I received my S8 on Wednesday, and its standby drain has been pretty good, only going down a few percent in the night. Suddenly, my battery dropped down from 91 to 77 in 7 hours last night, and Google App was #1 on the drain list. I always set up Google Assistant the second I set up my phone, so I can't think of a reason why it would suddenly be draining- Samsung disables the damn app from always listening with the screen off anyways. Has anyone else experienced this issue and have any ideas? On the V30, the phone drains 10% in 24 hours on standby.
