Since the death of my YotaPhone 2 I'd been so unhappy with every phone purchase until I got a Blackview BV6600 pro.
The battery is enormous, both in capacity and physical size but I still only charge it every 2 or 3 days.
It has an FLIR thermal heat camera built-in. It's so much more useful than I imagined. I used it at work today to find where a mouse was hiding, I used it at home to find a hidden power cable behind a wall.
It's waterproof and shock proof and I can forgive it for not having an e-ink screen on the back.
