I always keep an eye on my MacBook's battery percentage—especially since, as a developer, I run a lot of resource-intensive applications. I always want the battery percentage to show up in the macOS menu bar. There's nothing worse than your computer dying mid-task, forcing you to wrangle up your AC adapter and figure out where you left off.
With the release of Big Sur, macOS now hides battery percentage from the menu bar by default, even if you had it enabled previously. They also removed the right-click option from the menu bar that formerly showed it.
In this short guide, I'll show you how to show your Mac's battery percentage in the menu bar in macOS Monterey and macOS Big Sur and get your Mac's battery percentage back.
