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.

juice pack reserve is rated 3.9 out of 5 by 131.
Rated 5 out of 5 by from Works as advertised I've been buying mophie products for years Let's see how long It lasts before it breaks or becomes inoperable

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 Great product This is my second mophie. The first was the air, which is SSOOOO slippery it kept falling out of my hand and got really beaten up. This one is so much sleeker and not as slippery. I love it. I wish it had 100% or more recharge, but I'm happy with it. I wish I had gotten my daughter this one instead of the air as it's slipped out of her hand and shattered her phone 3 times!!!!

Rated 5 out of 5 by from Very reliable case The case is wonderful it feels nice it not too big it's not heavy. My only complaint with this case only is it needs to hold more battery. If you are planning on keeping your phone for more than a year than you should get one of the cases with more battery. But overall I love it

Rated 5 out of 5 by from Mophie on the Road I am a long distance bicycler that uses an iPhone 6S as my cycling computer. When riding longer distances using multiple apps which utilize GPS the phone can be drained of its power long before the ride is completed. This past weekend I road in a 100+ mile event. When the phone's power indicator read 40% I switched on my mophie and the power was restored to 100% while using the apps which had drain the supply in the first place.
