If you're cool with only using your phone as a phone + texting device you can get 5+ years out of current day non-smartphones and it only costs like $30 to fully replace it, so there's no need to swap individual components. My current phone's battery goes 3-4 days before I need to charge it, cost around $30 and it's currently been in use for 3 years with no signs of getting worse or breaking.
