Frequently Asked Questions
Does the mophie juice pack plus® charge the iPhone 4S?
This mophie juice pack plus® does work with the iPhone 4S.
What are the benefits of switching the juice pack plus to stand-by mode?
Using the stand-by switch will give you even more total battery life, as the iPhone uses additional
power to be on a constant charge.
What are the best methods for charging your juice pack plus?
Connect the mophie juice pack to a power source using the USB cable that came
with your juice pack. The USB cable can be plugged in to your computer or any
“works with iPhone” wall-plug style power source with USB out. You can either charge
the juice pack plus with the iPhone inserted or charge them separately.
Can I sync my iPhone while the juice pack plus is still connected?
You can charge and sync your iPhone to iTunes without removing it from its
juice pack® via the included usb cable. Pretty cool huh?
How many charge cycles do you get in the juice pack plus for iPhone?
The juice pack is rechargeable for over 500 cycles. (Full cycles, partial cycles don’t count as full.
So, you can charge your juice pack 10% of the way 10 times before it counts as a complete cycle.)
Don’t be afraid to top it off! After 500 cycles, its fully charged capacity will be less than 75%
of the the capacity when it’s new.
Does the juice pack plus block the speaker, microphone or cameras?
Of course not! In fact, the case is designed to act as a virtual speaker box, redirecting sound from
the bottom of the iPhone 4 to the front, resulting in a richer, fuller speaker sound quality.
Does the juice pack plus interfere with antenna reception?
Not a chance.
Will I always receive double the battery life with my juice pack plus?
We cannot guarantee that you will receive double the battery life. The amount of additional battery
you will receive depends on a variety of factors that are different for every user.
