The most recent iPhones present the units’ battery cycle rely, serving to customers monitor the long-term “well being” of the battery. Displaying this knowledge is easy, although it’s considerably hidden.
As well as, you possibly can examine when the iPhone 15 or 16 was manufactured and first activated. (Word: This doesn’t work with earlier iPhones.)
Batteries have a restricted lifespan
Diamonds are eternally however batteries usually are not. Lithium-ion batteries in telephones, laptops, and so on., inevitably put on out. Each comes with a restricted variety of instances it may be charged and discharged. A basic vary to anticipate is 300 to 500 cost cycles, however Apple makes use of such high-quality batteries within the iPhone 15 and 16 collection that you would be able to anticipate two or thrice that many cycles. Checking your iPhone battery cycle rely may give you perception into your utilization habits in addition to the battery’s well being.
Nevertheless, checking the iPhone battery cycle rely will not be as simple because it sounds. Merely plugging within the machine to cost doesn’t mark the beginning of a brand new cycle. That occurs solely after the entire battery’s energy has been expended.
“You could possibly use half of your laptop computer’s cost in in the future, after which recharge it absolutely,” Apple says in a assist doc about battery life in MacBooks. “In case you did the identical factor the subsequent day, it could rely as one cost cycle, not two. On this instance, it’d take a number of days to finish a cycle.”
Realizing what number of cycles a battery has been by offers a tough approximation of how closely the machine has been used — and due to this fact how a lot life it has left.

To examine your iPhone battery cycle rely, open the Settings app and scroll all the way down to the Battery part. Now faucet on Battery Well being. You’ll see Cycle Rely clearly listed. Additionally displayed in that part is the month the iPhone was manufactured, in addition to the month it was first used.
At one level, Apple buried the cycle rely data within the About part of the Settings app. Nevertheless, that made no sense and is now not true.
Monitoring iPhone battery well being
The iPhone battery cycle rely serves as an approximate means of figuring out the well being of a battery. Subtracting the variety of cycles already used from the estimated lifetime expectation offers a basic sense of how for much longer a battery will perform. And the expectation is excessive: “Batteries of iPhone 15 fashions are designed to retain 80% of their authentic capability at 1000 full cost cycles beneath supreme situations,” Apple says.
Nevertheless, iPhone customers don’t must rely upon this one methodology. You possibly can look in Settings -> Battery -> Battery Well being to see how a lot utilizing the iPhone has lowered the overall quantity of energy it might probably retailer. That’s the Most Capability entry. The rule of thumb is {that a} battery that gives lower than 80% of most capability ought to be changed.
Within the instance within the screenshots above, the iPhone 15 has undergone 232 charging cycles since September 2023, and its Most Capability is at 98%. That offers the handset a Regular battery degree.
We initially printed this text on methods to examine your iPhone battery cycle rely on October 6, 2023. We up to date the knowledge.
