Whenever its below 20% or when I sleep
Handily my phone can use the same chargers that we use for laptops on our house, and as the charge is fast, and battery capacity good, I don’t bother charging it at night unless it’s low. Before this phone I’d charge every night. Some sort of progress.
Whenever it’s getting to about 30%. I also use slow charging, and since most of the time I am near a charger, it’s never a problem. I often wake up with my phone at 35%, I plug it in before going and most of the time when I go I am at 70%.
When I sleep and when I drive.
About every second night. I normally use 20-40% per day so sometimes I charge every third night.
I only charge overnight and during my 15 min commute while using CarPlay. My phone never falls below 60-70%
my phone takes about 20 mins to charge completely and i charge it once every 2 days, in the morning while I’m doing my morning business.
If commuting, I take public transport so charge on last bit of journey before (or after work) if needed or a heavy phone day.
At home/weekends - whenever it drops and I have time.
Mini is whenever. I have fast chargers all over the house, in both cars, at the office, and a power bank too.
