So when I first got the phone when it was released I was getting 24 hrs plus of battery life. Now I'm lucky to get to 18 hrs. I'm not a heavy user of the phone; occasionally browse the Internet, mostly txt, and some pictures. My battery info says my display is at 72%.. Is that normal? The second highest % is the OS at 11%, everything else is <7%. Brightness is on auto.. Any suggestions?
