Low Battery Indicator When the battery level is low and only a few minutes of talk time remain (~15% charge), a warning tone sounds and the "Battery low" message repeats at regular intervals on the display. In this condition, your device conserves its remaining battery power, by dimming the backlight. When the battery level becomes too low, the device automatically turns off. The on-screen battery charge is represented (by default) as a colored battery icon. You can also choose to display a percentage value. Having a percentage value on-screen can provide a better idea of the remaining charge on the battery. Ⅲ Press ➔ and then tap Settings ➔ Display ➔ Display battery percentage. For more information, refer to "Display Settings" on page 276. 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: • Reduce your backlight on time. • Turn Bluetooth off when not in use. • Turn Wi-Fi off when not in use. • 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 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. • Use the Power Savings Widget to deactivate hardware functions such as Wi-Fi, Bluetooth, GPS, Synchronization, or LCD brightness setting. • Check the Battery use screen to review what features or functions have been consuming your battery resources.
