I've tried searching for a few days and can't seem to find another person with the same problem as me.

I've had my 15" mbp for a little over a year know, and for the first few months the battery worked as expected, and the health slowly diminished to around 80%. Then, it seems like overnight, the battery health dropped to around 40% about 2 months ago. I've tried calibrating with no success. But the weird thing is, on random charges the battery health will jump back up to 81%. Right now the battery is running normal, but it won't happen again for like another week. I feel that my battery is faulty, but with 350 cycles I don't think Apple will replace it. Has anyone had a problem like this?
