Signs of MacBook battery wear

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.
