Most retailers I searched had bad reviews for this type of battery for this phone. I've never had a bad experience with Best Buy and there were no reviews to count against the purchase and the maker of the battery was different from the other retailers so I gave it a try. I went from recharging the old battery once to twice a day depending on use (use being the one or two five minute phone calls I may get on average) to three days with three bars still to go before recharge HUGE difference with no negative issues. I am going to buy another for a second phone that’s how impressive the difference on the battery life is. I will update this post or you will see another post if this changes.
