Battery Case for iPhone 6/6s, 4000mAh Portable Charger Case, Rechargeable Extended Battery Charging Case for iPhone 6/6s(4.7 inch)-Black

My 6s has been shutting down regularly due to poor battery performance and this seemed a reasonable alternative than spending nearly a grand on a new phone.Firstly it seems to have magically partly fixed my phone. Since buying the case I’ve only needed to use it a couple of times a week. Coincidence or magic, you decide.The case itself is pretty good. Ok it nearly doubles the thickness of my Phone but I can get three full charges from 1% before it needs charging again. The case itself charges using the lightening cable which is handy though of course the phones charge port is in use while the case is on so you have to take it out of the case to directly charge your phone.My main minor issue is that the phone is a little sloppy in the case, there is a bit of side to side movement and after a few weeks use one of the clips to keep the top on seems to have failed, not broken as such just not any kind of positive click as it seats. The magnet seems to keep it in place though.Overall it seems pretty good. It offers a bit of protection, all the buttons work. It looks ok and charges my phone a couple of times. I’ll put some tape in it to stop the sloppy fit but I’ll be upset if I loose the top part of the case. perhaps I was just unlucky.

This product is a very excellent buy. The smart battery charging case can definitely give your phone charging protection. The case is lightweight and not too bulky, unlike others. The borders are nice and thin and the battery is slim. The battery case can be recharged using your lighting cable which is another plus since you don't have to scramble around looking for a micro usb. The sides of the case are not as durable and flap off like if it lost its glue. Overall a really good case.

I tried a 6000mah case, it was HUGE. I tried a 2500mah, it was slim but didn’t even survive charging once before running out of juice.This case, this case is the one. Enough power to charge my iPhone to 100% and still have something in the tank. It has the nice non-slip matte effect and looks classy. And finally, it has a built in magnet, ideal for car use of Spotify/maps/etc.A quality product.

Did not fit - phone rattles when in the case. The charging function failed after a week - pressing the buttons lit the LED lights but nothing else. Shame as when it did work it recharged the phone at least twice. Have sent back.

The product helped me a lot when I was travelling. After fully charged, the battery could support your iPhone for whole day. It’s easy to carry and doesn’t affect the feeling when you are holding. I highly recommend this one

It's very easy to put it in the mini lady bag and the car magnetic function is convenient to the driver. I don't need to take the charge and USB line in my bag. This one is totally enough.

This Battery Case is really a good product. My iPhone is easy to turn off automatically. This battery case save my life in the cold winter. Definitely recommend.

This case packs excellent storage capacity in as slim a form factor as can be expected.Depending on what level of charge you start from, it does not typically take the phone back up to 100% from one press of the button. Seems to charge up to a random partial charge, then I have to press the again to bring up another round.It can take two or three rounds of pressing the button to bring it up to 100%, which is annoying, but manageable, since the capacity is terrific.This is similar to the smaller 4000 mAh case that I own. When I had a problem with that smaller case readily sent a replacement when the plug slot was not functioning consistently.The extra weight of this larger unit is more than I prefer in my pocket, so for daily average use, I prefer the 4000 mAh size.
