So coming from a Note 7 and various other phones(OP3, HTC 10). If I left my phone on my nightstand overnight at 100%, typically from 11pm or so to 7am, I would lose anywhere from 5-10% battery. With the V20, I was shocked to see it was still 100% at 7am!
Screenshot is after I started using, but you can see from the graph...pretty impressive!
