Great Case, Bad power button

The Anker Ultra Slim iphone 6 Charging case works perfectly and will give your phone nearly double the battery life. I used the phone case as I traveled across Europe this summer and it was very convenient to have as I was not restricted to power outlets in the airports or in my hotels. I really enjoyed that I could go nearly 2 full days without even having to plug in for a charge. The case will continue to charge once the phone reaches 100%

[UPDATE HERE] So after I wrote this review, Anker contacted me, felt that I had a warranty type problem, and flat out replaced the charger….BOOM!!! Like I said in the review, the thing is a GREAT charger on the road, (and I’m on the road a LOT), so I know, I’ve used the thing relentlessly and it works great, plus it’s seems like it’s not much bigger than a regular case that hugs the iPhone tight…easy in the pocket. So I’m changing my review to 5 stars, cause if the thing is great, and the company backs it up when it ISN’T great, then that’s 5 stars to me! [End UPDATE]

I bought this back in April and I loved it. It’s got that soft smooth matte feel to it. It kept my phone from being damaged when I set it down on a table, and the extra battery life was a godsend when I was out and about without a way to get to a plug. I’ve bought several things from AnkerDirect (for family members etc) and never had a problem with them. I do agree with people who say the charge button on the back is a bit sensitive. I have found it turned on from just me sticking it in my pocket, but it’s not a big deal. I just turn it back off.

after almost a year of daily use the case has cracked to the point it no longer stays together (without generous amounts of super glue). The phone has not taken any significant …

I received the Anker battery case today, and it works as advertised. It is lighter than the Apple iPhone 6/6S Smart Case and about half the price. The Anker case is solidly built, and it is pretty easy to remove the iPhone out of the case if needed. It is also pretty easy to grip the case when holding it on the train or bus while standing, since the case’s surface is not slick.

Best battery case I have ever owned.

I have owned several battery cases in my time. The job I have keeps me outside all day and then some, so one battery cycle on a phone just isn’t enough to cut it. I have used life proof, otter box, and some other brands but have not found a less expensive or better battery case.

I can’t say enough good things about this company. Finally a company that believes in customer service. I had issue with the charging port. I thought it wasn’t working. I tried a few other cords and still couldn’t get it to work The company reached out to me when I commented that I was having issues. They convinced me to try one more cord and they were 100% correct it was the cord. I just happened to have two cords that were junk. When I replied to them I told them thank you and even though I dropped my case it had chipped a bit at the charging port area. They asked that I send them some photos. They believe in their product so much they said even though it wasn’t and issue with the product they wanted me to be happy and mailed me a new case. They asked that I return the old case with I gladly did. Each email I received was kind and courteous. In addition this product works great. I use my phone a lot and this extended battery easily charges my phone and keeps it going all day and night. Thank you for a great product and amazing customer service. I will purchase your products again and again.
