Not specifically in response to your post, but just to try to add an element of rationality to this discussion:
I am sure that all of us would like to have a smartphone that only needs to be charged once a week, and it would be nice if that recharge took only 10 minutes or so. Sadly, this is NOT a reflection of the reality of the current state of battery technology. Manufacturers must walk a fine line between a heavy, bulky, product, and one with shorter battery life. So, they design for a battery that is small, light, and has the best charge density that they can put in the device within the budget for the cost of the device. Users just want the phone battery to last forever, and only to charge it 'now and then. The current reality is that if you want all the nice features, you pay with battery charging time. If you want the battery to last a long time (critical with iPhones non-replaceable batteries), then you can't charge them too fast, and you can't 'deep discharge' them. So, where are we?
It seems that some 4S phones have an electrical problem. Clues are that they make noise (staticy noise) during charging, and get hot in use. With the ultra-tight space constraints within the iPhone 4S, such things can happen.
I see complaints that the phone really needs to be charged daily, or more than once a day, in heavy use. OK, how many of us have a lifestyle where this isn't feasible? I have two computers, and both have charge/data cords plugged in, ready to charge my phone. I have a car charger, so I can recharge in my car.. If I worked (I'm retired), then I am sure I could find either a USB port, or wall outlet around to keep my phone charging during working hours. For those who are 'out and about' all day, and really can't recharge, there are add-on cases with alternative batteries that will surely power their phones all day, even with heavy use.
Yes, there IS a problem with some phones, and Apple should address this. Yes, there are issues that are more than likely associated with IOS 5 software (it's new, and they are working on solutions).
We all need to deal with this in a more rational manner, and be just a bit patient. I strongly suspect that for most users with a definable battery issue, the problem is either a real electrical fault (and Apple will replace the phone), or expectations that exceed current technological/economic realities.
And, please try to be nice. Bashing Apple won't help, and flaming other posters won't either.
