Hello community, I wanted to ask which is the best way to charge my iPhone battery (the most healthy for lifetime). From 0-100% or from 20% - 80% . Also I have noticed that not matter if I charge the first way or the second , still battery cycles is adding always+1
iPhone 12, iOS 15
You can do ~20-80% if you want to monitor the charging, certainly won't hurt anything. But you'll get a little less usage out of your phone before you have to connect and charge it again.
Plugging your phone in overnight and leaving it plugged in, having Settings > Battery > Battery Health > Optimized Battery Charging turned on is what I believe the official recommendation from Apple would be. That would allow your phone to 'learn' your habits. Mine for example charges to 80%, then brings it up to 100% by about 4-4:30 in the morning because I get up a little after 6:00. It even comments on the Lock Screen when I go to bed when my alarm is set and what time it'll do the final charge top off. I believe what is hard on the battery is if it were fast charged from 80-100%, not actually being at 100% charge.
I definitely would NOT allow the charge to go down to 0% though. My understanding is that it's hard on the battery. I don't allow my charge to go below 20-30%.

LiPo batteries don't like to be discharged down to 0%. However, i think the system will shutdown before. My experience is, LiPos "like working" - not holding on charging line over days. Do so, it kills the battery life cycle in any months. So, charging up to 100% and let work ,maybe down to 20%.
