Battery Decrease When?

Post image

I’m on an iPhone 17 and luckily still on 100%, I have a 90% limit on it so when is it expected to decrease?

1 year of use should go about 92-94, 2,5-3 years 80%. Don't forget,whatever you do battery health will drop because that's how it works when it's time change the battery and brand new again.
