Kotech iPhone 6 6s Battery Case Ultra Slim Extended Charging Case External Battery Case Portable Charger for iPhone 6 6S 4.7 inch with 2400mAh(White)

Great customer service from Modernway in response to my original review. They offered to replace the Kotech iPhone case above with the Modernway iPhone 7 Battery case 5200 Mah rechargeable Battery case. I can tell that this case will provide the added charge I need for navigation purposes. The case is very similar, black and white and extremely attractive. It is very easy to install the phone into the case. Modernway assured me that this new iPhone 7 case is compatible with the 6 iPhone. I look forward to getting great use out of it. The printed instructions leave something to be desired as the translation into English is not very clear. If I have any wuestions I will contact the website. There is no front cover so you will need to get your own screen protector. I am using one I already had so no problem.

Life changing upgrade. No more plugging in your phone all day or worrying about your battery. Works great, is slim considering what it does for you and is well built. I had some trouble with the first one I purchased (it stopped taking a charge and was acting wonky) but the seller worked with me and got me a replacement asap so I still feel confident to leave 5 stars since I've had no trouble with the second one and it is such an improvement to have my phone charged all the time. We traveled to Thailand and this thing came in such handy while site seeing all day. The best advice is to turn the battery case on as soon as possible once the phone is fully charged. That way the charge drips slowly, keeping your phone at 100% all day (even when using a million apps a day and bluetooth like I do). If you let your phone go down to less than 60% then turn it on, it will fully recharge your phone but then that will wipe out the extra charge life since the thing is working harder to get your phone back up there in battery life. IT's a life saver either way but nice to have a fully charged phone allllll day when on the go.

I loved it! :-)Purchased in July (color = black) — slim design, had enough power to keep my iPhone 6 charged the entire day (which was always problematic previously).But, all of a sudden, stopped charging properly on December 1, leaving me power-less.Very disappointed. :-(============> 12/9/17 Addition to original post:The product distributor contacted me and provided the following [edited] steps to reset the case, with the case re-installed on the phone:1) Please [insert] the Apple Original Headphone and lightning cable [into the phone and case respectively]2) After insert[ing] the headphone, please press the ON/OFF button on the back of the case, then wait about 5 Seconds [for the product] to start workingThe product seems to be working properly for now, so I increaded my rating from 1 star to 3. (“No problems” would have given this product a 5.)============> 12/17/17 Addition to original post:Stopped working again. Performing “fix” again (several times) did not work.Very disappointing.Downgraded rating back down to 1 star.

Really like this case; lots of reserve power, great looking, and nice smooth finish which makes it easy to slide in and out of pockets. Battery adds a tiny bit of weight, which is to be expected, but I hardly notice it. Particularly useful if you use your phone often. Over the past seven weeks the reserve battery power has proven useful for me multiple times already. Recommended.

Extremely attractive case, slim, sleek. A bit slippery to hold which could be improved with a band of rubber, silicone or texture on the back. I have an iPhone 6. First use I was at 37% charge remaining. After case charge was complete I was at 87%. Fifty% is not bad compared to nothing. I would have given it 5 stars if it brought the charge up 75%. It gets 4 stars because the case uses the same iPhone cord, has pass through capability to connect to iTunes and does not require an extender to connect headphones.

I bought two in late 2016. The first one for my daughter stopped working a few months in. The second one just stopped working. Disappointing as I liked the case a lot. It’s fairly slim and looks nice! Now, I’ll have to look for another case that doubles my battery life and can be charged with the lightning cable.

I wanted to love the case but it needs protection around the top corners. Otherwise it would be 5 stars.

it does not give a full charge when turned on to recharge phone battery. It gives enough charge so you can get to an outlet and plug it in.
