Frequent Questions

Can I use the juice pack battery to charge my phone without stopping what I’m doing?
You bet! After you install your phone in the juice pack case, press the status button on the back of the case for 3 seconds to start charging your phone without having to stop at a wireless charging base or at a wall outlet. If you want to stop charging the phone and save some battery for later, just press the status button again for 3 seconds. When I press the juice pack case status button for 3 seconds the LEDs flash in sequence. What does that mean?•When the LEDs flash in sequence away from the status button 3 times, it means that the juice pack case has begun charging your phone.
•When the LEDs flash in sequence towards the status button 3 times, it means that the juice pack case has stopped charging your phone.How do I wirelessly charge my juice pack case?Simply place the juice pack case on any mophie wireless charging pad or other Qi-compatible charger. Make sure the center of the case is aligned over the center of the charger. Wireless charging will automatically begin when the case is aligned on the charger. If your phone is inside of the case, the juice pack battery and the phone will charge together. What wireless chargers will my juice pack case work with?The mophie juice pack case is compatible with mophie wireless charging pads and will also wirelessly charge from any Qi-compatible wireless charger, including those used on airline flights, in coffee houses, furniture products and consumer vehicles. Will the juice pack battery charge at fast speeds from mophie wireless charging pads and Samsung’s Fast Charge pad?No, the juice pack battery will charge at standard Qi charging speeds, not at fast-charging speeds. How do I charge my juice pack case when there’s no wireless charger available?After using up all the power in the juice pack case, connect it to a power source using the USB-C to USB-A 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 indicator 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-ion 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 block my phone’s fingerprint sensor?No, but we recommend that you reprogram your phone’s fingerprint sensor after you’ve installed the phone in the juice pack case. Does the juice pack case interfere with my phone’s antenna reception?All Wi-Fi and cell phone communications on the Galaxy S9 and Galaxy S9+ are unaffected by the juice pack case. However, the juice pack case may interfere with NFC performance.
Answers
I bought juice pack (Galaxy S9) and wireless charging base (iPhone X, iPhone 8, Samsung). The base is charging the phone while on it's own and charging the juice pack but also on it's own but do not charge when phone is in juice pack. What is wrong?
Hmm. That's strange. We'd be happy to look into this for you. Please reach out to our Technical Support team at 888-866-7443, as they can best advise on what the issue may be.

So will the car vent mount hold my phone securely with this case? I bought the charge force vent mount just for this, I only have a couple days left to return it if it will not hold my phone securely.
The juice pack for the Samsung S9 is compatible with the vent mount.

Is this a ChargeForce case? If not, Why not? I only buy chargeforce chargers anymore for the sheer convenience.
The juice pack is not a charge force case as it is not made with magnets. However, the juice pack for Galaxy S9 is compatible with most Qi-compatible accessories including Charge Stream Pad+, Charge Force Vent mount, and Charge Force Desk mount.

How long does the battery last daily?
The juice pack provides 50% of extra battery to the phone which translates to an extra 11 hours of talk time or 8 hours of video playback. The juice pack can output 5V/1A (5W) to a Samsung S9 fully discharging in about 1.5 hours.

doesn't this thing cause cancer cuz there is a disclaimer that said you may get weirdo kids for preggo ladies .. it's cancerous!
mophie takes matters of product compliance seriously and that in an effort to be compliant with a California law that requires manufacturers to label products that contain even a small trace of any chemical that is on the list.

Can the case be charged wirelessly without the phone in it?
Yes.

I thought that the phone & mophie charged at the SAME time. If the phone charges first and then the mophie afterward, how will I know when the mophie is fully charged? I'm assuming that the phone will read 100% the mophie could still be low?
To check your juice pack battery case’s charging status, momentarily press the status button on your juice pack battery case and the status LEDs will indicate its charge level. Four LEDs means that the case is fully charged, while one LED means that it’s almost empty.

Works great! Worth every penny
I just got an S9 and really wanted a case but my old phone had an awful battery. A case with juice just made sense. I was really expecting a battery with cheesy case but it's an awesome battery with a better case! The phone slips inside (2 part pack) and the case even curves, just a bit, on top and bottom, protecting the glass edges. Tough, rubberized but solid, easy access to fingerprints, power, volume, everything. This just works and so much better than I had hoped.

Love the case
My fiance bought this for me a few weeks ago and I love it. I don't have time to charge my phone anywhere while working a 12 hour day and this case let's me keep going without ever running out of power. It's also held up well with after a few drops here and there cause of my butterfingers.

Great product
Wouldnt be found without my Mophie! I am extremely happy that the design went away from the bezel style that i had for my Galaxy S7!!! Bezel broke way too easily! Do request that Mophie tries adding different colors to their Galaxy S9 Juice Packs!

Good new design
Love it! But they need more colors than just black. It's a shame to hide the pretty new S9 colors.

Needs some improvement
I bought this pack in July upon purchasing my phone and the case has already stopped priority charging in order for me to charge my phone and case I have to pick one or the other. I like the warranty program but I dont like the fact I have to pay to ship the defective product in. I live in Canada and I have to now pay for international shipping which is not okay on top of the 100$ now I have to spend another 20$ to send in a defective unit doesn't seem like it's for the customer type program all in all it's a great product just wish it didnt break so fast considering it's only been like 2 months.

Bulky and heavy, but works like described.
I purchased this Mophie battery case as I'm a bit of a power user, but not always able to charge my phone on the go. Although there are several different charging cases on the market, Mophie's reputation is what made me decide on what's tried, tested and proven.
What I discovered was my phone fit like a glove in the Mophie case. It was solid in there and case provided fantastic protection for my device. Even the top and bottom lip on the front was high enough to protect the face of my phone when the glass was face down. It also connected very quickly to my wireless charger and there wasn't never any issues in that regards.
What I didn't like was that the case is bulky. It feels like two otterbox pursuit cases thick. The fingerprint scanner under the camera on the back of my phone is difficult to reach. It almost an unnatural movement in order to reach it in the deep well. A few times I had to turn the case around as it was difficult to locate the sensor. Finally, the weight. Yes, of course it's going to be heavier as a battery case, but try holding your device with this Mophie case on while watching a movie. This heavy case becomes noticeable heavy in short order. If you think neither the size or the weight situation are not going to be an issue for you. Remember, you got to carry your device with you and this case feels like you have George Costanza's wallet in your pocket.
Overall, I'm pleased with the case for charging and protection. However, given my dislikes, after 3 days, I switched back to my old case. Now I'll be using the Mophie case when I'm out all day knowing that I'll unlikely be able to plug in my phone to charge it.

Not much added power
I'm extremely disappointed with this product. It only adds a few hours of battery life. I will be returning.
