So I'm stationed in Germany and I went and bought a European charger for my iPhone 6. When I plug it in, the battery percentage goes slower than I've ever seen, and in fact it actually goes DOWN if I'm using the phone while it charges. Worst of all, the charger gets VERY hot in just a few minutes. I'm still using the same USB cord as I did in the US but I doubt that could be the problem. Wtf is wrong with your electricity, Deutchland?
