Macos App Life Cycle

About battery cycles

When you use your Mac notebook, its battery goes through charge cycles. A charge cycle happens when you use all of the battery’s power—but that doesn’t necessarily mean a single charge.

The Simple Life(cycle) of a SwiftUI View. Rather, it’s helped me make the transition easier after developing native iOS apps for nearly 5 years now. My hope is that this could help. In iOS 12 and earlier, and in apps that don't support scenes, UIKit delivers all life-cycle events to the UIApplication Delegate object. The app delegate manages all of your app’s windows, including those displayed on separate screens. As a result, app state transitions affect your app's entire UI, including content on external displays.

For example, you could use half of your notebook'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 way, it might take several days to complete a cycle.

Batteries have a limited amount of charge cycles before their performance is expected to diminish. Once the cycle count is reached, a replacement battery is recommended to maintain performance. You can use your battery after it reaches its maximum cycle count, but you might notice a reduction in your battery life.

Knowing how many charge cycles your battery has and how many are left can help you determine when a battery replacement is required. For best performance, replace your battery when you reach its maximum cycle count.

Follow these steps to access information about your Mac notebook battery, including its cycle count:

  1. Hold the Option key and click the Apple  menu. Choose System Information.
  2. Under the Hardware section of the System Information window, select Power. The current cycle count is listed under the Battery Information section.

Identify your computer

Cycle count limits vary between Mac models. For help identifying your Mac notebook, use the Tech Specs page or these articles:

Use the table below to see the cycle count limit for your computer's battery. The battery is considered consumed once it reaches the limit.
