ⅷ Turn Wi-Fi off when not in use. (See “Turning Wi-Fi
On and Off” on page 177.)
ⅷ Turn 4G off when not in use. (See “Turning 4G On
and Off” on page 180.)
ⅷ Turn off Sprint Hotspot (Wi-Fi hotspot) services when
not in use. This is one of the largest drains on your
battery as it is not only transmitting a Wi-Fi
connection to your devices but is also doing it while
using a 4G connection. (See “Sprint Mobile Hotspot”
on page 181.)
ⅷ Deactivate the GPS when not needed. Most
applications using this function will periodically query
the GPS satellites for your current location; each
query drains your battery. (See “Activating Location
Mode” on page 211.)
ⅷ Do not wait until your battery is completely depleted
before charging your device. Repeating this process
of a complete discharge and recharge can over time
reduce the storage capacity of any battery.
ⅷ Turn off Automatic application sync. (See
“Synchronizing Accounts” on page 73.)
ⅷ Use the Power Control Widget to deactivate hardware
functions such as Wi-Fi, Bluetooth, GPS,
Synchronization, or LCD brightness setting. (See
“Adding and Removing Widgets” on page 35.)
ⅷ Check the Battery use screen to review what features
or functions have been consuming your battery
resources. (See “Viewing Battery Use” on page 70.)
ⅷ Check the Running Services and close any
unnecessary applications. (See “Manage Running
Services” on page 84.)
ⅷ Use the Task Manager feature to end/shutdown
background applications that are still running. These
minimized applications can, over time, cause your
device to “slow down”. (See “Using the Task
Manager” on page 84.)
ⅷ Animated wallpapers use processing power,
memory, and more power. Change your Live
Wallpaper to a non-animated Wallpaper gallery or
Gallery image. (See “Changing the Display Screen”
on page 70.)
