A lot of manufacturers like to claim they make “thin” iPhone battery cases, but it’s really just a marketing gimmick. I’ve tried dozens of iPhone cases with built-in battery packs over the years, and despite having words like “ultra-slim” and “air” in their branding, most of them were still far too bulky to carry on a daily basis.
Enter the ThinCharge case by ChargeTech. The company sells the case as the “thinnest iPhone 6/6s battery case on the market,” and I have to say they might be right. I’ve been using the case on and off for the past several weeks, and I can confidently say that this is—by far—the thinnest iPhone battery case I’ve ever tried.
How thin are we talking? Well the case itself measures just 11mm thick. So if you consider that the iPhone 6s is 7.1mm thick, then the ThinCharge is only adding around 3.9mm of thickness, which is super impressive. Additionally, there’s no ugly chin to be found down around the Lightning port, like on most other cases.
Having said all of this, the ThinCharge is no where near perfect. I ran into multiple issues during my testing, including slow charging rates for both the case and my iPhone, as well as a finicky cover over the charging port and other annoyances. So is the thinness of the case worth these caveats? Read on for my full review.
