Diagnosing & Fixing MacBook Battery Issues
Your MacBook battery is one of the most important components for your device's longevity and performance. In this guide, we'll walk you through common battery issues, how to diagnose them, and when you need professional repair.
Common MacBook Battery Problems
Battery Won't Charge
If your MacBook is plugged in but not charging, the issue could be with the power adapter, charging cable, or the battery itself. Try resetting the SMC (System Management Controller) to resolve software-related charging issues.
Rapid Battery Drain
A battery that loses charge quickly may be nearing the end of its life. MacBook batteries typically retain 80% of their health after 1000 charge cycles. Use Coconut Battery to check your battery's health status.

If your MacBook becomes extremely hot or the battery swells, stop using it immediately and bring it to a professional. This is a safety hazard.
