Battery percentage is different at login screen
Hi,
Everytime I boot up my MacBook Pro , the battery percentage reading is different at the login screen than after I login .Is there something wrong with my battery.
Like at my login screen the percentage is 94% but after i type my password and actually login, it changes to 96%
I'm at Yosemite 10.10.3
Thanks
MacBook Pro with Retina display, OS X Yosemite (10.10.3)
