Wireless charger won't fully charge my phone

[Marty89]

Hi, I have a new Galaxy S7 edge. For night charging I've been always using my Microsoft DT-904 fast wireless charger... First weeks were good, everything worked but now I always wake up to my phone being not fully charged sitting on 70-90%. And the charging is always slow, even though the charger is claimed to be a fast one, I also use samsung fast wall adapter. Can anyone help with this issue?

Fast wireless charging is a setting option... Did it get turned off by any chance? Also, when placing the phone on the charger, you should see the notification if it's fast charging it not. Lastly,vthe adapter has to provide the voltage and current for fast charging (9v/ 1.7A) - if you have one of those USB passthrough meters you can check. I had a Chinese adapter dropping to 5v after a few months ...and never got past 5v again.

I use Samsung fast charging wall adapter. And no, never saw fast charging option. My Lumia always charges fast. About 2hrs with its 3340mah battery.
