First, turn on your Mac and open System Preferences. I like to do this from my dock, but you can also go to the Apple logo in the upper right-hand corner and select System Preferences there.
Next, click "battery." It is represented by the big, green battery, so you can't miss it!
Now, in the left-hand column, click battery again.
Finally, you can click and drag the toggle to the desired time. 5 minutes is my preferred time. Once you have chosen your selected sleep time, you are good to go!
Keep in mind that your sleep preferences can impact the life of your battery. So, it is best not to set your sleep timer to "never." If you want your battery to last throughout the day, try setting it for no more than 10 minutes.
Because your MacBook is so important for all that you do in a day, it is important to take good care of your Mac battery, monitor your Mac's battery health, and check the cycle count of your Mac's battery when to determine if your Mac needs a new battery. This might sound like a lot of maintenance, but checking your Mac's cycle count is an easy way to determine if your Mac needs a new battery, and it's actually incredibly simple. A battery's maximum cycle count is how many charge cycles your Mac can complete before the battery is no longer able to perform and will need replacing. In this guide, I show you how to check your Mac battery's cycle count and determine if your battery needs to be replaced.
