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.

When the cell ohjone battery is at 100 percent and the case is supposed to be charging, is my connect to charger continuously charging both? I don't want to overcharge my cell phone battery.
With priority+ fast charging, your Galaxy S8+ recharges first, and then the juice pack battery recharges itself. It will not charge both at the same time.

Is thus case shockproof ? And has it been drop tested ?
The juice pack has high-impact protection built into the case’s design. This includes raised corners that provide edge-to-edge screen protection, and internal bumpers that add extra cushion to the edges. This protects against drops and hard falls.

Juice pack does the job
Works as expected, adds a good amount of thickness but that's okay for the extra battery.

Best overall juice pack brand
They say you get what you pay for, if that's the case then this product should cost at least double what is already is. The price is perfect for what your getting this is the only brand I will be buying phone cases from now.

Mophie design is one up on ther rest.
I ordered another Battery Case for my Samsung Galaxy S8+ from another manufacturer. I Then recieived my Mophie. I returned the other non Mophie. This Mophie most importantly is wireless charging with pass thru to the phone. It also magnetically attaches to the Mophie charging pads and stands for secure connections. If you have other Qi pads, they are compatable as well. I've been a Mophie customer since my Apple Iphone days. To me, it's worth a little extra to have the design and reliability of Mophie.

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.

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.

Sweet Product!
I bought the juice pack with my phone and have been extremely satisfied with it since day one. Overall, I like the fact that it adds to the heft & bulk of the phone; it gives me more to hold onto and makes me feel more secure & less likely to drop the phone. It could be a bit smaller and more colors would be great, but that's just sauce for the goose... I'm having a hard time breaking myself from feeling like I always need a charger at hand as this battery provides a lot more up time than I can use in a day.

Handsome battery case that doubles battery life
Today's smartphones are very thin, but at the expense of providing limited battery life. For me, I am willing to forego thinness for extended battery life. Mophie Juice Pack provides me with that solution - doubling the battery life of the phone while resulting in overall phone thickness that is still decent. The rubberized finish provides excellent grip. The builtin wireless charging functionality is a nice feature.

I've bought several kinds of power phone packs but by far the Mophie ceases to amaze me. The magnetic back of the device is an awesome feature and will co tinue to buy more device in the future.

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.

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.
