Battery Drain Problem

Hello all, I got Vivoactive 5 and it sometime drain battery by itself. I just charged yesterday afternoon and it drained %35 in my sleep. Normally it’s just %2-3 max 4 but after update it drains anormally and it making me so angry. I’m user of Garmin like ten years but I really start to hate because of this watch! Please solve this problem or I will buy Apple Watch or Fitbit it’s just frustrating 

last night my battery was %100 now %62!
