and Off" on page 180.)
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.)
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 215.)
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.
Turn off Automatic application sync. (See
"Synchronizing Accounts" on page 74.)

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.)
Check the Battery use screen to review what features
or functions have been consuming your battery
resources. (See "Viewing Battery Use" on page 71.)
Check the Running Services and close any
unnecessary applications. (See "Manage Running
Services" on page 85.)
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 85.)
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 71.)
