Power Saving Settings
Control your phone’s data delivery and battery usage through this settings menu.
Active applications, light levels, Bluetooth usage, and GPS functionality all act to drain your
battery. The following is a list of helpful tips that can help conserve your battery power:
● Reduce your backlight on time.
● Turn Bluetooth off when not in use.
● Turn Wi-Fi off when not in use.
● Turn 4G off when not in use
● 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
phone but is also doing it while using a 4G connection.
● 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.
● Do not wait until your battery is completely depleted before charging your phone.
Repeating this process of a complete discharge and recharge can over time reduce the
storage capacity of any battery.
