If you see only small changes in battery level when you return, your battery is probably good to go, and you've just been taxing it with a bit of overuse. Make a note of how much battery you have left when you stop using your computer, then just put it to sleep and step back.
If you think your battery is only, for instance, lasting half as long, might you be using your computer twice as much as you normally would? The 2018 MacBook Airs battery is still secured by glue, but this time around, Apple is providing tools to make it easier for authorized service technicians to replace the battery without having. Your display will be on longer, your Wi-Fi use will be higher, and you might even be taxing your processor more than normal. The battery alert only yesterday (2/20/18) let me know that my battery is 'Condition: Replace Soon.' So-yes. The initial days and weeks of owning a new MacBook will likely see higher than normal use. I use my Mac every single day, for hours on end.
After all, it's brand new, and you want to use your shiny new toy.īut that burst of additional use has its tradeoffs. Aside from any excess battery drain during setup, you're likely to expend a lot of power in your initial days with your new machine because you'll be using it more.
