The Quest for a Dumber Phone
the problem is not smartphone but people without self control<p>you can use smartphone exactly same way as dumbphone and still have smart features available when needed<p>problem with dumbphones is mainly horrible camera, so you would need to carry camera if you wanna capture something, smartphone with self control solves this issue, nobody forces you to use anything but Phone and Messages apps and you will still have great camera and GPS, which are both lacking  at dumbphones<p>if you use phone this way you should have pretty great battery life even with smartphone, you can choose some power efficient SoC combined with huge battery, for instance in Sony Xperia 10 IV, which is also relatively compact (narrow, but longer)<p>if you wanna save your time delete all social media apps and preferably also block these sites in browser, then also turn off notifications for everything but Phone and Messages, eventually Email if you need and your problem is solved<p>if you wanna go a bit more extreme you could use custom ROM without gapps, but honestly as someone using this config for almost decade I am hardly limited by apps because pretty much everything works even without gapps
