Waking up with S7 80% battery remaining, S6 was 90%.

Has anyone else noticed that going to sleep with a fully charged S7 results in waking up with 80% battery remaining? I used to sleep with the S6 every night and usually woke up with around 90%. Now I feel like I need to put it on the charger after I wake up because now at around 230pm the battery is at about 42%.

Same concern here. I am wondering what is draining the battery so much.
