Battery Health declines about 1% for every 25 charge cycles.


43 charge cycles divided by 25 = 1.7%


So, your Battery Health would normally be 98.3% at this time.


Apple will display this as 98%, because they do not show tenths (.3%) in the Battery Health report.


Your battery is performing normally.

Apple specifies that the battery is good for 500 charge cycles before the battery reaches 80%.


500 Charge Cycles divided by 25 = 20%.


So, after 500 Charge Cycles the battery will be at about 80%


If you feel that your battery is not performing normally.....(I think it is)......please make an appointment at the Apple Store or take the phone to an authorized Apple service shop and they will confirm that what I say is accurate.
