I just did a search to see if I was the only one having this issue. The battery went from 92% to 24% overnight with all apps closed and an extremely strong 5G WiFi signal throughout my home. I have tried uninstalling apps, deleting any content on the tablet. I even turned the tablet off overnight last night and it still dropped from 89% to 82% with the unit POWERED DOWN COMPLETELY! I never lost that kind of power prior to this with the unit on and apps still running.
I don't know what has happened, but I can no longer rely on my tablet to run long enough for a cross country plane flight without absolutely needing a fully charged mega charger to be the supplemental power supply. OK for a plane flight, not ok for everyday use. Can someone please explain what's happened to the great battery life that my tablet once had?

Same problem here.
It was fine with Marshmallow. Long battery life. Easily 3-4 days with active use. Now, I cannot make it through 24 hours with similar use. If I forget to charge it one night, the next morning, the device is out of battery. I might just ebay this off and get an Asus (gasp!).

The problem started last week or so.
I used to charge my Galaxy tab S2 about once a week and now without any applications running, Wifi turned of and no activity what so, my Galaxy tab S2 goes from 100 to zero in about 14 hours.
