yes, because you are using the fast charge way
NO. That has nothing to do with it at all.
Form respected forum member Lawrence Finch:
Your battery capacity is not measured in weeks or months, it is measured in full charge cycles. One full charge cycle is discharge to zero, then charge to 100%, or any combination of charges that total 100% (for example, charging from 30% to 80% twice). It is spec’d to stay above 80% for 500 full charge cycles. That works out to about 25 full charge cycles for each 1% drop in capacity. So depending on how heavy a user you are that may be a reasonable number. You should only check it after charging to 100% and right after restarting the phone; that is when it is most accurate. If it reaches 80% while it is still in warranty (one year basic, 2 years if you purchased AppleCare+ when you got the phone) Apple will replace the battery for free. Outside of warranty the cost is $69 for an iPhone 11.
