And I've wanted to wait at least a week before I wrote anything but for the price it's a good deal but I don't know if it's my case or the case in general they kind of have a mind of their own and you need to pull it out of the case and then put your phone back in for it to be able to charge it which can be a little difficult as it seems impossible to pull your phone out of the case as it's a very snug fit which is good but there's little leverage you can grasp the iPhone to pull it out of the case. I'm sad to say that I probably am going to continue looking for another case that will not have any problems as I have taken my phone out and pushed it back in the case several times that my screen is coming loose and I'm scared that it's going to just slide off my iphone one anytime now ### ⭐⭐⭐ Works great for a few months... *by F***S on Reviewed in the United States on August 5, 2015* I got it in March and it worked great until a few weeks ago and now it won't hold a charge that well or charge my phone simultaneously. I've even tried different wall plugs and micro usb cords. Nothing has worked. It's the case. I'm not surprised though considering how cheap it was. Might recommend spending more on a Mophie so it will last longer though. I'm about to. ### ⭐⭐⭐⭐ This works amazingly well and I think better then a Moohie for much less than Mophie's retail ... *by R***B on Reviewed in the United States on May 21, 2015* This works amazingly well and I think better then a Moohie for much less than Mophie's retail price. My only nitpick is the surrounding case should be a little more beveled to protect the actual phone from shattering. Not that that has happened, but it looks like it might not protect the phone if it drops face down (neither does the Mophie, as a matter of fact). Still, I'd recommend this case in a millisecond. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/13059669-iphone-6-6s-battery-case-janx-apple-iphone-6-4](https://www.desertcart.pl/products/13059669-iphone-6-6s-battery-case-janx-apple-iphone-6-4) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-23*
