Re: Batteries are always a problem for phones.
"Which reminds me that couple of relative's Samsung flip phones which are so old that then don't even have year 2016 support in their firmware are still running fine off original 15 years old lithium batteries which do not seem suffered from any deterioration over these years."
Batteries are killed by repeated deep discharges. Those old flip phones could go for a week + on a charge, so someone who rarely discharged the phone to 50% would end up having significantly less battery deterioration.
