I have the 9 Pro and I only ever used wireless charging when I first got the phone. It was a cool gimmick for a couple weeks. Now I just plug in my phone when I need to charge it. It's faster and more reliable. The only use my wireless charger gets now is when my boyfriend comes over and needs to charge his phone overnight, because he has an iPhone and I don't have any lightning cables.
My OnePlus Open is supposed to arrive this week and I'm not going to miss wireless charging one bit. I can't even remember the last time I used it.
I'm convinced their username says "its no tits" and no one can convince me otherwise
