Mophie Juice pack air User Manual page 7

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.
What are the benefits of switching the juice pack to
standby mode?
Using the standby switch will give you the biggest battery
boost from the juice pack. The iPhone uses additional
power to be on a constant charge, so charging when your
phone battery is low will let you get the most from your
juice pack.
Can I sync my iPhone while the juice pack is still attached?
Yep. You can sync wirelessly if your iPhone and laptop are
connected to the same Wi-Fi network. Just flip your
powered juice pack to charging mode or connect to any
USB power source. Pretty cool, huh?
What is mophie's return policy?

upon return. Visit mophie.com for a full "Return Policy. "
Will I always receive 100% extra the battery life with my
juice pack?
We cannot guarantee that you will receive a 100% battery
boost. The amount of additional battery you will receive
depends on a variety of factors that are different for every user.
Does the juice pack block the speaker, microphone,
camera, or any other ports?
Of course not. In fact, the juice pack is designed to act as a
virtual speaker box! Sound is redirected from the bottom of
the phone to the front resulting in a richer, fuller sound quality.
Does the juice pack interfere with antenna reception?
Not a chance.
