iPhone battery capacity
i purchased an iPhone 11 on May 24th this year. Lately I’ve noticed the battery capacity in settings is currently at 97%. It went down 3% in more than a month. I don’t fast charge unless I’m in a hurry. I’m a heavy user but my battery still lasts a full day and I only charge it once a day before I go to bed. I also never let my battery go below 20%. Any suggestions?
iPhone 11, iOS 14
