MacBook shuts down when not connected to a charger. What to do?

Dear all,

I have an issue with my MacBook Pro (2015) - even though the battery is 100% charged, the MacBook shuts down changing all the setting e.g. time and date every time I unplug the charger. Does anyone know what to do?

Thank you and best,

Olena

Hello OlenaR,

Thank you for using Apple Support Communities! I understand that your MacBook Pro powers off when not connected to a charger. It's important that your MacBook Pro have power when you expect it, and you've come to the right place for help.

Let's start by resetting the System Management Controller (SMC) on your MacBook Pro:

How to reset the System Management Controller (SMC) on your Mac - Apple Support

Batteries have a limited amount of charge cycles before they're considered to be consumed so if the behavior still occurs after the SMC reset, check the battery cycle count for your MacBook Pro following the steps here:

The following support article also has some troubleshooting steps relevant to your issue:

Specifically, check the health of your battery following this section:

To see the health of your battery, hold the Option key and click the battery icon in the menu bar to reveal the battery status menu. You'll see one of the following status indicators:

  • Normal: The battery is functioning normally.
  • Replace Soon: The battery is functioning normally but holds less charge than it did when it was new. You should monitor the health of the battery by checking the battery status menu periodically.
  • Replace Now: The battery is functioning normally but holds significantly less charge than it did when it was new. You can safely continue using your computer, but if its lowered charging capacity is affecting your experience, you should take it to an Apple Store or Apple-authorized service provider.
  • Service Battery: The battery isn’t functioning normally. You can safely use your Mac when it's connected to an appropriate power adapter, but you should take it to an Apple Store or Apple-authorized service provider as soon as possible.

Apple Diagnostics is also a great way to help isolate power related hardware issues:
