How to check iPhone battery's cycles

Want to check the battery cycle count of an iPhone? If you’ve ever wondered how well the battery on your iPhone has aged over time, you may find that checking the battery cycle count can help you get a rough idea of battery health and usage. Knowing how many battery cycles your iPhone has been through can help to determine if the devices battery is in good shape, or if it may be time to consider a replacement.

If you’re not aware what battery cycle count means, it’s a measure of the total number of times a battery is fully charged and depleted. For example, if you fully charged your iPhone to 100% all the way from zero, and then completely drained the battery, it means you’ve completed one battery cycle. Realistically, no one charges and uses their iPhones like that, so let’s say you depleted the battery on your fully charged iPhone to 20% in a day and then recharged it to 100%. The next day, when you deplete your battery to 80%, you’d essentially complete one battery cycle.

Battery cycle count can be useful to determine the battery health, and if you’re interested in knowing how your iPhone battery has fared, we’ll guide you through the necessary steps to check an iPhone’s battery cycles.

Checking the battery cycle count directly on an iPhone is not as easy as you may think. You’ll need to fiddle with some files to actually view the count. Let’s take a look.

Now you’ve learned how to check your iPhone’s battery cycles. Hopefully that wasn’t too hard, though admittedly this is not the most user friendly approach out there.

Once you’ve copy pasted the text within a note, your iPhone might start to slow down a little because of all that text, but please be patient and you’ll find things catch up and get back to normal after a moment or two.

* Note that if you do not see the log data, it may be because you have the iPhone data analytics feature turned off in the settings.

According to Apple, iPhone batteries are designed to retain up to 80% of its original capacity at 500 battery cycles. This is its peak performance capability. However, this is just a rough number, because it heavily depends on your charging habits. As you can see here, my iPhone X has been through a lot with over 1100 battery cycles in the past two and a half years. However, my battery health is still at 79% which is really impressive for the cycle count.

Before you compare your battery cycle count with your battery health, you might want to learn how you can check the battery health percent of your iPhone. Apple recommends you to replace the battery when it drops below 80%. If you’re using the same iPhone for 2 years or less, it’s likely that your battery would stay above 80% health unless you have bad charging habits. If you have a low battery cycle count and a low battery health percent, you may need to adjust how you use the devices battery.

We hope you found your iPhone’s battery cycle count, as it can be useful to know for troubleshooting battery issues. What numbers did you get and how does it compare to the battery health percent? Do you replace iPhone batteries or do you just tend to get a new iPhone every few years? And do you know of a better or easier method to getting battery cycle count on iPhone?

    If you’re willing to scroll and search a bit, you don’t have to do the copy-paste and find steps.
    Once you open the last log-aggregate file, scroll down about 80% of the way, there’s a large identical section of “battery.heatmap.charging”. Just above that section is where you can find the battery cyclecount. This works on my iPhone SE (2020 model).

    I don’t have this file “log-aggregated”.


    Incredibly useful to determine age.

    I don’t have a log-aggregated file.

    Is there a way to check the battery on an iPad?

    • Blao says:

      Yes this should work the same on iPad. Or use a computer with Coconut battery as others have recommended, I think that is easier and it works with iPad and iPhone.

  6. Fadi says:

    don’t have this file log-aggregated !

  7. Ian says:

    Coconut Battery app is not free anymore – AUD4.49.

  8. William Alan Thomas Clark says:

    There are no log-aggregate files listed under Analytics Data on my iPhone 7. Why?

  9. Hal says:

    Great tip…
    I also use the free Mac app Coconut Battery, which checks you mac laptop battery, and if an iOS device plugged in will tell you those details… including cycle count, design capacity and current capacity.
    Also saves the info in a running sheet.

    What about capacity remain?
