Batteries allows you to track all of your devices’ batteries (your Mac, iPhone/iPad/iPod, AirPods and bluetooth devices) from one place. When any of your devices are running low on battery, you’ll receive a low battery notification.

With the menu bar app, you receive an alert when your MacBook is plugged in or unplugged, and when your battery percentage reaches a preset level, so you know when to plug in your computer to keep it from dying or to unplug it and save your battery life.

CoconutBattery shows you live information about the battery quality in your Mac, iPhone and iPad. You can also save the current health information, so you can see the changes of your battery over time.

Battery Indicator puts your remaining battery time right in the menu bar, so you know how long you have before the hunt for a charger begins. Prefer a percentage? That works too. Plugged in, it tells you how long until you’re fully charged, or it simply steps aside until you unplug.

Turbo Boost Switcher gives you direct control over your Mac’s performance, toggling Turbo Boost on or off to reduce heat and extend battery life. Monitor CPU stats at a glance.
