Frequent Questions

  • Will this case work with the leather back LG G4 phone?
    This juice pack is NOT compatible with the leather back version. The juice pack for LG G4 is only compatible with the plastic back versions.
    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 G4. When your phone gets low on battery power, just flip the standby switch on the back of the juice pack 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 LG!
  • 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%. It's only after 500 cycles that 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 compatible only with the LG G4. You can, however, use one of our portable powerstation batteries to charge virtually any other smartphone!
