Some things to look at:
- Turn off "BOTH" GPS/Maps
- Turn off Wifi.
- If you use Facebook you can adjust settings so it auto updates always, 1hr, 4hr, or never. I chose every 4hrs or if I go to the Facebook tab I can manually update it on the screen.
- My screen goes into sleep mode after 2 minutes of non use.
- I do not use any moving screen savers...Unsure how battery that will drain.
No real battery issues here to complain about.
