What should iPhone battery health be with 543 cycle count?

For a 1.5 year old iPhone, regardless of cycle count, your battery health should be somewhere between 50 and 100. Maybe.

In other words, there is no accurate and reliable correlation between cycle count and battery health. The only reliable aspect of battery health is that it is going to go down as your device ages.

The best way to care for your iPhone battery is to not worry about it.

Which model phone do you have? How old is it? Have you ever had the battery replaced? Are you seeing something that makes you think there is a problem? If so, what?

Go to Settings>Battery>Battery Health. The battery capacity should be above 80%. Also, if the phone has detected any issues, you'll see a notification there that it needs service.

If it's over 80% and there are no other indicators of a problem, you should be fine.

my battery health is above 80% I know whats my actual battery health but i wnna know from you guys that what should be my battery health according to your guessing !!

I'm not really interested in playing pointless guessing games. If you're having an issue with your phone, please explain what it is. If your phone is working fine, stop worrying about the cycle count and just enjoy your phone.

In my professional field (research administration), the running joke is that answer to any question faculty asks will start with "It depends...."

it’s iphone 15

The battery will decline about 1% for every 50 Charge Cycles.

So, rounding off to simplify things, let's say that the battery has gone through 550 Charge Cycles.

550 divided by 50 = 11%

So, your battery should be in the 89% range

My 6 year old XR’s battery capacity is 92%. Lithium batteries don’t really age significantly over time, that’s why they put 10 year Lithiums in smoke detectors. It’s really cycle count that matters, not chronological age.

My oldest iPod classic still works after 20 years.

100-543/50=89.14

Off topic: that calculation was done just by entering the calculation up to the “50": when I typed the = it completed the calculation.
