Charging Your Device’s Battery
To charge the battery, do the following:
1
Attach the power adapter to your device.
Locate the power adapter that came with your device. Insert the charger lead (the small round end of the
adapter) into your device’s charging outlet (the small round hold located at the top of your device) and plug
the adapter cord into a standard 120V AC electrical wall outlet.
2
Let the device charge for at least four (4) hours.
Rest the device in a safe place and let the batteries charge for at least four hours, or overnight. As the device
is charging, you will see a charge indicator (
) blinking over the battery icon the upper-right corner of
the device display. When fully charged, the charge indicator will stop blinking. You’re ready to go!
Battery Charging Time
Initial charging time for your device’s lithium ion battery is approximately four hours. Recharging time is the
same, depending on how discharged the battery has become.
Use and Standby Times
With a fully-charged battery, you can use your device for one day. In power-saving (or sleep) mode, the battery
should last seven days. These times are approximate however; battery operation times vary according to how
you use your device, signal conditions, and other network settings made by T-Mobile.
Conserving Power
Your device has a power-saving feature that automatically reduces power to the device after 10 minutes of
inactivity. This is also referred to as “sleep mode”. In sleep mode your device will still receive messages and calls.
To wake the device, simply press any two control keys simultaneously or open the display lid.
If you have set a device security code, as described in
on page 31, you will be
prompted to enter your three-digit security code before the device will “wake up”. This power-saving feature
conserves battery power, as well as provides security when used in conjunction with the device security feature.
