    Before update I had 100% connected to a 85w charger.
    After install was done I am at 97%, after 10 minutes I am at 92% with connected 85w charger?
    What is going on?

    Did the internal FAN kick in? Also Macrumors suggested user to check Activity monitor so you know what is running in the background to consume that many CPU cycles and eat up your power.
