Encountering the same issue on my S6 edge.
I have my location & weather turned off and still, it drains 28% (100% drops to 72%) in 7hrs 33mins overnight usage/standby.
the default Battery Usage shows the following:-
Facebook 7%
GPSD 7% (why is this appearing even if location is off)
Google play service 4%
Android OS 4%
Google App 2%
remaining are 1% on screen & cell standby.
Appreciate if anyone could guide me through or refer me to any links that I might have overlooked.
I've being trying different setting from turning off the GPS, edge screen night clock every night & i noticed only a 3% overnight last saturday. I thought it was resolved, but today,it starts acting up again without changes on my setting.
My apps remains as usual
Shall I restart my phone & continue monitoring?
Is this an issue that I've to wait until a new fixes is released?
