1. What makes the DX-Free so great?
A: The newest addition to the exceptionally popular DX Series line, the DX-Free is the result of four generations of iPhone engineering and design combined into a single case. We have taken all the best parts of the DX-3, DX-4, and DX-5 (all top sellers on Amazon) and have created a perfect blend of power, protection, and appealing design. With an extra-large battery cell while still keeping a small frame, the DX-Free is the new standard in iPhone 6/6s battery case design.
2. Does this case work for the iPhone 5/5S? What about the 4/4s?
A: The new DX-Free does not work for the iPhone 5/5s or the iPhone 4. It only works for the iPhone 6/6s. If you are interested in iPhone 4 and iPhone 5/5s products please see "Battery Cases".
3. Can I replace the bumper of the case if it is lost or broken?
A: Yes, additional parts can be purchased on our website in the add-on section.
4. How much battery life can this case provide?
A: The DX-Free has a battery capacity of 2,400mAh which approximately yields another 100% power to the iPhone 6.
5. How do I turn the case ON and OFF?
A: The DX-Free uses an ON/OFF button which is located on the back of the case below the LED battery life indicator display. Simply PRESS and HOLD the button for 2 seconds to turn the case ON or OFF.
6. What is the LED light on the back of the case used for?
A: The LED light on the back of the case serves a couple purposes. First, when charging the LED will flash red to notify you that it is being charged. Once the charge reaches 100% the LED will flash blue. The LED also can display how much battery life is left inside the case.
7. My DX battery case doesn’t charge my phone fully as advertised?
A: Due to high consumption of battery life of specific users, our cases might only be able to charge up to 90% of the battery. The age of the battery is also another factor which might cause the battery case not to be able to charge the phone fully to 100%, this is a common occurrence among heavy usage consumers. We recommend reading our blog for tips on maintenance and preventive care to ensure you’re getting the most out of your case.
8. What is the best way to get the most out of my battery case?
A: Some helpful tips include: Fully charging the case by itself overnight before using the product for the first time, turning on the case only after the internal battery of the iPhone gets low and keeping the battery case out of extreme temperatures to minimize battery degradation.

9. Does the DX-Free support sync charging and syncing through the case itself?
A: Like all uNu products, the DX-Free does allow charging and syncing through the case. Users will be able to use the included micro-USB cable to connect the DX-Free to a computer so that they may charge and sync the iPhone 6/6s.
10. Does the DX affect the iPhone’s camera, phone signal or speakers?
A: The DX-Free is designed to work with all the original features of the iPhone 6/6s.
11. My case got stuck because I use an invisible body armor on the back of my phone, what can I do?
1. The DX case has a relatively large headphone jack opening, so it should fit a slim sized stick or pen. 2. Find a pen that can fit inside the opening, wrap it with tissue paper (preventing scratches when removing the phone from case). 3. Dip the slim pen inside the headphone jack opening, and push the phone outwards from the casing. 4. Now you should be able to remove the unit easily.
We hope this trick helps with your issue.
Please also note that DX-Free is designed and engineered to fit iPhone 6/6s precisely, plus it features a premium rubberized coating. Therefore, some post applied back protective film (especially the thick scratch-proof ones) will make the fit to the DX case extremely tight, thus creating making it difficult to remove.
