Check your Mac’s battery health

If you have tried everything to resolve the issue of battery drain in sleep mode but it has not worked, the battery may be the culprit.

As batteries age, they lose some of their power. Batteries lose power and are less able to hold energy. Even when your laptop sleeps, the battery will drain faster. Apple provides a simple way to check the battery health of your MacBook.

Turn off the Power Nap feature

Stopping the Power Nap function on Intel-based Macs can save you battery life if you’re experiencing battery drain when in sleep mode.

Power Nap allows you to check email or make backups in the background even when your MacBook is on battery. This can be useful, but it also drains your MacBook’s batteries constantly. Do this to turn off Power Nap.

  1. Select System settings by clicking the Apple Logo (◊).
  2. Go to battery and click options.
  3. Click the dropdown next to Enable power nap.
  4. Choose Never or Only for Power Adapter.
