This week I noticed my battery in my laptop went from a ‘health’ of 85% down to 64%! My laptop is a MacBook Pro (bought in December last year).

I noticed it while in Starbucks wondering why the battery had gone from its usual 4 hours of life down to 2. I was quite worried when I Google’d to discover quite a few people with problem batteries. Then… I found the Apple Battery Calibration article.

Success! My battery is back up to 89% ‘health’ and I have a don’t have to spend the £99 that Apple like to charge for batteries.

I’ll be remembering to do this every couple of months from now on.
