Even the giant plus-sized iPhones run out of juice eventually, and that goes for the new iPhone 8 as much as any iPhone before it. You could carry a charger with you and spend the day hunting for available wall-sockets, but these days that’s as lame as using dodgy free Wi-Fi instead of reliable and fast LTE. Instead, you should take some backup power with you. There are two options: battery cases, great for really heavy phone users who always run out of power before lunch, and a spare battery with a USB cable that can charge your iPhone, or any device, but stays in the bottom of your bag until it’s needed.
Let’s take a look at the options. There’s also one very cool surprise feature in one of our picks that “wireless” charging fans are going to love.
