Battery Cycle Count Exceeded | Every MacBook battery has a limited number of charge cycles. |
macOS Issues or Bugs | Software glitches can cause excessive battery drain. |

Quick Fixes for a MacBook Battery That Drains Quickly
If you’re looking for a fast solution, use this table for quick troubleshooting steps:
Issue | Quick Fix |

If these quick fixes don’t work, follow the detailed troubleshooting steps below.
If your MacBook is not holding charge, follow these troubleshooting steps to improve battery performance.

Check Battery Health Status
Before troubleshooting, check your MacBook’s battery condition:
- Click the Apple menu and select About This Mac.
- Go to System Report > Power.
- Find Cycle Count and Battery Condition.
- If the condition shows “Replace Soon”, “Service Battery,” or “Replace Now,” the battery is likely degraded.
If your battery health is poor, consider replacing it. If the condition is normal, continue troubleshooting.
Adjust Screen Brightness & Energy Settings
- Lower screen brightness by pressing F1 or using the Control Center.
- Open System Settings > Battery and enable Low Power Mode.
- Set Turn Display Off After to 2–5 minutes.
- Disable Keyboard Backlight if not needed.
Reducing brightness and adjusting power settings can extend battery life significantly.
Close Unnecessary Apps & Background Processes
Certain apps consume a lot of battery power even when not in use. To check:
- Open Activity Monitor (
Command + Space
→ type Activity Monitor). - Click on the Energy tab.
- Look for high battery-consuming apps.
- Close unnecessary apps by selecting them and clicking “Quit Process”.
Reset the System Management Controller (SMC)
If your MacBook battery drains quickly, resetting the SMC may help:
For MacBooks with an Apple T2 chip (2018 & later):
- Shut down your MacBook.
- Hold Control + Option (Left) + Shift for 7 seconds.
- While holding these keys, press the Power button for another 7 seconds.
- Release all keys and turn on your MacBook.
For Older MacBooks (Intel-based, no T2 chip):
- Shut down your MacBook.
- Hold Shift + Control + Option (Left side) + Power for 10 seconds.
- Release all keys and turn on your MacBook.

Update macOS & Reset PRAM/NVRAM
Software bugs can cause battery drain. Updating macOS may fix this:
- Go to System Settings > General > Software Update.
- Install any available macOS updates.
Resetting PRAM/NVRAM can also help:
- Shut down your MacBook.
- Turn it on and immediately press Command + Option + P + R.
- Hold for 20 seconds and release when the Apple logo appears.

If your MacBook battery continues to drain quickly despite following these steps, a replacement may be necessary. Signs that indicate you need a new battery include:
❌ Battery health below 80% in System Report.
❌ MacBook turns off suddenly even when charged.
❌ Swollen battery causing trackpad issues.
❌ Battery condition states “Service Battery” or “Replace Now”.
