Section 2: Understanding Your PCS Phone
2A: Your PCS Phone - The Basics

Always use a Sprint-approved desktop charger, travel charger, or 
vehicle power adapter to charge your battery.

 Only use batteries approved by Sprint. Using the wrong battery 

charger could cause damage to your phone and void the warranty.

1. Install the phone battery in the phone.

2. Plug the prongs of the adapter into an electrical outlet.

3. Plug the round end of the AC adapter into the desktop 

charger and insert the phone into the charger slot.

 

– or –

 

Plug the adapter directly into the charger jack on the phone, 
if the charger stand is not used. (If the phone is on, the 
screen briefly displays a “Charging” notification followed 
immediately by a scrolling battery strength indicator. If the 
phone is off, the screen displays “Phone off. Battery 
charging”.)

4. When the battery is fully charged, unplug the phone from 

the charger. (If the phone is on, the battery strength 
indicator stops scrolling. If the phone is off, the screen 
displays “Phone off. Charge completed”.)

It takes approximately 4 hours to fully recharge a completely 
rundown battery. With the Sprint-approved LiIon battery, you can 
recharge the battery before it becomes completely run down.

 Unplug the charger when not in use. Do not leave the battery 

connected to a charger for longer than a week, since overcharging may 
shorten its lifetime. If left unused a fully charged battery will discharge 
itself over time.
