Cycle count is a metric that measures the number of charge cycles an iPhone battery has gone through. A charge cycle is registered every time you deplete all of the batterys capacity, which degrades over time. Apple lithium-ion batteries work in charge cycles. You complete one charge cycle when youve used (discharged) an amount that equals 100% of your batterys capacity — but not necessarily all from one charge. For instance, you might use 75% of your batterys 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.
Knowing the cycle count of an iPhone battery is important because the batterys health affects how long the iPhone lasts between charges. A new battery should last for an extended period, but as it accumulates cycles, its performance may degrade. Checking the cycle count of an iPhone battery can help determine its condition and whether it needs to be replaced.
There are several ways to check the cycle count of an iPhone battery, including:
- Using the "Battery Health" feature in the iPhones settings
- Using a third-party app like CoconutBattery
- Using a shortcut called PowerUtil
It is recommended to check the cycle count of an iPhone battery once every few months if you have owned the device for several years.
