The old macOS battery menu bar item that used to show time remaining

Remember this?

Apple took it away. We brought it back.



Introducing MacBat: it continuously calculates how much time your battery should still last, using a proprietary algorithm that factors in your Mac's real power usage.

But that's just the beginning.

The interface a Mac deserves

MacBat isn't just another menu bar item.

It's a living, functional control surface, based on Apple's guidelines, that puts the information that matters right at your cursor.

Your Mac already knows how to save battery.

Your processes, not always.

New Control power-saving mode.

Using the Sentinel function, MacBat tracks less important processes that are hogging resources and cuts their CPU usage without affecting performance.

Goodbye hot Mac and draining battery!

There's a Sentinel in your Mac.

The same process-control technology can be used in standalone mode.

What's more: you can manually set which ones the Sentinel takes over and assign processes only to the high-efficiency cores, cutting consumption even further.
