In macOS Catalina 10.5.5 or later, you can turn on optimized battery charging to help reduce battery aging. In this example, it might take several days to complete a cycle.īatteries 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. If you did the same thing the next day, it would count as one charge cycle, not two. A charge cycle happens when you use all of the battery’s power-but that doesn’t necessarily mean in a single charge.įor example, you could use half of your laptop's charge in one day, and then recharge it fully. Otherwise, you should plan to replace the battery as the battery count nears 1,000.When you use your Mac laptop, its battery goes through charge cycles. If you are buying a used Mac released later than 2010 and would like to continue to use your Mac for 3 years or more, we recommend purchasing a Mac with 300 battery cycles or fewer. Otherwise, it's important to note that the battery will need replacing when it gets close to 1,000 charges If you are buying a used Mac released after 2010 and plan to use one for at least three years, we recommend getting one with 300 or less cycles. Otherwise, a battery reporting over or approaching 1000 cycle counts is likely at or near it’s time to be replaced. This is impacted by the age of the original battery, so the age of the laptop should always be kept in mind. Whether your current Mac or a used Mac you are buying, a battery with less than 300 cycles should be expected to still deliver reasonable run-time performance. A battery that is older, but with fewer cycles can actually have less run time capacity than a fresher battery that has more run time cycles due to the impact of ‘exercise and use’ on battery health. It also depends on how the laptop has been used. What is a good battery cycle count for Mac batteries?Ī good battery cycle count for Mac batteries largely depends on how many years you plan to use the Mac in question before replacing the battery.
