The problem I have is EVERYTIME I do a software update it causes chronic battery drain! This causes me to not want to update! I have a Galaxy s7 and just did the Valentine's Day update and now have the same issue! Something, or some things, must be adjusting at every update. I have to go through all the settings, notifications, and apps, etc., until I find it or them by luck! I can never tell what makes it better. It's way too time consuming and extremely bothersome. I used to love my Samsung's, but my next phone may change brand. Very disappointed.
