Honestly, I "upgraded" my phone to the 8 year newer model, and besides the easy numbers like CPU speed, RAM, and storage, it's a straight downgrade. No headphone jack, slower charging, 50% chance of worse battery life (something slurps like mad sometimes), a hole in the screen, fewer buttons, a bunch of my apps don't work anymore, fewer sensors, worse case selection, fatter & heavier, and the big G won't stop pestering me to install malware.

I still use my old mobile more. It really just needs a new battery and some extra RAM.
