I have been using this case for around 3 days now with no hiccups so I feel I can post a proper review. This is one of a few battery cases I have for the 6 that I am reviewing and I think its one of my favorite.. ZL managed to cram almost 2x the battery of the iPhone 6 into a pretty durable case that can survive a drop or two. The case itself has a nice matte finish so it adds some nice grip to the phone. ZL has a small logo on the back which is screen printed on. I believe the logo will wipe away with some alcohol swabs if you are looking for an unbranded look, but being its so minimal I decided to not bother removing it. ZL makes 2 different models for whatever reason and this is the bigger cap of the 2. Included in the nice looking box you get a headphone extension cable (you will need this if you plan to use the Beats by Dre w/ the angled plug, some instructions and also a warranty card. I have never had to use a warranty from ZL in the past but from what I understand its a pretty pain free process!!!!! I started my test by letting my phone completely die down and shutting off, I then applied the ZL case which I let charge overnight. Once I held the button down on the back of the ZL case 4 LEDs lit up and begin to charge the phone. It look roughly 1h 40min to go from a dead iPhone to 100% using this case, and in the process I dropped from 4 LEDs to 2 LEDs leaving some good juice left on the case. I then shut the case off (if you don't shut it off it will continue to provide power to the phone like a power source would). I then charged the case again to get 4 LEDs so that I was starting with a 100% charged phone and a 100% charge ZL case. I then used my phone as a normally would and once I reached 10% warning I fired up the case by holding the button down again. I continued to use the phone normally this time letting the case just stay on as I used the phone. I was able to pull just over 3 days total out of the phone and ZL compared to just 1 day without the ZL. Obviously everyones results will vary based on personal usage of phone and what all options you have as far as power saving measures. A few important things I would like to point out.. 1) It does add noticeable weight and bulk to the phone but thats to be expected so you can't knock any points off for that. 2) It does add protection to the phone as I did drop it at work on accident 3) The phone does seem to get a little warm being wrapped in the ZL when your doing a lot of stuff on the phone, but nothing too hot. 4) If you are a music listener this case also helps the speakers shoot directly towards you so music sounds louder. 5) ApplePay STILL works with this case, there is another one I tested recently that would not allow ApplePay to work for whatever reason. All in all this case is totally worth the $50. Why pay $100 for a Morphie when its pretty much the same thing minus color options. I saw previous reviews bagged a little bit on the color. To me black is fine because this isn't a daily case for me, rather a case that I will opt to use when I know I will either be heavy heavy on the phone (like recording videos at family events or concerts) or when traveling to downtown where signal quality is an issue which causes your phone to drain quicker.
