Samsung S6 battery drain

Hello,

I was wondering whether someone can advise. I have a new S6 but the battery life is terrible. I have Googled the issue and followed all the advice I've found but it hasn't solved my issue.

Despite my screen on time being only 47 mins, my battery was at 39%, is this normal (this is the first android phone I've owned!)

I haven't used any social media, I haven't watched any videos, played any games, listened to music, or made any phone calls. The phone has basically been unused...
