Location services use up not only battery but also mobile data, so
turning it off would be a good idea for saving both of these precious
resources. Location services is found in the settings and if you aren’t
willing to part with this feature, you can select the Power saving
location service mode that will only use this feature when using Wi-Fi
and mobile networks, instead of the default high accuracy mode which
uses GPS, Wi-Fi and mobile networks.
The Samsung Galaxy Note 4 has a great quick setting menu that you get
to by swiping down from the top of the screen with two fingers. There
you’ll find a bunch of toggles that you can easily switch on or off with
a tap. They aren’t in alphabetical order so you’ll have to look around
for the various services: turn off Bluetooth, NFC, and GPS if you don’t
need them.
