I have a MacBook Pro late-2012 model. And my cable started showing symptoms of fraying. So I ordered an offbrand cable from Amazon with good reviews and it arrived today and I tried it and the Mac recognized that it was getting power but the percent won't go up it's stuck at 95% but when I click on the battery icon in the status bar it says Battery Is Charged same thing with the original MagSafe but I just noticed this behavior now. But with the MagSafe it would reach 98% sometimes and stop other times it would go to 100.
Should I just ignore this or do something?
