Let’s Save that Battery Life on MacBook Laptops

Here are some things you can do to save battery life on your MacBook:

• Keep the screen brightness to about half unless you need more or less suitable lighting.

Typically your Mac will go into sleep mode but continue to consume power. However, a hibernation mode similar to Windows does exist until you push the power button again.

What you’ll want to do, is go into the terminal. Then, type:

sudo pmset -g | grep hibernatemode

You’ll want to type in your password. Following this, your terminal will tell you what hibernatemode you’re using. Typically, it’s going to be 3 although this could vary.

Go to system preferences, and then security and privacy. You’ll want to see if you have FileVault on under the FileVault tab between General and Firewall.

If FileVault is turned on, you’ll want to make hibernatemode 5, otherwise you’ll want to use hibernatemode 1 as follows:

sudo pmset hibernatemode 5

OR (when FileVault is turned off)

sudo pmset hibernatemode 1

Now, whenever you shut your MacBook laptop lid, it will go into hibernation!

If this doesn’t work properly for you try this:

sudo pmset -a hibernatemode 25

You’ll want to run:

pmset -g

in order to check if the settings were updated ^^

The hibernatefile should be updated to:

/var/vm/sleepimage

The hibernatemode should be updated to:

25

I’ll make corrections to this post in the future if my MacBook does not hibernate successfully.
