Understanding how Apple Li-ion batteries work and perform over time can help you maximize battery life while maintaining maximum power efficiency for as long as possible. Learn how to keep your Mac’s battery healthy by tracking usage, charge cycles, and battery life cycle health.
The lithium-ion battery in most MacBook models is designed to retain 80 percent of its original capacity after 1,000 charge cycles. After the battery is 100% discharged, you perform a charge cycle. You can check the cycle limit for your Mac’s battery by visiting Apple’s battery support page.
For example, if you drained 50% of the battery before returning it to 100%, you were only halfway through the charge cycle. It is recommended that you charge your Mac’s battery for as long as possible to reduce the number of charge cycles.
Mac batteries are consumables that degrade over time. Your Mac will display one of two battery status indicators:
RECOMMENDED SERVICE: The battery inside your Mac laptop cannot hold as much power as its original capacity, or it is not working properly. Currently, you may also see the status “Maintenance Now” instead of “Recommended Service”. Take your Mac to an Apple Authorized Service Provider or Apple Store for battery repair or replacement. You can fix battery maintenance warnings with a few simple steps.
To better monitor battery life, you can add a percentage indicator next to the battery icon in the menu bar. to this end:

Will not. This practice actually puts unnecessary stress on your Mac’s battery as it often results in more charge cycles in a shorter period of time. All lithium-ion batteries have a slightly reduced capacity after each full charge cycle, so regularly draining your Mac battery before charging it can quickly reduce battery life.
Apple Li-Ion batteries charge up to 100% in two stages, extending battery life. This process is called optimized battery charging. In stage 1, the battery is rapidly charged to 80% capacity. In stage 2, the battery enters a slow charge or “trickle charge” state until it reaches 100% capacity. In rare cases, your Mac may need to cool down before it can charge above 80%. Thankfully, Apple provides recommended ambient temperature recommendations for all MacBooks on its battery support website.
