my deal break is a battery that cannot be replaced by the user in 2 nanoseconds.
They hardly make phones like that anymore.
I have experience with Samsung Note 4 and the latest-greatest LG phone (about 2 years old) that can take a removable battery is LG V20.
yeah, it's dated meaning it's cheap. Still has tons of capabilities.
The other deal breakers for me are non 16:9 screens and the stupid curved edge. I am currently running Samsung S8 Plus and positively hate it. The picture quality is stunning however, highest resolution on the market I think. Retina display to the Nth degree.
I liked iPhone 8 Plus, it's the iPhone that meets 2 out of these 3 requirements: It's 16:9 normal ratio I can process and also no stupid curved edge. Sealed battery of course so that's that.

Nothing in the world scales well to 18:9, nothing.
It' just stupid as hell IMO..
Hell, I would pick a 4:3 screen ratio if I could. Like a mini-tablet.
back to the battery situation and why it's so important, see you can carry a spare full size ZeroLemon battery and if your primary is down, just install a fresh one and you are 100% without charging.
Charging may not be an option for 1000 and 1 reasons.
The fuse in your car blows for the 12V socket and you are on a long trip somewhere in the middle of nowhere. With phone coverage but a discharged device that's at 12% and beeping that it will shut down soon.
Or you are traveling. You bring your phone, the charger then realize in Europe you see they use those funky different style outlets and you need to buy a converter, and it's 1AM when your plane landed and all the stores are closed until morning and you must make a phone call / Skype to back home where it's 5PM and your phone is at 9%.
The real reason they seal batteries so that when it goes bad, you just upgrade the phone. Consider Samsung Galaxy Note 9 which is almost the exact same thing as Note 8 and S9 is the same thing as S8. Not a version change but more like a minor 8.1 release.
iPhone battery is just like any other battery and loses capacity after 2 years.
If you could upgrade just the battery, the phone could last almost forever, which in phone hardware terms means 5 years.
