Installation
• Remove the top cover and slide the GALAXY S8 into the
battery case.
• Install the top cover in the correct orientation and snap
into place on all sides.
• Removing: Pull off the top cover, slide the GALAXY S8
out, then reinstall the top cover.
Note: When the battery case is turned on, you will
notice the charging signal appear on your S8+
screen’s battery indicator. When charging is
finished, the signal will disappear. The battery
case includes a USB charging cable. Only use the
provided USB cable to charge and sync your
battery case with a wall charger, or with a
laptop/desktop. Avoid using aftermarket and
non-standard cables as they can cause damage
to the battery case, your phone, and/or cause
overheating or fire.
Charging your Battery Case & phone
together
• Connect your batttery case (S8+ already installed) to the
USB power cable.
• Connect the USB power cable to any USB power source
such as a computer to start charging. The battery case is
programmed to let your GALAXY S8 charge first, then the
battery case will charge.
• Charge until the LED indicators indicate fully charged (all
4 LEDs are solid).
Charging your S8+ using the Battery
Case
• Press and hold the power button for about 3 seconds to
turn on the battery case and start charging your S8+.
• Press and hold the power button for 3 seconds again to
deactivate the battery case and stop charging. This can
significantly save more battery power to charge the S8+
next time.
