If it last a full day with my current usage. I am more than happy. I'm sure when I'm home it will last me a couple of days. My LG G4 when I leave home was flat by 12:00.That's quite heavy usage. It easily lasts me 2 days and more since I only use it for WhatsApp and a few important calls. Your brightness is too high it seems - it's chowing the battery.
My Note 4 lasted the day easily, but not much I could do on it.
