MacBook Battery

About battery cycles

When you use your MacBook’s 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.

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. Your battery is designed to retain up to 80% of its original charge capacity at its maximum cycle count. 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.

Cycle count limits

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.

Check the condition of your MacBook’s battery

To check the condition of your MacBook’s battery, click on the battery icon in the menu bar. You will see one of four conditions:

  • Normal:The battery is functioning normally.
  • Replace Soon:The battery is functioning normally but holds less charge than it did when it was new.
  • Replace Now:The battery is functioning normally but holds significantly less charge than it did when it was new. You can continue to use the battery until you replace it without harming your computer.
  • Service Battery:The battery isn’t functioning normally, and you may or may not notice a change in its behaviour or the amount of charge it holds. Take your computer in for service. You can continue to use your battery before it’s checked without harming your computer.

Getting the exact number

For most modern MacBook’s, Apple estimates the battery can last through 1,000 cycles. A cycle count means using all of your battery’s power and then fully recharging it, whether you drained your battery in one sitting or off and on over the course of a few days or weeks.

According to Apple, “your battery is designed to retain up to 80 percent of its original capacity at 1,000 complete charge cycles.” So, you can expect to continue past 1,000 cycle counts, just with diminishing returns in terms of battery life. If you want to find out where, exactly, your battery stands, use the System Report tool.

 

To check your current cycle count: Hold down the Alt key and click the Apple icon in the upper-left corner and then choose System Report. Next, click Power from the left panel and look for the number for Cycle Count under Health Information. My MacBook Pro has been through 1,190 cycle counts, so I’m comfortably over the limit but still not in Replace Now or Service Battery territory.
