I want to say that I LOVE my mobile. It's been outstanding since 2017. Great screen, great battery life, no ads or other BS— just very easy UX. Xiaomi Mi Max 2.
It is unstoppable & I LOVE IT in all regards EXCEPT, it doesn't have 4g 700mhz band 28.
I cannot understand why all phones went to the stupid skinny ratio, but I need a new phone. I don't want a flagship. My prefs are:
Good battery life
mSD
3.5 jack
stereo speakers if available
What's my best bet?

The newest phone appears to be the Xiaomi Redmi Note 13. JB HiFi is back to selling Xiaomi phones now so you can buy locally too.
