Might be I was just lucky with few devices I owned over last 5 years, but I only got problems with them after putting them in some insane conditions like living in Asia with constant overheating, sand and sea all around. Though I only ever used Cyanogenmod / LineageOS and specifically was looking for older, but tested devices that work well with custom firmware.

Also when it's $160 device I don't need to worry about randomly died battery because I can always get new phone.
