Device Basics ᮣ Plug the flat end of the charger into the device's charger jack and the other end into an electrical outlet. The device turns on with the screen locked and indicates both its charge state and percent of charge. With the Sprint-approved Li-Ion battery, you can recharge the battery before it becomes completely run down. Extending Your Battery Life 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: ⅷ Reduce your backlight on time. (See "Changing the Backlight Time Length" on page 64.) ⅷ Turn Bluetooth off when not in use. (See "Turning Bluetooth On and Off" on page 127.) ⅷ Turn Wi-Fi off when not in use. (See "Turning Wi-Fi On and Off" on page 154.) ⅷ Turn 4G off when not in use. (See "Turning 4G On and Off" on page 157.) 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 158.) 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 192.) 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 67.) 2A. Device Basics 23
