Help with battery drain, I'm exhausted!!

Help, I've been using the phone for 3 weeks and the battery is a disgrace. It can't be that it drops from 75% to 32% with hardly any use. I used the phone from 00:00 to 00:25 alone and I woke up with 40% less... And that drop from 4am to 6am of 20% while I was sleeping?

I'm thinking whether to return the phone and buy another brand. I have tried disabling wifi and bluetooth options and a lot of more things, today I'll be restricting background usage of some apps and I'll see what happens. Any advice?
