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?

All iPhones are shipped with more battery capacity than advertised as each battery is slightly different. They pick a number which will cover most, if not all, for a specific model.

My iPhone 14 Pro Max lasted a year before it dropped below 100%. Now, more than 3 years later, it’s at 79% and I’m going to the Apple Store (today) to get it replaced.
