The iPhone 15 series will reportedly show the battery cycle count, helping users track the long-term “health” of the battery.
In addition, the Settings app displays when the device was manufactured and first activated.
Check the iPhone 15 battery cycle count
Li-ion batteries inevitably wear out. Each one comes with a limited number of times it can be charged and discharged. A very approximate range to expect is 300 to 500 charge cycles.
And iPhone 15 users can track that number. According to a post on X (formerly Twitter), the cycle count is listed in Settings -> General -> About. However, it’s not available on earlier models, only the new ones from 2023.

In addition, the General screen also lists the month the iPhone 15 was manufactured as well as when it was first used.
Tracking iPhone battery health
The battery cycle count is an approximate was of determining the health of a battery. Subtracting the number of cycles already used from the estimated lifetime expectation reveals how much longer a battery has.
But iPhone users don’t have to depend on an indirect method like this. Go to Settings -> Battery -> Battery Health & Charging to be shown how much using the iPhone has reduced the total amount of power it can store.
More about charge cycles
Every time you plug in the device isn’t the start of a new cycle.
“A charge cycle happens when you use all of the battery’s power — but that doesn’t necessarily mean in a single charge,” explains Apple. “For example, you could use half of your laptop’s charge in one day, and then recharge it fully. If you did the same thing the next day, it would count as one charge cycle, not two. In this example, it might take several days to complete a cycle.”
MacBook users can check their cycle count in System Information. However, Apple did not include the Battery Health & Charging feature on iPad.
