Frequently Asked Questions
How does it work?
The mophie juice pack® has a rechargeable lithium battery inside. When you slide your phone into the case, a connector at the base plugs into the micro USB port at the bottom of your S III. Flip the standby switch on the back from red to green to start charging your phone. After using up all the power in the juice pack, just recharge it with the included micro USB cable for more on-the-go power. It’s as easy as that.
How do I charge the mophie juice pack®?
Simply connect the juice pack to a USB power source, like a wall charger, car charger, or your computer, with the included micro USB cable. You can charge the juice pack while it’s on or off your phone. If you charge with the case on, it will also charge your S III!
Can I sync my S III while the juice pack is on on phone?
Yes! You can charge and sync your S III without removing the juice pack via the included micro USB cable. Pretty cool, huh?
Does the juice pack interfere with antenna reception, S Beam, or NFC (Near Field Communication)?
Not a chance. Our case will not effect your signal strength or interfere with your phone’s NFC or S Beam capability. You can still share photos, websites, contacts, etc. with the juice pack on your phone.
What colors are available?
This juice pack is available with a soft-touch black matte finish or a beautiful, high gloss white with metallic silver accents.
How do I get the most battery power out of the juice pack?
Correctly using the standby switch will give you the best battery boost. The S III uses power to be on a constant charge, so only charging when you need power is the best way to use the case. We recommend waiting to charge until your phone is down to 20% or less. Limited use of your phone while charging will also increase the percentage of battery the juice pack will give you.
How many charge cycles do you get out of the juice pack? Or, in other words, how long will the case 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 will be less than 75% of the original capacity. This is normal for any product with a lithium battery.
Will I always receive double the battery life with the juice pack
It is not guaranteed that you will receive double the battery life. The amount of additional battery you will receive from the case depends on a variety of factors that are different for every user.
Will the juice pack charge any other Android™ phones?
No. This juice pack is only compatible with the Samsung Galaxy S® III. You can, however, use one of our powerstations to charge virtually any other smart phone!
