I am having a problem with wireless charging after the update to Marshmallow. The phone is saying that it is charging and the wireless charger indicates it's charging, but it never charges. I tested it today with 80% charge and after 2 hours it has dropped to 74%. Before Marshmallow it would have charged it to 100% in that same amount of time. Charging with a cable works fine though. When I look at battery usage, the two main process using the battery are Screen (36% of battery use) and Android OS (26% of battery use). Further, it is not resetting the time on battery.
I have tried rebooting the phone and clearing the system cache. I guess now I will have to go through the entire process of a factory reset AGAIN. That is a pain since you have to download everything again.
I have noticed on some other forums where other people are having this same problem. It is ONLY wireless charging that I am having problems with.
Is there any other suggestions on how to fix it?
