Frequent Questions

  • 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 2 seconds to start charging your phone. After using up all the power in the juice pack case, just recharge it with the included micro USB cable for more on-the-go power.
    What is the best method for charging my iPhone using the juice pack case?
    Assuming that your iPhone and juice pack case are both fully charged, we recommend waiting until your iPhone has 20% battery left. When the phone’s in the red, press the juice pack case’s status button for 2 seconds and let the case do the heavy lifting. The phone requires more power to charge beyond 80%, so if you want to get the greatest battery boost from the juice pack case, we suggest putting it back in standby mode until your phone battery is low again. This isn’t the end-all-be-all, but we like it.
    What is the best method for charging my juice pack case?
    Connect your juice pack case to a power source using the included micro USB cable. You can plug the cable into your computer or any power source with a USB out, like the USB wall adapter included with your iPhone. 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 actually charge both your phone and the case together!
    Why aren’t the LEDs blinking while my juice pack case is charging?
    After connecting the juice pack case to a power source, 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 disconnect. When all four LEDs are lit, your juice pack case is fully charged.
  • 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 antenna reception?
    Not a chance.
    How many times can I recharge my juice pack case?
    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 of the partials equal 100%.
    For example, if you recharge from 25% to 100% one day (a 75% charge), then a couple of days later you recharge from 50% to 100% (a 50% charge), and a few days after that you recharge from 25% to 100% again (another 75% charge), you will have recharged two full cycles over that period (75% + 50% + 75% = 200%).
    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.

Both are battery based cases, however there are a few differences. The juice pack reserve has a battery capacity of 1,840 mAh, whereas the juice pack air has 1,560mAh. The other difference is wireless charging capabilities. The juice pack air can charge your phone wirelessly, whereas the juice pack reserve can only be charged by wire.

can you plug earbuds into this case

Hi Leah. If you are using Apple headphones, yes. If your headphones have a fat connector, you may need an adapter.

can I plug earbuds into my iphone 6s with the juice pack reserve on?

Yes. The juice pack reserve has a 3.5 port for headphones. While it is compatible with most headphones, it may require an adapter if the headphone connector is too big.

juice pack reserve is rated 4.0 out of 5 by 115.

Rated 5 out of 5 by from Great Case This is a great product! The case is very protective and keeps my phone charged.

Rated 5 out of 5 by from Awesome. I've had another brand for almost a year and it went out two days after the warranty. This one (In Blue, Absolutely cool looking) is smaller and lighter and gives me the same extra phone time as the other brand I had. Get one now while they are on sale. Totally worth every penny at regular price.

Rated 5 out of 5 by from Awesome The Mophie Juicepack Reserve is a phone case that protects as well as charges your phone. I bought myself one for Christmas of 2016 and I’ve used it everyday since. The main pros of this product are its charging capabilities and the protection that it offers. With just seven hours of charging the case, it can bring my iPhone 6s from 10% to 100% four times. The case also protects my phone very well. I’ve accidentally dropped it about 20 times onto tile from 4 feet up and my phone hasn’t suffered a scratch. The only weaknesses of the Juicepack Reserve are reliability and the case heating up. Some nights I plug my phone in and when I wake up, the phone was charged 100% but the case is out of charge. Thankfully, this only happens once every three weeks or so. Another small issue is that when I turn on the case, I can immediately feel it start to warm up. It’s minor though and I do understand that a temperature change can’t be totally avoided. Overall, I would rank this product an A+, it’s reliable, convenient, and well-priced. I would also most definitely recommend this product to a friend.

Rated 5 out of 5 by from Hellz yeah! It's a known fact that the iPhone 6 has a faulty battery, and I needed something to hold a charge while while I traveled to Vegas. The Mophie came at my door the day before my trip, and needles to say, this 'mopho' did what it needed to do. Thank for being clutch!

Rated 5 out of 5 by from Love it I use this all the time and like the fact that I don't have to keep on charging my phone.
