The Most Reliable Power Continues

uNu’s DX Protective iPhone 5 / 5S Battery Case is the successor of its No.1 best-selling iPhone 4 / 4s battery cases on Amazon.com. Designed to be more than just a battery case, uNu’s new DX case features unbridled power wrapped within a refined frame, which brings power and protection to a new level.

Our Batteries Last Longer…Way Longer.

Our (2300mAh) battery brings you power like never before. With the ability to charge the iPhone 5 an additional 100%, the DX-5 gives you an additional 10 hours of talk time or 8 hours of additional web-browsing. The DX-5 has got your power concerns covered.

360° of Protection

We drop tested the phone thousands of times, to ensure that every conceivable effort has been made to make the DX-5 a complete 360° of protective armor. With an additional lip that surrounds the screen, extra-strength corner protection, and a provided screen protector, the DX-5 is ready for almost anything

Smaller, Lighter, Better

Equipped with the newest battery technology, the DX-5 is only 15.5mm thick and weighs less than 3 ounces! Meaning that bringing your case wherever you go has never been easier.

Designed with Style in Mind

Combining geometrical shapes and the anatomy of the human body, our designers created the perfect blend of beauty and function. With an ergonomic hand-feel, subtle color tones, and easy-to-use functionality, the DX-5 has the style to impress just about anyone.

Made for iPhone

Tested and approved by Apple labs, the DX-5 has undergone numerous stress tests to ensure quality, ability and safety. Awarded the coveted “Made for iPhone” certification, the DX-5 is officially an iPhone’s best friend.

Color: Matte Black
[[VIDEOID:mo2A2FC7EBIPOCR]]This phone case is wonderful. It fits my iPhone 5S perfectly and it does a good job of protecting it and keeping it charged. It comes with the case, a manual, a 34 inch charging cable, an extender plug for your ear buds and a protective screen film cover. I did notice that the screen protector seemed to have some glittery material in it and as a result I did not install it on my phone. The product and the built in Lightning cable is MFI certified by Apple to be compatible with your Lightning connector iPhone. The case includes a 2300 mAh lithium battery that can basically recharge your iPhone 5 or 5S and double your working or playing time.

The case weighs 2 7/8 ounces. You charge it with the supplied USB to Mini USB cable and the battery will output 5 VDC at 1 Amp. The fit to my iPhone 5S was perfect. The battery has a push button on the back and if you quickly press it a LED bar lights up and shows you the power charged capacity of the battery pack. If the LED bar is green then the battery's capacity is 60 to 100%, if it is blue it is between 30 and 70% and if it is orangey red it is 5 to 30% and if it is flashing orangey red it is less than 5%.

To charge your phone you press the button on the back and hold it for 3 seconds. Your phone will make a tone and start charging. When your phone is fully charged then the process stops. You can also stop the phone from charging by pressing the button on the back again for 3 seconds. The ideal thing is to use your phone all day long and when it is low then press the button on the back of the case and charging begins. Charging will not begin automatically, you must press the button for 3 seconds. It will charge your phone quickly. My video shows the case and how it works.

I got a new iPhone 5S. I am a reasonably heavy user and based on my usage, my battery would last for 8-10 hours. I needed it to last at least 14 hours. uNu works great. Installs perfectly. The screen guard that comes w/ the case is OK. It has some glitter like feel which I am not particularly fond of, but it protects the screen. I am thinking of getting it replaced with armor guard from the mall.

The case itself is good. The battery takes 6-8 hours to charge for me which I think could have been better. The design of the case around audio jack could have been better. Carrying around the extension cable is an overhead.

When taking the case out of charging mode, it automatically charges the phone. So every morning I have to manually take it out of charger which is a nuisance. I had hoped that it would not automatically charge the phone in this scenario.

When the iPhone is installed in the case, it doesn't automatically charge the phone. I like this part.

[[VIDEOID:mo3LELN77Q8I1Z8]]My video shows the blue, silver, gold and black battery cases.

What's in the box:
-uNu Power DX 2300mAh battery case for iPhone 5
-micro USB cable
-headphone jack extender
-screen protector
-user manual

Review:
This battery case is great and provides enough power to charge my iPhone 5 105% in my test. The feels great to the touch and the surface does not attract finger prints. I can charge my iPhone 5 and the battery case overnight and both will be full by the morning and be ready to serve me enough power for the whole day. The iPhone 5 does not move at all in the case. The volume/lock buttons and silent switch are very easy to get to and activate/ press. The camera does attract some dust overtime but is very easy to clean. The camera flash is fine to use with this case (No colorful reflections). The case has a very small lip so the iPhone itself does not physically touch the surface when the screen is face down. It uses a micro USB cable (used by most smartphones today) to charge the case and iPhone. I can use this with my iPod touch 5 but is loose inside the case because of the thinness of the device but will work to charge it if needed. This battery is confirmed to work with iOS 7(MFi certification).
Overall this battery case is the best case I have ever had and I recommend this to everyone with a fast depleting battery or just want the extra power/feel the need to have extra power if needed (that's me).

I bought the black color. The gold, blue and silver colors were samples given for review. My review is my honest opinion.

Matte finish is nice, but plastic buttons and top of the sliding case feel cheap.This case provides more than double my iPhone 5's battery life and I am able to use my phone for the entire day and still able to carry a full health iPhone around at night!If you have a screen protector installed than it will not hinder the install of the case. Other than that this is an absolute awesome case. I had the case charged in a few hours, used it and charged my Iphone up to 100% pretty fast. I can get at least 2 charges from one battery charge when my iPhone is at 40-50%. The volume and power buttons work well through the case, and the location of the charge indicator lights and power switch for battery on the bottom of the case work well. I got the matte black case and the finish of it is sleek. I like how it has a function button where you can turn the battery on and off. The phone is flush with the case itself which makes it fit perfectly in the case.
