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.

Who has tried using Samsung pay with thier Mophie case? I bought a batterie case on Amazon that is about the same thickness as the mophie and it did work both places i used the NFC Scanning. I want a Mophie for the wireless charging and 2 year warranty

Asked by: Kjr52
The juice pack will not impede LTE or WiFi signals, but due to the need for NFC to be used in very close proximity, your ability to use NFC will vary on the application it is used for, and the strength of both the signal from your phone, and the signal from the other device. As we do not test the case for functionality with NFC, we cannot guarantee that this will work in all instances.

juice pack is rated 3.7 out of 5 by 16.
Rated 5 out of 5 by from Wonderful accessory I purchased this for my husbands new phone. He had an older version for his own phone and loved it. It was so awesome, I bought one for my IPhone and I love it too. Only suggestion for improvement would be to return to the on/off option on the case. This newer version is just on all the time. Which isn't really too much of an issue except you have to keep a closer eye on your battery level.

Rated 5 out of 5 by from I love my Juice Pack It's not to big and I no longer need to worry about my battery running low, even on a busy day when I take 100 photos with my phone. I do miss the switch on my old one.

Rated 5 out of 5 by from Works great! It works great, only flaw is color choice!!! Love the wireless charging!!!:)

Rated 5 out of 5 by from Portable Battery Insurance As unbelievably Smartphone manufacturers eliminated consumers being able to replace a battery (I used to carry several fully charged backup batteries for my previous easy to open Smartphones) the juice pack is an absolute necessity.

Rated 5 out of 5 by from Awesome product This is my third. Galaxy 6, 7 and now 8+. Can't live without them

Rated 4 out of 5 by from Love it! Just bought this case last week and I love it! If u wait til ur phone is at 20% or less it charges it pretty fast. The case does make the phone a lot heavier and the case itself is a bit slippery but other than that I would have given it 5 stars! Love how my phone still fast charges when I connect it even with the juicepack on! Just hope mophie comes out with other colors and stronger magnets on the case.

Rated 4 out of 5 by from Replacement Juice Pack This is my second juice pack for my Samsung S8+. The first one stopped working the first day i received it. It's been 2 weeks since I received the replacement and it seems to Ben working flawlessly. This is my third juice pack and I love the mophie product. Only reason I'm giving this product a 4 is because the first one failed. Otherwise I would have rated a 5

Rated 4 out of 5 by from Good Product Some Issues I recently purchased this case and so far it has been working good. Although it will sometimes not charge the juice pack completely when I plug it in and the phone is completely charged. Same with putting it on the wireless charger. Sometimes the juice pack will not charge at all or completely so I have to unplug/unmount then replug/remount the case to attempt to charge the juice pack.
