I bought my 13-inch MacBook Air in August 2020 and recently, like in the past week or 2, it started having the same problem. It randomly shuts down. I try restarting it but I think it just decides to restart on its own, sometimes with the cover closed.

A couple of different symptoms can come along with having a battery percentage meter on your Mac that is inaccurate. The most obvious one is your computer randomly shutting off and dying before the battery percentage hits zero percent or even gets low. The other is a perceived sense of quick battery drain or a drop in the lifespan of a battery.

If you suspect that the battery on your Mac is displaying an inaccurate percentage of battery life remaining, try some of these at-home solutions to reset or recalibrate the battery. Otherwise, a Genius Bar appointment at your local Apple store might be necessary.

Reset the System Management Controller (SMC)

The System Management Controller, or SMC, on your Mac is buried within the operating system and groups together various functions involving the display, battery power, booting, shutting down, sleeping, and more. If something gets out of whack with your battery indicator, resetting the SMC could refresh the battery percentage so it's accurate again.

How to reset the SMC depends on the type of Mac you own. If you have an older Mac notebook with a removable battery, the first thing you'll want to do is shut down the computer and disconnect it from a power source. Remove the battery. Then, press and hold the power button for five seconds while the battery is still out of the machine. Insert the battery again, connect the laptop to a power source and turn it back on.

If you have a newer MacBook model without a removable battery, the procedure is a bit different. Shut down the computer, but plug it in to a power source while off. Press the Shift, Control, Option and power keys all at the same time — the former three must be the keys on the left side of the keyboard.

Closely monitor the battery percentage your Mac displays relative to your usage over the next day or two and observe if the SMC reset fixed the problem.

Calibrate Your Mac's Battery

Not only is keeping your battery calibrated important so that the battery percentage on your Mac stays accurate, but it's vital for optimal battery health over years and charge cycles.

Battery calibration is easier than you might think. Samsara gps demo. You should basically just use your computer like you normally do, except let the battery show off every bit of its power. First, plug in your Mac to a power source and charge it to full capacity, 100 percent. After fully charged, leave it plugged in for about two hours so it sits at a 100-percent charge.

Unplug the Mac and start using it, letting the battery drain naturally. Eventually the battery will get low, so let it drain until the computer automatically goes to sleep. Once it's been asleep for a few minutes, plug the charging cable into your MacBook and recharge the computer back to 100 percent.

This entire cycle is what calibrates the battery. Once the MacBook is recharged again, unplug the charging cable and notice as you use the machine whether the battery percentage appears to be more in sync with your usage.
