Is fast charging (20w) on daily basis impacts battery life? I bought my iphone in December 2020 and now battery capacity reached to 94%. I read it somewhere that battery needs to be changed if it reaches to 80% capacity.
iPhone 12 mini, iOS 14
You can damage the battery if it goes to "zero" and stays there for days. This is because at gauge zero it still had enough power to start up charging, but after some days it can go to actual zero and you will be in trouble.
Anything else is myth. There is no point in worrying about battery "health" (which is just capacity relative to new capacity) if you only use 60% of it between 20 and 80.
The phone itself will not be damaged by charging practices.

Yes have Apple fit a new battery at 80% ($69) though even then you will probably not notice any performance problems.
94% at 10 months is actually very good.
Fast Charging does not hurt the phone at all, the phone controls the charge current as it needs it. Best practice is charge every night all night so that Optimised Charging kicks in as in the graph below...
Thanks LD150 for your response and explanation. One more question on this line, will it cause any issue to battery if we charge beyond 90%. I read somewhere not to charge any battery beyond 90% and never let it fall below 20%.
As I said "Best practice is charge every night all night so that Optimised Charging kicks in as in the graph below..."
As you see in the graph it will hold steady at 80% then finish to 100%
You can run it below 20% but don't let it run flat. There will be reminders at 20% and 10% to turn on Low Power Mode.
No it will not hurt it to charge it past 90%. Do you have optimized charging turned on?
Yes I have it. But will battery life impact if it falls below 20% and we don’t charge phone?
Fast charging
