Apple Intelligence is now available on iPhone, iPad, and Mac!
Hi, I'd like to ask. I have an iPhone xs max over 3 months and my battery capacity dropped to 99%. And after a few days, it dropped to 97%. I think its weird, because the phone's only been in use for about three months. Please, do you know what to do with it?
iPhone XS Max, iOS 13

"Maximum battery capacity measures the device battery capacity relative to when it was new. A battery will have lower capacity as the battery chemically ages which may result in fewer hours of usage between charges. Depending upon the length of time between when the iPhone was made and when it is activated, your battery capacity may show as slightly less than 100%. A normal battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles when operating under normal conditions." [Source: Apple]

Normal and expected behavior.

You can't overcharge an iPhone battery.
Don't worry until the battery health drops below 80%.
