A few weeks ago I went to the Apple Store because my battery life on my iPhone six sucks! I dealt with it for months only to find out when I got to the Apple Store that I should have done my homework before I even wasted 15 minutes trying to park and another thirty minutes waiting on my appointment. He runs a diagnostic on my phone ( which I had to do before I made the appointment online and had to back up my phone) only to find out my battery is good health. Needless to say he did these four simple steps and my battery has improved tremendously. Follow the steps in the picture to cut off background app refresh. If you notice that your Android or Windows phone are doing the same thing just do a little research. Apps are running in the background that you don’t even use.
