Battery won't charge to 100%. Optimised battery charging has been turned off

Orange charging light stays on (MagSafe connection to apple-supplied charger) but won't charge to 100%.

Is there a problem with my mac and/or charger?

If I did check the optimised battery charging option then it would only charge to 80% if I generally only used it on the charger and not via battery.

Hi,

You'd better check your MacBook Pro with Apple Diagnostics if it reports battery related error.

Use Apple Diagnostics to test your Mac - Apple Support

Apple Diagnostics reference codes - Apple Support

If it doesn't help, contact Apple Support or make Genius Bar reservation if there is retail AppleStore near you or find local Apple Authorized Service Provider to be examined your MacBook Pro there.
