How to check the battery cycle count on MacsĪpple makes it easy to check the battery cycle count on Macs you just need to follow these instructions: That way you know why what you are buying seems to be a bargain and can plan in advance for a battery replacement.
This is why you need to know how to find the battery cycle count data, particularly if you are about to purchase a second-hand Mac notebook. They usually work way beyond that number (it’s kind of notional), but you may experience increasingly low battery life between charges until you end up with a notebook you have to plug into power to use. The company also says: “Your battery is designed to retain up to 80 percent of its original capacity at 1,000 complete charge cycles." The batteries used inside Macs are built to handle a number of battery cycles.Īpple advises that once your battery has used up all these cycles, it should be considered as needing replacement. That’s when I remembered this little-known, but really quite useful (and mercifully short), Mac tip that helps you get some kind of insight into your Mac’s battery health. That’s when I thought it might be worth sharing this little tip, given lots of people will be selling Macs to get hold of a new MacBook Air.

Those MacBooks come with fast charging - if you use Apple's 96W or 140W USB-C power adapter, and can charge from 0 to 50 percent in around 30 minutes.A friend of mine was considering purchasing an old(ish) MacBook Pro and wanted to check the battery life as they arranged the deal. The same applies even to the recently introduced MacBook Pro models (in a slightly enhanced way), despite the fact that their battery life is absolutely massive. That's what makes it safe to charge your MacBook Pro/Air overnight without having to worry about overcharging or damaging its battery. Then, it enters a 'trickle stage,' easing the electrical current to expand your notebook’s battery lifespan. This stage lasts until your battery reaches 80% of its current capacity.
The first stage is designed to charge your notebook’s battery as quickly as possible. That's because today's lithium-ion batteries go through two stages of charging. In 'modern' MacBook Pro and Air models (especially those running the latest macOS version), the chances of your notebook's battery overcharging are close to zero. With that said, let's explain this technology in greater detail.Ĭould Charging Your MacBook Overnight Overcharge Its Battery?

However, that’s no longer the case as today’s lithium-ion batteries (those that Apple uses in their products) come with optimized charging that’s designed to make your notebook’s battery last as long as possible.Īpple's optimized charging is a combination of hardware and software technologies, working completely automated and in the background. In the past, batteries used to be affected by how you would charge them (in addition to being easily affected by heat, physical damage, and more). Here’s Why Leaving Your MacBook Pro/Air Plugged-In Overnight Isn’t a Problem Anymore! With that said, make sure to keep on reading this article to learn more about the effects of leaving your MacBook Pro/Air plugged-in overnight. In recent years, Apple has done plenty to improve lithium-ion batteries that go inside their notebooks and smartphones, making them very stable and long-lasting. Of course, we’re talking about relatively new MacBooks here, made in 2015 and later.
