As Lumia support line ended, is it sane to keep using it for long? If I don't use anything except making basic phone call, sending text message, listen to music, watching videos offline, and taking few captures of library book pages etc?
I am thinking about disabling everything (even uninstall safely if that is possible) except those I want? I know browser would be useless in this fast moving modern web technology, and SSL will be a thing too....
I never use any web applications except browsers. My Lumia 640 XL battery still lasts like 4-5 days after a charge.
