I purchased a Nokia DT-900 charger for my DNA about a month ago. Has been working great, and love the convenience. I charge every night while sleeping. I pulled the phone off the charger this morning and found my battery was almost drained. I put the phone back on the charger and the notification came up on the screen that wireless charging was enabled, but a few seconds later it reported it was disconnected. Tried that several times with similar results. Finally figured out that if I put a little weight on top of my DNA (TV remote), it would stay connected. Has anyone else run into a similar problem? I don't know if it indicates a problem with the charger or the phone since I don't have a second of either device.
