I am experiencing an odd problem with wirelessly charging my phone. When placed on the charger, with about 40% battery. The phone 'binged' to let me know it was charging. ~8hrs later, the phone was dead. I know the phone has a great standby time. So even if the phone wasn't charging, I would expect that with no interaction, that it could last 8hrs at 40% battery. Any thoughts as to what may be draining the phone dead? Interestingly I toggle the phone a bit on the charging 'pill' (rotate 20deg and then back) and it begins charging and almost immediately starts the boot up process ... unlike when you really use up all the battery in a phone and it charges for 15 or so min. before booting up.
I Have the "battery level for wp8" app and it shows a drop in charge from 49% at 1am to 10% at 7am. After charging it in the morning for 20min, it got up to 30% (at 9am and until now 1:30pm) is still at 20%.
