Again, with normal use like texting / browsing / YouTube / social media both get great battery life overall but I still give the edge to the 8+. When you add benchmarking and gaming then the much more powerful CPU and GPU will obviously consume more power in the iPhone - it’s a pretty simple concept. It’s not like I chose to not use the iPhone or Note 8 as much as the other. So yeah, if you do a lot of gaming on the go and need the extra battery life, then the Note would be the better choice for that use case.
We could keep going in circles forever so I’ll stop but at least have an open mind to both sides - everyone who is replying seems to want to “win” and prove the N8 is superior in that department but I think if you really used both and weren’t so subjective you’d see what I’m talking about. Again, I think both are awesome phones in their own rights and battery life is a win in either phone relative to other choices.
