Good luck finding one, they’re becoming quite rare beasts 
My current phone is an LG G5 solely because it was one of the few phones left available at the time that still had a user-replaceable battery.
I may end up importing my next phone from China. As whilst many of the phones there also lack replaceable batteries, they don’t seem to have the wests “maximum thin size and as light as possible, sod the battery” industry-wide focus, and you can find models with near double the battery capacity of western equivilents
