Apple’s new iPhone 15 series lets you view the number of times the smartphone’s battery has been cycled.
This means it’s now possible to see how often your iPhone 15 Pro/Pro Max or iPhone 15/iPhone 15 Plus has been charged. You can find the information by navigating to, ‘Settings,’ ‘General’ and ‘About.’ Scroll to the bottom of the page, and you’ll see a new section on the About screen that includes ‘Cycle Count.’
As you can see from the screenshot below, the iPhone 15 Pro I’m currently using has been charged a total of three times.
A charge cycle is counted every time you lower the smartphone’s battery entirely, though it doesn’t have to happen all at once, per Apple’s battery information page:
“Charge your Apple lithium-ion battery whenever you want. There’s no need to let it discharge 100% before recharging. Apple lithium-ion batteries work in charge cycles. You complete one charge cycle when you’ve used (discharged) an amount that equals 100% of your battery’s capacity — but not necessarily all from one charge. For instance, you might use 75% of your battery’s capacity one day, then recharge it fully overnight. If you use 25% the next day, you will have discharged a total of 100%, and the two days will add up to one charge cycle.”
According to MacRumors, finding your iPhone’s Cycle Count has been available through third-party apps, but not directly in iOS. It’s been possible to view an iPhone battery’s ‘Maximum Capacity for a few years now to determine if a replacement is required.
