Old phone? I'm still running a Mi A1 as my daily. I'm on LineageOS 19.1. There have been rumblings of Lineage 20 coming to it, but the Dev community has largely dropped off.
I'd check if there are any local high-schools or support services that are looking to get phones intot he hands of underprivileged teens/adults. A Mi A3 is likely still better than the low end Samsung garbage, or even an old iPhone (below X).
Better to have it be reused than become a paperweight in a cupboard.
Howdy Neighbor, you could always move a little further north. We've got lots of people driving EVs up here in Winnipeg! I'm kidding, but there is at least some charging infrastructure coming rurally here in Manitoba, and you are starting to see a lot of commuters using them for 100+ km (one-way) commutes. That being said, we have similar issues if you need to drive long distances between rural centers, but the government subsidies to help install L2 chargers seem to be making a difference as more and more municipalities are installing at least one charger somewhere. I can understand how people are still hesitant about winter, with -20C (-5f) to -30C(-30f) being not uncommon (for now...).
