Signs of MacBook battery wear
- The MacBook shuts down unexpectedly.
- Battery life is much shorter than before.
- The trackpad or case appears raised, which may suggest swelling.
- The Mac only works reliably when plugged in.
- macOS shows service battery warnings.
Do not ignore swelling
Important: if the case, keyboard or trackpad area appears raised, stop using the device and seek advice. A swollen battery should be handled carefully.
Battery or charging fault?
Sometimes the issue is the battery; sometimes it is the charger, USB-C port or internal power circuitry. Diagnosis is important before replacing parts.
