Warning to anyone interested in the Nokia CP-627 cover for your Lumia 830: it makes the wireless charging experience much worse. Both my Nokia DT-903 and my CR-201 chargers have a lot of trouble detecting my phone now. Last night, I thought my phone was charging (the DT-903 light was solid), but it didn't charge my phone at all. It's a huge pain. Strangely, I also have a QiStone+, and it charges the 830 with the CP-627 just fine. As nice as the CP-627 flip case is, I'd rather have wireless charging that works reliably, so back to the regular AT&T back plates for me.
