iPhone 4S, 64 GB, AT&T Carrier, Black, Incipio Plastic Case.
I'm having the same problem as the rest of you are having and I've just given the Apple Care folks permission to send me a new phone. In addition to the problems you all are having, my 4S ***** itself completely off with no notice. Being a person who relies HEAVILY on my phone for my business and my livelihood, and as you can imagine, going an hour or so with no phone calls worries me. When I pull my phone out to find that it's shut completely off smack-dab in the middle of my highest / peak volume time...........well, it's absolutely unacceptable!
FYI, here are the steps I took prior to getting frustrated to the point of calling my 6 Year "Love Affair" with my iPhone quits..........
1) Tried resolving these battery issues with my local AT&T carrier shop (new sim card, complete reset of system, complete reload from back-up etc.). Long story short ~ No Luck ~ Same Exact Issues!
2) Took it back to the AT&T store for a re-look. Like you all, I was told to shut off my bluetooth, WiFi, Siri Location services, etc., etc.. Although it ****** me off, I went ahead and agreed to allow them to "Gut" my iphone's abilities (the stuff I pay dearly for) in the hopes finding a solution for the betterment of the entire 4S community....................No Luck ~ Same issues!
3) Tried resolving the issue through the Apple Store 25 Miles north of here ~ Same exact procedures as above (steps 1 and 2) ~ No Luck. Same exact problems!
3) Installed the 5.0.1 patch ~ No fixes found............
REALLY????????
