My maximum capacity goes down fast

I got the iPhone 13 for my birthday (5 December 2022)

It only got to 99% in May

I went in a holiday this month and when I checked my capacity I saw that it got to 94% already and when I left it had like 96%

Can the heat damage the battery and make it go down so quickly?

iPhone 13

Hello lexi_i!


Your Maximum Capacity is doing a little better than average. You have nothing to worry about.


r.e. what causes the Maximum Capacity to decline, that cannot be determined.

Have a nice day, and good luck!

So, the phone is about 9 months old at this time.


Over longer periods of time, the Max Capacity of the phone will decline at an average rate of about 1% a month. That's an average. Some months it might not decline at all, then suddenly decline 2% the next month.


This is normal. Going on averages, the Max Capacity of your phone should be at about 91-92% at this time.


If the phone is at 94%.....as you say.....you are doing better an average.
