How to Check Power Consumption of Various Apps on Mac Device?

By Rimzhim Sharma December 30, 2016 How To, Mac

The battery of Mac devices is expected to last for long hours, but unfortunately sometimes a single application drains out the whole battery and discharges the device completely. In this case it is advisable to find the apps that drain out the most power and shut them down. Just like other devices Mac also keeps track of the amount of energy consumed by various apps. This helps you easily determine how much power is being consumed by applications and manage usage so your Mac doesn’t run out of fuel.

However, applications aren’t the only thing draining your device’s power. There are some hardware components such as Wi-Fi and Bluetooth etc. that affect battery consumption adversely.

Let’s have a look at how we can control the power consumption in our Mac device.

How to check if “Significant Energy” is consumed by apps:

There are basically 3 reasons of why an app gets listed in the “Significant Energy” list.

  1. If a particular application consumes more than the significant amount of energy i.e. more than the average power consumption.
  2. If you are using a single application for a longer duration like scrolling Facebook for long hours or maybe while playing a game of FIFA.
  3. The third reason for a app to come under this list is the inefficiency factor. Not all applications are self-capable of performing well, there are some apps which drains out a lot of battery due to their inefficient software.

If your battery seems to be draining faster than usual, then follow these steps:

a. Click on the battery icon on Mac’s menu bar.


b. Click the menu icon and a message of “Collecting Power usage information” will appear, shortly followed by a “Apps Using Significant Energy”.


c. If none of the applications are draining out a large amount of battery, then you will see a message of “No Apps Using Significant Energy” on the screen.

NOTE: In case you don’t see the battery icon then you can activate it by navigating to Menu>System preferences. Click the energy saver option and check “Show battery status in menu bar”.


How to view Power consumption of individual apps?

We can view the power consumption of individual apps via Activity Monitor. The Activity Monitor app in OS X lets you view important information about your Mac, including a list of apps that are draining valuable energy from your notebook’s battery

You can check the full list of apps and their energy consumption by this method:

  1. Under the “Apps using Significant energy” tab, click on any application’s name and open the Activity Monitor.
  2. You can open also Activity Monitor from the Applications folder or the “Other” folder in Launchpad.


  1. Now switch to “Energy tab” on the top of Activity Monitor window.
  2. Each application listed here shows an “Energy impact” score. Mac OS X calculates this score based on CPU, disk, and network usage, among other factors. The higher the number, the more impact the application has on your battery life.


  1. The next column shows the “Average Energy Impact” score, which shows you data based on the last eight hours your Mac was running.
  2. If a process is consuming too much energy, you can quit these processes by selecting them in Activity Monitor and then tapping the “x” button in the upper left corner.

The bottom line is that you should have a fair control of apps and the amount of power which they consume. Not only this but you can always follow some battery saving tips like dimming the display light, or switching off the Wi-Fi and Bluetooth when not in use. You can also prevent some apps to run in background at the time of startup to conserve power.
