If you wonder what apps are running battery on a Mac, you ought to switch to another app -- Activity Monitor, which allows you to get the battery consumption information in detail, no matter whether it is an app or a program. Once you run an app or program currently or let it work in a Mac background, Activity Monitor records the battery it spends automatically. Here we'll explain to you how to access that information:

Step 1: Launch Activity Monitor via Spotlight Search or Finder > Applications > Utilities > Activity Monitor.

Step 2: Use the Energy pane of the Activity Monitor located on the top menu bar to know the energy use of your Mac. You can monitor Mac's overall battery use and see details about the battery use of every app.

The Energy tab displays the App Name, Energy Impact, 12hr Power, App Nap, Preventing Sleep, and User information.

  • App Name: It refers to the app that uses battery or energy, which even can be an app plugin or a running program.
  • Energy Impact: It refers to the current energy/battery consumption of an app. Lower is better.
  • 12hr Power: It indicates the average energy impact of the app in the last 12 hours or since the Mac computer is booted, which only appears on Mac laptops.
  • App Nap: Whether the Apple Nap of an app is active.
  • Preventing Sleep: Whether this app is preventing your Mac from going to sleep. If an app shows Yes in the Preventing Sleep tab, it might be the culprit causing the Mac not to go to sleep when the lid is closed.
  • User: The user account running the app or program.

Intel Power Gadget is one of these applications. It is a software-based power usage monitoring tool developed by Intel Inc., which includes an application, driver, and libraries to monitor and estimate the real-time processor package power information in watts using the energy counters in the processor.

This app can only be used to obtain battery consumption after your Mac loads it successfully. This task should be performed in System Preferences> Security & Privacy > unlock the padlock by entering the user password > General > Details > check Intel Corporation Apps to allow Intel Power Gadget to load.

For the Mac soldered with M1, M2, or M3 chip, go to use MX Power Gadget instead as it is almost the same version of Intel Power Gadget. You can install it on your device and improve your MacBook's battery life using the statistics and information supplied by this fantastic tool.
