I thank those of you who have made serious replies. Because I really had no experiences with which to compare what I was experiencing with the G3, I never thought the device might be defective. I had both called AT&T tech support, and had the phone looked at in store, no one suggested I might have a defective device.
I am glad to see some adults on here.
I too am glad to see adults on this forums because they leave the child like conclusions out of their reviews of products.
I have owned iPhones from the 3G through the 4, which my wife has now. I started using Android a few years ago with the Samsung Captivate (a Galaxy S device).
The Captivate needed some polish, as it was running Froyo when I bought it, but it also had some potential. I eventually sold it to buy a HTC Inspire 4G. It too, had potential, but I am a tech lover, so I sold it when the Galaxy S II came out.
The SII had Gingerbread and was an all around better phone than the Captivate and Inspire in my eyes. I enjoyed the lightweight construction (Apple fanboys call it sub-standard construction, or cheap) as it felt light in my hand and pocket. Samsung was also fine tuning TouchWiz, which I personally like.
After the SII, I bought a Galaxy Note. It is a significantly sturdier device than the SII in a sense that it weighs more and is bigger due to the larger screen. A great device, which in my eyes is already ahead of the iPhone in numerous ways like input, camera and screen size. I also gave this to my wife as she is using it instead of her iPhone for the stylus input alone. She hasn't complained about it once since I gave it to her. Oh, it is upgraded to ICS with no problems whatsoever.
I now own a Galaxy S3 16GB Marble White with a 32GB SD card installed. I run 84 or so apps on it and use it every day. In the month or so I have had it, I use it on WiFi and off. My WiFi has disconnected at home four times to my knowledge and every time it happens, it is because my Apple router was power cycling itself. Hmmmm.
Within that month, my battery life has been on par every day with every other phone I have owned in the past few years, including my iPhones. I take it off the charger at 7 AM, and have around 20 to 30% battery when I put them on the chargers at night around midnight. If I stream video on 4G, because I am not in a LTE area yet, the battery does seem to drain a little faster, but that is why I carry a spare charger in my battery in my laptop bag, so I can live it up and not worry about the battery. On top of that, I went almost a full month and only used around 1.25 of 2.0GB data on my plan.
All in all, I would have to rate the Galaxy S3 better that the iPhone, but that is my opinion, not just because I like Samsung or Android and hate Apple with a passion. The SIII brings to the table a stylish device with a 4.7" screen that honestly is gorgeous. I have never had my device drop WiFi without a hardware failure from my router, I don't bleed data, and surely don't run my battery down every day. If you had the device, it was most likely defective in some way, as others have said.
If you took the device in for replacement/service and was told by techs that there was nothing wrong with it, then that only leaves one explanation for the problems. User Error.
