Yes because 160mm is the tallest I want my phones, taller becomes annoying

You want to maintain battery health but store it without use for a time. Do what the factory does. Charge to 50% or 60%, and turn it off. Then store it. Best for battery protection and longevity if stored

Went from a Poco X3 pro 6.7 inch to a s10e 5.8 inch. You get used to it after a while and barely notice it.

Get a new phone when your current phone no longer does what you want it to, battery is really bad and don’t want to replace it, or just bored with it and can afford a new one.

Otherwise keep it. Getting hacked on Android really only happens if you install apps outside the play store, and even then not very often.

If you use banking apps there will come a point where they will stop support for security, but still could be a few years from now.

TLDR: if you are happy with the phone don’t get a new one. I know people who use phones from 2015 and are happy with it. (J7 series)
