Now that we know some of the science behind lithium ion batteries and that they are consumable products, what are some ways you can keep your battery healthy? ![]() How Hot Environments Affect Your MacBook Battery Now, there are other things that contribute to battery longevity such as temperature and aging, but charge cycles are typically the main factor.īy the way, you can check how many charge cycles your MacBook has by clicking on the Apple logo in the top left corner, clicking about this Mac, system report, and selecting the power option. Current charge cycles on my M1 MacBook Air 2000 days is 5 and a half years of using my MacBook for 6-8 hours every day. If I continued to use my M1 MacBook Air like I do now, or 1 full charge cycle every 2 days, I’d be looking at potentially 2000 days until I reached that 1000 charge cycle rating. This doesn’t mean it will magically fail, or burst into flames, just that instead of 16 hours on average for the M1 MacBooks, you’ll get somewhere around 13 hours instead. According to Apple, at some point soon after 1000 cycles the battery will only charge to 80% of capacity. MacBook lithium ion batteries are rated at 1000 charge cycles. How do Charge Cycles Affect Your MacBook Battery? That is, they will be consumed slowly with day to day use and degrade over the years. ![]() It’s common knowledge that lithium ion batteries are consumable products. For me personally with about 6-8 hours of use each day, I can get over 2 days of run time from a single charge, or 1 full charge cycle every 2 to 3 days. If you have one of the new M1 MacBooks, you would know that the battery life on them is incredible. If you do the same thing the next day, you will have discharged a total of 100%, or 1 full charge cycle. Source: Appleįor example, you might use 50% of your battery’s capacity one day, then recharge it fully overnight. A charge cycle can take several days to complete. ![]() You complete one charge cycle when you’ve used (or discharged) an amount that equals 100% of your battery’s capacity. There’s something called a charge cycle, which helps explain this process. Now, every time these lithium ions move back and forth, the battery loses a very tiny percentage of it’s total capacity. You want it to stay relatively balanced, and not tip either side too much. Keeping a battery at 100% charge all the time puts stress on the cathode. This results in an even distribution of lithium ions between the anode and cathode. In an ideal world, a li-ion battery likes to stay at 50% charge. The way these batteries discharge is by lithium ions moving from the anode to the cathode through the electrolyte, or vice versa to charge. Energy is stored and released as lithium ions travel between these electrodes through the electrolyte. The anode and cathode are capable of storing lithium ions. Yes, some of the newer MacBooks use a lithium-polymer, or li-poly battery, but for the purpose of this video the difference between them is minimal.Ģ) a separator between the two electrodes andģ) an electrolyte that fills the remaining space of the battery. Traditionally, MacBooks use lithium-ion (shortened to Li-ion) batteries. Let’s start with discussing the battery on your MacBook and the technology behind it. Battery technology and it’s supporting software (for example macOS) has changed a lot over the last decade. I wanted to start by mentioning that there is a lot of information out there on this topic, and a lot of it is quite outdated. I’m going to tell you exactly how to care for the battery in your MacBook, how often you should charge it, what are some best practices, and should you unplug it when you’re not using it. If you already own or intend to own a MacBook at any point in the future, do yourself a favor and read this entire MacBook battery guide from start to finish. ![]()
