    I have a mid2012 macbook pro 15" which battery health keeps changing randomly: 33%, 37%, 75%, 85%, 82%, back to 37%.
    I have reseted the PRAM and the SMC many times but the issue is still there.
    I started having this issue when I downgraded from Yosemite to Mavericks. so, i thought that Mavericks is the problem then I reverted back to Yosemite but the battery is still behaving weird.
    I hope someone can help me fix it. Thx in advance

    The battery is a bit on the young side to be flaking out, but it can happen. I'd get it diagnosed at an Apple store.

    Thank you fo
    Thank you for your reply. I used coconut battery to check the battery is from 2012. I am in Africa, so no apple store for me here. I am just trying to figure out what is wrong.
