Mophie Juice Pack Helium for iPhone 5 User Manual page 15

The iPhone requires more power to charge past 80%,
so if you want to get the greatest battery boost from
the juice pack, we suggest flipping back to standby
mode until your phone battery is low again. This isn't
the end-all-be-all, but we like it.
What is the best method for charging my juice pack?
Connect the juice pack to a power source using the
micro USB cable that came with your juice pack. The
USB cable can be plugged in to your computer or any
"Made for iPhone" power source with a USB out. You
do not need to remove your iPhone from the juice
pack to charge. Leaving the juice pack on your phone
while charging will actually charge both the case and
your iPhone simultaneously!
How many charge cycles do you get out of the
juice pack? Or, in other words, how long will the
juice pack last?
The juice pack is rechargeable for over 500 full
cycles. A full cycle is when the case is charged from
0% to 100%. Partial cycles, like charging from 25%
to 100%, will not count as a full cycle until all of the
partials equal 100%. After 500 cycles, the battery
in the juice pack may provide less than 75% of the
original capacity. This is normal for any product with
a lithium polymer battery.
