I have a 7 plus and an S8..7 plus I use for pleasure and S8 for business because it seems to work better with my VOIP app when I am not in the office. Anyway...during the work week, I am surprised by the battery life of the S8. Is it known to be better than the 7plus? My 7 plus was replaced about 2 months back...so it isn't super old. I didn't anticipate the S8 to last so much longer than the plus. I use both a lot during the day.
