Using El Capitan.
So basically I have an after market battery and charger, and it's charging extremely slowly, but draining very fast. Trying to figure if it's the battery or charger, or both. Or even whether the charger could be at fault, it's registering as a 60w charger but still charging slowly.
I've charged it to 100% and closed the lid, came back an hour and a half later and it's dead.
