OE batteries are expensive. Buy off AZ and get mostly junkService life of Li-Ion goes down substantially based on amount of time sitting above 4.1xV. Unfortunately most charge to 4.2V for that bit extra runtime. Life based on depth of discharge is not so clear cut. I wouldn't try to make it a rule to discharge down to 20% then be in situations where you are running out of power so can't use the phone, unless you have a relatively high capacity battery and know its limits vs your use cases.
Just about any battery is replaceable if you have the tools, and for older folks, eyesight and steady hand to do it.
I think fast chargers are hard on batteries. The battery in my LG K20 was still going pretty good after 5+ years, and I think one of the reasons it lasted so long is it took 1-1/2 hours to charge it from 15% to 100%.Maybe babysitting a phone's charging is helpful with today's fast chargers. I don't use fast chargers.
