My MBP battery will lose 25% randomly while running on battery power. Basically it'll be humming along around 60% then 10 minutes later I'll look up and my battery will be red in the 20-30% range.
If I open up Coconut Battery my max capacity will be around 75%.
After letting the battery run down to 0% and shut off, I'll wake the computer and see that it still has 25-30% battery, and an hour of charge left. Coconut Battery will show my max capacity at 100% again.
Does this happen to anybody else? I'm thinking of calibrating the battery after letting it run out, but this is annoying. I'm at work and I need to use the laptop for another few hours... this is the 3rd time this has happened in the past few weeks.
