26 Section 2A: Your Phone: The Basics
Removing the Battery
To remove your battery:
1. Remove the protective cover by pressing down on the
back of the cover and sliding it towards the back of the
handset.
2. Grip the battery at the bottom and pull up and out at a
45-degree angle.
Charging the Battery
Your phone’s Li-Ion battery is rechargeable and should be
charged as soon as possible so you can begin using your
phone.
Keeping track of your battery’s charge is important. If your
battery level becomes too low, your phone automatically
turns off and you will lose all the information you were just
working on. For a quick check of your phone’s battery level,
glance at the battery charge indicator located in the upper-
right corner of your phone’s display screen. If the battery
charge is getting too low, the battery icon (
) blinks and
the phone sounds a warning tone.
Always use a Sprint-approved desktop charger, travel charger,
or vehicle power adapter to charge your battery.
Warning: Using the wrong battery charger could cause damage
to your phone and void the warranty.
