A few days ago I began to notice that my phone wasn't fully charged after being attached to the Wireless charging Orb all night. It doesn't happen all the time, but what I found out is the phone stops charging after around 15 minutes when on the Orb. I am running the latest nightly of CM10.1 so I'm not sure if it's just a bug considering it was working fine when I first got the Orb. I also just put on an invisashield on the back and front of my phone.
