Frequent Questions

  • What is mophie “Iso-Flex” technology?
    The mophie juice pack FLEX battery case features an Iso-Flex frame. Iso-Flex is an advanced polymer material designed to provide superior protection against drops and hard falls by absorbing and dispersing energy on impact rather than compressing and rebounding like a typical elastic or rubber material. The Iso-Flex frame also features raised corners that offer additional protection against scratched and cracked screens.
    What does “MIL-STD-810” mean?
    The juice pack FLEX case has been designed and built to comply with U.S. military standards for resistance to drops and hard falls.
    How do I wirelessly charge my juice pack FLEX case?
    Simply place the juice pack case on the mophie wireless charging base or any Qi-compatible charger. (mophie charge force products will automatically align the juice pack case for a proper charge.) Wireless charging will automatically begin when the case is aligned on the charger. If your phone is inside of the case it has priority and will charge first, then the juice pack case will charge.
    What wireless chargers will my juice pack FLEX case work with?
    The mophie juice pack case is compatible with all mophie charge force products. It will also wirelessly charge from any Qi-compatible wireless charger, and is compatible with other wireless charging technologies, such as those used at coffee houses, restaurants, in furniture with wireless charging, and in consumer vehicles that support wireless charging.
    How does the extra battery work?
    When you slide your phone into the juice pack case, a connector at the base of the case plugs into the port at the bottom of the phone. Press the status button on the back of the case for 3 seconds to start charging your phone. After using up all the power in the juice pack case, just recharge it for more on-the-go power. If you want to stop charging the phone, press the status button again for 3 seconds.
    What is the best method for charging my phone using the juice pack case?
    Assuming that your phone and juice pack case are both fully charged, we recommend waiting until your phone has 20% battery left. When the phone’s in the red, press the juice pack case’s status button for 3 seconds and let the case to do the heavy lifting. The phone requires more power to charge past 80%, so if you want to get the greatest battery boost from the juice pack case, we suggest putting it back into standby mode until your phone battery is low again. This isn’t the end-all-be-all, but we like it.
  • How do I charge my juice pack case when I’m on the go?
    After using up all the power in the juice pack case, connect it to a power source using the included micro USB cable. You can plug the cable into your computer or any power source with a USB out, like the USB wall adapter included with your phone. You do not need to remove your phone from the juice pack case to charge. In fact, leaving your phone in the juice pack case while charging will charge both your phone and the case together.
    Why aren’t the LEDs blinking while my juice pack case is charging?
    After you begin charging the juice pack case, the LED status indicators will start blinking to indicate charging. The lights will turn off after 30 seconds allowing for a good night’s rest. Remember to press the status button to check the battery’s charge status before you take your juice pack case. When all four LEDs are lit, your juice pack case is fully charged.
    How many charge cycles can I get out of my juice pack case? Or, in other words, how long will the juice pack case last?
    You can recharge your juice pack case for over 500 full cycles. A full cycle is when you recharge the case 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 full cycles, the battery in the juice pack case may provide less than 75% of its original capacity. This is normal for any product with a lithium polymer battery.
    Does the juice pack FLEX case block the speaker, microphone, camera, or any other ports?
    Of course not. In fact, the juice pack case 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 case interfere with my phone’s antenna reception?
    Not a chance.

Reviews

juice pack FLEX is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Serious protection As a mom of toddlers, my phone gets dropped (at times, chucked) regularly. My husband uses a mophie battery case, but I was always nervous to give-up my protection for additional power. This case is literally the best of both worlds! In the short time I've had my FLEX case, it's protected my phone (and screen) from multiple drops, and provides a consistent charge. And, it charges wirelessly! Very pleased with this product.
