Help with the Macbook Pro's battery

Question

My macbook pro only charges at 82% maximum. When I continue to charge, the battery status icon in the menu bar is shown with the lightning, but it's still 82%. The indicator light when it reaches 82% is either green or off(there's no light at all). I bought this macbook pro in July last year. Can anyone tell me how to fix this?

Answer 1

Just use it - there are numerous tips from Apple:

Quite a few listed above.
You just want to treat the battery with some kindness - never let it run down to reserve power, plug it back in when you reach the 7-10% remaining point, if you don't use it for awhile, at least let it discharge to about 40% twice a month, etc. Since yours is likely a newer MBP, with the non-user replaceable batteries, you DON'T want to even attempt to 'calibrate' the battery - that's done in the factory and you just need to treat it kindly, NOT calibrate or re-calibrate.
That's about it. The battery is there to be used - just use it judiciously.
