This is where you aren't paying attention..........
1. I have most everything turned on.
2. I can go nearly 2 days on a full charge, which is perfectly fine for me.
I use BT in the car for handsfree operation and connectivity to my Radar detector
I use wifi, both at home and in the office.
I have notifications on, because I enjoy the ability to receive news updates.
Many APPS I use frequently, need location services on to provide accurate, up to date information.
Here in southeastern New England, 3G service is strong most everyewhere, so I want it active and on.
The iPhone is my ONLY phone, so I do need to have it on to receive or make calls all the time.
I feel that I get the most possible out of my iPhone, without the need to fiddle with it, turning features on and off, every time I want to do something.
For those times when I do use it heavily and need to charge it up, I have a car charger and a usb cable in the office, that I can use when necessary. I have no need or desire to be part of the 1 week battery life contest. I just want to pick the phone up and have it do what I want it to do.
All of that being said, there is also a smaller group of people who are having legitimate problems with their phones. Those who cannot make the phone last more than 3-4 hours, with moderate usage, have some other issues, either with their configuration or hardware, which is causing problems. The numbers of those folks seems to be declining, based on recent posting here, so maybe the latest firmware updates have helped them.
I never had issues thet were so bad and never had to do the restore-as-new procedure that others have. I got my phone the day the 4s was released, set it up and it has worked fine since that day. All I do is keep up with APP and firmware updates religiously.........
