POTENTIAL BUYER - Need some questions answered, thanks!

Hey guys,

So my Droid DNA is really starting to show its life right now, and my contract with Verizon ends this November and I'm looking to switch to an unlocked phone to use with a cheap carrier like MetroPCS(Tmobile towers)

I've been looking mainly at the Oneplus 2 like everyone else, but upon watching Phone authority's YouTube, i stumbled across this what seems to be a very amazing gem. I have a few questions that, I feel if answered with what I really want to hear, it'll definitely be a must buy later this year

1. The screen, its 2K so there's no issues with clarity, I hear the colors are very nice, but then I've heard a few reviewers complain about the brightness. How is it? How is the screen in general compared to a note 5 or iP 6+?

2. Will this even work on Metro? I mean, it uses T Mobiles towers so it has to work.... Right?

3. The heat. Everyone in the Android community knows about the heat of the S810, and though I've heard many people quoting Xiaomi mentioning their 5 heat patents, I've still seen people complain that the phone gets uncomfortably hot. Does anyone have any temperature readings?

4. And finally the battery, this I'm not TOO worried about, I'm sure the oneplus 2 would have a bit better battery life with its 1080p screen and slightly bigger battery, but lack of quick charge upsets me.

Thanks for all who help!
