Should I Buy?

[Android Central Question]

I've been considering getting a new phone for a while now as my S8's battery life has fallen off a cliff and the screen also has a minor crack.

My Xperia Z3 is probably my favourite phone I've ever had and I've always been tempted by going back to Sony. I've heard some brilliant things regarding the screen but wondered if anyone could tell me what the camera and battery life are like on this phone? The S8 has a very good camera and I would want something that is at least on a par with that.

I'm toying with the idea of getting this or waiting until April for the P20 Pro's successor. Would really appreciate any user opinions of the XZ3 to help inform my decision.
