UNU DX PROTECTIVE BATTERY CASE FOR IPHONE 4/4S

Our Amazon's best-selling battery case for iPhone 4/4s, the DX battery case boasts a thickness of just 17mm, while also effectively doubling battery life. This technically advanced case also halves the time needed to re-charge the battery.  It even allows users to sync-and-charge while the case is still attached to the iPhone. Also, made for complete protection, the DX exhibits an ergonomic hand-held fit, an anti-slip coating, and a comprehensive casing to ensure peace-of-mind.

Size is Everything

 Highlighted by its lightweight, ultra slim design, the DX case measures an impressive depth of just 17mm. The sleek protective case is made to fit snuggly and enhance the iPhone 4/4s natural look while still producing astonishing power and functional design.

 Extended Battery Life

 Equipped with a 1700mAh battery cell the DX almost doubles the life of an iPhone 4/4s. The additional power yields six hours of talk-time, 30 hours of music playback, and a hefty 240 hours of standby time.

 "Made For iPhone”

 Awarded the prestigious “Made for iPhone” certification, the DX has gone through extensive testing and quality assurance to ensure reliability. In fact the DX has been proven to give quality power even after 500 full recharging cycles!

 Technically Advanced

 Made with state-of-the-art technology, the DX exhibits a battery which almost doubles the lifetime of the iPhone, allows users to sync and charge with the case equipped, and view current battery levels via the LED battery level indicator.

 Form and Function

Simply, PRESS the button next to the LED display once and the LED’s will light up corresponding to how much power is left in the case. 4 lights =100% - 75%, 3 lights = about 75% - 50%, 2 lights = about 50% - 25%, and 1 light = about 25% - 0%.

 

6. My DX battery case doesn’t charge my phone fully as advertised?

A: Due to high consumption of the battery life, especially for iPhone 4s, 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 the DX Plus Battery Case, for heavy users. Also, please refer to our blog for tips on maintenance and preventive care to ensure you’re getting the most out of your case.

 

7. 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.
