Here's a tip to save some battery life... Any features / toggles that you are not currently using (GPS, Bluetooth, Wifi, NFC), turn off. To make it quick and easy to toggle them all off and on, I use an app called Power Toggles. I created a widget on my homescreen that has the following toggles:
Wifi
GPS
Bluetooth
Screen Lock
Flashlight
Sound Toggle (Mute/Vibrate/Sound)
Battery
This way when I don't use any of those features, I can easily disable every single one with a few quick clicks.
Hope this helps anyone looking to simplify their toggles 
*** Edited to add labels ***
