My iPhone is charged 594 times but the battery health is 98% is it normal?

That is certainly unusual; it would mean that the battery in your phone far exceeded the minimum specifications for an iPhone battery when new. Specifically, the battery’s initial capacity was about 25% higher than Apple’s minimum. Batteries, unlike iPhones, are nasty analog devices rather than neat digital. Apple specs the battery capacity to remain above 80% for 500 full charge cycles, but that is a minimum requirement; there is no published maximum expected capacity, and some batteries do better than the minimum.

All iPhones have a specification for the battery. As an example, for the iPhone 14 Pro that is 3200 milliampere-hours (MaH). So the battery monitor is calibrated for 100% at that value. But there are variations in manufacturing, so some batteries will have less capacity, and some will have more. Suppose your battery had, say, 3520 MaH capacity (10% over standard). That would still show as 100% (even though it was actually 110%), but as it aged the health would stay at 100% until it fell below 3200 MaH. This would appear to you as if the battery had fabulous life, until suddenly it didn’t.

You are saying the phone reports 594 charge cycles?

If that is true, you would expect that the Battery Health / Maximum Capacity would be in the 75-76% range.

If you see a reading of 98%, that cannot be correct.
