In this video we will be having a closer look at super fast charging that your phone can do. In this mode your phones battery gets charged up with 5A of current that makes it possible to fully charge it up in one hour. Normally your phone charges with 1A and that got me thinking how much your battery suffers during such super fast charging. So I spent way too much time making a testing circuit and then super fast charging batteries 100 times to find out whether there really is a difference noticeable ;-) Let's get started!
