Hi, I wanted to ask if someone of you already used Pokemon Go plus enough to decide if it's saving battery? I mean, game by itself is battery killer on the phone, so what about the device? Since the phone is locket, I assume that it doesn't drain battery that hard, right? Also wanted to ask where I can order one? I'm from Europe. Btw. I know they are sold out at the moment, but I'm planning to order one in a week or even more, so where do I need to check for that?
