Ok so it's obvious after reading all the threads and even starting one asking who is NOT having problems with their battery that it's a hit or miss problem. However one thing I do know is something that I did and many others have done that has helped their battery life tremendously. Use your phone until it dies completely, to the point where it turns itself off. Then plug it into the wall adapter charger and KEEP IT OFF while you charge it until full. I would suggest even letting it charge a little longer after it reaches 100%. I let mine charge for about 3 hours while OFF after the complete drain. Ever since my battery has improved significantly and I've seen others mention the same thing helped them. Give it a shot, you've got nothing to lose!
