How To Adjust Screen Brightness To Battery Charge On macOS

Macbooks have an auto-brightness feature like iPhones and iPads. This auto-brightness feature adjusts the screen’s brightness according to the brightness of the room. It’s useful for preventing strain on your eyes. If you’ve ever had a chance to use a Windows machine though, you’ll know that in addition to auto-brightness, the OS also lets you set a specific brightness level for when you’re on battery power. To date, macOS doesn’t have anything like that. Meet Bittery; it’s an exceptionally clever app that can adjust screen brightness to battery charge levels. If you’re low on battery, it will dim your screen.

Screen Brightness To Battery Charge

Bittery doesn’t have an customization options. This is both good and bad. Good because it will work without you having to set anything up. Bad because it doesn’t let you set a minimum brightness level that your screen should not go below. It adds a battery icon to the menu bar and little else. There’s no way to hide the icon. To quit Bittery, click the menu bar icon and select the quit option.

Energy  Saver Features

If you’re looking to make your battery last longer when you’re on the go, you should also look into the Energy Saver options that macOS natively supports. Again, they’re nothing like the power plan management that Windows has had for years but they’re something. The Energy saver options allow you to put hard disks to sleep, choose when your system sleeps and when your display sleeps when you’re running on battery power.

Apple prides itself on the battery life users can get from Macbooks but that shouldn’t mean the company can’t add better power managing tools to macOS. It doesn’t have to replicate what Windows has to offer. It can come up with something better or it can take hint from the Battery Saver mode it introduced in iOS a few years ago.

The battery saver mode in iOS works with auto-brightness so that you never have too dim a screen. It doesn’t dim your screen but it will override the default screen wake time on your iPhone or iPad and put the display to sleep sooner. At present, the battery saver mode on iOS has to be turned on by a user. iOS doesn’t let you automate it but that doesn’t make the feature useless or ill suited to be ported to macOS. If Apple were to port the feature to macOS, it would have to tweak things but users would generally appreciate being able to adjust more system settings when they’re on battery power.
