Frequent Questions

  • How do I wirelessly charge my juice pack case?
    Simply place the juice pack case on 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, the juice pack case and phone will charge together.
    What wireless chargers will my juice pack 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, on airline flights, in furniture products with wireless charging, and in consumer vehicles that support wireless charging.
    Is the juice pack case’s wireless charging compatible with Samsung’s Fast Charge Wireless Charging Pad?
    Although the juice pack case will wirelessly charge from a Samsung Fast Charge Wireless Charging Pad, it will charge at standard wireless charging speeds, not at 1.4x Fast Charging speeds.
    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?
    If 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 cable included with your phone. You can plug the cable into the wall adapter included with your phone or any power source with a USB out. 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.
  • Will Samsung Adaptive Fast Charging work on my phone when I’m charging the phone and juice pack case together from the Samsung Adaptive Fast Charging wall charger?
    Yep. Your phone will Fast Charge from the Samsung Adaptive Fast Charging wall charger while it’s inside the juice pack case.
    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 check the status indicator 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 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 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?
    All Wi-Fi and LTE functions on the Galaxy S8 and Galaxy S8 Plus are unaffected by the juice pack case. However, the juice pack case may interfere with NFC performance.

Why is the juice pack so slick? It will definitely fall out of anyone's hand. Why didn't you add ANY grip to the juice pack? Where is an app to monitor the juice pack FROM the S8+ while it is running?

Asked by: sanjsrik
Thanks for reaching out! The juice pack for the Galaxy S8+ is made with our standard black matte material. There is no app to monitor the amount of charge on your juice pack. To check the status of your juice pack simply push the status button located on the back of your juice pack. The status LEDs will indicate its charge level. Four LEDs means that the juice pack is fully charged, while one LED means the juice pack is almost dead. If you would like a visual of what is being described please visit http://www.mophie.com/shop/galaxy-s8/juice-pack-galaxy-s8-plus?a92=12 and download our user manual located under Tech specs.

Can you apply and use a magnetic vent clip or dash clip with the mophie case without ruining it?

Asked by: Corrie
We do not recommend using the juice pack for the Galaxy S8+ with 3rd-party magnetic mounting systems. The magnets in the case will firmly attach it to mophie charge force mounts, but we cannot guarantee that they will adequately hold when used with a 3rd-party magnetic system. Check out our charge force mounts here, http://www.mophie.com/shop/docks

Reviews

juice pack is rated 3.9 out of 5 by 45.
Rated 5 out of 5 by from Good design Case is the perfect size, size of battery is sacrificed for comfort. Overall, I rather have this case over the other bigger and bulkier. It's not for everyone, but you have to chose comfort, this case such gives me an extra 60% charge. Or I can go back to that other case, which charges my phone 2 1/2 easily, but is really bulky. I love both cases, but for now, I'll stick with mophie, not only because of size, but the wireless charging feature is what won me over.

Rated 5 out of 5 by from Great user experience I purchased this as my primary case, I've grown to appreciate the elegant design and ease of use.

Rated 5 out of 5 by from Great Design I bought this because I felt naked without a mophie on my new S8+ edge. I used one on my S6 edge and loved it and it's the same with the S8+

Rated 5 out of 5 by from Nice upgrade from the S6 version. I have owned for a month of so now and I am in awe of the new features. And to boot you get a 2 Year warranty. Nice!

Rated 5 out of 5 by from Love Wireless Magnetic charging I have been looking for this technology as I have tried wireless charging which only works if you have your phone in the exact right spot and have used magnetic mounts in my car without having to use clamps. This device and the desk and car mounts serve both of those purposes in one shot. The only thing that would make it better is if they developed a cigarette lighter car mount that is directly powered by the mount and did not require and additional cable to plug into the base, this mount would also have 2 auxilary USB ports to charge other devices with if needed. Overall this product is great and exactly what I have been looking for.

Rated 5 out of 5 by from Great Design and form I bought a few weeks back from the website and very happy with it. Have not had occasion to use extra battery but will be doing so on trip to Yellowstone soon.
