Does anyone else have this issue? When I turn on my 2014 Retina Macbook Pro, the login screen shows my battery percentage but that battery percentage is at least five percent off compared to when I login. For example, the login screen shows 95%, but when I login, it shows me I'm at 100% which was correct. I had just unplugged it from the charger. Anyone else having this issue? I am using Yosemite.
