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.

juice pack is rated 4.0 out of 5 by 21.
Rated 5 out of 5 by from Very heavy S8 Bought this a few months ago, it extends the battery life so much I havent come close to running out. But it is very heavy.

Rated 5 out of 5 by from dont leave home without it I am so excited to have this product!! I have used the juice pack several times already! I do not always have access to charge my phone nightly and this has saved me several times already! We have all had the issue when we have our google maps pulled up and get the warning of low battery. I can make it to my destination, but how will I find my way home? Simply push the button and now I have plenty of battery.

Rated 5 out of 5 by from great customer service I have been using mophie vases for years and ran into my first problem with the S8 case I bought. I let mophie know and they immediately sent me a replacement Great product Great customer service This company ROCKS

Rated 5 out of 5 by from Great Protection Thus is my second mophie juce pack. My first experience was with the Samsung 6 Edge. I liked that case tremendously. Now I have a comparison. The mophie cases are identical in all but one feature. The S 6 case had an actual switch to push over from red to green to indicate when you are using the juice pack to charge the phone. The new case uses the same one push button that verifies the amount of charge that is remaining in the pack. Not sure how I feel about that yet. I haven't had any issues of accidentally turning on the pack so far. I anticipate that this will be quite good at protecting my phone. I've accidentally dropped it a couple of times on to cement and a hard industrial tile floor. So far everything is great. I don't have a screen protector. I am curious to hear if anyone has the mophie case with a glass protective screen. As i said, I had the S 6 with no screen protectors. No problem for 2 years with several drops.

Rated 5 out of 5 by from Couldn't wait to get it! I previously had the mophie for my samsung s6 curve and loved the design, function and ease of use! When I bought the new S8 I was waiting patiently for The Mophie to be offered for the new phone. It came and I am thrilled! Not only is the case exactly as I expected but I also purchased the beautifully designed magnetic charging station. Looks great and quickly charges the case and phone without ugly wires! Get it!

Rated 5 out of 5 by from Best one I've owned I have a Mophie for my Galaxy S5 and iPhone 5S and use them both every day. When I decided to upgrade to Galaxy S8, I waited for mophie to release this model. At first I missed the switch but no longer. This design is sealer and easier to use. I won't have a smartphone without a mophie.
