Extending the life of my Samsung Galaxy S3

Extending the life of my Samsung Galaxy S3 (Anker 2200mAh).My smartphone battery was dying. I was wondering what I could do, extending the life of my Samsung Galaxy S3. In the beginning, I would have only used up 30% of my battery.

As I started to use more and more Apps (and the camera), I noticed that the battery in my Samsung Galaxy S3 would eventually have about 50% at the end of the day (after two years of use). I was fine with that. I had no real reason to upgrade my smartphone.
