Hi, I would like to hear some comments from you guys, i can't decide which should be my next iphone. I currently have a 6 plus 64gb. It's been really great but now i'm starting to feel it a little "slow" in the UI. Also, even though its size has a lot of advantages I stared to think that maybe I could go "smaller". So, long story short. I'm trying to decide between the SE, 6s and 6s plus. My two biggest concerns would be the smoothness (I'm starting to feel mine a little choppy) and the battery life (this is the thing i love the most on my current iphone). What do you think? thanks in advance.
