that is without turning off any notifications or locations. I think the 4S is an excellent phone and reserve the right to commit to it again once I have decided if the newest batch of Android phones coming out in November are going to be better or not. Comments about how an Android phone is much worse in battery life is just plain foolishness. Some Android phones have poor battery life, and those that do have the removable battery option. I was able to turn off notifications and location to get battery life for one typical day. If you plan on keeping the 4S, plan on keeping a charging source near by. If I buy it back I know I will.
