• Using BatteryBoost to charge your smartphone
There are several methods you can use to extend the battery life:
• Adjust Wi-Fi settings:
· Shorten the Wi-Fi range — If the devices you are connecting to your Wi-Fi
network are always near the mobile hotspot device, shorten the Wi-Fi range.
· Set the Wi-Fi Standby timer to a shorter period — Reduce the amount of time to
wait when no devices are connected to either Wi-Fi network before going into
standby mode (Wi-Fi radio turns off).
• Adjust display settings:
· Dim the screen — Reduce the LCD’s brightness level.
· Set the Display Timeout to a shorter period — Reduce the amount of time to wait
without the LCD being used before turning the screen blank.
