Bests & Worsts Reviews from Amazon

I had my S3 for over a year and I had grown accustomed to 2-3 hours of battery life with continuous use, and 4-6 hours of life with minimal use. There are things you just adapt to. After realizing that my battery was distended, and I was due for an upgrade, I did some research, and came upon Anker's S3 Battery replacement. I was skeptical at first, as I tend to dislike use 3rd party products, but the number of positive reviews won me over. The product arrived quickly, 2 business days. The product already came with a 40% charge. After fulling draining the battery, and fully charging it, I average between 12-15 hours a day with steady use. With minimal use I racked up 19 hours (which had me at 10% at the end.) The reason I'm writing this, and writing so highly, is based upon the follow up from Anker's. They actually sent a follow up e-mail to check to see if I was having any problems. Were there issues, all I had to do would have been to respond via e-mail and I'd of gotten support. I gotta say, that's pretty solid customer service. As I've already mentioned, the product works as advertised, and unless my memory deceives me, I feel the battery lasts longer than my original that came with the product.
