Solved my Galaxy S3 battery charging problem
Very happy with it. Solved my problem. I had purchased two batteries for my Galaxy S3 in the last year, as others suggested to me that the battery was bad due to the quick battery drain.  Now I am convinced my problem was related to the two OEM chargers I had. One of the chargers seemed to have a poorer connection in the phone port, but with both of the chargers my battery would show fully charged and then, after unplugging the charger, the battery indicator would drop down to 30%.  Now, I simply charge one battery with this wall charger while I have the other one in my phone.  The battery now lasts me for about two days. The only inconvenience is having to open the phone to put in the battery, but I'm okay with that, because it is less expensive than buying a new smartphone.
