Moving from iPhone 5 to Oneplus 3?

I havent got the oneplus 3 yet
But i am planning to buy it
I am afraid of the battery performance to be bad compared to my iphone 6s plus.
Those are my results, as always ymmv. I run a ton of apps and have lots of email accts., social media and take a lot of photos. The iPhone 6S plus has great battery life for sure. This is just working better for me. Hope that helps.
