@reflex I'll kinda follow that, but I let the phone do that for me. I use the advanced charging controller module. Its telegram channel: https://t.me/acc_group
Whenever it gets down to the 30s if there’s a charger available, but only to around 80. This ends up being once or twice a day depending on usage (i sometimes watch hours of videos while doing chores and that sucks my battery).
Mostly once per day in the late evening before bed or at about 15% whichever comes first; have battery protection to stop charging at 85% as I want to avoid battery degradation.
