How To Fix MacBook Battery Draining In Sleep Mode?

Possible Causes

  1. Background Processes: Sometimes, applications or processes running in the background can prevent your MacBook from entering a low-power state during sleep mode, leading to excessive battery drain.
  2. Power-Hungry Apps: Certain apps may not be optimized for energy efficiency, causing them to consume more power than necessary even when the MacBook is in sleep mode.
  3. Settings Configuration: Incorrect settings, such as allowing Bluetooth or Wi-Fi to remain active during sleep, can contribute to increased power consumption. (Remove Water From IPhone Speakers)


  1. Check Activity Monitor:
    • Open Activity Monitor to identify any resource-intensive processes. Quitting unnecessary applications can help reduce battery drain during sleep.

  3. Adjust Energy Saver Settings:
    • Navigate to System Preferences > Energy Saver and customize settings to ensure your MacBook enters a low-power state during sleep.
  4. Disable Wake on Network Access:
    • In Energy Saver settings, uncheck the “Wake for network access” option to prevent your MacBook from waking up unnecessarily.
  5. Update macOS:
    • Ensure your MacBook is running the latest macOS version, as updates often include fixes for power management issues.
  6. Reset SMC:
    • Resetting the System Management Controller (SMC) can help resolve power-related issues. Follow Apple’s guidelines for your specific MacBook model.
